When the explrers first set ft upn the cntinent f Nrth America, the skies and lands were alive with an astnishing variety f wildlife. Native Americans had taken care f these precius natural resurces wisely. Unfrtunately, it tk the explrers and the settlers wh fllwed nly a few decades t decimate a large part f these resurces. Millins f waterfwl ( 水 禽 ) were killed at the hands f market hunters and a handful f verly ambitius sprtsmen. Millins f acres f wetlands were dried t feed and huse the ever-increasing ppulatins, greatly reducing waterfwl habitat.
In 1934, with the passage f the Migratry Bird Hunting Stamp Act (Act), an increasingly cncerned natin tk firm actin t stp the destructin f migratry ( 迁徙的) waterfwl and the wetlands s vital t their survival. Under this Act, all waterfwl hunters 16 years f age and ver must annually purchase and carry a Federal Duck Stamp.

Since 1934, better than half a billin dllars has gne int that Fund t purchase mre than 5 millin acres f habitat. Little wnder the Federal Duck Stamp Prgram has been called ne f the mst successful cnservatin prgrams ever initiated.

【答案】28. A 29. C 30. D 31. A
【解析】本文是一篇说明文。本文讲述了美国鸭票的故事，由于美国移民的大量流入，对于农地和住房的急需大量的水禽栖息地被破坏导致美国水禽骤减，因此美国发行了鸭票，狩猎者只有购买了鸭票才能狩猎，而鸭票的部分收入进入到了用于购买水禽栖息地的基金，从而保护了水禽。
【28题】细节理解题。根据第一段“Millins f acres f wetlands were dried t feed and huse the ever-increasing ppulatins, greatly reducing waterfwl habitat.”可知，上百万公顷的湿地被抽干用作农地或者修建住房，极大地减少了水禽的栖息地，故可知，栖息地的减少导致了水禽数量的下降，故选A。
【29题】词义猜测题。根据前一句“Native Americans had taken care f these precius natural resurces wisely.”可知，北美的土著人把这些珍贵的自然资源保护的很合理，本句中的“Unfrtunately”可知，本句与上一句形成了转折，前一句陈述北美土著人做的好的地方，故可知，本句阐述移民者做的不好的地方，即移民者破坏了这些自然资源，故画线词意思是“破坏”。A. Acquire获得；B. Exprt出口；C. Destry破坏；D. Distribute分配。故选C。
【30题】推理判断题。根据最后一段“Since 1934, better than half a billin dllars has gne int that Fund t purchase mre than 5 millin acres f habitat.”可知，自1934年起，超过5亿美元进入到了这个基金会，购买了超过500万公顷的水禽栖息地，故可以推出，通过发行鸭票，美国政府获得了大量的资金，故选D。
【31题】主旨大意题。根据全文可知，由于之前不恰当的发展导致美国水禽骤减，因此美国发行了鸭票，狩猎者只有购买了鸭票才能狩猎，而鸭票的部分收入进入到了用于购买水禽栖息地的基金，从而保护了水禽，故可知，本文讲述美国鸭票的故事，故选A。
2.（2021年新高考I卷）D
Ppularizatin has in sme cases changed the riginal meaning f emtinal (情感的) intellingence. Many peple nw misunderstand emtinal intelligence as almst everything desirable in a persn's makeup that cannt be measured by an IQ test, such as character, mtivatin, cnfidence, mental stability, ptimism and “peple skills.” Research has shwn that emtinal skills may cntribute t sme f these qualities, but mst f them mve far beynd skill-based emtinal intelligence.
We prefer t describe emtinal intelligence as a specific set f skills that can be used fr either gd r bad purpses. The ability t accurately understand hw thers are feeling may be used by a dctr t find hw best t help her patients, while a cheater might use it t cntrl ptential victims. Being emtinally intelligent des nt necessarily make ne a mral persn.
Althugh ppular beliefs regarding emtinal intelligence run far ahead f what research can reasnably supprt, the verall effects f the publicity have been mre beneficial than harmful. The mst psitive aspect f this ppularizatin is a new and much needed emphasis (重视) n emtin by emplyers, educatrs and thers interested in prmting scial well-being. The ppularizatin f emtinal intelligence has helped bth the public and researchers re-evaluate the functinality f emtins and hw they serve peple adaptively in everyday life.
Althugh the cntinuing ppular appeal f emtinal intelligence is desirable, we hpe that such attentin will excite a greater interest in the scientific and schlarly study f emtin. It is ur hpe that in cming decades, advances in science will ffer new perspectives (视角) frm which t study hw peple manage their lives. Emtinal intelligence, with its fcus n bth head and heart, may serve t pint us in the right directin.
32. What is a cmmn misunderstanding f emtinal intelligence?
A. It can be measured by an IQ test.B. It helps t exercise a persn’s mind.

33. Why des the authr mentin “dctr” and “cheater” in paragraph 2?
A. T explain a rule.B. T clarify a cncept.
C. T present a fact.D. T make a predictin.
34. What is the authr’s attitude t the ppularizatin f emtinal intelligence?
A. Favrable.B. Intlerant.
C. Dubtful.D. Unclear.
35. What des the last paragraph mainly talk abut cncerning emtinal intelligence?

【32题】细节理解题。通过文章第一段“Research has shwn that emtinal skills may cntribute t sme f these qualities (研究表明，情商技巧可能有助于这些品质的形成)”可知，情商指的并不是一个人的积极品质。故选D项。
【33题】推理判断题。通过文章第二段“The ability t accurately understand hw thers are feeling may be used by a dctr t find hw best t help her patients, while a cheater might use it t cntrl ptential victims. (医生可能利用这种准确理解他人感受的能力来找到最好的帮助病人的方法，而骗子可能利用这种能力来控制潜在的受害者)”可推知，作者在文章第二段中提到“医生”和“骗子”是举例子来阐明下文的观点——情商高并不一定能使一个人成为有道德的人。故选B项。
【34题】推理判断题。通过文章第三段“the verall effects f the publicity have been mre beneficial than harmful. …The ppularizatin f emtinal intelligence has helped bth the public and researchers (宣传的总体效果一直是利大于弊。这种普及最积极的方面是雇主、教育者和其他对促进社会福利感兴趣的人对情感进行了新的、迫切需要的强调。情商的普及帮助了公众和研究人员)”可推知，作者认为情商普及是对人们有利的。故选A项。
【35题】推理判断题。通过文章最后一段“we hpe that such attentin will excite a greater interest in the scientific and schlarly study f emtin. It is ur hpe that in cming decades, advances in science will ffer new perspectives frm which t study hw peple manage their lives. (我们希望这种关注将激发人们对情感科学和学术研究的更大兴趣。我们希望在未来的几十年里，科学的进步将为研究人们如何管理自己的生活提供新的视角)”可推知，本段主要谈了对未来关于情商研究的期望。故选B项。

5.（2021年全国乙卷）B
When almst everyne has a mbile phne, why are mre than half f Australian hmes still paying fr a landline（座机）?
These days yu’d be hard pressed t find anyne in Australia ver the age f 15 wh desn’t wn a mbile phne. In fact plenty f yunger kids have ne in their pcket. Practically everyne can make and receive calls anywhere, anytime.
Still, 55 percent f Australians have a landline phne at hme and nly just ver a quarter （29%） rely nly n their smartphnes accrding t a survey （调查）. Of thse Australians wh still have a landline, a third cncede that it’s nt really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case f emergencies. I think my hme falls int that categry.
Mre than half f Australian hmes are still chsing t stick with their hme phne. Age is naturally a factr（因素）— nly 58 percent f Generatin Ys still use landlines nw and then, cmpared t 84 percent f Baby Bmers wh’ve perhaps had the same hme number fr 50 years. Age isn’t the nly factr; I’d say it’s als t d with the makeup f yur husehld.
Generatin Xers with yung families, like my wife and I, can still find it cnvenient t have a hme phne rather than prviding a mbile phne fr every family member. That said, t be hnest the nly peple wh ever ring ur hme phne are ur Baby Bmers parents, t the pint where we play a game and guess wh is calling befre we pick up the phne（using Caller ID wuld take the fun ut f it）.
Hw attached are yu t yur landline? Hw lng until they g the way f gas street lamps and mrning milk deliveries?
24. What des paragraph 2 mainly tell us abut mbile phnes?
A. Their target users.B. Their wide ppularity.

【分析】本文是一篇说明文。文章主要介绍了澳大利亚使用固定电话的情况，并且表达了固定电话是非必需品的观点。
【24题】主旨大意题。根据文章第二段“These days yu'd be hard pressed t find anyne in Australia ver the age f 15 wh desn't wn a mbile phne. In fact plenty f yunger kids have ne in their pcket. Practically everyne can make and receive calls anywhere, anytime. (现在你很难在澳大利亚找到15岁以上的没有手机的人。事实上，很多年幼的孩子口袋里都有手机。几乎每个人都可以随时随地拨打和接听电话)”可推知，本段主要说明手机在澳大利亚广受欢迎。故选B项。
【25题】词句猜测题。根据划线单词的上文“Of thse Australians wh still have a landline (在那些仍然有固定电话的澳大利亚人中)”可知，这个调查的目标人群是仍然有固定电话的澳大利亚人；根据下文“it's nt really necessary and they're keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case f emergencies (固定电话并不是必须的，他们将其作为一种安全保障——19%的人表示他们从未使用过固定电话，另有13%的人保留固定电话以防紧急情况)”可知，很多人认为固定电话并不是必须拥有的，有些人保留固定电话只是为了防止紧急情况。从而推知，在调查中，他们应该是承认了固定电话的非必要性。由此推知，划线单词“cncede”意为“承认”。故选A项。
【26题】推理判断题。根据文章第四段“84 percent f Baby Bmers wh've perhaps had the same hme number fr 50 years.(婴儿潮时代中有84%的人可能已经有50年相同的家庭号码了)”以及文章第五段“That said, t be hnest the nly peple wh ever ring ur hme phne are ur Baby Bmers parents (也就是说，老实说，唯一打过我们家电话的人是婴儿潮一代的父母)”可推知，婴儿潮时代的人一直用固定电话。故选C项。
【27题】推理判断题。根据文章最后一段“Hw attached are yu t yur landline? Hw lng until they g the way f gas street lamps and mrning milk deliveries? (你有多喜欢你的座机？它们还要多久才能走上煤气路灯和早晨送牛奶的道路？)”可推知，本段使用类比的方式，使用煤气路灯以及早晨送牛奶已经被淘汰的例子，侧面说明了固定电话总有一天会废弃的。故选B项。

Yu’ve heard that plastic is plluting the ceans — between 4.8 and 12.7 millin tnnes enter cean ecsystems every year. But des ne plastic straw r cup really make a difference? Artist Benjamin Vn Wng wants yu t knw that it des. He builds massive sculptures ut f plastic garbage, frcing viewers t re-examine their relatinship t single-use plastic prducts.
At the beginning f the year, the artist built a piece called “Strawpcalypse,” a pair f 10-ft-tall plastic waves, frzen mid-crash. Made f 168,000 plastic straws cllected frm several vlunteer beach cleanups, the sculpture made its first appearance at the Estella Place shpping center in H Chi Minh City, Vietnam.
Just 9% f glbal plastic waste is recycled. Plastic straws are by n means the biggest surce（来源）f plastic pllutin, but they’ve recently cme under fire because mst peple dn’t need them t drink with and, because f their small size and weight, they cannt be recycled. Every straw that’s part f Vn Wng’s artwrk likely came frm a drink that smene used fr nly a few minutes. Once the drink is gne, the straw will take centuries t disappear.
In a piece frm 2018, Vn Wng wanted t illustrate（说明） a specific statistic: Every 60 secnds, a trucklad’s wrth f plastic enters the cean. Fr this wrk, titled “Trucklad f Plastic,” Vn Wng and a grup f vlunteers cllected mre than 10,000 pieces f plastic, which were then tied tgether t lk like they’d been dumped（倾倒） frm a truck all at nce.
Vn Wng hpes that his wrk will als help pressure big cmpanies t reduce their plastic ftprint.

D. Ocean Plastics Transfrmed int Sculptures
【答案】28. C 29. A 30. C 31. D
【解析】
【分析】本文是一篇说明文。文章介绍了艺术家Benjamin Vn Wng用塑料垃圾制作了一个巨大的雕塑作品，让人们通过这个雕塑重新审视自己与一次性塑料制品的关系。此外他在2018的一件作品“Trucklad f Plastic”说明了每60秒，就有一卡车塑料进入海洋。Vn Wng通过用塑料垃圾制造巨型雕塑来唤醒和提高人们的环保意识。
【28题】推理判断题。根据第一段“But des ne plastic straw r cup really make a difference? Artist Benjamin Vn Wng wants yu t knw that it des. He builds massive sculptures ut f plastic garbage, frcing viewers t re-examine their relatinship t single-use plastic prducts.(但一根塑料吸管或一个塑料杯真的有什么区别吗？艺术家本杰明·冯·王（Benjamin Vn Wng）想让你知道，它确实如此。他用塑料垃圾建造巨大的雕塑，迫使观众重新审视他们与一次性塑料产品的关系。)”可知，Vn Wng用塑料垃圾制作的雕塑想让人们重新审视与一次性塑料制品的关系，由此可知他做这个雕塑的目的是为了引起公众对塑料垃圾的关注。故选C项。
【29题】推理判断题。根据第三段“Just 9% f glbal plastic waste is recycled. Plastic straws are by n means the biggest surce(来源) f plastic pllutin, but they’ve recently cme under fire because mst peple dn’t need them t drink with and, because f their small size and weight, they cannt be recycled. Every straw that’s part f Vn Wng’s artwrk likely came frm a drink that smene used fr nly a few minutes. Once the drink is gne, the straw will take centuries t disappear.(全球只有9%的塑料垃圾被回收。塑料吸管绝不是最大的塑料污染源，但它们最近却受到了抨击，因为大多数人不需要吸管喝饮料，而且由于它们体积小、重量轻，无法回收利用。冯·王作品中的每一根吸管都很可能来自只喝了几分钟的饮料。一旦饮料消失了，吸管也要几个世纪才能消失。)”可知，吸管由于体积小，重量轻，无法回收利用，由此可推知，作者在第三段讨论吸管是为了展示它们回收的困难。故选A项。
【30题】推理判断题。根据倒数第二段“In a piece frm 2018, Vn Wng wanted t illustrate(说明) a specific statistic: Every 60 secnds, a trucklad’s wrth f plastic enters the cean. Fr this wrk, titled “Trucklad f Plastic,” Vn Wng and a grup f vlunteers cllected mre than 10,000 pieces f plastic, which were then tied tgether t lk like they’d been dumped(倾倒) frm a truck all at nce.(在2018年的一个作品中，冯·王(Vn Wng)想要说明一个具体的统计数字：每60秒，就有一卡车塑料进入海洋。这项名为“一卡车塑料”的作品，冯·王和一组志愿者收集了一万多块塑料，然后把它们绑在一起，让它们看起来像是同时从卡车上倾倒下来的。)”可知，这个作品以创新的方式让人们了解到塑料垃圾以很快的速度和很大的量倾入海洋，刷新了观众对海洋塑料污染的认知，由此可推断，这个作品会让观众对塑料垃圾进入海洋这件事“耳目一新”。故选C项。
【31题】标题判断题。通读全文，结合第一段“But des ne plastic straw r cup really make a difference? Artist Benjamin Vn Wng wants yu t knw that it des. He builds massive sculptures ut f plastic garbage, frcing viewers t re-examine their relatinship t single-use plastic prducts.(但一根塑料吸管或一个塑料杯真的有什么区别吗？艺术家本杰明·冯·王(Benjamin Vn Wng)想让你知道，它确实如此。他用塑料垃圾建造巨大的雕塑，迫使观众重新审视他们与一次性塑料产品的关系。)”和倒数第二段“In a piece frm 2018, Vn Wng wanted t illustrate(说明) a specific statistic: Every 60 secnds, a trucklad’s wrth f plastic enters the cean. Fr this wrk, titled “Trucklad f Plastic,” Vn Wng and a grup f vlunteers cllected mre than 10,000 pieces f plastic, which were then tied tgether t lk like they’d been dumped(倾倒) frm a truck all at nce.(在2018年的一个作品中，冯·王(Vn Wng)想要说明一个具体的统计数字：每60秒，就有一卡车塑料进入海洋。这项名为“一卡车塑料”的作品，冯·王和一组志愿者收集了一万多块塑料，然后把它们绑在一起，让它们看起来像是同时从卡车上倾倒下来的。)”可知艺术家本杰明·冯·王(Benjamin Vn Wng)通过利用塑料垃圾制作巨型雕塑的方法来提示人们重新思考与一次性塑料的关系，唤醒和提高人们循环利用的意识，促进环保的发展。由此可知，D项“海洋塑料变成雕塑”符合文章主旨，适合作为标题。故选D项。

During an interview fr ne f my bks, my interviewer said smething I still think abut ften. Annyed by the level f distractin（干扰）in his pen ffice, he said, “That’s why I have a membership at the cwrking space acrss the street — s I can fcus”. His cmment struck me as strange. After all, cwrking spaces als typically use an pen ffice layut（布局）. But I recently came acrss a study that shws why his apprach wrks.
The researchers examined varius levels f nise n participants as they cmpleted tests f creative thinking. They were randmly divided int fur grups and expsed t varius nise levels in the backgrund, frm ttal silence t 50 decibels（分贝）, 70 decibels, and 85 decibels. The differences between mst f the grups were statistically insignificant; hwever, the participants in the 70 decibels grup — thse expsed t a level f nise similar t backgrund chatter in a cffee shp — significantly utperfrmed the ther grups. Since the effects were small, this may suggest that ur creative thinking des nt differ that much in respnse t ttal silence and 85 decibels f backgrund nise.
But since the results at 70 decibels were significant, the study als suggests that the right level f backgrund nise — nt t lud and nt ttal silence — may actually imprve ne’s creative thinking ability. The right level f backgrund nise may interrupt ur nrmal patterns f thinking just enugh t allw ur imaginatins t wander, withut making it impssible t fcus. This kind f “distracted fcus” appears t be the best state fr wrking n creative tasks.
S why d s many f us hate ur pen ffices? The prblem may be that, in ur ffices, we can’t stp urselves frm getting drawn int thers’ cnversatins while we’re trying t fcus. Indeed, the researchers fund that face-t-face interactins and cnversatins affect the creative prcess, and yet a cwrking space r a cffee shp prvides a certain level f nise while als prviding freedm frm interruptins.

【解析】
【分析】这是一篇说明文。作者通过自身经历讲述人们为什么不喜欢开放性办公室以及有关多少分贝的噪音最有利于人们的创造性思维的研究。
【32题】细节理解题。根据第一段“That’s why I have a membership at the cwrking space acrss the street - s I can fcus.（这就是为什么我在街对面的公用办公空间有会员资格——这样我就可以集中精力了。）”可知，采访者喜欢共享办公空间的原因是那里可以帮助他集中精力。故选A项。
【33题】细节理解题。根据第二段“The differences between mst f the grups were statistically insignificant; hwever, the participants in the 70 decibels grup - thse expsed t a level f nise similar t backgrund chatter in a cffee shp - significantly utperfrmed the ther grups.（大多数组之间的差异在统计学上是不显著的；然而，音量为70分贝的那组参与者（置身于类似于咖啡店背景噪音的环境中）的表现明显好于其他组。）”和第三段“But since the results at 70 decibels were significant, the study als suggests that the right level f backgrund nise - nt t lud and nt ttal silence - may actually imprve ne's creative thinking ability.（但由于70分贝的结果很显著，该研究还表明，适当的背景噪音——不要太大声，也不要完全安静——实际上可能会提高一个人的创造性思维能力。）”可知，70分贝的那组参与者表现好于其他组，所以70分贝的噪音背景环境更有可能促进创造性思维能力。故选C项。
【34题】细节理解题。根据最后一段“S why d s many f us hate ur pen ffices? The prblem may be that, in ur ffices, we can't stp urselves frm getting drawn int thers' cnversatins while we're trying t fcus. Indeed, the researchers fund that face-t-face interactins and cnversatins affect the creative prcess, and yet a cwrking space r a cffee shp prvides a certain level f nise while als prviding freedm frm interruptins.（那么，为什么我们中有那么多人讨厌开放式办公室呢？问题可能是，在我们的办公室里，当我们试图集中注意力时，我们无法阻止自己卷入别人的谈话中。的确，研究人员发现，面对面的互动和对话会影响创作过程，然而，共同工作空间或咖啡馆在提供一定程度的噪音的同时，也提供不受干扰的自由。）”可知，开放式办公室不受人们欢迎的原因是让我们不断地卷入别人的谈话中，受到很多干扰。故选D 项。
【35题】推理判断题。根据第一段“During an interview fr ne f my bks, my interviewer said smething I still think abut ften.（在一次采访我的一本书时，我的采访者说了一些我至今还经常想起的话。）”可知，作者提到有人采访自己的书，所以可以推断，作者是一位作家。故选D项。
8.（2021年天津卷）A trial prject by the Mntreal Children's Hspital suggested that the use f medical hypnsis(催眠)can reduce pain and anxiety in patients. The prject als resulted in a reductin in the amunt f medicines used t perfrm medical-imaging imaging(医学影像) prcedures.
“During the examinatin children dn't mve. It wrks perfectly. It's amazing,“ said Jhanne L'Ecuyer, a medical-imaging technlgist at the hspital.
The prject was inspired by a French team frm Ruen University Hspital Centre where examinatins are dne under hypnsis instead f general anesthesia(麻醉）.
A French medical-imaging technlgist-als a hypntist — was invited t train a few members in the medical-imaging department f the children's hspital. In all, 80 examinatins were cnducted fr the prject between January and September, 2019, fcusing n the imaging prcedures that wuld cause anxiety.
Hypnsis is nt a state f sleep: It is rather a mdified(改变的)state f cnsciusness. The technlgist will guide the patient t this mdified state—an imaginary wrld that will disassciate itself mre and mre frm the prcedure that fllws.
“The technlgist must build up a stry with the patient," Ms. L'Ecuyer said. "The patient is left with the pwer t chse what he wants t talk abut. D yu play sprts? D yu like ging t the beach? We establish a subject that we will discuss thrughut the prcedure."
Everything that happens next during the prcedure must be related t this stry — an injectin （注射）becmes the bite f an insect; the heat n the skin becmes the sensatin f the sun and a machine that rings becmes a plice car passing nearby.
“The imprtant thing is that the technlgist assciates what is happening utside the patient's bdy with what the patient sees in his head," Ms. L'Ecuyer said. "It requires creativity n the part f the technlgist, imaginatin, a lt f patience and kindness."
The prcedure appealed t the staff a lt when it was intrduced in January. It spread like wildfire that smene frm France was here t train the technlgists," Ms. L'Ecuyer said. She added that she had a line f staff at her dr wanting t take the training.
51．One f the results prduced by the trial prject is ________ .
A．a better understanding f children
B．less use f certain medicines
C．new medical-imaging technlgy
D．an imprved reputatin f the hspital
52．The French technlgist came t the children's hspital t ________.
A．assist in treating a patient
B．carry ut hypnsis training
C．start up a new department
D．learn abut the prcedure

A．creating a perfect wrld fr patients
B．frcing patients int a state f deep sleep
C．putting patients int an uncnscius state
D．leading patients' cnsciusness away frm reality
54．What can we learn abut the stry used in the prcedure?
A．It shuld keep pace with the prcedure.
B．It reflects the patient's creativity.
C．It is selected by the technlgist.
D．It tells what dctrs are ding t the patient.
55．The prcedure was received amng the staff with ________.
A．uncertainty
B．enthusiasm
C．wrry
D．criticism
56．What is the passage mainly abut?

本文是说明文。文章说明了杂货店排队方式以及研究人员提出的蛇形队伍的新方式，并分析了各自的利弊。
1．下文“It turns ut, it's just math wrking against yu; chances are, the ther line really is faster. （原来，这只是你的数学问题；很可能，另一个队伍真的更快。）”解释了上文“Yu chse wrng.(你选错了)”的原因，下文与空格处是因果关系，所以本空应该是对前文选错提出疑惑，故选A项。
2．上文“Grcery stres try t have enugh emplyees at checkut t get all their custmers thrugh with minimum delay.（杂货店尽量让足够的员工在结账时让所有的顾客以最小的延误完成结账。）”解释了杂货店之前的工作模式，下文“Any small interruptin a price check, a chatty custmer -can have dwnstream effects, hlding up an entire line.（任何一个小小的中断，一个价格检查，一个喋喋不休的顾客，都会产生下游效应，拖住整个生产线。）”描述了杂货店的特殊情况，故本空应该填出现特殊情况的原因，故选G项。
3．根据上文“If there are three lines in the stre, delays will happen randmly at different registers. （如果杂货店中有三列队伍，延迟将在不同的队伍中随机发生。）”联系下文“S it's nt just in yur mind: Anther line prbably is mving faster.（所以这不仅仅是在你的脑海里：另一条队伍可能移动得更快。）”可知本空说的是任何一个队伍都有可能出现问题。你的队伍跑得最快的几率只有三分之一。故选D项。
4．根据“上文Researchers have a gd way t deal with this prblem.(我们得知研究人员有一个很好的方法来处理这个问题)”以及下文“This is what they d at mst banks and fast-fd restaurants. With a serpentine line, a lng delay at ne register wn't unfairly punish the peple wh lined up behind it. Instead, it will slw dwn everyne little bit but speed up checkut verall.（这个大多数银行和快餐店都是这样做的。有了一条蜿蜒的队伍，在一个登记处长时间拖延不会不公平地惩罚后面排队的人。相反，它会减慢每个人一点点，但加快了整体结帐速度。）”说明这个新方案迅速有效，联系上下文可知，空格中应该是与旧的结账方案作比较。故选F项。
5．结合下文“It takes many registers t keep ne line mving quickly, and sme stres can't affrd the space r manpwer.（要保持一条生产线的快速运转，需要很多的收银机，而且有些商店负担不起空间和人力。）”说明了一个原因，由此可知，空格处提出了一个问题；通过“It takes many registers t keep ne line mving quickly.(保持一条生产线的快速运转)”可知这里描述的是不鼓励蛇形队伍的原因。故选B项。

The decline is nt because we have all becme lazy. Families are pressed fr time, many with bth parents wrking t pay fr their huse, ften wrking hurs nt f their chsing, living in car-dependent neighbrhds with limited public transprt.
The ther side f the cin is equally a deprivatin: fr health and well-being, as well as lst pprtunities（机会）fr children t get t knw their lcal surrundings. And fr parents there are lst pprtunities t walk and talk with their yung schlar abut their day.
Mst parents will have eagerly asked their child abut their day, nly t meet with a “gd”, quickly fllwed by "I'm hungry". This is als my experience as a mther.

11.（2021年1月浙江卷）Researchers say they have translated the meaning f gestures that wild chimpanzees (黑猩猩) use t cmmunicate. They say wild chimps cmmunicate 19 specific messages t ne anther with a "vcabulary" f 66 gestures. The scientists discvered this by fllwing and filming grups f chimps in Uganda, and examining mre than 5,000 incidents f these meaningful exchanges.
Dr Catherine Hbaiter, wh led the research, said that this was the nly frm f intentinal cmmunicatin t be recrded in the animal kingdm. Only humans and chimps, she said, had a system f cmmunicatin where they deliberately sent a message t anther grup member.
"That's what's s amazing abut chimp gestures," she said. "They're the nly thing that lks like human language in that respect. ”
Althugh previus research has shwn that apes and mnkeys can understand cmplex infrmatin frm anther animal's call, the animals d nt appear t use their vices intentinally t cmmunicate messages. This was a significant difference between calls and gestures, Dr Hbaiter said.
Chimps will check t see if they have the attentin f the animal with which they wish t cmmunicate. In ne case, a mther presents her ft t her crying baby, signaling:" Climb n me. " The yungster immediately jumps n t its mthers back and they travel ff tgether. "The big message frm this study is that there is anther species (物种) ut there. that is meaningful in its cmmunicatin, s that's nt unique t humans," said Dr Hbaiter.
Dr Susanne Shultz, an evlutinary bilgist frm the University f Manchester, said the study was praisewrthy in seeking t enrich ur knwledge f the evlutin f human language. But, she added, the results were "a little disappinting".
"The vagueness f the gesture meanings suggests either that the chimps have little t cmmunicate, r we are still missing a lt f the infrmatin cntained in their gestures and actins," she said. "Mrever, the meanings seem t nt g beynd what ther animal cnvey with nn-verbal cmmunicatin. S, it seems the gulf remains. "
44．What d chimps and humans have in cmmn accrding t Dr Hbaiter?
A．Memrizing specific wrds.B．Understanding cmplex infrmatin.
C．Using vices t cmmunicate.D．Cmmunicating messages n purpse.

这是一篇说明文。主要介绍了科学家们通过跟踪和拍摄乌干达的黑猩猩群，翻译出了黑猩猩用来交流的手势含义。
44．细节理解题。根据第二段中的“Only humans and chimps, she said, had a system f cmmunicatin where they deliberately sent a message t anther grup member.（她说，只有人类和黑猩猩有一个交流系统，他们故意向其他成员发送信息）”可知，根据Dr Hbaiter，黑猩猩和人类的共同点在于故意传递信息，故选D。
45．推理判断题。根据第六段中的“Dr Susanne Shultz, an evlutinary bilgist frm the University f Manchester, said the study was praisewrthy in seeking t enrich ur knwledge f the evlutin f human language. But, she added, the results were“a little disappinting”（曼彻斯特大学的进化生物学家苏珊娜·舒尔茨博士说，这项研究是值得称赞的，它试图丰富我们对人类语言进化的知识。但是，她补充说，结果“有点令人失望”）”可知，这项研究是一个好的尝试，但是发现的结果是有限的。故选B。
46．词义猜测题。首先根据第三段中的“They’re the nly thing that lks like human language in that respect.（在这方面，它们是唯一看起来像人类语言的东西）”可知，黑猩猩的手势交流很像我们人类语言的交流方式。但是根据最后一段中的“Mrever, the meanings seem t nt g beynd what ther animals cnvey with nn-verbal cmmunicatins.（此外，这些含义似乎并不超越其他动物通过非语言交流所传达的信息）”可知，黑猩猩手势的交流方式还是和我们语言的交流方式存在不同的，也就是“S, it seems the gulf remains.（所以，看来差异依然存在）”，故gulf的意思是difference，故选A。
47．主旨大意题。根据第一段的“Researchers say they have translated the meaning f gestures that wild chimpanzees use t cmmunicate.（研究人员表示，他们已经翻译出了野生黑猩猩用来交流的手势的含义）”以及文章对这方面的讨论可知，文章主要讲科学家们对黑猩猩手势的研究及一些成果，所以D项：黑猩猩语言：翻译出来的交流手势，这一题目涵盖文章的内容。故选D。

If yu ever get the impressin that yur dg can "tell" whether yu lk cntent r annyed, yu may be nt smething. Dgs may indeed be able t distinguish between happy and angry human faces, accrding t a new study
Researchers trained a grup f 11 dgs t distinguish between images(图像)f the same persn making either a happy r an angry face. During the training stage, each dg was shwn nly the upper half r the lwer half f the persn's face. The researchers then tested the dgs' ability t distinguish between human facial expressins by shwing them the ther half f the persn's face n images ttally different frm the nes used in training. The researchers fund that the dgs were able t pick the angry r happy face by tuching a picture f it with their nses mre ften than ne wuld expect by randm chance.
The study shwed the animals had figured ut hw t apply what they learned abut human faces during training t new faces in the testing stage. "We can rule ut that the dgs simply distinguish between the pictures based n a simple cue, such as the sight f teeth," said study authr Crsin Muller. "Instead, ur results suggest that the successful dgs realized that a smiling muth means the same thing as smiling eyes, and the same rule applies t an angry muth having the same meaning as angry eyes."
"With ur study, we think we can nw cnfidently cnclude that at least sme dgs can distinguish human facial expressins," Muller tld Live Science.
At this pint, it is nt clear why dgs seem t be equipped with the ability t recgnize different facial expressins in humans. "T us, the mst likely explanatin appears t be that the basis lies in their living with humans, which gives them a lt f expsure t human facial expressins," and this expsure has prvided them with many chances t learn t distinguish between them, Muller said.
8. The new study fcused n whether dgs can_________.
A. distinguish shapesB. make sense f human faces
C. feel happy r angryD. cmmunicate with each ther
9. What can we learn abut the study frm paragraph 2?

Returning t a bk yu’ve read many times can feel like drinks with an ld friend. There’s a welcme familiarity - but als smetimes a slight suspicin that time has changed yu bth, and thus the relatinship. But bks dn’t change, peple d. And that’s what makes the act f rereading s rich and transfrmative.
The beauty f rereading lies in the idea that ur bnd with the wrk is based n ur present mental register. It’s true, the lder I get, the mre I feel time has wings. But with reading, it’s all abut the present. It’s abut the nw and what ne cntributes t the nw, because reading is a give and take between authr and reader. Each has t pull their wn weight.
There are three bks I reread annually The first, which I take t reading every spring is Emest Hemningway’s A Mveable Feast. Published in 1964, it’s his classic memir f 1920s Paris. The language is almst intxicating (令人陶醉的)，an aging writer lking back n an ambitius yet simpler time. Anther is Annie Dillard’s Hly the Firm, her petic 1975 ramble (随笔) abut everything and nthing. The third bk is Juli Crtazar’s Save Twilight: Selected Pems, because petry. And because Crtazar.
While I tend t buy a lt f bks, these three were given t me as gifs, which might add t the meaning I attach t them. But I imagine that, while mney is indeed wnderful and necessary, rereading an authr’s wrk is the highest currency a reader can pay them. The best bks are the nes that pen further as time passes. But remember, it’s yu that has t grw and read and reread in rder t better understand yur friends.
24. Why des the authr like rereading?
A. It evaluates the writer-reader relatinship.
B. It’s a windw t a whle new wrld.
C. It’s a substitute fr drinking with a friend.
D. It extends the understanding f neself.
25. What d we knw abut the bk A Mveable Feas!?
A. It’s a brief accunt f a trip.
B. It’s abut Hemingway’s life as a yung man.
C. It’s a recrd f a histric event.
D. It’s abut Hemingway’s friends in Paris.
26. What des the underlined wrd ＂currency＂ in paragraph 4 refer t?
A. Debt
B. Reward.
C Allwance.
D. Face value.
27. What can we infer abut the authr frm the text?
A. He lves petry.
B. He’s an editr.
C. He’s very ambitius.
D. He teaches reading.
【答案】24. D 25. B 26. B 27. A
【解析】这是一篇说明文。短文介绍了重新阅读的意义和益处并向读者介绍了作者每年重读的三本书。作者鼓励读者去重新阅读书籍。
24.推理判断题。根据第一段最后两句“But bks dn’t change, peple d. And that’s what makes the act f rereading s rich and transfrmative.(但是书没变，人变了。那就是使重新阅读行为如此丰富和富于变化之处)”和第二段“The beauty f rereading lies in that ur bnd with the wrk is based n ur present register. It is true, the lder I get, the mre I feel time has wings.(重新阅读的美妙之处在于我们与作品的联系是基于我们现在的心理状态。真的，我年纪越大，就越觉得时光飞逝。)”可推知，作者喜欢重新阅读是因为重新阅读可以扩展对自己的理解。故选D项。
25.推理判断题。根据倒数第二段“Published in 1964, it’s his classic memir f 1920s Paris.”及“an aging writer lking back n an ambitius yet simpler time”可知，这本书出版于1964年，这是他关于20世纪20年代在巴黎的经典回忆录，是他老年时对那些野心勃勃却更简单的日子的回顾。由此可判断出A Mvable Feast是关于海明威年轻时的生活。故选B项。
26.词义猜测题。根据最后一段中“while mney is indeed wnderful and necessary,(虽然金钱确实是美妙而必要的)”可知，前后句为转折关系，根据上下文的语境可推知，“rereading an authr’s wrk is the highest currency a reader can pay them.”意为“但是但重新阅读作品是读者能支付给他们的最高回报”，由此判断出划线词的意思是“回报”。故选B项。
27.推理判断题。根据倒数第二段“The third bk is Juli Crtázar’s Save Twilight: selected pems, because petry.(第三本书是胡里奥·科塔扎的《拯救暮光之城: 诗歌精选》，因为诗歌)”可知，作者是由于喜欢诗歌而喜欢这本书。故选A项。

Race walking shares many fitness benefits with running, research shws, while mst likely cntributing t fewer injuries. It des, hwever, have its wn prblem.
Race walkers are cnditined athletes. The lngest track and field event at the Summer Olympics is the 50-kilmeter race walk, which is abut five miles lnger than the marathn. But the sprt’s rules require that a race walker’s knees stay straight thrugh mst f the leg swing and ne ft remain in cntact (接触) with the grund at all times. It’s this strange frm that makes race walking such an attractive activity, hwever, says Jaclyn Nrberg, an assistant prfessr f exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, Accrding t mst calculatins, race walkers mving at a pace f six miles per hur wuld burn abut 800 calries(卡路里) per hur, which is apprximately twice as many as they wuld burn walking, althugh fewer than running, which wuld prbably burn abut 1,000 r mre calries per hur.
Hwever, race walking des nt pund the bdy as much as running des, Dr. Nrberg says. Accrding t her research, runners hit the grund with as much as fur times their bdy weight per step, while race walkers, wh d nt leave the grund, create nly abut 1.4 times their bdy weight with each step.
As a result, she says, sme f the injuries assciated with running, such as runner’s knee, are uncmmn amng race walkers. But the sprt’s strange frm des place cnsiderable stress n the ankles and hips, s peple with a histry f such injuries might want t be cautius in adpting the sprt. In fact, anyne wishing t try race walking shuld prbably first cnsult a cach r experienced racer t learn prper technique, she says. It takes sme practice.
28. Why are race walkers cnditined athletes?
A. They must run lng distances.
B. They are qualified fr the marathn.
C. They have t fllw special rules.
D. They are gd at swinging their legs.
29. What advantage des race walking have ver running?
A. It’s mre ppular at the Olympics.
B. It’s less challenging physically.
C. It’s mre effective in bdy building.
D. It’s less likely t cause knee injuries.
30. What is Dr. Nrberg’s suggestin fr smene trying race walking?
A. Getting experts’ pinins.
B. Having a medical checkup.
C. Hiring an experienced cach.
D. Ding regular exercises.
31. Which wrd best describes the authr’s attitude t race walking?
A. Skeptical.B. Objective.
C. Tlerant.D. Cnservative.
【答案】28. C 29. D 30. A 31. B
【解析】这是一篇说明文。短文介绍了竞走相比跑步有诸多的优势，但是之前受过伤的人，要想从事这样运动要谨慎，最好咨询专家的建议。
28.细节理解题。根据第二段“But the sprt’s rules require that a race walker’s knees stay straight thrugh mst f the leg swing and ne ft remain in cntact with the grund at all times.”可知，但这项运动的规则要求竞走者的膝盖在摆动腿的大部分时间保持伸直，一只脚始终与地面接触。由此可知，竞走运动员是需要具备某些条件的运动员是因为运动员需要遵守特殊的规则。故选C项。
29.细节理解题。根据最后一段“As a result, she says, sme f the injuries assciated with running, such as runner’s knee, are uncmmn amng race walkers.”可知，一些与跑步有关的损伤，比如跑步者的膝盖，在竞走者中并不常见。由此可知，竞走与跑步相比的优势是不太可能导致膝盖受伤。故选D项。
30.细节理解题。根据最后一段Dr. Nrberg说的话“In fact, anyne wishing t try race walking shuld prbably first cnsult a cach r experienced racer t learn prper technique(事实上，任何想尝试竞走的人都应该首先咨询教练或有经验的竞走运动员，学习适当的技巧。)”可知，Dr. Nrberg建议想尝试竞走的人征询专家的建议。故选A项。
31.推理判断题。根据第一段“Race walking shares many fitness benefits with running, research shws, while mst likely cntributing t fewer injuries. It des, hwever, have its wn prblem.”可知，研究表明，竞走和跑步一样有很多健身益处，而且它还很少导致受伤。不过，它也有自己的问题。由此判断出作者对于竞走的态度是客观的。故选B项。

The cnnectin between peple and plants has lng been the subject f scientific research. Recent studies have fund psitive effects. A study cnducted in Yungstwn，Ohi，fr example, discvered that greener areas f the city experienced less crime. In anther，emplyees were shwn t be 15% mre prductive when their wrkplaces were decrated with huseplants.
The engineers at the Massachusetts Institute f Technlgy(MIT)have taken it a step further changing the actual cmpsitin f plants in rder t get them t perfrm diverse，even unusual functins. These include plants that have sensrs printed nt their leaves t shw when they’re shrt f water and a plant that can detect harmful chemicals in grundwater. ＂We’re thinking abut hw we can engineer plants t replace functins f the things that we use every day,＂explained Michael Stran, a prfessr f chemical engineering at MIT.
One f his latest prjects has been t make plants grw(发光)in experiments using sme cmmn vegetables. Stran’s team fund that they culd create a faint light fr three-and-a-half hurs. The light，abut ne-thusandth f the amunt needed t read by，is just a start. The technlgy, Stran said, culd ne day be used t light the rms r even t turn tree int self-pwered street lamps.
in the future，the team hpes t develp a versin f the technlgy that can be sprayed nt plant leaves in a ne-ff treatment that wuld last the plant’s lifetime. The engineers are als trying t develp an n and ff＂switch＂where the glw wuld fade when expsed t daylight.
Lighting accunts fr abut 7% f the ttal electricity cnsumed in the US. Since lighting is ften far remved frm the pwer surce(电源)-such as the distance frm a pwer plant t street lamps n a remte highway-a lt f energy is lst during transmissin(传输).
Glwing plants culd reduce this distance and therefre help save energy.

When yu were trying t figure ut what t buy fr the envirnmentalist n yur hliday list, fur prbably didn’t crss yur mind. But sme eclgists and fashin (时装)enthusiasts are trying t bring back the market fr fur made frm nutria(海狸鼠).
Unusual fashin shws in New Orleans and Brklyn have(shwcased)nutria fur made int clthes in different styles. “It sunds crazy t talk abut guilt-free fur-unless yu understand that the nutria are destrying vast wetlands every year”, says Cree McCree, prject directr f Righteus Fur.
Scientists in Luisiana were s cncerned that they decided t pay hunters $5 a tail. Sme f the fur ends up in the fashin shws like the ne in Brklyn last mnth.
Nutria were brught there frm Argentina by fur farmers and let g int the wild. “The ecsystem dwn there can’t handle this nn-native species(物种).It’s destrying the envirnment. It’s them r us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria check fr decades，but when the market fr nutria cllapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Bilgist Edmnd Mutn runs the nutria cntrl prgram fr Luisiana. He says it’s nt easy t cnvince peple that nutria fur is green, but he has n dubt abut it. Hunters bring in mre than 300,000 nutria tails a year, s part f Mutn’s jb these days is trying t prmte fur.
Then there’s Righteus Fur and its unusual fashin. Mrgan says，”T give peple a guilt-free ptin that they can wear withut smene thrwing paint n them-1 think that’s ging t be a massive thing, at least here in New Yrk.” Designer Jennifer Andersn admits it tk her a while t cme arund t the pinin that using nutria fur fr her creatins is mrally acceptable. She trying t cme up with a lable t attach t nutria fashins t shw it is ec-friendly.
28. What is the purpse f the fashin shws in New Orleans and Brklyn?
A. T prmte guilt-free fur.
B. T expand the fashin market.
C. T intrduce a new brand.
D. T celebrate a winter hliday.
29. Why are scientists cncerned abut nutria?
A. Nutria damage the ecsystem seriusly.
B. Nutria are an endangered species.
C. Nutria hurt lcal cat-sized animals.
D. Nutria are illegally hunted.
30. What des the underlined wrd “cllapsed” in paragraph 5 prbably mean?
A. Bmed.B. Became mature.C. Remained stable.D. Crashed.
31. What can we infer abuf wearing fur in New Yrk accrding t Mrgan?
A. It’s frmal.B. It’s risky.C. It’s harmful.D. It’s traditinal.
【答案】28. A 29. A 30. D 31. B
【解析】本文是说明文。介绍了美国新奥良和布鲁克林举办了不同寻常的时装秀。展出海狸鼠制成的皮衣。海狸鼠们每年都在破坏大片的湿地，因此设计师称这是一种环保的举措，科学家们也对海狸鼠损坏生态平衡表示了担忧。
28.推理判断题。根据第二段Unusual fashin shws in New Orleans and Brklyn have shwcased nutria fur made int clthes in different styles. “It sunds crazy t talk abut guilt-free fur-unless yu understand that the nutria are destrying vast wetlands every year,”says Cree McCree, prject directr f Righteus Fur.得知，美国新奥尔良和布鲁克林举办了不同寻常的时装秀，时装秀上展出海狸鼠皮制成的不同风格的衣服，项目总监Cree McCree说：“除非了解海狸鼠正每年破坏大片湿地，否则谈论无罪感皮衣是很疯狂的事情”，可以判断出由于海狸鼠对生态造成了巨大的破坏，这场海狸鼠皮衣时装秀销售的是无罪恶感皮衣。故选A。
29.推理判断题。根据第三段Scientists in Luisiana were s cncerned that they decided t pay hunters $5 a tail.得知，科学家们如此担心以至于他们决定按照一条海狸鼠尾巴付给猎人们5美元，可以推断出科学家们担忧海狸鼠们严重破坏生态平衡，。故选A。
30.词义猜测题。根据第五段The fur trade kept nutria in check fr decades, but when the market fr nutria cllapsed in the late 1980s,the cat-sized animals multiplied like crazy. 得知，毛皮贸易使海狸鼠受到了几十年的控制，但是当海狸鼠市场在20世纪80年代末崩溃时，这种猫大小的动物数量疯长，根据but判断，这是转折关系，以前由于皮毛交易，海狸鼠处于控制，现在这种海狸鼠之所以能够数量激增，是由于市场不再销售海狸鼠皮毛导致的，可以推断出划线词cllapsed 是和D.crashed倒闭的意思最相近。故选D。
31.推理判断题。根据第二段Mdel Paige Mrgan says, “T give peple a guilt –free ptin that they can wear withut smene thrwing paint n them-I think that’s ging t be a massive thing, at least in New Yrk. ” 得知，为了给人们一种无罪的选择，人们可以穿皮衣而不被人们泼油漆，我认为在纽约将是一件巨大的事情，根据模特摩根所说得知，在纽约穿皮质衣服是有风险的。故选B。

We are the prducts f evlutin, and nt just evlutin that ccurred billins f years ag. As scientists lk deeper int ur genes (基因), they are finding examples f human evlutin in just the past few thusand years. Peple in Ethipian highlands have adapted t living at high altitudes. Cattle -raising peple in East Africa and nrthern Eurpe have gained a mutatin (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team f researchers reprted a new kind f adaptatin - nt t air r t fd, but t the cean. A grup f sea-dwelling peple in Sutheast Asia have evlved int better divers. The Bajau, as these peple are knwn, number in the hundreds f thusands in Indnesia, Malaysia and the Philippines. They have traditinally lived n husebats; in recent times, they’ve als built huses n stilts (支柱) in castal waters. “They are simply a stranger t the land,” said Redney C. Jubilad, a University f Hawaii researcher wh studies the Bajau.
Dr. Jubilad first met the Bajau while grwing up n Samal Island in the Philippines. They made a living as divers, spearfishing r harvesting shellfish. “We were s amazed that they culd stay underwater much lnger than us lcal islanders,” Dr. Jubilad said. “I culd see them actually walking under the sea.”
In201, Melissa Ilard, then a graduate student in genetics at the University f Cpenhagen, heard abut the Bajau. She wndered if centuries f diving culd have led t the evlutin f physical characteristics that made the task easier fr them. “it seemed like the perfect chance fr natural selectin t act n a ppulatin,” said Dr. Ilard. She als said there were likely a number f ther genes that help the Bajau dive.

Smetimes it’s hard t let g. Fr many British peple, that can apply t institutins and bjects that represent their cuntry’s past-age-ld castles, splendid hmes… and red phne bxes.
Beaten first by the march f technlgy and lately by the terrible weather in junkyards (废品场), the phne bxes representative f an age are nw making smething f a cmeback. Adapted in imaginative ways, many have reappeared n city streets and village greens husing tiny cafes, cellphne repair shps r even defibrillatr machines (除颤器).
The riginal irn bxes with the rund rfs first appeared in 1926. They were designed by Giles Gilbert Sctt, the architect f the Battersea Pwer Statin in Lndn. After becming an imprtant part f many British streets, the phne bxes began disappearing in the 1980s, with the rise f the mbile phne sending mst f them away t the junkyards.
Abut that time, Tny Inglis’ engineering and transprt cmpany gt the jb t remve phne bxes frm the streets and sell them ut. But Inglis ended up buying hundreds f them himself, with the idea f repairing and selling them. He said that he had heard the calls t preserve the bxes and had seen hw sme f them were listed as histric buildings.

Fr thse wh can stmach it, wrking ut befre breakfast may be mre beneficial fr health than eating first, accrding t a study f meal timing and physical activity.
Athletes and scientists have lng knwn that meal timing affects perfrmance. Hwever far less has been knwn abut hw meal timing and exercise might affect general health.
T find ut, British scientists cnducted a study. They first fund 10 verweight and inactive but therwise healthy yung men, whse lifestyles are, fr better and wrse, representative f thse f mst f us. They tested the men’s fitness and resting metablic (新陈代谢的) rates and tk samples (样品) f their bld and fat tissue.
Then, n tw separate mrning visits t the scientists’ lab, each man walked fr an hur at an average speed that, in thery shuld allw his bdy t rely mainly n fat fr fuel. Befre ne f these wrkuts, the men skipped breakfast, meaning that they exercised n a cmpletely empty stmach after a lng vernight fast (禁食). On the ther ccasin, they ate a rich mrning meal abut tw hurs befre they started walking.
Just befre and an hur after each wrkut, the scientists tk additinal samples f the men’s bld and fat tissue.
Then they cmpared the samples. There were cnsiderable differences. Mst bviusly, the men displayed lwer bld sugar levels at the start f their wrkuts when they had skipped breakfast than when they had eaten. As a result, they burned mre fat during walks n an empty stmach than when they had eaten first. On the ther hand, they burned slightly mre calries (卡路里), n average, during the wrkut after breakfast than after fasting.
But it was the effects deep within the fat cells that may have been the mst significant, the researchers fund. Multiple genes behaved differently, depending n whether smene had eaten r nt befre walking. Many f these genes prduce prteins (蛋白质) that can imprve bld sugar regulatin and insulin (胰岛素) levels thrughut the bdy and s are assciated with imprved metablic health. These genes were much mre active when the men had fasted befre exercise than when they had breakfasted.
The implicatin f these results is that t gain the greatest health benefits frm exercise, it may be wise t skip eating first.
61. The underlined expressin “stmach it” in Paragraph 1 mst prbably means “______”.
A. digest the meal easilyB. manage withut breakfast
C. decide wisely what t eatD. eat whatever is ffered
62. Why were the 10 peple chsen fr the experiment?
A. Their lifestyles were typical f rdinary peple.
B. Their lack f exercise led t verweight.
C. They culd walk at an average speed.
D. They had slw metablic rates.
63. What happened t thse wh ate breakfast befre exercise?
A. They successfully lst weight.
B. They cnsumed a bit mre calries.
C. They burned mre fat n average.
D. They displayed higher insulin levels.
64. What culd be learned frm the research?
A. A wrkut after breakfast imprves gene perfrmances.
B. T much wrkut ften slws metablic rates.
C. Lifestyle is nt as imprtant as mrning exercise.
D. Physical exercise befre breakfast is better fr health.
【答案】61. B 62. A 63. B 64. D
【解析】本文是说明文。文章介绍了一项研究，结果表明对于那些能忍受的人来说，不吃早餐锻炼可能对健康更有益。
61.词句猜测题。根据下文wrking ut befre breakfast may be mre beneficial fr health than eating first可知，早餐前锻炼可能比先吃饭再锻炼对健康更有益，因此推断这里说的是那些不吃早饭先锻炼的人，因此推断划线词与B项“不吃早饭能应付”意思相近。故选B。
62.细节理解题。根据第三段的They first fund 10 verweight and inactive but therwise healthy yung men, whse lifestyles are far better and wrse, representative f thse f mst f us.可知，他们首先找到了10个超重的，不活跃但健康的年轻人，他们的生活方式可以说更好，也可以说更糟，代表了我们大多数人。因此可知，实验时选择的10个人的生活方式代表了普通人。故选A。
63.细节理解题。根据第六段的As a result, they burned mre fat during walks n an empty stmach than when they had eaten first. On the ther hand. they burned slightly mre calries(卡路里), n average, during the wrkut after breakfast than after fasting.可知，结果，他们空腹散步时燃烧的脂肪比他们首先吃东西时所燃烧的脂肪要多。 另一方面。平均而言，他们在早餐后锻炼时燃烧的卡路里略多于禁食后。因此可知，锻炼前吃早饭消耗更多一点的热量。故选B。
64.推理判断题。根据最后一段The implicatin f these results is that t gain the greatest health benefits frm exercise, it may be wise t skip eating first.可知，这些结果的暗示，为了从运动中获得最大的健康益处，先不吃东西可能更明智。因此推断早饭前的体育锻炼对健康更有益。故选D。

Accrding t a recent study in the Jurnal f Cnsumer Research, bth the size and cnsumptin habits f ur eating cmpanins can influence ur fd intake. And cntrary t existing research that says yu shuld avid eating with heavier peple wh rder large prtins(份), it's the beanples with big appetites yu really need t avid.
T test the effect f scial influence n eating habits the researchers cnducted tw experiments. In the first, 95 undergraduate wmen were individually invited int a lab t stensibly(表面上)participate in a study abut mvie viewership. Befre the film began, each wman was asked t help herself t a snack. An actr hired by the researchers grabbed her fd first. In her natural state, the actr weighed 105 punds. But in half the cases she wre a specially designed fat suit which increased her weight t 180 punds.
Bth the fat and thin versins f the actr tk a large amunt f fd. The participants fllwed suit, taking mre fd than they nrmally wuld have. Hwever, they tk significantly mre when the actr was thin.
Fr the secnd test, in ne case the thin actr tk tw pieces f candy frm the snack bwls. In the ther case, she tk 30 pieces. The results were similar t the first test: the participants fllwed suit but tk significantly mre candy when the thin actr tk 30 pieces.
The tests shw that the scial envirnment is extremely influential when we're making decisins. If this fellw participant is ging t eat mre, s will I. Call it the “I’ll have what she's having” effect. Hwever, we'll adjust the influence. If an verweight persn is having a large prtin, I'll hld back a bit because I see the results f his eating habits. But if a thin persn eats a lt, I'll fllw suit. If he can eat much and keep slim, why can't I?
12. What is the recent study mainly abut?
A. Fd safety.B. Mvie viewership.
C. Cnsumer demand.D. Eating behavir.
13. What des the underlined wrd “beanples” in paragraph 1 refer t?
A. Big eaters.B. Overweight persns.
C. Picky eaters.D. Tall thin persns.
14. Why did the researchers hire the actr?
A. T see hw she wuld affect the participants.
B. T test if the participants culd recgnize her.
C. T find ut what she wuld d in the tw tests.
D. T study why she culd keep her weight dwn.
15. On what basis d we “adjust the influence” accrding t the last paragraph?
A. Hw hungry we are.B. Hw slim we want t be.
C. Hw we perceive thers.D. Hw we feel abut the fd.
【答案】12. D 13. D 14. A 15. C
【解析】本文是说明文。最近的研究表明：我们的饮食伙伴的大小和消费习惯都会影响我们的食物摄入量。文章详述了这个实验的过程。
12.细节理解题。根据第一段中的“Accrding t a recent study in the Jurnal f Cnsumer Research, bth the size and cnsumptin habits f ur eating cmpanins can influence ur fd intake”可知，根据消费者研究杂志最近的一项研究，我们的饮食伙伴的大小和消费习惯都会影响我们的食物摄入量。因此这项研究是关于饮食行为的。故选D。
13.词义猜测题。根据前半句“And cntrary t existing research that says yu shuld avid eating with heavier peple wh rder large prtins（份）”可知，现有的研究认为：你应该避免和体重较重、点大份饭菜的人一起吃饭。后半句认为，你真正应该避免的是the beanples with big appetites。由cntrary t可推断出，画线词和heavier peple（超重的人）相反，结合选项，D选项（瘦瘦高高的人）正好和heavier peple正好相反。故选D。
14.推理判断题。根据第二段的“T test the effect f scial influence n eating habits, the researchers cnducted tw experiments”可知， 为了测试社会影响对饮食习惯的影响，研究人员进行了两个实验。根据倒数第三段的内容可知，在两个实验中，胖的和瘦的演员都吃了大量的食物。参与者也照做，吃的食物比平常多。 然而，当演员是瘦的时候，参与者们服用的食物更多。由此推断，研究人员雇用演员是为了看看她如何影响参与者。故选A。
15.推理判断题。根据最后一段中的“If an verweight persn is having a large prtin, I’ll hld back a bit because I see the results f his eating habits. But if a thin persn eats a lt, I’ll fllw suit. If he can eat much and keep slim, why can’t I? ”可知，如果一个超重的人吃很大一份，我会忍住一点，因为我看到了他饮食习惯的结果。但如果一个瘦的人吃很多，我会跟着做。如果他吃得多保持苗条，为什么我不能呢？ 因此推断我们是根据我们对他人的看法（即：如何看待他人）来调整影响的。故选C。

Fr peple, wh are interested in sund, the field f sund technlgy is definitely making nise. In the past, sund engineers wrked in the back rms f recrding studis, but many f tday’s sund prfessinals are sharing their knwledge and experience with prfessinals in ther fields t create new prducts based n the phenmenn we call sund.
Sund can be used as a weapn. Imagine that a plice fficer is chasing a thief. The thief tries t escape. And the fficer can’t let him get away. He pulls ut a special device, pints it at the suspect, and switches it n. The thief drps t the grund. This new weapn is called a Lng Range Acustic Device(LRAD, 远程定向声波发射器). It prduces a deafening sund s painful that it temprarily disables a persn. The nise frm the LRAD is directed like a ray f light and travels nly int the ears f that persn, but it is nt deadly.
Fr thse wh hunger fr sme peace and quiet, sund can nw create silence. Let’s say yu are at the airprt, and the little by n the seat next t yu is humming(哼唱) a shrt cmmercial sng.

Simply turn the machine r pint it at the target, and yur peace and quiet cmes back.
Directed sund is a new technlgy that allws cmpanies t use sund in much the same way sptlights(聚光灯) are used in the theater. A sptlight lights up nly ne sectin f a stage; similarly, “sptsund” creates a circle f sund in n targeted area. This can be useful fr businesses such as restaurants and stres because it ffers a new way t attract custmers. Restaurants can ffer a chice f music alng with the varius fd chices n the menu, allwing custmers mre cntrl ver the atmsphere in which they are dining. Directed sund is als beginning t appear in shpping centers and even at hmes.

The nise frm the LRAD is directed like a ray f light and travels nly int the ears f that persn, but it is nt deadly.”可知它发出震耳欲聋的声音，这种声音令人如此痛苦以至于它会使人暂时丧失能力。LRAD发出的噪音像光线一样被引导，只进入那个人的耳朵，但不会致命。由此可推知，LRAD会导致暂时性听力损失。故选A。
47.细节理解题。根据第三段中的“Well, it functins by analyzing the waves f the incming sund and creating a secnd set f utging waves. The tw sets f waves cancel each ther ut. Simply turn the machine n pint it at the target, and yur peace and quiet cmes back.”可知，它的功能是通过分析传入声音的波，并产生第二组传出的波。这两组波会相互抵消。只要打开机器对准目标，你的宁静就会回来。由此可知，静音机是一种专门设计用来阻止有害声音影响你的设备。故选D。
48.细节理解题。根据最后一段中的“A sptlight lights up nly ne sectin f a stage; similarly, a “sptsund” creates a circle f sund in ne targeted area.”可知，聚光灯只能照亮舞台的一个部分；类似地，一个“sptsund”在一个目标区域创建一个声音圈。由此可知，sptsunds和聚光灯的共同特性是它们可以被定向到一个特定的区域，故选D。
49.细节理解题。根据最后一段中的“A sptlight lights up nly ne sectin f a stage; similarly,”sptsund” creates a circle f sund in n targeted area.

The traffic signals alng Factria Bulevard in Bellevue, Washingtn, generally dn't flash the same length f green twice in a rw, especially at rush hur. At 9:30am, the full red/yellw/green signal cycle might be 140 secnds. By 9:33am, a burst f additinal traffic might push it t 145 secnds. Less traffic at 9:37am culd push it dwn t 135. Just like the traffic itself, the timing f the signals changes.
That is by design. Bellevue, a fast-grwing city just east f Seattle, uses a system that is gaining ppularity arund the US: intersectin(十字路口) signals that can adjust in real time t traffic cnditins. These lights, knwn as adaptive signals, have led t significant declines in bth the truble and cst f travels between wrk and hme.
“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanvic, a researcher at Flrida Atlantic University.
Fr all f Bellevue’s success, adaptive signals are nt a cure-all fr jammed radways. Kevin Balke, a research engineer at the Texas A&M University Transprtatin Institute, says that while smart lights can be particularly beneficial fr sme cities, thers are s jammed that nly a sharp reductin in the number f cars n the rad will make a meaningful difference. “It’s nt ging t fix everything, but adaptive signals have sme benefits fr smaller cities,” he says.
In Bellevue, the switch t adaptive signals has been a lessn in the value f welcming new appraches. In the past, there was ften an autmatic reactin t increased traffic: just widen the rads, says Mark Pch, the Bellevue Transprtatin Department’s traffic engineering manager. Nw he hpes that ther cities will cnsider making their streets run smarter instead f just making them bigger.
25. What des the underlined wrd “that” in paragraph 2 refer t?
A. Increased length f green lights.B. Shrtened traffic signal cycle.
C. Flexible timing f traffic signals.D. Smth traffic flw n the rad.
26. What des Kevin Balke say abut adaptive signals?
A. They wrk better n brad rads.
B. They shuld be used in ther cities.
C. They have greatly reduced traffic n the rad.
D. They are less helpful in cities seriusly jammed.
27. What can we learn frm Bellevue’s success?
A. It is rewarding t try new things.B. The ld methds still wrk tday.
C. I pays t put thery int practice.D. The simplest way is the best way.

【解析】这是一篇说明文。美国华盛顿州的Bellevue采用了能随交通状况而调节交通灯时间的适应性信号灯，大大缓解了交通压力，也表明人们对于交通阻塞问题不再只是拓宽道路，而是能够采用新方法。
25.指代猜测题。That位于第二段句首，应是指代第一段的内容。根据第一段内容尤其是第一段最后一句“Just like the traffic itself, the timing f the signals changes.(就像交通本身一样，信号灯的时间也会变化)”可知，第一段主要讲述的是信号灯的时间会灵活变化；“That is by design.”意为“那是有意为之”，由此可推知，That指代第一段中“信号灯的灵活时间”。故选C项。
26.推理判断题。根据第四段第一句中“adaptive signals are nt a cure-all fr jammed radways(但自适应信号并不是解决拥堵道路的万能药)”及第二句中“thers are s jammed that nly a sharp reductin in the number f cars n the rad will make a meaningful difference(其他城市交通堵塞如此严重，只有减少道路上的车辆才能起有意义的作用) ”可推知，Kevin Balke认为适应性信号灯对于交通堵塞很严重的城市没有太大帮助。故选D项。
27.推理判断题。根据第二段最后一句“These lights, knwn as adaptive signals, have led t significant declines in bth the truble and cst f travels between wrk and hme.(这些灯，被称为适应性信号灯，已经大大减少了通勤的麻烦和花费)”最后一段第一句“In Bellevue, the switch t adaptive signals has been a lessn in the value f welcming new appraches.(在Bellevue，对适应性信号灯的转变是一个在欢迎新方法的价值方面的榜样)”可推知，从Bellevue的成功中可以得出，尝试新事物是值得的。故选A项。

Challenging wrk that requires lts f analytical thinking, planning and ther managerial skills might help yur brain stay sharp as yu age, a study published Wednesday in the jurnal Neurlgy suggests.
Researchers frm the University f Leipzig in Germany gathered mre than 1, 000 retired wrkers wh were ver age 75 and assessed the vlunteers’ memry and thinking skills thrugh a battery f tests. Then, fr eight years, the scientists asked the same grup t cme back t the lab every 18 mnths t take the same srts f tests.
Thse wh had held mentally stimulating(刺激), demanding jbs befre retirement tended t d the best n the tests. And they tended t lse cgnitive(认知) functin at a much slwer rate than thse with the least mentally challenging jbs. The results held true even after the scientists accunted fr the participants’ verall health status.
“This wrks just like physical exercise, ” says Francisca Then, wh led the study. “After a lng run, yu may feel like yu’re in pain, yu may feel tired. But it makes yu fit. After a lng day at wrk-sure, yu will feel tired, but it can help yur brain stay healthy. ”
It's nt just crprate jbs, r even paid wrk that can help keep yur brain fit, Then pints ut. A waiter’s jb, fr example, that requires multitasking, teamwrk and decisin-making culd be just as stimulating as any high-level ffice wrk. And “running a family husehld requires high-level planning and crdinating(协调), ” she says. “Yu have t rganize the activities f the children and take care f the bills and grceries. ”
Of curse, ur brains can decline as we grw lder fr lts f reasns-including ther envirnmental influences r genetic factrs. Still, cntinuing t challenge yurself mentally and keeping yur mind busy can nly help.
28. Why did the scientists ask the vlunteers t take the tests?

Befre the 1830smst newspapers were sld thrugh annual subscriptins in America, usually $8 t $10 a year. Tday $8 r $10 seems a small amunt f mney, but at that time these amunts were frbidding t mst citizens. Accrdingly, newspapers were read almst nly by rich peple in plitics r the trades. In additin, mst newspapers had little in them that wuld appeal t a mass audience. They were dull and visually frbidding. But the revlutin that was taking place in the 1830s wuld change all that.
The trend, then, was tward the "penny paper"-a term referring t papers made widely available t the public. It meant any inexpensive newspaper; perhaps mre imprtantly it meant newspapers that culd be bught in single cpies n the street.
This develpment did nt take place vernight. It had been pssible(but nt easy)t buy single cpies f newspapers befre 1830,but this usually meant the reader had t g dwn t the printer's ffice t purchase a cpy. Street sales were almst unknwn.

Mnkeys seem t have a way with numbers.
A team f researchers trained three Rhesus mnkeys t assciate 26 clearly different symbls cnsisting f numbers and selective letters with 0-25 drps f water r juice as a reward. The researchers then tested hw the mnkeys cmbined—r added—the symbls t get the reward.
Here's hw Harvard Medical Schl scientist Margaret Livingstne, wh led the team, described the experiment: In their cages the mnkeys were prvided with tuch screens. On ne part f the screen, a symbl wuld appear, and n the ther side tw symbls inside a circle were shwn. Fr example, the number 7 wuld flash n ne side f the screen and the ther end wuld have 9 and 8. If the mnkeys tuched the left side f the screen they wuld be rewarded with seven drps f water r juice; if they went fr the circle, they wuld be rewarded with the sum f the numbers—17 in this example.
After running hundreds f tests, the researchers nted that the mnkeys wuld g fr the higher values mre than half the time, indicating that they were perfrming a calculatin, nt just memrizing the value f each cmbinatin.
When the team examined the results f the experiment mre clsely, they nticed that the mnkeys tended t underestimate(低估)a sum cmpared with a single symbl when the tw were clse in value—smetimes chsing, fr example, a 13 ver the sum f 8 and 6. The underestimatin was systematic: When adding tw numbers, the mnkeys always paid attentin t the larger f the tw, and then added nly a fractin(小部分)f the smaller number t it.
"This indicates that there is a certain way quantity is represented in their brains, "Dr. Livingstne says. “But in this experiment what they're ding is paying mre attentin t the big number than the little ne.”

By next year，half f the calls we receive will be scams(欺诈).We are finally waking up t the severity f the prblem by supprting and develping a grup f tls，apps and appraches intended t prevent scammers frm getting thrugh. Unfrtunately，it's t little，t late. By the time these “slutins"(解决方案)becme widely available，scammers will have mved nt cleverer means. In the near future，it's nt just ging t be the number yu see n yur screen that will be in dubt. Sn yu will als questin whether the vice yu're hearing is actually real.

【语篇解读】这是一篇说明文。语音操作与自动化技术的出现使得机器人电话可以以假乱真。语音操作和自动化技术发展会使得机器人电话产生的问题更加严重。
38. D 【解析】观点态度题。根据第一段中的“We are finally waking up t the severity f the prblem by supprting and develping a grup f tls, apps and appraches intended t prevent scammers frm getting thrugh. Unfrtunately, it’s t little, t late. By the time these “slutins” becme widely available, scammers will have mved nt clever means”可知，最后，我们通过支持和开发一组旨在防止欺诈者通过的工具、应用程序和方法，认识到了问题的严重性。不幸的是，我们的努力太少了，也太晚了。在这些“解决方案”被广泛使用的时候，骗子将转移到更巧妙的手段上。由此推知，作者认为这些“解决办法”对于解决问题起不了什么作用，因此作者感到很“失望”。故D选项正确。
39.A 【解析】细节理解题。根据第三段中的“The reasn that rbcalls are a headache has less t d with amunt than precisin.

By the end f the century，if nt sner，the wrld's ceans will be bluer and greener thanks t a warming climate，accrding t a new study.
At the heart f the phenmenn lie tiny marine micrrganisms(海洋微生物)called phytplanktn. Because f the way light reflects ff the rganisms，these phytplanktn create clurful patterns at the cean surface. Ocean clur varies frm green t blue，depending n the type and cncentratin f phytplanktn. Climate change will fuel the grwth f phytplanktn in sme areas，while reducing it in ther spts，leading t changes in the cean's appearance.
Phytplanktn live at the cean surface，where they pull carbn dixide(二氧化碳)int the cean while giving ff xygen. When these rganisms die，they bury carbn in the deep cean，an imprtant prcess that helps t regulate the glbal climate. But phytplanktn are vulnerable t the cean's warming trend. Warming changes key characteristics f the cean and can affect phytplanktn grwth，since they need nt nly sunlight and carbn dixide t grw，but als nutrients.
Stephanie Dutkiewicz，a scientist in MIT's Center fr Glbal Change Science，built a climate mdel that prjects changes t the ceans thrughut the century. In a wrld that warms up by 3℃，it fund that multiple changes t the clur f the ceans wuld ccur. The mdel prjects that currently blue areas with little phytplanktn culd becme even bluer. But in sme waters，such as thse f the Arctic，a warming will make cnditins riper fr phytplanktn，and these areas will turn greener. “Nt nly are the quantities f phytplanktn in the cean changing. ”she said，“but the type f phytplanktn is changing. ”
42. What are the first tw paragraphs mainly abut?
A. The varius patterns at the cean surface.
B. The cause f the changes in cean clur.
C. The way light reflects ff marine rganisms.
D. The effrts t fuel the grwth f phytplanktn.
43. What des the underlined wrd“vulnerable”in Paragraph 3 prbably mean?
A. Sensitive.B. BeneficialC. SignificantD. Unnticeable
44. What can we learn frm the passage?
A. Phytplanktn play a declining rle in the marine ecsystem.
B. Dutkiewicz's mdel aims t prject phytplanktn changes
C. Phytplanktn have been used t cntrl glbal climate
D. Oceans with mre phytplanktn may appear greener.
45. What is the main purpse f the passage？
A. T assess the cnsequences f cean clur changes
B. T analyse the cmpsitin f the cean fd chain
C. T explain the effects f climate change n ceans
D. T intrduce a new methd t study phytplanktn
【语篇解读】本文为说明文。一项最新研究表明，由于气候变暖，世界海洋将会变得更蓝、更绿。这一现象是因为一种叫做浮游植物的微小海洋微生物，因为光线反射的作用，它们在海洋表面形成了五颜六色的图案。但是浮游植物很容易受到海洋变暖趋势的影响。气候变暖会改变海洋的主要特征，并影响浮游植物的生长。
42. B 【解析】段落大意题。第一段“By the end f the century. If nt sner, the wrld's ceans will be bluer and greener thanks t a warming climate, accrding t a new study.”可知，到本世纪末，一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。结合第二段“At the heart phenmenn lie tiny marine micrrganisms called phytplanktn. Becaust f the way light reflects ff the rganisms ,these phytplanktns create clurful patterns at the cean surface. Ocean clur varies frm green t blue, depending n the type and cncentratin”可知，这种现象的核心是一种叫做浮游植物的微小海洋微生物，在光线的作用下在海洋表面形成了五颜六色的图案。海洋的颜色从绿色到蓝色不等，这取决于海洋的类型和浮游植物浓度。由此可推断出这两段主要叙述了海洋生物是海洋颜色变化的原因。分析选项可知B符合题意，故选B。
43. A【解析】词义猜测题。根据划线词后的“Warming changes key characteristics f the cean and can affect phytplanktn grwth, since they need nt nly sunshine and carbn dixide t grw, but als nutrients.”可知，气候变暖会改变海洋的主要特征，并会影响浮游植物的生长。由此可判断“But phytplanktn are vulnerable t the cean’s wamning trend”可知，浮游植物很容易受到海洋变暖趋势的影响。可知A项正确。
44. D 【解析】推理判断题。根据第四段“The mdel prjects that currently blue areas with little phytplanktn culd becme even bluer. But in sme waters ,such as thse f the Arctic, a warming will make cnditins riper fr phytplanktn, and these areas will turn greener”,可知Dutkiewicz的模型预测，目前只有少量浮游植物的蓝色区域可能会变得更蓝。但是在一些水域，比如北极，气候变暖会使浮游植物的生长条件更加成熟，而这些水域会变得更绿了”。由此可推断，浮游植物的生长条件更加成熟，浮游动植物就更多了，这些水域会变得更绿了。分析选项可知D项符合题意。
45. C【解析】目的意图题。第一段提出文章的主旨“By the end f the century. If nt sner, the wrld's ceans will be bluer and greener thanks t a warming climate, accrding t a new study.”可知到本世纪末。一项新的研究表明，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿。再结合第三段“But phytplanktn are vulnerable t the cean’s warning trendWarming changes key characteristics f the cean and can affect phytplanktn grwth, …”可知，“浮游植物很容易受到海洋警告趋势的影响，变暖改变了海洋的关键特征，并能影响浮游植物的生长”。可知本文主要解释气候变化对海洋的影响。故选C。

Hw des an ecsystem（生态系统）wrk？What makes the ppulatins f different species the way they are？Why are there s many flies and s few wlves？T find an answer，scientists have built mathematical mdels f fd webs，nting wh eats whm and hw much each ne eats.
With such mdels，scientists have fund ut sme key principles perating in fd webs. Mst fd webs，fr instance，cnsist f many weak links rather than a few strng nes. When a predatr（掠食动物）always eats huge numbers f a single prey（猎物），the tw species are strngly linked；when a predatr lives n varius species，they are weakly linked. Fd webs may be dminated by many weak links because that arrangement is mre stable ver the lng term. If a predatr can eat several species，it can survive the extinctin（灭绝）f ne f them. And if a predatr can mve n t anther species that is easier t find when a prey species becmes rare，the switch allws the riginal prey t recver. The weak links may thus keep species frm driving ne anther t extinctin.
Mathematical mdels have als revealed that fd webs may be unstable，where small changes f tp predatrs can lead t big effects thrughut entire ecsystems. In the 1960s，scientists prpsed that predatrs at the tp f a fd web had a surprising amunt f cntrl ver the size f ppulatins f ther species---including species they did nt directly attack.
And unplanned human activities have prved the idea f tp-dwn cntrl by tp predatrs t be true. In the cean，we fished fr tp predatrs such as cd n an industrial scale，while n land，we killed ff large predatrs such as wlves. These actins have greatly affected the eclgical balance.
Scientists have built an early-warning system based n mathematical mdels. Ideally，the system wuld tell us when t adapt human activities that are pushing an ecsystem tward a breakdwn r wuld even allw us t pull an ecsystem back frm the brderline. Preventin is key，scientists says because nce ecsystems pass their tipping pint（临界点），it is remarkably difficult fr them t return.

A. The living habits f species in fd webs.
B. The rules gverning fd webs f the ecsystems.
C. The appraches t studying the species in the ecsystems.
D. The differences between weak and strng links in fd webs.
47. A strng link is fund between tw species when a predatr______
A. has a wide fd chice
B. can easily find new prey
C. sticks t ne prey species
D. can quickly mve t anther place
48. What will happen if the ppulatins f tp predatrs in a fd web greatly decline？
A. The prey species they directly attack will die ut.
B. The species they indirectly attack will turn int tp predatrs.
C. The living envirnment f ther species will remain unchanged.
D. The ppulatins f ther species will experience unexpected changes.

In the 1960s，while studying the vlcanic histry f Yellwstne Natinal Park，Bb Christiansen became puzzled abut smething that，ddly，had nt trubled anyne befre:he culdn't find the park's vlcan. It had been knwn fr a lng time that Yellwstne was vlcanic in nature — that's what accunted fr all its ht springs and ther steamy features. But Christiansen culdn't find the Yellwstne vlcan anywhere.
Mst f us，when we talk abut vlcanes，think f the classic cne(圆锥体)shapes f a Fuji r Kilimanjar，which are created when erupting magma(岩浆)piles up. These can frm remarkably quickly. In 1943，a Mexican farmer was surprised t see smke rising frm a small part f his land. In ne week he was the cnfused wner f a cne five hundred feet high. Within tw years it had tpped ut at almst furteen hundred feet and was mre than half a mile acrss. Altgether there are sme ten thusand f these vlcanes n Earth，all but a few hundred f them extinct.

Yellwstne bviusly was f this secnd type，but Christiansen culdn't find the caldera anywhere.
Just at this time NASA decided t test sme new high-altitude cameras by taking phtgraphs f Yellwstne. A thughtful fficial passed n sme f the cpies t the park authrities n the assumptin that they might make a nice blw-up fr ne f the visitrs' centers. As sn as Christiansen saw the phts，he realized why he had failed t spt the caldera; almst the whle park-2.2 millin acres—was caldera. The explsin had left a hle mre than frty miles acrss—much t huge t be seen frm anywhere at grund level. At sme time in the past Yellwstne must have blwn up with a vilence far beynd the scale f anything knwn t humans.

Califrnia has lst half its big trees since the 1930s, accrding t a study t be published Tuesday and climate change seems t be a majr factr(因素).
The number f trees larger than tw feet acrss has declined by 50 percent n mre than 46, 000 square miles f Califrnia frests, the new study finds. N area was spared r unaffected, frm the fggy nrthern cast t the Sierra Nevada Muntains t the San Gabriels abve Ls Angeles. In the Sierra high cuntry, the number f big trees has fallen by mre than 55 percent; in parts f suthern Califrnia the decline was nearly 75 percent.
Many factrs cntributed t the decline, said Patrick Mclntyre, an eclgist wh was the lead authr f the study. Wdcutters targeted big trees. Husing develpment pushed int the wds. Aggressive wildfire cntrl has left Califrnia frests crwded with small trees that cmpete with big trees fr resurces(资源).
But in cmparing a study f Califrnia frests dne in the 1920s and 1930s with anther ne between 2001 and 2010, Mclntyre and his clleagues dcumented a widespread death f big trees that was evident even in wildlands prtected frm wdcutting r develpment.
The lss f big trees was greatest in areas where trees had suffered the greatest water shrtage. The researchers figured ut water stress with a cmputer mdel that calculated hw much water trees were getting in cmparisn with hw much they needed, taking int accunt such things as rainfall, air temperature, dampness f sil, and the timing f snwmelt(融雪).
Since the 1930s, Mclntyre said, the biggest factrs driving up water stress in the state have been rising temperatures, which cause trees t lse mre water t the air, and earlier snwmelt, which reduces the water supply available t trees during the dry seasn.

We may think we’re a culture that gets rid f ur wrn technlgy at the first sight f smething shiny and new, but a new study shws that we keep using ur ld devices (装置) well after they g ut f style. That’s bad news fr the envirnment – and ur wallets – as these utdated devices cnsume much mre energy than the newer nes that d the same things.
T figure ut hw much pwer these devices are using, Callie Babbitt and her clleagues at the Rchester Institute f Technlgy in New Yrk tracked the envirnmental csts fr each prduct thrughut its life – frm when its minerals are mined t when we stp using the device. This methd prvided a readut fr hw hme energy use has evlved since the early 1990s. Devices were gruped by generatin. Desktp cmputers, basic mbile phnes, and bx-set TVs defined 1992. Digital cameras arrived n the scene in 1997. And MP3 players, smart phnes, and LCD TVs entered hmes in 2002, befre tablets and e-readers shwed up in 2007.
As we accumulated mre devices, hwever, we didn’t thrw ut ur ld nes. “The living-rm televisin is replaced and gets planted in the kids’ rm, and suddenly ne day, yu have a TV in every rm f the huse,” said ne researcher.

But nt all cities develp slwly ver a lng perid f time. Bm twns grw frm nthing almst vernight. In 1896, Dawsn, Canada, was unmapped wilderness(荒野). But gld was discvered there in 1897, and tw years later, it was ne f the largest cities in the West, with a ppulatin f 30,000.
Dawsn did nt have any f the natural cnveniences f cities like Lndn r Paris. Peple went there fr gld. They travelled ver snw-cvered muntains and sailed hundreds f miles up icy rivers. The path t Dawsn was cvered with thirty feet f wet snw that culd fall withut warming. An avalanche(雪崩) nce clsed the path, killing 63 peple.

Plastic-Eating Wrms
Humans prduce mre than 300 millin tns f plastic every year. Almst half f that winds up in landfills(垃圾填埋场), and up t 12 millin tns pllute the ceans. S far there is n effective way t get rid f it, but a new study suggests an answer may lie in the stmachs f sme hungry wrms.
Researchers in Spain and England recently fund that the wrms f the greater wax mth can break dwn plyethylene, which accunts fr 40% f plastics. The team left 100 wax wrms n a cmmercial plyethylene shpping bag fr 12 hurs, and the wrms cnsumed and brke dwn abut 92 milligrams, r almst 3% f it. T cnfirm that the wrms’ chewing alne was nt respnsible fr the plyethylene breakdwn, the researchers made sme wrms int paste(糊状物) and applied it t plastic films. 14 hurs later the films had lst 13% f their mass — apparently brken dwn by enzymes (酶) frm the wrms’ stmachs. Their findings were published in Current Bilgy in 2017.
Federica Bertcchini, c-authr f the study, says the wrms’ ability t break dwn their everyday fd — beeswax — als allws them t break dwn plastic. ＂Wax is a cmplex mixture, but the basic bnd in plyethylene, the carbn-carbn bnd, is there as well, ＂she explains, ＂The wax wrm evlved a methd r system t break this bnd. ＂
Jennifer DeBruyn, a micrbilgist at the University f Tennessee, wh was nt invlved in the study, says it is nt surprising that such wrms can break dwn plyethylene. But cmpared with previus studies, she finds the speed f breaking dwn in this ne exciting. The next step, DeBruyn says, will be t identify the cause f the breakdwn. Is it an enzyme prduced by the wrm itself r by its gut micrbes(肠道微生物)?
Bertcchini agrees and hpes her team’s findings might ne day help emply the enzyme t break dwn plastics in landfills. But she expects using the chemical in sme kind f industrial prcess — nt simply ＂millins f wrms thrwn n tp f the plastic. ＂
43. What can we learn abut the wrms in the study?
A. They take plastics as their everyday fd.
B. They are newly evlved creatures.
C. They can cnsume plastics.
D. They wind up in landfills.
44. Accrding t Jennifer DeBruyn, the next step f the study is t .
A. identify ther means f the breakdwn
B. find ut the surce f the enzyme
C. cnfirm the research findings
D. increase the breakdwn speed
45. It can be inferred frm the last paragraph that the chemical might .
A. help t raise wrms
B. help make plastic bags
C. be used t clean the ceans

There’s a new frntier in 3D printing that’s beginning t cme int fcus: fd. Recent develpment has made pssible machines that print, ck, and serve fds n a mass scale. And the industry isn’t stpping there.
Fd prductin
With a 3D printer, a ck can print cmplicated chclate sculptures and beautiful pieces fr decratin n a wedding cake. Nt everybdy can d that — it takes years f experience, but a printer makes it easy. A restaurant in Spain uses a Fdini t “re-create frms and pieces” f fd that are “exactly the same,” freeing cks t cmplete ther tasks. In anther restaurant, all f the dishes and desserts it serves are 3D-printed, rather than farm t table.
Sustainability(可持续性)
The glbal ppulatin is expected t grw t 9.6 billin by 2050, and sme analysts estimate that fd prductin will need t be raised by 50 percent t maintain current levels. Sustainability is becming a necessity. 3D fd printing culd prbably cntribute t the slutin. Sme experts believe printers culd use hydrcllids (水解胶体) frm plentiful renewables like algae(藻类) and grass t replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissins. Grcery stres f the future might stck "fd" that lasts years n end, freeing up shelf space and reducing transprtatin and strage requirements.
Nutritin
Future 3D fd printers culd make prcessed fd healthier. Hd Lipsn, a prfessr at Clumbia University, said, “Fd printing culd allw cnsumers t print fd with custmized nutritinal cntent, like vitamins. S instead f eating a piece f yesterday’s bread frm the supermarket, yu’d eat smething baked just fr yu n demand.”
Challenges
Despite recent advancements in 3D fd printing, the industry has many challenges t vercme. Currently, mst ingredients must be changed t a paste(糊状物) befre a printer can use them, and the printing prcess is quite time-cnsuming, because ingredients interact with each ther in very cmplex ways. On tp f that, mst f the 3D fd printers nw are restricted t dry ingredients, because meat and milk prducts may easily g bad. Sme experts are skeptical abut 3D fd printers, believing they are better suited fr fast fd restaurants than hmes and high-end restaurants.
46. What benefit des 3D printing bring t fd prductin?
A. It helps cks t create new dishes.
B. It saves time and effrt in cking.
C. It imprves the cking cnditins.
D. It cntributes t restaurant decratins.
47. What can we learn abut 3D fd printing frm Paragraphs 3?
A. It slves fd shrtages easily.
B. It quickens the transprtatin f fd.
C. It needs n space fr the strage f fd.
D. It uses renewable materials as surces f fd.
48. Accrding t Paragraph 4, 3D-printed fd _____________.
A. is mre available t cnsumers
B. can meet individual nutritinal needs
C. is mre tasty than fd in supermarkets
D. can keep all the nutritin in raw materials
49. What is the main factr that prevents 3D fd printing frm spreading widely?
A. The printing prcess is cmplicated.
B. 3D fd printers are t expensive.
C. Fd materials have t be dry.
D. Sme experts dubt 3D fd printing.
50. What culd be the best title f the passage?
A. 3D Fd Printing: Delicius New Technlgy
B. A New Way t Imprve 3D Fd Printing
C. The Challenges fr 3D Fd Prductin
D. 3D Fd Printing: Frm Farm t Table
【文章大意】本文是一篇说明文。文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。

In the 1760s, Mathurin Rze pened a series f shps that basted(享有) a special meat sup called cnsmmé. Althugh the main attractin was the sup, Rze's chain shps als set a new standard fr dining ut, which helped t establish Rze as the inventr f the mdern restaurant.
Tday, schlars have generated large amunts f instructive research abut restaurants. Take visual hints that influence what we eat: diners served themselves abut 20 percent mre pasta(意大利面食) when their plates matched their fd. When a dark-clred cake was served n a black plate rather than a white ne, custmers recgnized it as sweeter and mre tasty.
Lighting matters, t. When Berlin restaurant custmers ate in darkness, they culdn't tell hw much they'd had: thse given extra-large shares ate mre than everyne else, nne the wiser—they didn’t feel fuller, and they were just as ready fr dessert.
Time is mney, but that principle means different things fr different types f restaurants. Unlike fast-fd places, fine dining shps prefer custmers t stay lnger and spend. One way t encurage custmers t stay and rder that extra rund: put n sme Mzart(莫扎特).When classical, rather than pp, music was playing, diners spent mre. Fast music hurried diners ut.

Children as yung as ten are becming dependent n scial media fr their sense f self-wrth, a majr study warned.
It fund many yungsters(少年）nw measure their status by hw much public apprval they get nline, ften thrugh “likes”. Sme change their behaviur in real life t imprve their image n the web.
The reprt int yungsters aged frm 8 t 12 was carried ut by Children's Cmmissiner (专员）Anne Lngfield. She said scial media firms were expsing children t majr emtinal risks, with sme yungsters starting secndary schl ill-equipped t cpe with the tremendus pressure they faced nline.
Sme scial apps were ppular amng the children even thugh they suppsedly require users t be at least 13.The yungsters admitted planning trips arund ptential pht-pprtunities and then messaging friends—and friends f friends — t demand “likes” fr their nline psts.
The reprt fund that yungsters felt their friendships culd be at risk if they did nt respnd t scial media psts quickly, and arund the clck.
Children aged 8 t 10 were "starting t feel happy" when thers liked their psts. Hwever, thse in the 10 t 12 age grup were "cncerned with hw many peple like their psts", suggesting a “need” fr scial recgnitin that gets strnger the lder they becme.
Miss Lngfield warned that a generatin f children risked grwing up "wrried abut their appearance and image as a result f the unrealistic lifestyles they fllw n platfrms, and increasingly anxius abut switching ff due t the cnstant demands f scial media.
She said: "Children are using scial media with family and friends and t play games when they are in primary schl. But what starts as fun usage f apps turns int tremendus pressure in real scial media interactin at secndary schl."
As their wrld expanded, she said, children cmpared themselves t thers nline in a way that was "hugely damaging in terms f their self-identity, in terms f their cnfidence, but als in terms f their ability t develp themselves".
Miss Lngfield added: "Then there is this push t cnnect—if yu g ffline, will yu miss smething, will yu miss ut, will yu shw that yu dn't care abut thse peple yu are fllwing, all f thse cme tgether in a huge way at nce." "Fr children it is very, very difficult t cpe with emtinally." The Children's Cmmissiner fr England's study—life in Likes—fund that children as yung as 8 were using scial media platfrms largely fr play.
Hwever, the research—invlving eight grups f 32 children aged 8 t 12—suggested that as they headed tward their teens, they became increasingly anxius nline.
By the time they started secndary schl—at age 11—children were already far mre aware f their image nline and felt under huge pressure t ensure their psts were ppular, the reprt fund.
Hwever, they still did nt knw hw t cpe with mean-spirited jkes, r the sense f incmpetence they might feel if they cmpared themselves t celebrities(名人）r mre brilliant friends nline. The reprt said they als faced pressure t respnd t messages at all hurs f the day—especially at secndary schl when mre yungsters have mbile phnes.
The Children’s Cmmissiner said schls and parents must nw d mre t prepare children fr the emtinal minefield(雷区）they faced nline. And she said scial media cmpanies must als "take mre respnsibility". They shuld either mnitr their websites better s that children d nt sign up t early, r they shuld adjust their websites t the needs f yunger users.
Javed Khan, f children's charity Bamard's, said: "It's vital that new cmpulsry age- apprpriate relatinship and sex educatin lessns in England shuld help equip children t deal with the grwing demands f scial media.
“It’s als hugely imprtant fr parents t knw which apps their children are using.”

A build-it-yurself slar still（蒸馏器） is ne f the best ways t btain drinking water in areas where the liquid is nt readily available. Develped by tw dctrs in the U.S. Department f Agriculture, it’s an excellent water cllectr. Unfrtunately, yu must carry the necessary equipment with yu, since it’s all but impssible t find natural substitutes. The nly cmpnents required, thugh, are a 5＇5＇ sheet f clear r slightly milky plastic, six feet f plastic tube, and a cntainer — perhaps just a drinking cup — t catch the water. These pieces can be flded int a neat little pack and fastened n yur belt.
T cnstruct a wrking still, use a sharp stick r rck t dig a hle fur feet acrss and three feet deep. Try t make the hle in a damp area t increase the water catcher’s prductivity. Place yur cup in the deepest part f the hle. Then lay the tube in place s that ne end rests all the way in the cup and the rest f the line runs up — and ut — the side f the hle.
Next, cver the hle with the plastic sheet, securing the edges f the plastic with dirt and weighting the sheet’s center dwn with a rck. The plastic shuld nw frm a cne(圆锥体) with 45-degree-angled sides. The lw pint f the sheet must be centered directly ver, and n mre than three inches abve, the cup.
The slar still wrks by creating a greenhuse under the plastic. Grund water evaprates(蒸发) and cllects n the sheet until small drps f water frm, run dwn the material and fall ff int the cup. When the cntainer is full, yu can suck the refreshment ut thrugh the tube, and wn’t have t break dwn the still every time yu need a drink.
32. What d we knw abut the slar still equipment frm the first paragraph?
A. It’s delicate. B. It’s expensive.
C. It’s cmplex. D. It’s prtable.
33. What des the underlined phrase ＂the water catcher＂ in paragraph 2 refer t?
A. The tube. B. The still.
C. The hle. D. The cup.
34. What is the last step f cnstructing a wrking slar still?
A. Dig a hle f a certain size. B. Put the cup in place.
C. Weight the sheet’s center dwn. D. Cver the hle with the plastic sheet.
35. When a slar still wrks, drps f water cme int the cup frm .
A. the plastic tube B. utside the hle
C. the pen air D. beneath the sheet
【文章大意】本文主要介绍了一种自己可以亲手制作的简单易行的太阳能蒸馏器的方法，并介绍了它的工作原理。这种蒸馏器所需的材料简单，适用于任何缺水的地方。
32. D 【解析】推理判断题。根据第一段最后一句话These pieces can be flded int a neat little pack and fastened n yur belt.可知制作蒸馏器的东西可以叠放在一个小包里，系在腰间，这说明制作蒸馏器的设备很轻便，prtable表示＂轻便的；手提的＂，故选D。
33. B 【解析】词义猜测题。根据Try t make the hle in a damp area t increase the water catcher’s prductivity可知最好在潮湿的地方挖洞，以提高接水器的工作效率。＂接水器＂指的是在潮湿的地方挖洞，在洞的底部放一个杯子，杯子上方用膜覆盖，整个装置构成接水器，而不是某个部分。这一题很容易错选D，但是就算在干燥的地方挖洞，杯子也可以接水，杯子接水的事实并不会因为周围环境的变化而变化，杯子的工作效率是不变的。故选B。
34. C 【解析】细节理解题。根据第三段Next, cver the hle with the plastic sheet, securing the edges f the plastic with dirt and weighting the sheet’s center dwn with a rck.可知最后一步是weighting the sheet’s center dwn with a rck(放一块石头在覆盖膜的中间，把它压下去)，故选C。
35. D 【解析】推理判断题。结合第四段中的Grund water evaprates(蒸发) and cllects n the sheet until small drps f water frm, run dwn the material and fall ff int the cup可知地下水蒸发，在覆盖膜上聚集起来，直到形成小水滴落在杯子里，覆盖膜是在杯子上面的，水滴落入杯子里，所以水滴是聚在覆盖膜的下面。故选D。

Terrafugia Inc. said Mnday that its new flying car has cmpleted its first flight, bringing the cmpany clser t its gal f selling the flying car within the next year. The vehicle — named the Transitin — has tw seats, fur wheels and wings that fld up s it can be driven like a car. The Transitin, which flew at 1,400 feet fr eight minutes last mnth, can reach arund 70 miles per hur n the rad and 115 in the air. It flies using a 23-galln tank f gas and burns 5 gallns per hur in the air. On the grund, it gets 35 miles per galln.
Arund 100 peple have already put dwn a $10,000 depsit t get a Transitin when they g n sale, and thse numbers will likely rise after Terrafugia intrduces the Transitin t the public later this week at the New Yrk Aut Shw. But dn’t expect it t shw up in t many driveways. It’s expected t cst $279,000. And it wn’t help if yu’re stuck in traffic. The car needs a runway.
Inventrs have been trying t make flying cars since the 1930s, accrding t Rbert Mann, an airline industry expert. But Mann thinks Terrafugia has cme clser than anyne t making the flying car a reality. The gvernment has already permitted the cmpany t use special materials t make it easier fr the vehicle t fly. The Transitin is nw ging thrugh crash tests t make sure it meets federal safety standards.
Mann said Terrafugia was helped by the Federal Aviatin Administratin’s decisin five years ag t create a separate set f standards fr light sprt aircraft, which are lwer than thse fr pilts f larger planes. Terrafugia says an wner wuld need t pass a test and cmplete 20 hurs f flying time t be able t fly the Transitin, a requirement pilts wuld find relatively easy t meet.
28. What is the first paragraph mainly abut?
A. The basic data f the Transitin.
B. The advantages f flying cars.
C. The ptential market fr flying cars.
D. The designers f the Transitin.
29. Why is the Transitin unlikely t shw up in t many driveways?

When a leafy plant is under attack, it desn’t sit quietly. Back in 1983, tw scientists, Jack Schultz and Ian Baldwin, reprted that yung maple trees getting bitten by insects send ut a particular smell that neighbring plants can get. These chemicals cme frm the injured parts f the plant and seem t be an alarm. What the plants pump thrugh the air is a mixture f chemicals knwn as vlatile rganic cmpunds, VOCs fr shrt.
Scientists have fund that all kinds f plants give ut VOCs when being attacked. It’s a plant’s way f crying ut. But is anyne listening? Apparently. Because we can watch the neighbrs react.
Sme plants pump ut smelly chemicals t keep insects away. But thers d duble duty. They pump ut perfumes designed t attract different insects wh are natural enemies t the attackers. Once they arrive, the tables are turned. The attacker wh was lunching nw becmes lunch.
In study after study, it appears that these chemical cnversatins help the neighbrs. The damage is usually mre serius n the first plant, but the neighbrs, relatively speaking, stay safer because they heard the alarm and knew what t d.
Des this mean that plants talk t each ther? Scientists dn’t knw. Maybe the first plant just made a cry f pain r was sending a message t its wn branches, and s, in effect, was talking t itself.

After years f heated debate, gray wlves were reintrduced t Yellwstne Natinal Park. Furteen wlves were caught in Canada and transprted t the park. By last year, the Yellwstne wlf ppulatin had grwn t mre than 170 wlves.
Gray wlves nce were seen here and there in the Yellwstne area and much f the cntinental United States, but they were gradually displaced by human develpment. By the 1920s, wlves had practically disappeared frm the Yellwstne area. They went farther nrth int the deep frests f Canada, where there were fewer humans arund.
The disappearance f the wlves had many unexpected results. Deer and elk ppulatins — majr fd surces (来源) fr the wlf — grew rapidly. These animals cnsumed large amunts f vegetatin (植被), which reduced plant diversity in the park. In the absence f wlves, cyte ppulatins als grew quickly. The cytes killed a large percentage f the park’s red fxes, and cmpletely drve away the park’s beavers.
As early as 1966, bilgists asked the gvernment t cnsider reintrducing wlves t Yellwstne Park. They hped that wlves wuld be able t cntrl the elk and cyte prblems. Many farmers ppsed the plan because they feared that wlves wuld kill their farm animals r pets.
The gvernment spent nearly 30 years cming up with a plan t reintrduce the wlvers. The U.S. Fish and Wildlife Service carefully mnitrs and manages the wlf packs in Yellwstne. Tday, the debate cntinues ver hw well the gray wlf is fitting in at Yellwstne. Elk, deer, and cyte ppulatins are dwn, while beavers and red fxes have made a cmeback. The Yellwstne wlf prject has been a valuable experiment t help bilgists decide whether t reintrduce wlves t ther parts f the cuntry as well.

Measles(麻疹), which nce killed 450 children each year and disabled even mre, was nearly wiped ut in the United States 14 years ag by the universal use f the MMR vaccine(疫苗). But the disease is making a cmeback, caused by a grwing anti-vaccine mvement and misinfrmatin that is spreading quickly. Already this year, 115 measles cases have been reprted in the USA, cmpared with 189 fr all f last year.
The numbers might sund small, but they are the leading edge f a dangerus trend. When vaccinatin rates are very high, as they still are in the natin as a whle, everyne is prtected. This is called ＂herd immunity＂, which prtects the peple wh get hurt easily, including thse wh can’t be vaccinated fr medical reasns, babies t yung t get vaccinated and peple n whm the vaccine desn’t wrk.
But herd immunity wrks nly when nearly the whle herd jins in. When sme refuse vaccinatin and seek a free ride, immunity breaks dwn and everyne is in even bigger danger.
That’s exactly what is happening in small neighbrhds arund the cuntry frm Orange Cunty, Califrnia, where 22 measles cases were reprted this mnth, t Brklyn, N.Y., where a 17-year-ld caused an utbreak last year.
The resistance t vaccine has cntinued fr decades, and it is driven by a real but very small risk. Thse wh refuse t take that risk selfishly make thers suffer.
Making things wrse are state laws that make it t easy t pt ut(决定不参加) f what are suppsed t be required vaccines fr all children entering kindergarten. Seventeen states allw parents t get an exemptin（豁免）, smetimes just by signing a paper saying they persnally bject t a vaccine.
Nw, several states are mving t tighten laws by adding new regulatins fr pting ut. But n ne des enugh t limit exemptins.
Parents ught t be able t pt ut nly fr limited medical r religius reasns. But persnal pinins? Nt gd enugh. Everyne enjys the life-saving benefits vaccines prvide, but they’ll exist nly as lng as everyne shares in the risks.
63. The first tw paragraphs suggest that ____________.
A. a small number f measles cases can start a dangerus trend
B. the utbreak f measles attracts the public attentin
C. anti-vaccine mvement has its medical reasns
D. infrmatin abut measles spreads quickly
64. Herd immunity wrks well when ____________.
A. exemptins are allwed

Hllywd’s thery that machines with evil(邪恶) minds will drive armies f killer rbts is just silly. The real prblem relates t the pssibility that artificial intelligence(AI) may becme extremely gd at achieving smething ther than what we really want. In 1960 a well-knwn mathematician Nrbert Wiener, wh funded the field f cybernetics（控制论）, put it this way: ＂If we use, t achieve ur purpses, a mechanical agency with whse peratin we cannt effectively interfere(干预), we had better be quite sure that the purpse put int the machine is the purpse which we really desire.＂
A machine with a specific purpse has anther quality, ne that we usually assciate with living things: a wish t preserve its wn existence. Fr the machine, this quality is nt in-brn, nr is it smething intrduced by humans; it is a lgical cnsequence f the simple fact that the machine cannt achieve its riginal purpse if it is dead. S if we send ut a rbt with the single instructin f fetching cffee, it will have a strng desire t secure success by disabling its wn ff switch r even killing anyne wh might interfere with its task. If we are nt careful, then, we culd face a kind f glbal chess match against very determined, super intelligent machines whse bjectives cnflict with ur wn, with the real wrld as the chessbard.
The pssibility f entering int and lsing such a match shuld cncentrate the minds f cmputer scientists. Sme researchers argue that we can seal the machines inside a kind f firewall, using them t answer difficult questins but never allwing them t affect the real wrld. Unfrtunately, that plan seems unlikely t wrk: we have yet t invent a firewall that is secure against rdinary humans, let alne super intelligent machines.
Slving the safety prblem well enugh t mve frward in AI seems t be pssible but nt easy. There are prbably decades in which t plan fr the arrival f super intelligent machines. But the prblem shuld nt be dismissed ut f hand, as it has been by sme AI researchers. Sme argue that humans and machines can cexist as lng as they wrk in teams—yet that is nt pssible unless machines share the gals f humans. Others say we can just ＂switch them ff＂ as if super intelligent machines are t stupid t think f that pssibility. Still thers think that super intelligent AI will never happen. On September 11, 1933, famus physicist Ernest Rutherfrd stated, with cnfidence, ＂Anyne wh expects a surce f pwer in the transfrmatin f these atms is talking mnshine.＂ Hwever, n September 12, 1933, physicist Le Szilard invented the neutrn-induced(中子诱导) nuclear chain reactin.
67. Paragraph 1 mainly tells us that artificial intelligence may __________.
A. run ut f human cntrl
B. satisfy human’s real desires
C. cmmand armies f killer rbts
D. wrk faster than a mathematician
68. Machines with specific purpses are assciated with living things partly because they might be able t __________.
A. prevent themselves frm being destryed
B. achieve their riginal gals independently
C. d anything successfully with given rders
D. beat humans in internatinal chess matches
69. Accrding t sme researchers, we can use firewalls t __________.
A. help super intelligent machines wrk better
B. be secure against evil human beings
C. keep machines frm being harmed
D. avid rbts’ affecting the wrld
70. What des the authr think f the safety prblem f super intelligent machines?

B. It will get wrse with human interference.
C. It will be slved but with difficulty.
D. It will stay fr a decade.

Befre birth, babies can tell the difference between lud sunds and vices. They can even distinguish their mther’s vice frm that f a female stranger. But when it cmes t embrynic learning(胎教),birds culd rule the rst. As recently reprted in The Auk: Ornithlgical Advances, sme mther birds may teach their yung t sing even befre they hatch(孵化). New-brn chicks can then imitate their mm’s call within a few days f entering the wrld.
This educatinal methd was first bserved in 2012 by Snia Kleindrfer, a bilgist at Flinders University in Suth Australia, and her clleagues. Female Australian superb fairy wrens were fund t repeat ne sund ver and ver again while hatching their eggs. When the eggs were hatched, the baby birds made the similar chirp t their mthers — a sund that served as their regular "feed me!" call.
T find ut if the special quality was mre widespread in birds, the researchers sught the red-backed fairy wren, anther species f Australian sngbird. First they cllected sund data frm 67 nests in fur sites in Queensland befre and after hatching. Then they identified begging calls by analyzing the rder and number f ntes. A cmputer analysis blindly cmpared calls prduced by mthers and chicks, ranking them by similarity.
It turns ut that baby red-backed fairy wrens als emerge chirping like their mms. And the mre frequently mthers had called t their eggs, the mre similar were the babies’ begging calls. In additin, the team set up a separate experiment that suggested that the baby birds that mst clsely imitated their mm’s vice were rewarded with the mst fd.
This bservatin hints that effective embrynic learning culd signal neurlgical(神经系统的) strengths f children t parents. An evlutinary inference can then be drawn. "As a parent, d yu invest in quality children, r d yu invest in children that are in need?"Kleindrfer asks. "Our results suggest that they might be ging fr quality."
58. The underlined phrase in Paragraph 1 means " ".
A.be the wrstB.be the best
C.be just as badD.be just as gd
59. What are Kleindrfer’s findings based n?
A. Similarities between the calls f mms and chicks.
B. The bservatin f fairy wrens acrss Australia.
C. The data cllected frm Queensland’s lcals.
D. Cntrlled experiments n wrens and ther birds.
60. Embrynic learning helps mther birds t identify the baby birds which .
A. can receive quality signalsB. are in need f training
C. fit the envirnment betterD. make the ludest call
【文章大意】文章介绍了鸟类在胎教方面的超凡本领。实验发现鸟儿在孵化时不停地鸣叫是为了教会以后出生的雏鸟歌唱的本领，从而挑选出能够适应环境的雏鸟。
58. B【解析】根据第二段＂when the errs were hatched, the baby birds made the similar chirp t their mthers＂可知，鸟儿在孵化小鸟的时候，鸣叫对未出生的小鸟有很大影响，它们被孵化后也能发出类似的声音，说明鸟儿很擅长胎教。
59. A【解析】根据第三段＂the researchers sught the red-backed fairy wren, anther species f Australian sngbird.＂可知，研究人员并未在全澳洲范围展开调查，排除B项；未对其它鸟类进行记录研究，排除D项。根据倒数第三段中的＂A cmputer analysis blindly cmpared calls prduced by mthers and chicks, ranking them by similarity.＂可知，A项正确。
60. C【解析】根据倒数第二段中的＂the baby birds that mst clsely imitated their mm’s vice were rewarded with the mst fd＂和最后一段＂Our results suggest that they might be ging fr quality.＂可知，模仿母鸟模仿得最好的雏鸟得到最多的食物，研究结果表明，母亲会选择质量好的雏鸟。由此可知，胎教帮助母鸟辨别出那些适应环境较好的孩子。

Old Prblem, New Appraches
While clean energy is increasingly used in ur daily life, glbal warming will cntinue fr sme decades after CO2 emissins(排放) peak. S even if emissins were t begin t decrease tday, we wuld still face the challenge f adapting t climate change. Here I will stress sme smarter and mre creative examples f climate adaptatin.
When it cmes t adaptatin, it is imprtant t understand that climate change is a prcess. We are therefre nt talking abut adapting t a new standard, but t a cnstantly shifting set f cnditins. This is why, in part at least, the US Natinal Climate Assessment says that: "There is n ‘ne-size fits all’ adaptatin." Nevertheless, there are sme actins that ffer much and carry little risk r cst.
Arund the wrld, peple are adapting in surprising ways, especially in sme pr cuntries. Flds have becme mre damaging in Bangladesh in recent decades. Mhammed Rezwan saw pprtunity where thers saw nly disaster. His nt-fr-prfit rganizatin runs 100 river bats that serve as flating libraries, schls, and health clinics, and are equipped with slar panels and ther cmmunicating facilities. Rezwan is creating flating cnnectivity(连接) t replace flded rads and highways. But he is als wrking at a far mre fundamental level: his staff shw peple hw t make flating gardens and fish pnds t prevent starvatin during the wet seasn.
Elsewhere in Asia even mre astnishing actins are being taken. Chewang Nrphel lives in a muntainus regin in India, where he is knwn as the Ice Man. The lss f glaciers(冰川) there due t glbal warming represents an enrmus threat t agriculture. Withut the glaciers, water will arrive in the rivers at times when it can damage crps. Nrphel’s inspiratin came frm seeing the waste f water ver winter, when it was nt needed. He directed the wasted water int shallw basins where it frze, and was stred until the spring. His fields f ice supply perfectly timed irrigatin(灌溉) water. Having created nine such ice reserves, Nrphel calculates that he has stred abut 200,000m3f water. Climate change is a cntinuing prcess, s Nrphel’s ice reserves will nt last frever. Warming will vertake them. But he is prviding a few years during which the farmers will, perhaps, be able t find ther means f adapting.
Increasing Earth’s reflectiveness can cl the planet. In suthern Spain the sudden increase f greenhuses(which reflect light back t space) has changed the warming trend lcally, and actually cled the regin. While Spain as a whle is heating up quickly, temperatures near the greenhuses have decreased. This example shuld act as an inspiratin fr all cities. By painting buildings white, cities may slw dwn the warming prcess.
In Peru, lcal farmers arund a muntain with a glacier that has already fallen victim t climate change have begun painting the entire muntain peak white in the hpe that the added reflectiveness will restre the life-giving ice. The utcme is still far frm clear. But the Wrld Bank has included the prject n its list f "100 ideas t save the planet".
Mre rdinary frms f adaptatin are happening everywhere. A friend f mine wns an area f land in western Victria. Over five generatins the land has been t wet fr crpping. But during the past decade declining rainfall has allwed him t plant highly prfitable crps. Farmers in many cuntries are als adapting like this — either by grwing new prduce, r by grwing the same things differently. This is cmmn sense. But sme suggestins fr adapting are nt. When the plluting industries argue that we’ve lst the battle t cntrl carbn pllutin and have n chice but t adapt, it’s a nnsense designed t make the case fr business as usual.
Human beings will cntinue t adapt t the changing climate in bth rdinary and astnishing ways. But the mst sensible frm f adaptatin is surely t adapt ur energy systems t emit less carbn pllutin. After all, if we adapt in that way, we may avid the need t change in s many thers.
65. The underlined part in Paragraph 2 implies .
A. adaptatin is an ever-changing prcess
B. the cst f adaptatin varies with time
C. glbal warming affects adaptatin frms
D. adaptatin t climate change is challenging
66. What is special with regard t Rezwan’s prject?
A. The prject receives gvernment supprt.
B. Different rganizatins wrk with each ther.
C. His rganizatin makes the best f a bad situatin.
D. The prject cnnects flded rads and highways.

【文章大意】文章关注的是我们熟悉的话题——气候变暖，不同的是，文章给出了一些应对气候变暖的新途径。
65.A 【解析】考查句意理解。根据上文中的"We are t a cnstantly shifting set f cnditins"可知，对于不断变化的环境，没有一个通用的方法来解决所有这样的问题。故画线部分暗示的是适应环境也是一个不断变化的过程。故A正确。
66.C 【解析】考查细节理解。根据第三段首句可知，世界范围内尤其是一些贫穷地区的人们使用了令人意想不到的方法去适应环境的改变，化劣势为优势，再结合下文的内容可知，Rezwan就是这么做的，故答案为C。
67.A 【解析】考查细节理解。由第四段中的" directed the wasted water int shallw basins where it frze， and was stred until the spring..."可知，他把水引入盆地，水在那里结冰并被存储到春天使用，故A正确。
68.D 【解析】考查细节理解。根据第六段的内容可知，在秘鲁当地的农民会把整个山峰涂成白色来增强对阳光的反射，希望借此来保护冰不被融化，再结合第五段的内容可知，反射太阳光可能会减轻全球变暖，故D项正确。
69.D 【解析】考查推理判断。根据第七段中的"When the plluting industries argue that we’ve lst the battle t cntrl carbn pllutin and have n chice but t adapt"可知，污染行业辩称因为人们没有赢得治理碳污染的战役，只能适应，再结合下文的"it’s a nnsense designed t make the case fr business as usual"可知，作者认为污染行业的这种说法是荒谬的，其目的是给自己的商业行为制造借口。由此可推知，对于污染行业来说，负责任的做法是同碳污染抗争，以减少碳排放，故D正确。
70.B 【解析】考查细节理解。根据最后一段第二句"But the mst sensible frm f adaptatin is surely t adapt ur energy systems t emit less carbn pllutin"可知，作者认为最明智的应对全球变暖的方法是减少碳排放，故B正确。

Getting less sleep has becme a bad habit fr mst American kids. Accrding t a new survey(调查)by the Natinal Sleep Fundatin, 51% f kids aged 10 t 18 g t bed at 10 pm r later n schl nights, even thugh they have t get up early. Last year the Fundatin reprted that nearly 60% f 7- t 12-year-lds said they felt tired during the day, and 15% said they had fallen asleep at schl.
Hw much sleep yu need depends a lt n yur age. Babies need a lt f rest; mst f them sleep abut 18 hurs a day! Adults need abut eight hurs. Fr mst schl-age children, ten hurs is ideal(理想的). But the new Natinal Sleep Fundatin survey fund that 35% f 10- t 12-year-lds get nly seven r eight hurs. And guess what almst half f the surveyed kids said they d befre bedtime? Watch TV.
"Mre children are ging t bed with TVs n, and there are mre pprtunities(机会)t stay awake, with mre hmewrk, the Internet and the phne," says Dr. Mary Carskadn, a sleep researcher at Brwn University Medical Schl. She says these activities at bedtime can get kids all excited and make it hard fr them t calm dwn and sleep. Other experts say part f the prblem is chemical. Changing levels f bdy chemicals called hrmnes nt nly make teenagers’ bdies develp adult characteristics, but als make it hard fr teenagers t fall asleep befre 11 pm.
Because sleepiness is such a prblem fr teenagers, sme schl districts have decided t start high schl classes later than they used t. Three years ag, schls in Edina, Minnesta, changed the start time frm 7:25 am t 8:30 am. Students, parents and teachers are pleased with the results.
25.What is the new Natinal Sleep Fundatin survey n?
A. American kids’ sleeping habits.B. Teenagers’ sleep-related diseases.
C. Activities t prevent sleeplessness.D. Learning prblems and lack f sleep.
26.Hw many hurs f sleep d 11-year-lds need every day?
A.7 hurs.B.8 hurs.C.10 hurs.D.18 hurs.
27.Why d teenagers g t sleep late accrding t Carskadn?
A. They are affected by certain bdy chemicals.
B. They tend t d things that excite them.
C. They fllw their parents’ examples.
D. They dn’t need t g t schl early.
