B
Like mst f us, I try t be mindful f fd that ges t waste. The arugula (芝麻菜)was t make a nice green salad, runding ut a rast chicken dinner. But I ended up wrking late. Then friends called with a dinner invitatin. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even wrse, I had unthinkingly bught way t much; I culd have made six salads with what I threw ut.
In a wrld where nearly 800 millin peple a year g hungry, “fd waste ges against the mral grain,” as Elizabeth Ryte writes in this mnth’s cver stry. It’s jaw-drpping hw much perfectly gd fd is thrwn away — frm “ugly” (but quite eatable) vegetables rejected by grcers t large amunts f uneaten dishes thrwn int restaurant garbage cans.
Prducing fd that n ne eats wastes the water, fuel, and ther resurces used t grw it. That makes fd waste an envirnmental prblem. In fact, Ryte writes, “if fd waste were a cuntry, it wuld be the third largest prducer f greenhuse gases in the wrld.”
If that’s hard t understand, let’s keep it as simple as the arugula at the back f my refrigeratr. Mike Curtin sees my arugula stry all the time — but fr him, it's mre like 12 bnes f dnated strawberries nearing their last days. Curtin is CEO f DC Central Kitchen in Washingtn, D.C., which recvers fd and turns it int healthy meals. Last year it recvered mre than 807,500 punds f fd by taking dnatins and cllecting blemished (有瑕疵的) prduce that therwise wuld have rtted in fields. And the strawberries? Vlunteers will wash, cut, and freeze r dry them fr use in meals dwn the rad.
Such methds seem bvius, yet s ften we just dn’t think. “Everyne can play a part in reducing waste, whether by nt purchasing mre fd than necessary in yur weekly shpping r by asking restaurants t nt include the side dish yu wn’t eat,” Curtin says.
24. What des the authr want t shw by telling the arugula stry?
A. We pay little attentin t fd waste.B. We waste fd unintentinally at times.
C. We waste mre vegetables than meat.D. We have gd reasns fr wasting fd.
25. What is a cnsequence f fd waste accrding t the test?
A. Mral decline.B. Envirnmental harm.
C. Energy shrtage.D. Wrldwide starvatin.
26. What des Curtin’s cmpany d?
A. It prduces kitchen equipment.B. It turns rtten arugula int clean fuel.
C. It helps lcal farmers grw fruits.D. It makes meals ut f unwanted fd.
27. What des Curtin suggest peple d?
A. Buy nly what is needed.B. Reduce fd cnsumptin.
C. G shpping nce a week.D. Eat in restaurants less ften.

Can a small grup f drnes (无人机) guarantee the safety and reliability f railways and, at the same time, help railway peratrs save billins f eurs each year? That is the very likely future f applying tday’s “eyes in the sky” technlgy t making sure that the millins f kilmetres f rail tracks and infrastructure (基础设施) wrldwide are safe fr trains n a 24/7 basis.
Drnes are already being used t examine high-tensin electrical lines. They culd d precisely the same thing t inspect railway lines and ther vital aspects f rail infrastructure such as the crrect psitin f railway tracks and switching pints. The mre regularly they can be inspected, the mre railway safety, reliability and n-time perfrmance will be imprved. Csts wuld be cut and peratins wuld be mre efficient (高效) acrss the bard.
That includes huge savings in maintenance csts and better prtectin f railway persnnel safety. It is calculated that Eurpean railways alne spend apprximately 20 billin eurs a year n maintenance, including sending maintenance staff, ften at night, t inspect and repair the rail infrastructure. That can be dangerus wrk that culd be avided with drnes assisting the crews’ effrts.
By using the latest technlgies, drnes culd als start prviding higher-value services fr railways, detecting faults in the rail r switches, befre they can cause any safety prblems. T perfrm these tasks, drnes fr rail dn’t need t be flying verhead. Engineers are nw wrking n a new cncept: the rail drnes f the future.

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 dge 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 Line 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.
28. The new study fcused n whether dgs can_________.
A. distinguish shapes B. make sense f human faces
C. feel happy r angry D. cmmunicate with each ther
29. What can we learn abut the study frm paragraph 2?
A. Researchers tested the dgs in randm rder.
B. Diverse methds were adpted during training.
C. Pictures used in the tw stages were different
D. The dgs were phtgraphed befre the lest.
30. What is the last paragraph mainly abut?
A. A suggestin fr future studies. B. A pssible reasn fr the study findings.
C. A majr limitatin f the study D. An explanatin f the research methd.
答案与解析：
28.B 主旨大意题。根据短文首段的第二句“Dgs may inxdeed be able t distinguish betweenhappy and angry human faces, accrding t a new study”可知，一项新的研究表明,狗可能真地可以辨别人的表情是高兴还是愤怒，紧接着后文又详细介绍了研究过程和结论，即狗能够识别人的表情，且倒数第二段的“With ur study, we think we can nw cnfidently cnclude that at leastsme dgs can distinguish human faciall expressins”一句明确给出了结论。故选B项。

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.

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.

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.

At the start f the 20th century, an American engineer named Jhn Elfreth Watkins made predictins abut life tday. His predictins abut slwing ppulatin grwth, mbile phnes and increasing height were clse t the mark. But he was wrng in ne predictin: that everybdy wuld walk 10 miles a day.
Tday, in Australia, mst children n average fall 2,000 steps shrt f the physical activity they need t avid being verweight. In the early 1970s, 40 per cent f children walked t schl, while in 2010, it was as lw as 15 per cent.
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. But smewhere ver the daily walk mre abut my sn’s day cmes ut. I hear him making sense f friendship and its limits. This is the unexpected and rare parental pprtunity t hear mre.
Many primary schls supprt walking schl-bus rutes (路线), with days f regular, parent-accmpanied walks. Ding just ne f these a few times a week is better than nthing.

答案与解析
B 推理判断题 根据第一段最后一句But he was wrng in ne predictin: that everybdy wuld walk 10 miles a day.和第二段可知，作者通过这个美国人的预言，引出如今青少年缺乏锻炼导致过度肥胖这个主题。
C 事实细节题 根据第三段Families are pressed fr time ... living in car-dependent neighbrhds with limited public transprt.可知，父母因生活压力忙于工作，缺乏时间，导致青少年锻炼不够。题干中的decrease和文中第三段的decline是同义转述，答案lack f time和文中第三段的are pressed fr time是同义转述。
D 事实细节题 根据倒数第二段But smewhere ver the daily walk mre abut my sn’s day cmes ut. I hear him making sense f friendship and its limits. This is the unexpected and rare parental pprtunity t hear mre.可知，作者在陪伴儿子散步时得知了他对友谊的理解等内心想法，让作者对儿子有了进一步的了解。

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, signalling: “Climb n me.” The yungster immediately jumps n t its mther’s 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 animals cnvey with nn-verbal cmmunicatin. S, it seems the gulf remains.”
27. 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.
28. What did Dr Shultz think f the study?
A. It was well designed but prly cnducted.
B. It was a gd try but the findings were limited.
C. It was inspiring but the evidence was unreliable.
D. It was a failure but the methds deserved praise.
29. What des the underlined wrd “gulf” in the last paragraph mean?

30. Which f the fllwing is the best title fr the text?
A. Chimpanzee behaviur study achieved a breakthrugh
B. Chimpanzees develped specific cmmunicatin skills
C. Chimpanzees: the smartest species in the animal kingdm
D. Chimpanzee language: cmmunicatin gestures translated
答案与解析
D 事实细节题 根据人名 Dr Hbaiter定位到文章第二段，再根据Only humans and chimps, she said, had a system f cmmunicatin where they deliberately sent a message t anther grup member.可知，Dr Hbaiter认为黑猩猩和人类的相似之处是有目的地传递信息。
B 事实细节题 根据人名Dr Shultz定位到文章第六段，再根据... 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”. 可知，Dr Shultz认为这项研究值得称赞，但研究成果有限。
29. A 词义猜测题 根据Mrever, the meanings seem t nt g beynd what ther animals cnvey with nn-verbal cmmunicatin. 可知，黑猩猩手势传递的信息的意义，并没有超出其他动物通过非语言方式传达的含义，因此和人类的语言交流方式还是存在差异。gulf在此意为“差异”。
30. D 主旨大意题 文章第一句即点明主旨，研究人员表明，他们已经破译出野生黑猩猩用来交流的手势的含义。

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 Ernest Hemingway’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 gifts, 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.

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.

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?

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.

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题详解】
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题详解】
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。

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 9：30 am, the full red/yellw/green signal cycle might be 140 secnds. By 9：33 am, a burst f additinal traffic might push it t 145 secnds. Less traffic at 9：37 am 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. It pays t put thery int practice.D. The simplest way is the best way.
【答案详解】
C 推理判断题
【解题思路】根据第二段第一句，即划线词所在句“That is by design”可知，that指代的事情是有意设计的，因此定位到第一段“Just like the traffic itself, the timing f the signals changes.”即信号灯变化的时间是可以灵活改变的，精心设计的。故选C。

Milwaukee, Wiscnsin, is rad testing a new way t keep winter rads ice-free — by spreading n them cheese brine, the salty liquid used t make sft cheeses, like mzzarella.
Wiscnsin, als called “America’s Dairyland,” is famus fr its cheese. The state prduced 2.8 billin punds f cheese last year! As a result, there was a lt f leftver cheese brine. Dispsing f (处置) the brine can be expensive. S what shuld cheese makers d with the waste?
Nrmally, twns use rck salt t de-ice streets. The salt lwers water’s freezing pint, causing ice t melt (融化). But using cheese brine culd help bth cheese prducers and cities save mney, while keeping rads safe. Cheese brine has salt in it, which, like the rck salt, helps lwer water’s freezing pint.
In additin t saving mney, cheese brine culd als be a mre ec-friendly ptin. Many peple suspect that all the rck salt used every winter is harming the envirnment.
Rck salt is made f sdium chlride, the same cmpund (化合物) in rdinary table salt. Sunds harmless, right? But while yu prbably add nly a small amunt f salt t yur fd, rad crews spread abut 20 millin tns f salt n U.S. rads every year!
The chemical washes ff rads and ges int the grund. There it can pllute drinking water, harm plants, and eat away sil. By spreading cheese brine n streets befre adding a layer f rck salt, Milwaukee may be able t cut its rck salt use by 30 percent.
Cheese brine has a dwnside t — a smell similar t that f bad milk. “I dn’t really mind it,” Emil Nrby tld Mdern Farmer magazine. He wrks fr ne f Wiscnsin’s cunty highway cmmissins and came up with the idea f using cheese brine. “Our rads smell like Wiscnsin!” he said.
24. Why can cheese brine help keep winter rads ice-free?

Have a hard time waking up when it’s cld ut? Scientists say yur brain is t blame. A study cnducted by scientists frm Nrthwestern University made it pssible t ffer sme explanatins fr this phenmenn.
Their study n fruit flies shws hw seasnally cld and dark cnditins can prhibit neurns within the fly brain that prmte activity and wakefulness frm sending ut signals, particularly in the mrning. It helps explains why, fr bth flies and humans, it is s hard t wake up in the mrning in winter.
“By studying behavirs in a fruit fly, we can better understand hw and why temperature is s vital t regulate sleep,” said Marc Galli, assciate prfessr f neurbilgy in the Weinberg Cllege f Arts and Sciences.
The study describes fr the first time “abslute cld” receptrs in the fly antenna, which respnd t temperature nly belw the fly’s “cmfrt zne” f abut 25°C．Having recgnized thse neurns, the researchers fllwed them all the way t their targets within the brain. They fund their targets are a small grup f brain neurns that are part f a larger netwrk that cntrls rhythms f activity and sleep. When the neurns they discvered are active, the target cells, which nrmally are made active by mrning light, are shut dwn.
“Temperature sensing is ne f the mst fundamental abilities,” said Galli, whse grup is ne f nly a few in the wrld that are systematically studying temperature sensing in fruit flies. “The principles we are finding in the fly brain, the lgic and rganizatin, may be the same all the way t humans. And future studies n human brain will surely find sme reference infrmatin in this study.”

While creating hard material frm mushrms might sund magical, the cmpany’s CEO Eben Bayer says it is a relatively lw-tech prcess and cmpares it t “making bread”. The cmpany begins by adding a few mycelium cells t damp hemp r ther agricultural waste.
The mycelium that grws like little hairs is allwed t twist with the waste until everything is ”glued“ tgether. The cmbinatin is then mixed again and placed int the desired mld (模具) where it cntinues t grw and harden. The resulting material is then baked in the ven. In additin t making it as strng as wd, the heat als kills the mycelium, thus giving the cmpstable material a similar shelf life t wd.
Als, thugh the table tps f the stylish Tafl and King’s tables released at the recently held Bifabricate 2016 cnference in New Yrk City resemble marble, they are far frm it. The perfectly carved blcks are made f a material grwn by a Nrth Carlina-based cmpany named biMASON using grains f sands and bacteria.
As yu have prbably guessed, this waste-free furniture des nt cme cheap. Custmers can expect t pay anywhere frm $249 USD fr the Tafl t $699 USD fr the King’s table, bth f which are nly available in limited quantities. Thse that cannt affrd thse prices can chse cheaper GIY (grw it yurself) nes made f varius prducts ranging frm Christmas tree decratins t lamp shades.
9．Why did Eben cmpare making hard materials t making bread?

Passage 6（2022·陕西·宝鸡中学模拟预测）
Fr thusands f years, mankind has bred plants and animals t create mre desired and useful plants and animals. Fr instance, mdern crn has been bred t such a large size that it is n lnger able t reprduce withut man’s assistance. Mdern dairy cws prduce t much milk; and if they are nt ften drained f milk, they culd leak, burst, becme infected, and pssibly die. Furthermre, mst dmesticated dgs can nt survive in the wild even with special training. Since natural evlutin is extremely slw and mankind’s selective breeding prgrams nly take a few generatins t prduce a cmpletely new species, natural evlutin has already taken a backseat t mankind’s breeding prgrams.
Additinally, mankind has successfully killed ff several species all tgether. Fr instance, there are n mre Eurpean wlves in existence and mammths prbably became extinct because f mankind. Even certain diseases have been permanently eradicated (根除) frm the planet, and dzens f ther diseases will sn fllw. Again, natural evlutin did nt cause mst extinctin during humanity’s reign.
Currently, scientists are creating new species with desired characteristics in the lab significantly faster than evlutin creates new species. In a single generatin, new species can be artificially created and destryed, while natural evlutin culd take thusands f years t d the same but nly haphazardly (偶然地). Scientists are even able t replace flawed (有缺陷的) r damaged genes with different genes in an attempt t cure genetic defects. This is smething that natural evlutin culd pssibly never crrect.
Eventually scientists will be able t enhance even peple. Fr example, imagine nt nly crrecting yur eyesight with gene therapy, but als ensuring that all f yur descendants d nt inherit yur ld genes f pr eyesight t. Scientists will ne day be able t enhance the memry and intelligence f yur children, s that they will d better in schl and achieve mre in life. Dctrs and scientists will be able t custmize babies befre they are brn just like picking ptins at a car dealership.
In the near future, natural evlutin in the genetic cde f any species can be quickly fixed if desired. As a result, natural evlutin is dmed.
21．Frm Paragraph 1 we learn that ______ .
A．selective breeding has imprved all species
B．nly selective breeding can make up fr natural lsses
C．mdern crn can’t able t reprduce itself due t selective breeding
D．natural evlutin can’t d withut man’s assistance
22．The underlined wrd “backseat ” in Paragraph 1 prbably means “ ______ ” .
A．pwerful assistanceB．imprtant part
C．bad frtuneD．secndary psitin
23．What d we knw frm the passage?
A．Selective breeding is partly beneficial t humans.
B．Genetic defects wn’t be inherited due t natural evlutin.
C．Natural evlutin can’t create new species.
D．Selective breeding can determine the sex f babies.
24．The authr mainly wants t tell us that ______ .

【导语】这是一篇说明文，文章讲述了人为进化的好处，如奶牛可以专门产奶，玉米的产量比以前也高很多，但是离开人类的照料那些动植物都不会很好的生存。在不久的将来，任何物种的遗传密码中的自然进化都可以在需要的情况下迅速得到修复。因此，自然进化是注定的。
21．【答案】C
【解析】细节理解题。根据第一段中“Fr instance, mdern crn has been bred t such a large size that it is n lnger able t reprduce withut man’s assistance.(例如，现代玉米已经被培育到如此大的尺寸，以至于没有人类的帮助它无法自己繁殖)”可知，由于选择性育种，现代玉米无法自己繁殖。故选C项。
22．【答案】D
【解析】词句猜测题。根据划线词前“Since natural evlutin is extremely slw and mankind’s selective breeding prgrams nly take a few generatins t prduce a cmpletely new species(由于自然进化极其缓慢，而人类的选择性繁殖程序只需要几代人就能产生一个全新的物种)”可知，人类的选择性繁殖速度比自然进化快得多，由此可推知，“natural evlutin has already taken a backseat t mankind’s breeding prgrams”意为：自然进化已经让位于人类的繁殖计划，backseat意为“次要位置”。故选D项。
23．【答案】A
【解析】推理判断题。根据第一段中“Fr thusands f years, mankind has bred plants and animals t create mre desired and useful plants and animals.(几千年来，人类一直在培育植物和动物，以创造出更理想、更有用的植物和动物)”及第二段中“Additinally, mankind has successfully killed ff several species all tgether.(此外，人类还成功地消灭了几个物种)”和“and dzens f ther diseases will sn fllw(其他几十种疾病也将接踵而至)”可知，选择性繁殖可以为人类带来财富，但也会导致物种灭绝，产生新的疾病，所以选择性繁殖只在一定程度上对人类有益。故选A项。
24．【答案】D
【解析】推理判断题。根据文章内容，结合最后一段“In the near future, natural evlutin in the genetic cde f any species can be quickly fixed if desired. As a result, natural evlutin is dmed.(在不久的将来，任何物种的遗传密码中的自然进化都可以在需要的情况下迅速得到修复。因此，自然进化是注定的)”可知，文章讲述了人为进化相比自然进化的好处及随之而来的问题，最后作者指出，自然进化可以在需要的情况下迅速得到修复，因而自然进化是注定的，所以文章想告诉我们，自然进化虽然处于危险之中，但仍会顽强地幸存下来，故选D项。
Passage 7（2022·安徽·合肥市第八中学模拟预测）
We are a culture drwning in ur pssessins. We take in mre and mre ( hliday, birthdays, sales, needs ),but rarely find an pprtunity t get rid f it. As a result, ur hmes fill up with s much stuff. And because we believe the best slutin is t find rganizatinal tls t manage all f it, we seek ut bigger cntainers r mre efficient rganizatinal tips and tricks. But simply rganizing ur stuff must be repeated ver and ver.
At its heart, rganizing is simply rearranging. And thugh we may find strage slutins tday, we are quickly frced t find new nes as early as tmrrw. Additinally, rganizing has sme ther majr shrtcmings that are rarely cnsidered. Fr example, it desn’t benefit anyne else. The pssessins we rarely use sit n shelves in ur basements r garages, even while sme f ur clsest friends desperately need them.
On the ther hand, the act f getting rid f stuff frm ur hme accmplishes many purpses. It is nt a temprary slutin. It is an actin f permanence — nce an item has been remved, it is remved cmpletely. Whether we re-sell ur pssessins, dnate them t charity, r give them t a friend, they are immediately put t use by thse wh need them.
Remving pssessins begins t turn back ur desire fr mre as we find freedm and happiness in wning less. And remving urselves frm the all-cnsuming desire t wn mre creates pprtunities fr significant life changes t take place.
If yu’re struggling with hw t get rid f stuff, yu can first challenge yurself t remve the unneeded things in yur hme, carry a trash bag frm rm-t-rm, see hw big f a dnatin pile yu can make, and even eliminate debt by selling what yu n lnger need.
It desn’t matter hw yu remve them, fr it is far better t remve than t always rganize.
25．What is the prblem with simply rganizing stuff?
A．Few tls and tricks are available.B．It needs t be repeated very ften.
C．Peple cannt save mney by rganizing.D．Desire t buy mre disappears by rganizing.
26．Hw can we remve unnecessary pssessins?
A．By reselling them t thers.B．By keeping them in trash bags.
C．By string them in the garage.D．By piling them n the shelves.
27．What des the underlined wrd “eliminate” mean in Paragraph 5?
A．get rid fB．get verC．add tD．take charge f
28．What is the purpse f the passage?
A．T explain the advantages and disadvantages f rganizing things.
B．T infrm readers f the ways t get rid f unnecessary pssessins.
C．T call fr peple t remve stuff instead f just rganizing.
D．T appeal t peple t make dnatins t peple in need.
【导语】本文为议论文，阐述了仅仅整理家里的物品并不能真的改善生活方式和自己的行为和理念，应当是彻底的舍弃，才能让物品既能物有所用，也能更好地整理自己的生活。
25．【答案】B
【解析】细节理解题。根据第一段的“But simply rganizing ur stuff must be repeated ver and ver.(但是，简单地组织我们的东西必须一遍又一遍地重复。)”可知，简单地整理东西的问题在于这需要经常重复。故选B。
26．【答案】A
【解析】细节理解题。根据第三段最后一句“Whether we resell ur pssessins, dnate them t charity, r give them t a friend, they are immediately put t use by thse wh need them.(无论我们转售我们的物品，捐赠给慈善机构，或给他们的朋友，他们立即被需要它们的人使用。)”可知，通过转卖物品，捐赠给慈善机构，赠送给朋友等方式，都可以让自己彻底摆脱不必要的物品，而且不浪费物品本身的价值。故选A。
27．【答案】A
【解析】词句猜测题。根据“selling what yu n lnger need(出售你不再需要的东西)”可知，卖掉不需要的东西后就可以得到钱，以此来摆脱债务，因此划线词的意思是“摆脱”，和get rid f意思相近，故选A。
28．【答案】C
【解析】推理判断题。通读全文，尤其是第一段的“And because we believe the best slutin is t find rganizatinal tls t manage all f it, we seek ut bigger cntainers r mre efficient rganizatinal tips and tricks. But simply rganizing ur stuff must be repeated ver and ver.(因为我们相信最好的解决方案是找到有组织的工具来管理所有这些，我们寻求更大的容器或更有效的组织技巧和技巧。但是，简单地组织我们的东西必须一遍又一遍地重复。)”和第二、三段的描述可知，本文主要分析仅仅整理物品的缺点和彻底清理物品的优点，以达到劝说人们“断舍离”的目的，因此本文的目的是号召人们清除杂物，而不仅仅是整理。故选C。
