A
The ddness f life in space never quite ges away. Here are sme examples.
First cnsider smething as simple as sleep. Its psitin presents its wn challenges. The main questin is whether yu want yur arms inside r utside the sleeping bag. If yu leave yur arms ut, they flat free in zer gravity, ften giving a sleeping astrnaut the lk f a funny ballet (芭蕾) dancer.
“I’m an inside guy, ” Mike Hpkins says, wh returned frm a six-mnth tur n the Internatinal Space Statin. “I like t be wrapped up. ”
On the statin, the rdinary becmes strange. The exercise bike fr the American astrnauts has n handlebars. It als has n seat. With n gravity, it’s just as easy t pedal vilently. Yu can watch a mvie while yu pedal by flating a micrcmputer anywhere yu want. But statin residents have t be careful abut staying in ne place t lng. Withut gravity t help circulate air, the carbn dixide yu exhale (呼气) has a tendency t frm an invisible (隐形的)clud arund yur head. Yu can end up with what astrnauts call a carbn-dixide headache.
Lery Chia, 54, an American retired astrnaut after fur flights, describes what happens even befre yu flat ut f yur seat. “Yur inner ear thinks yu’re falling. Meanwhile yur eyes are telling yu yu’re standing straight. That can be annying—that’s why sme peple feel sick. ” Within a cuple f days—truly terrible days fr sme—astrnauts’ brains learn t ignre the panicky signals frm the inner ear, and space sickness disappears.
Space travel can be s delightful but at the same time invisibly dangerus. Fr instance, astrnauts lse bne mass. That’s why exercise is cnsidered s vital that Natinal Aernautics and Space Administratin (NASA) puts it right n the wrkday schedule. The fcus n fitness is as much abut science and the future as it is abut keeping any individual astrnaut healthy. NASA is wrried abut tw things: recvery time nce astrnauts return hme, and, mre imprtantly, hw t maintain strength and fitness fr the tw and a half years r mre that it wuld take t make a rund-trip t Mars.
1. What is the majr challenge t astrnauts when they sleep in space?
A. Deciding n a prper sleep psitin.
B. Chsing a cmfrtable sleeping bag.
C. Seeking a way t fall asleep quickly.
D. Finding a right time t g t sleep.
2. The astrnauts will suffer frm a carbn-dixide headache when they_________.
A. circle arund n their bikes
B. use micrcmputers withut a stp
C. exercise in ne place fr a lng time
D. watch a mvie while pedaling
3. Sme astrnauts feel sick n the statin during the first few days because_________.
A. their senses stp wrking
B. they have t stand up straight
C. they flat ut f their seats unexpectedly
D. their brains receive cntradictry messages
4. One f NASA’s majr cncerns abut astrnauts is_________.
A. hw much exercise they d n the statin
B. hw they can remain healthy fr lng in space
C. whether they can recver after returning hme
D. whether they are able t g back t the statin

Preparing Cities fr Rbt Cars
The pssibility f self-driving rbt cars has ften seemed like a futurist’s dream, years away frm materializing in the real wrld. Well, the future is apparently nw. The Califrnia Department f Mtr Vehicles began giving permits in April fr cmpanies t test truly self-driving cars n public rads. The state als cleared the way fr cmpanies t sell r rent ut self-driving cars, and fr cmpanies t perate driverless taxi services. Califrnia, it shuld be nted, isn’t leading the way here. Cmpanies have been testing their vehicles in cities acrss the cuntry. It’s hard t predict when driverless cars will be everywhere n ur rads. But hwever lng it takes, the technlgy has the ptential t change ur transprtatin systems and ur cities, fr better r fr wrse, depending n hw the transfrmatin is regulated.
While much f the debate s far has been fcused n the safety f driverless cars (and rightfully s), plicymakers als shuld be talking abut hw self-driving vehicles can help reduce traffic jams, cut emissins (排放) and ffer mre cnvenient, affrdable mbility ptins. The arrival f driverless vehicles is a chance t make sure that thse vehicles are envirnmentally friendly and mre shared.
D we want t cpy—r even wrsen—the traffic f tday with driverless cars? Imagine a future where mst adults wn individual self-driving vehicles. They tlerate lng, slw jurneys t and frm wrk n packed highways because they can wrk, entertain themselves r sleep n the ride, which encurages urban spread. They take their driverless car t an appintment and set the empty vehicle t circle the building t avid paying fr parking. Instead f walking a few blcks t pick up a child r the dry cleaning, they send the self-driving minibus. The cnvenience even leads fewer peple t take public transprt—an unwelcme side effect researchers have already fund in ride-hailing (叫车) services.
A study frm the University f Califrnia at Davis suggested that replacing petrl-pwered private cars wrldwide with electric, self-driving and shared systems culd reduce carbn emissins frm transprtatin 80% and cut the cst f transprtatin infrastructure (基础设施) and peratins 40% by 2050. Fewer emissins and cheaper travel sund pretty appealing. The first cmmercially available driverless cars will almst certainly be fielded by ride-hailing services, cnsidering the cst f self-driving technlgy as well as liability and maintenance issues (责任与维护问题). But driverless car wnership culd increase as the prices drp and mre peple becme cmfrtable with the technlgy.
Plicymakers shuld start thinking nw abut hw t make sure the appearance f driverless vehicles desn’t extend the wrst aspects f the car-cntrlled transprtatin system we have tday. The cming technlgical advancement presents a chance fr cities and states t develp transprtatin systems designed t mve mre peple, and mre affrdably. The car f the future is cming. We just have t plan fr it.
5. Accrding t the authr, attentin shuld be paid t hw driverless cars can_______?
A. help deal with transprtatin-related prblems
B. prvide better services t custmers
C. cause damage t ur envirnment
D. make sme peple lse jbs
6. As fr driverless cars, what is the authr’s majr cncern?

A. Emplyed.
B. Replaced.
C. Shared.
D. Reduced.
8. What is the authr’s attitude t the future f self-drivingcars?
A. Dubtful.

I lve my mbile phne—it’s my little cnnectin t the larger wrld that can g anywhere with me. I als lve my cmputer, as it hlds all f my writing and thughts. Despite this lve f technlgy, I knw there are times when I need t mve away frm these things and truly cmmunicate with thers.
I teach a curse called Histry Matters in cllege. My gals fr the class include a deep discussin f histrical themes and ideas. Because I want students t fully study the material and exchange their ideas with each ther in the classrm, I have a rule—n laptps, iPads, phnes, etc. When students were tld my rule in advance f my class, sme f them were nt happy.
Mst students think my reasns fr this rule include unpleasant experiences in the past with students misusing technlgy. There’s a bit f truth t that. Sme students assume that I am anti-technlgy. There’s n truth in that at all. I lve technlgy and try t keep up with it s I can relate t my students.
The real reasn why I ask students t leave technlgy at the dr is that I think there are very few places in which we can have deep cnversatins and truly engage cmplex ideas. Interruptins (中断)by technlgy ften break cncentratin and allw fr t much dependence n utside infrmatin fr ideas. I want students t dig deep within themselves fr inspiratin and ideas. I want them t push each ther t think differently and t make cnnectins amng the curse, the material and the class discussin.
I’m nt saying that I wn’t ever change my mind abut technlgy use in my histry class, but until I hear a really gd reasn fr the change, I’m sticking t my plan. A few hurs f technlgy-free dialgue is just t sweet t give up.
9. Sme f the students in the histry class were unhappy with______.
A. the curse material
B. thers’ misuse f technlgy
C. discussin tpics
D. the authr’s class rule
10. Accrding t the authr, the use f technlgy in the classrm may _______.
A. keep students frm ding independent thinking
B. encurage students t have in-depth cnversatins
C. help students t better understand cmplex tpics
D. affect students’ cncentratin n curse evaluatin
11. It can be inferred frm the last paragraph that the authr ________.
A. is quite stubbrn
B. will give up teaching histry
C. will change his teaching plan sn
D. values technlgy-free dialgues in his class

（2019·全国Ⅰ卷）As data and identity theft becmes mre and mre cmmn, the market is grwing fr bimetric (生物测量) technlgies—like fingerprint scans—t keep thers ut f private e-spaces. At present, these technlgies are still expensive, thugh.
Researchers frm Gergia Tech say that they have cme up with a lw-cst device (装置)that gets arund this prblem: a smart keybard. This smart keybard precisely measures the cadence (节奏)with which ne types and the pressure fingers apply t each key. The keybard culd ffer a strng layer f security by analyzing things like the frce f a user’s typing and the time between key presses. These patterns are unique t each persn. Thus, the keybard can determine peple’s identities, and by extensin, whether they shuld be given access t the cmputer it’s cnnected t—regardless f whether smene gets the passwrd right.
It als desn’t require a new type f technlgy that peple aren’t already familiar with. Everybdy uses a keybard and everybdy types differently.
In a study describing the technlgy, the researchers had 100 vlunteers type the wrd “tuch” fur times using the smart keybard. Data cllected frm the device culd be used t recgnize different participants based n hw they typed, with very lw errr rates. The researchers say that the keybard shuld be pretty straightfrward t cmmercialize and is mstly made f inexpensive, plastic-like parts. The team hpes t make it t market in the near future.
12. Why d the researchers develp the smart keybard?
A. T reduce pressure n keys.
B. T imprve accuracy in typing.
C. T replace the passwrd system.
D. T cut the cst f e-space prtectin.
13. What makes the inventin f the smart keybard pssible?
A. Cmputers are much easier t perate.
B. Fingerprint scanning techniques develp fast.
C. Typing patterns vary frm persn t persn.
D. Data security measures are guaranteed.
14. What d the researchers expect f the smart keybard?
A. It’ll be envirnment-friendly.
B. It’ll reach cnsumers sn.
C. It’ll be made f plastics.
D. It’ll help speed up typing.
15. Where is this text mst likely frm?
A. A diary. B. A guidebk.

Once when Mike was a child, maybe eight years ld, he had a frightening experience. Mike thinks abut it frequently. He was in his huse with all his family. Mike cannt remember when it happened very well, but it was pssibly at Christmas. They were ging t have a big supper and Mike was very happy because he liked t eat a lt. Besides, Mike hadn’t eaten fr a lng time. Therefre, he was starving. He became very angry, because Mike saw his mther and his aunt talking fr a lng time.

答案：
[语篇解读]本文是一篇说明文。在太空中的生活有多神秘？这可能是你想象不到的。本文从不同角度介绍了在太空中生活时宇航员要面对的各种挑战。
1. A细节理解题。根据第二段第二句“Its psitin presents its wn challenges. ”可知，在太空中睡觉时，首先要面对的就是睡觉姿势的问题，这与A项中的 psitin吻合。其他三个选项表述片面，不能概括 psitin一词，所以选择A项。
2. C推理判断题。根据第三段中的“But statin residents have t be careful abut staying in ne place t lng. . . Yu can end up with what astrnauts call a carbn-dixide headache. ”可知，如果在一个地方待的时间太长，没有了重力帮助空气流通，呼出的二氧化碳就有可能在你的头附近形成隐形的云朵，你就会得氧化碳头疼症”，这与C项的表述吻合。A、B、D三项描述的都不是长时间在一个地方的活动，所以不会产生“二氧化碳头疼症”。
3. D推理判断题。根据第四段中的“Yur inner ear thinks yu’re falling. Meanwhile yur eyes are telling yu yu’re standing straight. That can be annying-that’s why sme peple feel sick”可知，在太空中，你的内耳认为你要倒下，而眼睛却告诉
你你在直立，也就是内耳和眼睛输出的信息是矛盾的，所以有些人会感到恶心，故选择D项。在太空中宇航员的感官不会停止工作，所以A项错误；B项是对文意的错误理解；C项表述的情况在太空中可能会发生，但是这种情况不会使宇航员感到恶心（feel sick），所以与题干不符，故排除。
4. B推理判断题。根据最后一段中的“NASA is wrried abut tw things. ，可知，NASA担心的是宇航员回家之后需要的恢复时间和怎样在两年半或更长时间的绕火星的旅行中保持体力和健康，这与B项中的 remain healthy fr lng in space相吻合，由此可知应该选择B项。A、D两项在原文中并没有提及，C项是对原文的错误理解。
[语篇解读]本文是一篇议论文。文章围绕无人驾驶汽车这项前沿科技，对以下方面进行了讨论：对无人驾驶汽车最大的担忧，对无人驾驶汽车未来发展的态度以及可能会出现的管理问题。
5. A细节理解题。根据第二段第一句“While much f the debate s far has been fcused n the safety…plicymakers als shuld be talking abut hw self-driving vehicles can help reduce traffic jams, cut emissins and ffer mre cnvenient，affrdable mbility ptins. ”可知，人们对无人驾驶汽车的关注点在其安全性以及有助于减少交通拥堵等方面。选项A“有助于解决与交通有关的问题”与此意思吻合。选项B“为消费者提供更好的服务”说法太笼统；选项C与第二段第一句中的cut emissins矛盾；选项D在文中没有提及。
6. D推理判断题。根据最后一段第一句“Plicymakers shuld start thinking nw abut hw t make sure the appearance f driverless vehicles desn’t extend the wrst aspects f the car-cntrlled transprtatin system we have tday. ”并结合上文内容可知，作者希望政策的制定者要考虑这些无人驾驶车辆的管理，不要扩大现有汽车管理运输系统中的最糟糕的方面，与选项D提到的“（车辆）管理”吻合，显然这是作者比较关心的。选项A是人们辩论的事情；选项B概括过于广泛；选项C是无人驾驶汽车的好处。
7. A词义猜测题。根据第四段中画线词所在句的前半部分内容the first cmmercially available driverless cars will almst certainly可知，结合下句中的 as the prices drp and mre peple becme cmfrtable with the technlgy可知，随着价格降低以及人们对这项技术开始应用自如，第一批上市的无人驾驶汽车会被用到“叫车服务”中。选项A“使用”符合题意。
8. B推理判断题。根据最后一段最后两句“The car f the future is cming. We just have t plan fr it”可知，无人驾驶汽车的时代就要来到，我们要准备好迎接它的到来。由此推断作者对于这种新科技持积极乐观的态度。选项A“怀疑的”，选项C“反对的”，选项D“同情的”，都不符合。
[语篇解读]本文是一篇议论文。手机能把作者和这个世界联系起来，电脑上保存着作者的文章和想法，作者对手机和电脑深爱不已，但是作为大学老师的他却反对学生在课堂上使用手机查阅资料。快来读一读文章，看看作者反对的原因吧。
9. D细节理解题。根据第二段中的“…I have a rule n laptps，iPads，phnes，etc. When students were tld my rule in advance f my class，sme f them were nt happy. "可知，作者规定学生在课堂上不能使用电脑、手机等，当学生被告知这个规定时部分学生不开心，即部分学生对班规有不满的情绪，故选D项。
10. A细节理解题。根据第四段中的“Interruptins by technlgy ften break cncentratin and allw fr t much dependence n utside infrmatin fr ideas. "可知，使用科技产品让学生不能专注，同时也让学生过于依赖从外部信息来获得想法，故选A项。B项是不使用科技产品可以达到的结果；文中说，不使用科技产品学生可以探索复杂的想法，但是有了科技产品，大家的专注就会被打断，故C项不符合题意；D项意为“影响学生对课程评价的专注”，文中未提及课程评价，故此项也不符合要求。
11. D推理判断题。通过最后一段中的“…I’m sticking t my plan A few hurs f technlgy-free dialgue is just t sweet t give up. ”可知，作者很享受大家一起远离科技产品的对话，不会放弃现在的班规，这个表述和D项吻合。此题容易错选A项，stubbrn固执的，暗含“即使别人提的建议正确，也不会听取”的意思，和最后一段第一句不符。
[语篇解读]本文是一篇科研报道。来自佐治亚理工学院的研究人员发明了一种智能键盘，可以通过分析用户的打字模式来判断该用户是不是安全访客。
12. D推理判断题。根据第二段第一句“Researchers frm Gergia Tech say that they have cme up with a lw-cst device that gets arund this prblem：a smart keybard. "以及第一段最后一句At present，these technlgies are still expensive，thugh”可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。注意题干、正确选项以及原文中一些词汇的多次呼应现象：develp与 cme up with是同义词，expensive与lw-cst是反义词，cut the cst与lw-cst相呼应。
13. C推理判断题。题干问的是“是什么让智能键盘的发明成为可能”，也就是问这一发明的核心依据是什么。根据第二段中“These patterns are unique t each persn. Thus, the keybard can determine peple’s identities. ”可知，正是因为每个人的打字模式不同，所以这种智能键盘可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客，故C项符合题意。解答该题的关键是看懂题干的意思，即智能键盘的核心依据是什么。
14. B细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“The team hpes t make it t market in the near future. ”，该团队希望在不久的将来将智能键盘推向市场，故选B项。题干中的 expect与原文中的hpe呼应，答案选项中的 cnsumers与原文中的 market呼应。
15. D文章出处题。根据本文的话题“智能键盘”以及第二段中的Researchers frm Gergia Tech say that they have cme up with allw-cst device…”尤其是其中的关键词 researchers，lw cst device等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。
[语篇解读]本文是一篇说明文，介绍了在选修网络课程时如何与授课老师建立健康有益的互动交流。这篇文章视角独特，倡导积极和谐的人际关系和人文情怀。
16. E关联逻辑法解题。空格前说，在网络课堂上，与授课老师建立健康的沟通模式是非常重要的，空格后说，虽然“我”每个只列出了两条，但显然还有许多其他情况可能发生。下面的段落紧接着介绍了沟通的注意事项——两“做”和两“不做”，因此E项“下面是在线学习者应该做和不应该做的一些常见事情符合语境。本设空类型属于细节理解类。
17. G设题位置法解题。空格后说，与主题内容相关的问题通常会受欢迎。在询问有关课程设计的问题之前，阅读教学大纲和学习管理系统信息，以确保答案不会隐藏在眼皮底下。由此可推知，此段表达要提出好的有水平的问题，故选G项“问问题，但要确保这些问题是好的、深思熟虑的问题”。本设空类型属于段落主题句类。
18. A关联逻辑法解题。空格前说，参加论坛、博客和其他开放式论坛来进行对话，空格后为参加论坛等的一些注意事项，A项“那就是它们的作用”符合语境。本设空类型属于细节理解类。
19. C关联逻辑法解题。空格前交代，如果你需要延长最后期限只需向授课老师解释一下情况，故选C项“如果需要更多的信息，他们会询问”。本设空类型属于细节理解类。
20. F关联逻辑法解题。空格前说，不要公开表达对授课老师或课程的不满，空格后提及，如果授课老师的专业水平或能力确实令人担忧，一定要使用在线课程评价来冷静地发表你的意见，因此F项“每个人都曾经有过不太好的上课经历”符合语境。本设空类型属于细节理解类。
[语篇解读]本文是一篇说明文。你能想象出没有电话的生活吗？电话给我们带来了怎样的影响呢？让我们一起读这篇文章来了解一下吧！
21. A break ut爆发；take ut拿出；set ut出发；put ut扑灭。此处指火灾的突然发生，故选A项。
22. D由下文的 yu culd nt call a dctr可知此处应选择与call a dctr相关的选项。在四个选项中与 call a dctr关系最密切的是sick（生病的）。unfair不公平的；angry生气的；unhappy不快乐的。
23. A不管是 family life（家庭生活）还是 schl life（学校生活）都属于我们的 daily life（日常生活），而 natural life表示“自然生活”。
24. B句意：我们大多是通过与别人谈话和倾听别人必须和我们说的话的方式进行交流的……nly意为“只”；mstly意为“大部分，大多数”；quickly意为“迅速地”；well意为“好”。
25. C由 we can d this very easily可知此处指“当我们离他们近的时候”。be clse t是固定搭配，意为“离…近”。
26. A hwever然而，表转折，而且常用逗号与句子的其他部分隔开。f curse当然；therefre因此；fr example例如。
27. B句意：然而，即使当我们大声喊叫（shut）的时候，我们的声音也不能传很远……在四个选项中，cry意为“哭喊”；shut意为“大声喊叫”；call表示一般的“喊叫”；laugh意为“笑”。故shut符合句意。
28. D experiment实验；Imprvement改善；discvery发现，指发现原来世界上有而不为人所知的东西；Inventin发明，指发明创造出一个新东西。故选D项。
29. D句意：正是由于电话的发明，当我们相隔很远时仍然能互相交流、谈话。因此选择still（仍然）。nt不；already已经；还。
30. a hear“听见”，强调结果；see“看见”，强调结果；listen t指“听的动作而不指“听”的结果；lk at指“看”的动作。此处指听”的结果，表示“我们能听清彼此的谈话”，故选A项。
31. B上文提到通过电话我们能够听清彼此的谈话，本句表示“使这成为可能的人是亚历山大·格拉汉姆·贝尔此处 pssible为最佳答案。clean干净的，necessary必要的，imprtant重要的，均与句意不符。
32. A spend time ding sth. 是固定结构。此处表示“贝尔把自己所有的空闲时间都用来做实验”。主句缺少谓语，故选A项。
33. B由本句后面的that. 可想到s…that或such…that结构，再由空后的形容词 enthusiastic可知应选择s。“s+adj. /adv. ”放在句首时，主句要用部分倒装。
34. A本文提到了贝尔发明电话，因此他做实验的目的是寻找一种通过电来传递人的言辞的方法。表示“传递”应用动词send。speech表示“说话，言辞”，可以与send搭配；作“演讲，演说”讲时，可以与give搭配，此时 speech是可数名词。
35. C句意：他是如此热衷于寻找用电传递人的言辞的方法，以至于他留下很少的时间用于日常工作……因此应用 little。
36. have/has seen 37. cnnected 38. which 39. us 40. the

第一节
One pssible versin：
Dear Chris，
I’m really wrried abut yur present situatin where yu’ve been addicted t webcast in summer hlidays and always spend a lt f time watching varius prgrams. My pinins are as fllws.
Undeniably，webcast is quite ppular amng yung peple，fr it makes leisure time clrful. Hwever，there exist sme ptential risks if we have excessive viewing f it. Initially, it may cause shrt-sightedness Besides，excessive viewing takes up t much time and energy which shuld be put int study.
Thus, never shuld we be an addict t webcast. It’s wiser t set aside sme time t accmpany parents r d smething mre meaningful.
Best wishes!
Yurs truly,
Li Hua
