历年来高考试题中的生词量有增无减。《教学大纲》要求学生“读懂生词率不超过3%的传记、故事、记叙文、科普小品文和有关社会文史知识等不同题材的材料。”在英语阅读训练和测试中的生词障碍往往会成为学生理解的“绊脚石”，这些“绊脚石”的出现大致分五类：1．旧词新义，考查词汇表中未出现的词义；如：Nearby is the Indianaplis race curse, where the natin’s mst famus car race is held each year n May 30th.我们学过 curse的意思是“过程，课程”等，在此显然不符句意。根据上下文 curse是汽车赛举行的地方，可推断 curse在该句是“车道”或“跑道”的意思。2．合成词、转化词与派生词，如shplifting，heartbrken，cmputer-literate，decisin-thinking，imperfect等；3．“灵活”的常用词增多，这些词必须根据具体的上下文语境才能正确理解；4．“新鲜”的外国人名、地名、专有名称增多，这些词有些带有一定的文化背景5．超纲生词。
有的学生在阅读训练和测试中存在着“生词恐惧心理”，一遇到生词就有读不下去的感觉。那么阅读理解时遇到大量生词该怎么办? 查词典当然是排除词义障碍的一种方法，当然这只有在平常的阅读训练中才可以使用。但是，频繁的查阅词典既影响阅读速度，又容易破坏学生阅读的思路和兴趣。况且，一词多义是英语词汇的主要特点，词典不一定能为学生提供单词在特定的上下文中的具体或确切的含义。平时的练习中遇到生词不要马上查词典，可以通过一定的方法来猜测理解。猜测词义不仅是一项阅读技巧，也是高考阅读能力考查的一个方面，每年在高考阅读中都有猜测词义的试题。掌握正确方法快速而又准确地猜测出生词的含义，对提高阅读速度和答题效率相当重要。
该类题常见的考查形式有：
1. The phrase “…”in the sentence culd be replaced by ____.
2. The wrd “…” in the paragraph refers t ____.
3. What is the meaning f the underlined wrd in the paragraph? / What des the unlined wrd mean?
4. Which f the fllwing is the clsest in meaning t the phrase “…”?
5. The wrd “…” mst nearly means ____.
对此类试题，考生应该进行大胆猜测，但这种猜测不是胡乱的，盲目的，而是有一定的方法和技巧。下面介绍几种常见的猜测词义的方法供同学们加以运用。
1．构词法猜词
阅读中常常会遇到一些由熟悉的单词派生或合成的新词。掌握构词法对猜测词义很有帮助。如：unfreseeable.这个词，可以根据构词法把它拆成un, fre, see , able；其中 see 是词根，fre是“先，前，预”的含义，un是否定，able是“能……的，可……的”，因此unfreseeable是“未能预见到的”意思。
…Baker cncludes that peple d nt have the ability t sense when they’re being stared at. If peple dubt the utcme f his tw experiments, said Baker, “I suggest they repeat the experiments and see fr themselves.” …
70. The underlined wrd “utcme” in the last paragraph mst prbably means .
A. value B. result
C. perfrmance D. cnnectin
【答案】B
【解析】运用“构词法”进行猜测。动词词组cme ut 的意义为“露出、出现、显露出”。再根据句子的语境，可猜测出其意义是：(实验的)结果。
2．利用同义近义词猜词
在生词所出现的上下文中，有时会出现与之同义或近义的词语或结构，这时可从熟悉的词语中推知生词的含义。统称在词或短语之间有并列连词and或r，这些词语或短语在句中作相同的成分，并且and或r连接的两项内容在含义上是接近的或递进的，由此确定同等关系中的某个生词所属的义域，甚至推出它的大致词义。
…Fermat’s Last Therem（定理）, first put frward by the French mathematician Pierre de Fermat in the seventeenth century, the therem had baffled and beaten the finest mathematical minds, including a French wman scientists wh made a majr advance in wrking ut the prblem, and wh had t dress like a man in rder t be able t study at the Ecle Plytechnique. …
65. Which f the fllwing best explains the meaning f the wrd “baffle” as it is used in the text?
A. T encurage peple t raise questins.
B. T cause difficulty in understanding.
C. T prvide a persn with an explanatin.
D. T limit peple’s imaginatin.
【答案】B
【解析】由句中不难看出Fermat的定理使得最具有数学头脑的科学家绞尽脑汁（beat），并且在句中beaten和baffled处于同等的并列关系，根据这一信息可以推出baffle表示“使困惑、难倒、难以理解”的意思。
3．利用反义词猜词
对比是描述，说明事物的常用方式。在对比中，对比的事物是互为相反的，因此根据反义或对比关系可从已知推出未知。利用反义词来说明生词的意义，如反义词ht and cld, perfect and imperfect，甚至前、后句为肯定与否定或是与不是等，在句内词与词之间，在段内句与句之间的关系上起着互为线索的作用。
…A child’s birthday party desn’t have t be a hassle ; it can be a basket f fun, accrding t Beth Anacleri, an Evastn mther f tw, ages 4 and 18 mnths. …
74.What des the underlined wrd “hassle” prbably mean?
A. A party designed by specialists.
B. A plan requiring careful thught.
C. A situatin causing difficulty r truble.
D. A demand made by guests.
【答案】C
【解析】根据前句的否定desn’t与后句的肯定can be这一对比关系，可以判断出，为了庆祝孩子的生日，又不至于麻烦，可以买一个生日开心包。Hassle的意思应该与fun相反，而与difficulty, truble相近。答案为C。
4．利用上下文语境猜词
任何一篇文章中的句子在内容上都不是绝对孤立的，都跟句子所在的段落及整整篇文章有关。利用上下文提供的情景和线索，进行合乎逻辑的综合分析进而推测词义，是阅读过程中的一大关键，这也是近年来高考考查的热点。
【2019·天津卷，D】
Wuld yu BET n the future f this man？He is 53 years ld. Mst f his adult life has been a lsing struggle against debt and misfrtune. A war injury has made his left hand stp functining，and he has ften been in prisn. Driven by heaven-knws-what mtives，he determines t write a bk.
The bk turns ut t be ne that has appealed t the wrld fr mre than 350 years. That frmer prisner was Cervantes，and the bk was Dn Quixte（《堂吉诃德》）. And the stry pses an interesting questin: why d sme peple discver new vitality and creativity t the end f their days，while thers g t seed lng befre？
We've all knwn peple wh run ut f steam befre they reach life's halfway mark. I'm nt talking abut thse wh fail t get t the tp. We can't all get there.

C. Miss the pprtunity t succeed.
D. Lse the interest t cntinue learning.
【语篇解读】本文属于议论文，讲述要成功，就需要不断的学习，这样的生活才会有意义。
52.D
【解析】词义猜测题。根据第三段I’m talking abut peple wh have stpped learning n grwing because they have adpted the fixed attitudes and pinins that all t ften cme with passing years.故可知，作者谈论的不是那些没有到达巅峰的人，而是谈论那些不再学习成长的人，故可知run ut f steam可知，停止学习，故选D。
5．利用定义和解释猜词
有些文章，特别是科技文章，通常会对一些关键词给予定义，我们可以利用定义来猜测这些词的意思。释义法就是根据文章中的字里行间，对生词以定语（从句）、表语甚至用逗号、破折号等标点符号引出并加以解释说明的方式。
“Organic prduce is always better, ” Gld said. “The fd is free f pesticides (农药), and yu are generally supprting family farms instead f large farms. And mre ften than nt it is lcally (本地)grwn and seasnal, s it is mre tasty.” Gld is ne f a grwing number f shppers buying int the rganic trend, and supermarkets acrss Britain are cunting n mre like him as they grw their rganic fd business.
62. What is the meaning f “the rganic trend” as the wrds are used in the text?
A. Grwing interest in rganic fd.
B. Better quality f rganic fd.
C. Rising market fr rganic fd.
D. Higher prices f rganic fd.
【答案】A
【解析】由Gld is ne f a grwing number f shppers buying smething可以推断出，越来越多的顾客像Gld一样开始购买有机食物，其实也就是对这类食物产生了越来越浓厚的兴趣。答案为A。
6．根据语义转折猜词
有时文章的作者为了增强表达效果，会用一些含有表示意思转折的连词，副词或短语。如：thugh, althugh, still, but, yet, instead, instead f, hwever, while, n the cntrary, n the ther hand, unlike, rather than, fr ne thing, fr anther等，我们可以根据转折意思猜测词义。
…Hwever bvius these facts may appear at first glance, they are actually nt s bvius as they seem except when we take special pains t think abut the subject.
…
71. In Paragraph 3, “take special pains” prbably means “_____”.
A. try very hard B. take ur time
C. are very unhappy D. feel especially painful
【答案析】A
【解析】由Hwever从句当中的at first glance（乍一眼看上去），与下文中的take special pains进行对比，既然不是一眼就看出那么简单，那么自然要费力去想了。由此可以推断出A项为最佳选项。
7．利用经验和常识猜词
…“I was n the way t a persnal-injury accident in West Nashville. As I gt nt Highway 40, blue lights and sirens(警笛) ging, I fell in behind a gld Pntiac Firebird that suddenly seemed t take ff quickly dwn the highway. The driver smehw panicked at the sight f me. He was ging mre than a hundred miles an hur and began passing cars n the shulder.”
63. The meaning f “panicked” in Paragraph 2 is related t ___________ .
A. shame B. hate C. anger D. fear
【答案】D
【解析】根据本段内容描述，可以知道panicked 意思是“惊慌”，相当于fear。

Passage4(2019·北京卷，D)
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

Passage1(2018·新课标卷I，C)
Languages have been cming and ging fr thusands f years, but in recent times there has been less cming and a lt mre ging. When the wrld was still ppulated by hunter-gatherers, small, tightly knit (联系)grups develped their wn patterns f speech independent f each ther.Sme language experts believe that 10,000 years ag, when the wrld had just five t ten millin peple, they spke perhaps 12,000 languages between them.
Sn afterwards, many f thse peple started settling dwn t becme farmers, and their languages t became mre settled and fewer in number. In recent centuries, trade, industrializatin, the develpment f the natin-state and the spread f universal cmpulsry educatin, especially glbalisatin and better cmmunicatins in the past few decades, all have caused many languages t disappear, and dminant languages such as English, Spanish and Chinese are increasingly taking ver.
At present, the wrld has abut 6,800 languages. The distributin f these languages is hugely uneven. The general rule is that mild znes have relatively few languages, ften spken by many peple, while ht, wet znes have lts, ften spken by small numbers. Eurpe has nly arund 200 languages; the Americas abut 1,000; Africa 2 400; and Asia and the Pacific perhaps 3,200, f which Papua New Guinea alne accunts fr well ver 800. The median number (中位数)f speakers is a mere 6,000, which means that half the wrld’s languages are spken by fewer peple than that.
Already well ver 400 f the ttal f, 6,800 languages are clse t extinctin(消亡), with nly a few elderly speakers left. Pick, at randm, Busuu in Camern (eight remaining speakers),Chiapanec in Mexic(150), Lipan Apache in the United States(tw r three)r Wadjigu in Australia (ne, with a questin-mark): nne f these seems t have much chance f survival.
28. What can we infer abut languages in hunter-gatherer times?
A. They develped very fast. B. They were large in number.
C. They had similar patterns. D. They were clsely cnnected.
29. Which f the fllwing best explains "dminant " underlined in paragraph 2？
A. Cmplex. B. Advanced.
C. Pwerful. D. Mdern.
30. Hw many languages are spken by less than 6, 000 peple at present?
A. Abut 6,800 B. Abut 3,400
C. Abut 2,400 D. Abut 1,200
31. What is the main idea f the text?
A. New languages will be created.
B. Peple’s lifestyles are reflected in languages.
C. Human develpment results in fewer languages.
D. Gegraphy determines language evlutin.

Passage4(2018·北京卷，D)
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.

Passage1(2017·新课标卷II，D)
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 neighburs 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. Perhaps the neighbrs just happened t “verhear” the cry. S infrmatin was exchanged, but it wasn’t a true, intentinal back and frth.
Charles Darwin, ver 150 years ag, imagined a wrld far busier, nisier and mre intimate(亲密的)

34.Scientists find frm their studies that plants can .
A. predict natural disasters
B. prtect themselves against insects
C. talk t ne anther intentinally

Passage2(2017·新课标III卷，C)
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.
28. What is the text mainly abut?
A. Wildlife research in the United States.
B. Plant diversity in the Yellwstne area.
C. The cnflict between farmers and gray wlves.
D. The reintrductin f wlves t Yellwstne Park.
29. What des the underlined wrd ＂displaced＂ in paragraph 2 mean?
A. Tested.B. Separated.
C. Frced ut.D. Tracked dwn.
30. What did the disappearance f gray wlves bring abut?
A. Damage t lcal eclgy.
B. A decline in the park’s incme.
C. Preservatin f vegetatin.
D. An increase in the variety f animals.
31. What is the authr’s attitude twards the Yellwstne wlf prject?

Passage3(2017·天津卷)
This mnth, Germany’s transprt minister, Alexander Dbrindt, prpsed the first set f rules fr autnmus vehicles(自主驾驶车辆). They wuld define the driver’s rle in such cars and gvern hw such cars perfrm in crashes where lives might be lst.
The prpsal attempts t deal with what sme call the “death valley” f autnmus vehicles: the grey area between semi-autnmus and fully driverless cars that culd delay the driverless future.
Dbrindt wants three things: that a car always chses prperty(财产) damage ver persnal injury; that it never distinguishes between humans based n age r race; and that if a human remves his r her hands frm the driving wheel — t check email, say — the car’s maker is respnsible if there is a crash.
“The change t the rad traffic law will permit fully autmatic driving,” says Dbrindt. It will put fully driverless cars n an equal legal fting t human drivers, he says.
Wh is respnsible fr the peratin f such vehicles is nt clear amng car makers, cnsumers and lawyers. “The liability(法律责任) issue is the biggest ne f them all,” says Natasha Merat at the University f Leeds, UK.
An assumptin behind UK insurance fr driverless cars, intrduced earlier this year, insists that a human “be watchful and mnitring the rad” at every mment.
But that is nt what many peple have in mind when thinking f driverless cars. “When yu say ‘driverless cars’, peple expect driverless cars.” Merat says. “Yu knw — n driver.”
Because f the cnfusin, Merat thinks sme car makers will wait until vehicles can be fully autmated withut peratin.
Driverless cars may end up being a frm f public transprt rather than vehicles yu wn, says Ryan Cal at Stanfrd University, Califrnia. That is happening in the UK and Singapre, where gvernment-prvided driverless vehicles are being launched.
That wuld g dwn prly in the US, hwever. “The idea that the gvernment wuld take ver driverless cars and treat them as a public gd wuld get abslutely nwhere here,” says Cal.
46. What des the phrase “death valley” in Paragraph 2 refer t?
A. A place where cars ften break dwn.
B. A case where passing a law is impssible.
C. An area where n driving is permitted.
D. A situatin where drivers’ rle is nt clear.
47. The prpsal put frward by Dbrindt aims t __________.
A. stp peple frm breaking traffic rules
B. help prmte fully autmatic driving
C. prtect drivers f all ages and races
D. prevent serius prperty damage
48. What d cnsumers think f the peratin f driverless cars?
A. It shuld get the attentin f insurance cmpanies.
B. It shuld be the main cncern f law makers.
C. It shuld nt cause deadly traffic accidents.
D. It shuld invlve n human respnsibility.
49. Driverless vehicles in public transprt see n bright future in _________.
A. SingapreB. the UK
C. the USD. Germany
50. What culd be the best title fr the passage?
A. Autnmus Driving: Whse Liability?
B. Fully Autmatic Cars: A New Breakthrugh

D. Driverless Cars: Rt f Rad Accidents
Passage4(2017·江苏卷)
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 wrst B. be the best
C. be the as bad D. 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 signals
B. are in need f training
C. fit the envirnment better

Passage 1(天津市红桥区2019届高三下学期第一次模拟考试)
Yur next Saturday night takeaway culd be brught t yu by a rbt after a majr fd delivery cmpany annunced plans t use autmated vehicles t transprt meals. Eurpe’s biggest nline takeaway fd cmpany Just Eat has partnered with Starship Technlgies t deliver fd with rbts n the streets f Lndn later this mnth. “Nbdy has ever dne deliveries with land-based rbts,” said Allan Martinsn, the chief perating fficer f Starship.
The rbt curier can travel up t 4 miles per hur fr abut 10 miles. It uses a GPS signal and nine cameras t navigate (确定方向). Instead f a persn arriving at their dr, custmers culd find themselves receiving a ntificatin n their phne that says a rbt is n its way and a cde t unlck the autmated curier. “Put the cde in, the rbt pens up, and there’s yur fd,” said David Buttress, chief manager f Just Eat.
The rbt, which has s far been tested in Greenwich, Miltn Keynes and Glastnbury, csts £ 1 t transprt within 3 miles, cmpared with the £3 t £6 it csts fr a human curier. T date 30 rbts have driven nearly 5,000 miles withut getting int an accident r finding themselves picked n by passers-by. They have driven in mre than 40 cities arund the wrld, including Lndn and Tallinn, Estnia.
An initial wrry was hw the public wuld react t rbts. But Martinsn said the public has been calm when passing the delivery machine n the streets. “The mst surprising reactin has been the lack f reactin,” said Martinsn.
Anther significant fear was that peple wuld disrupt (扰乱) the rbts, r try t steal them and their cntents. T prevent this, the rbt is fitted with nine cameras, tw way audi, and mvement sensrs that send a warning if it is lifted ff the grund. And it pens nly with a passcde prvided t the custmer via a ntificatin. “It’s much easier t shplift than it is t steal a rbt,” said Martinsn.

Passage 2(湖南省长沙市雅礼中学2019届高三一模)
Laughter is part f the universal human vcabulary. All members f the human species understand it. Unlike English r French r Swahili, we dn’t have t learn t speak it. We re brn with the capacity t laugh.
Very little is knwn abut the specific brain mechanisms respnsible fr laughter. Cntrary t flk wisdm, mst laughter is nt abut humr; it is abut relatinships. T find ut when and why peple laugh, I went with several assistants t lcal malls and recrded what happened just befre peple laughed. Over a 10-year perid, we studied ver 2,000 cases f naturally ccurring laughter.
We fund that mst laughter des nt necessarily fllw jkes. Peple may laugh after a variety f statements, such as, “Here cmes Mary,” “Hw did yu d n the test?” r “D yu have a rubber band?” These certainly aren’t jkes.
We believe laughter evlved frm the panting (喘气的) behavir f ur ancient ancestrs. Tday, if we tickle (使发痒) chimps, they dn’t laugh. But, instead, they prduce a panting sund. That’s the sund f ape laughter, and it’s the rt f human laughter.
Apes laugh in the kinds f situatins that lead t human laughter, like games that invlve chasing. Other animals prduce sunds during play, but they are s different frm laughter. Rats, fr example, prduce high sunds during play and when tickled, but these are very different in sund frm human laughter.
Laughter is ften psitive, but it can be negative t. There’s a difference between “laughing with” and “laughing at”. Peple wh laugh at thers may be trying t drive them ut f the grup.
N ne has actually cunted hw much peple f different ages laugh, but yung children prbably laugh the mst. At ages 5 and 6 we prbably laugh mre than at any ther times. Adults laugh less than children, prbably because they play less.
Wrk nw underway will tell us mre abut the brain mechanisms behind laughter, hw it has evlved, and why we’re s susceptible t tickling.
1. What was the purpse f the decade’s research?
A. T prve that peple laugh because f humur.
B. T find ut the real reasn fr peple s laughter.
C. T research peple s different reactin n jkes.
D. T recrd cnversatins amng shppers in malls.
2. What can we learn frm the text?
A. Peple wh play mre tend t laugh mre.
B. Apes prduce high sunds when tickled.
C. Scientists knw the brain mechanisms respnsible fr laughter well.
D. The situatins in which apes laugh are very different frm thse in which humans laugh.
3. What des the underlined wrd “susceptible” in the last paragraph prbably mean?

【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。

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。
