The 8-year-old is the joke of the class. With shinning dark eyes, he seems like the kind of kid who would enjoy public speaking.But he’s nervous. “I’m here to tell you today why you should … should…” Chris trips on the “-ld.” a pronunciation difficulty for many non-native English speakers. His teacher, Thomas Whaley, is next to him, whispering support. “…Vote for…me…”Except for some stumbles.Chris is doing amazingly well. When he brings his speech to a nice conclusion, Whaley invites the rest of the class to praise him.A son of immigrants, Chris started learning English a little over three years ago. Whaley recalls(回想) how at the beginning of the year, when called upon to read, Chris would excuse himself to go to the bathroom.Learning English as a second language can be a painful experience. What you need is a great teacher who lets you make mistakes. “It takes a lot for any student,” Whaley explains, “especially for a student who is learning English as their new language, to feel confident enough to say, ‘I don’t know, but I want to know.’ ”Whaley got the idea of this second-grade presidential campaign project when he asked the children one day to raise their hands if they thought they could never be a president. The answer broke his heart. Whaley says the project is about more than just learning to read and speak in public. He wants these kids to learn to boast (夸耀) about themselves.“Boasting about you rself, and your best qualities,”Whaley says, is very difficult for a child who came into the classroom not feeling confident.”( ) 24. What made Chris nervous?A. Telling a story.B. Making a speech.C. Taking a test.D. Answering a question.( ) 25. What does the underlined word “stumbles” in paragraph 2 refer to?A. Improper pauses.B. Bad manners.C. Spelling mistakes.D. Silly jokes.( ) 26. We can infer that the purpose of Whaley’s project is to _______.A. help students see their own strengthsB. assess students’ public speaking skillsC. prepare students for their future jobsD. inspire students love for politics( ) 27. Which of the following best describes Whaley as a teacher?A. Humorous.B. Ambitious.C. Caring.D. DemandingCAs data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies--like fingerprint scans--to keep others out of private e-spaces. At present, these technologies are still expensive, though.Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key, The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to--regardless of whether someone gets the password right.It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.( ) 28. Why do the researchers develop the smart keyboard?A. To reduce pressure on keys.B. To improve accuracy in typingC. To replace the password system.D. To cut the cost of e-space protection.( ) 29. What makes the invention of the smart keyboard possible?A. Computers are much easier to operate.B. Fingerprint scanning techniques develop fast.C. Typing patterns vary from person to person.D. Data security measures are guaranteed.( ) 30. What do the researchers expect of the smart keyboard?A. It’ll be environment-friendly.B. It’ll reach consumers soon.C. I’ll be made of plastics.D. I t’ll help speed up typing.( ) 31. Where is this text most likely from?A. A diary.B. A guidebookC. A novel.D. A magazine.DDuring the rosy years of elementary schoo1(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.Popularity is well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status seekers. The likables’plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.Enviable as the cool kids may have seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those least liked in elementary school, are “most likely to engage(从事) in dangerous and risky behavior.”In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status based on student surveys (调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had those who were high in status. It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us.”Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date---sharing, kindness, openness---carry over to later years and make you better able to relate and connect with others.In analyzing his and other research, Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. “Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advanta ge,” he said.( ) 32. What sort of girl was the author in her early years of elementary school?A. Unkind.B. Lonely.C. Generous.D. Cool.( ) 33. What is the second paragraph mainly about?A. The classification of the popular.B. The characteristics of adolescents.C. The importance of interpersonal skills.D. The causes of dishonorable behavior.( ) 34. What did Dr. Prinstein’s study find about the most liked kids?A. They appeared to be aggressive.B. They tended to be more adaptable.C. They enjoyed the highest status.D. They performed well academically.( ) 35 What is the best title for the text?A. Be Nice---You Won’t Finish LastB. The Higher the Status, the BetterC. Be the Best---You Can Make ItD. More Self-Control, Less Aggressiveness根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项, 选项中有两项为多余选项.Is Fresh Air Really Good for You?We all grew up hearing people tell us to “go ou t and get some fresh air.” 36 According to recent studies, the answer is a big YES, if the air quality in your camping area is good.37 If the air you’re breathing is clean---which it would be if you’re away from the smog of cities---then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles (肌肉) and your brain.Recently, people have begun studying the connection between the natural world and healing(治愈). 38. In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood (情绪). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 39 It gives us a great feeling of peace.40 While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D---but still protect your skin---put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D.A. Fresh air cleans our lungs.B. So what are you waiting for?C. Being in nature refreshes us.D. Another side benefit of getting fresh air is sunlight.E. But is fresh air really as good for you as your mother always said?F. Just as importantly, we tend to associate fresh air with health care.G. All across the country, recovery centers have begun building Healing Gardens.第三部分语言知识运用(共两节, 满分45分)第一节(共20小题: 每小题1.5分, 满分30分)阅读下面短文, 从短文后各题所给的A, B, C和D四个选项中, 选出可以填入空白处的最佳选项。

我们很容易低估英国作家吉米·哈利。

他有着一种令人愉快的、可读的风格,有人认为这种风格任何人都可以模仿得来。

很多次我听到人们说:“我能写一本书,我只是没时间。

”说起来容易,做起来难。

然而与大家通常所想的不同,正如吉米·哈利所言,他在早年觉得“尝试写作游戏”并非易事。

显然,即便他极具写作天赋,哈利呈现给这个世界的作品也是经过多年的练习、重写、阅读并且经过润色之后才得以形成的。

与大多数作家一样,一路走来,吉米·哈利不得不经受多次的失望与拒绝,但是这一切更坚定了他获取成功的决心。

他生命中所取得的一切,都是依靠自己艰苦的努力所获得的。

他在文学领域的成功也不例外。

Starting next year, any guaranteed bonus of top executives could be delayed 10 yearsif their banks are under investigation for wrongdoing. The main purpose o f this “clawback” rule is to hold bankers accountable for harmful risk-taking and to restore public trust infinancial institution. Yet officials also hope for a much larger benefit: more long termdecision-making not only by banks but also bu all corporations, to build a stronger economyfor future generations.“Short-termism” or the desire for quick profits, has worsened in publicly tradedcompanies, says the Bank of England’s top economist. Andrew Haldane. He quotes a giant ofclassical economies, Alfred Marshall, in describing this financial impatience as acting like“Children who pick the plums out of their pudding to eat them at once” rather than pu them aside to be eaten last.The average time for holding a stock in both the United States and Britain, he notes, hasdropped from seven years to seven months in recent decades. Transient investors, whodemand high quarterly profits from companies, can hinder a firm’s efforts to invest in long-term research or to build up customer loyalty. This has b een dubbed “quarterlycapitalism”.In addition, new digital technologies have allowed more rapid trading of equities,quicker use of information, and thus shortens attention spans in financial markers.seems to be a predominance of short-term thinking at the expense of long-t erm investing,” said Commissioner Daniel Gallagher of the US Securities and Exchange Commission in speechthis week.In the US, the Sarbanes-Oxley Act of 2002 has pushed most public companies to defer performance bonuses for senior executives by about a year, slightly helping reduce“short-termism.” In its latest survey of CEO pay, The Wall Street Journal finds thatsubstantial part” of executive pay is now tied to performance.-termism,” such as changes in the tax Much more could be done to encourage “longcode and quicker disclosure of stock acquisitions. In France, shareholders who hold onto acompany investment for at least two years can sometimes earn more voting rights in acompany.Within companies, the right compensation design can provide incentives for executivesto think beyond their own time at the company and on behalf of all stakeholders. Britainnew rule is a reminder to bankers that society has an interest in their performance, not justfor the short term but for the long term.21. According to Paragraph 1, one motive in imposing the new rule is the_________.A. enhance banker’s sense of responsibilityB. help corporations achieve larger profitsC. build a new system of financial regulationD. guarantee the bonuses of top executives22.

Which of the following would be the best title for the textA. Failure of Quarterly CapitalismB. Patience as a Corporate VirtueC. Decisiveness Required of Top ExecutivesD. Frustration of Risk-taking BankersText 2Grade inflation--the gradual increase in average GPAs(grade-point averages) over thepast few decades —is often considered a product of a consumer era in higher education, inwhich students are treated like customers to be pleased. But another, related force —a policyoften buried deep in course catalogs called “grade forgiveness ”—is helping raise GPAs.Grade forgiveness allows students to retake a course in which they received a low grade,and the most recent grade or the highest grade is the only one that counts in calculating astudent’s overall GPA.The use of this little-known practice has accelerated in recent years, as colleges continueto do their utmost to keep students in school (and paying tuition) and improve theirgraduation rates. When this practice first started decades ago, it was usually limited tofreshmen, to give them a second chance to take a class in their first year if they struggled intheir transition to college-level courses. But now most colleges save for many selectivecampuses, allow all undergraduates, and even graduate students, to get their low gradesforgiven.College officials tend to emphasize that the goal of grade forgiveness is less about thegrade itself and more about encouraging students to retake courses critical to their degreeprogram and graduation without incurring a big penalty. “Untimely,” said Jack Miner, Ove more success because they retake aState University’s registrar,“we see students achiecourse and do better in subsequent contents or master the content that allows them tograduate on time.”That said, there is a way in which grade forgiveness satisfies colleges’ own ne For public institutions, state funds are sometimes tied partly to their success on metrics suchas graduation rates and student retention—so better grades can, by boosting figures likethose, mean more money. And anything that raises GPAs will likely make students—who, atthe end of the day, are paying the bill—feel they’ve gotten a better value for their tuitiondollars, which is another big concern for colleges.Indeed, grade forgiveness is just another way that universities are responding tor education. Since students and parents expect a collegeconsumers’ expectations for highedegree to lead a job, it is in the best interest of a school to turn out graduates who are asqualified as possible—or at least appear to be. On this, students’ and colleges’ incenti seem to be aligned.26. What is commonly regarded as the cause of grade inflationA. The change of course catalogs.B. Students’ indifference to GPAS.C. Colleges’ neglect of GPAS.D. The influence of consumer culture.27. What was the original purpose of grade forgivenessA. To help freshmen adapt to college learning.B. To maintain colleges’ graduation rates.C. To prepare graduates for a challenging future.D. To increase universities’ income from tuition.28. According to Paragraph 5,grade forgiveness enable colleges to_________.A. obtain more financial supportB. boost their student enrollmentsC. improve their teaching qualityD. meet local governments’ needs29. What does the phrase “to be aligned”(Line 5,most probably meanA. To counterbalance each other.B. To complement each other.C. To be identical with each other.D. To be contradictory to each other.30. The author examines the practice of grade forgiveness by________.A. assessing its feasibilityB. analyzing the causes behind itC. comparing different views on itD. listing its long-run effectsText 3This year marks exactly two countries since the publication of Frankenstein; or, The Modern Prometheus, by Mary Shelley. Even before the invention of the electric light bulb, the author produced a remarkable work of speculative fiction that would foreshadow many ethical questions to be raised by technologies yet to come.Today the rapid growth of artificial intelligence (AI) raises fundamental questions:is intelligence, identify, orconsciousness What makes humans humans”What is being called artificial general intelligence, machines that would imitate the wayhumans think, continues to evade scientists. Yet humans remain fascinated by the idea ofrobots that would look, move, and respond like humans, similar to those recently depictedon popular sci-fi TV series such as “Westworld” and “Humans”.Just how people think is still far too complex to be understood, let alone reproduced,n a situation wheresays David Eagleman, a Stanford University neuroscientist. “We are just ithere are no good theories explaining what consciousnesss actually is and how you couldever build a machine to get there.”But that doesn’t mean crucial ethical issues involving AI aren’t at hand. The com of autonomous vehicles, for example, poses thorny ethical questions. Human driverssometimes must make split-second decisions. Their reactions may be a complex combinationof instant reflexes, input from past driving experiences, and what their eyes and ears tellthem in that mo ment. AI “vision” today is not nearly as sophisticated as that of humans. Andto anticipate every imaginable driving situation is a difficult programming problem.Whenever decisions are based on masses of data, “you quickly get into a lot of ethical questions,” notes Tan Kiat How, chief executive of a Singapore-based agency that is helpingthe government develop a voluntary code for the ethical use of AI. Along with Singapore,other governments and mega-corporations are beginning to establish their own guidelines.Britain is setting up a data ethics center. India released its AI ethics strategy this spring.On June 7 Google pledged not to “design or deploy AI” that would cause “overa or to develop AI-directed weapons or use AI for surveillance that would violate internationalnorms. It also pledged not to deploy AI whose use would violate international laws or humanrights.While the statement is vague, it represents one starting point. So does the idea thatdecisions made by AI systems should be explainable, transparent, and fair.To put it another way: How can we make sure that the thinking of intelligent machinesreflects humanity’s highest values Only then will they be useful servants and not-of-control monster.Frankenstein’s out31. Mary Shelley’s novel Frankenstein is mentioned because itA. fascinates AI scientists all over the world.B. has remained popular for as long as 200 years.C. involves some concerns raised by AI today.D. has sparked serious ethical controversies.32. In David Eaglema n’s opinion, our current knowledge of consciousnessA. helps explain artificial intelligence.B. can be misleading to robot making.C. inspires popular sci-fi TV series.D. is too limited for us to reproduce it.33. The solution to the ethical issues brought by autonomous vehiclesA. can hardly ever be found.B. is still beyond our capacity.C. causes little public concern.D. has aroused much curiosity.34. The author’s attitude toward Google’s pledge is one ofA. affirmation.B. skepticism.C. contempt.D. respect.35. Which of the following would be the best title for the textA. AI’s Future: In the Hands of Tech GiantsB. Frankenstein, the Novel Predicting the Age of AIC. The Conscience of AI: Complex But InevitableD. AI Shall Be Killers Once Out of ControlText 4States will be able to force more people to pay sales tax when they make online purchases under a Supreme Court decision Thursday that will leave shoppers with lighter wallets but is a big financial win for states.Thursday overruled a pair of decades-old decisions that The Supreme Court’s opinionstates said cost them billions of dollars in lost revenue annually. The decisions made it moredifficult for states to collect sales tax on certain online purchases.The cases the court overturned sai d that if a business was shipping a customer’s purchase to a state where the business didn’t have a physical presence such as a warehouse or office, the business didn’t have to collect sales tax for the state. Customers were generally responsible for paying the sales tax to the state themselves if they weren’t charged it, bu most didn’t realize they owed it and few paid.Justice Anthony Kennedy wrote that the previous decisions were flawed. “Each ye physical presence rule becomes further removed from economic reality and results insignificant revenue losses to the States,” he wrote in an opinion joined by four other justices.-term prosperity and hasKennedy wrote that the rule “limited states’ ability to seek longprevented market participants from competing on an even playing field.”The ruling is a victory for big chains with a presence in many states, since they usuallycollect sales tax on online purchases already. Now, rivals will be charging sales tax where theyen collecting sales tax nationwide because they typicallyhadn’t before. Big chains have behave physical stores in whatever state a purchase is being shipped to. , with its network of warehouses, also collects sales tax in every state that charges it, though third-party sellerswho use the site don’t have to.Until now, many sellers that have a physical presence in only a single state or a fewstates have been able to avoid charging sales taxes when they ship to addresses outsidethose states. Sellers that use eBay and Etsy, which provide platforms for smaller sellers, alsohaven’t been collecting sales tax nationwide. Under the ruling Thursday, states can pass lawsrequiring out-of-state sellers to collect the state’s sales tax from customers and send it to the state.Retail trade groups praised the ruling, saying it levels the playing field for local andonline businesses. The losers, said retail analyst Neil Saunders, are online-only retailers,especially smaller ones. Those retailers may face headaches complying with various statesales tax laws.

In dealing with the Supreme Court decision Thursday, the authorA. gives a factual account of it and discusses its consequencesB. describes the long and complicated process of its makingC. presents its main points with conflicting views on themD. cities some saces related to it and analyzes their implicationsPart BDirections:The following paragraphs are given in a wrong order. For Questions 41-45, you arerequired to reorganize these paragraphs into a coherent article by choosing from the listA-G and filling them into the numbered boxes. Paragraph C and F have been correctlyplaced. Mark your answers on ANSWER SHEET. (10 points)A. These tools can help you win every argument-not in the unhelpful sense of beatingyour opponents but in the better sense of learning about the issues that divide people.Learning why they disagree with us and learning to talk and work together with them. If wereadjust our view of arguments—from a verbal fight or tennis game to a reasoned exchangethrough which we all gain mutual respect, and understanding—then we change the verynature of what it means to “win” an argument.B. Of course, many discussions are not so successful. Still, we need to be careful not toaccuse opponents of bad arguments too quickly. We need to learn how to evaluate themproperly. A large part of evaluation is calling out bad arguments, but we also need to admitgood arguments by opponents and to apply the same critical standards to ourselves. Humilityrequires you to recognize weakness in your own arguments and sometimes also to acceptreasons on the opposite side.C. None of these will be easy but you can start even if others refuse to. Next time youstate your position, formulate an argument for what you claim and honestly ask yourselfwhether your argument is any good. Next time you talk with someone who takes a stand, askthem to give you a reason for their view. Spell out their argument fully and charitably. Assessits strength impartially. Raise objections and listen carefully to their replies.D. Carnegie would be right if arguments were fights, which is how we often think ofthem. Like physical fights, verbal fights can leave both sides bloodied. Even when you win,you end up no better off. Your prospects would be almost as dismal if arguments were evenjust competitions-like, say, tennis games. Paris of opponents hit the ball back and forth untilone winner emerges from all who entered. Everybody else loses. This kind of thinking is whyso many people try to avoid arguments, especially about politics and religion.E. In his 1936 work How to Win Friends and Influence People , Dale Carnegie wrote:“there is only one way…to get thebest of an argument-and that is to avoid it. “This aversion to arguments is common, but it depends on a mistaken view of arguments that causes profound problems for our personaland social lives- and in many ways misses the point of arguing in the first place.F. These views of arguments also undermine reason. If you see a conversation as a fightor competition, you can win by cheating a s long as you don’t get caught. You will be happy to convince people with bad arguments. You can call their views stupid, or joke about howignorant they are. None of these tricks will help you understand them, their positions or theissues that divide you, but they can help you win-in one way.G. There is a better way to win arguments. Imagine that you favor increasing theminimum wage in our state, and I do not. If you yell, “yes,” and I yell. “No,” n learns anything. We neither understand nor respect each other, and we have no basis forcompromise or cooperation. In contrast, suppose you give a reasonable argument: thatfull-time workers should not have to live in poverty. Then I counter with another reasonableargument: that a higher minimum wage will force businesses to employ fewer people for lesstime. Now we can understand each other’s positions and recognize our shared values, sincewe both care about needy workers.41→42→F→43→44→C→45Part CDirections:Read the following text carefully and then translate the underlined segments intoChinese. Your translation should be written neatly on the ANSWER SHEET. (10 points) It was only after I started to write a weekly column about the medical journals, andbegan to read scientific papers from beginning to end, that I realised just how bad much ofthe medical literature frequently was. I came to recognise various signs of a bad paper: thekind of paper that purports to show that people who eat more than one kilo of broccoli aweek were times more likely than those who eat less to suffer late in life from perniciousanaemia. (46) There is a great deal of this kind of nonsense in the medical journals which,when taken up by broadcasters and the lay press, generates both health scares andshort-lived dietary enthusiasms.Why is so much bad science published A recent paper, titled “The Natural Selection Bad Science”, published on the Royal Society’s open science website, attempts to answer th intriguing and important question. It says that the problem is not merely that people do badscience, but that our current system of career advancement positively encourages it. What isimportant is not truth, but publication, which has become almost an end in itself. There hasbeen a kind of inflationary process at work: (47) nowadays anyone applying for a researchpost has to have published twice the number of papers that would have been required forthe same post only 10 years ago. Never mind the quality, then, count the number.(48) Attempts have been made to curb this tendency, for example, by trying toincorporate some measure of quality as well as quantity into the assessment of an applicantpapers. This is the famed citation index, that is to say the number of times a paper has beenquoted elsewhere in the scientific literature, the assumption being that an important paperwill be cited more often than one of small account. (49) This would be reasonable if it werenot for the fact that scientists can easily arrange to cite themselves in their futurepublications, or get associates to do so for them in return for similar favours.Boiling down an individual’s output to simple metrics, such as number of publications or journal impacts, entails considerable savings in time, energy and ambiguity. Unfortunately,the long-term costs of using simple quantitative metrics to assess researcher merit are likelyto be quite great. (50) If we are serious about ensuring that our science is both meaningfuland reproducible, we must ensure that our institutions encourage that kind of science.Section Ⅲ WritingPart A51.

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked [A], [B], [C], and [D]. You should decide on the best choice and mark the corresponding letter on the Answer Sheet 1 with a single line through the center.Passage OneQuestions 36 to 40 are based on the following passage.Three Yale University professors agreed in a panel discussion tonight that the automobile was what one of them called “Public Health Enemy No.1 in this country.” Besides polluting the air and congesting the cities, cars are involved in more than half the disabling accidents, and they cause heart disease “because we don’t walk anywhere anymore,” said Dr. H. Richard Weinerman, professor of medicine and public health. Dr. Weinerman’s sharp criticism of automobile came in a discussion of human environment on Yale Reports, a radio program broadcast by Station WTIC in Hartford, Connecticut. The program opened a three-part series on “Staying Alive.” “For the first time in human history, the problem of man’s survival has to do wi th his control of man-made dangers,” Dr. Weinerman said. “Before this, the problem had been the control of natural dangers.”Relating many of these dangers of the automobile, Arthur W. Galston, a professor of biology, said it was possible to make a kerosene-burning car that would “lessen smog by a very large factor.” But he expressed doubt that Americans were willing to give up moving about the countryside at 90 miles an hour in a large vehicle. “America seems wedded to the motor car - every family has to h ave at least two, and one has to be a convertible with 300 horsepower,” Professor Galston continued. “Is this the way of life that we choose because we cherish these values?”For Paul B. Sears, professor of conservation, part of the blame lies with “a soci ety that regards profit as a supreme value, under the false idea that anything that’s technically possible is, therefore, ethically justified.” Professor Sears also called the country’s dependence on its modern automobile “lousy economics” because of the large horsepower used simply “moving one person to work.” But he agreed that Americans have painted themselves into a corner by allowing the national economy to become so reliant on the automobile industry.According to Dr. Weinerman, automobiles, not the factories, are responsible for two-thirds of the smog in American cities, and the smog presents the possibility of a whole new kind of epidemic, not due to one germ, but due to polluted environment. “Within another five to ten years, it’s possible to have an epidemic of lung cancer in a city like Los Angeles. This is a new phenomenon in health concern,” he said.The solution, he continued, is “not to find a less dangerous fuel, but a different system of inner-city transportation. Because of the increasing use of cars, public transportation has been allowed to wither and degenerate, so that if you can’t walk to where you want to go, you have to have a car in most cities,” he asserted. This, in turn, Dr. Weinerman contended, is responsible for the “arteriosclerosis” of public roads, for the blight of the inner city and for the middle-classmovement to the suburbs.31. The main idea of this article is that _______.[A] Americans are too attached to their cars.[B] American cars run too fast and consume too much fuel.[C] the automobile industry has caused all this to happen.[D] automobiles endanger both the environment and people.32. In paragraph 2, Professor Galston implies that _______.[A] people are more interested in fast automobiles than in their health.[B] kerosene-burning cars would pollute the environment more seriously thangasoline-burning engines do.[C] Americans feel more closely connected to their cars than to the environment.[D] it is not right for every family to have at least two cars.33. In paragraph 3, Professor Sears implies that _______.[A] technology is always good for people.[B] technology is not always good for people.[C] financial profit is more important than technological advancement.[D] technological advancement will improve financial profit.34. It can be inferred from Paragraph 5 that _______.[A] a fuel less dangerous than gasoline must be found.[B] people should get rid of their cars and take the bus to work.[C] public transportation should be improved so that people can become less dependent upontheir cars for inner-city transportation.[D] the only solution to this problem is to build more high ways and more subways.35. Dr. Weinerman would probably agree that _______, if public transportation were improved.[A] the inner city might improve[B] the middle class would move to the suburbs[C] public roads would get worse[D] there would still be an urgent need to build more highwaysPassage TwoQuestions 31 to 35 are based on the following passage.The Food and Drug Administration said on Wednesday that it is trying to track down as many as 386 piglets that may have been genetically engineered and wrongfully sold into the U.S. food supply.The focus of the FDA investigation is on pigs raised by researchers at the University of Illinois in Urbana Champaign. They engineered the animals with two genes: one is a cow gene that increases milk production in the sow; the other, a synthetic gene, makes the milk easier for piglets to digest. The goal was to raise bigger pigs faster.There has been no evidence that either genetically altered plants or animals actually trigger human illness, but critics warn that potential side effects remain unknown. University officials say their tests showed the piglets were not born with the altered genes, but FDA rules require even the offspring of genetically engineered animals to be destroyed so they won’t get into the food supply. The FDA, in a quickly arranged news conference on Wednesday prompted by inquiries by USA TODAY, said the University of Illinois would face possible sanctions and fines for selling the piglets to a livestock broker, who in turn sold them to processing plants.Both the FDA and the university say the pigs that entered the market do not pose a risk to consumers. But the investigation follows action by the U.S. Department of Agriculture in December to fine a Texas company that contaminated 500,000 bushels of soybeans with corn that had been genetically altered to produce a vaccine for pigs.Critics see such cases as evidence of the need for more government oversight of a burgeoning(新兴的)area of scientific research. “This is a small incident, but it’s incidents like this that could destroy consumer confidence and export confidence,” says Stephanie Childs of the Grocery Manufacturers of America. “We already have Europe shaky on biotech. The countries to which we export are going to look at this.”The University of Illinois says it tested the DNA of every piglet eight times to make sure that the animal hadn’t inherited the genetic engineering of its mother. Those piglets that did were put back into the study. Those that didn’t were sold to the pig broker. “Any pig that was tested negative for the genes since 1999 has been sent off to market,” says Charles Zukoski, vice chan cellor for research.But FDA deputy commissioner Lester Crawford says that under the terms of the university’s agreement with the FDA, the researchers were forbidden to remove the piglets without FDA approval. “The University of Illinois failed to check wi th FDA to see whether or not the animals could be sold on the open market. And they were not to be used under any circumstance for food.”The FDA is responsible for regulating and overseeing transgenic animals because such genetic manipulation is considered an unapproved animal drug.36. The 386 piglets wrongfully sold into food supply are from ________.[A] Europe[B] an American research organization[C] a meat processing plant[D] an animal farm37. The purpose of the transgenic engineering research is to ________.[A] get pigs of larger size in a shorter time[B] make sows produce more milk[C] make cows produce more milk[D] make pigs grow more lean meat38. The 4th paragraph shows that the University of Illinois ________.[A] was criticized by the FDA[B] is in great trouble[C] is required by the FDA to call back the sold piglets[D] may have to pay the penalty39. The FDA declares that the wrongfully sold piglets ________.[A] may have side effects on consumers[B] may be harmful to consumers[C] are safe to consumers[D] may cause human illness40. It can be inferred from this passage that ________.[A] all the offspring have their mothers’ genetic engineering[B] part of the offspring have their mothers’ genetic engineering[C] none of the of fspring have their mothers’ genetic engineering[D] half of the offspring have their mothers’ genetic engineeringPart III: English Writing (15%)DIRECTIONS: For this part, you are going to write a short essay on the title.

(10 points)Weighing yourself regularly is a wonderful way to stay aware of any significant weight fluctuations.1, when done too often, this habit can sometimes hurt more than it2.As for me, weighing myself every day caused me to shift my focus from being generally healthy and physically active to focusing3on the scale.

Mark your answers on the ANSWER SHEET. (40 points)Text 1Unlike so-called basic emotions such as sadness, fear, and anger, guilt emerges a little later, in conjunction with a child’s growing grasp of social and moral norms. Children aren’t born knowing how to say“I’m sorry”; rather, they learn over time that such statements appease parents and friends—and their own consciences. This is why researchers generally regard so-called moral guilt, in the right amount, to be a good thing.In the popular imagination, of course, guilt still gets a bad rap. It is deeply uncomfortable—it’s the emotional equivalent of wearing a jacket weighted with stones. Yet this understanding is outdated.“There has been a kind of revival or a rethinking about what guilt is and what role guilt can serve,”says Amrisha Vaish, a psychology researcher at the University of Virginia, adding that this revival is part of a larger recognition that emotions aren’t binary—feelings that may be advantageous in one context may be harmful in another. Jealousy and anger, for example, may have evolved to alert us to important inequalities. Too much happiness can be destructive.And guilt, by prompting us to think more deeply about our goodness, can encourage humans to make up for errors and fix relationships. Guilt, in other words, can help hold a cooperative species together. It is a kind of social glue.Viewed in this light, guilt is an opportunity. Work by Tina Malti, a psychology professor at the University of Toronto, suggests that guilt may compensate for an emotional deficiency. In a number of studies, Malti and others have shown that guilt and sympathy may represent different pathways to cooperation and sharing. Some kids who are low in sympathy may make up for that shortfall by experiencing more guilt, which can rein in their nastier impulses. And vice versa: High sympathy can substitute for low guilt.In a 2014 study, for example, Malti looked at 244 children. Using caregiver assessments and the children’s self-observations, she rated each child’s overall sympathy level and his or her tendency to feel negative emotions after moral transgressions. Then the kids were handed chocolate coins, and given a chance to share them with an anonymous child. For the low-sympathy kids, how much they shared appeared to turn on how inclined they were to feel guilty. The guilt-prone ones shared more, even though they hadn’t magically become more sympathetic to the other child’s deprivation.“That’s good news,”Malti says.“We can be prosocial because we caused harm and we feel regret.”21.Researchers think that guilt can be a good thing because it may help______.A)regulate a child's basic emotionsB)improve a child's intellectual abilityC)foster a child’s moral developmentD)intensity a child's positive feelings22.According to paragraph 2, many people still consider guilt to be______.A)deceptiveB)burdensomeC)addictiveD) deception23. Vaish hold that the rethinking about guilt comes from an awareness that______.A)emotions are context-independentB)emotions are socially constructiveC)emotional stability can benefit healthD)an emotion can play opposing roles24. Malti and others have shown that cooperation and sharing _______.A. may help correct emotional deficienciesB. can result from either sympathy or guiltC. can bring about emotional satisfactionD. may be the outcome of impulsive acts25. The word “transgressions”(Line 4, Para.5) is closest in meaning to _______.A. teachingsB. discussionsC. restrictionsD. wrongdoingsText 2Forests give us shade, quiet and one of the larder callenges in the fight against climate change. Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we are threatening their ability to do so. The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.Thankfully, there is a way out of this trap-but it involves striking a subtle balance. Helping forests flourish as valuable “carbon sinks”long into the future may require reducing their capacity to absorb carbon now. California is leading the way, as it does on so many climate efforts, in figuring out the details.The state’s proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest. This temporarily lowers carbon-carrying capacity. But the remaining trees draw a greater share of the available moisture, so they grow and thrive, restoring the forest’s capacity to pull carbon from the air. Healthy trees are also better able to fend off insects. The landscape is rendered less easily burnable. Even in the event of a fine, fewer trees are consumed.The need for such planning is increasingly urgent. Already, since 2010, drought and insects have killed over 100 million trees in California, most of them in 2016 alone, and wildfires have burned hundreds of thousands of acres.California plans to treat 35,000 acres of forest a year by 2020, and 60,000 by 2030- financed from the proceeds of the state’s emissions-permit auctions. That’s only a small share of the total acreage that could benefit, about half a million acres in all, so it will be vital to prioritize areas at greatest risk of fire or drought.The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels. New research on transportation biofuels is already under way.State governments are well accustomed to managing forests, but traditionally they’ve focused on wildlife, watersheds and opportunities for recreation. Only recently have they come to see the vital part forests will have to play in storing carbon. California’s plan, which is expected to be finalized by the governor next year, should serve as a model.26. By saying “one of the harder challenges,”the author implies that _______.A. global climate change may get out of controlB. people may misunderstand global warmingC. extreme weather conditions may ariseD. forests may become a potential threat27. To maintain forests as valuable “carbon sinks,”we may need to _______.A. preserve the diversity of species in themB. accelerate the growth of young treesC. strike a balance among different plantsD. lower their present carbon-absorbing capacity28. California’s Forest Carbon Plan endeavors to _______.A. cultivate more drought-resistant treesB. reduce the density of some of its forestsC. find more effective ways to kill insectsD. restore its forests quickly after wildfires29. What is essential to California’s plan according to Paragraph 5?A.To handle the areas in serious danger first.B.To carry it out before the year of 2020.C.To perfect the emissions-permit auctions.D.To obtain enough financial support.30. The author’s attitude to California’s plan can best be described as _______.A. ambiguousB. tolerantC. supportiveD. cautiousText 3American farmers have been complaining of labor shortages for several years. The complaints are unlikely to stop without an overhaul of immigration rules for farm workers.Congress has obstructed efforts to create a more straightforward visa for agricultural workers that would let foreign workers stay longer in the U.S. and change jobs within the industry. If this doesn’t change, American businesses, communities, and consumers will be the losers.Perhaps half of U.S. farm laborers are undocumented immigrants. As fewer such workers enter the country, the characteristics of the agricultural workforce are changing. Today’s farm laborers, while still predominantly born in Mexico, are more likely to be settled rather than migrating and more likely to be married than single. They’re also aging. At the start of this century, about one-third of crop workers were over the age of 35. Now more than half are. And picking crops is hard on older bodies. One oft-debated cure for this labor shortage remains as implausible as it’s been all along: Native U.S. workers won’t be returning to the farm.Mechanization isn’t the answer, either—not yer, at least. Production of corn, cotton, rice, soybeans, and wheat has been largely mechanized, but many high-value, labor-intensive corps,such as strawberries, need labor. Even dairy farms, where robots do a small share of milking, have a long way to go before they’re automated.As a result, farms have grown increasingly reliant on temporary guest workers using the H-2A visa to fill the gaps in the workforce. Starting around 2012, requests for the visas rose sharply; from 2011 to 2016 the number of visas issued more than doubled.The H-2A visa has no numerical cap, unlike the H-2B visa for nonagricultural work, which is limited to 66,000 a year. Even so, employers complain they aren’t given all the workers they need. The process is cumbersome, expensive, and unreliable. One survey found that bureaucratic delays led the average H-2A worker to arrive on the job 22 days late. The shortage is compounded by federal immigration raids, which remove some workers and drive others underground.In a 2012 survey, 71 percent of tree-fruit growers and almost 80 percent of raisin and berry growers said they were short of labor. Some western farmers have responded by moving operations to Mexico. From 1998 to 2000, 14.5 percent of the fruit Americans consumed was imported. Little more than a decade later, the share of imports was 25.8 percent.In effect, the U.S. can import food or it can import the workers who pick it.31. What problem should be addressed according to the first two paragraphs?A. Discrimination against foreign workers in the U.S.B. Biased laws in favor of some American businesses.C. Flaws in U.S. immigration rules for farm workers.D. Decline of job opportunities U.S. agriculture.32. One trouble with U.S. agricultural workforce is .A. the rising number of illegal immigrantsB. the high mobility of crop workersC. the lack of experienced laborersD. the aging of immigrant farm workers33.What is the much-argued solution to the labor shortage in U.S. farming?A. To attract younger laborers to farm work.B. To get native U.S. workers back to farming.C. To use more robots to grow high-value crops.D. To strengthen financial support for farmers.34. Agricultural employers complain about the H-2A visa for its .A. slow granting proceduresB. limit on duration of stayC. tightened requirementsD. control of annual admissions35. Which of the following could be the best title for this text?A. U.S. Agriculture in Decline?B. Import Food or Labor?C. America Saved by Mexico?D. Manpower vs. Automation?Text 4Amold Schwarzenegger. Dia Mirza and Adrian Grenier have a message for you. It’s easy to beat plastic. They’re part of a bunch of celebrities starring in a new video for World EnvironmentDay—encouraging you, the consumer, to swap out your single-use plastic staples like straws and cutlery to combat the plastics crisis.The key messages that have been put together for World Environment Day do include a call for governments to enact legislation to curb single-use plastics. But the overarching message is directed at individuals.My concern with leaving it up to the individual, however, is our limited sense of what needs to be achieved. One their own, taking our own bags to the grocery store or quitting plastic straws, for example, will accomplish little and require very little of us. They could even be detrimental, satisfying a need to have “done our bit”without ever progressing onto bigger, bolder, more effective actions—a kind of“moral licensing”that allays our concerns and stops us doing more and asking more of those in charge.While the conversation around our environment and our responsibility toward it remains centered on shopping hags and straws, we’re ignoring the balance of power that implies that as“consumers”we must shop sustainably, rather than as“citizens”hole our governments and industries to account to push for real systemic change.It’s important to acknowledge that the environment isn’t everyone’s priority-or even most people’s. We shouldn’t expect it to be. In her latest book, Why Good People Do Bad Environmental Things. Wellesley College professor Elizabeth R. DeSombre argues that the best way to collectively change the behavior of large numbers of people is for the change to be structural.This might mean implementing policy such as a plastic tax that adds a cost to environmentally problematic action, or banning single-use plastics altogether. India has just announced it will “eliminate all single-use plastic in the country by 2022.”There are also incentive-based ways of making better environmental choices easier, such as ensuring recycling is at least as easy as trash disposal.DeSombre isn’t saying people should stop caring about the environment. It’s just that individual actions are too slow, she says, for that to be the only, or even primary, approach to changing widespread behavior.None of this is about writing off the individual. It’s just about putting things into perspective. We don’t have time to wait. We need progressive policies that shape collective action (and rein in polluting businesses), alongside engaged citizens pushing for change.36. Some celebrities star in a new video toA. demand new laws on the use of plasticsB. urge consumers to cut the use of plasticsC. invite public opinion on the plastics crisisD. disclose the causes of the plastics crisis37.The author is concerned that “moral licensing”mayA. mislead us into doing worthless thingsB. prevent us from making further effortsC. weaken our sense of accomplishmentD. suppress our desire for success38. By pointing out out identity “citizens”, the author indicates thatA. our focus should be shifted to community welfareB. our relationship with local industries is improvingC. We have been actively exercising our civil rightsD. We should press our government to lead the combat39. DeSombre argues that the best way for a collective change should beA. a win-win arrangementB. a self-driven mechanismC. a cost-effective approachD. a top down process40. The author concludes that individual effortsA.can be too aggressiveB. can be too inconsistentC. are far from sufficientD. are far from rationalPart BDirections:You are going to read a list of headings and a text.

Mark your answers on the ANSWER SHEET.(10 points) Five ways to make conversation with anyoneIn choosing a new home, Camille McClain’s kids have single demand: a backyard.McClain’s little one aren’t the only kids who have an opinion when it comes to housing, and in many cases youngsters’views weigh heavily on parents’real estate decisions, according to a 2018 Harris Poll survey of more than 2,000 U.S. adults.While more families buck an older-generation proclivity to leave kids in the dark about real estate decisions, realty agents and psychologists have mixed views about the financial, personal and long-term effects kids’opinions may have.The idea of involving children in a big decision is a great idea because it can help them feel a sense of control and ownership in what can be an overwhelming process, said Ryan Hooper, clinical psychologist in Chicago.“Children may face serious difficulties in coping with significant moves, especially if it removes them from their current school or support system,”he said.Greg Jaroszewski, a real estate brokers with Gagliardo Realty Associates, said he’s not convinced that kids should be involved in selecting a home—but their opinions should be considered in regards to proximity to friends and social activities, if possible.Younger children should feel like they’re choosing their home—without actually getting a choice in the matter, said Adam Bailey, a real estate attorney based in New York.Asking them questions about what they like about the backyard of a potential home will make them feel like they’re being included in the decision-making process, Bailey said.Many of the aspects of homebuying aren’t a consideration for children, said Tracey Hampson, a real estate agent based in Santa Clarita, Calif. And placing too much emphasis on their opinions can ruin a fantastic home purchase.“Speaking with your children before you make a real estate decision is wise, but I wouldn’t base the purchasing decision solely on their opinions.”Hampson said.The other issue is that many children-especially older ones-may base their real estate knowledge on HGTV shows, said Aaron Norris of The Norris Group in Riverside, Calif.“They love Chip and Joanna Gaines just as much as the rest of us,”he said.“HGTV has seriouslychanged how people view real estate. It’s not shelter, it’s a lifestyle. With that mindset change come some serious money consequences.”Kids tend to get stuck in the features and the immediate benefits to them personally, Norris said. Parents need to remind their children that their needs and desires may change over time, said Julie Gurner, a real estate analyst with .“Their opinions can change tomorrow,”Gurner said.“Harsh as it may be to say, that decision should likely not be made contingent on a child’s opinions, but rather made for them with great consideration into what home can meet their needs best-and give them an opportunity to customize it a bit and make it their own.”This advice is more relevant now than ever before, even as more parents want to embrace the ideas of their children, despite the current housing crunch.A.remarks that significant moves may pose challenges to children.41.Ryan Hooper B.says that it is wise to leave kids in the dark about real estate decisions.42.

He had such a pleasant, readable style that one might think that anyone could imitate it. How many times have I heard people say “I could write a book. I just haven’t the time.”Easily said. Not so easily done. James Herriot, contrary to pupular opinion, did not find it easy in his early days of, as he put it,“having a go at the writing game”. While he obviously had an abundance of natural talent, the final, polished work that he gave to the world was the result of years of practising, re-writing and reading. Like the majority of authors, he had to suffer many disappointments and rejections along the way, but these made him all the more determined to succeed.

It is also the closest planet to earth,and thus the most similar in distance from the sun.In short, Venus seems to justify its long-held nickname of“earth’s twin.”The surface temperature of Venus reaches some900F.Added to that is an atmospheric pressure about90times Earth’s:High overhead in the carbon dioxide(CO2)that passes for air is a layer of clouds,perhaps10to20miles thick,whose little drops consist mostly of sulfuric acid (H2SO4).Water is all but nonexistent.Born with so many fundamental similarities to earth,how did Venus get to be so radically different:It is not just an academic matter.For all its extremes,Venus is a valuable laboratory for researchers studying the weather and climate of earth.It has no earth’s oceans,so the heat transport and other mechanisms are greatly simplified.In addition,the planet Venus takes243 earth-days to turn once on its axis,so incoming heat from the sun is added and distributed at a more leisurely,observable pace.16.Venus is similar to Earth in________.[A]size and density[B]distance from the sun[C]having atmosphere[D]all of the above17.The greatest value in studying Venus should be to________.[A]allow us to visit there[B]understand Earth better[C]find a new source of energy[D]promote a new space program18.The main idea of this passage is about________.[A]problems of space travel[B]scientific methods in space exploration[C]the importance of Venus to Earth[D]conditions on VenusText2Tourists were surprised to see a woman driving a huge orange tractor down one of Rome’s main avenues.Italy’s political leaders and some of its male union chiefs are said to have beeneven more puzzled to see that the tractor was followed by about200,000women in a parading procession that took more than three hours to snake through central Rome.Shouting slogans,waving flags and dancing to drumbeats,the women had come to the capital from all over Italy to demonstrate for“a job for each of us,a different type of job,and a society without violence.”So far,action to improve women’s opportunities in employment has been the province of collective industrial bargaining.“But there is a growing awareness that this is not enough,”says a researcher on female labor at the government-funded Institute for the Development of Professional Training for Workers.Women,who constitute52per cent of Italy’s population,today represent only35per cent of Italy’s total workforce and33per cent of the total number of Italians with jobs.However,their presence in the workplace is growing.The employment of women is expanding considerably in services,next to the public administration and commerce as their principal workplace.Official statistics also show that women have also made significant strides in self-employment.More and more women are going into business for themselves.Many young women are turning to business because of the growing overall in employment.It is also a fact that today many prejudices have disappeared,so that banks and other financial institutes make judgments on purely business considerations without caring if it is a man or a woman.Such changes are occurring in the professions too.The number of women doctors,dentists, lawyers,engineers and university professors increased two to three fold.Some of the changes are immediately visible.For example,women have appeared on the scene for the first time as state police,railway workers and street cleaners.However,the present situation is far from satisfactory though some progress has been made.A breakthrough in equal opportunities for women is now demanded.19.The expression“snake through central Rome”probably means“to move________[A]quietly through central Rome.”[B]violently through central Rome.”[C]in a long winding line through central Rome.”[D]at a leisurely pace through central Rome.”20.Which of the following statements is NOT true?[A]There are more women than men in Italy.[B]In Italy,women are chiefly employed in services.[C]In Italy,women are still at a disadvantage in employment.[D]In Italy,about two-thirds of the jobs are held by men.21.About200,000women in Rome demonstrated for________.[A]more job opportunities[B]a greater variety of jobs[C]“equal job,equal pay”[D]both A and B22.The best title for this passage would be________.[A]The Role of Women is Society[B]Women Demonstrate for Equality in Employment[C]Women as Self-employed Professionals[D]Women and the Jobs MarketText3The old idea that talented children“burn themselves out”in the early years,and,therefore, are subjected to failure and at worst,mental illness is unfounded.As a matter of fact,the outstanding thing that happens to bright kids is that they are very likely to grow into bright adults.To find this out,l,500gifted persons were followed up to their thirty-fifth year with these results:On adult intelligence tests,they scored as high as they had as children.They were,as a group,in good health,physically and mentally.84per cent of their group were married and seemed content with their lives.About70per cent had graduated from college,though only30per cent had graduated with honors.A few had even dropped out,but nearly half of these had returned to graduate.Of the men,80per cent were in one of the professions or in business management or semiprofessional jobs.The women who had remained single had office,business,or professional occupations.The group had published90books and1,500articles in scientific,scholarly,and literary magazines and had collected more than100patents.In a material way they did not do badly either.Average income was considerably higher among the gifted people,especially the men,than for the country as a whole,despite their comparative youth.In fact,far from being strange,most of the gifted were turning their early promise into practical reality.23.The old idea that talented children“burn themselves out”in the early years is________.[A]true in all senses[B]refuted by the author[C]medically proven[D]a belief of the author24.The survey of bright children was made to________.[A]find out what had happened to talented children when they became adults[B]prove that talented children“burn themselves out”in the early years[C]discover the percentage of those mentally ill among the gifted[D]prove that talented children never burn themselves out25.Intelligence tests showed that________.[A]bright children were unlikely to be mentally healthy[B]between childhood and adulthood there was a considerable loss of intelligence[C]talented children were most likely to become gifted adults[D]when talented children grew into adults,they made low scoresSection III Cloze TestFor each numbered blank in the following passage there are four choices labeled[A],[B],[C], and[D].Choose the best one and

Mark your answers on the ANSWER SHEET. (40 points)Text 1Financial regulators in Britain have imposed a rather unusual rule on the bosses of big banks. Starting next year, any guaranteed bonus of top executives could be delayed 10 years if their banks are under investigation for wrongdoing. The main pur pose of this “clawback” rule is to hold bankers accountable for harmful risk-taking and to restore public trust in financial institution. Yet officials also hope for a much larger benefit: more long term decision-making not only by banks but by all corporations, to build a stronger economy for future generations.“Short-termism” or the desire for quick profits, has worsened in publicly traded companies, says the Bank of England’s top economist. Andrew Haldane. He quotes a giant of classical economics, Alfred Marshall, in describing this financial impatience as acting like “Children who pick the plums out of their pudding to eat them at once” rather than putting them aside to be eaten last.The average time for holding a stock in both the United States and Britain, he notes, has dropped from seven years to seven months in recent decades. Transient investors, who demand high quarterly profits from companies, can hinder a firm’s efforts to invest in long-term research or to build up customer loyalty. This h as been dubbed “quarterly capitalism”In addition, new digital technologies have allowed more rapid trading of equities, quicker use of information, and thus shorters attention spans in financial markets. "There seems to be a predominance of short-term thinking at the expense of long-term investing,” said Commissioner Daniel Gallagher of the US Securities and Exchange Commission in a speech this week.In the US, the Sarbanes-Oxley Acl of 2002 has pushed most public companies to defer performance bonuses for senior executives by about a year, slightly helping reduce “short-termism .” In its latest survey of CEO pay ,The Wall Street Journal finds that “a substantial part ” of executive pay is now tied to performance .Much more could be done to encourage “lon g-termism,” such as changes in the taxcode and quicker disclosure of stock acquisitions. In France, shareholders who hold onto a company investment for at least two years can sometimes earn more voting rights in a company.Within companies, the right compensation design can provide incentives for executives to think beyond their own time at the company and on behalf of all stakeholders. Britain's new rule is a reminder to bankers that society has an interest in their performance, not just for the short term but for the long term.21.According to Paragraph 1, one motive in imposing the new rule is theA. enhance bankers’ sense of responsibilityB. help corporations achieve larger profitsC. build a new system of financial regulationD. guarantee the bonuses of top executives22.Alfred Marshall is quoted to indicateA. the conditions for generating quick profitsB. governments’ impatience in decision-makingC. the solid structure of publicly traded companiesD. “short-termism” in economic activities23.It is argued that the influence of transient investment on public companies can beA. indirectB. adverseC. minimalD. temporary24.The US and France examples and used to illustrateA. the obstacles to preventing “short-termism”.B. the significance of long-term thinking.C. the approaches to promoting “long-termism”.D. the prevalence of short-term thinking.25.Which of the following would be the best title for the text?A. Failure of Quarterly CapitalismB. Patience as a Corporate VirtueC. Decisiveness Required of Top ExecutivesD. Frustration of Risk-taking BankersText 2Grade inflation—the gradual increase in average GPAs (grade-point averages) over the pastfew decades—is often considered a product of a consumer era in higher education, in which students are treated like customers to be pleased. But another, related force—a policy often buried deep in course catalogs called "grade forgiveness"— is helping raise GPAs.Grade forgiveness allows students to retake a course in which they received a low grade, and the most recent grade or the highest grade is the only one that counts in calculating a student’s overall GPA.The use of this little-known practice has accelerated in recent years, as colleges continue to do their utmost to keep students in school (and paying tuition) and improve their graduation rates. When this practice first started decades ago, it was usually limited to freshmen, to give them a second chance to take a class in their first year if they struggled in their transition to college-level courses. But now most colleges, save for many selective campuses, allow all undergraduates, and even graduate students, to get their low grades forgiven.College officials tend to emphasize that the goal of grade forgiveness is less about the grade itself and more about encouraging students to retake courses critical to their degree program and graduation without incurring a big penalty. “Untimely,” said Jack Miner, Ohio State University’s registrar, “we see students achieve more success because they retake a course and do better in subsequent contents or master the content that allows them to graduate on time.”That said, there is a way in which grade forgiveness satisfies colleges’ own needs as well. For public institutions, state funds are sometimes tied partly to their success on metrics such as graduation rates and student retention—so better grades can, by boosting figures like those, mean more money. And anything that raises GPAs will likely make students—who, at the end of the day, are paying the bill—feel they’ve gotten a better value for their tuition dollars, which is another big concern for colleges.Indeed, grade forgiveness is just another way that universities are responding to consumers’ expectations for higher education. Since students and parents expect a college degree to lead to a job, it is in the best interest of a school to turn out graduates who are as qualified as possible—or at least appear to be. On this, students’ and colleges' incentives seem to be aligned.26.What is commonly regarded as the cause of grade inflation?A.The change of course catalogs.B.Students' indifference to GPAS.C.Colleges' neglect of GPAS.D.The influence of consumer culture.27.What was the original purpose of grade forgiveness?A.To help freshmen adapt to college learning.B.To maintain colleges' graduation rates.C.To prepare graduates for a challenging future.D.To increase universities' income from tuition.28.According to Paragraph 5, grade forgiveness enables colleges toA.obtain more financial support.B.boost their student enrollments.C.improve their teaching quality.D.meet local governments' needs.29.What does the phrase "to be aligned"(Line 5, Para. 6) most probably mean?A.To counterbalance each other.Text 3This year marks exactly two centuries since the publication of Frankenstein; or, The Modern Prometheus, by Mary Shelley. Even before the invention of the electric light bulb, the author produced a remarkable work of speculative fiction that would foreshadow many ethical questions to be raised by technologies yet to come.Today the rapid growth of artificial intelligence (AI) raises fundamental questions: “What is intelligence, identity, or consciousness? What makes humans humans?”What is being called artificial general intelligence, machines that would imitate the way humans think, continues to evade scientists. Yet humans remain fascinated by the idea of robots that would look, move, and respond like humans, similar to those recently depicted on popular sci-fi TV series such as “West world” and “Humans”.Just how people think is still far too complex to be understood, let alone reproduced, says David Eagleman, a Stanford University neuroscientist. “We are just in a situation where there are no good theories explaining what consciousness actually is and how you could ever build a machine to get there.”But that doesn’t mean crucial ethical issues involving AI aren’t at hand. The coming use of autonomous vehicles, for example, poses thorny ethical questions. Human drivers sometimes must make split-second decisions. Their reactions may be a complex combination of instant reflexes, input from past driving experiences, and what their eyes and ears tell them in that moment. AI “vision” today is not nearly as sophisticated as that of humans. And to anticipate every imaginable driving situation is a difficult programming problem.Whenever decisions are based on masses of data, “you quickly get into a lot of ethical questions,” notes Tan Kiat How, chief executive of a Singapore-based agency that is helping the government develop a voluntary code for the ethical use of AI. Along with Singapore, other governments and mega-corporations are beginning to establish their own guidelines. Britain is setting up a data ethics center. India released its AI ethics strategy this spring.On June 7 Google pledged not to “design or deploy Al” that would cause “overall harm,” or to develop Al-directed weapons or use AI for surveillance that would violate international norms. It also pledged not to deploy AI whose use would violate international laws or human rights.While the statement is vague, it represents one starting point. So does the idea that decisions made by AI systems should be explainable, transparent, and fair.To put it another way: How can we make sure that the thinking of intelligent machines reflects humanity’s highest values? Only then will they be useful servants and not Frankenstein’s out-of-control monster.31.Mary Shelley's novel Frankenstein is mentioned because itA. fascinates Al scientists all over the world.B. has remained popular for as long as 200 years.C. involves some concerns raised by Al today.D. has sparked serious ethical controversies32.In David Eagleman's opinion, our current knowledge of consciousnessA. helps explain artificial intelligence.B. can be misleading to robot making.C. inspires popular sci-fi TV series.D.is too limited for us to reproduce it33.The solution to the ethical issues brought by autonomous vehiclesA. can hardly ever be found.B.is still beyond our capacity.C. causes little public concern.D. has aroused much curiosity.34.The author's attitude toward Google's pledges is one ofA. affirmationB. skepticism.C. contemptD. respect.35.Which of the following would be the best title for the text?A. Al's Future: In the Hands of Tech GiantsB. Frankenstein, the Novel Predicting the Age of AlC. The Conscience of AI: Complex But InevitableD. AI Shall Be Killers Once Out of ControlText 4States will be able to force more people to pay sales tax when they make online purchases under a Supreme Court decision Thursday that will leave shoppers with lighter wallets but is a big financial win for states.The Supreme Court's opinion Thursday overruled a pair of decades-old decisions that states said cost them billions of dollars in lost revenue annually. The decisions made it more difficult for states to collect sales tax on certain online purchases.The cases the court overturned said that if a business was shipping a customer's purchase to a state where the business didn't have a physical presence such as a warehouse or office, the business didn't have to collect sales tax for the state. Customers were generally responsible for paying the sales tax to the state themselves if they weren't charged it, but most didn't realize they owed it and few paid.Justice Anthony Kennedy wrote that the previous decisions were flawed. “Each year the physical presence rule becomes further removed from economic reality and results in significant revenue losses to the States,” he wrote in an opinion joined by four oth er justices. Kennedy wrotethat the rule “limited states' ability to seek long-term prosperity and has prevented market participants from competing on an even playing field.”The ruling is a victory for big chains with a presence in many states, since they usually collect sales tax on online purchases already. Now, rivals will be charging sales tax where they hadn't before. Big chains have been collecting sales tax nationwide because they typically have physical stores in whatever state a purchase is being shipped to. , with its network of warehouses, also collects sales tax in every state that charges it, though third-party sellers who use the site don't have to.Until now, many sellers that have a physical presence in only a single state or a few states have been able to avoid charging sales taxes when they ship to addresses outside those states. Sellers that use eBay and Etsy, which provide platforms for smaller sellers, also haven't been collecting sales tax nationwide. Under the ruling Thursday, states can pass lawsrequiring out-of-state sellers to collect the state's sales tax from customers and send it to the state.Retail trade groups praised the ruling, saying it levels the playing field for local and online businesses. The losers, said retail analyst Neil Saunders, are online-only retailers, especially smaller ones. Those retailers may face headaches complying with various state sales tax laws. The Small Business & Entrepreneurship Council advocacy group said in a statement, "Small businesses and internet entrepreneurs are not well served at all by this decision."31. The Supreme Court decision Thursday will A . Dette business’ revolutions with statesB. put most online business in a dilemmaC. make more online shoppers pay sales taxD. force some states to cut sales tax32. It can be learned from paragraphs 2 and 3 that the overruled decision A . have led to the dominance of e-commerceB . have cost consumers a lot over the yearsC. were widely criticized by online purchasesD. were consider unfavorable by states33. According to Justice Anthony Kennedy , the physical presence rule hasA. hindered economic development .B. brought prosperity to the countryC. harmed fair market competitionD. boosted growth in states’ revenue34. Who are most likely to welcome the Supreme Court rulingA. Internet enterpreneursB. Big-chain ownersC. Third-party sellersD. Small retailers35.

These tools can help you win every argument-not in the unhelpful sense of beating your opponents but in the better sense of learning about the issues that divide people. learning why they disagree with us and learning to talk and work together with them. If we readjust our view of arguments –from a verbal fight or tennis game to a reasoned exchange through which we all gainmutual respect, and understanding---then we change the very nature of what it means to “win” an argument.B. Of course, many discussions are not so successful. Still, we need to be careful not to accuse opponents of bad arguments too quickly. We need to learn how to evaluate them properly. A large part of evaluation is calling out bad arguments, but we also need to admit good arguments by opponents and to apply the same critical standards to ourselves. Humility requires you to recognize weakness in your own arguments and sometimes also to accept reasons on the opposite side.C. None of these will be easy but you can start even if others refuse to. Next time you state your position, formulate an argument for what you claim and honestly ask yourself whether your argument is any good. Next time you talk with someone who takes a stand, ask them to give you a reason for their view. Spell out their argument fully and charitably. Assess its strength impartially. Raise objections and listen carefully to their replies.D. Carnegie would be right if arguments were fights, which is how we often think of them. Like physical fights, verbal fights can leave both sides bloodied. Even when you win, you end up no better off. Your prospects would be almost as dismal if arguments were even just competitions-like, say, tennis games. Pairs of opponents hit the ball back and forth until one winner emerges from all who entered. Everybody else loses. This kind of thinking is why so many people try to avoid arguments, especially about politics and religion.E. In his 1936 work How to Win Friends and Influence People, Dale Carnegie wrote: "There is only one way...to get the best of an argument-and that is to avoid it. "This aversion to arguments is common, but it depends on a mistaken view of arguments that causes profound problems for our personal and social lives- and in many ways misses the point of arguing in the first place.F. These views of arguments also undermine reason. If you see a conversation as a fight or competition, you can win by cheating as long as you don't get caught. You will be happyto convince people with bad arguments. You can call their views stupid, or joke about how ignorant they are. None of these tricks will help you understand them, their positions or the issues that divide you, but they can help you win-in one way.G. There is a better way to win arguments. Imagine that you favor increasing the minimum wage in our state, and I do not. If you yell, “Yes,”and I yell. “No,” neither of us learns anything. We neither understand nor respect each other, and we have no basis for compromise or cooperation. In contrast, suppose you give a reasonable argument: that full-time workers should not have to live in poverty. Then I counter with another reasonable argument: that a higher minimum wage will force businesses to employ fewer people for less time. Now we can understand each other's positions and recognize our shared values, since we both care about needy workers.41→42→F→43→44→C→45Part C TranslationDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on the ANSWER SHEET. (10 points) It was only after I started to write a weekly column about the medical journals, and began to read scientific papers from beginning to end, that I realised just how bad much of the medical literature frequently was. I came to recognise various signs of a bad paper: the kind of paper that purports to show that people who eat more than one kilo of broccoli a week were 1.17 times more likely than those who eat less to suffer late in life from pernicious anaemia. (46) There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generates both health scares and short-lived dietary enthusiasms.Why is so much ba d science published? A recent paper, titled “The Natural Selection of Bad Science”, published on the Royal Society’s open science website, attempts to answer this intriguing and important question. It says that the problem is not merely that people do bad science, but that our current system of career advancement positively encourages it. What is important is not truth, but publication, which has become almost an end in itself. There has been a kind of inflationary process at work: (47) nowadays anyone applying for a research post has to have published twice the number of papers that would have beenrequired for the same post only 10 years ago. Never mind the quality, then, count the number.(48) Attempts have been made to curb this tendency, for example, by trying to incorporate some measure of quality as well as quantity into the assessment of an applicant’s papers. This is the famed citation index, that is to say the number of times a paper has been quoted elsewhere in the scientific literature, the assumption being that an important paper will be cited more often than one of small account. (49) This would be reasonable if it were not for the fact that scientists can easily arrange to cite themselves in their future publications, or get associates to do so for them in return for similar favours.Boiling down an individual's output to simple metrics, such as number of publications or journal impacts, entails considerable savings in time, energy and ambiguity. Unfortunately, the long-term costs of using simple quantitative metrics to assess researcher merit are likely to be quite great. (50)If we are serious about ensuring that our science is both meaningful and reproducible. We must ensure that our institutions encourage that kind of science.46.

Cloze Test ( 10 minutes, 10 points, 1 point each)The chicken is probably the most populous bird on earth. According to 41 , there are over 13 billion chicken ! And its meat is to popular that more than 73 billion pounds of it are consumed each year. 42 , hens produce some 600 billion eggs a year worldwide.The chicken is a descendant of the red jungle fowl of Asia. Man soon discovered that the chicken could be domesticated easily. But it was 43 the 19th century that mass production of chickens and eggs became a commercial 44 .Today chicken is 45 the most popular poultry meat. Chickens are raised by millions of households for domestic and commercial use.Advanced scientific methods of breeding and raising have made chicken production one of the most successful agricultural industries. Modern techniques now make 46 possible for just one person to care for from 25, 000 to 50,000 chickens. It takes the birds only three months to reach market weight. Many people 47 these mass-production techniques as cruel. But that has not stopped farmers from developing increasingly efficient ways of breeding these birds. Many of the birds raised by such methods are easily to die off---- some as 48 of the deadly disease ----the bird flu. Many farmers have neither the 49 nor the means to feed their chickens adequately, to provide proper housing for them, or to protect them from diseases. 50 this reason programs have been started by the United Nations to help educate farmers in many countries.41.

Functional and often unexciting, replaced by zip fasteners or hood and eyes, there is, one would think, nothing much to be said about the humble button.Yet it is very probable that buttons started life as ornaments; certainly it is not known that they had any practical function until the 13th century. By the 14th century buttons were once again ornamental, often wastefully so, to such an extent that it was by no means uncommon for a person of wealth and consequence to have as many as 300 buttons on a single article of dress. Unimaginable as it seems today, sewing superfluous buttons on cloths became a craze---- not one that seems harmful to us though some Italians took a different view and a law against buttons was enforced in Florence. No buttons were to be worn on the upper arms; penalty for disobedience---- a sound whipping. How often this had to be carried out, history does not relate!Most of the buttons on modern clothes which could be called decorative once did in fact serve a useful purpose. Buttons on boots are one good example. Sleeve buttons on men’s coats are a reminder of the days when the fashion was for wearing shirts with frilly lace cuffs.On the tails of a modern tail coat there are indeed buttons which are purely ornamental but in earlier dayshorsemen used these buttons to keep the tails out of harm’s way.With regard to the side on which clothes are buttoned, originally both male and female dress was buttoned on the left hand side. Change came when men had to have access to their swords.So perhaps it is worth taking a look at buttons.51. Which of the following statements is true regarding buttons?A They have little function.B They are the only useful accessory.C They receive the least attention among accessories.D They are one of the best adornments to any clothes.52. According to the author, ____A buttons are used as ornaments only in modern times.B buttons have been used as ornaments since the 14th century.C buttons were used as ornaments before the 13th century.D buttons have been used as ornaments on and off throughout the history.53. It is implied that in the 14th century buttons ________A were a symbol of wealth.B were occasionally put on clothes.C began to have practical functions.D represented the wearer’s artistic taste54. In Florence, a city in Italy, buttons were once ___A loved by every citizen .B banned because they were a craze.C considered harmful and nobody wore them.D forbidden on the upper arms.55. It seems to the author that buttons ____A are worth a second look.B have never served any functionC should not be sewed on coats.D play an important role in our lives.56. Male and female dress is now buttoned __________A on the right sideB on the left sideC on different sides C on the same sides.Passage TwoBehind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On the one hand, we assume that we are indestructible. On the other, we think that any damage we impose on ourselves can be undone when finally clean up our act.If the evidence for how wrong the first idea is isn’t apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?To a surprising degree, the answer is yes. Over the past five years, scientists have accumulated a wealth of data about what happens when aging people with bad habits decide to turn their lives around. The heartening conclusion: the body has an amazing ability to heal itself,provided the damage is not too great.The effects of some bad habits ---smoking, in particular---can haunt you for decades. But the damage from other habits can be largely healed.“Any time you improve your behaviour and make lifestyle changes, they make a difference from that point on,” says Dr. Jeffrey Koplan. “Maybe not right away. It’s like slamming on the brakes. You do need a certain distance. “But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research:---- A study concluded that women who consume a s little as two servings of fish a week cut their risk of suffering a stroke to half that women who eat less than one serving of fish a month.---- The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline.Adopting healthy habits won’t cure all that bothers you, of course. But doctors believe that many chronic diseases ----from high blood pressure to heart disease and even some cancers---- can be warded off with a few sensible changes in lifestyle.N ot sure where to start? Surprisingly, it doesn’t matter, since one positive change usually leads to another. Make en ough changes, and you’ll discover you’ve adopted a new way of life.57. Most people with bad habits of eating more than they should believe that ____A they can never change the habits that have haunted them for decades.B their bodies can’t be damaged by the bad habits.C their bodies can heal all the damage without the help from outside.D they can force themselves to clean up the bad habits later.58. The evidence to disapprove the assumption that we are indestructible ____A is seldom apparent .B is clearly shown in the mirror.C will appear obvious sooner or later.D is still a question.59. According to the passage the human body can heal the damage caused by bad habits _______A when the damage is not very serious.B no matter how serious the damage is.C after we have dropped our bad habits.D much more slowly than we think.60. According to the recent announcements, ____A women should eat as much fish as possible.B women are at a higher risk of suffering a stroke than men.C eating a little more f ish can improve women’s health.D men don’t have to eat as much fish as women.61. It is implied in the passage that _____A smokers have lower levels of carbon monoxide than non-smokers.B the blood of smokers is more sticky than that of non-smokers.C smokers will be unlikely to die from heart attack if they quit smoking.D chronic diseases can be cured if we drop our habit of smoking.62. In the last paragraph the author tells us _____A when we should start quitting our bad habits.B it doesn’t matter how we start quitting our bad habits.C that making enough changes will make doctors unnecessary to us.D it’s never too late to start making sensible changes in our lifestyle.Passage ThreeOur true challenge today is not debts and deficits or global competition but the need to find a way to live rich, fulfilling lives without destroying the planet’s biosphere, which supports all life. Humanity has never before faced such a threat: the collapse of the very elements that keep us alive.An apple is an easy thing to take for granted. If you live where apples grow in abundance, you might assume that they are readily available and, better yet, that you may pick from a wide variety. But do you know that there are far fewer types to choose from today than there were 100 years ago?Between the years 1804 and 1905, there were 7,098 varieties of apples grown in the United States. Today 6,121 of those are extinct. But does diversity really matter?In the 1840’s, Ireland’s population exceeded eight million, making it the most densely populated country in Europe. Potatoes were its dietary mainstay, and a single variety called lumpers was the most widely grown.In 1845 the farmers planted their lumpers as usual, but a plant disease known as blight struck and wiped out almost the entire crop. “Most of Ireland survived that difficult year,” wrote Paul Raeburn in his book The Last Harvest ----The Genetic Gamble That Threatens to Destroy American Agriculture. “The devas tation came the next year. Farmers has no choice but to plant the same potatoes again. They had no other varieties. The blight struck again, this time with overwhelming force. The suffering was indescribable.” Historians estimate that up to 1 million people died of starvation, while another 1.5 million emigrated, most to the United States. Those remaining suffered from crushing poverty.In the Andes of South America, farmers grew many varieties of potatoes, and only a few were affected by blight. Hence, there was no epidemic. Clearly, diversity of species and diversity within species provide protection. The growing of just one uniform crop runs counter to this basic survival strategy and leaves plants exposed to diseaseor pests, which can destroy an enti re regions’ harvest. That is why many farmers depend so heavily on the frequent use of pesticides , even though such chemicals are often environmentally hazardous.Why do farmers replace their many folk varieties with one uniform crop? Usually in response to economic pressures. Planting uniform crops promises ease of harvesting, attractiveness of the product, resistance to go bad, and high productivity. But theses trends may be destroying man’s own food supply.63. The main idea of the passage is __________A It is important to protect the earth’s bio-diversity.B man is destroying his own food supply.C we now have fewer bio-species than before.D numerous strains of plants can resist plagues.64. With regard to the variety of apples in the United States ___________A it is the fewest in variety in terms of plant family.B over 80% of its varieties have been destroyed.C we have done our best to protect it.D it is as wide as it was 100 years ago.65. The author tells the sto ry in Ireland in the 1840’s to show that _________A farmers should grow as many varieties of potatoes as in South America.B potatoes should not be grown as a dietary mainstay.C lumpers were not a choice variety of potatoes.D bio-diversity is essential to life on earth.66. The uniform crop of lumpers in Ireland in the 1840’s__________A caused blight to strike Ireland repeatedly.B caused Ireland’s population to decline by half.C destroyed the whole Irish agricultural tradition.D se riously devastated Ireland’s economy.67. Diversity of species and diversity within species can help plants_________A ward off some disastrous diseases and pests.B resist natural disasters such as droughts.C withstand the harmful effect of pesticides.D yield bumper harvests.68. Which of the following is NOT the reason that farmers replace their folk varieties with one uniform crop?A They want to make more money.B They want to have a higher output.C They want to prevent the destruction of human food.D They want to make their products more attractive. Passage FourIt is a well-documented fact that women still live longer than men. A 1998 study by Harvard Medical School geriatrician Thomas Perls offers two reasons: one is the evolutionary drive to pass on her genes; the other is the need to stay healthy enough to rear as many children as possible. A man’s purpose is simply to carry genes that ensure longevity and pass them on to his children.Okay, so that’s the legacy of our cave-dweller past. But what is it about a man’s lifestyle that reduces his longevity? As action moviemakers know all too well , men are supercharged with testosterone. Aside from forcing us to watch frenzied movies like The Matrix Reloaded, the testes-produced hormone also triggers riskier behavior and aggression, and increases levels of harmful cholesterol, raising the risk of heart disease of stroke. Meanwhile, the female hormone chops harmful cholesterol and raises “good” cholesterol.As Perls’s study points out: “Between ages 15 and 24, men are four to five times more likely to die than women. This time frame coincides with the onset of puberty and an increase in reckless and violent behavior in males. Researchers refer to it as a ‘testosterone storm.’ Most deaths in this male group come from motor vehicle accidents, followed by homicide, suicide….and drownings.”While all this jumping from tall buildings may result in some accidental death, it still doesn’t account for the onset of fatal illnesses at an earlier age. Statistically, men are crippled more quickly by illnesses like heart disease, stroke and cancer. A Singapore study found that while men were diagnosed with chronic illness two years earlier than women, women were also disabled by their illnesses four years later. Men more often engage in riskier habits like drinking alcohol and using recreational drugs, as well as eating to excess. And the stereotype about men being adverse to seeing a doctor on a regular basis? Studies have shown its’ t rue.If your goal is to become the first 100-year-old man on your family tree, there are some things you can do to boost your odds. One is to examine what centenarians are doing right. According to the ongoing New EnglandCentenarian Study, the largest comprehensive study of centenarians in the world, they can fend off or even escape age-associated diseases like heart attack, stroke, canc er, diabetes and Alzheimer’s. Ninety percent of those studied were functionally independent for the vast majority of their lives up until the age of 92 , and 75% were just as autonomous at an average age of 95. “Centenarians disprove the perception that ‘the older you get, the sicker you get.’ Centenarians teach us that the older you get, the healthier you’ve been.”69. This passage mainly discusses ________A why women lead a healthier life than men.B how women can live longer and stay healthy.C what keeps men from enjoying a longer life span.D whether men’s life style lead s to their early death.70. According to Thomas Perls, which of the following is a major factor contributing to the relative longevity of women over men?A Their natural urge to remain healthy.B Their greater natural drive to pass on genes.C Their need to bear healthy offspring.D Their desire to have more children.71. The author mentions “the legacy of our cave-dweller past” to __________A support the argument about women’s role in rearing children.B summarize a possible cause of different life expectancies.C challenge the the ory about our ancestor’s behaviour patterns.D illustrate the history of human evolution process.72. According to the passage, testosterone is a hormone that _______A increases as men grow older.B reduces risk factors in male behaviour.C leads to aggressive behaviour and heart disease.D accounts for women’s dislike for violent films.73. Compared with women, men as a whole ____.A suffer from depression more often.B suffer from diseases later than women.C are reluctant to have physical checkups.D are not affected by violent movies.74. Centenarians refer to people who ____A live longer than females.B live at the turn of the century.C are extremely independent.D are a hundred years or older.Passage FiveLast year, Curt Dunnam bought a Chevrolet Blazer with one of the most popular new features in high-end cars: the Onstar personal security system.The heavily advertised communications and tracking feature is used nationwide by more than two million drivers, who simply push a button to connect, via a built-in cell-phone, to a member of the Onstar staff. A Global Positioning System, or G.P.S., helps the employee give verbal directions to the driver or locate the car after an accident. The company can even send a signal to unlock car doors for locked-out owners, or honk the horn to help people find their cars in an endless plain of parking spaces. The biggest selling point for the system is its use in frustrating car thieves. Once an owner reports to the police that a car has been stolen, the company can track it to help arrest the thieves, a service it performs about 400 times each month.But for Mr. Dunnam, the more he learned about his car’s security features, the less secure he felt. He has enough technical knowledge to worry that someone else---- law enforcement officers, or hackers----could listen in one his phone calls, or gain control over his automotive systems without his knowledge or consent. “While I don’t believe G.M. intentionally designed this syste m to facilitate such activities, they sure have made it easy,” he said. Mr. Dunnam said he had become even more concerned because of a federal appeals court case involving a criminal investigation, in which federal authorities had demanded that a company attach a wiretap to tracking services like those installed in his car. The suit did not reveal which company was involved. A three-judge panel in San Francisco rejected the request, but not on privacy grounds; the panel said the wiretap would interfere with the operation of the safety services. Onstar has said that its equipment was not involved in that case. An Onstar spokeswoman, Geri Lama, suggested that Mr. Dunnam’s worries were overblown. The signals that the companysends to unlock car doors or track location-based information can be triggered only with a secure exchange of specific identifying data, which ought to hinder all but the most determined hackers, she said.75. The most important feature of Onstar advertised by the company is that it can ____A help people find their cars in the big parking lot.B giver verbal direction to drivers lost in unfamiliar areas.C open car doors for owners unable to find their car keys.D make it difficult for thieves to get away with stolen cars.76. We can conclude from the passage that Onstar is ______A too complicated to use especially for new drivers.B not as usual and effective as the company claims.C popularly used among the more expensive cars.D not widely used in the country except in a few states.77. Mr. Dunnam felt dissatisfied with OnStar because _______A his personal information might be revealed.B his demand for better services was rejected.C OnStar posed potential danger to driving safety.D OnStar had been developed mainly to facilitate police work.78. The three-judge panel rejected the request of the federal authorities because _____A it was in violation of individual privacy.B it was against the Constitution of the nation.C the wiretap might affect the safety of personal data.D the wiretap might reduce the efficiency of the system.79. OnStar spokeswoman suggested that Mr. Dunnam’s worries ___________A exaggerated the problems that might occur.B represented reasonable concerns of customers.C presented problems for them to solve.D made sense due to the existence of hackers.80. The passage is mainly written to _______A promote the brand and sale of OnStar.B pint out the worries caused by OnStar.C introduce the new features of OnStar.D show the future trend represented by OnStar .Paper TwoPart V Translation (30 minutes, 20 points )Section A (15minutes, 10 points )As a branch of cognitive science, linguistics has undergone systematic inquiry and elaboration in terms of language acquisition and classification.When it comes to language learning, the spelling of Chinese characters is notoriously difficult to Westerners, who are often left puzzled about numerous strokes. In China, the myth remains that maximum efficiency can be achieved by exposing young children to native speakers as early as possible. However, a more profound insight into the process of language acquisition wo n’t be gained until studies of the brain have developed to the point where the function of each part of the brain is brought to light. The eagerness to make children proficient in English on the part of parents in China is open to question.Section B (15 minutes, 10 points)计算机被认为是有史以来对人类生活影响最大的发明。

C or D.Mark your answers on the ANSWER SHEET (40 points)Text 1Financial regulators in Britain have imposed a rather unusual rule on the bosses of big banks.Starting next year. any guaranteed bonus of top executives could be delayed 1o years if their banks are under investigation for wrongdoing. The main purpose of this " clawback" rule is to hold bankers accountable for harmful risk taking and to restore public trust in financial institution, Yet officials also hope for a much larger benefit: more long term decision-making not only by banks but by all corporations, to build a stronger economy for future generations.“Short-termism”or the desire for quick profits, has worsened in publicly traded companies.says the Bank of England's top economist. Andrew Haldane. He quotes a gaint of classicaleconomics, Alfred Marshall in describing this financial impatience as acting like" Children whopick the plums out of their pudding to eat them at once”rather than putting them aside to be eaten last.The average time for holding a stock in both the United States and Britain. he notes hasdropped from seven years to seven months in recent decades. Transient investors, who demandhigh quarterly profits from companies, can hinder a firms efforts to invest inlone-term researchor to build up customer loyalty. This has been dubbed "quarterly capitalism”.In addition, new digital technologies have allowed more rapid trading of equities quicker useof information, and thus shorters attention spans in financial markets. " There seems to be apredominance of short- term thinking at the expense of long-term investing,”said CommissionerDaniel Gallagher of the US Securities and Exchange Commission in a speech this week.In the US, the Sarbanes-Oxley Acl of 2002 has pushed most public companies to deferperformance bonuses for senior executives by about a year, slightly helping reduce"short-termism. " In its latest survey of CEO pay The Wall street Journal finds that"a substantial part"of executive pay is now tied to performance.Much more could be done to encourage "long-termism, such as changes in the tax codeand quicker disclosure of stock acquisitions. In France, shareholders who hold onto a companyinvestment for at least two years can sometimes can more voting rights in a company.Within companies, the right compensation design can provide incentives for executives tothink beyond their own time at the company and on behalf of all stakeholders, Britain’s new rule is a reminder to bankers that society has an interest in their performance not just for the short term but for the long term.21. According to Paragraph 1, one motive in imposing the new rule is theA. enhance bankers' sense of responsibilityB help corporations achieve larger profitsC. build a new system of financial regulationD. guarantee the bonuses of top executives22. Alfred Marshall is quoted to indicateA. the conditions for generating quick profitsB. governments impatience in decision-makingC. the solid structure of publicly traded companiesD. "short-termism" in economic activities23. It is argued that the influence of transient investment on public companies can beA. inditedB. adverseC. minimal D temporary24. The US and France examples and used to illustrateA. the obstacles to preventing "short-termism.B. the significance or long term thinking.C. the approaches to promoting long-termism.D. the prevalence of short-term thinking.25. Which of the following would be the best title for the textA. Failure of Quarterly CapitalismB. Patience as a Corporate VirtueC. Decisiveness Required of Top ExecutivesD. Frustration of Risk-taking BankersText 2Grade inflation-the gradual increase in average GPAs (grade-point averages) over the pastfew decades-is often considered a product of a consumer era in higher education, in whichstudents are treated like customers to be pleased. But another, related force -a policy often buried deep in course catalogs called grade forgiveness"- is helping raise GPAs.Grade forgiveness allows students to retake a course in which they received a low grade, andthe most recent grade or the highest grade is the only one that counts in calculating a student'soverall GPA.The use of this little-known practice has accelerated in recent years, as colleges continue todo their utmost to keep students in school (and paying tuition) and improve their gradation rates.When this practice fir started decades ago, it was usually limited to freshmen, to give them asecond chance to take a class in their first year if they struggled in their transition to college-levelcourses. But now most colleges, save for many selective campuses, allow all undergraduates, andeven graduate students, to get their low grades forgiven.College officials tend to emphasize that the goal of grade forgiveness is less about the gradeitself and more about encouraging students to retake courses critical to their degree program andgradation without incurring a big penalty. "Untimely. "said Jack Mine, Ohio State University'sregistrar. "we see students achieve more success because they retake a course and do better insubsequent contents or master the content that allows them to graduate on time. That said, there is a way in which grade forgiveness satisfies colleges own needs as well. Forpublic institutions state finds are sometimes tied partly to their success on metrics such asgraduation rates and student retention so better grades can, by boosting figures like those, meanmore money. And anything that raises GPAs will likely make students who, at the end of the dayare paying the bill-feel they’ve gotten a better value for their tuition dollars, which is another bigconcern for colleges.Indeed grade forgiveness is just another way that universities are responding to consumers'expectations for higher education. Since students and parents expect a college degree to lead to a job, it is in the best interest of a school to tum out gradates who are as qualified as possible-orat least appear to be. On this, students' and colleges’incentives seem to be aligned.26. What is commonly regarded as the cause of grade inflation?A. The change of course catalogs.B. Students indifference to GPAS.C Colleges neglect of GPAS.D. The influence of consumer culture.27. What was the original purpose of grade forgivenessA. To help freshmen adapt to college learning.B. To maintain colleges graduation rates.C. To prepare graduates for a challenging future.D. To increase universities’income from tuition.28. According to Paragraph 5. grade forgiveness enables collegesA. obtain more financial support.B. boost their student enrollments.C. improve their teaching quality.D. meet local governments’needs.29. What does the phrase “to be aligned”(Line 5. Para. 6) most probably mean?A. To counterbalance each otherB. To complement each other.C. To be identical with each otherD. To be contradictory to each other.30. The author examines the practice of grade forgiveness byA assessing its feasibilityB.analyzing the causes behind it.C. comparing different views on it.D. listing its long-run effectsText 3This year marks exactly two centuries since the publication of Frankenstein, or. The ModemPrometheus by Mary Shelley. Even before the invention of the electric light bulb, the authorproduced a remarkable work of speculative fiction that would foreshadow many chical questionsto be raised by technologies yet to come.Today the rapid growth of artificial intelligence (An) raises fundamental questions: "What isintelligence, identity, or consciousness? what makes humans humans?What is being called artificial general intelligence, machines that would imitate the wayhumans think continues to evade scientists. Yet humans remain fascinated by the idea of robotsthat would look, move, and respond like humans, similar to those recently depicted on popularsci-fi Tv series such as"Westworld and"Humans".Just how people think is still far too complex to be understood let alone reproduced, saysDavid Eagleman, a Stanford University neuroscientist, "We are just in a situation where there areno good theories explaining what consciousness actually is and how you could ever build a machine to get there.”But that doesn't mean crucial ethical issues involving Al aren't at hand. The coming use ofautonomous vehicles. for example poses thorny ethical questions. Human drivers sometimemake split-second decisions. Their reactions may be a complex combination of instant reflexes.input from past driving experiences, and what their eyes and ears tell them in that moment. AI"vision"today is not nearly as sophisticated as that of humans. And to anticipate every imaginable driving situation is a difficult programming problem. Whenever decisions are based on masses of data. "you quickly get into a lot of ethicalquestions, "notes Tan Kiat How, chief executive of a Singapore-based agency that is helping thegovernment develop a voluntary code for the ethical use of Al. Along with Singapore, othergovernments and mega-corporations are beginning to establish their own guidelines. Britain issetting up a data ethics center. India released its Al ethics strategy this spring.On June 7 Google pledged not to"design or deploy Ar" that would cause"overall harm, "orto develop Al-directed weapons or use Al for surveillance that would violate international norms.It also pledged not to deploy AI whose use would violate international laws or human rights.While the statement is vague, it represents one starting point, So does the idea that decisions made by Al systems should be explainable, transparent. and fair.To put it another way. How can we make sure that the thinking of intelligent machines reflects humanity’s highest values? Only then will they be useful servants and not Frankenstein’s out-of-control monster.31. Mary Shelley’s novel Frankenstein is mentioned becauseA. fascinates Al scientists all over the worldB.has remained popular for as long as 200 years.C. involves some concerns raised by Al todayD.has sparked serious ethical controversies32. In David Eagleman's opinion, our current knowledge of consciousnessA. helps explain artificial intelligence.B. can be misleading to robot makingC. inspires popular sci-fi TV seriesD.is too limited for us to reproduce it33.The solution to the ethical issues brought by autonomous vehiclesA. can hardly ever be found.B. is still beyond our capacityC. causes little public concernD.has aroused much curiosity34. The authors attitude toward Google’s pledges is one ofA. AffirmationB. skepticismC. contemptD. respect35. Which of the following would be the best title for the text?A. Al’s Future: In the Hands of Tech giantsB. Frankenstein, the Novel Predicting the Age of AC. The Conscience of Al: Complex But InevitableD. AI Shall Be Killers once out of ControlText 4States will be able to force more people to pay sales tax when they make online purchasesunder a Supreme Court decision Thursday that will leave shoppers with lighter wallets but is a bigfinancial win for states.The Supreme Courts opinion Thursday overruled a pair of decades-old decisions that statessaid cost them billions of dollars in lost revenue annually. The decisions made it more difficult forstates to collect sales tax on certain online purchases.The cases the court overturned said that if a business was shipping a customers purchase to a state where the business didn’t have a physical presence such as a warehouse or office. thebusiness did 't have to collect sales tax for the state. Customers were generally responsible forpaying the sales tax to the state themselves if they weren’t charged it, but most didn’t realize they owed it and few paid.Justice Anthony Kennedy wrote that the previous decisions were flawed. Each year thephysical presence rule becomes further removed from economic reality and results in significantrevenue losses to the States." he wrote in an opinion joined by four other justices, Kennedy wrote that the rule limited states ability to seek long-term prosperity and has prevented marketparticipants from competing on an even playing field.”The ruling is a victory for big chains with a presence in many states, since they usuallycollect sales tax on online purchases already Now, rivals will be charging sales tax where theyhadn't before, Big chains have been collecting sales tax nationwide because they typically havephysical stores in whatever state a purchase is being shipped to. Amazon. com. with its network of warehouses also collects sales tax in every state that charges it, though third-party sellers who use the site don 't have to.Until now, many sellers that have a physical presence in only a single state or a few stateshave been able to avoid charging sales taxes when they ship to addresses outside those statesSellers that use eBay and Etsy. which provide platforms for smaller sellers, also hat collecting sales tax nationwide. Under the ruling Thursday, states can pass laws out.. state sellers to collect the state's sales tax from customers and send it to the staleRetail trade groups praised the ruling. saying it levels the playing field for local and onlinebusinesses. The losers, said retail analyst Neil Saunders, are online-only retailers especiallysmaller ones. Those retailers may face headaches complying with various state sales tax laws. TheSmall Business Entrepreneurship Council advocacy group said in a statement "Smallbusinesses and internet entrepreneurs are not well served at all by this decision.36. The Supreme Court decision Thursday willA. Dette business relations with statesB. put most online business in a dilemmaC. make more online shoppers pay sules taxD. force some sates to ct sales tax37. It can be learned from paragraph 2 and 3 that the overruled decisionsA. have led to the domainance of e-commerceB. have cost consumers a lot over the yearsC. were widely criticized by online purchaseD. were consider unfavorable by states38. According to Justice Anthony Kennedy, the physical presence rule hasA. hindered economic developmentB. brought prosperity to the countryC. harmed fair market competitionD. Boosted growth in states, revenue39. Who are most likely to welcome the Supreme Court rulingA. Internet entrepreneursB. Big- chair ownersB. Third-party sellersD. Small retailers40. In dealing with the Supreme Court decision Thursday the authorA. gives a factual account of it and discusses its consequencesB. describes the long and complicated process of its makingC. presents its main points with conflicting views on themD. cities some saces related to it and analyzes their implications Part BDirections.The following paragraphs are given in a wrong order. For Questions 41-45. you are required to reorganize these paragraphs into a coherent article by choosing from the list A-G and filling then into the numbered boxes. Paragraphs C and F have been correctly placed. Mark your answers on ANSWER SHEET. (10 points)A. These tools can help you win every argument- not in the unhelpful sense of beating youropponents but in the better sense of learning about the issues that divide people learning why they disagree with us and learning to talk and work together with them. If we readjust our view of arguments-from a verbal fight or tennis game to a reasoned exchange through which we all gain mutual respect, and understanding-then we change the very nature of what it means to"win"an argument.B. Of course, many discussions are not so successful. Still, we need to be careful not to accuseopponents of bad arguments too quickly. We need to lean how to evaluate them properly. A largepart of evaluation is calling out bad arguments, but we also need to admit good arguments byopponents and to apply the same critical standards to ourselves. Humility requires you to recognize weakness in your own arguments and sometimes also to accept reasons on the opposite side.C. None of these will be easy but you can start even if others refuse to Next time you state yourposition, formulate an argument for what you claim and honestly ask yourself whether yourargument is any good. Next time you talk with someone who takes a stand, ask them to give you a reason for their view Spell out their argument fully and charitably. Assess its strength impartially. Raise objections and listen carefully to their replies.D. Carnegie would be right if arguments were fights, which is how we often think of them. Likephysical tights, verbal fights can leave both sides bloodied. Even when you win, you end up nobetter off. Your prospects would be almost as dismal if arguments were even just competitions like. Say, tennis games. Pairs of opponents hit the ball back and forth until one winner emerges from all who entered. Everybody else loses. This kind ofthinking is why so many people try to avoid arguments. especially about politics and religion.E. In his 1936 work How to Win Friends and Influence People, Dale Carnegie wrote: "There isonly one way. to get the best of an argument-and that is to avoid it. " This aversion to arguments is common, but it depends on a mistaken view of arguments that causes profound problems for our personal and social lives- and in many ways misses the point of arguing in the first place.F. These views of arguments also undermine reason. If you see a conversation as a fight orcompetition. you can win by cheating as long as you don go caught. You will be happy toconvince people with bad arguments. You can call their views stupid or joke about how ignorantthey are. None of these tricks will help you understand them, their positions or the issues thatdivide you, but they can help you win-in one way.G. There is a better way to win arguments. Imagine that you favor increasing the minimum wagein our state, and I do not. If you yell, "Yes, "and I yell. "No, "neither of us learns anything. Weneither understand nor respect each other. and we have no basis for compromise or cooperation. In contrast, suppose you give a reasonable argument: that full-time workers should not have to live in poverty. Then I counter with another reasonable argument: that a higher minimum wage will force businesses to employ fewer people for less time. Now we can understand each other's positions and recognize our shared values, since we both care about needy workers.41-42-F-43-44-C-45Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on the ANSWER SHEET. (10 points)It was only after I started to write a weekly column about the medical journals, and begread scientific papers from beginning to end that I realized just how bad much of the medical literature frequency was, I came to recognize various sins of a bad paper: the kind of paper that purports to show that people who est more than one kilo of broccoli a week were 1.17 times more likely than those who eat less to suffer late in life from pernicious anaemia. 46. There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generate both health scores and short-lived dietary enthusiasms.Why is so much bad science published? A recent paper, titled “The Natural Selection of Bad Science”, published on the Royal Society’s open science website, attempts to answer this intriguing and important question. It says that the problem is not merely than people do bad science,but than out current system of career advancement positively encourages it.what is important is not truth, but inflationary process at work: (47) Nowadays anyone applying for a research post has to have published twice the number of papers than would have been required for the same post only 10 years ago. Never mind the quality,then count the number.(48)Attempts have been made to curd this tendency,for example by trying to incorporate some measure of quality as well as quantity into the assessment of anapplicant’s papers. This is the famed citation index,that is to say the number of times a paper has been quoted else where in the scientific literature the assumption being that an important paper will be cited more often than one of small account.(49) This would be reasonable if it were not for the fact that scientist can easily arrange to cite themselves in their future publicat or get associates to do so for them in return for similar favours.Boiling down an individual’s output to simple metrics, such as number of publications or journal impacts,entails considerable saving in time,energy and ambiguity.Unfortunate the long-term costs of using simple quantitative metrics to assess researcher merit are likely to be quite great.(50) If we are serious about ensuring that our science is both meaningful and reproducible ,we must ensure that our institutions encourage that king of science.Section III: WritingPart ADirections:Suppose you are working for the “aiding Rural Primary School”project of your university.
