Symmetrical features, flawless skin, looks to be 22 years oldmarket bar, a woman lucky enough to have this face would turn enough heads to stir a breeze. But when Victor Johnston points and clicks, the face on his computer screen changes into a state of superheated, crystallized beau “You can see it. It’s just so extraordinary,” says Johnston, a professor of biopsychology at New University who sounds a little in love with his creation.The transformation from pretty woman to knee-weakening babe is all the more amazing because the changeswrought by Johnston’s software are, objectively speaking, quite subtle. He created the original face by digitally averaging 16 randomly selected female Caucasian faces. The changing program then exaggerated the ways in which female faces differ from male faces, creating, in human-beauty-science field, a“hyp grew a bit larger, the nose narrowed slightly and the lips plumped. These are shifts of just a few millimeters, but experiments in this country and Scotland are suggesting that both males and females find“averaged faces more beautiful.Johnston hatched this little movie as part of his ongoing study into why human beings find some people attractive and others homely. He may not have any rock-solid answers yet, but he is far from alone in attemptingto apply scientific inquiry to so ambiguous a subject. Around the world, researchers are marching into territory formerly staked out by poets and painters to uncover the underpinnings of human attractiveness.The research results so far are surprising—and humbling. Numerous studies indicate that human not be simply in the eye of the beholder or an arbitrary cultural artifact. It may be ancient and universal, wrought through ages of evolution that rewarded reproductive winners and killed off losers. If beauty is not truth, it mayskin may fascinate moviegoers because, at s ome deep level, itbe health and fertility: Halle Berry’s flawlesspersuades us that she is parasite-free.Human attractiveness research is a relatively young and certainly contentious field—th females, for example, is still hotly debated—but those on its front lines agree on one point: We wonidea that beauty is until we understand its source. As psychologist Nancy Etcoff puts it:“The“looks-ism” unimportant or a cultural construct is the real beauty myth. We have to understand beauty, or we will always be enslaved by it.”36.The woman described in the very beginning of the text is .A. in fact in her late twentiesB. Johnston’s ideal girlfriendC. a stunning beautyD. is a professional prostitute37. Victor Johnston synthesized a new face by combining the features of 16 .A. beautiful European womenB. different women around the worldC. casually chosen white womenD. ordinary western women38. Through a few tiny changes made by Johnston, the synthesized face became even more .A. masculineB. averageC. feminineD. neutral39.Victor Johnston has produced such an attractive face in order to .A. give his computer a beautiful screenB. study the myth of human attractivenessC. prove the human capacity to create beautiesD. understand why Caucasian faces are special40. Paragraph 4 suggests that human beauty may be .A. culturally differentB. a disease-free idolC. individual-dependentD. a world agreed value41.It’s a consensus among the researchers that humans are still unconscious of .A. why they look attractiveB. when attractiveness is importantC. how powerful beauty isD. what constitutes beautyPassage TwoIt’s becoming something of a joke along the Maine-Canada border. So many busloads of retired people crisscross the line looking for affordable drugs that the roadside stands should advertise,Lipitor. Coumalin.” Except, of course, that such a market in prescription drugs would be illegal.These senior long-distance shopping sprees fall in a legal gray zone. But as long as people cross the border with prescriptions from a physician and have them filled for no more than a three-month supply for personal use, customs and other federal officials leave them alone. The trip might be tiring, but people can save an average of 60 percent on the cost of their prescription drugs. For some, that’s the difference between tak doing without. “The last bus trip I was on six months ago had 25 seniors,” says Chellie Ping state senator and now president of Common Cause.“Those 25 people saved $19,000 on their supplies o Pingree sponsored Maine RX, which authorizes a discounted price on drugs for Maine residents who lackinsurance coverage. The law was challenged by drug companies but recently upheld by the U.S.Supreme Court.It hasn’t yet taken effect.Figuring out ways to spend less on prescription drugs has become a multifaceted national movement of consumers, largely senior citizens. The prescription drug bill in America is $160 billion annually, and people over 65 fill five times as many prescriptions as working Americans on average.“But they do it on he are half as good and on incomes that are half as large,” says Richard Evans, senior analyst at Sa an investment research firm. What’s more, seniors account for 20 percent of the voting public.little wonder that the May 19 Supreme Court ruling got the attention of drug manufacturers and It’spoliticians across the country. The often-over-looked state of 1.3 million tucked in the northeast comer of the country became David to the phar-maceutical industry’s Goliath. The face-off began three years ago legislators like Pingree began questioning why Maine’s elderly population had to take all those bus t42.The elderly Americans cross the Maine-Canada border in order to get drugs that are .A. sold wholesaleB. over the counterC. less expensiveD. tax-free43.We can learn from the second paragraph that .A. people can buy as many drugs for personal useB. the cross-border drug shopping has been out of the federal controlC. Chellie Pingree used to be one of the cross-border shoppers for drugsD. the cross-border shopping is the only way for some Americans to get drugs44. Maine Rx mentioned in Paragraph Two is a .A. billB. drug companyC. customs officeD. seniors society45. Most cross-border shoppers are retired people, rather than working Americans, because the former .A.have more leisure timeB.fill more prescriptionsC.mostly enjoy long tripsD.are fond of street shopping46. Politicians were interested in the May 19 Supreme Court ruling because .A. they couldn’t improve the well-being of the elderlyB. they couldn’t afford to ignore the elderly’s votesC. they saw the elderly as the greatest contributorsD. they saw the elderly as deserving a special care47. David and Goliath are names used to describe a situation in which_____.A. the two groups are evenly matched in strengthB. a more powerful group is fighting a less powerful groupC. a less powerful group is fighting a more powerful groupD. both of the two groups are losersPassage ThreeIt’s navel gazing time again, that stretch of the year when many of us turn our attention inward and think about how we can improve the way we live our lives. But as we embark on this annual ritual of introspection, we would do well to ask ourselves a simple question: Does it really do any good?The poet Theodore Roethke had some insight into the matter:“Self-contemplation is a curse tha old confusion worse.” As a psychologist, I think Roethke had a point, one that’s supported controlled psychological studies.In a study I conducted with Dolores Kraft, a clinical psychologist, and Dana Dunn, a social psychologist, people in one group were asked to list the reasons their relationship with a romantic partner was going the way it was, and then rate how satisfied they were with the relationship. People in another group were asked to rate their satisfaction without any analysis; they just gave their gut reactions.It might seem that the people who thought about the specifics would be best at figuring out how they really felt, and that their satisfaction ratings would thus do the best job of predicting the outcome of their relationships.In fact, we found the reverse. It was the people in the“gut feeling”group whose ratings they were still dating their partner several months later. As for the navel gazers, their satisfaction ratings did not predict the outcome of their relationships at all. Rather, too much analysis can confuse people about how they really feel.Self-reflection is especially problematic when we are feeling down. Research by Susan Nolen Hoeksema, a clinical psychologist at Yale University, shows that when people are depressed, ruminating on their problems makes things worse.For years it was believed that emergency workers like police officers and firefighters should undergo a debriefing process to focus on and relive their experiences; the idea was that this would make them feel better and prevent mental health problems down the road. But did it do any good? In an extensive review of the research, a team led by Richard McNally, a clinical psychologist at Harvard, concluded that debriefing procedures havelittle benefit and might even hurt by interrupting the normal healing process. People often distract themselvesfrom thinking about painful events right after they occur, and this may be better than mentally reliving the events.48.According to the author, why do people tend to look inward at the end of a year?A. They want to know if they get prepared for the future.B. They consider it beneficial to their future lives.C. They pay too much attention to their self-improvement.D. They overemphasize their progress in the past year.49.The author agrees with Theodore Roethke on that_____.A. people need self-reflection when they feel blueB. people are reluctant to confide in romantic partnersC. people may be more depressed by recalling the painful pastD. people would become sober when clearing up the confusions50.The findings of the study on the satisfaction ratings in romantic relationship reveal that_____.A. meditation can keep the relationship at its peakB. retrospection helps people feel satisfied with the partnerC. specific analysis can foretell the future of the relationshipD. thinking about details makes one uncertain about the relationship51.The phrase“the navel gazers”in Paragraph 5 refers to people who_____.A. boast of their own successB. hesitate in romantic relationshipsC. worry about their futureD. focus on their past52. Which of the following is the best way to help firefighters relieve their trauma?A. Leave them alone to adjust their emotions.B. Provide them with consultation about their jobs.C. Help them figure out what has happened.D. Discuss with them how to do it better next time.53.According to the passage, _____can help people get over a painful experience.A. pouring out their feelings about itB. distracting their attention from itC. discussing it with specialistsD. recalling the specificsPassage FourPublic speaking fills most people with dread. Humiliation is the greatest fear; self-exposure and failing to appeal to the audience come a close second. Women hate it most, since girls are pressurized from an early age to be concerned with appearances of all kinds.Most people have plenty of insecurities, and this seems like a situation that will bring them out. If parents, teachers or peers mocked your foibles as a child, you fear a repeat. If you were under pressure to be perfect, you are terrified of failing in the most public of ways.While extroverts will feel less fear before the ordeal, it does not mean they will necessarily do it better. Some very shy people manage to shine. In fact, personality is not the best predictor of who does it well. Regardless of what you are like in real life, the key seems to be to act yourself.Actual acting, as in performing the scripted lines of a character other than yourself, does not do the job. While politicians may limit damage by having carefully rehearsed, written screeds to speak from, there is alwaysa hidden awareness among the audience that the words might not be true.Although, as Earl Spencer proved at his sister Princess Diana’s funeral, it is possible both to word and to act naturally, a script rarely works and it is used as a crutch by most people. But, being yourself doesn’t work either. If you spoke as if you were in your own kitchen, it would be too authentic, too unaware of the need to communicate with an audience.I remember going to see British psychiatrist RD Laing speak in public. He behaved like a seriously odd person, talking off the top of his head. Although he was talking about madness and he wrote on mental illness, he seemed to be exhibiting rather than explaining it.The best psychological place from which to speak is an unselfconscious self-consciousness, providing theas psychologists call it, is very satisfying. illusion of being natural. Studies suggest that this state of“flow”,Whether in normal life or making speeches, the key is to remind yourself that, contrary to what your teachers or parents may have implied, your best is good enough. In the zone, a strange place of authentic falsehood and shallow depth, play is possible.54.For most people the biggest fear for public speaking is_____.A. looking foolishB. failing in wordsC. not attracting attentionD. appearing pressurized55.According to the passage shy people_____A. have greater difficulty than extrovert onesB. are not good at actingC. may well do a good job in a speechD. are better speakers in the public eye56.A successful speech maker is usually one who_____.A. can act naturallyB. makes careful preparationsC. rehearses adequatelyD. can get across easily57.The example of the British psychiatrist in Paragraph 6 shows a failure in_____.A. showing modesty in publicB. talking about one’s own tradeC. presenting the topic logicallyD. communicating with the audience58.“Shallow depth” in the last paragraph implies_____.A. being yourself in the performanceB. trying to look seriousC. pretending to be well-preparedD. being seemingly knowledgeable59.From the passage, we get the impression that public speaking is something_____.A. hard to do wellB. scary but manageableC. tough but rewardingD. worthwhile to challengePassage FiveAfrican American women’s search for societal acceptance often encompasses struggle between natural a socially constructed ideas of beauty. As an essential component in traditional African societies, cosmetic modification is ritualized to emphasize natural features of blackness. Defined by social occasion such as childhood development to maturity, indicators of marital status or the group to which you belong, beautificationof the hair and body play an essential role. In our racially conscious society, presenting a physical image and being accepted is a complex negotiation between two different worlds.Hair is an outward expression of culture and heritage. It also represents a sense of personal style. In the search for the African American identity, blacks have undergone many different changes in hairstyle. Hairstyles are cultural classifiers of what African Americans consider beautiful. Hairstyles are a representation of the African American soul, all of their confidence and dignity show in how they present themselves on Sundays and on adaily basis.“Duringthe sixties, white American youth used their hair to make a variety of political and philosophical statements,”young blacks joined thereafter.“The natural hairstyle not only was eas but also gave African Americans a closer tie to their heritage. Natural style serves as a visible imprimatur of blackness; a tribute to group unity; a statement of self-love and personal significance.”standards of beauty, black Americans halted the processes of using chemical straighteners or hot irons.A woman talks about her struggle.“I remember battling with the idea of going natural for several year never had the courage because every time I pictured myself with my natural hair, I never saw beauty. Now myhair is natural, thick and healthy.”African American women are finding confidence within themselves t their hair naturally and feel beautiful about it. Many contemporary African Americans are avoiding high maintenance and feeling confident in their natural beauty.It was a different story in the past. African Americans were pressed. Shame was the motivation behind blacks losing their roots and ethnic identity. By being brainwashed into believing black people arepeople are“superior”African Americans have mutilated and adjusted their bodies to try to lookstandards.Hair is as different as the people it belongs to. People are finally recognizing that beauty is what helps to create our individual identities. Ultimately, individual confidence shapes and strengthens the culture of theAfrican American community.60.The first paragraph tells us that African Americans_____.A. have been trying hard to be socially acceptedB. have been changing their value about beautyC. have maintained their identity of traditional AfricansD. have modified their hairstyles to fit into the society61. What kind of problem do African Americans face in society?A. They would look ugly if they don’t change their hairstyles.B. Their natural image may not be accepted by white Americans.C. They would never find a suitable hairstyle in the hair salons.D. Their cultural heritage may risk being abandoned by themselves.62.The word“imprimatur”in Paragraph 2 most probably means_____.A. dislikeB. betrayalC. approvalD. suspicion63. African Americans stopped using chemical straighteners or hot irons because_____.A. they reversed the attitude the white people had towards themB. they started to see beauty in their thick curly hairC. they feel good and comfortable in being differentD. they accepted the white standards of beauty64.Why did some African Americans accept the white standards of beauty?A. Because they tried to keep socially fashionable.B. Because they did not have their own standards of beauty.C. Because they were not well educated as white Americans.D. Because they wanted to become part of the mainstream.65.To African Americans, hair is a significant indicator of_____.A. their cultural identityB. their aesthetic tasteC. their social recognitionD. their challenge against the societySection B (20 minutes, 10 points)Passage OneFrancois Jacob wrote that“an age or culture is characterized less by the extent of its knowledge than b66 .nature of the questions it puts forward.” Admittedly, the most brilliant cultures are developed during the days of knowledge acquirement. 67 . Many convincing examples can be given when looking back to the cultural development of these countries. The most influential Chinese culture flourished during Tang Dynasty, which was established a thousand years ago. This influence can be traced by the word“Tang Street”, another name for Chinatown. And it was du time that the Chinese acquired more knowledge than they had before.68 However, when compared with the knowledge people have acquired and are acquiring today, the knowledge of the ancient Tangs and Arabs is unquestionably limited. But in all history books, the cultures of the Tang Dynasty and the ancient Arab are introduced in detail, while the cultures of the Peopleand the Arab League are seldom mentioned.69 . For instance, the ancient Greeks and Romans’knowledge about nature was definitely insu but they are still recognized as the founders of the most magnificent ages and cultures in human history because the questions put forward and thought about by them were profound and meaningful. In the works of the Greeks and Romans represented by The Iliad, The Odyssey and The Aeneid, the questions concerning life and death, love and hatred, benevolence and malevolence and individual and society are raised. People can always draw inspirations from Achilles’s different attitudes towards death in the Iliad and the Odyssey and Aeneas from love and glory. 70 .The importance of an era or civilization can never be diminished because of its lack of knowledge. The essence of an age or culture should be the exploration in the spiritual world and the thoughtful questions posed.A. The Arabian culture thrived when the Arabians learnt the application of arithmetic and created Arabic numbers.B. These remain the questions people face, contemplate and discuss till today.C. In general, cultures are developed during the time of knowledge acquirement.D. This statement reveals that the nature of an epoch or civilization is decided by the things that are thought about, rather than the things that are already known.E. This is probably a universal truth for all countries and nations that boast impressive histories.F. Compared with knowledge, the questions put forward are more significant in an age or culture.Passage TwoOver the past two decades, the lives of American women have undergone unparalleled change. The VirginiaSlims Opinion Poll has chronicled that change in national surveys conducted six times since 1970. 71 .One of the most striking findings of the 1990 Virginia Slims Opinion Poll is the degree of consensusthan conflict—in women’s and men’s attitudes about the changing roles of women. In many respects, thesexes agree. Men express strong and consistent support for women’s improved status in society.72 And they agree that the most tangible way in which they could help women balance jobs and family is to take on more household work.But men are also a major cause of resentment and stress for American women. 73 Now, a generation of sweeping change later, women’s expectations have outpaced the change in men’s behavior. Tok74 .dishes or the children no longer inspires women’s gratitude.Increasingly, the kitchen table has become that bargaining table. 75 Next to money, “how much mymate helps around the house”is the single biggest cause of resentment among women who are married or li as if married, with 52 percent citing this as a problem. Improvement in this area is one of the top things womencite when they consider what would make their lives better.A. There is evidence in the poll that waiting for men to live up to the ideal of equal responsibility is a major irritant for most women today.B. Together, these surveys provide a comprehensive picture of women’s changing status, and of the future.C. In 1970, most women were concerned about getting men to share household chores.D. They, like women, believe that sex discrimination remains an important problem in the workplace.E. Over the past three generations, expectationns of men as rulers and protectors of the household havechanged.F. Instead, as women contribute more to the family income, they expect in return a more equal division ofthe household responsibilities.PAPER TWOPART IV TRANSLATION(30 minutes, 15 points)As we enter the 21st century, the gap between the world’s rich and poor is widening, both with countries. 1)The vast majority of the world’s population is receiving an ever-decreasing share of its c wealth, while the share claimed by a few rich nations and individuals is steadily growing. In 2001 Forbesmagazine counted 538 billionaires with a total net worth of 1.7 trillion dollars, while the United Nations identified2.8 billion people surviving on less than two dollars a day. Overall, the richest 20 percent of the worldcontrol 86 percent of global income, while the poorest 20 percent control barely one percent.The impacts of this widening rich-poor gap are varied and worrisome. 2) They include environmental nations and individuals can afford to over-consume resources, while poorer nations and destruction—richerindividuals are forced to over-exploit the environment just to survive. They include migrationto move in search of adequate resources. And they include conflict—wealthier nations and individkeep what they have, while those suffering a lack of resources fight to obtain them. 3) Because poorer groups typically lack the assets and technology to conduct large-scale conventional war to obtain their goals, they often resort to low-intensity conflict and terrorism. The causes of this global disparity are diverse and complex, but include colonial era trading patterns that favor industrialized nations; the globalization of economies and economic structures, in which poor nations struggle to compete; a growing“digital divide”of access to information technology; inadequate governance and protection of law; and lack of access to education healthcare, and social safety nets, especially for women and girls.4) Individuals and nations need not remain in poverty indefinitely, however. With an awareness o f theinterdependence o f our modern world and a concerted political will, it is possible to reverse this trend that。

As a result, cultural scripts about marriage have undergone change. One of the more obvious 46 has occurred in the roles that women 47 • Women have moved into the world of work and have become adept at meeting expectations in that arena, 48 maintaining their family roles of nurturing and their family roles of nurturing and creating a(n) 49 that is a haven for all family members. 50 many women experience strain from trying to “do it alf\ they often enjoy the increased 51 that can result from playing multiple roles. As womens roles have changed, changing expectations about merTs roles have become more 52 • Many men are relinquishing their major responsibility 53 the family provider. Probably the most significant change in men's roles, however, is in the emotional 54 of family life. Men are increasing 55 to meet the emotional needs of their families, 56 their wives.In fact, expectations about the emotional domain of marriage have become more significant for marriage in general. Research on 57 marriage has changed over recent decades points to the increasing importance of the emotional side of the relationship, and the importance of sharing in the "emotion work，，58 to nourish marriages and other family relationships. Men and women want to experience marriages that are interdependent, 59 both partners nurture each other, and encourage and promote each other.

He was John Styth Pemberton, born in 1833 in Knoxville, Georgia, eighty miles away. Sometimes known as Doctor, Pemberton was a pharmacist who, during the Civil War, led a cavalry troop under General Joe Wheeler. He settled in Atlanta in 1869, and soon began brewing such patent medicines as Triplex Liver Pills and Globe of Flower Cough Syrup. In 1885, he registered a trademark for something called French Wine Coca-Ideal Nerve and Tonic Stimulant; a few months later he formed the Pemberton Chemical Company, and recruited the services of a bookkeeper named Frank M・ Robinson, who not only had a good head for figures but, attached to it, so exceptional a nose that he could audit the composition of a batch of syrup merely by sniffling it. In 1886-a year in which, as contemporary Coca-Cola officials like to point out, Conan Doyle unveiled Sherlock Holmes and France unveiled the Statue of Liberty-Pemberton unveiled a syrup that he called Coca-Cola- It was a modification of his French Wine Coca. He had taken out the wine and added a pinch of caffeine, and, when the end product tasted awful, had thrown in some extract of cola nut and a few other oils, blending the mixture in a three-legged iron pot in his back yard and swishing it around with an oar. He distributed it to soda fountains in used beer bottles, and Robinson, with his flowing bookkeeper's script, presently devised a label, on which "Coca-Cola" was written in the fashion that is still employed. Pemberton looked upon his mixture less as a refreshment than as a headache cure, especially for people whose headache could be traced to over-indulgence.On a morning late in 1886, one such victim of the night before dragged himself into an Atlanta drugstore and asked for a dollop of Coca-Cola. Druggists customarily stirred a teaspoonful of syrup into a glass of water, but in this instance the man on duty was too lazy to walk to the fresh-water tap, a couple of feet off. Instead, he mixed the syrup with some soda water, which was closer at hand. The suffering customer perked up almost at once, and word quickly spread that the best Coca-Cola was a fizzy one.61.What does the passage tell us about John Sty th Pemberton?A.He was highly respected by Atlantans.B.He ran a drug store that also sells wine.C.He had been a doctor until the Civil War.D.He made a lot of money with his pharmacy.62.Which of the following was unique to Frank M. Robinson, working with the Pemberton's Company?A.Skills to make French wine.B.Talent for drawing pictures.C.An acute sense of smell.D.Ability to work with numbers.63.Why was the year 1886 so special to Pemberton?A.He took to doing a job like Sherlock Holmes's.B.He brought a quite profitable product into being.C.He observed the founding ceremony of Statue of Liberty.D・ He was awarded by Coca-Cola for his contribution.64.One modification made of French Wine Coca formula wased beer bottles were chosen as containers.B.the amount of caffeine in it was increased.C.it was blended with oils instead of water.D.Cola nut extract was added to taste.65.According to the passage, Coca-Cola was in the first place prepared especially forA.the young as a soft drink・B.a replacement of French Wine Coca.C.the relief of a hangover.D・ a cure for the common headache.66.The last paragraph mainly tellsA.the complaint against the lazy shop-assistant.B.a real test of Coca-cola as a headache cure.C・ the mediocre service of the drugstore.D.a happy accident that gave birth to Coca-Cola.Passage TwoBetween 1833 and 1837, the publishers of a "penny press" proved that a low-priced paper, edited to interest ordinary people, could win what amounted to a mass circulation for the times and thereby attract an advertising volume that would make it independent. These were papers for the common citizen and were not tied to the interests of the business community, like the mercantile press, or dependent for financial support upon political party allegiance. It did not necessarily follow that all the penny papers would be superior in their handling of the news and opinion functions. But the door was open for some to make important journalistic advances.The first offerings of a penny paper tended to be highly sensational; human interest stories overshadowed important news, and crime and sex stories were written in full detail. But as the penny paper attracted readers from various social land economic brackets, its sensationalism was modified. The ordinary reader came to want a better product, too. A popularized style of writing and presentation of news remained, but the penny paper became a respectable publication that offered significant information and editorial leadership. Once the first of the successful penny papers had shown the way, later ventures could enter the competition at the higher level of journalistic responsibility the pioneering papers had reached.This was the pattern of American newspapers in the years following the founding of the New York Sim in 1833. The Sun, published by Benjamin Day, entered the lists against 11 other dailies. It was tiny in comparison; but it was bright and readable, and it preferred human interest features to important but dull political speechreports. It had a police reporter writing squibs of crime news in the style already proved successful by some other papers. And, most important, it sold for a penny, whereas its competitors sold for six cents. By 1837 the Sun was printing 30,000 copies a day, which was more than the total of all 11 New Yrok daily newspapers combined when the Sim first appeared. In those same four years James Gordon Bennett brought out his New York Herald(1835), and a trio of New York printers who were imitating Day's success founded the Philadelphia Public Ledger(1836) and the Baltimore Sun(1837). The four penny sheets all became famed newspapers.67.What does the first paragraph say about the "penny press?"A.It was known for its depth news reporting.B.It had an involvement with some political parties.C.It depended on the business community for survival.D.It aimed at pleasing the general public・68.In its early days, a penny paper oftenA.paid much attention to political issues.B.provided stories that hit the public taste.C.offered penetrating editorials on various issues.D.covered important news with inaccuracy.69.As the reader ship was growing more diverse, the penny paperA.improved its contentB.changed its writing style.C.developed a more sensational style.D.became a tool for political parties.70.The underlined word "ventures^ in Paragraph 2 can best be replaced byA.editors.B.reporters.C.newspapers.panies.71.What is true about the Philadelphia Public Ledger and the Baltimore SunlA.They turned out to be failures.B.They were later purchased by James Gordon Bennett.C.They were also founded by Benjamin Day.D.They became well-known newspapers in the U.S.72.This passage is probably taken from a book onA.the work ethics of the American media.B.the techniques in news reporting・C.the history of sensationalism in American media.D.the impact of mass media on American society.Passage ThreeForget what Virginia Woolf said about what a writer needs-a room of one's own. The writer she had in mind wasn't at work on a novel in cyberspace, one with multiple hypertexts, animated graphics and downloads of trancey, chiming music. For that you also need graphic interfaces, RealPlayer and maybe even a computer laboratory at Brown University. That was where Mark Amerika-his legally adopted name; don't ask him about his birth name-composed much of his novel Grammatron. But Grammatron isn't just a story. It，s an online narrative () that uses the capabilities of cyberspace to tie the conventional story line into complicated knots. In the four years it took to produce-it was completed in 1997-each new advance in computer software became another potential story device. “I became sort ofdependent on the industry：jokes Amerika, who is also the author of two novels printed on paper.“ThaFs unusal for a writer, because if you just write on paper the "technology" is pretty stable二Nothing about Grammatron is stable. At its center, if there is one, is Abe Golam, the inventor of Nanoscript, a quasi-mystical computer code that some unmystical corporations are itching to acquire. For much of the story, Abe wanders through Prague-23, a virtual "4city^ in cyberspace where visitors indulge in fantasy encounters and virtual sex, which can get fairly graphic. The reader wanders too, because most of Grammatron 9s 1,000-plus text screens contain several passages in hypertext. To reach the next screen, just double-click. But each of those hypertexts is a trapdoor that can plunge you down a different pathway of the story. Choose one and you drop into a corporate-strategy memo. Choose another and there's a XXX-rated sexual rant. The story you read is some sense the story you make.Amerika teaches digital art at the University of Colorado, where his students develop works that straddle the lines between art, film and literature. "I tell them not to get caught up in mere plot J he says. Some avant-garde writers-Julio Cortazar, Italo Calvino- have also experimented with novels that wander out of their author^ control. "But what makes the Net so exciting/7says Amerika, “is that you can add sound, randomly generated links, 3-D modeling, animation.” That room of one's own is turning into a fun house.73.The passage is mainly to tellA.differences between conventional and modern novels.B.how Mark Amerika composed his novel Grammatron.C・ common features of all modem electronic novels.D.why Mark Amerika took on a new way of writing.74.Why does the author ask the reader to forget what Virginia Woolf said about the necessities of a writer?A.Modern writers can share rooms to do the writing.B.It is not necessarily that a writer writes inside a room.C.Modem writers will get nowhere without a word processor.D.It is no longer sufficient for the writing in cyberspace.75.As an on-line narrative, Grammatron is anything but stable because itA.provides potentials for the story development.B.is one of the novels at (g ).C.can be downloaded free of charge.D.boasts of the best among cyber stories.76.By saying that he became sort of dependent on the industry, Mark Amerika meant thatA. he could not help but set his Grammatron and others in Industrial Revolution.B・ conventional writers had been increasingly challenged by high technology.C.much of his Grammatron had proved to be cybernetic dependent.D.he couldn't care less about new advance in computer software.77.As the passage shows, Grammatron makes it possible for readers toA.adapt the story for a video version.B.“walk in，，the story and interact with it.C.develop the plots within the author's control.D.steal the show and become the main character.78.Amerika told his students not toA.immerse themselves only in creating the plot.B.be captivated by the plot alone while reading. C・ be lagged far behind in the plot development.D.let their plot get lost in the on-going story.Passage FourIn 1993, a mall security camera captured a shaky image of two 10-year-old boys leading a much smallerboy out of a Liverpool, England, shopping center. The boys lured James Bulger, 2, away from his mother, who was shopping, and led him on a long walk across town. The excursion ended at a railroad track. There, inexplicably, the older boys tortured the toddler, kicking him, smearing paint on his face and pummeling him to death with bricks before leaving him on the track to be dismembered by a train. The boys, Jon Venables and Robert Thompson, then went off to watch cartoons.Today the boys are 18-year-old men, and after spending eight years in juvenile facilities, they have been deemed fit for release-probably this spring. The dilemma now confronting the English jsutice system is how to reintegrate the notorious duo into a society that remains horrified by their crimes and skeptical about their rehabilitation. Last week Judge Elizabeth Butler-Sloss decided the young men were in so much danger that they needed an unprecedented shield to protect them upon release. For the rest of their lives, Venables and Thompson will have a right to anonymity. All English media outlets are banned from publishing any information about their whereabouts or the new identities the government will help them establish. Photos of the two or even details about their current looks are also prohibited.In the U.S., which is harder on juvenile criminals than England, such a ruling seems inconceivable. "Wele clearly the most punitive in the industrialized world/9 says Laurence Steinberg, a Temple University professor who studies juvenile justice. Over the past decade, the trend in the U.S. has been to allow publication of ever more information about underage offenders. U.S. courts also give more weight to press freedom than English courts, which, for example, ban all video cameras.But even for Britain, the order is extraordinary. The victim's family is enraged, as are the ever eager British tabloids. "What right have they got to be given special protection as adults?97asks Bulger's mother Denise Fergus. Newspaper editorials next door. Says conservative Member of Parliament Humfrey Malins: Tt almost leaves you with the feeling that the nastier the crime, the greater the chance for a passport to a completely new life：'79.What (Kcurred as told at the beginning of the passage?A.2 ten-year-olds killed James by accident in play.B.James Bulger was killed by his two brothers.C.Two mischievous boys forged a train accident.D.A little kid was murdered by two older boys.80.According to the passage, Jon Venables and Robert ThompsonA.have been treated as juvenile delinquents.B.have been held in protective custody for their murder game.C・ were caught while watching cartoons eight years ago.D.have already served out their 10 years in prison・81.The British justice system is afraid that the two young men wouldA.hardly get accustomed to a horrifying general public.B.be doomed to become social outcasts after release.C.still remain dangerous and destructive if set free.D.be inclined to commit a recurring crime.82.According to the British courts, after their return to society, the two adults will beA.banned from any kind of press interview.B.kept under constant surveillance by police.C.shielded from being identified as killers.D.ordered to report to police their whereabouts.83.From the passage we can infer that a US counterpart of Venables or Thompson wouldA・ have no freedom to go wherever he wants.B.serve a life imprisonment for the crime.C.be forbidden to join many of his relatives.D.no doubt receive massive publicity in the U.S.84.As regards the mentioned justice ruling, the last paragraph mainly tells thatA.it is controversial as it goes without precedent.B.the British media are sure to do the contrary.C.Bulger^s family would enter all apeal against it.D.Conservatives obviously conflict with Liberals.Passage FiveCan the Internet help patients jump the line at the doctor's office? The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits'，between doctors at three big local medical groups and about 6,000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees wont have to skip work to tend to minor ailments or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your docotr in your hometown can be a big chunk of time," says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies.Doctors aren't clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid^ says Stirling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work.” In the pilot program, physicians will get $20 per online consultation, about what they get for a simple office visit.Doctors also fear they'll be swamped by rambling E-mails that tell everything but what's needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Cal if.-based start-up. Healinx's "Smart Symptom Wizard" questions patients and turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face-to-face visit.Can E-mail replace the doctor's office? Many conditions, such as persistent cough, require a stethoscope to discover what's wrong- and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor's groups in the pilot, believes the virtual doctor's visits offer a “very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic.The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet's record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Helainx/5 notes Michael Barrent, an analyst at Internet consulting firm Forester Research. If the “Web visits” succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren't satisfied, firgure on one more E-health start-up to stand down.85.The Silicon Valley employers promote the E-health program for the purpose ofA. rewarding their employees.B. gratifying the local hospitals.C.boosting worker productivity.D. testing a sophisticated technology.86.What can be learned about the on-line doctors' visits?A.They are a quite promising business-B.They are funded by the local government.C.They are welcomed by all the patients.D.They are very much under experimentation.87.Of the following people, who are not involved in the program?A・ Cisco System employees. B. Advice nurses in the clinic.C.Doctors at three local hospitals.D. Oracle executives.88.According to Paragraph 2, doctors are。

Hardly the qualities of a star, but they describethe deformed mouse that was the media darling at a recent science exhibition in Beijing. With a complex tissue structure in the shape of a human ear grafted on to its back, the rosy rodent was a stunning symbol of the serious strides China is making in the field of biotechnology.China is fast applying the latest life-science techniques learned from the West to aggressively pursue genome research. It's establishing its own centers of technical excellence to build a scientific base to compete directly with the United States and Europe. With a plentiful supply of smart young scientists at home and lots of interest abroad biotechnology is on the brink of a boom in China. And in the view of foreign scientists, Beijing is playing a clever hand, maximizing the opportunities open to them.For the moment, the cooperation exists mostly with Europe and the U.S. But Asia's other biotech leaders, Japan, Singapore and Korea, also are recognizing China's potential as an attractive low-cost base to conduct research. These partnerships—and China's advancement in the field of biotechnolo-gy—could help benefit the rest of Asia: China's rapid progress in improving crop yields will address food-security concerns in the region. In addition, China is more likely to focus on developing cheap technology that its predominantly poor population—and those of other Asian countries—can afford.There remain, however, serious barriers to the development of a strong biotech industry. Among them are a poor domestic legal framework, weak enforcement of intellectual-property rights and loose adherence to international standards. China is a signatory of the International Bio Safely Protocol, which should mean adherence to global standards governing the conduct of field trials. But some observers are skeptical. “The regulations look goo d, but I haven't met one scientist who believes they are being fully adhered to,” says a European science analyst.If shortcuts are taken, then some of the recent scientific achievements trumpeted in the official press may never make it to market. But no matter how strict lab test are, other problems lie in wait. For example, there is a number of tasks it would take years to fulfill in the patents office, says one lawyer, leaving innovators with little protection if they take a product to market in China.56. The mouse on display is most significant in that__________.A. it has an ear in the shape of a human earB. it is unusually small and ugly as a starC. it is the focus of the media at the exhibitionD. it indicates China's progress in biotechnology57. The phrase “on the brink of a boom” (in boldface in Paragraph 2) in thecontext means __________.A. having an edge in competitionB. in great demandC. on the way to successD. preparing for challenge58. In the field of biotechnology China is thought to__________.A. have been making an utmost effort learning from the WestB. have become a country among the advancedC. have been able to rival the United States and EuropeD. have launched a biotechnological revolution59. Japan, Singapore, and Korea will also be interested in cooperating withChina in biotechnology because__________.A. it has made extraordinary contributions to the worldB. it has large supplies of talents and advanced research centersC. its research focuses on the benefits of all Asian countriesD. its cooperation with the US and Europe proves profitable60. Science analysts are worried that China, in the course of biotech development,__________.A. might refuse to join efforts to adhere to global standardsB. may put too much emphasis on developing cheap technologyC. cannot afford to fulfill years of tasks in assessing patentsD. may not seriously follow the International Bio Safely Protocol61. As implied in the context, the shortcuts that might be taken include__________.A. publicizing recent achievements in the official pressB. the protection of innovators with their productsC. the violation of intellectual-property rightsD. making lab tests as strict as possiblePassage 2The sizzling streams of sunlight were just beautifully glimmering down on the crisp green schoolyard. Such a wonderful day that was. Nothing could have ruined it. Little Jimmy, since it was such a wonderful day, decided to go to the corner store and but himself a little treat. As Jimmy started walking over to the store, clouds flocked over the dazzling sun and the sudden pitch dark meant to trouble. On the other side of the road were three white boys from Jimmy's same school. Upon recognizing Jimmy, the boys ran over the street to where he was.“Hey Negro, what's up?” one of the white boys said.“Did your mamma pack you enough to eat today?” another hooted.“Just leave me alone,” Little Jimmy said.“Oh no, Jimmy's really getting pist off!?” the first boy retaliated.“Just shove off and let me be,” Jimmy answered.It is like this everyday, everywhere, and every time, people suffer discrimination. All because they have differences amongst each other. Different beliefs, different cultures, different skin colors, all of these act like building blocks to help construct what we know as Racism.Racism has become one of the many burdens amongst multi-cultural worlds like Canada and the States. Racism is a part of each every one of us. No doubt, we are all racist, but the term racism has been used too loosely. Racism has been mutated to such an extent that it could be a reason for war, a symbol of terrorism, and even an excuse for neglecting.Is that all there is to it? No actually it is just the beginning. Racism is just like warfare in which there is no shelter and nobody is neutral.Nobody is exempt form this demon. He has haunted us with a bitter curse. On one occasion I remember, nobody would play with me at school. I would walk around by myself and ask people if we could play together. Everywhere that I went, like the process of induction, everyone would avoid me, like two inducted poles with the same polarity, they would just shimmer off into the distance and continue to do whatever they're doing. Because of racial differences, they neglect me.People are afraid of the unknown, and it is this difference amongst people that spread rumors and distrust amongst people. Corrupting our thoughts and reasons, we get accustomed to thinking differences are omens. Amongst smaller kids, there is no difficulty in getting them to all play together. Their thoughts are not totally corrupted as others. Probably the demon has no time to bother with smaller children.62. With the description of the weather and Jimmy's feeling about it the authorintends to show that __________.A. what a happy world it is for humansB. what an innocent boy Jimmy wasC. what an unusual thing hat was to happen to JimmyD. what a wonderful world that people have ignored63. From the conversation with the three white boys, we learn that Jimmy__________.A. must have offended them beforeB. was a pleasant boy to be talked toC. was being humiliated for being blackD. must have got used to their behaviors64. According to the author, Racism__________.A. leads to a world with no varietyB. does not see the differences between culturesC. hinders the world's economic developmentD. does not tolerate coexistence of different cultures65. By saying “No doubt, we are all racist” (in boldface in Paragraph 3) theauthor admits that __________.A. we are all warlike by natureB. we all discriminate against other peoplesC. we are all proud of our own race and nationD. we all focus on the difference between races66. To be continued, the passage would probably be followed by a paragraphthat deals with __________.A. how children's thoughts are corrupted by racism as they growB. the author's far more miserable experience of being neglectedC. how the black people should unite to fight against the WhitesD. the education of smaller children to behave pleasantly to each other67. Which of the following can best describe the tone of teh passage?A. Provocative.B. Indignant.C. Sentimental.D. Sarcastic.Passage 3This week marks the 10th anniversary of the Alar apple scare, in which many American consumers were driven into a panic following the release of a report by an environmental organization claiming that apples containing the chemical Alar posed a serious health threat to preschoolers. The report was disseminated through a PR (Problem Report) campaign and bypassed any legitimate form of scientific peer review. Introduced to the American public by CBS“60 Minutes,”the unsubstantiated claims in the report led some school disricts to remove apples from their school lunch programs and unduly frightened conscientious parents trying to develop good eating habits for their children.Last month,Consumers Union released a report warning consumers of the perils of consuming many fruits and vegetables that frequentlycontained“unsafe” levels of pesticide residues. This was especially true for children, they claimed. Like its predecessor 10 years earlier, the Consumers Union report received no legitimate scientific peer review and the public's first exposure to it was through news coverage.Not only does such reporting potentially drive children for consuming healthful fruits and vegetables, the conclusions were based on a misleading interpretation of what constitutes a “safe” level of exposure. Briefly, the authors used values known as the “chronic reference doses.” set by the U. S. environmental Protection Agency, as their barometers of safely. Used appropriately, these levels represent the maximum amount of pesticide that could be consumed daily for life without concern. For a 70-year lifetime, for example, consumers would have to ingest this average amount of pesticide every day for more than 25,000 days. It is clear, as the report points out, that there are days on which kids may be exposed to more; it is also clear that there are many more days when exposure is zero. Had the authors more appropriately calculated the cumulative exposures for which the safety standards are meant to apply, there would have been no risks and no warnings.Parents should feel proud, rather than guilty, of providing fruits and vegetables for their children. It is well established that a diet rich in such foods decreases the risk of heart disease and cancer. Such benefits dramatically overwhelm the theoretical risks of tiny amounts of pesticides in food. So keep serving up the peaches, apples, squash, grapes and pears.68. In the Alar apple scare, many Americans were frightened because__________.A. scientists warned that apples were dangerousB. many school children became ill after eating applesC. it was reported that apples were harmful to healthD. apples were discovered to have too much pesticide69. The warning message about the Alar apple was given__________.A. by Consumers UnionB. by a health centerC. through an news agencyD. through the government70. The last month report parallels that on the Alar apple scare in that__________.A. neither really caused worry among the publicB. neither underwent a scientific peer reviewC. neither provided statistical supportsD. neither aimed for the public good71. The “chronic reference doses” (in boldfac e in Paragraph 3) refer to__________.A. the safe levels of pesticide exposureB. the amount of fruits one can safely eatC. one's digestive capacity for fruitsD. health values of fruits and vegetables72. With regard to the pesticides in food, this passage seems to argue that__________.A. parents should keeps their children from the food with pesticidesB. they should be applied to fruits and vegetables wit cautionC. more research needs to be done on their harmfulness to healthD. they are not as threatening as said to children most of the time73. The primary purpose of this passage is to explain that__________.A. not all reports on food are scientifically soundB. it is important for the public to know the risks of pesticidesC. vegetables and fruits can be harmful to children's healthD. there should be no public concern over pesticidesPassage 4Abortion. The word alone causes civil conversation to flee the room. This is largely because the prochoice and pro-life positions are being defined by their extremes, by those who scream accusations instead of arguments.More reasonable voices and concerns, on both sides of the fence, are given little attention.For example, pro-life extremists seem unwilling to draw distinctions between some abortions and others, such as those resulting from rape with an underage child. They would make no exception in the recent real-life case of a woman who discovered in her fifth month that her baby would be born dead due to severe disabilities.On the other hand, pro-choice extremists within feminism insist on holding inconsistent positions. The pregnant woman has an unquestionable right to abort, they claim. Yet if the biological father has no say whatsoever over the woman's choice, is it reasonable to impose legal obligations upon him for child support? Can absolute legal obligation adhere without some sort of corresponding legal rights?The only hope for progress in the abortion dialogue lies in the great excluded middle, in the voices of average people who see something wrong with a young girl forced to bear the baby of a rapist.Any commentary on abortion should include a statement of the writer's position. I represent what seems to b ea growing“middle ground” in pro-choice opinion. Legally, I believe in the right of every human being to medically control everything under his or her own skin. Many things people have a legal right to do, however, seem clearly wrong to me: adultery, lying to friends, walking past someone who is bleeding on the street. Some forms of abortion fall into that category. Morally speaking, my doubts have become so extreme that I could not undergo the procedure past the first three months and I would attempt to dissuade friends from doing so.Fanatics on both sides are using reprehensible and deceitful tactics. An honest dialogue on abortion must start by re-setting the stage, by denouncing the approaches that block communication.74. According to the passage, the pro-life and pro-choice positions on abortion are__________.A. complementary to each otherB. opposed to each otherC. similar in natureD. reconcilable in a way75. To a pro-life extremist,__________.A. all babies should be carried to termB. babies resulting form rape should not be bornC. deformed babies can be aborted when detectedD. an underage girl has no right to give birth76. According to the pro-choice position,__________.A. a pregnant woman cannot abort her baby if its father arees to keep itB. a pregnant woman has an absolute right of choice over an abortionC. the baby's father also has a say over its mother's choice of abortionD. the baby's father has an unalienable obligation to support the baby77. Who would insist that the baby be born whether or not it is the child of a rapist?A. The authorB. Average peopleC. A pro-choice advocateD. A pro-life extremist78. The author doubts the legal right to lie to friends as well as the one to__________.A. abort a fetus in its fifth monthB. view the photos of late-term abortionC. give birth to a baby in one's teenageD. dispose of what ever under one'sskin79. The author, as a “middle ground” person,__________.A. actually holds a mild pro-life opinionB. proposes that a rapist's baby never be bornC. advocates a serious dialogue on abortionD. denies the principle “a woman's body, a woman's right”Passage 5In the absence of optimism, we are left with nothing but critics, naysayers, and prophets of doom. When a nation expects the worst from its people and institutions, and its experts focus exclusively on faults, hope dies. Too many people spend too much tie looking down rather than up, finding fault with their country's political institutions, economic system, educational establishment, religious organizations, and—worst of all —with each other.Faultfinding expends so much negative energy that nothing is left over for positive action. It takes courage and strength to solve the genuine problems that afflict every society. Sure, there well always be things that need fixing. But the question is, Do you want to spend your time and energy tearing things down or building them up?The staging of a Broadway show could illustrate my point. Let's say a new production is about to open. A playwright has polished the script, investor have put up the money, and the theater ahs been rented. A director ahs been chosen, actors have been auditioned and selected, and the cast has been rehearsing for weeks. Set, lighting, and sound engineers have been hard at work. By the time opening night arrives, nearly a hundred people have labored tirelessly—all working long hours to make magic for their audience.On opening night ,four or five critics sit in the audience. If they pan it, the play will probably close in a matter if days or weeks. If they praise it, the production could go on for a long and successful run. In the end, success or failure might hinge on the opinion of a single person—someone who might be in a bad mood on opening night! What's wrong with this scene? In one sense, nothing. Critics have a legitimate role. The problem arises when we make critics our heroes or put them in control of our fate. When we empower the critic more than the playwright, something is wrong. It is much easier to criticize than to create. When we revere the critics of society, we eventually become a society of critics, and when that happens, there is no room left for constructive optimism.80. According to the author, critics usually__________.A. ignore minor imperfectionsB. overemphasize flawsC. see both sides of a coinD. pin their hopes onimprovements。

中国科学院(中科院)2012年3月考博英语真题分析 华慧考博王老师精解
中科院2012年3月份考博英语真题分析中科院试题考试题型变化不大，这一方面考生不必太过于担心，按照历年考试的难易程度以及考试题型进行针对性的练习，持之以恒，掌握正确的复习方法必将会通过考博英语这门考试。
总体来讲，中科院的英语题型分为以下几种：1、词汇题（10分，20题）2、完型填空（15分，15题）3、阅读理解（40分，40题）4、英译中（15分，5题）5、写作（20分，1题）这几种题型，相比考生都不是很陌生，在四六级考试和考研考试中都有过系统的练习。
但是有些不同的是中科院的考博英语题量阅读较大。
比如，在完型填空中有五篇，每篇设置六个题目，其中阅读理解中不但有传统的四选一选题理解题，还有七选五阅读理解题，而且七选五出现两篇，增大了大了试题的难度。
考生在平常的复习中需重视阅读理解题型，尤其是对阅读不是很拿手的同学应当提前下手，准备这一考试专项。
具体来说，2012年3月的考试内容中。
词汇题难度保持了原有的难度。
完型考试中出现科技说明的科普文章，主要讲了历史上的六次物种灭绝的情况，考察了考生逻辑能力和平常的知识的积累。
八篇阅读理解，分别考了真理及谬论情况；文化拍卖市场以及文化的需求；双语中英文学校；赡养90岁以上老人的社会伦理道德现象；收养儿童问题以及电梯事件和对孩子的教育问题。
通常为社会中常出现的现象或事件或热点问题。
翻译的主要内容也是社会伦理道德方面。
最后，作文考察了一道哲学思辨题，我认为中科院也是考察了考生的科技伦理和科技哲学观点，这对于以后意什么样的态度开展研究工作至关重要。
总之，中科院的考博英语难度较大，希望考生好好准备相关内容。
