Together, more Americans watch them than attend church or vote in presidential elections.Like it or not, they are America’s preeminent means of announcing itself to the world; we can share our ideals with hundreds of millions of our friends (and enemies) around the planet.Of the two events, one emphasizes the spirit of collective effort, by gathering anonymous men in identical uniforms to sacrifice themselves for the shared ideals of the tribe. The other glorifies the exceptional individual, who is celebrated for the very beauty and talent that sets him or her apart from lesser members of the species. Virtually anywhere there is a television—in Afghanistan, in Uruguay—these grand pageants are watched.The Super Bowl offers us a model of the kind of moral clarity that can be elusive on the playing fields of our lives. Its scores are settled on neutral territory, and its teams are governed by inflexible rules. There is little room for favoritism or sentimentality or emotional nuance. Football knows right from wrong. The Super Bowl shows us a world we all can agree on—one in which, far removed from the messiness of everyday life, strength and skill and practical intelligence prevail. Its champions earn their trip to Disneyland, because they prove themselves to be rulers of a magical kingdom.The Oscars, on the other hand, restore us to the commotion of the social world. They allow charm, money, fame and influence to matter. Sex and youth count above all, which is why, to the Oscars’ disgrace, women over 40 are rarely on display. Like Greek gods, the stars of the show are magnifications of the best and worst in all of us. No matter that they arrive bedecked with jewels or with a supermodel on their arm or with a complexion whose glow is suspiciously youthful, at the Oscars they are stripped to their most vulnerable selves, utterly at the mercy of the unpredictable. The Oscars give us unfiltered human spectacle, in which one is either called to the stage to meet with approval or forced to sit and contend with feelings of neglect and disappointment.36. The author holds that the Super Bowl and the Oscars are ________.A. two key events that draw most of the world’s attention to AmericaB. the moon and the sun to Americans as well as to the rest of the worldC. the rituals that are much more important than presidential electionsD. two important occasions for the realization of American dreams37. The Super Bowl and the Oscars are similar in ________.A. giving recognition of many personal sacrificesB. conferring an honor on certain achievementsC. encouraging an endeavor for national gloryD. placing a high priority on individual talent38. The kind of moral clarity showed in the Super Bowl most probably refers to a sense of ________.A. fair playB. social responsibilityC. self-disciplineD. collective identity39. According to the author, what we all agree on about the world shown by the Super Bowl is ________.A. the possibility that everyone can winB. the types of award to the championsC. the ways of showing one’s strengthD. the criteria for judging success40. The author emphasizes that the stars at the Oscars are ________.A. a symbol of human dignityB. images of Greek godsC. a mirror of ourselvesD. ideals of social elite41. According to the author, the Oscars offer us a human scene that shows a contrast between ________.A. trust and suspicionB. justice and injusticeC. wealth and povertyD. delight and dismayPassage TwoMore than 50 years ago, the psychologist Carl Rogers suggested that simply loving our children wasn’t enough. We have to love them unconditionally—for whothey are, not for what they do.As a father, I know this is a tall order, but it becomes even more challenging now that so much of the advice we are given amounts to exactly the opposite. In effect, we’re given tips in conditional parenting, which comes in two flavors: turn up the affection when they’re good, withhold affection when they’re not.Conditional parenting isn’t limited to old-school authoritarians. Some people who wouldn’t dream of spanking choose instead to discipline their young children by forcibly isolating them, a tactic we call “time out.” Conversely, “positive reinforcement” teaches children that they are loved only when they do whatever we decide is a “good job.” The primary message o f all types of conditional parenting is that children must earn a parent’s love.The child psychologist Bruno Bettelheim, who readily acknowledged that the version of negative conditional parenting known as time-out can cause “deep feelings of anxiety,” nevertheless endorsed it for that very reason. “When our words are not enough,” he said, “the threat of the withdrawal of our love and affection is the only sound method to impress on him that he had better conform to our request.”But research suggests tha t love withdrawal isn’t particularly effective at getting compliance, much less at promoting moral development. Even if we did succeed in making children obey us, is obedience worth the possible long-term psychological harm? Should parental love be used as a tool for controlling children?Albert Bandura, the father of the branch of psychology known as social learning theory, declared that unconditional love “would make children directionless and quite unlovable”—an assertion entirely unsupported by empirical studies. The idea that children accepted for who they are would lack direction or appeal is most informative for what it tells us about the dark view of human nature held by those who issue such warnings.In practice, unconditional acceptance should be accompanied by actively imagining how things look from the child’s point of view. Most of us would protest that of course we love our children without any strings attached. But what counts is how things look from the perspective of the children—whether they feel just as loved when they mess up or fall short.42. The author thinks what Carl Rogers suggested is ________.A. hard to practice todayB. unlikely to workC. harmful to childrenD. unpopular among parents43. In conditional parenting, when childr en don’t behave themselves, parents will ________.A. warn them of the consequencesB. give them a physical punishmentC. hold back their love of themD. stress their good behavior44. Bettelheim believes that time-out ________.A. is a useful means in some casesB. causes psychological disorderC. is an unconditional parenting styleD. causes children’s disobedience45. According to research, love withdrawal would ________.A. help children build a sense of independenceB. improve a long-term parent-child relationC. do little for fostering children’s ethical valuesD. cause children to develop an aggressive tendency46. In Albert Bandura’s opinion, children accepted for who they are would ________.A. disrespect their parentsB. lack a sense of responsibilityC. be inconsiderate of othersD. be disliked by others47. According to the passage, in practicing unconditional acceptance it is essential for parents to ________.A. show respect for children’s ideasB. set a moral example for childrenC. consider environmental factorsD. watch for children’s frustrationsPassage ThreeIt’s a Monday night at MIT, just a few weeks before final exams. Grad students Tegin Teich and Todd Schenk could be studying or relaxing. Instead, they’re hustling through a maze of basement hallways in search of notorious energy hogs: vending machines. The average soda dispenser consumes 3,500 kilowatts a year—more than four times the juice for a home refrigerator. To conserve electricity, MIT’s administrators have been installing devices called Vending Misers, which use motion detectors to turn off a machine’s lights and cooling systems when people aren’t nearby, cutting energy consumption by 50%. Trouble is, MIT isn’t exactly sure whereall its vending machines are located, or which ones already have the devices installed. So tonight it’s enlisted the MIT Energy Club to help figure it out.It’s just one event on the club’s very busy calendar. With 750 students, the four-year-old group is MIT’s fastest-growing extracurricular organization. Many of its members aim to build careers in “green tech” fields, and club events offer a chance to network and learn about the challenges and opportunities in emerging energy fields. In recent weeks, members had lunch with the U.S. Energy Secretary and toured a nuclear reactor. Others discussed national biofuel policy as part of a biweekly discussion held over beer and pizza at a local pub. Club members say the group exposes them to people and ideas from other disciplines; as a result, M.B.A. types become better versed in the science of climate change, while science geeks get comfortable reading business plans and understanding concepts like return on investment. In contrast to left-leaning campus environmentalists of a decade ago, who might have joi ned Greenpeace after school, “most of our members really believe in the power of the tools of capitalism to solve the problem,” says founder Dave Danielson, who earned a Ph.D. in material sciences last fall.Down in the basement at MIT, Teich and Schenk have found a group of eight vending machines. Four of them are hooked up to Vending Misers, but only one is functioning. “This is like wiring a stereo,” Schenk says, untangling wires to make the devices work. Teich climbs on top of a different machine to pick off layers of masking tape left over from a paint job that had rendered the gizmo’s sensor inoperable. “We probably just saved MIT $100” in reduced electricity bills, Teich says. It won’t save the planet—but every bit counts.48. Tegin Teich and Todd Schenk are ________.A. fourth-year students at MITB. members of the MIT Energy ClubC. good at machine maintenanceD. environmental engineering majors49. What does the passage say about Vending Misers?A. They failed to function well as expected.B. They were designed by the MIT Energy Club.C. They can detect the presence of people.D. They keep soda dispensers working consistently.50. Many members join club’s events for ________.A. career preparationsB. leisure enjoymentsC. answering Greenpeace’s callD. opposing nuclear energy51. The club has enabled its members to ________.A. help the government with decision-makingB. become brave enough to challenge the authoritiesC. decide to invest in biofuel in the futureD. acquire much interdisciplinary knowledge52. It is implied that Greenpeace ________.A. suffered some business lossesB. prefers to recruit science studentsC. is suspicious of capitalismD. was founded by Dave Danielson53. What does the last paragraph imply about “a paint job”?A. It caused a problem to the Vending Miser.B. It was needed for repairing the Vending Miser.C. It improved the Vending Miser’s efficiency.D. It was part of what the Vending Miser did.Passage FourNo doll outshines Barbie’s celebrity. If all the Bar bies and her family members—Skipper, Francie and the rest—sold since 1959 were placed head to toe, they would circle the Earth more than seven times. And sales boomed in 2009, when the fashion doll celebrated her 50th birthday on March 9th.Barbie starred at an array of global events honouring her milestone, including a glamorous affair at New York’s Fashion Week in February. On her birthday, Mattel, the company that makes her, launched a souvenir doll honouring the original Barbie in her black-and-white striped swimsuit and perfect ponytail. It was available for purchase only that one day. Another Golden Anniversary doll targets collectors. Barbie fans planned hundreds of events, including the National Barbie Doll Collectors Convention in Washington, DC, which was sold out.When Ruth Handler created Barbie in 1959, a post-war culture and economy thrived but girls still played with baby dolls. These toys limited the imagination; so Handler introduced Barbie the Teen-Age Fashion Model, named after her daughter, Barbara. Jackie Kennedy soon walked onto the world stage and Barbie already had a wardrobe fit for a first lady. Barbie bestowed on girls the opportunity to dream beyond suburbia, even if Ken (Barbie’s fictional boyfriend) at times tagged along.Barbie entranced Europe in 1961 and now sells in 150 countries. Every second three Barbies are sold around the world. Her careers are myriad—model, astronaut, Olympic swimmer, palaeontologist and rock star, along with 100 others, includingpresident. Like any political candidate, controversy hit Barbie in 1992 when Teen Talk Barbie said “Math class is tough” and girls’ education became a national issue. She has been banned (in Saudi Arabia), tortured (by pre-teen girls, according to researchers at the University of Bath’s School of Management) and fattened (in 1997).Feminists continue to batter Barbie, claiming that her beauty and curves treat women as objects. But others see her as a pioneer trendsetter, crashing the glass ceiling long before Hillary Clinton cracked it.High-tech entertainment now attracts girls and Barbie also faces fierce competition from various copycats including the more fashionable, but less charming, Bratz dolls. The Bratz suffered a setback in 2008. Mattel sued MGA Entertainment, Bratz’s producer, for copyright infringement. A judge awarded Mattel $100m in damages.54. According to Paragraph One, Barbie ________.A. was born earlier than the dolls of any other brandsB. has long been number one in the world of dollsC. has beaten other dolls in sales 7 times since 1959D. was once taken aboard a spaceship circling the earth55. To celebrate Barbie’s 50th birthday, ________.A. a Barbie fan club was set up in Washington, DCB. the original Barbie was displayed in New YorkC. fashion shows were held worldwide on March 9thD. Barbies based on its original design appeared on the market56. Ruth Handler created Barbie in the hope that it would ________.A. dress as attractively as Jackie Kennedy didB. encourage girls to become fashion modelsC. help girls generate new ideas and wishesD. become her daughter’s constant companion57. We can infer from Paragraph 4 that Barbie used to ________.A. cause a debate in the U.S. about girls learning mathB. act as a role model in more than 100 occupationsC. face denial by the parents of many pre-teen girlsD. become fatter to cater to the overweight girls58. Feminists hate Barbie mostly because it symbolizes women’s ________.A. material comfortsB. sexual attractionC. political powerD. multiple talents59. According to the passage, MGA Entertainment ________.A. lost a fortune by losing a lawsuitB. sold a toy cat to compete with BarbieC. beat traditional Barbie with hi-techD. filed a lawsuit against MattelPassage FiveAs he has done frequently over the last 18 months, Andy Roost drove his blue diesel Peugeot 205 onto a farm, where signs pointed one way for “eggs” and another for “oil.”He unscrewed the gas cap and chatted casually as Colin Friedlos, the proprietor, poured three large jugs of used cooking oil—tinted green to indicate environmental benefit—i nto the Peugeot’s gas tank.Mr. Friedlos operates one of hundreds of small plants in Britain that are processing, and often selling to private motorists, used cooking oil, which can be poured directly into unmodified diesel cars, from Fords to Mercedes.The global recession and the steep drop in oil prices have now killed many of those large refining ventures. But smaller, simpler ones like Mr. Friedlos’s are moving in to fill the void with their direct-to-tank product, with a flood of offers of free oil from restaurants.Used cooking oil has attracted growing attention in recent years as a cleaner, less expensive alternative to fossil fuels for vehicles. In many countries, including the United States, the oil is collected by companies and refined into a form of diesel. Some cities use it in specially modified municipal buses or vans. And the occasional environmentalist has experimented with individually filtering the oil and using it as fuel.Peder Jensen, a transport specialist at the European Environment Agency, said that cooking oil fuel was “feasible” for diesel engines—Rudolf Diesel predicted that his engine, patented in the 1890s, would run on it—and that it was, “from an environmental point of view, a good idea, taking this waste and making it useful.”Others disagree. Stuart Johnson, manager of engineering and environment at V olkswagen of America, called putting raw vegetable oil in cars “a bad idea” and said, “We don’t recommend it.” The inconsistent quality of cookin g oil fuel, he said, means that “it may contain impurities and it may be too viscous,” especially for newer, more complex diesel engines with injection systems.None of that seems to stir concern in Mr. Nicholson, the Welsh entrepreneur. He said. “There is a lot of resistance,” he said, “to putting something into your preciouscar that you brewed in the kitchen sink.”60. What is true about Andy Roost with respect to using cooking oil fuel for his diesel Peugeot?A. He’s been relying on it.B. He’s just started to try it.C. He’s keen on its green color.D. He’s curious about its effect.61. Unlike those large refining ventures, Mr. Friedlos’s plant ________.A. has been enjoying an economic revivalB. operates for protecting the environmentC. produces its product at a very low costD. has switched to serve private motorists62. As to the advantage of used cooking oil over fossil fuels, the former is ________.A. based on greater sources of raw materialB. more easily processed into a form of fuelC. purer so that it is better for diesel enginesD. used more widely in the world as car fuel63. According to the passage, Rudolf Diesel was ________.A. an environmentalistB. a car ownerC. an engine designerD. a car producer64. Some people oppose the use of cooking oil fuel because it may ________.A. give little help to environmental protectionB. pose a threat to some fossil fuel businessesC. do damage to some kinds of diesel enginesD. contain things harmful to the user’s health65. Mr. Nicholson thinks that the negative opinions about the use of used cooking oil are ________.A. understandableB. unimaginableC. unreasonableD. unacceptableSection B ( 20 minutes, 10 points)Direction:In each of the following passages, five sentences have been removed fromthe original text.

Two thirds rated character and attitude as very important, whereas only 3 per cent considered university degrees to be a real asset. 66) ________Historically, it can be summarised like this: on the one hand the self-educated leaders of small businesses have viewed graduates as time-wasting and costly upstarts, while graduates have sneered at the provincial mindset and paltry pay of the non-corporate office.But according to David Bishop, of the Federation of Small Businesses, it has got more to do with practical issues. “Because of th eir size, small businesses look for generalists with broader responsibilities rather than specialists,” he says. “They are not like a major employer with hundreds of employees each assigned a specific role.”Take IT, for example. 67) ________Certainly, there is resistance within the SME (small and medium-sized enterprises) community to employing graduates. The most frequently cited reasons reported by owner managers are: perceived high costs, worries about recruitment, retention and the graduate’s commitm ent, and concern about the high risk of recruiting graduates who are seen as inexperienced and often too academic.68) ________“Recruitment is a challenge in terms of competition and costs when you can’t offer the package of an international bank, but gra duates are valuable because they are on top of innovative research and development.”69) ________Afzal Akram, chairman of Business Link for London, says that small businesses are beginning to realise the potential employee resources found in universities.“In today’s business environment, people are the real differentiator, so getting the best is crucial. Tapping the graduate recruitment market allows small businesses to access candidates with excellent skills, training and education, who are hungry and mo tivated.”70) ________They undertake projects that benefit the host business, ranging from website design, marketing and accounting system implementation to product development.。

Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth.Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It's that simple."The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New Y ork Times article.21. What does the passage say about asteroids and meteoroids?A. They are heavenly bodies different in composition.B. They are heavenly bodies similar in nature.C. There are more asteroids than meteoroids.D. Asteroids are more mysterious than meteoroids.22. What do scientists say about the collision of an asteroid with Earth?A. It is very unlikely but the danger exists.B. Such a collision might occur once every 25 years.C. Collisions of smaller asteroids with Earth occur more often than expected.D. It's still too early to say whether such a collision might occur.23. What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?A. It sounds practical but it may not solve the problem.B. It may create more problems than it might solve.C. It is a waste of money because a collision of asteroids with Earth is very unlikely.D. Further research should be done before it is proved applicable.24. We can conclude from the passage that _.A. while pushing asteroids off course nuclear weapons would destroy the worldB. asteroids racing across the night sky are likely to hit Earth in the near futureC. the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetimeD. workable solutions still have to be found to prevent a collision of asteroids with Earth.25. Which of the following best describes the author's tone in this pass age?A. Optimistic.B. Critical.C. Objective.D. Arbitrary.Passage 2Believe it or not,optical illusion (错觉) can cut highway crashes.Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形)painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.Now the American Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japan's success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatest-curves, exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bar.Chevrons, scientists say,not only give drivers the impress ion that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.26. The passage mainly discusses .A. a new way of highway speed controlB. a new pattern for painting highwaysC. a new approach to training driversD. a new type of optical illusion27. On roads painted with chevrons drivers tend to feel that .A. they should avoid speed-related hazardsB. they are driving in the wrong laneC. they should slow down their speedD. they are approaching the speed limit28. The advantage of chevrons over straight, horizontal bars is that the former .A. can keep drivers awakeB. can cut road accidents in halfC. will have a longer effect on driversD. will look more attractive29. The American Association Foundation for Traffic Safety plans to .A. try out the Japanese method in certain areasB. change the road signs across the countryC. replace straight horizontal bars with chevronsD. repeat the Japanese road patterns30. What does the author say about straight, horizontal bars painted across roads?A. They are falling out of use in the United States.B. They tend to be ignored by drivers in a short period of time.C. They are applicable only on broad roads.D. They cannot be applied successfully to traffic circles.Passage 3There are a number of formats for reporting research, such as articles to appear in journals, reports addressed to funding agencies, theses or dissertations as part of the requirements for university degrees, and papers to be presented at conferences. These formats differ from one another mostly in their purposes and the audiences whom they address. We will now briefly describe them.The journal article is a way of reporting research for professional journals or edited collections. The research is reporting in a brief, yet informative way, focusing mostly on the main features of the research such as the purpose, review of the literature ( often referred to as "background" ), procedures used for carrying out the research accompanied by tables, charts, and graphs, and interpretations of the results ( often referred to as discussion).The content and emphasis of the journal article will vary according to the intended readers (research or practitioners) and it is important for the researcher to be aware of the background and interest of the readers of the journal. Articles intended to be read by practitioners will emphasize the practical implications and recommendations of the research, while articles intended to be read by researchers will describe in detail the method used to collect data, the construction of data collection procedures, and the techniques used for analyzing the data. It is important for the novice researcher to be aware of the fact that articles submitted to journals go through a process of evaluation by experts who make a judgment and recommend whether they should be published or not.The thesis or dissertation is a format for reporting research which graduate students write as part of fulfilling the requirements for an advanced academic degree. The student is expected to describe in great detail all the phases of the research so it can be examined and evaluated carefully by the reader. Thus the thesis or dissertation includes the purpose and significance of the study, the rationale, a thorough review of the literature, detailed information as to the research tools and the procedures involved in their development, a description of data analysis and the results, and an interpretation of the results in the form of conclusions, implications, and recommendation. Thisdetailed description of the process of the research is needed to provide the professors with an indication of the student's ability to carry out research.The conference paper is a way of reporting research at conferences, seminars and colloquia. At such meetings research papers are usually presented orally. They are similar to the research 'article since research is reported in a concise, yet informative way, focusing on the most essential elements of the research. Handouts and transparencies can also accompany the presentations. As with the research article, here too, the content and emphasis of the oral report will depend to a large extent on the type of audience present at the meeting .and whether they are researchers or practitioners.31. The best title for this passage could beA. Types of Research ReportsB. Types of Journal ArticlesC. Writing of research ReportsD. Writing of Different Artic les32. The common aspect for the journal articles, theses and conference papers lies in thatA. they are all for the practitionersB. they are all to be read by researchersC. they are all for being publishedD. they are all forms of reporting research33. We can distinguish those research reports from each other mainly throughA. their writing style and lengthB. their aims and possible audiencesC. their presented places and timeD. their content and purposes34. Which of the following statements is NOT mentioned in this passage?A. Both journal articles and conference papers are reported in a brief and informative way.B. All the theses or dissertations and conference papers are reported in spoken languages.C. Both the journal articles and conference papers are influenced greatly by the intended receivers.D. The various formats of research reports may be presented in different ways.35. How can a professor evaluate a student's capability of implementing the research?A. By concentrating on the main factors like the purpose, background, procedures and discussion.B. By emphasizing the practical implications and recommendations of the research.C. By focusing on the detailed description of the process of the research such as the tools, procedures, the process of data analysis, the results, conclusions, etc.D. By noticing the detailed method used to collect the data, the construction of the data collection procedures, the techniques for analyzing the date and results, etc.Passage 4In recent years, many Americans of both sexes and various ages have become interested in improving their bodies. They have become devoted to physical fitness. The need to exercise has almost become compulsive with many persons who have a strong desire to be more physically fit.By nature, Americans are enthusiastic and energetic about their hobbies and pastimes. They apply this enthusiasm, and energy to jogging/running. As a result, there are running clubs to join andmany books and magazines to read about running.The desire to be physically fit is explained by a "passion" for good health. The high rate of heart attacks in the 1960s caused an increase on the part of the public in improving the human body.Middle-aged men especially suffer from heart attacks. Thus, they are one group strongly interested in more physical exercise. In fact, many doctors encourage their patients to become more physically active, especially those who have sedentary jobs. It is interesting to note that the rate of heart attacks began to decrease in the 1970s and it is still decreasing.Physical fitness currently enjoys a favored role in the United States. It is a new "love" that many Americans have cherished. Will it last long? Only time will tell or until another "new passion" comes along.36. In recent years, many Americans have become interested in improving their bodies becauseA. they are enthusiastic about their hobbies and pastimesB. they have a strong desire to be more physically fitC. there are many running clubs to joinD. there are many books and magazines to read about running37.

Write your translation on the ANSWER SHEET (2).The fact known to us is that war, different from what many people believe it to be, is not completely an outcome of" humanity". Otherwise,war and violence among people would exist in all the human history or ahnost all societies. However, this is not the truth. Archaeologists' investigation results seem to suggest that men lived quite a peaceful life long ago. For example, among ancient French cave drawings which were earlier than 10, 000 B. C., there were no pictures describing people fighting with each other. This indicates that, in that early period of mankind, fight among people was comparatively rare.In a certain way, this discovery is not surprising at all:in the world of animals, it's rare for one to prey on another of its own species. They do kill other kinds of animals, but not their own. Like most animals, the proportion of inner violence among early human beings was relatively small. Therefore, war is not the inherent outcome of humanity but that of certain social and cultural conditions.PART VI Writing(15 points)Directions:A.

北京航空航天大学考博英语模拟试卷6(题后含答案及解析)题型有:1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionOne silly question I simply cannot tolerate is “How do you feel? “ Usually the question is asked of a man in action-a man walking along the street, or busily working at his desk. So what do you expect him to say? He’ll probably say, “Fine, I ‘m all right.” But you have put a bug a his ear—maybe now he is not sure. If you are his good friend, you may have seen something on his face, or in his walk, that he overlooked that morning. It makes him worrying a little. He looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else, “How do you feel? “Every question has its time and place. It’s perfectly acceptable, for instance, to ask “How do you feel? “ if you are visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to take a train or sitting at his desk working, it’s no time to ask him that silly question. When George Bernard Shaw, the famous British writer of plays was in his eighties, someone asked him , “How do you feel? “ Shaw put him in his place. “When you reach my age,” he said, “either you feel all right or you are dead.”1.According to the writer, greetings, such as “How do you feel? “_____.A.show one’s consideration for othersB.are a good way to make friendsC.are proper to ask a man in actionD.generally make one feel uneasy正确答案:D解析:结合全文的内容,可知正确答案为D项。

(Rossum's Universal Robots), published in 1920.[38] The play begins in a factory that makes artificial people called robots, though they are closer to the modern ideas of androids, creatures who can be mistaken for humans. They can plainly think for themselves, though they seem happy to serve. At issue is whether the robots are being exploited and the consequences of their treatment.Karel Čapek himself did not coin the word. He wrote a short letter in reference to an etymology in the Oxford English Dictionary in which he named his brother, the painter and writer Josef Čapek, as its actual originator.[38]In an article in the Czech journal Lidové noviny in 1933, he explained that he had originally wanted to call the creatures laboři ("workers", f rom Latin labor) or dělňasi (from Czech dělníci - "workers"). However, he did not like the word, and sought advice from his brother Josef, who suggested "roboti". The word robota means literally "corvée", "serf labor", and figuratively "drudgery" or "hard work" in Czech and also (more general) "work", "labor" in many Slavic languages (e.g.: Slovak, Polish, Macedonian, Ukrainian, archaic Czech). Traditionally the robota was the work period a serf (corvée) had to give for his lord, typically 6 months of the year. The origin of the word is the Old Church Slavonic rabota "servitude" ("work" in contemporary Bulgarian and Russian), which in turn comes from the Indo-European root *orbh-.[39] Serfdomwas outlawed in 1848 in Bohemia, so at the time Čapek wrote R.U.R., usage of the term robota had broadened to include various types of work, but the obsolete sense of "serfdom" would still have been known.[40] It is not clear from which language Čapek took the radix "robot(a)". This question is not irrelevant, because its answer could help to reveal an original Čapek´s conception of robots. If from the modern Czech language, the notion of robot should be understood as an …automatic serf“ (it means a subordinated creature without own will). If from e.g. Slovak (Karel Čapek and his brother were frequent visitors of Slovakia which in this time was a part of Czechoslovakia, because their father MUDr. Antonín Čapek from 1916 worked as a physician in Trenčianske Teplice.[41]), the word robot would simply mean a …worker“ which is a more universal and neutral notion. The aspect of pronunciation probably also played a role in Čapek's final decision: In non-Slavic languages it is easier to pronounce the word robot than dělňas or laboř.The word robotics, used to describe this field of study, was coined by the science fiction writer Isaac Asimov. Asimov created the "Three Laws of Robotics" which are a recurring theme in his books. These have since been used by many others to define laws used in fact and fiction. Introduced in his 1942 short story "Runaround" the Laws state the following:“ 1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.2. A robot must obey any orders given to it by human beings, except where suchorders would conflict with the First Law.3. A robot must protect its own existence as long as such protection does not conflictwith the First or Second Law说明:文章源自Etymology of Robot From Wikipedia, the free encyclopedia。

一、选择题,从括弧中选择一个最合适的答案。
(本题共15小题,每小题各2分,共计30分)。
1.在得出某种商品的个人需求曲线时,下列哪个因素是变化的?( ) A .个人收入 B .个人偏好C .其他商品的价格D .商品本身的价格 【答案】D 【解析】个人需求曲线是指在不同价格下个别消费者愿意购买数量的曲线,表示价格与商品的需求量之间成反方向变动的关系,因此商品本身的价格是内生的。
2.若消费者张某只准备购买两种商品X 和Y ,X 的价格为10,Y 的价格为2。
若张某买了7个单位的X 和3个单位的Y ,所获得的边际效用值分别为30个单位和20个单位,则( )。
A .张某获得了最大效用B .张某应增加X 的购买,减少Y 的购买C .张某应增加Y 的购买,减少的X 购买D .张某要想获得最大效用,需要借钱 【答案】C【解析】消费者效用最大化条件为://x x y y MU P MU P =。
题中//x x y y MU P MU P <,说明消费者张某没有获得最大效用。
根据商品边际效用递减规律,如果增加对Y 的购买,y MU 减小,减少对Y 的购买,x MU 增加,效用水平将增加。
3.己知某企业的生产函数Q =Q 为产量,L 和K 分别为劳动和资本),则( )。
A .生产函数是规模报酬不变B .生产函数是规模报酬递增C .生产函数是规模报酬递减D .企业处于内部经济阶段 【答案】A【解析】柯布-道格拉斯生产函数中的参数α和β的经济含义是:α为劳动所得在总产量中所占的份额,ß为资本所得在总产量中所占的份额。

已知有三个管摔碎,求三个力分别有各类管的概率。
2、全概率和贝叶斯的题,简单题。
3、求矩估计和极大似然估计。
貌似需要用到二阶矩估计才能做出来。
和考前做到的某数学模拟题类似。
4、X服从正态分布,在可靠性工程上在u<3西格玛时,若用来当寿命随机变量,需要大于零,所以需要修正,修正后的密度函数为K*f(x),求K。

Persistent sub-replacement fertility eventually translates into fewer workers relative to retirees,which puts tremendous strains on public coffers and the economy as a whole.Indeed,one recent study finds that almost half of the recent run-up in public debt in the West can be attributed to rapid aging over the last two decades.Even China may see its sky-high growth“come down to earth in the next few decades as its work force shrinks”because of its one-child policy,as Carlos Cavalle and I argued in a recent report.The Sustainable Demographic Dividend.By contrast,a recent Rand study suggests that“In dia will have more favorable demographics than China”over the next few decades,insofar as its work force is poised to grow.In fact,the Rand study suggests that India may be able to use this demographic advantage to outpace China's economic growth rates by the end of the century.Finally,it’s not just fertility that matters;it’s also marriage.At least in the West,children are more likely to acquire the human and social capital they need to thrive in the modern economy when they are raised in an intact, married family,In the U.S.,for instance,children are more likely to graduate from highschool,complete college and be gainfully employed as young adults if they were raised in an intact,married family.And around the globe,men are more likely to give their work their fullest effort and attention when they are married;this is one reason men worldwide enjoy“marriage premiums”in their income,ranging from about14 percent(Mexico)to19percent(UnitedStates)to35percent(Russia).So,at least when it comes to men,research suggests that marriage has important implications for worker productivity.The bottom-line message is that what happens in the home does not stay at home;rather,the size of families,and their stability and quality,has important implications for the health of the global economy.Questions21to25are based on the passage.21.The main idea of this passage is that_________.A.women should bear more children in order to boost the economy.B.both marriage and fertility affect a country’s economy.C.marriage has important implications for worker productivity.D.India will outpace China’s economic growth rate by the end of the century.22.One reason that the world’s leading economies are facing fiscal challenges is that______.A.there is a global economic crisis in recent years.B.there are fewer babies,and consequently,people spend less on many commodities.C.people in these countries have fewer children than needed to replace the population for many years.D.there are tremendous strains on public coffers and the economy as a whole.23.“...its work force is poised to grow”(para.3)probably means____________.A.its work force pauses to grow.B.its work force continues to grow fast.C.its work force continues to grow steadily.D.its work force grows slowly.24.From the passage we know that_________.A.children from an intact,married family are more likely to have a better life.B.the more people a country has,the stronger economy it will have.C.the health of the global economy depends entirely on individual families.D.men are likely to work harder when they are going to have children.25.According to the passage,all the following can affect economy EXCEPT_____________.A.the size of families.B.the stability of families.C.the quality of families.D.men and women ratio within the families.Passage2We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them.But we have realized only recently that the identity of each sex is not so easy to pin down,and that definitions evolve in accordance with different types of culture known to us,that is,scientific discoveries andideological revolutions.Our nature is not considered as immutable,either socially or biologically.As we approach the beginning of the21st century,the substantial progress made in biology and genetics is radically challenging the roles,responsibilities and specific characteristics attributed to each sex,and yet,scarcely twenty years ago,these were thought to be“beyond dispute”.We can safely say,with a few minor exceptions,that the definition of the sexes and their respective functions remained unchanged in the West from the beginning of the19th century to the1960s.The role distinction,raised in some cases to the status of uncompromising dualism on a strongly hierarchical model,lasted throughout this period,appealing for its justification to nature,religion and customs alleged to have existed since the dawn of time.The woman bore children and took care of the home.The man set out to conquer the world and was responsible for the survival of his family,by satisfying their needs in peacetime and going to war when necessary.The entire world order rested on the divergence of the sexes.Any overlapping or confusion between the roles was seen as a threat to the time-honored order of things.It was felt to be against nature,a deviation from the norm.Sex roles were determined according to the“place”appropriate to each.Women’s place was,first and foremost, in the home.The outside world,i.e.workshops,factories and business firms,belonged to men.This sex-based division of the world(private and public)gave rise to a strict dichotomy between the attitudes,which conferred on each its special identity.The woman,sequestered at home,“cared,nurtured and conserved”.T o do this,she had no need to bedaring,ambitious,tough or competitive.The man,on the other hand,competing with his fellow men,was caught up every day in the struggle for survival,and hence developed those characteristics which were thought natural in a man.Today,many women go out to work,and their reasons for doing so have changed considerably.Besides the traditional financial incentives,we find ambition and personal fulfillment motivating those in the most favorable circumstances,and the wish to have a social life and to get out of their domestic isolation influencing others. Above all,for all women,work is invariably connected with the desire for independence.Questions26to30are based on the passage.26.It is only in recent years that we have recognized that______.A.there is almost no clue to the identity of both sexes.B.the role distinction between different sexes is conspicuous.C.the different definitions of sexes bears on the development of culture.D.the progress of civilization greatly influences the role definitions of sexes.27.From paragraph1we can infer that it is now possible for women to embark on a career because______.A.the change in sex roles is out of the question.B.women’s lib has been going on for many years.C.ideas about the roles of women have been changing.D.the expansion of sciences scarcely remolds the women’s roles.28.The author believes that sex discrimination in the West before the1960s was______.A.preferable.B.prevalent.C.presumable.D.precedent.29.According to the fourth paragraph,the author seems to think that______.A.female passivity is natural.B.men and women are physically identical.C.men are born competitive and aggressive.D.some different sex identity is acquired.30.According to the author,which of the following is the most important reason for women to go to work?A.Wish to claim their rights and freedom.B.Ambition and self-fulfillment.C.Financial incentives.D.Desire for a social life.Passage3BBC’s Casualty programme on Saturday evening gave viewers a vote as to which of two patients should benefit from a donation.But it failed to tell us that we would not need to make so many life-and-death decisions if we got to grip with the chronic organ shortage.Being pussyfooting around in its approach to dead bodies,the Government is giving a kicking to some of the most vulnerable in our society.One depressing consequence of this is that a significant number of those on the waiting list take off to foreign countries to purchase an organ from a living third-world donor,something that is forbidden in the United Kingdom.The poor have no option but to wait in vain.The Human Tissue Authority’s position on the retention of body parts for medical research after a post-mortem examination is equally flawed.The new consent forms could have been draftedby some evil person seeking to stop the precious flow of human tissue into the pathological laboratory.The forms are so lengthy that doctors rarely have time to complete them and,even if they try,the wording is so graphic that relatives tend to leg it before signing.In consequence,the number of post mortems has fallen quickly.The wider worry is that the moral shortsightedness evident in the Human Tissue Act seems to infect every facet of the contemporary debate on medical ethics.Take the timid approach to embryonic stem cell research.The United States,for example,refuses government funding to scientists who wish to carry out potentially ground-breaking research on the surplus embryos created by IVF treatment.Senators profess to be worried that embryonic research fails to respect the dignity of“potential persons”.Rarely can such a vacuous concept have found its way into a debate claiming to provide enlightenm ent.When is this “potential”supposed to kick in?In case you were wondering,these supposedly precious embryos are at the same stage of development as those that are routinely terminated by the Pill without anyone crying.Thankfully,the British Government has refused the position of the United States and operates one of the most liberal regimes in Europe,in which licences have been awarded to researchers to create embryos for medical research.It is possible that,in years to come,scientists will be able to grow organs in the lab and find cures for a range of debilitating diseases.The fundamental problem with our approach to ethics is our inability to separate emotion from policy.The only factor that should enter our moral and legal deliberations is that of welfare,a concept that is meaningless when applied to entities that lackself-consciousness.Never forget that the research that we are so reluctant to conduct upon embryos and dead bodies is routinely carried out on living,pain-sensitive animals.Questions31to35are based on the passage.31.What has caused the chronic organ shortage?A.a decrease in donation ratesB.inefficient governmental policyC.illegal trade in human organsD.news media's indifference32.The expression“pussyfooting around”(Line3,Paragraph1)might mean______________.A.unfairB.hesitantC.secretD.strict33.The moral shortsightedness is revealed in the fact that___________.A.the government has stopped the experiment on human tissueB.the donation consent forms are difficult to understandC.the Human Tissues Act is an obstacle to important medical researchD.embryonic research shows disregard for human life34.To which of the following is the author most likely to agree?A.The rich and the poor are equal in the face of death.B.More scientists are needed for the medical advancement.C.There is a double standard in medical ethics.D.The dead deserve the same attention as the living.35.The author is most critical of______.A.the mediaB.doctorsC.U.S.LegislatorsD.the British governmentPassage4When a disease of epidemic proportions rips into the populace,scientists immediately get to work,trying to locate the source of the affliction and find ways to combat it.Oftentimes,success is achieved,as medical science is able to isolate the parasite,germ or cell that causes the problem and finds ways to effectively kill or contain it.In the most serious of cases,in which the entire population of a region or country may be at grave risk,it is deemed necessary to protect the entire population through vaccination,so as to safeguard lives and ensure that the disease will not spread.The process of vaccination allows the patient's body to develop immunity to the virus or disease so that,if it is encountered,one can ward it off naturally.To accomplish this,a small weak or dead strain of the disease is actually injected into the patient in a controlled environment,so that his body's immune system can leam to fight the invader /doc/75b0b238a98271fe900ef90f.html rmation on how to penetrate the disease's defenses is transmitted to all elements of the patient's immune system in a process that occurs naturally,in which genetic information is passed from cell to cell.This makes sure that,should the patient later come into contact with the real problem,his body is well equipped and trained to deal with it,having already done so before.There are dangers inherent in the process,however.On occasion,even the weakened version of the disease contained in the vaccine proves too much for the body to handle,resulting inthe immune system succumbing,and, therefore,the patient's death.Such is the case of the smallpox vaccine,designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers.Approximately1in10,000people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it.Thus,if the entire population of the United States were to receive the Smallpox Vaccine today, 3000Americans would be left dead.Fortunately,the smallpox virus was considered eradicated in the early1970s,ending the mandatory vaccination of all babies in America.In the event of a reintroduction of the disease,however,mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination.The process,which is truly a mixed blessing,may indeed hide some hidden curses.Questions36to40are based on the passage.36.The best title for the text may be____________.A."Vaccinations:A Blessing or A Curse"B."Principles of Vaccinations"C."Vaccines:Methods and Implications"D."A Miracle Cure under Attack"37.What does the example of the Smallpox Vaccine illustrate?A.The passible negative outcome of administering vaccines.B.The practical use of a vaccine to control an epidemic disease.C.The effectiveness of vaccines in eradicating certain disease.D.The method by which vaccines are employed against the disease.38.The phrase"ward it off naturally"(Paragraph2)mostprobably means______________.A.dispose of it naturally.B.fight it off with case.C.see to it reluctantly.D.split it up properly.39.Which of the following is true according to the text?A.Saving the majority would necessarily justify the death of the minority.B.The immune system can be trained to fight weaker versions of a disease.C.Mandatory vaccinations are indispensable to the survival of the populace.D.The process of vaccination remains a mystery to be further resolved.40.The purpose of the author in writing

北京航空航天大学考博英语模拟试卷1(题后含答案及解析)题型有:1. Reading Comprehension 2. Structure and V ocabulary 3. Cloze 4. English-Chinese Translation 5. WritingReading ComprehensionUnless we spend money to spot and prevent asteroids (小行星)now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids (流星)that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands whose orbits put them on a collision course with Earth. Buy $ 40 million worth of new telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’ll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap. Is it worth it? Two things experts consider when judging any risk are : 1) How likely the event is ; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. “If we don’t take care of these big asteroids, they’ll take care of us,”says one scientist. “It’s that simple. “The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.1.What does the passage say about asteroids and meteoroids?A.They are heavenly bodies different in composition.B.They are heavenly bodies similar in nature.C.There are more asteroids than meteoroids.D.Asteroids are more mysterious than meteoroids.正确答案:B解析:依据文章第二段第1行可以判断出两者性质相似只是体积不同,排除A项;文中并无两者数量上的比较,排除C项;也没有涉及D项的内容。

Persistent sub-replacement fertility eventually translates into fewer workers relative to retirees,which puts tremendous strains on public coffers and the economy as a whole.Indeed,one recent study finds that almost half of the recent run-up in public debt in the West can be attributed to rapid aging over the last two decades.Even China may see its sky-high growth“come down to earth in the next few decades as its work force shrinks”because of its one-child policy,as Carlos Cavalle and I argued in a recent report.The Sustainable Demographic Dividend.By contrast,a recent Rand study suggests that“India will have more favorable demographics than China”over the next few decades,insofar as its work force is poised to grow.In fact,the Rand study suggests that India may be able to use this demographic advantage to outpace China's economic growth rates by the end of the century.Finally,it’s not just fertility that matters;it’s also marriage.At least in the West,children are more likely to acquire the human and social capital they need to thrive in the modern economy when they are raised in an intact, married family,In the U.S.,for instance,children are more likely to graduate from high school,complete college and be gainfully employed as young adults if they were raised in an intact,married family.And around the globe,men are more likely to give their work their fullest effort and attention when they are married;this is one reason men worldwide enjoy“marriage premiums”in their income,ranging from about14 percent(Mexico)to19percent(United States)to35percent(Russia).So,at least when it comes to men,research suggests that marriage has important implications for worker productivity.The bottom-line message is that what happens in the home does not stay at home;rather,the size of families,and their stability and quality,has important implications for the health of the global economy.Questions21to25are based on the passage.21.The main idea of this passage is that_________.A.women should bear more children in order to boost the economy.B.both marriage and fertility affect a country’s economy.C.marriage has important implications for worker productivity.D.India will outpace China’s economic growth rate by the end of the century.22.One reason that the world’s leading economies are facing fiscal challenges is that______.A.there is a global economic crisis in recent years.B.there are fewer babies,and consequently,people spend less on many commodities.C.people in these countries have fewer children than needed to replace the population for many years.D.there are tremendous strains on public coffers and the economy as a whole.23.“...its work force is poised to grow”(para.3)probably means____________.A.its work force pauses to grow.B.its work force continues to grow fast.C.its work force continues to grow steadily.D.its work force grows slowly.24.From the passage we know that_________.A.children from an intact,married family are more likely to have a better life.B.the more people a country has,the stronger economy it will have.C.the health of the global economy depends entirely on individual families.D.men are likely to work harder when they are going to have children.25.According to the passage,all the following can affect economy EXCEPT_____________.A.the size of families.B.the stability of families.C.the quality of families.D.men and women ratio within the families.Passage2We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them.But we have realized only recently that the identity of each sex is not so easy to pin down,and that definitions evolve in accordance with different types of culture known to us,that is,scientific discoveries and ideological revolutions.Our nature is not considered as immutable,either socially or biologically.As we approach the beginning of the21st century,the substantial progress made in biology and genetics is radically challenging the roles,responsibilities and specific characteristics attributed to each sex,and yet,scarcely twenty years ago,these were thought to be“beyond dispute”.We can safely say,with a few minor exceptions,that the definition of the sexes and their respective functionsremained unchanged in the West from the beginning of the19th century to the1960s.The role distinction,raised in some cases to the status of uncompromising dualism on a strongly hierarchical model,lasted throughout this period,appealing for its justification to nature,religion and customs alleged to have existed since the dawn of time.The woman bore children and took care of the home.The man set out to conquer the world and was responsible for the survival of his family,by satisfying their needs in peacetime and going to war when necessary.The entire world order rested on the divergence of the sexes.Any overlapping or confusion between the roles was seen as a threat to the time-honored order of things.It was felt to be against nature,a deviation from the norm.Sex roles were determined according to the“place”appropriate to each.Women’s place was,first and foremost, in the home.The outside world,i.e.workshops,factories and business firms,belonged to men.This sex-based division of the world(private and public)gave rise to a strict dichotomy between the attitudes,which conferred on each its special identity.The woman,sequestered at home,“cared,nurtured and conserved”.To do this,she had no need to be daring,ambitious,tough or competitive.The man,on the other hand,competing with his fellow men,was caught up every day in the struggle for survival,and hence developed those characteristics which were thought natural in a man.Today,many women go out to work,and their reasons for doing so have changed considerably.Besides the traditional financial incentives,we find ambition and personal fulfillment motivating those in the most favorable circumstances,and the wish to have a social life and to get out of their domestic isolation influencing others. Above all,for all women,work is invariably connected with the desire for independence.Questions26to30are based on the passage.26.It is only in recent years that we have recognized that______.A.there is almost no clue to the identity of both sexes.B.the role distinction between different sexes is conspicuous.C.the different definitions of sexes bears on the development of culture.D.the progress of civilization greatly influences the role definitions of sexes.27.From paragraph1we can infer that it is now possible for women to embark on a career because______.A.the change in sex roles is out of the question.B.women’s lib has been going on for many years.C.ideas about the roles of women have been changing.D.the expansion of sciences scarcely remolds the women’s roles.28.The author believes that sex discrimination in the West before the1960s was______.A.preferable.B.prevalent.C.presumable.D.precedent.29.According to the fourth paragraph,the author seems to think that______.A.female passivity is natural.B.men and women are physically identical.C.men are born competitive and aggressive.D.some different sex identity is acquired.30.According to the author,which of the following is the most important reason for women to go to work?A.Wish to claim their rights and freedom.B.Ambition and self-fulfillment.C.Financial incentives.D.Desire for a social life.Passage3BBC’s Casualty programme on Saturday evening gave viewers a vote as to which of two patients should benefit from a donation.But it failed to tell us that we would not need to make so many life-and-death decisions if we got to grip with the chronic organ shortage.Being pussyfooting around in its approach to dead bodies,the Government is giving a kicking to some of the most vulnerable in our society.One depressing consequence of this is that a significant number of those on the waiting list take off to foreign countries to purchase an organ from a living third-world donor,something that is forbidden in the United Kingdom.The poor have no option but to wait in vain.The Human Tissue Authority’s position on the retention of body parts for medical research after a post-mortem examination is equally flawed.The new consent forms could have been drafted by some evil person seeking to stop the precious flow of human tissue into the pathological laboratory.The forms are so lengthy that doctors rarely have time to complete them and,even if they try,the wording is so graphic that relatives tend to leg it before signing.In consequence,the number of post mortems has fallen quickly.The wider worry is that the moral shortsightedness evident in the Human Tissue Act seems to infect every facet of the contemporary debate on medical ethics.Take the timid approach to embryonic stem cell research.The United States,for example,refuses government funding to scientists who wish to carry out potentially ground-breaking research on the surplus embryos created by IVF treatment.Senators profess to be worried that embryonic research fails to respect the dignity of“potential persons”.Rarely can such a vacuous concept have found its way into a debate claiming to provide enlightenment.When is this “potential”supposed to kick in?In case you were wondering,these supposedly precious embryos are at the same stage of development as those that are routinely terminated by the Pill without anyone crying.Thankfully,the British Government has refused the position of the United States and operates one of the most liberal regimes in Europe,in which licences have been awarded to researchers to create embryos for medical research.It is possible that,in years to come,scientists will be able to grow organs in the lab and find cures for a range of debilitating diseases.The fundamental problem with our approach to ethics is our inability to separate emotion from policy.The only factor that should enter our moral and legal deliberations is that of welfare,a concept that is meaningless when applied to entities that lack self-consciousness.Never forget that the research that we are so reluctant to conduct upon embryos and dead bodies is routinely carried out on living,pain-sensitive animals.Questions31to35are based on the passage.31.What has caused the chronic organ shortage?A.a decrease in donation ratesB.inefficient governmental policyC.illegal trade in human organsD.news media's indifference32.The expression“pussyfooting around”(Line3,Paragraph1)might mean______________.A.unfairB.hesitantC.secretD.strict33.The moral shortsightedness is revealed in the fact that___________.A.the government has stopped the experiment on human tissueB.the donation consent forms are difficult to understandC.the Human Tissues Act is an obstacle to important medical researchD.embryonic research shows disregard for human life34.To which of the following is the author most likely to agree?A.The rich and the poor are equal in the face of death.B.More scientists are needed for the medical advancement.C.There is a double standard in medical ethics.D.The dead deserve the same attention as the living.35.The author is most critical of______.A.the mediaB.doctorsC.U.S.LegislatorsD.the British governmentPassage4When a disease of epidemic proportions rips into the populace,scientists immediately get to work,trying to locate the source of the affliction and find ways to combat it.Oftentimes,success is achieved,as medical science is able to isolate the parasite,germ or cell that causes the problem and finds ways to effectively kill or contain it.In the most serious of cases,in which the entire population of a region or country may be at grave risk,it is deemed necessary to protect the entire population through vaccination,so as to safeguard lives and ensure that the disease will not spread.The process of vaccination allows the patient's body to develop immunity to the virus or disease so that,if it is encountered,one can ward it off naturally.To accomplish this,a small weak or dead strain of the disease is actually injected into the patient in a controlled environment,so that his body's immune system can leam to fight the invader rmation on how to penetrate the disease's defenses is transmitted to all elements of the patient's immune system in a process that occurs naturally,in which genetic information is passed from cell to cell.This makes sure that,should the patient later come into contact with the real problem,his body is well equipped and trained to deal with it,having already done so before.There are dangers inherent in the process,however.On occasion,even the weakened version of the disease contained in the vaccine proves too much for the body to handle,resulting in the immune system succumbing,and, therefore,the patient's death.Such is the case of the smallpox vaccine,designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers.Approximately1in10,000people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it.Thus,if the entire population of the United States were to receive the Smallpox Vaccine today, 3000Americans would be left dead.Fortunately,the smallpox virus was considered eradicated in the early1970s,ending the mandatory vaccination of all babies in America.In the event of a reintroduction of the disease,however,mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination.The process,which is truly a mixed blessing,may indeed hide some hidden curses.Questions36to40are based on the passage.36.The best title for the text may be____________.A."Vaccinations:A Blessing or A Curse"B."Principles of Vaccinations"C."Vaccines:Methods and Implications"D."A Miracle Cure under Attack"37.What does the example of the Smallpox Vaccine illustrate?A.The passible negative outcome of administering vaccines.B.The practical use of a vaccine to control an epidemic disease.C.The effectiveness of vaccines in eradicating certain disease.D.The method by which vaccines are employed against the disease.38.The phrase"ward it off naturally"(Paragraph2)most probably means______________.A.dispose of it naturally.B.fight it off with case.C.see to it reluctantly.D.split it up properly.39.Which of the following is true according to the text?A.Saving the majority would necessarily justify the death of the minority.B.The immune system can be trained to fight weaker versions of a disease.C.Mandatory vaccinations are indispensable to the survival of the populace.D.The process of vaccination remains a mystery to be further resolved.40.The purpose of the author in writing this
