1. 手机刷新了人与人的关系。
会议室门口通常贴着一条通告：请与会者关闭手机。
可是会议室里的手机铃声仍然响成一片。
我们都是普通人，并没有多少重要的事情。
尽管如此，我们也不会轻易关掉手机。
打开手机象征我们与这个世界的联系。
手机反映出我们的"社交饥渴症"。
最为常见的是，一个人走着走着突然停下来，眼睛盯着手机屏幕发短信。
他不在乎停在马路中央还是厕所旁边。
Few things have changed human relations as much as the cell phone has. It so happens that we often see a notice on a door to a conference room, "Please keep your cell phone off when a meeting is in session." We still, however, always hear the beeps resounding throughout the chamber. The prevalence of using the cell phone today reflects our "thirst for socialization" and symbolizes a connection between us and the outside world. We are therefore reluctant to turn it off, although few of us are VIPs, or those who have many urgencies to take immediate care of. So we often notice such a picture: a pedestrian, all of sudden, stops, his eyes fixed on the phone screen, to edit his messages, oblivious of all other things. Whether being on the road center or beside a toilet does not seem to bother him.2. We, the human species, are confronting a planetary emergency - a threat to the survival of our civilization that is gathering ominous and destructive potential even as we gather here. But there is hopeful news as well: we have the ability to solve this crisis and avoid the worst - though not all - of its consequences, if we act boldly, decisively and quickly.However, too many of the world's leaders are still best described in the words of Winston Churchill applied to those who ignored Adolf Hitler's threat: “They go on in strange paradox, decid ed only to be undecided, resolved to be irresolute, all powerful to be impotent.”So today, we dumped another 70 million tons of global-warming pollution into the thin shell of atmosphere surrounding our planet, as if it were an open sewer. And tomorrow, we will dump a slightly larger amount, with the cumulative concentrations now trapping more and more heat from the sun我们人类，正面临全球性的危机，我们的生存和文明受到威胁。

"These findings are troubling since, with afew 42 , such as professional basketball, no one could argue that height issomething essential required for job 43 ," Judge points out.Judge analyzed results of four large-scale studies in the US and Britain that followedthousands of people from childhood to adulthood, examining details of their work andpersonal lives. "If you take this 44 the course of a 30-year career, we're talkingabout literally hundreds of thousands of dollars of earnings 45 that a tall personenjoys," Judge said.Greater height boosted both subjective ratings of work performance--a supervisor's 46 of how effective someone is-- and 47 measures of performance--such assales volume.

At the University of Nevada at Las Vegas (UNLV) students photographedtest questions with their cellphone cameras and transmitted them to classmates. Theuniversity put in place a new examination-supervision system. "If they'd spend as muchtime studying, they'd all be A students," says Ron Yasbin, dean of the College ofSciences of UNLV.With a variety of electronic devices, American students find it easier to cheat. Andcollege officials find themselves in a new game of cat and mouse. They are trying to fightwould-be cheats in the exam season by cutting off Internet access from laptops, demanding the surrender of cellphones before tests or simply requiring that exams betaken with pens and paper."It is annoying. My hand-writing is so bad," said Ryan Dapremont, 21 who justfinished his third year at PepperdineUniversity in California. He had to take his examson paper. Dapremont said technology has made cheating easier, but plagiarism(剽窃) inwriting papers was probably the biggest problem. Students can lift other people's writingsoff the Internet without attributing them.Still, some students said they thought cheating these days was more a product of themindset, not the tools at hand. "Some people put too much emphasis on where they'regoing to go in the future, and all they're thinking about is graduate school and the nextstep," said Lindsay Nicholas, a third-year student at UCLA. She added that pressure tosucceed "sometimes clouds everything and makes people do things that they shouldn'tdo."Some professors said they tried to write exams for which it was hard to cheat,posing questions that outside resources would not help answer. Many officials said thatthey rely on campus honor codes. They said the most important thing was to teachstudents not to cheat in the first place.51. One student at UCLA was found cheating ________________.A. when he was loading his class notes into a handheld e-mail deviceB. when he was trying to tell the answers to his classmatesC. after the university put in place a new examination-supervision systemD. after his classmate reported his cheating to the authority52. According to Ron Yasbin, all the cheating students _____________.A. should be severely punished for their dishonestyB. didn't have much time to study before the examC. could get the highest grades if they had studied hard enoughD. could be excused because they were not familiar with the new system53. To win the new game of cat and mouse in examinations, the college officials have to______________.A. use many high-tech devicesB. cut off Internet access on campusC. turn to the oral exanimation formsD. cut off the use of high-tech devices54. According to Ryan Dapremont, ______________.A. examinations taken with pens and paper were useless in fighting cheatingB. his examination paper was under-graded because of his bad hand-writingC. cheating was more serious in writing papers than in examinationsD. it was more difficult for him to lift other people's writings off the Internet55. Which of the following is probably the most Significant measure to fight cheating?A. Putting less emphasis on where the students are going to go in the future.B. Letting students know that honesty is more important.C. Writing examinations for which it is hard to cheat.D. Setting up more strict campus honor codes.56. The best title of the passage might be_____________.A. Cheating Has Gone High-techB. Game of Cat and MouseC. A New Examination-supervision SystemD. Measures to Fight Against DishonestyPassage TwoTop marathon runners tend to be lean and light, star swimmers are long thighs withhuge feet and gold medal weightlifters are solid blocks of muscle with short arms andlegs. So, does your physical shape--and the way your body works--fit you for aparticular sport? Or does your body develop a certain way because of your chosen sport?"It's about 55:45, genes to the environment," says Mike Rennie, professor of clinicalphysiology at Britain's University of Nottingham Medical School. Rennie cites the caseof identical twins from Germany, one of whom was a long-distance athlete, the other apowerful sportsman, so, "They look quite different, despite being identical twins."Someone who's 1.5-meters tall has little chance of becoming an elite basketballplayer. Still, being over two meters tall won't automatically push you to Olympic gold."Unless you have tactical sense where needed, unless you have access to good equipment,medical care and the psychological conditions, and unless you are able to drive yourself through pain, all the physical strength will be in vain," said Craig Sharp, professor ofsports science at Britain's Brunel University.Jonathan Robinson, an applied sports scientist at the University of Bath's sportsdevelopment department, in southwest England, points to the importance of technique."In swimming only 5-10 per cent of the propelling force comes from the legs, sotechnique is vital."Having the right physique for the right sport is a good starting point. Seventeenyears ago, the Australian Institute of Sport started a national Talent Search Program,which searched schools for 14-16-year-olds with the potential to be elite athletes. One oftheir first finds was Megan Still, world champion rower. In 1987, Still had never pickedup an oar in her life. But she had almost the perfect physique for a rower. After intensivetraining, she won gold in women's rowing in the 1996 Atlanta Olympics.Other countries have followed the Australian example. Now the explosion of geneticknowledge has meant that there is now a search, not just for appropriate physique but alsofor "performance genes."57. It can be concluded from the passage that__________.A. physical strength is more important for sportspersons' successB. training conditions are more important for sportspersons' successC. genes are more important for sportspersons' successD. psychological conditions are more important for sportspersons' success58. The case of identical twins from Germany shows that_________.A. environment can help determine people's body shapeB. genes are the decisive factors for people's body shapeC. identical twins are likely to enjoy different sportsD. identical twins may have different genes for different sports59. Which of the following is NOT mentioned by Craig Sharp as a required quality for asportsperson to win an Olympic gold medal?A. The physical strength.B. The right training conditions.C. The talent for the sports.D. The endurance for pains.60. Seventeen years ago Megan Still was chosen for rowing because____________.A. she had the talent for rowingB. her body shape was right for a rowerC. she had the performance genesD. she was a skillful rower61. The word "elite" in Paragraph 5 means ________ .A. the most wealthyB. the most skilledC. the most industriousD. the most intelligent62. The elite athletes of the future may come from people who naturally possess___________.A. the best body shapes and an iron purposeB. the extremes of the right physique and strong willsC. the right psychological conditions and sports talentsD. the right physique and genes for sportsPassage ThreeFor years, a network of citizens' groups and scientific bodies has been claiming thatscience of global warming is inconclusive. But who funded them?Exxon's involvement is well known. ExxonMobil is the world's most profitablecorporation. It makes most of its money from oil, and has more to lose than any othercompany from efforts to tackle climate change. To safeguard its profits, ExxonMobilneeds to sow doubt about whether serious action needs to be taken on climate change.But there are difficulties: it must confront a scientific consensus as strong as that whichmaintains that smoking causes lung cancer or that HIV causes Aids. So what's itsstrategy?The website , using data found in the company's official documents,lists 124 organizations that have taken money from the company or work closely withthose that have. These organizations take a consistent line on climate change: that thescience is contradictory, the scientists are split, environmentalists are liars or lunatics, andif governments took action to prevent global warming, they would be endangering theglobal economy for no good reason. The findings these organizations dislike are labeled"junk science". The findings they welcome are labeled "sound science".This is not to claim that all the science these groups champion is bogus. On thewhole, they use selection, not invention. They will find one contradictory study - such asthe discovery of tropospheric (对流层的) cooling - and promote it relentlessly. They willcontinue to do so long after it has been disproved by further work. So, for example, JohnChristy, the author of thetroposphere paper, admitted in August 2005 that his figureswere incorrect, yet his initial findings are still being circulated and championed by manyof these groups, as a quick internet search will show you.While they have been most effective in the United States, the impacts of theclimate-change deniers sponsored by Exxon have been felt all over the world. Bydominating the media debate on climate change during seven or eight critical years inwhich urgent international talks should have been taking place, by constantly seedingdoubt about the science just as it should have been most persuasive, they have justifiedthe money their sponsors have spent on them many times over. 63. Which of the following has NOT been done by the organizations to establish theirposition on climate change'?A. Damaging the reputation of environmentalists.B. Emphasizing the lack of consensus among scientists.C. Stressing the unnecessary harm to tile global economy.D. Protecting the scientific discoveries from being misused.64. Which of the following is closest in meaning to "bogus' (in Paragraph 4)?A. Reasonable.B. Fake.C. Limitless.D. Inconsistent.65. John Christy is mentioned to show_______________.A. how closely these organizations work with scientistsB. how these organizations select scientific findings for theirownpurposeC. how important correct data are for scientists to make sound discoveriesD. how one man's mistake may set back the progress of science66. The organizations sponsored by Exxon ___________.A. have lived up to their promisesB. have almost caused worldwide chaosC. have failed to achieve their original goalD. have misunderstood the request of the sponsor67. The passage is mainly focused on____________.A. Exxon's involvement in scientific scandalsB. Exxon's contributions to the issue of climate changeC. Exxon's role in delaying solutions to global warmingD. Exxon's efforts to promote more scientific discoveries68. What is the author's tone in presenting the passage?A. Factual.B. Praiseful.C. Biased.D. Encouraging.Passage FourWhere anyone reaching the age of 60 was considered to be near death's door at theturn of the 20th century, it is barely old enough for retirement at the turn of the 21stcentury. And scientists are still not holding back. They say that as new anti-ageingtreatments become available, our species will get even older. While few would argue thatliving longer is an attractive idea, the rapid increase in the number of years begs aquestion: Can our health expectancy be as close as possible to our life expectancy?Predictions for future health expectancy have changed over the past few decades. Inthe 1980s, life expectancy was increasing but the best data suggested that for everyincreased year of life expectancy, a greater fraction was disabled life expectancy. Whatwe would see was a piling up of chronic illness and related disability which medicalscience couldn't prevent.But that world view changed suddenly in the early 1990s with the publication of astudy by researchers at DukeUniversity, who had been following the health of 20,000people for almost a decade. They showed that disability among the elderly was not onlydropping, but it was doing so at an ever-increasing rate.Arian Richardson, director of the Barshop Institute for Ageing and Longevityresearch, predicts that understanding the mechanisms behind calorie restriction and othergenetic reasons behind ageing could be used within the next two decades to give peopleseveral extra healthy years of life. Restrict how much an animal eats, for example, and itwill live longer. In lab experiments, rats on calorie-restricted diets were found to bephysiologically younger, got diseases later in life and, at any rate, had less severe cases."From the models that have been looked at, the increase in lifespan is usually in the rangeof 15-30% maximum," says Richardson. Cutting calories is thought to trigger a switch inan animal's behaviour from normal to a state of stasis in which growth and ageing aretemporarily put on hold. When food becomes available again, the animal's behaviourswitches back.Richardson says that thinking about stopping ageing is a "little bit silly" at themoment but doesn't dismiss it altogether, arguing that none of the illnesses related toageing should be inevitable. Start with a high-quality body (and that means eating yourgreens, not smoking and doing lots of exercise in your younger days) and you can keep itgoing for longer with high quality maintenance. "It'll be like the difference between aRolls-Royce and a cheap car."69. It can be seen from the first paragraph that people have doubts on whether _____________.A. is possible to live a longer healthyandlifeB. humans can live as long as scientists predictC. living longer is still considered a good ideaD. new anti-ageing treatments are safe for humans70. In the 1980s, the data on people's health expectancy_______________.A. gave an optimistic predictionB. showed an unclear futureC. led to a pessimistic perceptionD. turned out to be a mixed blessing71. In the lab experiment on rats,_____________.A. food restriction is not the only factor proved to have workedB. responses to food restriction vary from animal to animalC. the animals' lifespan increases with the amount of food eatenD.different amounts of food cause a change in the animals' behavior72. Richardson believes that_________.A. it is impossible for humans to stop ageingB. it is worthless to talk about stopping ageingC. stopping ageing is a dream that may come trueD. illness is the biggest obstacle to stopping ageing73. Rolls-Royce is used to convey the idea that_______________.A. quality life is out of reach for most peopleB. quality life can slow down the process of agingC. how long one can live depends on the genes one carriesD. the more money one invests in health, the healthier one will be.74. The most suitable title for the passage is“___________”.A. Problems of An Ageing SocietyB. Health Care for the ElderlyC. Eating Healthier, Living LongerD.The Future of Old AgePassage FiveIn dealing with a student who is acting aggressively toward his classmates, you wantto send a strong message that aggressive behavior will not be tolerated in your classroom.In addition, you want to help him develop more appropriate ways of settling disputes withhis peers.If two elementary school students are engaged in a fight, use a strong loud voice tostop it. If that doesn't work, you might say something odd ("Look up! The ceiling isfalling!") to divert their attention. If they still don't stop and you can't separate them,send a student to the office to get help. If a crowd of children is gathering, insist that theymove away or sit down, perhaps clapping your hands to get their attention: After theincident is over, meet with the combatants together so they can give you their versions ofwhat happened and you can help them resolve any lingering problems. Also notify theparents.Speak in a firm, no-nonsense manner to stop a student's aggressive behavior: usephysical restraint as a last resort. When responding to the student, pay attention to yourverbal as well as non-verbal language. Even if he is yelling at you, stay calm. Allow himto express what he is upset about without interrupting him and then acknowledge hisfeelings. Avoid crossing your arms, pointing a finger or making threats: any of thoseactions could intensify his anger and stiffen his resistance.You might conclude that a student's aggressive behavior warrants separating himfrom the rest of the class, either to send him a strong message that what he did merits aserious consequence or to protect the other students. You can do that by giving him a timeout in class or by sending him to the office.Although he might expect you to react punitively, surprise him by reactingsupportively. Express your confidence that he can resolve problems without being hurtfulto his peers. Tell him that you think he must be upset about something to lose control ashe did and you want to understand what might be bothering him. If he does open up toyou, listen attentively without interrupting. Speaking m a calm voice, tell him that youunderstand why he was upset, but stress that he has to find a way to express his angerwith words rather than with his hands.You don't want to force an aggressive student to say he is sorry because that mightfuel his anger, however, you do want to strongly encourage him to make amends with thestudent he hit. If he is willing to do that, it will help soothe hurt feelings and avoid futureconflicts.75. What is the purpose of saying something odd when seeing students in a fight?A. To please the students.B. To surprise the students.C. To get the students' attention.D. To distract the students' attention.76. What is to be done about a student's aggressive behavior?A. Respond calmly but finny.B. Tell the student's parents immediately.C. Ask other students for help to stop the action.D. Have the student go to see the principal.77. What is NOT encouraged to do toward an aggressive student?A. Use physical restraint.B. Give the student a time out.C. Point at the student or make threats.D. Talk with the student privately.78. What does the word "'punitively" (in Paragraph 5) probably mean?A. Surprisingly.B. Depressingly.C. Involving persuasion.D. Involving punishment.79. What might be the last step to help all aggressive student?A. Encourage the student to be nice to the student he hit.B. Ask the student to promise he'll never do it again.C. Force the student to apologize for his behavior.D. Persuade the student to open up to you.80. Which of the following is the best title of the passage?A. Problems in Classrooms.B. Dealing with Student Aggression.C. Aggressive Behavior in Classrooms.D. Settling a Student Fight.PART V TRANSLATION (30 minutes, 20 points)Section A (15 minutes, 10 points)One of the unintended consequences of the flattening world is that it puts differentsocieties and cultures in much greater direct contact with one another. It connects peopleto people much faster than people and cultures can often prepare themselves. Somecultures thrive on the sudden opportunities for collaboration that this global intimacymakes possible. Others are frustrated, and even humiliated by this close contact, which,among other things, makes it easy for people to see where they stand in the world inrelation to everyone else. All of this helps to account for the emergence of one of themost devastating forces today - the suicide bombers and other terrorist organizationswhich have no regard for human lives and which it is in our best interest to wipe out.

For the first time in 30 years, Harvard is 41 its under-graduate curriculum. William Kirby, dean of the faculty of arts and sciences, said this 42 what many people had said that Harvard's curriculum did not provide enough choice and encourage premature specialization."Harvard needs to 43 its education for a world where global connections, cross disciplinary research, and science in general are ever more important," said Kirby.Particularly 44 is the idea that students need to spend time overseas, either in a traditional study-abroad program or over a summer, perhaps doing an internship or research.Students can either find the program themselves or 45 some exchange programs offered by the university." 46 studying Chinese history without leaving the university, students interested in the subject should be spending a semester at a university in China."It was also recommended that Harvard 47 its required "core curriculum". The core curriculum was an effort created in 1978 to broaden education by requiring students to choose from a list of courses in several areas of study. Classes often focused on a highly 48 topic and emphasized "ways of knowing".Under a new plan, the curriculum would be replaced with a set of 49 "Harvard College Courses", emphasizing knowledge over methodology and 50 wider territory. A life sciences course, for example, might combine molecular and evolutionary biology and psychology, rather than focusing on one of those, said Benedict Gross, HarvardCollege dean.41.

It suggests that it could be as damaging to our health as exposure to the radiation from the 1986 Ukraine nuclear power disaster. The report was published by the UK Royal Commission on Environmental Pollution. But what can city people do to reduce exposure to air pollution.'? Quite a lot, it turns out.Avoid walking in busy streets. Choose side streets and parks instead. Pollution levels can fall a considerable amount just by moving a few meters away from the main pollution source--exhaust fumes(烟气). Also don't walk behind smokers. Walk on the windward side of the street where exposure to pollutants can be 50 percent less than on the downwind side.Sitting on the driver's side of a bus can increase your exposure by 10 percent, compared with sitting on the side nearest the pavement. Sitting upstairs on a double-decker can reduce exposure. It is difficult to say whether traveling on an underground train is better or worse than taking the bus. Air pollution on underground trains tends to be, less toxic than that at street level, because underground pollution is mostly made up of tiny iron particles thrown up by wheels hitting the rails. But diesel and petrol fumes have a mixture of pollutants.When you are crossing a road, stand well back from the curb while you wait for the light to change. Every meter really does count when you are close to traffic. As the traffic begins to move, fumes can be reduced in just a few seconds. So holding your breath for just a moment can make a difference, even though it might sound silly.There are large sudden pollution increases during rush hours. Pollution levels fall during nighttime. The time of year also makes a big difference. Pollution levels tend to be at their lowest during spring and autumn when winds are freshest. Extreme cold or hot weather has a trapping effect and tends to cause a build-up of pollutants.51. What is the passage mainly about?A. How to fight air pollution in big cities.B. How to avoid air pollution in big cities.C. How to breathe fresh air in big cities.D. How serious air pollution is in big cities.52. According to the report, air pollution in big cities __________.A. can be more serious than Chernobyl nuclear disasterB. cannot be compared with the disaster in ChernobylC. can release as damaging radiation as the Chernobyl disasterD. can be more serious than we used to think53. When you walk in a busy street, you should walk on the side ___________.A. where the wind is comingB. where the wind is goingC. where the wind is weakerD. where the wind is stronger54. If you take a bus in a big city in China, you should sit _________.A. on the left side in the busB. on the right side in the busC. in the middle of the busD. at the back of the bus55. It is implied in the passage that ________.A. people should not take street level transportationB. tiny iron particles will not cause health problemsC. air pollution on an underground train is less poisonousD. traveling on an underground train is better than taking the bus56. While waiting to cross a busy street, you should ___________.A. wait a few seconds until the fumes reduceB. stay away from the traffic as far as possibleC. hold your breath until you get to the other side of the streetD. count down for the light to changePassage TwoGlobal warming poses a threat to the earth, but humans can probably ease the climate threats brought on by rising levels of carbon dioxide in the atmosphere, global climate specialist Richard Alley told an audience at the University of Vermont. Alley said his research in Greenland suggested that subtle changes in atmospheric patterns leave parts of the globe susceptible to abrupt and dramatic climate shifts that can last decades or centuries.Almost all scientists agree that increasing levels of carbon dioxide in the atmosphere created as humans burn fossil fuel is warming the planet. How to respond to the warming is a matter of intense political, scientific and economic debate worldwide.Alley said he was upbeat about global warming because enough clever people existed in the world to find other reliable energy sources besides fossil fuels. He said people can get rich finding marketable alternatives to fossil fuel. "Wouldn't it be useful if the United States were to have a piece of the action. Wouldn't it be useful if some bright students from University of Vermont were to have a piece of the action," Alley said.Alley said that Europe and parts of eastern North America could in a matter of a few years revert to a cold, windy region, like the weather in Siberia. Such shifts have occurred frequently over the millennia, Alley's research shows. A gradual change in atmospheric temperature, such as global warming, could push the climate to a threshold where such a shift suddenly occurs, he said.Alley told his audience of about 200 people in a University of Vermont lecture hall Wednesday evening that he couldn't predict if, when or where sudden shifts toward cold, heat, drought or water could occur under global warming, but it is something everyone should consider."This is not the biggest problem in the world. The biggest problem in the world is getting along with each other. But it's part of that because we're not going to get along with each other if we're not getting along with the planet," Alley said.57. According to Ally the climate threats to the earth brought by global warming _________.A. can be easedB. can be endedC. will become worseD. will last for decades58. Ally's research shows that dramatic climate changes may be caused by ___________.A. abrupt changes in atmospheric patternsB. subtle changes in atmospheric patternsC. humans' burning of fossil fuelD. increasing levels of carbon dioxide59. The word "upbeat" (in Paragraph 3) probably means __________.A. pessimisticB. optimisticC. worriedD. insensible60. What does Ally suggest people do in order to reduce global warming?A. To find other energy sources besides fossil fuels.B. To start a political, scientific and economic debate.C. To take action to burn no fossil fuels.D. To call on people worldwide to protect our earth.61. Alley predicts that global warming could turn Europe and parts of eastern North America into ______.A. a region like SiberiaB. a warmer and warmer placeC. a tropical regionD. a place like North Pole62. Ally thinks the biggest problem in the world isA. lack of harmonyB. violenceC. global warmingD. climate shiftPassage ThreeWe're talking about money here, and the things you buy with it--and about what attitude we should take to spending.Across most of history and in most cultures, there has been a general agreement that we should work hard, save for the future and spend no more than we can afford. It's nice to have a comfortable life right now, but it is best to think of the future. Yet economists have long known that things don't work out that way. They point to an idea called the "paradox of thrift." Imagine you are the owner of a big business making consumer goods. You want your own staff to work hard and save their money. That way, you don't have to pay them as much. But you want everybody else to spend all the money they can. That way you make bigger profits.It's a problem on a global scale. Many people in the UK and the United States are worried about levels of personal debt. Yet if people suddenly stopped buying things and started paying back what they owe to credit card companies, all the economies of the Western world would collapse. The banks would be happy, but everybody else would be in trouble.Traditionally, economists have believed that spending money is about making rational choices. People buy things to make their life better in some way. But in recent years, they have noticed that people often do not actually behave in that way. We all know people who take pleasure in buying useless things. And there are many people around who won't buy things that they need.In a recent series of experiments, scientists at StanfordUniversity in the US confirmed something that many people have long suspected. People spend money because the act of buying gives them pleasure. And they refuse to spend when it causes them pain. The scientists discovered that different areas of the brain that anticipate pleasure and pain become more active when we are making a decision to buy things. People who spend a lot have their pleasure centers stimulated. People who like to save find buying things painful.If you think you really want that product because it's beautiful or useful, you are wrong, say the scientists. The desire to buy something is a product of the reaction between chemicals released by different parts of the brain when the eyes see a product.63. Across most of history and in most cultures, people are advised to _____________.A. enjoy their present life as much as possibleB. spend every penny they have earnedC. save every penny for the futureD. save some money for later use64. According to the context, "paradox" (in Paragraph 2) probably means “__________”.A. contradictionB. hypothesisC. declarationD. assertion65. It is implied that many people in the UK and the United StatesA. have to work hard to make ends meetB. spend more than they can affordC. have trouble in paying back their debtsD. don't pay back their debts on time66. According to the resent studies made by economists, people__________.A. take pleasure in buying useless thingsB. won't buy things that they need.C. spend their money irrationallyD. make rational choices while spending their money67. It has been proved by the scientists at StanfordUniversity that some people like to save money because_____.A. they like keeping their money in the bankB. they will feel safe if they save enough money for the futureC. they don't want to spend their money on useless thingsD. spending money gives them pain68. The passage mainly tells us_________.A. how to spend our moneyB. it is better to save some money for the futureC. it is the chemicals released from the brain that decide our spendingD. how to form a habit of rational spendingPassage FourTrees are good. Good enough to hug. Planting trees will make the world cooler than it would otherwise be. This is the subject of a newly published study by GovindasamyBala, of the Lawrence Livermore National Laboratory, in California, and his colleagues. DrBala has found, rather counter-intuitively, that removing all of the world's trees might actually cool the planet down.The reason for this is that trees affect the world's temperature by means other than the carbon they take in. For instance forests remain quite a dark shade even after a snowstorm. They are certainly darker than grasslands, and thus they can absorb more of the sun's heat than vegetation which might otherwise cover the same stretch of land. That warms things up.DrBala and his colleagues took such effects into account using a computer model called the Integrated Climate and Carbon Model. Unlike most climate-change models, which calculate how the Earth should absorb and radiate heat in response to a list of greenhouse-gas concentrations, this one has many subsections that represent how the carbon cycle works, and how it influences the climate.Overall, DrBala's model suggests that complete deforestation would cause an additional 1.3 C temperature rise compared with business as usual, because of the higher carbon-dioxide levels that would result. However, the additional reflectivity of the planet would cause 1.6 C of cooling. A treeless world would thus be 0.3 C cooler than otherwise.No one, of course, would consider chopping down the world's forests to keep the planet cool. But having made their point, DrBala and his colleagues then went on to look at forest growth and loss at different latitudes. Planting trees in convenient places such as Europe and North America may actually be counterproductive. In Russia and Canada, cutting trees down led mostly to localcooling. The carbon dioxide this released into the atmosphere, though, warmed the world all over. Around the equator, by contrast, warming acted locally (as well as globally), so a tropical country would experience warming created by cutting down trees.The results follow increasing criticism from climate scientists of the benefits of forestry schemes to offset carbon emissions. Planting trees to neutralise carbon emissions has become a big business: £60m worth of trees have been bought this year, up from £20m in 2005. By 2010 the market is expected to reach £300m.69. According to the passage, trees make the world warmer because of their _________.A. deep colorB. round shapeC. enormous sizeD. high reflectivity70. DrBala's Integrated Climate and Carbon Model____________.A. supports the findings of other climate modelsB. is based on the results of other climate modelsC. uses a system different from other climate modelsD. challenges the basic theory of other climate models71. Based on DrBala's model, a treeless world would__________.A. cause serious environmental problemsB. prove helpful in fighting global warmingC. make it difficult to deal with climate changeD. raise carbon dioxide levels and global temperature72. According to DrBala, the best places to plant trees would be__________.A. North AmericaB. EuropeC. High-latitude countries.D. tropical countries73. As is shown in the passage, criticism from other climate scientists__________.A. should be taken rather seriouslyB. is unreasonable and far-fetchedC. involves mostly economic interestsD. is voiced on behalf of the government74. The best title for the passage is____________.A. Should Green Trees Be Left Alone?B. Why Green Trees Might Not Be Green?C. How to Help Green Trees Survive?D. How to Go Green with Green Trees? Passage FiveThe patient needed a spinal tap, and a senior attending physician asked a medical resident whether a preparatory blood test had been checked. The medical student was stunned to hear him answer in the affirmative, because she was quite certain it had not been checked.Well, almost certain.Doctors in training sometimes confront situations in which they worry that their supervising physicians are making mistakes or bending the truth. Yet even though such acts can jeopardize patients, the inclination and ability of young doctors to speak up is hampered by the hierarchies in teaching hospitals.On the top were the senior physicians who made rounds on the wards once or twice daily. Next were the overworked residents, who essentially lived in the hospital while training. Last were the medical students who were most assuredly at the bottom of the heap.The student whose resident seemingly lied to the attending physician about the blood test did not speak up. The resident was a good doctor, she said, and so she had given him the benefit of the doubt. And, she added, both the resident and the attending physician would be grading her.What should a medical student do in such a situation? One possibility is to take the matter up with a more senior doctor. Or the student might go directly to the patient or family, telling them that the physicians have a genuine disagreement and that they deserve to know about it.These options seem logical on paper. As the ethicist James Dwyer has written in The Hastings Center Report, "The practice of always keeping quiet is a failure of caring." But in the real world, it may be extremely difficult to go up the chain of command.Fortunately, medical educators are increasingly recognizing the dilemmas that doctors in training confront when they witness behavior that makes them uncomfortable. Students and residents are now expected to provide routine feedback -- positive and negative -- about their supervising physicians at the close of their rotation.Of course, physicians and students need to be educated about how to give feedback in professional and nonconfrontational ways.

Software is a program that contains the step-by-step instructions that tell the computer how to do its work. Hardware consists of the physical equipment that processes the data to create information. Data consists of raw unprocessed facts, including text, numbers, images, and sounds.Difficulty: Medium67. (p. 6) Where would it be most relevant to use the term "data" and the term "information"? Give an example of each.Data are unprocessed facts, including text, numbers, images and sound. An example might be a listing of all customer purchases at a bookstore over the last year. Information is processed data that has been rendered usable with the help of various types of software. From the previous example, you could derive information such as the addresses of customers who bought more than $500 worth of books or the year's top ten horror novels.Difficulty: Medium68.
