1、6月21日大學(xué)英語(yǔ)六級(jí)真題預(yù)測(cè)及答案What will the world be like in fifty years?This week some top scientists, including Nobel Prize winners, gave their vision of how the world will look in 2056,fron gas-powered cars to extraordinary health advances, John Ingham reports on what the worlds finest minds believe our futu

2、res will be.For those of us lucky enough to live that long,2056 will be a world of almost perpetual youth, where obesity is a remote memory and robots become our companions.We will be rubbing shoulders with aliens and colonizing outer space. Better still, our descendants might at last live in a worl

3、d at peace with itself.The prediction is that we will have found a source of inexbaustible, safe, green energy, and that science will have killed off religion. If they are right we will have removed two of the main causes of war-our dependence on oil and religious prejudice.Will we really, as todays

4、 scientists claim, be able to live for ever or at least cheat the ageing process so that the average person lives to 150?Of course, all these predictions come with a scientific health warning. Harvard professor Steven Pinker says: “This is an invitation to look foolish, as with the predictions of do

5、med cities and nuclear-powered vacuum cleaners that were made 50 year ago.”Living longerAnthony Atala, director of the Wake Forest Institute in North Carolina, belives failing organs will be repaired by injecting cells into the body. They will naturally to straight to the injury and help heal it. A

6、system of injections without needles could also slow the ageing process by using the same process to “tune” cells.Bruce Lahn, professor of human genetics at the University of Chicago, anticipates the ability to produce“unlimited supplies” of transplantable human organs without the needed a new organ

7、, such as kidney, the surgeon would contact a commercial organ producer, give him the patients immuno-logical profile and would then be sent a kidney with the correct tissue type.These organs would be entirely composed of human cells, grown by introducing them into animal hosts, and alloweing them t

8、o deveoop into and organ in place of the animals own. But Prof. Lahn believes that farmed brains would be “off limits”.He says: “Very few people would want to have their brains replaced by someone elses and we probably dont want to put a human brain ing an animal body.”Richard Miller, a professor at

9、 the University of Michigan, thinks scientist could develop“an thentic anti-ageing drugs” by working out how cells in larger animals such as whales and human resist many forms of injuries. He says:“Its is now routine, in laboratory mammals, to extend lifespan by about 40%. Turning on the same protec

11、evolve on Mars well as Earth.”Within 50years he hopes scientists will prove that alien life came here in Martian meteorites(隕石).Chris McKay,a planetary scientist at NASAs Ames Research Center.believes that in 50 years we may find evidence of alien life in ancient permanent forst of Mars or on other

12、planers.He adds:”There is even a chance we will find alien life forms here on Earth.It mightbe as different as English is to Chinese.Priceton professor Freeman Dyson thinks it “l(fā)ikely” that life form outer space will be discovered defore 2056 because the tools for finding it, such as optical and rad

13、io detection and data processing,are improving.He ays:”As soon as the first evidence is found,we will know what to look for and additional discoveries are likely to follow quickly.Such discoveries are likely to have revolutionary consequences for biology, astronomy and philosophy. They may change th

16、opher Reeve.She says:”I believe that the day is not far off when we will be able to profescribe drugs that cause severes(斷裂旳) spinal cords to heal,hearts to regenerate and lost limbs to regrow.“People will come to expect that injured or diseased organs are meant to be repaired from within,inmuch the

17、 same way that we fix an appliance or automobile:by replancing the damaged part with a manufacturer-certified new part.”She predict that within 5 to 10 years fingers and toes will be regrown and limbs will start to be regrown a few years later. Reparies to the nervous system will start with optic ne

31、ion. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line thought the centre.Passage OneImagine waking up and

32、finding the value of your assets has been halved. No, youre not an investor in one of those hedge funds that failed completely. With the dollar slumping to a 26-year low against the pound, already-expensive London has become quite unaffordable. A coffee at Starbucks, just as unavoidable in England a

33、s it is in the United States, runs about $8.The once all-powerful dollar isnt doing a Titanic against just the pound. It is sitting at a record low against the euro and at a 30-year low against the Canadian dollar. Even the Argentine peso and Brazilian real are thriving against the dollar.The weak d

34、ollar is a source of humiliation, for a nations self-esteem rests in part on the strength of its currency. Its also a potential economic problem, since a declining dollar makes imported food more expensive and exerts upward pressure on interest rates. And yet there are substantial sectors of the vas

35、t U.S. economy-from giant companies like Coca-Cola to mom-and-pop restaurant operators in Miami-for which the weak dollar is most excellent news.Many Europeans may view the U.S. as an arrogant superpower that has become hostile to foreigners. But nothing makes people think more warmly of the U.S. th

36、an a weak dollar. Through April, the total number of visitors from abroad was up 6.8 percent from last year. Should the trend continue, the number of tourists this year will finally top the peak? Many Europeans now apparently view the U.S. the way many Americans view Mexico-as a cheap place to vacat

37、ion, shop and party, all while ignoring the fact that the poorer locals cant afford to join the merrymaking. The money tourists spend helps decrease our chronic trade deficit. So do exports, which thanks in part to the weak dollar, soared 11 percent between May and May . For first five months of , t

38、he trade deficit actually fell 7 percent from .If you own shares in large American corporations, youre a winner in the weak-dollar gamble. Last week Coca-Colas stick bubbled to a five-year high after it reported a fantastic quarter. Foreign sales accounted for 65 percent of Cokes beverage business.

39、Other American companies profiting from this trend include McDonalds and IBM.American tourists, however, shouldnt expect any relief soon. The dollar lost strength the way many marriages break up- slowly, and then all at once. And currencies dont turn on a dime. So if you want to avoid the pain infli

40、cted by the increasingly pathetic dollar, cancel that summer vacation to England and look to New England. There, the dollar is still treated with a little respect. 52.

44、 not increase in the short term.B.The value of a dollar will not be reduced to a dimeC.The dollars value will drop, but within a small margin.D.Few Americans will change dollars into other currencies.Passage Two In the college-admissions wars, we parents are the true fights. We are pushing our kids

45、to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. Ive twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids college background as e prize demonstrating how well weve raised the

46、m. But we cant acknowledge that our obsession(癡迷) is more about us than them. So weve contrived various justifications that turn out to be half-truths, prejudices or myths. It actually doesnt matter much whether Aaron and Nicole go to Stanford. We have a full-blown prestige panic; we worry that ther

47、e wont be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. Underlying the hysteria(歇斯底里) is the belief that scarce elite degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better

48、contacts. All that is plausibleand mostly wrong. We havent found any convincing evidence that selectivity or prestige matters. Selective schools dont systematically employ better instructional approaches than less selective schools. On two measuresprofessors feedback and the number of essay examssel

49、ective schools do slightly worse. By some studies, selective schools do enhance their graduates lifetime earnings. The gain is reckoned at 2-4% for every 100-poinnt increase in a schools average SAT scores. But even this advantage is probably a statistical fluke(偶爾). A well-known study examined stud

50、ents who got into highly selective schools and then went elsewhere. They earned just as much as graduates from higher-status schools.Kids count more than their colleges.Getting into yale may signify intellgence,talent andAmbition. But its not the only indicator and,paradoxically,its significance is

51、declining.The reason:so many similar people go elsewhere.Getting into college is not life only competiton.Old-boy networks are breaking down.princeton economist Alan Krueger studied admissions to one top Ph.D.program.High scores on the GRE helpd explain who got in;degrees of prestigious universities

52、 didnt.So,parents,lighten up.the stakes have been vastly exaggerated.up to a point,we can rationalize our pushiness.America is a competitive society;our kids need to adjust to that.but too much pushiness can be destructive.the very ambition we impose on our children may get some into Harvard but may

53、 also set them up for disappointment.one study found that,other things being equal,graduates of highly selective schools experienced more job dissatisfaction.They may have been so conditioned to deing on top that anything less disappoints.57.Why dose the author say that parengs are the true fighters

54、 in the college-admissions wars? A.They have the final say in which university their children are to attend. B.They know best which universities are most suitable for their children. C.they have to carry out intensive surveys of colleges before children make an application. D.they care more about wh
