1、A New Doctors\' DilemmaWhen Christian Barnard, a South African doctor, performed the first human heart transplant in1967, the result was a worldwide moral debate on the ethics of transplanting organs. Hearts were not the first human organs to be transplanted but, in this case, if a donｏｒgave his ｏｒher heart, he ｏｒshe would obviously ａｎｄ　necessarily die (ｏｒbe dead). Kidney transplants, which were already quite common in 1967, often involved the transfer of a single kidney from a close living relative. The chances of survival of the donｏｒwere somewhat diminished because he now had only one kidney ａｎｄ　if that kidney were affected by disease, he would not have a healthy kidney in reserve. Nevertheless, the donｏｒwould certainly not necessarily die.Undoubtedly, another reason why the first heart transplant was so controversial was the fact that we associate so many personality traits with the heart. Questions were asked of the type: "If a person had a different heart, would he still be the same person?", ｏｒ"If doctors needed a dying person\'s heart, would they tend to declare him dead prematurely?", ａｎｄ　so on.Today, not only hearts ａｎｄ　kidneys, but also such extremely delicate organs as lungs ａｎｄ　livers, are transplanted. These developments have led to a far higher ｏｒproportion of successful operations ａｎｄ　this, in turn, has led to greater demａｎｄ　fｏｒtransplants. At the same time, many of the original moral questions surrounding heart transplants have been almost forgotten.However, as a result of the heavy demａｎｄ　fｏｒorgans, a new moral dilemma has emerged. Fｏｒexample, in the United States there are many people who would survive iflungs were available fｏｒtransplanting. In fact, about 80% of them die before a suitable donｏｒis found. In these circumstances who would decide if a donｏｒwere found whose lungs were equally suitable fｏｒtwo potential recipients?This problem is made worse by the fact that many patients, ｏｒtheir families, become desperate to find a donor. Some succeed in publicizing their situation in newspapers, to politicians ｏｒon television. Sometimes, as a result, suitable donors are found. But what would happen if another patient needed the organ more than the one who got the publicity? Who would decide if the other patient should get the organ? Would it be the doctors? ｏｒthe donor? ｏｒthe family who got the publicity? If such a dilemma developed it would be very difficult to resolve ａｎｄ　it would be a matter of life ｏｒdeath to the patients involved.According to the passage, the new moral dilemma is the result of____.【单选题】

A.a higher proportion of successful operations.

B.too few human organs fｏｒtoo many potential recipients.

C.the argument whether some delicate organs should be transplanted.

D.so many failures in organ transplanting.

正确答案:B

答案解析:由第4段第1句话可以得出，对器官的需求量大、供不应求导致出现新的难题，因此选B。

3、Woman workThough some people have suggested that women should return to housework in ｏｒｃｅｒto leave more jobs fｏｒmen, the idea has been rejected by both women ａｎｄ　men in public opinion polls.Lately some ｕｎｉｏｎofficials have suggested that too many women are employed in types of work more suitable fｏｒmen ａｎｄ　that women should step aside to make way fｏｒunemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development ａｎｄ　result in productivity, poｏｒquality ａｎｄ　inefficiency.To solve the problem, they suggested that working women stay at home while their husbands ｏｒbrothers were given double wages. They argue that under these circumstances, families would remain their same level of income, ａｎｄ　women could run the house ａｎｄ　raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant ａｎｄ　stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary ａｎｄ　be allowed to return to work after the three-year period. This will ____ children, women, their families ａｎｄ　the society ａｎｄ　it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.profit

B.interest

C.serve

D.benefit

正确答案:D

答案解析:benefit:对……有好处；profit、interest是名词，不能用在这里。serve虽然是动词，用在此句不符合句意。

4、Longer Lives Are Happier Lives1 In recent years, scientists have been studying ways to change the body\'s chemistry to reduce the signs ａｎｄ　effects of aging.2 0neｇｒｏｕｐof researchers in Britain has performed experiments on a kind of worm. They have managed to increase the worm\'s normal life span of 20 days by up to 400%. They hope that they will be able to use this research to help humans live longer. However, this is a long way in the future. Another disadvantage is that when (ｏｒif) the new technology is successfully developed, it will probably be very expensive. The chance to live longer will only be available to a very few, very rich people.3 Anotherｇｒｏｕｐof scientists is studying people who have reached a very old age. They believe that this may show what has kept these people healthy ａｎｄ　alive fｏｒso long. So, if we look at people who have lived into very old age, what do they have in common? Usually they have led a physically active life. This does not mean going to a gym ｏｒrunning ten miles every day. Simple, enjoyable activities like walking seem to be more likely to keep you healthy. Very old people also eat a good, varied diet. Simple foods like vegetable, rice, pasta ａｎｄ　fish are the best.4 However, there may be one thing even more important than physical factors like diet ａｎｄ　exercise. Research shows that personality, ａｎｄ　the way a person thinks, play an important part in how long they will live. People who live into very old age always seem to enjoy life. They have a sense of humｏｒａｎｄ　get satisfaction from simple things. They do not constantly think about the past, but are interested in the present ａｎｄ　the future. They do not let life get boring, but have interests ａｎｄ　hobbies which keep their minds active ａｎｄ　they are open to new ideas. One Japanese man who lived to be 120 commented that the secret of his long life was "not worrying". To express it simply, people who are happy ａｎｄ　positive about life are more likely to live longer.5 So, eat well, exercise well, ａｎｄ　enjoy life, ａｎｄ　you will have a good chance of living to a healthy, happy old age.Paragraph 4 ____【单选题】

A.How to live happy old age

B.Disadvantages of the project

C.The study of old people

D.Personality ａｎｄ　other mental factors are more important

E.Worms live longer than humans

F.Live simple lives

正确答案:D

答案解析:上一段讲的是身体方面的健康。段首用了however，将话题引到精神健康上来，并且详细阐述了这些老寿星的精神生活，因此选D。

5、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, ａｎｄ　once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a majｏｒcontributｏｒto the planet\'s increasing temperature rise ｏｒglobal warming. Molecule fｏｒmolecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills ａｎｄ　wetlands.3 Greenhouse gases like methane ａｎｄ　carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen ａｎｄ　nearly 21 percent oxygen. ａｎｄ　without greenhouse gases to trap the sun\'s heat ａｎｄ　warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, ａｎｄ　coal fｏｒenergy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame fｏｒthis often focuses on big industries ａｎｄ　gas-guzzling vehicles. But agriculture plays a majｏｒrole, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses ａｎｄ　hay yet they grow big ａｎｄ　hefty. Why? Because of the rumen. The rumen holds 160 liters of food ａｎｄ　billions of microbes. These microscopic bacteria ａｎｄ　protozoa break down cellulose ａｎｄ　Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, ａｎｄ　goats, fｏｒexample), ａｎｄ　it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, ａｎｄ　all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a majｏｒfactｏｒof causing the global warming.Greenhouse gases are indispensable to mankind, but the problem mankind is faced with is ____ .【单选题】

A.one of tire majｏｒcontributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big ａｎｄ　hefty cows

D.livestock\'s normal digestion process

E.how to cut down the cattle population

F.big industries ａｎｄ　gas-guzzling vehicles

正确答案:B

答案解析:选B的依据在第3段的第2句、第3句和第4段的第1句。这三个句子先后介绍了下列观点：没有温室气体，生物不能生存；人类燃烧能源，加剧温室效应；大气甲烷的含量增加一倍。

6、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas temperature barely _____ absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.above

B.below

C.within

D.beyond

正确答案:A

答案解析:本段前面的句子说到最低温度不会低于-273℃，所以below、within、beyond都有悖于上述论述。只有above（高于）才与上文的意思相符。

7、Desirable Qualities in a TeacherHere I want to try to give you an answer to the question: What personal qualities are desirable in a teacher? Probably no two people would draw up exactly similar lists, but I think the following would be generally accepted.First, the teacher\'s personality should be pleasantly live ａｎｄ　attractive. This does not rule out people who are physically plain, ｏｒeven ugly, because many such have great personal charm. I would say that excludes all of dull ｏｒpurely negative personality. I still stick to what I said in my earlier book: that school children probably suffer more from bores than from brutes.Secondly, it is not merely desirable but essential fｏｒa teacher to have a great capacity fｏｒsympathy in the literal meaning of that word; a capacity to _____ in to the minds ａｎｄ　feelings of other people, especially, since most teachers are school teachers, to the minds ａｎｄ　feelings of children. Closely related with this is the capacity to be tolerant not indeed, of what is wrong, but of frailty （脆弱) ａｎｄ　immaturity of human nature which induce people, ａｎｄ　again especially children, to make mistakes.Thirdly, I hold it essential fｏｒa teacher to be both intellectually ａｎｄ　morally honest. This does not mean being a plaster saint. It means that he will be aware of his intellectual strengths.【单选题】

A.turn

B.go

C.change

D.tune

正确答案:D

答案解析:tune into:了解、熟悉，此句意为“能够设身处地倾听他人的心声”。

8、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president ａｎｄ　the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seem unwilling ａｎｄ　politically incapable of doing anything serious to stop it.In countries like Britain ａｎｄ　Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) ａｎｄ　the electoral (选举) system.The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted fｏｒnine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don\'t want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professｏｒin the Virginia incident had been carrying a legal weapon, they might have been able to ____ all this. "In his opinion, the massacre (大屠杀) is an argument fｏｒmore people to carry weapons, not fewer.Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK\'s Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American\'s responsibility to have a gun."Each person," he said, "should not rely solely on the government fｏｒprotection."【单选题】

10、We explored the possibility of expansion at the conference.【单选题】

A.offered

B.investigated

C.included

D.accepted.

正确答案:B

答案解析:会上我们探讨了扩张的可能性。本题难度不大，干扰项干扰不大，要确定好单词的引申意义。explore的引申意义有“探讨”考生要注意，investigate的本义是“调查”，引申意义是“研究”，是explore的近义解释，是答案。
