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.Why was the first heart transplant controversial?【单选题】

A.Because it was not so successful as people had thought.

B.Because some people argued it was not moral to do so.

C.Because the recipient died on the operation table.

D.Because it was the most difficult operation ever known.

正确答案:B

答案解析:由第1段可知，全球范围的moral debate是因为捐者一定会死的。这不同于肾脏移植，因此违背道德。

2、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach ｏｒany other vegetable ｏｒfruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet ａｎｄ　disease. Since 1957 a team of American researchers has monitored the dietary habits ａｎｄ　medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns ａｎｄ　cancer. Other studies of animals ａｎｄ　humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential fｏｒthe growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver ａｎｄ　dairy products like milk, cheese, butter ａｎｄ　eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables ａｎｄ　fruits, including carrots, spinach, squash, tomatoes, sweet potatoes ａｎｄ　apples.In the Western Electric study, Shekelle ａｎｄ　his colleagues found little correlation between the incidence of lung cancer ａｎｄ　the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in aｇｒｏｕｐof the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even fｏｒlongtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer ａｎｄ　carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. Fｏｒa smoker, a half-cup of carrots every day might possibly make the difference between life ａｎｄ　death.Where is carotene present?【单选题】

A.tomatoes

B.carrots

C.squash

D.all of the above

正确答案:D

答案解析:根据第3段，“维生素A在体内的产生源于胡萝卜素，胡萝卜素在蔬菜、水果中大量存在，包括胡萝卜、菠菜、西葫芦、西红柿和苹果”。因此答案是D。

3、Shopping at Second - hａｎｄ　Clothing StoresWhen 33 years old Pete Barth was in college, shopping at second - hａｎｄ　clothing stores was just something he did－"like changing the tires on his car." He looked at his budget ａｎｄ　decided he could save a lot of money by shopping fｏｒclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) ａｎｄ　wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons fｏｒshopping fｏｒsecond - hａｎｄ　clothing. Some people, like him, shop to save money. Some shop fｏｒa crazy - looking shirt. ａｎｄ　some shop as a means of conserving energy ａｎｄ　helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, fｏｒher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said: "Also, why pay 30 dollars fｏｒa new coat when you can get another one fｏｒa lot less?"Akins said that the SA has shops all over the US－"some as big as department stores". All of the clothes are donated (捐赠), ａｎｄ　when they have a surplus (盈余), they\'ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes fｏｒonly 5 ｏｒ10 dollars.Julia Stocum, 22, points out, however, that the huge amount of second - hａｎｄ　clothing in the US is the result of American wastefulness."I\'d say that second - hａｎｄ　stores are the result of our wasteful, materialistic culture," said Slocum, who works fｏｒa pro - conservation organization, the center of a New American Dream. "Thrift shops prevent waste from going to landfills (垃圾填埋场), They give clothing a second life ａｎｄ　provide cheaper clothing fｏｒthose who can\'t afford to buy new ones ａｎｄ　generate (创造) income fｏｒcharities. They also provide a way fｏｒthe wealthy ａｎｄ　middle classes to shed (摆脱) the guilt fｏｒtheir level of consumption."The word "thrift" in paragraph 1 could be best replaced by【单选题】

A.charity.

B.one dollar.

C.first class.

D.two dollars.

正确答案:A

答案解析:本题有一定难度，需要认真阅读文章，答案依据主要在文章第六段。本题不能靠查词典查单词意思来确定答案。第六段谈到旧货店的所有衣服均为捐赠所得，最后一段有谈到了旧货店所得的收入都捐赠给慈善机构，所以答案是A。

4、Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 ａｎｄ　respond quickly to space station emergencies.The space agency released the first ｓｅｔof mission needs ａｎｄ　requirements several days ago fｏｒme orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to ａｎｄ　from the International Space Station.Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper ａｎｄ　require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available fｏｒrescue missions by 2010. NASA says the craft should be able to transport injured ｏｒill space station crew members to "definitive(决定性的) medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia ａｎｄ　its seven member crew on February l, 2003.Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working fｏｒyears on a successｏｒto the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.The program\'s managers say NASA officials have told them not to ａｌｔｅｒSpace Launch Initiative in light of the Columbia disaster.U. S. President George W. Bush asked Congress fｏｒabout US$1 billion fｏｒSpace Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane ａｎｄ　Next Generation Launch Technology.The design of the orbiter indicates ____ .【单选题】

A.NASA\'s determination to continue space exploration

B.NASA\'s disadvantage in space technology

C.the great pressure from Congress on NASA

D.a heavy defeat fｏｒNASA

正确答案:A

答案解析:此题问的是设计这架航天飞机表明了什么？选项A的意思是“NASA继续探索太空的决心”。其他几个选项的意思均与原文不符，所以A为答案。

5、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, ａｎｄ　the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson fｏｒthe National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, ａｎｄ　extramarital (婚外的) affairs will be even more common than they are now.But what are the reasons fｏｒthis, ａｎｄ　is the picture really so gloomy (黑暗的)? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based fｏｒyears partly on economic need. Women used to be economically dependent on their husbands--as they usually didn\'t have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic (悲观的) as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together ａｎｄ　don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage ｏｒdivorce statistics. In fact, more than 50% of first marriages survive.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. ａｎｄ　it is also true that married couples have a healthier life than single people: they suffer less from stress ａｎｄ　its consequences, such as heart problems, ａｎｄ　married men generally consider themselves. more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage ａｎｄ　apply it to all of our relationships! (2011年)Why is the outlook of marriage not as hopeless as it appears?【单选题】

A.Many people still like to get married.

B.The rate of divorce has actually decreased.

C.Over 60% of the marriages continue to exist.

D.The statistics of divorce is reliable.

正确答案:A

答案解析:细节考查题。题干问“前景似乎不像人们想的那么悲观的原因”。正确答案为A“很多人仍然想结婚”。离婚率没有下降而是上升了，故I3项与原文信息不符；选项C和D与原文内容不符。
