1、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 or any other vegetable or fruit 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 for the 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 a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime 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. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.What does "malignancy" in the text refer to?【单选题】

A.Cancer.

B.Sickness.

C.Vitamins.

D.Disease.

正确答案:A

答案解析:这是一个很生僻的词，很少有考生认识，但是根据第1句话，“在众多的malignancy中，肺癌是最大的杀手”，这说明它是“癌症”。因此答案是A。

2、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 donor gave his or her heart, he or she would obviously and necessarily die (or be 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 donor were 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 donor would 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 or proportion of successful operations and this, in turn, has led to greater demand for transplants. 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 for organs, a new moral dilemma has emerged. For example, in the United States there are many people who would survive iflungs were available for transplanting. In fact, about 80% of them die before a suitable donor is found. In these circumstances who would decide if a donor were found whose lungs were equally suitable for two potential recipients?This problem is made worse by the fact that many patients, or their families, become desperate to find a donor. Some succeed in publicizing their situation in newspapers, to politicians or on 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? Or the donor? Or the 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 or death to the patients involved.How do you think the dilemma will develop?【单选题】

A.The dilemma will remain unresolved.

B.The public will demand a fair resolution.

C.Those who are more desperate to find a donor will always be successful.

D.The doctors will have the final say.

正确答案:A

答案解析:文章没有提出解决办法，因此选A。

3、G8 SummitLeaders of the Group of Eight Major Industrialized Nations (G8) will meet in Scotland in July this year. Representatives from China, India, Mexico, South Africa and Brazil have also been invited. Here\'s what the G8 leaders want from the meeting.British Prime Minister Tony Blair wants the G8 to cancel debt to the world\'s poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers and removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests. On climate change, Blair wants concerted (共同的) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn\'t like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol(《京都议定书》). Although the US is the world\'s biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem.French President Jacques Chirac supports Blair on Africa and climate change. He is determined to get the US to sign the climate change deal.German Chancellor Gerhard Schroder remains doubtful of Blair\'s Africa proposals. Schroder\'s officials have dismissed the notion that money will solve Africa\'s problems as"old thinking". Berlin says that African states should only receive extra money if they can prove they\'ve solved the corruption problem.Russian President Vladimir Putin was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Putin intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet Republics of Georgia, Uzbekistan, Tajikistan and Moldova.Japanese Prime Minister Junichiro Koizumi\'s priorities are a seat on the UN Security Council, for which he will be lobbying (游说) at the summit. And he\'s concerned about the Democratic People\'s Republic of Korea\'s nuclear weapons programme.India has accepted the invitation to attend the G8 meeting.【单选题】

4、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural ____ would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】

6、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.There is a tension between babysitting and hurting.【单选题】

9、Britain\'s Solo SailorEllen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money for three years to buy her first small sailing boat. When she was 18, she sailed alone around Britain and won the "Young Sailor of the Year" award.Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors and she was given a very warm welcome when she returned.Ambition and determination have always been a big part of Ellen\'s personality. When she was younger, she lived in a kind of hut (棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race. Then she took a one - way ticket to France, bought a tiny seven meter Class Mini yacht (游艇), slept under it while she was repairing it, and then she raced it 4,000 kilometres across the Atlantic in 1997, alone for 33 days.Ellen has to learn many things, because sailing single - handed means that she has to be her own captain, electrician, sailmaker, engineer, doctor, journalist, cameraman and cooker, She also has to be very fit, and because of the dangers of sleeping for long periods of time she\'s in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time.And she needs courage. Once, in the middle of the ocean, she had to climb the mast (桅杆) of a boat to repair the sails at four o\'clock in the morning, with 100 kph winds blowing around her. It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It\'s hard to describe how it feels to be up there. It\'s like trying to hold onto a big pole, which for me is just too big to get my arms around, with someone kicking you all the time and trying to shake you off".But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean and having the chance to live this. I just feel lucky to be here."The word "solo" in the title could be best replaced by ____. 【单选题】

A.single - handed

C.one performer

D.self - starter

正确答案:A

答案解析:本题是词义题，难度不大，考查的是基本意义，不需要查询引申意义。此外，文中第四段开头，because sailing single - handed means ……“Ellen必须学会许多事情，因为单独航行意味着……”A复制了文章原话，是答案。

10、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 for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times and extramarital affairs will be even more common than they are now.But what are the reasons for this, and is the picture really so gloomy? 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 for years 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 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 cohabit and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages.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!What does "this is no longer the case" in paragraph two mean?【单选题】

A.It is not necessary to get married any more.

B.Women do not need a husband any longer.

C.Women are not economically dependant any more.

D.Many wives do well-paying jobs outside home now.

正确答案:C

答案解析:第2段第4句、第5句说得很清楚，妇女们如今在外工作在经济上不再依赖她们的丈夫，觉得无须维持行失败的婚姻。
