单选题Sport or Spectacle? Muhammad Ali is probably the most famous sports figure on earth: he is recognized on every continent and by all generations. The diagnosis of his illness (51) Parlonson's disease after his retirement fuelled the debate about the dangers of boxing and criticism (52) the sport. That, plus his outspoken opposition (53) women's boxing, made people wonder how he would react when one of his daughters decided to take (54) the sport. His presence at Laila's first professional fight, (55) _, seemed to broadcast her father's support. Of course Muhammnad Ali wanted to watch his daughter fight. The ring announcer introduced him as the "the greatest" and as he sat down at the ringside the crowd chanted. Twenty-one-year-old Laila's debut fight was a huge success and there was as much publicity for the fight (56) her father's fights once attracted. (57) , Laila's opponent was much weaker than she was and the fight lasted just 31 seconds. Since then, Laila has won most of her fights by knocking out her opponent. "She knows (58) she's doing, all fight, "said one referee about her. "She knows about moving well. You can see some of her dad's moves." Laila Ali would rather not compare herself (59) her father. She prefers to make her own (60) . Her father supports her decision to enter the sport but he has not spared her the details of what can happen. Laila realizes that her father wants her to understand the (61) possible scenario to see (62) she still wants to go forward with it. She knows she's going to get hit hard at times, that she may get a broken nose or a swollen face, but at least she is prepared for it. Laila's decision to start boxing (63) her father's struggle with the symptoms of Parkinson's disease has of course sparked a mixture of debate and (64) . But Laila is a feisty and determined individual and it is that as much as her famous last name that has made her a magnet for worldwide media attention. Of course, the (65) on the boxing scene of a woman with her family history attracts even more questions about whether women's boxing is sport or spectacle．

单选题Natural Food as Choice of Healthy Diet Increasingly, over the past ten years, people—especially young people—have become aware of the need to change their eating habits, because 1 of the food they eat, particularly processed foods, is not good for health. Consequently, there has been a 2 interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers widely used in farming today. Natural foods, for example, are vegetables, fruit and grain 3 have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it 4 essential vitamins and minerals. This in itself is a natural process 5 with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the 6 of foods grown in commercial farming areas. Natural foods also include animals which have been allowed to feed and move 7 in healthy pastures. Compare this with what happens in the mass production of poultry: there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better 8 rubbish. Chickens kept in this way are not only 9 as food; they also produce eggs which lack important vitamins. There are other aspects of healthy eating which are now receiving increasing 10 from experts on diet. Take, for example, the question of sugar. This is actually a nonessential food! 11 a natural alternative, such as honey, can be used to sweeten food if this is necessary, we can in fact do 12 it. It is not that sugar is harmful in itself. But it does seem to be additive: the quantity we use has grown steadily over the last centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is to provide us with energy, in the 13 of calories. There are no vitamins in it, no minerals and no fiber. It is significant that nowadays fiber is considered to be an important part of a healthy diet. In white bread, for example, the fiber has been removed. But it is 14 in unrefined flour and of course in vegetables. It is interesting to note that in countries where the national diet 15 large quantities of unrefined flour and vegetables, certain diseases are comparatively rare. Hence the emphasis is placed on the eating of whole meal bread and more vegetables by modern experts on "healthy eating".

单选题{{B}}第三篇{{/B}} {{B}} Early or Later Day Care{{/B}} The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion. Firstly, anthropologists point out that the insulated love affair between children and parents found in modem societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, (he father and mother of a child did not rear their infant alone -- far from it. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue. But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.

单选题A Gay Biologist Molecular biologist Dean Hamer has blue eyes, light brown hair and a good sense of humor. He smokes cigarettes, spends long hours in an old laboratory at the U.S. National Institute of Health, and in his free time climbs up cliffs and points his skis down steep slopes. He also happens to be openly, matter-of-fact gay. What is it that makes Hamer who he is? What, for that matter, accounts for the talents and traits that make up anyone"s personality? Hamer is not content merely to ask such questions; he is trying to answer them as well. A pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. To a remarkable extent, his work on what might be called the gay, thrill- seeking and quit-smoking genes reflects how own genetic predispositions. That work, which has appeared mostly in scientific journals, has been gathered into an accessible and quite readable form in Hamer"s creative new book, Living, with Our Genes. "You have about as much choice in some aspect of your personality," Hamer and coauthor Peter Copeland write in the introductory chapter, "as you do in the shape of your nose or the size of your feet." Until recently, research into behavioral genetics was dominated by psychiatrists and psychologists, who based their most compelling conclusions about the importance of genes on studies of identical twins. For example, psychologist Michael Bailey of Northwestern University famously demonstrated that if one identical twin is gay, there is about a 50% likelihood that the other will be too. Seven years ago, Hamer picked up where the twin studies left off, homing in on specific strips of DNA that appear to influence everything from mood to sexual orientation. Hamer switched to behavioral genetics from basic research, after receiving his doctorate from Harvard, he spent more than a decade studying the biochemistry of a protein that cells use to metabolize heavy metals like copper and zinc. As he was about to turn 40, however, Hamer suddenly realized he had learned as much about the protein as he cared to. "Frankly, I was bored," he remembers, "and ready for something new." Homosexual behavior, in particular, seemed ripe for exploration because few scientists had dared tackle such an emotionally and politically charged subject. "I"m gay," Hamer says with a shrug, "but that was not a major motivation. It was more of a question of intellectual curiosity—and the fact that no one else was doing this sort of research. "

单选题Medical Education In 18th. century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Parisand Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King's College(now Columbia University), the first institution in the colonies to give the degree of doctor of medicine. Following the American Revolution, the Columbia medical faculty(formerly of King's College) was combined with the College of Physicians and Surgeons, chartered in 1809, which survives as a division of Columbia University. In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary(私营的)schools of medicine run for personal profit. most of which had low standards and poor facilities In 1910 Abraham Flexner. the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools Subsequently the American Medical Association(AMA)and the Association of American Medical Colleges(AAMC)laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals, and licensing of medical practitioners(开业医师)that survive to this day. By the late 1980s the US and Canada had 142 4. year medical colleges recognized by the Liaison(联络) Committee on Medical Education to offer che M. D. degree；during the 1987-88 academic year,47,262 men and 25,686 women entered these colleges and an estimated 11, 752 men and 5, 958 women were graduated. Graduates, after a year of internship(实习期), receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners

单选题Dining Custom Every land has its own dining custom, and the United States is no exception. Americans feel that the first rule of being a polite guest is to be on time. If a person is invited to dinner at 6:30, the hostess expects him to be there at 6:30 or not more than a few minutes after. Because she usually does her own cooking, she times the meal so that the coffee and meat will be at their best at the time she asks the guest to come. If he is late, the food will not be so good, and the hostess will be disappointed. When the guest cannot come on time, he calls his host or hostess on the telephone, gives the reason, and tells at what time he thinks he can come. As guests continue to arrive, the men in the group stand when a woman enters and remain standing until she has found a chair. A man always rises when he is being introduced to a woman. A woman does not rise when she is being introduced either to a man or a woman unless the woman is much older. When the guests sit down at a dinner table, it is customary for the men to help the ladies by pushing their chairs under them. Even an American may be confused by the number of knives, forks, and spoons beside his plate when he sits down to a formal dinner. The rule is simple, however: use them in the order in which they lie, beginning from the outside. Or watch the hostess and do what she does. The small fork on the outside on the left is for salad, which is often served with the soup. The spoon on the outside at the right is for soup, and so on. Sometimes there is a separate little knife, called a butter spreader, on a small bread-and-butter plate at the left. As the bread is passed, each guest puts his piece on the bread-and-butter plate.

单选题What Should I Say to the Person Who Has Cancer? It is normal to feel that you don"t know what to say to someone who has cancer. You might only know the person casually, or you may have worked 1 or lived near each other for many years and have a closer relationship. The most important 2 you can do is to acknowledge the situation in some way—whatever is most comfortable for you. You can show interest and concern, you can express encouragement, or you 3 offer support. Sometimes the simplest expressions of concern are the 1 meaningful. While it is good to be encouraging, it is also important 5 to show false optimism or to tell the person with cancer to always have a positive attitude. Doing 6 things may discount their fears, concerns, or sad feelings. It is also tempting to say that you know 7 the person feels. While you may know this is a difficult time, no one can know exactly how the person with 8 feels. Humor can be an important way 9 coping. It is also another source of support and encouragement. Let the person with cancer 10 the lead; it is healthy if they find something funny about a side effect, like hair loss or increased appetite, and you can certainly join 11 in a good laugh. This can be a great way to relieve stress and to take a break from the 12 serious nature of the situation. When the person with cancer looks good, let them know! Refrain (忍住) 13 comments when their appearance isn"t as good, such as "You"re looking pale," or "You"ve lost weight." Cancer and its treatment can be very unpredictable. Be prepared for good days and bad 14 . Refrain from telling the person with cancer stories about family members or friends who have had cancer. Everyone is different, and these stories may not be helpful. Instead, it is better simply to tell them you know 15 about cancer because you"ve been through it with someone else.

单选题"OH DEAR! Oh dear! I shall be too late!" So muttered the White Rabbit just before he plunged into Wonderland, with Alice in pursuit. Similar utterances have been escaping the lips of European physicists, as it was confirmed last week that their own subterranean Wonderland, a new machine called the Large Hadron Collider, will not now begin work until May 2008. This delay may enable their American rivals to scoop them by finding the Higgs boson—predicted 43 years ago by Peter Higgs of Edinburgh University to be the reason why matter has mass, but not yet actually discovered. The Large Hadron Collider is a 27km-long circular accelerator that is being bulk at CERN, the European particle-physics laboratory near Geneva, specifically to look for the Higgs boson. When it eventually starts work, it will be the world"s most powerful particle collider. It will also be the most expensive, having cost $ 8 billion to build. The laboratory had hoped it would be ready in 2005, but the schedule has slipped repeatedly. The most recent delay came at the end of March, with the dramatic failure of a magnet assembly that had been supplied by CERN"s American counterpart, the Fermi National Accelerator Laboratory (Fermi lab) near Chicago. This device was one of four designed to focus beams of particles before they collide in the experimental areas. Admittedly, it had been placed under extreme conditions when it failed, but such forces are to be expected from time to time when the machine is running normally. The magnets have yet to be fixed, although physicists think they know how to do it. Other, smaller hitches have compounded the problem. The collider has been built in eight sections, each of which must be cooled to temperatures only just above absolute zero. This is because the magnets used to accelerate the particles to the high energies needed for particle physics rely on the phenomenon of superconductivity to work—and superconductivity, in turn, needs extremely low temperatures. Unfortunately, the first of the eight sections took far longer to chill than had been expected. If, as the other seven sections are cooled, further problems emerge, the start date will have to be put back still further. It takes a month to cool each section, and a month to warm each one back up to normal temperatures again. If it took, say, a month to fix any problems identified as a section cooled, each cycle would postpone the start date by three months. To accelerate progress (as well as particles), CERN"s management decided last week to cancel an engineering run scheduled for November. Instead of beginning slowly with some safe-but-dull low-energy collisions, the machine"s first run will accelerate its particles to high energies straight away. Such haste may be wise, for rumours are circulating that physicists working at the Tevatron, which is based at Fermi lab and is currently the world"s most powerful collider, have been seeing hints of the Higgs boson. Finding it would virtually guarantee the discoverer a Nobel prize—shared jointly, no doubt, with Dr. Higgs. Hence the rush, as hundreds of physicists head down the rabbit hole, seeking their own adventures in Wonderland.

单选题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 1 in Antarctica in 1983. We encounter an interesting situation when we discuss temperatures in 2 temperatures in Earth orbit actually range from about 20℃ to 120℃. The temperature depends upon 3 you are in direct sunlight or shade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space 4 that protect astronauts from these temperature extremes. The space temperatures just discussed affect only our areal of the solar 5 . 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 6 . We are taught it is supposedly 7 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 to a temperature barely 8 absolute zero. They won a Nobel Prize in Physics in 2001 for their work—not a discovery, in this case. Why is the two scientists work so important to science? In the 1920s, Satyendra Nath Bose was studying an interesting 9 about special light particles we now call photons. Bose had trouble 10 other scientists to believe his theory, 11 he contacted Albert Einstein. Einstein"s calculations helped him theorize that atoms 12 behave as Bose thought--but only at very cold temperatures. Scientists have also discovered that 13 atoms can help them make the world"s atomic docks even more accurate. These clocks are so accurate today they would only lose one second 14 six million years! Such accuracy will help us travel in space because distance is velocity times time (d=v×t). With the long distances involved in space 15 , we need to know time as accurately as possible to get accurate distance.
