单选题What Makes a Soccer Player Great? Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way—was it through training and practice, or are great players' born, not made"? First, these players came from places that have had famous stars in the past---players that a young boy can look up to and try to imitate(效仿). In the history of soccer, only six countries have ever won the World Cup—three from South America and three from Western Europe. There has never been a great national team—or a really great player—from North America or from Asia. Second, these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at game at the age of three or four. Finally, many great players come from the same kind of neighbourhood(聚居区)—a poor, crowded area where a boy's dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer. For example, Liverpool which produced the Beatles(甲壳虫乐队)，had one of the best English soccer teams in recent years. Pele practiced in the street with a "ball" made of rags(破布). And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums(贫民窟)of Belfast. All great players have a lot in common, but that doesn't explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others.

单选题Hercules Once upon a time there was a great Greek hero, Hercules. He was taller and stronger than anyone you have ever seen. On his shoulder he carried a club and in his hand he held a bow (弓). He was known as the hero of a hundred adventures. Hercules served a king. The king was afraid of him. So again and again he sent him on difficult tasks. One morning the king sent for him and told him to fetch three golden apples for him from the garden of the Singing Maidens (歌女). But no one knew where the garden was. So Hercules went away. He walked the whole day and the next day and the next. He walked for months before he saw mountains far in the distance one fine morning. One of the mountains was in the shape of a man, with long, long legs and arms and huge shoulders and a huge head. He was holding up the sky. Hercules knew it was Atlas, the Mountain God. So he asked him for help. Atlas answered, "My head and arms and shoulders all ache. Could you hold up the sky while I fetch the golden apples for you?" Hercules climbed the mountain and shouldered the sky. Soon the sky grew very heavy. When finally Atlas came back with three golden apples, he said, "Well, you are going to carry the mountain for ever. I'm going to see the king with the apples. "Hercules knew that he couldn't fight him because of the sky on his back. So he shouted: "Just one minute's help. My shoulders are hurting. Hold the sky for a minute while I make a cushion (垫子) for my shoulders." Atlas believed him. He threw down the apples and held up the sky. Hercules picked up the apples and ran back to see the king.

单选题Eating Meat—Less or More? Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one"s diet is nutritionally, environmentally, and ethically beneficial. People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to A Teen"s Guide to Going Vegetarian, by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier. Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the corn and 95% of the oats grown in the U.S. are fed to livestock. The world"s cattle alone consume enough food to equal the caloric needs of 8.7 billion people, more than the entire human population. One half of the water used in the Unites States also goes to livestock; 250 gallons of water produces only 1 lb. (镑) of beef. If people eat less meat and more plants, the amount of available food will increase. Many people become vegetarians because they feel that eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half a square foot of space each, and since they are raised so close together, a lot of blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise, pigs that are repressed will bite each other"s tails, so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the health of people, and to the health of the world.

单选题Plants and Mankind Botany, the study of plants, occupies a peculiar position in the history of human knowledge. We don"t know what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and many other purposes. Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each. To them botany has no name and is probably not even recognized as a special branch of "knowledge" at all. Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the marvel of agriculture: cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin to fade away.

单选题 Cell Phone Lets Your Secret Out Your cell phone holds secrets about you. Besides the names and {{U}} {{U}} 1 {{/U}} {{/U}}that you've programmed into it, traces of your DNA linger on the device, according to a new study. DNA is genetic material that {{U}} {{U}} 2 {{/U}} {{/U}}in every cell. Like your fingerprint, your DNA is unique to you—{{U}} {{U}} 3 {{/U}} {{/U}}you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left {{U}} {{U}} 4 {{/U}} {{/U}}at the scene of a crime. The results often help detectives identify {{U}} {{U}} 5 {{/U}} {{/U}}and their victims. Your cell phone can reveal more about you {{U}} {{U}} 6 {{/U}} {{/U}}you might think. Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the {{U}} {{U}} 7 {{/U}} {{/U}}. This made her wonder whether traces of DNA lingered on cell phones-even when no blood was involved. {{U}} {{U}} 8 {{/U}} {{/U}}she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect {{U}} {{U}} 9 {{/U}} {{/U}}traces of the users from two parts of the phone: the outside, where the user holds it, and the {{U}} {{U}} 10 {{/U}} {{/U}}, which is placed at the user's ear. The scientists scrubbed the phones using a solution made mostly {{U}} {{U}} 11 {{/U}} {{/U}}alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones {{U}} {{U}} 12 {{/U}} {{/U}}for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more. The scientists discovered DNA that {{U}} {{U}} 13 {{/U}} {{/U}}to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, but those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. {{U}} {{U}} 14 {{/U}} {{/U}}, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device.

单选题 阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 {{B}}Hierarchy{{/B}} Culture is the sum total of all the traditions, customs, beliefs, and ways of life of a given group of human beings. In this sense every group has a culture however savage, undeveloped, or uncivilized it may seem to us. To the professional anthropologist, there is no intrinsic superiority of one culture over another, just as to the professional linguist there is no intrinsic hierarchy among languages. People once thought of the languages of backward groups as savage, undeveloped forms of speech, consisting largely of grunts (呼噜声) and groans (呻吟). While it is possible that language in general began as a series of grunts and groans, it is a fact established by the study of "backward" languages that no spoken tongue answers that description today. Most languages of uncivilized groups are, by our most severe standards, extremely complex, delicate, and ingenious pieces of machinery for the transfer of ideas. They fall behind our Western languages not in their sound patterns or grammatical structures, which usually are fully adequate for all language needs, but only in their vocabularies, which reflect the objects and activities known to their speakers. Even in this department, however, two things are to be noted: (1) All languages seem to possess the machinery for vocabulary expansion, either by putting together words already in existence or by borrowing them from other languages and adapting them to their own system. (2)The objects and activities requiring names and distinctions in "backward" languages; while different form ours, are often surprisingly numerous and complicated. A Western language distinguishes merely between two degrees of remoteness ("this" and "that"); some languages of the American Indians distinguish between what is close to the speaker, or to the person addressed, or removed from both, or out of sight, or in the past, or in the future. This study of language, in turn, casts a new light upon the claim of the anthropologists that all cultures are to be viewed independently, and without ideas of rank or hierarchy.

单选题Climate Change Poses Major Risks for Unprepared Cities A new examination of urban policies has been 1 recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and 2 development. She warns that many of the world"s fast-growing urban areas, especially in developing countries, will likely suffer from the impacts of changing climate. Her work also concludes that most cities are failing to 3 emissions of carbon dioxide and other greenhouse 4 . These gases are known to affect the atmosphere. "Climate change is a deeply local issue and poses profound threats to the growing cities of the world." says Romero Lankao. "But few cities are developing effective strategies to 5 their residents." Cities are 6 sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao"s findings highlight ways in which city residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term 7 . The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential 8 associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 9 paved cities more than surrounding areas. The impacts of such natural events can be more serious in an urban environment. For example, a prolonged heat wave can increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may 10 facilities such as drinking water or a dependable network of roads, are especially vulnerable to natural disasters. Many residents in poorer countries live in substandard housing 11 access to reliable drinking water, roads and basic services. Local governments, 12 , should take measures to protect their residents. "Unfortunately, they tend to move towards rhetoric 13 meaningful responses," Romero Lankao writes. They don"t impose construction standards that could reduce heating and air conditioning needs. They don"t emphasize mass transit and reduce 14 use. In fact, many local governments are taking a hands-off approach. Thus, she urges them to Change their 15 policies and take strong steps to prevent the harmful effects of climate change on cities.

单选题A Country's Standard of Living The "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 (51) first on its capacity to produce wealth. "Wealth" in this (52) 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 (53) wealth depends upon many factors, most of (54) have an effect on one another. Wealth depends (55) a great extent upon a country's natural resources. Some regions of the world are well supplied with coal and minerals, and have fertile soil and a favorable climate; other regions (56) none of them. Next to natural resources comes the ability to (57) them to use. China is perhaps as rich as the USA in natural resources, but suffered for many years (58) civil and external wars and for this and other (59) was unable to develop her resources. Sound and stable political conditions, and (60) from foreign invasions, enable a country to develop its natural resources peacefully and steadily, and to produce more (61) than another country equally well favored by nature but less well ordered. A country's standard of living does not only depend upon the wealth that is produced and (62) within its own borders, but also upon what is directly produced through international trade, for example, Britain's wealth in foodstuffs and other agricultural (63) would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (过剩的) manufactured goods to be traded abroad for the agricultural products (64) would otherwise be lacking. A country's wealth is, therefore, much influenced by its manufacturing capacity (65) that other countries can be found ready to accept its manufactures.
