单选题American society does not treat nap friendly. In fact, says David Dinges, a sleep specialist (专家) at the University Of Pennsylvania School Of Medicine, "There"s even a prohibition against admitting we need sleep". Nobody wants to be caught napping or found asleep at work. To quote a proverb: "Some sleep five hours, nature requires seven, laziness nine and wickedness eleven." "Wrong. The way not to fall asleep at work is to take naps when you need them. We have to totally change our attitude toward napping." says Dr. William Dement of Stanford University, the godfather of sleep research. Last year a national commission led by Dement identified an "American sleep debt" which one member said was as important as the national debt. The commission was concerned about the dangers of sleepiness: people causing industrial accidents or falling asleep while driving. This may be why we have a new sleep policy in the White House. According to recent reports, President Clinton is trying to take a half hour snooze (打盹) every afternoon. About 60 percent of American adults nap when given the opportunity. We seem to have "a mid-afternoon quiet phase" also called "a secondary sleep gate". Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed. Clearly, we were born to nap. We don"t nap to replace shut-eye or to prepare for a night shift. Rather, we snack on sleep, whenever, wherever and at whatever time we feel like it. I myself have napped in buses, cars, planes and on boats, on floors and beds, and in libraries, offices and museums.

单选题{{B}}E{{/B}} Aborigines were earliest known inhabitants of a country. The term is generally applied to the original or native inhabitants of a country, as opposed to a race from another area or colonists and their descendants. Most nations have instituted measures for the welfare of the aborigines within their territories. Such measures include those of the U.S. and Canada concerning Indians and Inuits and those of Australia concerning its aboriginal groups. All aboriginal peoples have been affected by contact with contemporary civilization; in some cases, the introduction of disease, warfare, alcohol, and drugs has demoralized and destroyed peoples. Others, such as the Ainu of northern Japan, have become almost wholly assimilated. The greatest degree of racial mixture has occurred among the native Polynesians of Hawaii. The Indian population of the U.S. has extensively intermarried with whites; those Indians living on reservations retain some traditional Indian folkways. In Central and South America and in the Caribbean region, many tribes have become extinct, in most cases after Spanish or Portuguese conquest. Among aborigines who have kept strong elements of their original identity are the Inuit, Maori, Dayak, and Australian aborigines. Tribes in such comparatively inaccessible areas as the Amazon River Basin of South America still live largely according to their traditional cultures.

单选题{{B}}B{{/B}} The horse came into existence before man on earth. Although the earliest remains of primitive horses have been found on the North American continent, many scientists believe this small species traveled over a land mass. It became extinct (绝种的) in America. Other scientists believe that the horse may have originated in Asia. In any event the animal soon spread into China, Europe, and the Middle East. The first modem horse to be introduced into the American continent came with the early Spanish explorers. Horses were bred into many types. The heavy horses developed in the low countries of Europe and were used for work and by the medieval knights (中世纪骑士) to fide. The oldest breed of horses is said to be the Arabian. The only true wild horses left in 20th century are found in Mongolia. Horses are said to rate in intelligence after the ape, the elephant, the dog. They have excellent memories and can sometimes find their way home when lost, and sense danger better than their masters. The early civilizations of man that had made use of the horse developed more rapidly than those which had not.

单选题One morning a young woman, who has recently lost her first job, was examining the advertisements in the paper in search of other work. Suddenly she called out to her mother, who was in the kitchen. "Listen to this, Mother!" she cried. "I'ye found an easy way of making money." "What is it?" her mother asked, coming into the room. "Listen," said the girl, and read the advertisement aloud: "Do you want to make money? Send me a postal order for five pence, together with a stamped, addressed envelope. You will receive a reply showing you how to make hundreds of pounds without leaving your house." Then there's a name and address. "Nonsense!" said her mother. "You'll only lose five pence and the cost of a postal order and two stamps. If he knows how to do that, why doesn't he do it himself? Why does he need to advertise? You won't get an answer." "Well, five pence isn't much, she said. "I can try." She went to the post-office, bought a postal order, and sent it off.. Two or three days later she received an envelope with a small piece of paper in it. On the paper were four words: "Do as I do./
