单选题The Greek's lofty attitude toward scientific research—and the scientists' contempt of utility—was a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry inhibited fundamental technological progress and in some areas repressed it altogether. But there was a still greater obstacle to change until the very end of the middle ages: the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages(and in some areas much longer)itself hampered improvement. Under this system, the laboring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few—priests, nobles, and kings—concerned themselves only with ownership and maintenance of their own position. In the interest of their privileges they did achieve considerable progress in defense, in warmaking, in government, in trade, in the arts of leisure, and in the extraction of labor from their dependents, but they had no familiarity with the process of production. On the other hand, the laborers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved. The whole ancient world was built upon this relationship—a relationship as sterile as it was inhuman. The availability of slaves nullified the need for more efficient machinery. In many of the commonplace fields of human endeavor, actual stagnation prevailed for thousands of years. Not all the glory that was Greece and the grandeur that was Rome could develop the windmill or contrive so simple an instrument as the wheelbarrow—products of the tenth and thirteenth centuries respectively. For about twenty-five centuries, two-thirds of the power of the horse was lost because he wasn't shod, and much of the strength of the ox was wasted because his harness wasn't modified to fit his shoulders. For more than five thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkably little alteration(in the thirteenth century)to become a rudder. With any ingenuity at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it—but the ingenuity wasn't forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed thatched roof of his one-room dwelling(which he shared with his animals), while the medieval charcoal burner(like his Stone Age ancestor)made himself a hut of small branches.

单选题Hippies were members of a youth movement of the 1960's and 1970's that started in the United States and spread to Canada, Great Britain, and many other countries. The hippies rejected the customs, traditions, and life styles of society and tried to develop those of their own. Most hippies came from white middle-class families and ranged in age from 15 to 25 years old. They thought too many adults cared about making money and little else. The term hippie may come from the word hip, which means "turned-in" or aware. Hippies wanted a world based on love of humanity and peace. Many believed that wonderful, magical changes were about to take place. They thought these changes would happen as soon as people learned to express their feelings honestly and to behave naturally at all times. Hippies strongly opposed U.S. involvement in the Vietnam War. Many hippies lived together in small groups, working with one another and sharing possessions. Others refused to be tied down to a fixed job or home. They wandered from place to place seeking part-time work and temporary shelter. Some begged for spare change and lived in the streets or camped in parks or other public lands. Hippies were sometimes called "flower children" because they gave people flowers to communicate gentleness and love. They let their hair grow long and walked barefoot or in sandals. Hippies attracted public attention by wearing clothing that featured unusual combinations of colors and textures. A large number of hippies used marijuana, LSD, and other drugs. Drug experiences shaped many of their symbols and ideas. The Beatles, a popular English rock group, helped spread the hippie movement with their song. Hippie favorites included such other rock groups as the Grateful Dead and the Jefferson Airplane, singers Joan Baez and Bob Dylan, poet Allen Ginsberg, and novelist Ken Kesey. Many hippies admired Timothy Leary, a psychologist who preached salvation through the use of drugs. In time, most hippies realized it was not easy to reform society by "dropping'out" of it. Some joined more organized political movements to work for specific social causes. Others turned to spirituality or religion. The majority simply left the hippie stage of their lives behind while trying to hold on to at least a few of the ideals that once inspired them.

单选题{{B}}Passage Two{{/B}} In June of 1973, nine whales beached on the Florida coast. Beaching means swimming out of the ocean onto the beach, and usually dying there. No one knows why they do it, but a number of whales beach themselves every year. Some people think beaching is an accident. Perhaps the whales get confused. Scientists who studied the beaching of three dozen whales in Australia think the whales may have been confused by loud noises, Whales can tell where they are by sounds. They send out sounds and listen as they travel past or bounce off objects. Two days before these thirty-six whales beached, loud guns had been fired for two hours. The loud sounds may have confused the whales. Their confusion might have caused them to wander into low water. Whatever the reason whales beach, it is a sad event. People try to save them, but very few beached whales live. One whale that was rescued from beaching in Florida lived for forty-five days. That is the longest a beached whale has ever survived. And it lived that long only because it got attention from doctors. All over the world, scientists rush to whale beachings as soon as they hear about them. They hope to learn why whales beach, and how to save them.
