单选题 Why don't birds get lost on their long migratory flight? Scientists have puzzled over this question for many years. Now they're beginning to fill in the blanks. Not long ago, experiments show that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights. One such bird--a warbler--had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their principle means of navigation. What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coastlines, and river courses. But when it's too dark to see these, the warblers circle helplessly, unable to get their bearings.

单选题 Psychology is the study of the mind and mental activities. For example, psychologists are interested in why some things make you sad, but others make you happy. They want to know why some people are shy, but others are quite talkative. They also want to know why people do the things that they do. They test intelligence. Psychologists deal with the minds and behavior of people. Your mind consists of all your feelings, thoughts, and ideas. It is the result of one part of the brain called the cerebrum (大脑). Your behavior is the way you act or conduct yourself. Examples of behavior include shouting, crying, laughing and sleeping. Several people have been instrumental in the field of psychology. Wilhelm Wundt set up the first psychological laboratory in Leipzig, Germany, in 1879. Ivan Pavlov, a Russian, is noted for his experiments with dogs in which he studied their reflexes (反射作用) and reactions. Around 1900, Sigmund Freud stated his theory that people try to repress any memo- ties or thoughts that they believed were not good. Psychologists should not be confused with psychiatrists. Psychiatrists deal only with mental illness. They are medical doctors who treat people.

You should write your answers briefly (in no more than 3 words) on the Answer Sheet correspondingly. Instead of using dye to color cotton, a woman cotton breeder is letting nature do the work. Through crossbreeding ( 杂交 ), Sally Fox of Natural Cotton Colours in Wickenberg is creating plants that yield fiber in a variety of colors. Because no dye is required, production of the naturally colored cotton conserves water and reduces pollution. Fox recently received a United Nations award for her work. Organically farmed brown and green cottons are already being used to make clothing sold by Levi Strauss, Esprit, and L. L. Bean. The naturally colored cottons are more expensive than conventional cottons, but they do not fade in the laundry. Fox is also developing a white cotton that can be grown organically. Normally, harvesting white cotton without a chemical defoliant (脱叶剂 ) is extremely difficult, because resin (树脂) on the leaves will stain the fibers. But Fox is growing a variety that naturally sheds (脱去) its leaves prior to harvest. The cotton, close to commercialization, bears long fibers that will be used to make high-quality textile.

单选题The greatest changes have been in the lives of women. During the twentieth century there was a remarkable shortening of the time in a woman's life spent caring for children. A woman marrying at the end of the nineteenth century would probably have been in her mid twenties, and would be likely to have seven or eight children, of whom four or five would live till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which time her state of health made it unusual for her to get paid work. Today women marry younger and have fewer children. Usually a woman's youngest child will be fifteen when she is forty-five and she can expect to live another thirty years during which time she is likely to take paid work until her retirement at sixty. Even when she has to take care of her children, her work is lightened by modern living conditions. This important change in a woman's life pattern has only recently begun to have its full effect on woman's economic position. Even a few years ago most girls left school at the first opportunity, and most of them took a full time job. However, when they married, they usually left work at once and never went back to it. Today the school-leaving age is sixteen, many girls carry on working at school after that age, and though women usually marry younger, more married women carry on working at least until shortly before their first child is born. Very many more later return to full or part-time jobs. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life, and with both husband and wife sharing more equally the responsibility providing money for living expenses, and running the house, according to the abilities and interests of each of them.

单选题In the same way that a child must be able to move his arms and legs before he can learn to walk, the child must physiologically be capable of producing and experiencing particular emotions before these emotions can be modified through learning. Psychologists have found that there are two basic processes by which learning takes place. One kind of learning is called classical conditioning. This occurs when one event or stimulus is consistently paired with, or followed by, a reward or punishment. It is through classical conditioning that a child learns to associate his mother"s face and voice with happiness and love, for he learns that this person provides food and comfort. Negative emotions are learned in a similar fashion. The second kind of learning is called "operant conditioning". This occurs when an individual learns to do things that produce rewards in his environment and learns not to do things that produce punishments. For example, if a mother always attends to her baby when he cries and cuddles him until he is quiet, she may teach him that if he cries he will get attention from mother. Thus, the baby will learn to increase his crying in order to have his mother more. Every day, we grow and have new experiences. We constantly learn by reading, watching television, interacting with other people, and so forth. This learning affects our emotions. Why is it that we learn to like some people and dislike others? If a person is nice to us, cares about us, we learn to associate this person with positive feelings, such as joy, happiness, and friendliness. On the other hand, if a person is mean to us, does not care about us, and even deliberately does things to harm us, we learn to associate this person with negative feelings, such as unhappiness, discomfort, and anger.
