单选题Faces, like fingerprints, are unique. Have you ever wondered how it is possible for us to find out people? Even a skilled novelist probably could not make a description of all the features(特征) that make one face different from another. Yet a very young kid or even an animal, such as a pigeon,can learn to recognize faces. We all take the ability for granted. We can also tell people apart by which ways they behave. When talking of someone's personality, we mean the methods in which he or she acts, speaks, thinks or feels that make him or her different from others. Like the human face, human personality is so complicated. But describing someone's personality in words is somewhat much easier than describing his face. If you were asked to describe what a "nice face" looked like, you probably would have a lot of difficulties. But if you were asked to describe a "nice person" you might begin to think about someone who was kind, considerate, friendly, generous,and so forth. There are many words to describe what a person's thought is and how a person feels and acts. Gordon, an American psychologist found nearly 18, 000 English words characterizing differences in people's behavior. And many of us use such terms as bookworms, conservatives to describe one's personality. People have always tried to "type" each other. Actors, on early Greek theater stage wore masks to show the audience whether they played the villain's(坏人) or the hero's role. In reality, the words "person" and "personality" come from the Latin "persona", meaning "mask". Nowadays, most television and movie actors do not wear masks. But we can easily tell the "good guys" from the "bad guys" for the reason that the two types differ in appearances as well as in actions.

单选题{{B}}Text 1{{/B}} Art is fun; it caters to the basic creative instinct which is present in everyone. It can impart a great feeling of achievement especially to children who as yet have not been able to gain much of a sense of success from their other efforts in life. It also helps backward children to develop mentally and physically. Their confidence grows as they experience success in art, and a confident child learns more easily than a tense one. Physically handicapped children benefit because their motor control improves as they attempt to make more delicate movements with their hands and as they gradually impose more control upon themselves. Art is particularly valuable to mentally handicapped children who find it difficult to communicate their ideas and emotions and who perhaps even find it difficult to comprehend themselves. Subnormal children with very limited vocabularies may find that painting is easier than talking, and through painting they are able to express ideas, emotions, and reactions to situations and experiences. Children need to communicate in two ways. First, they have to convey information to other people, often about their immediate requirements concerning both tangible things— "I want to drink." or "I want to mention." —and less tangible things— "I want you near me." Secondly, they have to communicate with themselves. If children, do not have words to use, their minds are, inevitably, a disorderly mixture of responses to which they can react only emotionally, often with frustrations. Through their paintings such children are not consciously trying to tell other people that they have certain feelings, but with the paint they are able to create a concrete, permanent statement of feeling and so the emotion becomes less intense and under more control. Thus, art helps in the same way that acting and fantasy-play help children to regulate their emotions and recreations, i. e. , by recreating them in a controlled situation. Music, dancing, acting, and storytelling can give similar feelings of satisfaction and offer opportunities which may be of assistance to children either individually or collectively.

单选题 There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a "greenhouse effect"—conserving heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water. Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth's temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world's temperature will stay about the same as it is now. Driven by economic profit, people neglect the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?

单选题{{B}}Text 3{{/B}} Do you find it very difficult and painful to get up in the morning? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as: "Get up, Peter! You'll be late for work again!" The possible explanation to the trouble is that Peter is at his temperature-and-energy peak in the evening. Much family quarrel ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning, but yon have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point. Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

单选题 Questions 23～25 are based on the following story about a dog.

单选题 Even plants can run a fever, especially when they' re under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3 000 feet away—straight up. A decade ago, adapting the infrared(红外线)scanning technology developed for military purposes and other satelities, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones were under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest(害虫)problems. Even better, Paley' s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray ,using 50 to 70 percent less pesticide than they otherwise would. The bad news is that Paley' s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt that the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
