单选题{{B}}Text 2{{/B}} When a 13-year-old Virginia girl started sneezing, her parents thought it was merely a cold. But when the sneezes continued for hours, they called in a doctor. Nearly two months later the girl was still sneezing, thousands of times a day, and her case had attracted world-wide attention. Hundreds of suggestions, ranging from "put a clothes pin on her nose" to "have her stand on her head" poured in. But nothing did any good. Finally, she was taken to Johns Hopkins Hospital where Dr Leo Kanner, one of the world's top authorities on sneezing, solved the baffling problem with great speed. He used neither drugs nor surgery for, curiously enough, the clue for the treatment was found in an ancient superstition about the amazing bodily reaction we call the sneeze. It was all in her mind, be said, a view which Aristotle, some 3 000 years earlier, would have agreed with heartily. Dr Kanner simply gave a modern psychological interpretation to the ancient belief that too much sneezing was an indication that the spirit was troubled; and he began to treat the girl accordingly. "Less than two days in a hospital room, a plan for better scholastic and vocational adjustment, and reassurance about her unreasonable fear of tuberculosis quickly changed her from a sneezer to an ex-sneezer," he reported. Sneezing has always been a subject of wonder, awe and puzzlement. Dr Kanner has collected thousands of superstitions concerning it. The most universal one is the custom of begging for the blessing of God when a person sneezes -- a practice Dr Kanner traces back to the ancient belief that a sneeze was an indication that the sneezer was possessed of an evil spirit. Strangely, people all over the world still continue the custom with the traditional "God bless you" or its equivalent. When scientists look at the sneeze, they see a remarkable mechanism which, without any conscious help from you, takes on a job that has to be done. When you need to sneeze you sneeze, this being nature's clever way of getting rid of an annoying object from the nose. The object may be just some dust in the nose which nature is striving to remove.

单选题{{B}}Text 2{{/B}} Overweight has become a problem people all around the world face, and it does not look like it will be solved in the near future regardless of the various efforts from all walks of life. And for those who have a heavier body than they are supposed to, one advice is given repeatedly: eat less and exercise more. This has long been the suggestion for getting rid of those extra pounds. But now it seems that all the hard work may have been in vain. Scientists say there are ten other reasons why people just keep getting bigger. Scientists claim that sleeping habits, central heating, medicines and even some pollutants can play a role in weight gain. Lack of sleep could be partly to blame. In recent years, the average night's sleep has dropped from nine hours to just seven. Sleep lack changes levels of the hormones that regulate food intake and body fat and increase hunger and appetite. If it is too hot or too cold, we burn calories to cool down or heat up. But if the temperature is just right, the calories may be turned into body fat instead. Those who take medicines to control their blood pressure can often put on more weight. Similarly, studies have shown that going on the Pill can add to a woman's weight. Mother Nature may also be to blame, with our body shape being partly determined by our parents. The overweight are also more likely to be associated with partners of a similar size, and their children are more likely to be overweight. The scientists from Yale, Cornell and Johns Hopkins published their analysis of these findings last week. Their reasoning goes like this:1. Sleep--Too little increases appetite.2. Medicine--Many modern medicines lead to us putting on weight.3. Mother's age--Older women are more likely to have obese children.4. Giving up smoking--Nicotine suppresses the appetite.5. Getting older--Weight tends to increase with age.

单选题{{B}}Text 1{{/B}} The predictability of our mortality rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot them- selves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota for each type of death. It just happens that they follow a consistent pattern year after year. A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained oddly static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an intriguing theory called “risk homeostasis”. According to this theory, people instinctively live with a certain level of risk. When something is made safer, people will get around the measure in some way to reassert the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt confers. Other studies have shown that where an intersection is made safer, the accident rate invariably falls there but rises to a compensating level elsewhere along the same stretch of road. It appears, then, that we have an innate need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn't simply a matter of adhering to certain pre cautions—eating the right foods, not smoking, driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.

单选题People have realized that resources are wasted if goods_________.

单选题As my father grew old he became odd. He became mean where once he had been open-handed, and complained about the bills run up by the students who sometimes lived with him. He often woke up at four in the morning and started to go out of the house. And he mislaid things, but he had never in his life had to find anything or file anything. He told the same stories, but he had always repeated stories, absorbed in the telling and unaware of the listener's expression of recognition or boredom. Now he had fewer stories to tell. But the structure of his personality remained intact and his mind was as keen and fresh, as alert to anything new and interesting as it had ever been. The spring before he died I gave a seminar to a group who thought of themselves as avant-guard (先锋派), but he was the most searching questions. In the summer of 1956, after he had to move from the little house in which all the mementos of his life were in place, he was obviously failing. Although his grandchildren found a hotel in which he could live independently and still cause little trouble by leaving his door open or the bath running, because there was someone to watch out for such things, he felt close to the end. When summer school was over, his club, which he had founded and in which he ate lunch every day, closed. He was more alone, but the nephew of an old friend had breakfast with him to be sure that he had one good meal a day, and he himself made a last effort to see those of his old friends who were still alive. He died in his sleep the night he knew I was crossing the Atlantic on my way home. It was my father whose career was limited by the number of his children and his health, who defined for me my place in the world. Although I have acted on a wider stage than either my mother or my father, it is still the same stage—the same world, only with wider dimensions. I have been fortunate in being able to look up to my parents' minds well past my own middle years. And I watched my father grow—he rejected his earlier racial prejudices and came to respect new institutions of the federal government, such as Social Security and public ownership. Watching a parents grow is one of the most reassuring experiences anyone can have, a privilege that comes only to those whose parents live beyond their children' s early adulthood.

单选题There is one difference between the sexes on which virtually every expert and study agree: Men are more aggressive than women. It shows up in two-year-olds. It continues through school days and persists into adulthood. It is even constant across cultures. And there is little doubt that it is rooted in biology--in the male sex hormone testosterone. If there's a feminine trait that's the counterpart of male aggressiveness, it's what social scientists awkwardly refer to as "nurturance". Feminists have argued that the nurturing nature of women is not biological in origin, but rather has been drummed into women by a society that wanted to keep them in the home. But the signs that it is at least partly inborn are too numerous to ignore. Just as tiny infant girls respond more readily to human faces, female toddlers learn much faster than males how to pick up nonverbal cues from others. And grown women are far more adept than men at interpreting facial expressions: A recent study by University of Pennsylvania brain researcher Ruben Gurr showed that they easily read emotions such as anger, sadness and fear. The only such emotion men could pick up was disgust. What difference do such differences make in the real world? Among other things, women appear to be somewhat less competitive--or at least competitive in different ways--than men. At the Harvard Law School, for instance, female students enter with credentials just as outstanding as those of their male peers. But they don't qualify for the prestigious Law Review in proportionate numbers, a fact some school officials attribute to women's discomfort in the incredibly competitive atmosphere. Students of management styles have found fewer differences than they expected between men and women who reach leadership positions, perhaps because many successful women deliberately imitate masculine ways. But an analysis by Purdue social psychologist Alice Eagly of 166 studies of leadership style did find one consistent difference: Men tend to be more "autocratic"--making decisions on their own--while women tend to consult colleagues and subordinates more often. Studies of behavior in small groups turn up oven more differences. Men will typically dominate the discussion, says University of Toronto psychologist Kenneth Dion, spending more time talking and less time listening.
