单选题As soon as it was revealed that a reporter for progressive magazine had discovered bow to make a hydrogen bomb, a group of firearm(火器) fans formed the National Hydrogen Bomb Association, and they are now lobbying against any legislation to stop Americans from owning one. "The Constitution," said the associationes spokesman, "gives everyone the right to own arms. It doesn't spell out what kind of arms. But since anyone can now make a hydmgen bomb, the public should be able to buy it to protect theraselves." "Don't you think it's dangerous to have one in the house, particularly where there are children around?" "The National Hydrogen Bomb Association hopes to educate people in the safe handling of this type of weapon. We are instrueting owners to keep the bomb in a locked cabinet and the fuse(导火索) separately in a drawer." "Some people consider the hydrogen bomb a very fatal weapon which could kill somebody." The spokesman said, "Hydrogen bombs don't kill people--people kill people. The bomb is for selfpro-tection and it also has a deterrent effect. If somebody knows you have a nuelear weapon in your house, they're going to think twice about breaking in." "But those who want to ban the bomb for American citizens claim that if you have one locked in the cabinet, with the fuse in a drawer, you would never be able to assemble it in time to stop an intruder(侵入者)." "Another argument against allowing people to own a bomb is that at the moment it is very expensive to build one So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns./

单选题{{B}}Passage Four{{/B}} An Ohio State University study has linked behavior in young children with the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people tended to have offspring with relatively low levels of behavior problems. The opposite held true when the jobs were routine, closely supervised, and dealt with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has positive consequences for her children's behavior," indicates associate professor of sociology Elizabeth Menaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book-keeping, food service, and assembly line positions. Women who are supervised closely at work and made to follow strict orders may be more likely to use this same style in raising their kids. They may emphasize obedience to parental authority and the potential for physical punishment. "We believe that the choice of such a parenting style may increase the frequency of behavior problems in children." On the other hand, mothers whose jobs are less controlled by supervisors and who must work closely with other people probably rely less on physical punishment, instead encouraging children to think about consequences of their actions and take responsibility for their behavior. Such an approach encourages youngsters to follow parental demands even when they aren't being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don't involve constant supervision "develop problem-solving skills that they can bring to other parts of their life". The research also found that those who have more challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, in turn, is linked to fewer behavior problems.

单选题 As people continue to grow and age, our body systems continue to change. At a certain point in your life your body systems will begin to weaken. Your joints may become stiff. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this process that leads us toward the end of our lives. Many factors contribute to your health. A well-balanced diet plays an important role. The amount and type of exercise you get is another factor. Your living environment and the amount of stress you are under is yet another. But scientists studying senescence (衰老) want to know: Why do people grow old? They hope that by examining the aging process on a cellular level medical science may be able to extend the length of life.

单选题Saleswoman: Is there anything else?Customer: ______

单选题A little girl was given so many picture books on her seventh birthday that her father thought his daughter should give one or two of her new books to a little neighbor boy named Robert. Now, taking books, or anything else, from a little girl is like taking candy from a baby, but the father of the little girl had his way and Robert got two of her books. "After all, that leaves you with nine," said the father, who thought he was a philosopher and a child psychologist (心理学家), and couldn't shut his big stupid mouth on the subject. A few weeks later, the father went to his library to look up "father" in the Oxford English Dictionary, to feast his eyes on (一饱眼福) the praise of fatherhood through the centuries, but he couldn't find volume F-G and then he discovered that three others were missing, too--A-B. L-M, V-Z. He began to search his household, and learned what had happened to the four missing volumes. "A man came to the door this morning," said his little daughter, "and he didn't know how to get from here to Torrington, or from Torrington to Winsted, and he was a nice man, much nicer than Robert, and so I gave him four of your books. After all, there are thirteen volumes in the Oxford English Dictionary, and that leaves you with nine. /

单选题Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands whose orbits put them on a collision course with Earth. Buy $ 40 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap. Is it worth it? Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400000 years. Sounds pretty rare—but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It's that simple. " The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New York Times article.

单选题Not too many decades ago it seemed "obvious" both to the general public and to sociologists that modern society has changed people's natural relations, loosened their responsibilities to kin (亲戚) and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the "obviousness" is not true. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else. Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than are big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different style of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers. These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young troublemakers. Moreover, as Wirth suggested, there may be a link between a community's population size and its social heterogeneity (多样性). For instance, sociologists have found much evidence that the size of a community is associated with bad behavior including gambling, drugs, etc. Large-city urbanites are also more likely than their small-town counterparts to have a cosmopolitan (见多识广者的) outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so-called undesirables. Everything considered, heterogeneity and unusual behavior seem to be outcomes of large population size.

单选题Text 4 As a wise man once said, we are all ultimately alone. But an increasing number of Europeans are choosing to be so at an ever earlier age. This isn't the stuff of gloomy philosophical contemplations, but a fact of Europe's new economic landscape, embraced by sociologists, realestate developers and ad executives alike. The shift away from family life to solo lifestyle, observes a French sociologist, is part of the "irresistible momentum of individualism" over the last century. The communications revolution, the shift from a business culture of stability to one of mobility and the mass entry of women into the workforce have greatly wreaked havoc on Europeans private lives. Europe's new economic climate has largely fostered the trend toward independence. The current generation of home-aloners came of age during Europe's shift from social democracy to the sharper, more individualistic climate of American-style capitalism. Raised in an era of privatization and increased consumer choice, today's tech-savvy workers have embraced a free market in love as well as economics. Modern Europeans are rich enough to afford to live alone, and temperamentally independent enough to want to do so. Once upon a time, people who lived alone tended to be those on either side of marriage twenty something professionals or widowed senior citizens. While pensioners, particularly elderly women, make up a large proportion of those living alone, the newest crop of singles are high earners in their 30s and 40s who increasingly view living alone as a lifestyle choice. Living alone was conceived to be negative—dark and cold, while being together suggested warmth and light. But then came along the idea of singles. They were young, beautiful, strong! Now, young people want to live alone. The booming economy means people are working harder than ever. And that doesn't leave much room for relationships. Pimpi Arroyo, a 35-year-old composer who lives alone in a house in Paris, says he hasn't got time to get lonely because he has too much work. "I have deadlines which would make life with someone else fairly difficult." Only an Ideal Woman would make him change his lifestyle, he says. Kaufmann, author of a recent book called "The Single Woman and Prince Chaming—, thinks this fierce new individualism means that people expect more and more of mates, so relationships don't last long—if they start at all. Eppendorf, a blond Berliner with a deep tan, teaches grade school in the mornings. In the afternoon she sunbathes or sleeps, resting up for going dancing. Just shy of 50, she says she'd never have wanted to do what her mother did—give up a career to raise a family. Instead, "I've always done what I wanted to do: live a serf-determined life/

单选题Regular child care provided outside home or by someone other than the mother does not in itself undermine(削弱) healthy emotional connections between mothers and their 15-month-old infants, according to a long-term national study. The finding holds even if care begins during the first 3 months after birth and runs for 30 hours or more per week. Among infants who receive unkind and unresponsive care from their mothers, however, the mother-child relationship may be damaged. "This research helps us put apart complexities regarding child care that have not previously been studied in detail." contends Jay Belsky, a psychologist at Pennsylvania State University. Belsky and several of his colleagues announced their findings last week at the international conference. The investigation consists of 1 153 children and their families living in or near Boston. The youngsters, no more than 1 month old when they entered the study in 1991, will be tracked until the age of 7. Experimenters administered questionnaires to mothers in their homes and videotaped baby caretakers interacting with the kids at ages 1, 6, and 15 months. Independent observers rated the quality of each child care efforts and noted infant nervousness. Unlike most previous studies, this one allows researchers to observe each caretaker's personality at child nursing, and kids' emotional reaction by the equipment. After taking family factors into account, other psychologists state that the researchers found no relation between the quality of child care and infants' response. But the experimenters contend that the boys who spent more than 30 hours per week in child care exhibited more emotion for their mothers than other boys who didn't, and the girls who spent the same hours per week in child care showed a modest rise in this emotion. Therefore, quality of child care outside home plays an important role in the connection between mothers and infants.
