下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。第一篇 Eat Healthy “Clean your plate!” and “Be a member of the clean plate club!” Just about every kid in the US has heard this from a parent or grandparent. Often, it’s accompanied by an appeal: “Just think about those starving orphans in Africa!” Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying “clean the plate”, perhaps we should save some food for tomorrow. According to news reports, US restaurants are partly to blame for the growing bellies. A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand. Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this, too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve ‘portions that are too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can’t afford fine dining still prefer large portions. 70 percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $ 25,000 want smaller. It’s not that working class Americans don’t want to eat healthy. It’s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck, happy to save a little money for next year’s Christmas presents. What does the survey indicate

阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 Changes in Museums Museums have changed. They are no longer places that one “should” visit, they are places to enjoy and learn. At a science museum in Ontario, Canada, you can feel your hair stand on end as harmless electricity passes through your body. At the Metropolitan (大城市的) Museum of Art in New York City, you can look at the seventeenth century instruments while listening to their music. At New York’s American Museum of Natural History recently, you can help make a bone-by bone reproduction of the museum’s dinosaur(恐龙), a beast that lived 200 million years ago. More and more museum directors are realizing that people learn best when they can somehow become part of what they are seeing. In many science museums, for example, there are no guided tours. The visitor is encouraged to touch, listen, operate, and experiment so as to discover scientific principles for himself. The purpose is not only to provide fun but also to help people feel at home in the world of science. The theory is that people who do not understand science will probably fear it, and those who fear science will not use it to best advantage. One cause of all these changes is the increase in wealth and leisure time. Another cause is the rising percentage of young people in the population. Many of these young people are college students or college graduates. Leon F. Twiggs, a young black professor of art once said, “They see things in a new and different way. They are not satisfied to stand and look at works of art; they want art they can participate(参加) in.” The same is true of science and history. When visiting museums nowadays, people can take part in many activities.
第三篇 Generation Gap A few years ago, it was fashionable to speak of a generation gap, a division between young people and their elders. Parents complained that children did not show them proper respect and obedience, while children complained that their parents did not understand them at all. What had gone wrong Why had the generation gap suddenly appeared Actually, the generation gap has been around for a long time. Many critics argue that it is built into the fabric of our society. One important cause of the generation gap is the opportunity that young people have to choose their own life styles. In more traditional societies, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and approve of, and often to continue the family occupation. In our society, young people often travel great distances for their education, most out of the family home at an early age, marry or live or choose occupations different from those of their parents. In our upwardly mobile society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do. Often, however, the ambitions that parents have for their children are another cause of the division between them. Often they discover that they have very little in common with each other. Finally, the speed at which changes take place in our society is another cause of the gap between the generations. In a traditional culture, elderly people are valued for their wisdom, hut in our society the knowledge of a lifetime may Become obsolete overnight. The young and the old seem to live in two very different worlds, separated by different skills and abilities. No doubt, the generation gap will continue to be a feature of American life for some time to come. Its causes are rooted in the freedoms and opportunities of our society, and in the rapid pace at which society changes. Which one is NOT the cause of the generation gap
