[阅读理解]Passage 1 Upon reaching an appropriate age (usually between 18 and 21 years), children are encouraged, but not forced, to “leave the nest” and begin an independent life. After children leave home they often find social relationship and financial support outside the family. Parents do not arrange marriages for their children, nor do children usually ask permission of their parents to get married. Romantic love is most often the basis for marriage in the United States; young adults meet their future spouses (配偶) through other friends, at jobs, and in organizations and religious institutions. Although children choose their own spouses, they still hope their parents will approve of their choices. In many families, parents feel that children should make major life decisions by themselves. A parent may try to influence a child to follow a particular profession but the child is free to choose another career. Sometimes children do precisely the opposite of what their parents wish in order to assert their independence. A son may deliberately decide not to go into his father’s business because of a fear that he will lose his autonomy in his father’s workplace. This independence from parents is not an indication that parents and children do not love each other. Strong love between parents and children is universal and this is no exception in the American family. Coexisting with such love in the American family are cultural values of self-reliance and independence. 1. The writer discusses the marriage of young adults in order to show that they _____. A. enjoy the freedom of choosing their spouses B. want to win the permission of their parents C. have a strong desire to become independent D. try to challenge the authority of their parents 2. Most young adults in America would get married for the sake of ____. A. love B. financial concern C. their parents D. family background 3. Based on the passage, it can be inferred that _____. A. American young adults are likely to follow the suit of their parents. B. most American parents never make major decisions for their children. C. American young adults possess cultural values of independence. D. when a young adult steps into his twenties, he will leave his home permanently. 4. A son is unwilling to work in his father’s business mainly because he _____. A. wishes to make full use of what he has learnt in school B. wants to prove his independence C. likes to do the opposite of what his parents approve of D. tries to show his love for his parents 5. The subject matter of this passage is _____. A. cultural values in the American family B. marriage arrangements C. young adult’s pursuit of a career D. decision making Passage 2 No country in the world has more daily newspapers than the U.S.A. There are almost 2,000 of them, as compared with 180 in Japan, 144 in Argentina and 111 in Britain. The quality of some American papers is extremely high and their views are quoted all over the world. Distinguished dailies like the Washington Post or the New York Times have a powerful influence all over the country. However the Post and the Times are not national newspapers in the sense that The times is in Britain or Le Monde is in France, since each American city has its own daily newspaper. The best of these present detailed accounts of national and international news, but many tend to limit themselves to state or city news. Like the press in most other countries, American newspapers range from the “sensational”, which feature crime, sex and rumor, to the serious, which focus on factual news and the analysis of world events. But with few exceptions American newspapers try to entertain as well as give information, for they have to compete with television. Just as American newspapers give way to all tastes, so do they also try and apply to readers for all political persuasions. A few newspapers support extremist (过激分子) groups on the far right and on the far left, but most daily newspapers attempt to attract middle-of-the-road Americans who are essentially moderate. Many of these papers print columns by well-known journalists of different political and social views in order to present a balanced picture. As in other democratic countries American newspapers can be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once bravely uncovered political scandals (丑闻) or crimes, for instance, the Watergate Affair. The newspapers drew the attention of the public to the fears of the Vietnam War. 1. There are fewer national newspapers in ______. A. Britain than in the U.S.A. B. France than in Britain C. the U.S.A. than in Britain or France D. France than in the U.S.A. or Britain 2. Most American newspapers try to entertain their readers because ______. A. they have to keep up a good relation with them B. they have to compete with television C. they have to write about crime, sex and rumor D. they have to give factual news in an interesting way 3. Many American newspapers attract readers of different political tendency by ______. A. supporting extremist groups from time to time B. inviting middle-of-the-road Americans to write articles for them C. avoiding carrying articles about extremists D. printing articles representing different political viewpoints 4. In this passage the underlined word “press” (Para.2) means ______. A. a machine for printing B. the business of printing C. great force D. newspapers 5. The passage is mainly about ______. A. the characteristics of American newspapers B. the development of American newspapers C. the functions of American newspapers D. the merits and shortcomings of American newspapers Passage 3 The key to any successful garage sale (家庭旧物出售) is to get the word out. The best means of advertising your sale is to place an ad in the local newspaper. If you have a city and neighborhood paper, make sure you advertise in both. The ad should be large enough that it stands out. It should also include information on where the sale is located with directions, the hot items you're selling and the time the sale will start and end. An ad should be placed at least two days before the sale and run until the day of your event. That way people can plan their route (路线) to the sale in advance. Signs are another great way to inform your community. Post them in places where people gather, such as stores and community centers. Some businesses have a central bulletin board (布告栏), which is the best place to advertise. Other places to post are at the local college or university campus. This is especially helpful if your sale is happening in August or early September when students have returned to school and are looking for cheap finds. Post signs around your neighborhood. You should also place both ads and direction signs, especially if you're located on a side street without a major presence. Signs will attract and direct people. Just make sure you print in bold letters and use large direction signs so people can read the information from the front seat of their car. 1. The best way of getting out the news of your garage sale is to ______. A. publish the news online B. visit people door-to-door C. advertise in the local newspaper D. make phone calls to your neighbors 2. You should place an ad at least two days before the sale so that people can ______. A. get enough cash for the sale B. compare prices of the items C. select the items they will buy D. decide on their route in advance 3. Why should signs be posted in a community center? A. Schools are nearby. B. There are many stores. C. Students often meet there. D. More people gather there. 4. What advice is given for printing the signs according to the last paragraph? A. Colored signs are preferred. B. Bold letters should be used. C. Large pictures should be included. D. Phone numbers should be provided. 5. The best title for the passage might be ______. A.
