单选题Many teachers believe that the responsibility for learning lies with the students. If a long reading assignment is given, teachers expect students to be familiar with the information in the reading even if they do not discuss it in class or give an examination. The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades. When research is assigned, the professor in the United States expects the students to take the initiative and complete the assignment with less guidance. Professors will help students who need it, but prefer that their students not be over-dependent on them. In the united States, professors have other duties besides teaching. Often they are responsible for administrative work within their departments. In addition, they may be obliged to publish articles and books. Therefore the time that a professor can spend with a student outside of class is limited. If a student has problems with classroom work, the student should either approach a professor during office hours or make appointment. Participation in the classroom is not only accepted but also expected of the students in many courses. Some professors base part of the final grade on the students oral participation. Although there are formal lectures during which the student has a passive role (i.e. listening and taking notes), many courses are organized around classroom discussions, student questions and informal lectures. In the teaching of science and mathematics, the dominant mode of instruction is generally traditional with teachers presenting formal lectures and students taking note. However, new educational trends have psychology classes, for example, are often required to solve problems in groups, design projects, make presentations and examine case studies. Since some college or university courses are applied rather than theoretical they stress doing and involvement. 1. When research is assigned the professor ______.

单选题. (英语专业必做) Drunken driving—sometimes called America's socially accepted form of murder—has become a national epidemic. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past decade. Heavy drinking used to be an acceptable part of the American macho (男子汉) image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving your children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18—20-year-old drivers more than doubled, so the state recently upped it back to 21. Reformers, however, tear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop "responsible attitude" about drinking and teach them to resist peer pleasure to drink. New laws have led to increased arrests and tests in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks. A tavern (酒栈) in Massachusetts was fined for serving six or more brandies to a customer who was "obviously intoxicated" and later drove off the road, killing a nine-year-old boy. As the fatalities continue to occur daily in every state, some Americans are even beginning to think well of the 13 years of national prohibition of alcohol that began in 1919, which President Hoover called the "noble experiment". They forgot that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the becoming drug trade, there is no easy solution.6. Drunken driving has become a serious problem in America because ______.

单选题. The factors that acid up to a happy life for most people are not what we typically hear about. Things like earning a master's degree don't make people happy over an extended period of time. Rather, the key to happiness, and the difference between happy and unhappy Americans, is a life that reflects values and practices like hard work, marriage, charity, and freedom. Work When more than 1,000 people across the country were asked in 2002, "If you were to get enough money to live comfortably for the rest of your life, would you stop working?" fewer than a third of the Americans answered yes. Contrary to widely held opinion, most Americans like or even love their work. In 2002 an amazing 89 percent of workers said they were very satisfied or somewhat satisfied with their jobs. This isn't true just for those with high-paying, highly skilled jobs but for all workers across the country. And the percentage is almost exactly the same among those with and without college degrees and among those working for private companies, nonprofit organizations, and the government. For most Americans, job satisfaction is nearly equivalent to life satisfaction. Among those people who say they are very happy in their lives, 95 percent are also satisfied with their jobs. Furthermore, job satisfaction would seem to be causing overall happiness, not the other way around. Marriage Family In 2004, 42 percent of married Americans said they were very happy. Just 23 percent of never-married people said this. Overall, married people were six times more likely to say that they were very happy than to report that they were not too happy. And generally speaking, married women say they're happy more often than married men. Marriage isn't just associated with happiness—it brings happiness, at least for a lot of us. One 2003 study that followed 24,000 people for more than a decade documented a significant increase in happiness alter people married. For some, the happiness increase wore off in a few years, and they ended up back at their premarriage happiness levels. But for others, it lasted as long as a lifetime. What about having kids? While children, on their own, don't appear to raise the happiness level (they actually tend to slightly lower the happiness of a marriage), studies suggest that children are almost always part of an overall lifestyle of happiness, which is likely to include such things as marriage and religion. Charity We've all heard that money doesn't buy happiness, and that's certainly true. But there is one way to get it: Give money away. The evidence is clear that gifts to charitable organizations and other worthy causes bring substantial life satisfaction to the givers. If you want $50 in authentic happiness today, just donate it to a favorite charity. People who give money to charity are 43 percent more likely than nongivers to say they're very happy. Volunteers are 42 percent more likely to be very happy than nonvolunteers. It doesn't matter whether the gifts of money go to churches or concerts; religious giving and unreligious giving leave people equally happy, and far happier than people who don't give. Even donating blood, an especially personal kind of giving, improves our attitude. Fundamentally, the more people give, the happier they get. Freedom In fact, freedom and happiness are intimately related: People who consider themselves free are a lot happier than those who don't. In 2000 the General Social Survey revealed that people who personally feel "completely free" or "very free" were twice as likely as those who don't to say they're very happy about their lives. Not all types of freedom are the same in terms of happiness, however. Researchers have shown that economic freedom brings happiness, as does political and religious freedom. On the other hand, moral freedom—a lack of constraints on behavior—does not. People who feel they have unlimited moral choices in their lives when it comes to matters of sex or drugs, for example, tend to be unhappier than those who do not feel they have so many choices in life. Lessons for America The data tell us that what matters most for happiness is not having a lot of things but having healthy values. Without these values, our jobs and our economy will bring us joyless riches. The facts can help remind us of what we should be paying attention to, as individuals and as families, if we want to be happy. Our happiness is simply too important to us—and to America—to do anything less.1. What will probably bring about overall happiness? ______
