单选题The United States is well known for its network of major highways designed to help a driver get from one place to another in the shortest and possible time. 1 these wide modern roads are generally 2 many well maintained, with 3 sharp curves and many straight 4 , a direct route is not always the most 5 one. Large highways often pass 6 scenic areas and interesting small towns. Furthermore, these highways generally 7 large urban centers, which means that they became crowded with 8 traffic during rush hours, 9 the "fast, direct" route becomes a very slow route. However, there is 10 always another route to take 11 you are not in a hurry. Not far from the 12 new "superhighways" there are often older 13 of heavily traveled roads which go through the countryside. 14 these are good two-lane(双重音) roads; others are uneven roads 15 through the country. These secondary routes may go up steep slopes, along high 16 , or down frightening hillsides to towns 17 in deep valleys. Through these less direct routes, longer and slower, they generally go to places 18 the air is clean and the scenery is beautiful, and the driver may have a 19 to get a fresh, clean 20 of the world.

单选题Futurists love computers. After all,40 years ago electronic digital computers didn't exist; today microchips as tiny as a baby's fingernail are making all sorts of tasks faster and easier. Surely the future holds still more miracles. Some of the computer experiments now going on inspire exciting visions of the future. For example, scientists are working on devices that can electronically perform some sight and hearing functions, which could make life easier for the blind and deaf. They're also working on artificial arms and legs that respond to the electric impulses produced by the human brain. Scientists hope that some day a person who's lost an arm could still have near-normal brain control over an artificial arm. Video games, computerized special effects in movies, and real-life training machines now being used by the US Army are causing some people to predict new educational uses for computers. Computers could some day be used to simulate travel to other planets, to explore the ocean floor, or to look inside an atom. Experiments with electronic banking and shopping inspire predictions that these activities will soon be done from home computer terminals. Cars, too, might be equipped with computers to help drivers find their way around (Honda has one in an experimental car) or to communicate with home and office computers. Many people, including handicapped workers with limited ability to move around, already are working at home using computer terminals. Each terminal is connected to a system at a company's main office. Some futurists say the day may come when few people will have to leave home to go to work -- they'll just turn on a terminal A growing number of factories such as the General Motors Plant in Newark, Delaware, "hire" computerized robots to perform tasks such as spot welding. Some executives get a gleam in their eyes as they envision the spread of these "perfect workers" -- no coffee breaks, no strikes, and no vacations or sick days. These modern and potential computer uses are possible because of the silicon microchip. These chips, which have become increasingly complex since their beginning in 1959, contain a network of information pathways. Electronic impulses travel along the paths. The plans for a chip look much like a city street plan and can be as large as a football field. It can take as long as three months to complete a new chip design. Chips are used to store information, too. An entire "computer" can be put onto one chip -- called a microprocessor. As chips become even more complex, easier to make, and less costly, futurists predict limitless possibilities. A group of Japanese scientists is working on a new generation of computers, which they hope will be able to understand vocal instructions, talk back to their users, and automatically try out alternate solutions to a problem to come up with the best answer. Some people say that the humans of the future will never be without their companion -- computers. Predicting the future can be tricky, of course. In 1948 an IBM study predicted that there would never be enough demand for computers to justify going into the business!

单选题A person may have an idea about himself that will prevent him from doing good work. He may have the idea that he is not capable of it. A child may think he is stupid because he does not understand how to make the most of his mental faculties or he may accept another person"s mistaken estimate of his ability. Older people may be handicapped by the mistaken belief that they are incapable of learning anything new because of their age. A person who believes that he is incapable will not make a real effort, because he feels that it would be useless. He won"t go at a job without the confidence necessary for success. He is therefore likely to fail, and the failure will strengthen his belief in his incompetence. Alfred Adler, a famous doctor, had an experience which illustrates this. When he was a small boy, he got off to a poor start in arithmetic. His teacher got the idea that he had no ability in arithmetic, and told his parents what she thought in order that they would not expect too much of him. In this way, they too developed the idea, "Isn"t it too bad that Alfred can"t do arithmetic?" He accepted their mistaken estimate of his ability, felt that it was useless to try, and was very poor at arithmetic, just as they expected. One day, Adler succeeded in solving a problem which none of the other students had been able to solve. This gave him confidence. He rejected the idea that he couldn"t do arithmetic and was determined to show them that he could. His newly found confidence stimulated him to go at arithmetic problems with a new spirit. He now worked with interest, determination and purpose, and he soon became extraordinarily good at arithmetic. This experience made him realize that many people have more ability than they think they have, and that lack of success is as often the result of lack of knowledge of how to apply one"s ability, lack of confidence and lack of determination as it is the result of lack of ability.

单选题How did the woman know about the Student Action Union?

单选题In the seventeenth century, European soldiers who came across some Indian groups in the western Great Lakes found that several native tribes were living in the area without a formal leadership system. They appeared to be "quite friendly with each other without a formal authority!" Not only did the Indians appear to lack a formal system of authority, but they also deeply hated any efforts to control their actions. All members of the tribes knew what was required of them by lifelong familiarity with the tasks of the area. These tasks tended to be simple, since the Indian's rate of social change was slow. Thus, although subgroups such as soldiers had recognized leaders, no real authority was required. Rather than giving direct orders (which were considered rough), members of the tribes would arouse others to action by examples. It would be difficult, if not impossible, to carry out such a system in our own society. Most of us have grown up under one authority or another for as long as we can remember. Our parents, our teachers, our bosses, our government all have the recognized right under certain conditions to tell us what to do. The authority is so much a part of our culture that it is hard for us to imagine a workable society without it. We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale. Of course, the major reason why the Indian system would not be suitable for us is that our society is too large. The number of tasks that various members of our society have to perform often under tight time and resource limitations could not be treated by the Indian system. In modern societies, the formal authority system is necessary to achieve any social objectives.

单选题 Rowena and Billy Wrangler are model high school students. They study hard and do extremely well on achievement tests. And next year, Rowena will be attending Harvard University. Billy, her younger brother, hopes to go to Cornell. What makes Rowena and Billy different from most students is that they don't go to school. In fact, they've never been to school. Since kindergarten, they've studied at home. Neither Rowena nor Billy feels as if they've missed out on anything by being taught at home. Like many of more than one million people who receive home schooling in the United States, they feel as if they've gotten a good education. The home-schooling trend began in the U.S. in the 1980s with parents keeping their children out of public schools so they could provide religious education at home. Today, as the home-schooling trend continues to grow, parents are more likely to consider home schooling as an option because they believe schools don't do a very good job of teaching and are occasionally dangerous places. But can parents really do a better job? The answer in many cases is yes. In many studies, students taught at home ranked, average or above average when compared to students who went to public schools. More importantly, these students were often more self-directed and have a greater depth of knowledge. "They are very well prepared for academic challenges," says Patricia Riordan, the dean of admissions at George Mason University. One such student, Robert Conrad, now a sophomore at university, claims he really learned how to study and schedule his time during his eight years of home schooling. Still, not every student is as successful as Robert. "For every home-schooling success story, there are an equal number of failures," states Henry Lipscomb, an educational researcher. "There are just so many disadvantages that students taught at home have to overcome." For example, they have fewer chances to interact with others of their own age. Consequently, they sometimes lack the usual social skills. "No matter what, though," states Lipscomb, "home-schooling is a growing trend. I think we'll be seeing more and more of this."
