单选题Many people seem to think that science fiction is typified by the covers of some of the old pulp magazines, the Bug-Eyed Monster, embodying every trait and feature that most people find repulsive, is about to grab, and presumably ravish, a sweet, blonde, curvaceous, scantily clad Earth girl. This is unfortunate because it demeans and degrades a worthwhile and even important literary endeavor. In contrast to this unwarranted stereotype, science fiction rarely emphasizes sex, and when it does, it is more discreet than other contemporary fiction. Instead, the basic interest of science fiction lies in the relation between man and his technology and between man and the universe. Science fiction is a literature of change and a literature of the future, and while it would be foolish to claim that science fiction is a major literary genre at this time, the aspects of human life that it considers make it well worth reading and studying for no other literary form does quite the same things. What is science fiction? To begin, the following definition should be helpful: science fiction is a literary subgenre which postulates a change (for human beings) from conditions as we know them and follows the implications of these changes to a conclusion. Although this definition will necessarily be modified and expanded, it covers much of the basic groundwork and provides a point of departure. The first point-that science fiction is a literary subgenre-is a very important one, but one which is often overlooked or ignored in most discussions of science fiction. Specifically, science fiction is either a short story or a novel. There are only a few dramas which could be called science fiction, with Karel Capek's RUR (Rossum's Universal Robots) being the only one that is well known, the body of poetry that might be labeled science fiction is only slightly larger. To say that science fiction is a subgenre of prose fiction is to say that it has all the basic characteristics and serves the same basic functions in much the same way as prose fiction in general, that is, it shares a great deal with all other novels and short stories. Everything that can be said about prose fiction, in general, applies to science fiction. Every piece of science fiction, whether short story or novel, must have a narrator, a story, a plot, a setting, characters, language, and theme. And like any prose, the themes of science fiction are concerned with interpreting man's nature and experience in relation to the world around him. Themes in science fiction are constructed and presented in exactly the same ways that themes are dealt with in any other kind of fiction. They are the result of a particular combination of narrator, story, plot, character, setting, and language. In short, the reasons for reading and enjoying science fiction, and the ways of studying and analyzing it, are basically the same as they would be for any other story or novel.

单选题A very strange old man used to live in our town. He didn't do anything as the rest of people did. He lived alone and didn't talk to anybody. He liked to walk in the woods where there were no roads, following the narrow paths made by animals. People were afraid of him. They thought he was crazy and might do something terrible, like hurting one of the children. One day a little boy disappeared. His parents looked for him for hours, and finally the whole town started a search of the woods. Some people thought the strange old man had taken the child away. Several hours later, the boy was found, very cold and hungry, and it was the old man, who knew the woods so well, who had found him. After that, he still lived alone and walked in the woods, but no one was afraid of him any more.

单选题{{B}}Passage Four{{/B}} Benjamin Day was only 22 years old when he developed the idea of a newspaper for the masses and launched his New York Sun in 1833, which would profoundly alter journalism by his new approach. Yet, several conditions had to exist before a mass press could come into existence. It was impossible to launch a mass-appeal newspaper without invention of a printing press able to produce extremely cheap newspaper affordable almost to everyone. The second element that led to the growth of the mass newspaper was the increased level of literacy in the population. The then increased emphasis on education led to a concurrent growth of literacy as many people in the middle and lower economic groups acquired reading skills. The trend toward "democratization" of business and politics fostered the creation of a mass audience responsive to a mass press. Having seen.others fail in their attempts to market a mass-appeal newspaper, he forged ahead with his New York Sun, which would be a daily and sell for a penny, as compared to the other dailies that went for six cents a copy. Local happenings, sex, violence, features, and human- interest stories would constitute his content. Conspicuously absent were the dull political debates that still characterized many of the six-cent papers. Within six months the Sun achieved a circulation of approximately 8000 issues, far ahead of its nearest competitor. Day's gamble had paid off, and the penny press was launched. James Gordon Bennett, perhaps the most significant and certainly the most colorful of the individuals imitating Day's paper, launched his New York Herald in 1835, even more of a rapid success than the Sun. Part of Bennett's success can be attributed to his skillful reporting of crime news, the institution of a financial page, sports reporting, and an aggressive editorial policy. He looked upon himself a reformer, and wrote in one of his editorials: "I go for a general reformation of morals... I mean to begin a new movement in the progress of civilization." Horace Greeley was another important pioneer of the era. He launched his New York Tribune in 1841 and would rank third behind the Sun and Herald in daily circulation, but his weekly edition was circulated nationally and proved to be a great success. Greeley's Tribune was not as sensational as its competitors. He used his editorial page for crusades and causes. He opposed capital punishment, alcohol, gambling and tobacco. Greeley also favored women's rights. Greeley never talked down to the mass audience and attracted his readers by appealing to their intellect more than to their emotions. The last of the major newspapers of the penny-press era began in 1851. The New York Times, edited by Henry Raymond, promised to be less sensational than the Sun or the Herald and less impassioned than Greeley. The paper soon established a reputation for objective and reasoned journalism. Raymond stressed the gathering of foreign news and served as foreign correspondent himself in 1859. The Times circulation reached more than 40000 before the Civil

单选题Believe it or not, optical illusion (错觉) can cut highway crashes (撞毁). Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent strips, called chevrons (人字形), painted on the roads make drivers think that they are faster than they really are, and thus drivers slow down. Now the American Automobile Association Foundation for Traffic Safety in Washington D. C. is planning to repeat Japan"s success. Starting next year, the Foundation will paint chevrons and other patterns of strips on selected roads around the country to test how well the patterns reduce highway crashes. Excessive speed plays a major role in as much as one fifth of all fatal (致命) traffic accidents, according to the Foundation. To help reduce those accidents, the Foundation will carry its tests in areas where speed-related hazards (危险) are the greatest—curves (弯), exit slopes, traffic circles, and bridges. Some studies suggest that straight, horizontal bars (水平障碍物)painted across roads can initially (最初) cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars. Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are, but also make a lane (车道) appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.

单选题From what Mr. Collins said, we can know that he ______.

单选题 It is not unusual for chief executives to collect millions of dollars a year in pay, stock options, and bonuses. In the last fifteen years, while executive remuneration rose, taxes in the highest income bracket went down. Millionaires are now commonplace. Amiability is not a prerequisite for rising to the top, and there are a number of chief executive officers with legendary bad tempers. It is not the boss's job to worry about the well-being of his subordinates although the man with many enemies will be swept out more quickly in hard times; it is the company he worries about His business savvy is supposed to be based on intimate knowledge of his company and the industry so he goes home nightly with a full briefcase. At the very top--and on the way up--executives are exceedingly dedicated. The American executive must be capable of enough small talk to get him through the social part of his schedule, but he is probably not a highly cultured individual or an intellectual. Although his wife may be on the board of the symphony or opera, he himself has little time for such pursuits. His reading may largely concern business and management, despite interests in other fields. Golf provides him with a sportive outlet that combines with some useful socializing. These days, he probably attempts some form of aerobic exercise to "keep the old heart in shape" and for the same reason goes easy on butter and alcohol, and substances thought to contribute to taking highly stressed executives out of the running. But his doctor's admonition to "take it easy" falls on deaf ears. He likes to work. He knows there are younger men nipping at his heels. Corporate head-hunting, carded on by "executive search firms", is a growing industry. America has great faith in individual talent, and dynamic and aggressive executives are so in demand that companies regularly raid each other's managerial ranks.
