单选题Forget what Virginia Woolf said about What a writer needs-a room of one's own. The writer she had in mind wasn't at work on a novel in cyberspace, one with multiple hypertexts, animated graphics and downloads of trancey, chiming music. For that you also need graphic interfaces, ReslPlayer and maybe even a computer laboratory at Brown University. That was where Mark Amerika—his legally adopted name; don't ask him about his birth name-composed much of his novel Grammatron. But Grammatron isn't just a story. It's an online narrative (grammatron. com) that uses the capabilities of cyberspace to tie the conventional story line into complicated knots. In the four years it took to produce—it was completed in 1997—each new advance in computer software became another potential story device. "I became sort of dependent on the industry", jokes Amerika, who is also the author of two novels printed on paper." That's unusual for a writer, because if you just write on paper the" technology is pretty stable." Nothing about Grammatron is stable. At its center, if there is one, is Abe Golam, the inventor of Nanoscript, a quasi-mystical computer code that some unmystical corporations are itching to acquire. For much of the story, Abe wanders through Prague-23, a virtual "city" in cyberspace where visitors indulge in fantasy encounters and virtual sex, which can get fairly graphic. The reader wanders too, because most of Grammatron's 1,000-plus text screens contain several passages in hypertext. To reach the next screen, just double-click. But each of those hypertexts is a trapdoor that can plunge you down a different pathway of the story. Choose one and you drop into a corporate- strategy memo, Choose another and there's a XXX- rated sexual rant. The story you read is in some sense the story you make. Amerika teaches digital art at the University of Colorado, where his students develop works that straddle the lines between art, film and literature. "I tell them not to get caught up in mere plot," he says. Some avant-garde writers—Julio Cortazar, Italo Calvino-have also experimented with novels that wander out of their author's control. "But what makes the Net so exciting," says Amerika, "is that you can add sound, randomly generated links, 3-D modeling, animation." That room of one's own is turning into a fun house.

单选题{{B}}16-20{{/B}} President Coolidge's statement, "The business of America is business," still points to an important truth today-- that business institutions have more prestige (威望) in American society than any other kind of organization, including the government. Why do business institutions possess this great prestige? One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected. Competition protects the freedom of the individual by ensuring that there is no monopoly (垄断) of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many businesses compete for the customers' dollar, they cannot afford to treat them like inferiors or slaves. A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, than democracy in preserving freedom. Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic (贵族的) idea of inherited privilege.
