单选题Sound moves from its source to the ear by wave like fluctuations in air pressure, something like the peaks and troughs or the lowest point of ocean waves. One way to keep from hearing sound is to use ear plugs. Another way is to cancel out the sound with anti-sound. Using a noise maker controlled by a microprocessor, engineers have produced sound waves that are half a wavelength out of phase with those of the noise to be quieted--each peak is matched to a trough, and vice versa. Once the researchers have recorded the offending sound, a microprocessor calculates the amplitude and wavelength of sound that will cancel out the highest and lowest points of the noise. It then produces an electric current that is amplified and fed to a loudspeaker, which produces anti-sound and wipes out the noise. If the anti-sound goes out of synchronization, a microphone picks up the leftover sound and sends it back to the microprocessor, which changes the phase of the anti-sound just enough to cause complete silence. The research team has concentrated on eliminating low-frequency noise from ship engines, which causes fatigue that can impair the efficiency and alertness of the crew, and may mask the warning sounds of alarm and fog signals.

单选题Crossing Wesleyan University's campus usually requires walking over colorful messages chalked on the ground. They can be as innocent as meeting announcements, but in a growing number of cases the language is meant to shock. It's not uncommon, for instance, to see lewd reference to professors' sexual preferences scrawled across a path or the mention of the word "Nig" that African-American students say make them feel uncomfortable. In resp0nse, officials and students at schools are now debating ways to lead their communities away from forms of expression that offend or harass. In the process, they're putting up against the difficulties of regulating speech at institutions that pride themselves on fostering open debate. Mr. Bennet of Wesleyan says he had gotten used to seeing occasional chalkings filled with four-letter words. Campus tradition made any horizontal surface not attached to a building a potential billboard. But when chalkings began taking on a more threatening and obscene tone, Bennet deeided to act. "This is not acceptable in a workplace and not acceptable in an institution of higher learning," Bennet says. For now, Bennet is seeking input about what kind of message-posting policy the school should adopt. The student assembly recently passed a resolution saying the "right to speech comes with implicit responsibilities to respect community standards". Other public universities have confronted problems this year while considering various ways of regulating where students can express themselves. At Harvard Law School, the recent controversy was more linked to the academic setting. Minority students there are seeking to curb what they consider harassing speech in the wake of a series of incidents last spring. At a meeting held by the "Committee on Health Diversity" last week, the school's Black Law Students Association endorsed a policy targeting discriminatory harassment. It would trigger a review by school officials if there were charges of "severe or pervasive conduct" by students or faculty. The policy would cover harassment based on, but not limited to, factors such as race, religion, creed, sexual orientation, national origin, and ethnicity. Boston attorney Harvey Silverglate, says other schools have adopted similar harassment policies that are actually speech codes, punishing students for raising certain ideas. "Restricting students from saying anything that would be perceived ns very unpleasant by another student continues uninterrupted," says Silverglate, who attended the Harvard Law Town Meeting last week.

单选题The most thoroughly studied intellectuals in the history of the New World are the ministers and political leaders of seventeenth-century New England. According to the standard history of American philosophy, nowhere else in colonial America was "so much important attached to intellectual pursuits". According to many books and articles, New England"s leaders established the basic themes and preoccupations of an unfolding, dominant Puritan tradition in American intellectual life. To take this approach to the New Englanders normally means to start with the Puritans" theological innovations and their distinctive ideas about the church—important subjects that we may not neglect. But in keeping with our examination of southern intellectual life, we may consider the original Puritans as carriers of European culture, adjusting to New World circumstances. The New England colonies were the scenes of important episodes in the pursuit of widely understood ideals of civility and virtuosity. The early settlers of Massachusetts Bay included men of impressive education and influence in England. Besides the ninety or so learned ministers who came to Massachusetts churches in the decade after 1629, there were political leaders like John Winthrop, an educated gentleman, lawyer, and official of the Crown before he journeyed to Boston. There men wrote and published extensively, reaching both New World and Old World audiences, and giving New England an atmosphere of intellectual earnestness. We should not forget, however, that most New Englanders were less well educated. While few crafts men or farmers, let alone dependents and servants, left literary compositions to be analyzed. Their thinking often had a traditional superstitions quality. A tailor named John Dane, who emigrated in the late 1630s, left an account of his reasons for leaving England that is filled with signs. Sexual confusion, economic frustrations, and religious hope—all name together in a decisive moment when he opened the Bible, told his father the first line he saw would settle his fate, and read the magical words: "come out from among them, touch no unclean thing, and I will be your God and you shall be my people." One wonders what Dane thought of the careful sermons explaining the Bible that he heard in puritan churched. Meanwhile, many settles had slighter religious commitments than Dane"s, as one clergyman learned in confronting folk along the coast who mocked that they had not come to the New World for religion. "Our main end was to catch fish."

The single business of Henry Thoreau, during forty-odd years of eager activity, was to discover all economy calculated to provide a satisfying life. His one concern, which gave to his ramblings in Concord fields a value of high adventure, was to explore the true meaning of wealth. As he understood the problems of economics, there were three possible solutions open to him, to exploit himself, to exploit his fellows, or to reduce the problem to its lowest denominator. The first was quite impossible--to imprison oneself in a treadmill when the morning called to great adventure. To exploit one's fellows seemed to Thoreau's sensitive social conscience an even greater infidelity. Freedom with abstinence seemed to him better than serfdom with material well-being, and he was content to move to Walden Pond and set about the high business of living, "to front only the essential facts of life and to see what it had to teach." He did not advocate that other men should build cabins and live isolated. He had no wish to dogmatize concernig the best mode of living--each must settle that for himself. But that a satisfying life should be lived, he was virtually concerned. The story of his emancipation from the lower economics is the one romance of his life, and Walden is his great book. It is a book in praise of life rather than of Nature, a record of calculating economies that studied saving in order to spend more largely. But it is a book of social criticism as well, in spite of its explicit denial of such a purpose. In considering the true nature of economy he concluded, with Ruskin, that the cost of a thing is the amount of life which is required in exchange for it, immediatey or in the long run. In Walden Thoreau elaborated the text: "The only wealth is life."
