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."

单选题{{B}}Directions:{{/B}} There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. 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."

单选题The devastating effects of earthquakes on human lives and property have encouraged the search for earthquake prediction. This challenge remains and contemporary seismologists continue to seek reliable methods for pinpointing the time, place and magnitude of individual quakes. One prediction technique involves an analysis of the recurrence rates of earthquakes as indicators of future seismic activity. Earthquakes are concentrated in certain areas of the world where tectonic plates such as the Pacific Plate, the Eurasian Plate and the African Plate meet and create fault zones and it is in these areas that seismologists focus their investigations. The tectonic plate model provides another tool for earthquake prediction by calculating the accumulated strain at plate boundaries. When the strain reaches a certain magnitude the pressure must be released and it is therefore hypothesized that in such eases an earthquake is imminent. The search for premonitory phenomena has received particular attention. In contrast to the ancient Greeks and Romans, who relied on the howling of dogs as a warning sign, modern seismologists have focused on physical evidence for an impending earthquake. Evidence of plate strain can be found by measuring relative movements in geodetic stations, while chemical changes also offer signals for seismologists. Using chemical-detection techniques, scientists established a link between the rise in the concentration of radon gas in mineral water and the subsequent earthquake. Analysis of the changes in magnetic properties and conductivity of rocks provides further data for prediction. The electrical and magnetic properties of crustal rocks particularly sensitive to strain and studies measuring changes which occur in these properties have provided promising results. The conductivity of crustal rock is determined by the degree to which the rock is saturated with fluid and the electrolytic properties of those fluids. Before large earthquakes, small fractures develop in rocks, which change the quantity of fluid present. These changes can be measured and provide useful predictive data. However, similar changes in the fluid-bearing capacity of rock can occur as a result of other factors such as changes in the water table, and therefore this technique is not entirely reliable. The belief that the behavior of birds, eats and dogs provides evidence of imminent earthquakes has recently gained credence. It is hypothesized that the animals are sensitive to the seismic waves which precede major quakes. In zones where earthquakes are known to occur, improved construction techniques can significantly reduce the effects of seismic waves. If more accurate information regarding the time and magnitude were available, governments could take even more effective measures to reduce the impact on human life. If an entirely accurate prediction technique became available, there would be significant social and political implications. An earthquake prediction in a major urban area would require governments to provide an effective evacuation strategy, necessitating massive resource and political will.

单选题Whenever the political laws of the United States are to be discussed, it is with the doctrine of the sovereignty of the people that we must begin. The principle of the sovereignty of the people, which is always to be found, more or less, at the bottom of almost all human institutions, generally remains there concealed from view. It is obeyed without being recognized, or if for a moment it is brought to light, it is hastily cast back into the gloom of the sanctuary. "The will of the nation" is one of those phrases, that have been most largely abused by the wily and the despotic of every age. Some have seen the expression of it in the purchased suffrages of a few of the satellites of power; others, in the votes of a timid or an interested minority; and some have even discovered it in the silence of a people, on the supposition that the fact of submission established the right to command. In America the principle of the sovereignty of the people is neither barren nor concealed, as it is with some other nations; it is recognized by the customs and proclaimed by the laws; it spreads freely, and arrives without impediment at its most remote consequences. If there is a country in the world where the doctrine of the sovereignty of the people can be fairly appreciated, where it can be studied in its application to the affairs of society, and where its dangers and its advantages may be judged, that country is assuredly America. It has been observed that, from their origin, the sovereignty of the people was the fundamental principle of most of the British colonies in America. It was far, however, from then exercising as much influence on the government of society as it now does. Two obstacles, the one external, the other internal, checked its invasive progress. It could not ostensibly disclose itself in the laws of colonies which were still forced to obey the mother country, it was therefore obliged to rule secretly in the provincial assemblies, and especially in the townships. American society at that time was not yet prepared to adopt it with all its consequences. Intelligence in New England and wealth tended to keep the exercise of social power in the hands of a few. Not all the public functionaries were chosen by popular vote, nor were all the citizens voters. The electoral franchise was everywhere somewhat restricted and made dependent on a certain qualification. Which was very low in the North and more considerable in the South. The American Revolution broke out, and the doctrine of the sovereignty of the people came out of the townships and took possession of the state. Every class was enlisted in its cause; battles were fought and victories obtained for it; it became the law of the laws.
