单选题Researchers have studied the poor as individuals, as families and households, as members of poor communities, neighborhoods and regions, as products of larger poverty-creating structures. They have been analyzed as victims of crime and criminals, as members of minority cultures, as passive consumers of mass culture and active producers of a "counterculture", as an economic burden and as a reserve army of labor——to mention just some of the preoccupations of poverty research. The elites, who occupy the small upper stratum within the category of the non-poor, and their functions in the emergence and reproduction of poverty are as interesting and important an object for poverty research as the poor themselves. The elites have images of the poor and of' poverty which shape their decisions and actions. So far, little is known about those images, except as they are sketchily portrayed in popular stereotypes. The elites may well ignore or deny the external effects of their own actions(and omissions) upon the living conditions of the poor. Many social scientists may take a very different view. As poverty emerged and was reproduced, legal frameworks were created to contain the problems it caused with profound, and largely unknown, consequences for the poor themselves. In general, political, educational and social institutions tend to ignore or even damage the interests of the poor. In constructing a physical infrastructure for transport, industry, trade and tourism, the settlements of the poor are often the first to suffer or to be left standing and exposed to pollution, noise and crowding. Most important are the economic functions of poverty, as for lack of other options the poor are forced to perform activities considered degrading or unclean. The poor are more likely to buy second-hand goods and leftover foodstuffs, thus prolonging their economic utility. They are likely to use the services of low-quality doctors, teachers and lawyers whom the non-poor shy away from. Poverty and the poor serve an important symbolic function, in reminding citizens of the lot that may befall those who do not heed the values of thrift, diligence and cleanliness, and of the constant threat that the rough, the immoral and the violent represent for the rest of society. Physically, the poor and the non-poor are kept apart, through differential land use and ghettoization. Socially, they are separated through differential participation in the labor market, the consumption economy, and in political, social and cultural institutions. Conceptually, they are divided through stereo- typing and media cliche. This separation is even more pronounced between the elites and the poor.

单选题Wall Street in a conceptual sense represents financial and economic power. To Americans, it can sometimes represent elitism and power politics, and its role has been a source of controversy throughout the nation"s history, particularly beginning around the Gilded Age period in the late 19th century. Wall Street became the symbol of a country and economic system that many Americans saw as having developed through trade, capitalism, and innovation. Wall Street has become synonymous with financial interests, often used negatively. During the mortgage mess from 2007—2010, Wall Street financing was blamed as one of the causes, although most commentators blame an interplay of factors. The U. S. government with the Troubled Asset Relief Program bailed out the banks and financial backers with billions of taxpayer dollars, but the bailout was often criticized as politically motivated, and was criticized by journalists as well as the public. One writer in the Huffington Post looked at FBI statistics on robbery, fraud, and crime and concluded that Wall Street was the "most dangerous neighborhood in the United States" if one factored in the $ 50 billion fraud perpetrated by Bernie Madoff. Many complained that the resulting Sarbanes-Oxley legislation dampened the business climate. Interest groups seeking favor with Washington lawmakers, such as car dealers, have often sought to portray their interests as allied with Main Street rather than Wall Street. When the United States Treasury bailed out large financial firms, to ostensibly halt a downward spiral in the nation"s economy, there was tremendous negative political fallout, particularly when reports came out that monies supposed to be used to ease credit restrictions were being used to pay bonuses to highly-paid employees. Analyst William Cohan argued that it was "obscene(肮脏的)" how Wall Street reaped "massive profits and bonuses in 2009" after being saved by "trillions of dollars of American taxpayers" treasure" despite Wall Street"s "greed and irresponsible risk-taking". Washington Post reporter Suzanne McGee called for Wall Street to make a sort of public apology to the nation, and expressed dismay that people such as Goldman Sachs chief executive Lloyd Blankfein hadn"t expressed contrition (侮悟) despite being sued by the SEC(Securities and Exchange Commission)in 2009. McGee wrote that "Bankers aren"t the sole culprits, but their denials of responsibility and the occasional vague and waffling expression of regret don"t go far enough to deflect anger". But chief banking analyst at Goldman Sachs, Richard Ramsden, is "unapologetic" and sees "banks as the dynamos(发电机)that power the rest of the economy". Ramsden believes "risk-taking is vital". Others in the financial industry believe they"ve been unfairly criticized by the public and by politicians. Images of Wall Street and its figures have loomed large. The 1987 Oliver Stone film Wall Street created the iconic figure of Gordon Gekko who used the phrase "greed is good", which had an unexpected cultural influence, not causing them to turn away from corporate greed, but causing many young people to choose Wall Street careers.

单选题According to the author, what will NOT happen if trial disappears in the United States? ( )

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Which of the following statements is FALSE according to the passage?

单选题Abortion. The word alone causes civil conversation to flee the room. This is largely because the prochoice and pro-life positions are being defined by their extremes, by those who scream accusations instead of arguments. More reasonable voices and concerns, on both sides of the fence, are given little attention. For example, pro-life extremists seem unwilling to draw distinctions between some abortions and others, such as those resulting from rape with an underage child. They would make no exception in the recent real-life case of a woman who discovered in her fifth month that her baby would be born dead due to severe disabilities. On the other hand, pro-choice extremists within feminism insist on holding inconsistent positions. The pregnant woman has an unquestionable right to abort, they claim. Yet if the biological father has no say whatsoever over the woman's choice, is it reasonable to impose legal obligations upon him for child support? Can absolute legal obligation adhere without some sort of corresponding legal rights? The only hope for progress in the abortion dialogue lies in the great excluded middle, in the voices of average people who see something wrong with a young girl forced to bear the baby of a rapist. Any commentary on abortion should include a statement of the writer's position. I represent what seems to b ea growing "middle ground" in pre-choice opinion. Legally, I believe in the right of every human being to medically control everything under his or her own skin. Many things people have a legal right to do, however, seem clearly wrong to me: adultery, lying to friends, walking past someone who is bleeding on the street. Some forms of abortion fall into that category. Morally speaking, my doubts have become so extreme that I could not undergo the procedure past the first three months and I would attempt to dissuade friends from doing so. Fanatics on both sides are using reprehensible and deceitful tactics. An honest dialogue on abortion must start by re-setting the stage, by denouncing the approaches that block communication.
