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For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain, Lewis and Clark journeyed into the American wilderness to find out what the U. S. had acquired when it purchased Louisianan, and the Apollo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms as humanity"s next great terra incognita (未探明之地). And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet"s reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: are there experiment that only human could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
