单选题{{B}}Text 3{{/B}} The visual arts are a class of art forms, including painting, sculpture, photography, and others, that focus on the creation of artworks which are primarily visual in nature. The visual arts are distinguished from the performing arts, language arts, and other such classes of artwork. The definition is not strict, and many artistic disciplines involve aspects of the visual arts as well other types. In Britain until recently the fine arts-painting, sculpture, printmaking, and so on-were seen as distinct from craft disciplines and the various metalworking disciplines. This distinction arose from the Arts and Crafts Movement whose political aim was to value daily art forms as much as high forms. The result of the conflict between the two groups was to politicize the products of what we now know as visual artists. British art schools made a clear distinction between the fine arts (a term that hints at their supposed superiority) and the crafts in such a way that a craftsperson could not be considered a practitioner of high art. Although this is no longer the case, the inequality between the crafts or applied arts and the so-called fine arts still exists in some quarters. A similar stigma exists in the US, where "arts and crafts" has a very particular meaning, referring to the sort of artwork first taught in elementary school and also (later in life) a variety of kitsch, household artwork. Most craftspeople are still seen as practicing something other than "fine art" among the traditional art school set, but, of course, can produce "high art", in any medium.

单选题 Questions 11～14 are based on the following dialogue about Amy's view on date.

单选题Poverty exists because our society is an unequal one ,and there are extremely strong and powerful political pressures to keep it that way. Any attempt to redistribute wealth and income in the United States will inevitably be opposed by powerful middle and upper class interests. People can be relatively rich only if others are relatively poor, and since power is concentrated in the hands of the rich, public policies will continue to reflect their interests rather than those of the poor. As Herbert Gans (1973) has pointed out, poverty is actually functional from the point of view of the non-poor. Poverty ensures that" dirty" work gets done. If there were, no poor people to scrub floors and empty waste, these jobs would have to be rewarded with high incomes before anyone would touch them. Poverty creates jobs for many of the non-poor, such as police officers, welfare workers, pawnbrokers, and government bureaucrats. Poverty makes life easier for the rich by providing them with cooks, gardeners, and other workers to perform basic chores while their employers enjoy more, pleasurable activities. Poverty provides a market for inferior goods and services, such as day-old bread, run-down automobiles, or the advice of incompetent physicians and lawyers. Poverty makes middle-class values seem acceptable. To the middle class, the fate of the poor — who are supposed to lack the virtues of thrift, honesty, and a taste for hard work — only confirms the desirability of qualities the poor are thought to lack. Poverty also provides a group that can be made to absorb the costs of change. For example, the poor suffer the main part or force of unemployment caused by automaton, and it is their homes, not those of the wealthy, that are demolished when a route has to be found for a new highway. There is no intentional, conscious "secret plan" of the wealthy to keep the poor in poverty. It is just that poverty is an inevitable outcome of the American economic system; which the poor are politically powerless to influence change.

单选题Cars account for half the oil consumed in the US, about half the urban pollution and one-fourth the greenhouse gases. They take a similar oil of resources in other industrial nations and in the cities of the developing world. As vehicle use continues to increase in the coming decade, the US and other countries will have to deal with these issues or else face unacceptable economic, health-related and political costs. It is unlikely that oil prices will remain at their current low level or that other nations will accept a large and growing US contribution to global climatic change. Policymakers and industry have four options: reduce vehicle use, increase the efficiency and reduce the emissions of conventional gasoline-powered vehicles, switch to less harmful fuels, or find less polluting driving systems. The last of these -- in particular the introduction of vehicles powered by electricity -- is ultimately the only sustainable option. The other alternatives are attractive in theory but in practice are either impractical or offer only marginal improvements. For example, reduced vehicle use could solve traffic problems and a host of social and environmental problems, but evidence from around the world suggests that it is very difficult to make people give up their cars to any significant extent. In the US, mass transit ridership and carpooling have declined since World War Ⅱ. Even in western Europe, with fuel prices averaging more than $1 a liter (about $ 4 a gallon) and with easily accessible mass transit and dense populations, cars still account for 80 percent of all passenger travel. Improved energy efficiency is also appealing, but automotive fuel economy has barely made any progress in 10 years. Alternative fuels such as natural gas, burned in internal-combustion engines, could be introduced at relatively low cost, but they would lead to only marginal reductions in pollution and greenhouse emissions (especially because oil companies are already spending billions of dollars every year to develop less polluting types of gasoline).
