Cars account for half the oil consumed in the U.S. , about half the urban pollution and one fourth the greenhouse gases. They take a similar toll (损耗) 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 U.S. 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 U. S. 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 (可持续的) 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 U.S. mass-transit rider ship and carpooling (合伙用车) 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 (边缘的最低限度的) 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).
选项
A、consume half of the oil produced in the world
B、have serious consequences for the well-being of all nations
C、widen the gap between the developed and developing countries
D、impose an intolerable economic burden on residents of large cities
答案
B
解析
细节题。根据第一段,美国及其他国家必须处理这些问题,否则将面临难以接受的经济、健康及政治损失(or else face unacceptable economic,health-related and political costs),故B是正确答案。选项A、C和D均仅涉及问题的某个方面,只有B代表了私人轿车继续增长的真正后果,故B是正确答案。
