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).
Which of te following is the best solution to the problems mentioned in the passage?
选项
A、The designing of highly efficient car engines.
B、A reduction of vehicle use in cities.
C、The development of electric cars.
D、The use of less polluting furls.
答案
C
解析
细节题。第二段首先提出了几种解决汽车带来的问题的选择,然后在第二句说;The last of these...is ultimately the only sustainable option(最后一种——尤其是引入电动汽车——才是最终惟一可持续的选择),因此本题选[C] 。
