问题     The federal automobile efficiency standards announced this week are an important step on America’s path to a lower-carbon and more-secure energy future. They are expected to yield multiple benefits; reduced dependence on foreign oil, fewer greenhouse gas emissions, consumer savings at the pump and a more competitive auto industry. They may also serve as proof that well-tailored government regulation can achieve positive results and that consensus among old enemies—in this case environmentalists and the car companies—is possible even at a time of partisan(党派的)disagreement.
    The standards build on a 2009 agreement that established a unified set of rules governing fuel economy and carbon dioxide pollution from automobiles and light trucks. Those rules covered model years 2012-16; the new rules cover 2017 to 2025. Taken together, the two sets of rules would increase fuel efficiency from today’s average of about 29 miles per gallon to 54.5 miles per gallon when they are fully effective in 2025. This is expected to result in a cut of 40 percent to 50 percent in fuel consumption and roughly equivalent cuts in greenhouse gas emissions.
    The White House says the rules would reduce oil consumption by two million barrels a day by 2025; the nation now consumes 19 million barrels a day and imports just less than half that amount. And while fuel-efficient cars will cost more initially, lower fuel use is expected to save consumers up to $8,000 over the life of their vehicles.
    The battle for greater fuel economy goes back years and involved many players: California, which in 2002 passed its own law regulating greenhouse gas emissions from vehicles sold there; environmentalists, who pressured the Environmental Protection Agency to impose similar rules nationwide; the Supreme Court, which in 2007 authorized the agency to move forward; and Congress, which ordered the Department of Transportation to update fuel economy standards that had been largely untouched since 1975. President Obama’s contribution was to bring about a consensus among the agencies, the states, the automakers and the interest groups on federal and state standards that reduced fuel use and gave industry the regulatory certainty it needed to move forward.
    It is a model of public-private cooperation. Even so, the Romney campaign has called the rules "extreme" and House Republicans have threatened to roll them back. That would be a grave harm to consumers, the auto companies, the economy and the planet. [br] According to the White House, ______.

选项 A、the nation doesn’t need to import many oil from foreign countries
B、lower fuel use saves consumers more than $ 8,000 during their lives
C、fuel-efficient cars are more expensive than normal automobiles
D、the nation will consume two million barrels of oil a day by 2025

答案 C

解析 事实细节题。由定位句可知,一开始燃油经济性汽车花费较高,但低油耗预计能帮助消费者在整个汽车使用寿命中节省高达8 000美元的费用,因此C)“燃油经济性汽车比普通汽车价格高”为本题答案。A)“美国不需要从外国进口太多石油”和原文相反,上文提到美国每天进口的石油量占它每天消耗量的一小半,故排除;B)“更低的石油消耗帮助消费者一生中节约8 000多美元”是对原文的误解,根据原文,钱是在汽车使用期间节省的,而不是在人的一生中节省的,故排除;D)“到2025年,美国每天消耗200万桶石油”是美国石油消耗量减少的幅度,而不是具体的消耗量,故排除。
