单选题 Is there enough oil beneath the Arctic National Wildlife Refuge (保护区) (ANWR) to help secure America"s energy future? President Obama certainly thinks so. He has argued that tapping ANWR"s oil would help ease California"s electricity crisis and increase the country"s energy independence, thus reducing its oil reliance on other countries. But no one knows for sure how much Crude oil lies buried beneath the frozen earth.
The oil industry goes with the high end of the range, which could equal as much as 10% of U.S. consumption for as long as six years. By pumping more than 1 million barrels a day from the reserve for the next two or three decades, lobbyists claim, the nation could cut back on imports equivalent to (等于) all shipments to the U.S. from Saudi Arabia. An oil increase would also mean a multi billion-dollar windfall (意外之财) in tax revenues, royalties (开采权使用费) and leasing fees for Alaska and the Federal Government. Best of all, advocates of drilling say, damage to the environment would be insignificant." We"ve never had. a document case of oil rig chasing deer out onto the pack ice," says Alaska State Representative Scott Ogan.
Not so fast, say environmentalists. The National Resources Defense Council says there may be no more than 3.2 billion barrels of oil in the coastal plain of ANWR, a drop in the bucket that would do virtually nothing to ease America"s energy problems. And consumers would wait up to a decade to gain any benefits, because drilling could begin only after much bargaining. As for ANWR"s impact on the California power crisis, environmentalists point out that oil is responsible for only 1% of the Golden State"s electricity output and just 3% of the nation"s.

单选题 What does President Obama think of tapping oil in ANWR?

【正确答案】 C

【答案解析】[解析] 第一段第三句：“He has argued that tapping ANWR"s oil would help ease California"s electricity crisis and increase the country"s energy independence, thus reducing its oil reliance on other countries. ”
事实细节题。根据定位句可知，奥巴马声称北极国家野生动物保护区的石油将有助于缓解加州的电力危机并促进该国的能源独立，从而减少在石油方面对其他国家的依赖性。即减少石油的进口。故选C。

单选题 We learn from the second paragraph that the American oil industry ______.

【正确答案】 A

【答案解析】[解析] 第二段。
推理判断题。根据定位段可知，这一段主要讲到了石油开采可能会带来的一些经济上的实惠，所以A正确。美国石油行业并没有夸大美国对于进口石油的依赖，所以B不对；美国石油行业对在ANWR开发石油非常感兴趣，所以C不对；根据第二段中的“the nation could cut back on imports equivalent to (等于) all shipments to the U.S. from Saudi Arabia”可知，只是降低从Saudi Arabia进口石油，而没有说停止进口，所以D不对。故选A。

单选题 Those against oil drilling in ANWR argue that ______.

【正确答案】 B

【答案解析】[解析] 第三段第二句：“The National Resources Defense Council says there may be no more than 3.2 billion barrels of oil in the coastal plain of ANWR, a drop in the bucket that would do virtually nothing to ease America"s energy problems. ”
事实细节题。根据定位句可知，在ANWR的沿岸平原地带可以经济性开采的石油不超过32亿桶，这个数量对于缓解美国的能源问题实际上起不到什么作用，简直是沧海一粟。故选B。

单选题 What do the environmentalists mean by saying "Not so fast" in the third paragraph?

单选题 It can be learned from the passage that oil exploitation beneath ANWR"s frozen earth ______.

【正确答案】 A

【答案解析】[解析] 全文。
推理判断题。文章提到北极的国家野生动物保护区地下蕴藏着大量石油．针对其对美国的影响，有两种不同的观点。尤其是第三段第三句“And consumers would wait up to a decade to gain any benefits, because drilling could begin only after much bargaining. ”说明了石油开发只有在多次谈判后才会开始，即石油开发还面临着许多的争议。故选A。
