　　Exercise is one of the few factors with a positive role in long-term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to “light” beer and low-calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.

　　In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts: for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede half a point here. “Exercise by itself is a very tough way to lose weight,” says York Onnen, program director of the President’s Council on Physical Fitness and Sports.

　　Still, exercise’s supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.

　　If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.{来源：考{试大}

　　Is there enough oil beneath the Arctic National Wildlife Refuge (保护区) (ANWR) to help secure America’s energy future? President Bush certainly thinks so. He has argued that tapping ANWR’s oil would help ease California’s electricity crisis and provide a major boost to the country’s energy independence. But no one knows for sure how much crude oil lies buried beneath the frozen earth with the last government survey, conducted in 1998, projecting output anywhere from 3 billion to 16 billion barrels.

　　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 three decades, lobbyists claim, the nation could cut back on imports equivalent to all shipments to the U.S. from Saudi Arabia. Sounds good. An oil boom would also mean a multibillion-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 far, say environmentalists. Sticking to the low end of government estimates, the National Resources Defense Council says there may be no more than 3.2 billion barrels of economically recoverable 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 over leases, environmental permits and regulatory review. 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.

　　21. What does President Bush think of tapping oil in ANWR?

　　A) It will exhaust the nation’s oil reserves.

　　B) It will help secure the future of ANWR.

　　C) It will help reduce the nation’s oil imports.

　　D) It will increase America’s energy consumption.

　　22. We learn from the second paragraph that the American oil industry ________.

　　A) believes that drilling for oil in ANWR will produce high yields

　　B) tends to exaggerate America’s reliance on foreign oil

　　C) shows little interest in tapping oil in ANWR

　　D) expects to stop oil imports from Saudi Arabia

　　23. Those against oil drilling in ANWR argue that ________.

　　A) it can cause serious damage to the environment

　　B) it can do little to solve U.S. energy problems

　　C) it will drain the oil reserves in the Alaskan region

　　D) it will not have much commercial value

　　24. What do the environmentalists mean by saying “Not so fast” (Line 1, Para. 3)?

　　A) Oil exploitation takes a long time

　　B) The oil drilling should be delayed

　　C) Don’t be too optimistic

　　D) Don’t expect fast returns

　　25. It can be learned from the passage that oil exploitation beneath ANWR’s frozen earth ________.

　　A) remains a controversial issue

　　B) is expected to get under way soon

　　C) involves a lot of technological problems

　　D) will enable the U.S. to be oil independent
