8、your blood is iron poor, a supplement might help your health and your ability to sleep. Tips for a better sleep environment Make sure your bed is large enough and comfortable.

9、rapeutic (治疗的) shaped foam pillows that cradle your neck or extra pillows that help you sleep on your side. Get comfortable cotton sheets. Make your bedroom primarily a place for sleeping. It is not a good idea to use your bed for paying bills, doing work, etc. Help your body recognize that this is

10、a place for rest. Keep your bedroom peaceful and comfortable. Make sure your room is well ventilated and the temperature consistent. And try to keep it quiet. You could use a fan or a “white noise“ machine to help block outside noises. Hide your clock. A big, illuminated digital clock may cause you

11、to focus on the time and make you feel stressed and anxious. Place your clock so you cant see the time when you are in bed. Tips for a better pre-sleep ritual Keep a regular schedule. Try to go to bed and wake up at the same time everyday, even on the weekends. Keeping a regular schedule will help y

Dont read anything job-related or watch a stimulating TV program (commercials and news shows tend to be al

21、erting). Dont expose yourself to bright light. The light gives cues to your brain that it is time to wake up. Consider changing your bedtime. If you are experiencing sleeplessness or insomnia consistently, think about going to bed later so that the time you spend in bed is spent sleeping. If you are

22、 only getting five hours of sleep at night, figure out what time you need to get up and subtract five hours (for example, if you want to get up at 6:00 am, go to bed at 1:00 am).

41、 Comprehensio(总题数：2，分数：355.00)Is there enough oil beneath the Arctic National Wildlife Refuge (保护区) (ANWR) to help secure Americas energy future? President Bush certainly thinks so. He has argued that tapping ANWRs oil would help ease Californias electricity crisis and provide a major boost to the c

42、ountrys 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

43、 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 to 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 wou

44、ld 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. “Weve never had a documented case of an oil rig chasing deer out on

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,

46、a drop in the bucket that would do virtually nothing to ease Americas 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 ANWRs impact on the California

47、 power crisis, environmentalists point out that oil is responsible for only 1 % of the Golden States electricity outputand just 3% of the nations. （分数：177.50）(1).What does President Bush think of tapping oil in ANWR?（分数：35.50）A.It will increase Americas energy consumption.B.It will exhaust the nations oil reserves.C.It will help reduce the nations oil imports.D.It will help secure the future of ANWR.(2).We learn from the second paragraph that the American oil industry_.（分数：35.50）A.shows little interest in tapping oil in ANWRB.expects to stop oil imports fro
