2013年托福考试模拟试题样题5

　　-Questions 43-46. Listen to a radio broadcast about sleep.

　　- W: Do you have trouble sleeping at night? Then maybe this is for you. When you worry about meeting sleep and toss and turn trying to find a comfortable position, you’re probably only making matters worse. What happens when you do that, is that your heart rate actually increases, making it more difficult to relax.

　　- You may also have some had habits that contribute to the problem. Do you rest frequently during the day? Do you get virtually no exercise of do you exercise strenuously late in the day? Are you preoccupied with sleep, or do you sleep late on weekends? Any or all of these factors might be leading to your insomnia by disrupting your body’s natural rhythm. What should you do, then, on those sleepless nights? Don’t bother with sleeping pills. They can actually cause worse insomnia later. The best thing to do is drink milk or eat cheese or tuna fish. These are all rich in amino acids and help produce a neurotransmitter in the brain that induces sleep. This neurotransmitter will help you relax, and you’ll be on your way to getting a good night’s sleep.

　　-Question 47-50. Listen to a professor talk to his city planning class.

　　- M: Today we’ll examine the role that private transportation---namely, the automobile---plays in city planning. A number of sociologists blame the automobile for the automobile for the decline of the downtown areas of major cities. In the 1950’s and 1960’s the automobile made it possible to work in the city and yet live in the suburbs many miles away. Shopping patterns changed: instead of patronizing downtown stores, people in the suburbs went to large shopping malls outside the city and closer to the home. Merchants in the city failed; and their stores closed. Downtown shopping areas became deserted. In recent years there’s been a rebirth of the downtown area, as many suburbanites have moved back to the city. They’re done this, of course, to avoid high ways clogged with commuters from the suburbs. I’ve chosen this particular city planning problem---our dependence on private transportation---to discuss in groups. I’m hoping you all will come up with some innovative solutions. Oh, and don’t approach the problem from a purely sociological perspective; try to take into account environmental and economic issues as well.

　　47.How did the automobile affect the work force in the 1950’s and 1960’s?
