2.What does the author think of teenagers’ sleep? 选项： A: Being young and healthy, teenagers need less sleep in the morning. B: When babies get older, they start to sleep most of the time. C: It’s hard to determine if eight hours’ sleep is enough for teenagers. D: Teenagers need only nine to ten hours’ sleep per night.

3.Babies sleep about eighteen hours a day. Mrs. Thatcher and Napoleon both said they only needed to do it three or four hours a night. Sleep. No one can live without it. But how much do we really need?

Research by the National Sleep Foundation in Washington says that we all need eight hours' sleep every night. Scientists have found that people who sleep for less than six and a half hours a night are more often ill than people who sleep for eight hours. Going without sleep also increases the chance of serious illness. Workaholics（工作狂） who sleep for less than five hours often die young, and do less well at work.

The scientists found that adults usually sleep for seven hours a night, with 32% sleeping less than six hours.

It also says that the idea that we need less sleep as we get older is completely untrue.“People have no idea how important sleep is to their lives,” Dr. Thomas Roth, director of the Foundation says.“Good health needs good sleep.”

“But not too much of it,” says Professor Jim Horne of Loughborough University.“Sleep is like food and drink,” he believes.“You would always like to have a little bit more, but that doesn't mean you need it.” Professor Horne studied a group of people who could spend as many hours as they wanted in bed, after ten hours they didn't find it any easier to get up in the morning. And people who sleep for more than nine hours a night die younger than people who usually sleep for seven or eight!

6.Passage 3:If you have trouble getting a good night’s sleep, don’t have an alcoholic drink before bedtime. While alcohol can certainly knock you out, it also damages the quality of sleep you’ll get. That’s because chemically interferes with dreaming, an important part of restful sleep. Also, avoid beverages and foods that contain caffeine, such as coffee, most teas, colas, and chocolate. Caffeine can stimulate you, making sleep difficult or impossible. A better before-bed choice is a milk, which contains a mild, sleep-inducing type of protein. Another piece of good advice is to exercise during the day; this can leave you tuckered out enough at night to fall promptly and soundly asleep. But do avoid exercise right before bedtime, as its immediate effects are more stimulating than relaxing. Last, try to get up at about the same time every day; this practice will help your body establish a solid sleep and wake cycle. Varying your hours too much an confuse your body’s “inner clock.”选项： A:People have trouble getting a good night’s sleep; B:Having an alcoholic drink before bedtime helps sleep; C:There are several ways to get a good night’s sleep; D:The better milk you choose, the better your sleep will be

9.Everybody needs sleep. Sleep helps us to restore many body functions. For example it helps us to recover from tiredness. Sleep can also organize memories, as well as help us to recover memories. After we learn something new, sleep may solidify the learning in our brain.How much sleep do we need then? It depends on a number of factors. Generally for adults, 7 to 8 hours a night appear to be the best amount of sleep, although some people may need as few as 5 hours or as many as 10 hours of sleep each night. Teenagers may need about 9 hours of sleep per night. For children, 10 or more hours should be needed every day.Unfortunately, nowadays many students don’t have enough time to sleep. According to a recent survey, most middle school students only have an average of less than 7 hours’ sleep each night, much less than required. Some students, especially some of those who are preparing for the entrance examinations for higher schools, sleep for only four to five hours every day, according to the researchers.The government has called on schools and teachers“to reduce the students’ burden”. But some education experts suggest that more measures be taken to assure the students’ sleeping time.[写作内容]1. 概括上文中的内容;2. 阅读上文后，谈谈你的感想：(1) 学生睡眠不足的主要原因： (2) 就如何改变现状提出你的建议。[写作要求]你可以使用实例或其他论述方法支持你的论点，也可以参照阅读材料的内容，但不是直接引用阅读材料中的句子。
