1.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。
