Experts（专家）say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her boy who was 10 years old put up one finger（手指） with his eyes still closed, begging（请求）for one more minute to sleep. Like thousands of students “early bir ds” in China, he has to get up before six every morning.
