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 see1children study late. They will think their children work very 2, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy puts up one finger with his eyes still 3, begging(请求) for one 4 minute to sleep. Like thousands of students who are called "early birds" in China, he has to get up before six every5.
A report 6 that without a good night's sleep, students seem to be weaker than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only 7why students stay up late. Some watch TV or play the computer games 8into the night.
Experts have once said that the students should develop 9study habits. So some clever students 10study late, and they are able to work well in class.
