       Experts say that students usually need eight to ten hours' sleep at night , but more 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 10-year-old boy put up one finger with his eyes still closed ,begging(央求) for

one more minute to sleep . Like thousands of student "early birds" in China, he has to get up before six

every morning.

       A report shows that 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 reason why students stay up late . Some watch TV or play the computer games late into the night.

       Experts have ever said that students should develop good study habits. So some clever students

never study late, they are able to work well in class.
