Experts 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 10-year-old
boy put up one finger with his eyes still closed, begging(请求) 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 without a good night sleep, students seem to be weaker (虚弱) 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 the students should develop good study habits.
So some cleverstudents never study late, they are able to work well in class.
