Experts(專家) say that students usually need eight to ten hours' sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents usually feel happy to see their children studying late. They will think their children work very hard.
But not all parents think about this. Once a mother told us that every morning her l0-year-old boy puts up one finger with his eyes still closed, begging(乞求)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 if（如果) they don't have a good night's sleep, students will be tired(疲倦）next day. Many students have fallen asleep (入睡) during classes. Too much homework is not the only reason(原因) why students stay up late. Some watch TV or play games late in the night.
Experts ever say that students should develop (養(yǎng)成)good study habits. So some smart students never study late, and they can also work well in class.
