THE 'China Daily', a newspaper, reports that the average student goes to sleep at 00:30 am. Even if that's an exaggeration (夸張), it's too close to the truth. Scientists say teens should sleep nine hours each night. But that's hard to do.
    Some even "pull all-nighters". These are lazy students who have homework due (到期) the next day that they haven't done. In the morning they don't look healthy and you can tell who's been doing it.
    One reporter did a survey on the problem. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!
    Maybe the students’ lack (缺乏) of sleep is because of laziness - But in fact, few of them are lazy- or maybe it's because they have too much to do in middle schools.

Zhang Jialiang, a student in a middle school, usually go to bed around midnight. He says, “If I stayed up past 00:30 am, I wouldn't get any work done. I'd be falling asleep at my desk. My classes begin at 6:50 am. I'm partly awake in my first class. By the second, I'm slightly drowsy(困倦的). By my third class, I'm sleepy. By midday I'm finally wide-awake. But by 3:00 pm, I'm slowing down again. Yet I get more sleep than the China Daily's 'average student'.”
    Most Chinese middle schools seem to have a similar problem with sleepy students.
    Middle school classes start at 6:50 am, so students have to wake up one and a half hours before that to get ready and catch the bus. It's believed that lack of sleep can damage (損害) both grades and health.
    Some schools are paying attention. Classes in those schools start at 7:30 am.
