A recent survey in Beijing shows that many middle school students suffer from a lack of sleep.
北京最近的一項調查顯示，許多中學生睡眠不足。
Scientists suggest that junior high school students should sleep at least nine hours a day and senior high school students no less than eight hours.
科學家建議，初中生每天應該睡至少9個小時，高中生不少于8個小時。
However, many students cannot get enough sleep.
然而，許多學生不能得到足夠的睡眠。
Therefore, they might fall asleep in class or while doing their homework.
因此，他們可能會在上課或做作業時睡著。
So it is not surprising that they get lower grades than those who get enough sleep.
因此，他們比那些睡眠充足的人成績更差也就不足為奇了。
Many students are short of sleep because they have heavy workloads, poor study habits, or long commuting time, according to an expert.
據一位專家介紹，許多學生睡眠不足是因為他們的學習任務重大，學習習慣不佳，或者通勤時間過長。
Also, many students have either a telephone or a computer in their bedroom.
而且，許多學生的臥室里都有一部電話或一臺電腦。
As a result, they hardly go to sleep before 11:00 p.m., but they have to get up early to go to school.
因此，他們很少在晚上11點之前睡覺，但是他們不得不早起去上學。
