Do You Go To Sleep In Class?

The "Acronym", our student newspaper, reports that most students go to sleep at 1: 30 a. m. Even if that's an exaggeration(夸张), it's too close to the truth. Scientists say teenagers 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 to(到期) the next day that they haven't done. In the morning they don't look healthy and you can tell who has been doing it.

One of my classmates did a survey(调查) 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 our lack of sleep is because of laziness—I think I'm a lazy student—or maybe it's because we have too much to do in American high schools.

I usually go to bed around midnight. If I stayed up past 1: 30 a. m., I wouldn't get any work done. I'd be falling asleep at my computer. My classes begin at 7:30 a.m. I'm partly awake in my first class. By the second, I'm slightly tired and sleepy. By my third class, I'm sleepy. By midday I'm finally wide-awake. But by 3: 00 p. m., I'm slowing down again.

Most American high schools seem to have such a problem.

High school classes start at 7: 30 a. m., 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 do harm to both grades and health.

Some schools are paying attention. Classes in those schools start at 8:30 a. m.
