     It is true that many students at school these days are suffering from a serious lack of sleep. Many of

them feel tired and lose their interest in studying. 　

     Take my classmates and me as examples. Now we're students in Grade Eight. We have a lot of books

to read and we have to study hard every day. When we get home after evening classes, we still have a lot

of homework to do. When we finish our work, it is often eleven or twelve o'clock. Therefore, some of us

fall asleep in class during the day. 　

     To solve this problem, we need time for more exercise to make us physically healthy. Also, teachers

should give less homework to us. Most important of all, measures should be taken to improve the education

system.
