     Middle school students have far too much homework. They usually have to sit up three or four hours

every night doing their homework. Now one school in my hometown has made a rule of limiting (限制)

homework. The homework is limited to an hour a day and the students have no homework on the weekend.

I think this is an excellent idea that will allow students to live better and healthier lives.

     Less homework will give students more time to enjoy other pastimes (休闲活动). I have many books

which I received as gifts from my parents and friends. They have been kept there on my shelf for several

years! Because of homework, I will have not read a single one of them. With less homework, students will

be freer to develop their interests in art, music and other hobbies.

     More time free from homework will get our physical health better. Many students like sports, but they

have little time to play football, basketball, volleyball and so on. They hardly have time to have a trip or take

part in any social activities. They must spend so much time solving math problems and doing grammar

exercises. Besides, staying up late to finish their homework leaves many students exhausted in the morning.

Not getting enough sleep is not only unpleasant; it also makes students more likely (有可能得) to get colds

and other illnesses.
