阅读下列短文并按要求回答问题。

     In China, more and more middle school students are getting shorter sleeping time than before. Most

students sleep less than nine hours every night, because they have much homework to do. Some homework

is given by their teachers, and some by their parents. Also, some students don't know how to save time.

They are not careful enough while they do their homework, so it takes them a lot of time. Some students

spend too much time watching TV or playing computer games. They stay up (熬夜) very late. Some students

have to get up early every morning on weekdays to get to school on time by bus or by bike. It can be a long

way from home to school. It will probably make them sleepy (困的) during school hours.

     Schools and parents should cut down some of the homework so that our children can enjoy more than

nine hours of sleep every night for their health. For children, they should make the most (best use) of their

time. When they have enough time for sleeping, they will find it much better for both their study and health.
