In China, more and more middle school students are getting    1    sleeping time than before. Most
students sleep    2   than nine hours every night because they have much homework    3  . Some
homework is    4   by their teachers, and some by their    5  . Also, some students don't know how to 
   6   time. They are not careful enough while they do their homework, so it takes them a lot of time.
Some students    7   too much time watching TV programmes or    8   computer games. They stay up
very late. Some students have to    9   early every morning on weekdays to get to school on time by
bus or bike. It can be a long way from home to school.
     Schools and parents should cut down some of the homework so that the children can   10   more
than nine hours of sleep every night for their health. As we all know, children are our country's future.
They should be well cared for.
