As we all know, homework plays an important role in Chinese education. Students do homework to strengthen what they've learnt in class and meanwhile prepare for the new lessons.
But too much homework is really a heavy burden for Chinese students. They have little time to take physical exercise and some wear thick glasses because exercises take up most of their spare time. They also suffer punishments if work is done badly or late. After years of bad homework experiences, some of them lose interest in study and hate school life.
So I think homework is necessary, but it needs to be well designed and shouldn't take up all the students' spare time. Only in this way can the students find pleasure in their homework and become more interested in study.
