In conclusion, the homework are able to promote the students consolidating of the knowledge after the school.The student can develop their self-control by doing homework,and in fact many pupils can't intend themselves.What's more,It is obvious that teacher can know and supervise the student learning by revising and correcting their compositions. So I think that students should have homework. But don't give too much homework, we should be able to actually do it and not feel too stressed.
