    Doing homework not only can help children master the knowledge they have learned, but also can train their abilities of finishing the work alone, planning the time and doing the duties. But some children don't like to complete the work. Why?

    Some children feel it is very difficult to do their homework, because they can't understand their teacher clearly, and cannot follow their teacher's teaching process (过程). Maybe there is something wrong with their intelligence.

    But some children's intelligence is normal. They are even cleverer, but they don't listen to the teacher carefully. It is hard for them to sit well and pay attention to anything.

    Some children love their teacher and then like the subject. Their interest depends on the teacher who teaches them. So every teacher should make children love you and the subject you teach. So they can do their homework happily.
