At school,we learn plenty of knowledge,but actually we can't remember all.Doing homework can help you have a revision of what you have learnt.The teachers can also know what you don't understand through the homeworks.If there's no homework to do.our life would be so boring and haven't anything to do.The students might be lazy and spent all time on TVs,computer games etc.That's why homeworks are very important.
Hope can help you!!!!~
