参考答案：One possible version

The day before yesterday, we had a discussion about our homework. Many students thought it was good to do lots of homework, but some students didn't think so.

Many students thought doing homework could help them review what they learned and solve the problems alone. It's their duty to finish homework, they should learn how to plan time well.

But some students thought it took much time and they couldn't rest well. They couldn't do the things they liked, either. Some homework was too difficult to finish.

In My Opinion, it's necessary and helpful to do some suitable homework.
