Your friend is having trouble in class and asks to copy your work .what should you do?简单几句回答就好~

refuse but help him or find an excuse.

Help hime to find out the answers to the problem instead of telling him directly or allowing him to copy my answer.If I tell the answer directly or give him the copy,he will never know how to deal with this problem.Maybe,worse,he will get lazy thinking in the future.It is not good for him in future study.And I won't be his friend-indeed to if I do that.
