假如你是李华， 收到笔友Mary的来信如下， 请你针对信中Mary遇到的问题进行回复， 给她提出建议。
Dear Li Hua ,
How are you ?
I am having trouble with my desk mate Jenny at the moment . Last week , we had a maths test .The test was important and everyone had prepared for it except Jenny .
During the test , she asked me to help her. I refused and didn’t let her copy from my paper .As a result , she failed the test .She is angry with me and hasn’t talked to me since then . Now I don’t know how to deal with this problem .Can you give me some advice ?
I’m looking forward to your reply .
Yours
Mary
写作要点：
给Jenny 写信，告诉她诚实的重要性及作弊的坏处。
帮助她学习数学，使她对学习数学充满信心。
如果她的英语比你的好，可以让她帮助你学英语，因为互帮互助可以加深（deepen ）友谊。
词数要求：100左右（开头已给出， 不计入总词数）
Dear Mary，
I’m sorry you are having trouble with your friend.
