I moved to the new town with my parents two months ago. I miss you and friends very much. And I am very unhappy every day. I have many troubles. First, the lessons here are very hard, and what's worse, math is harder than ours and I don't have a right math book. Second, I have no friends here and I don’t know how to talk with the students and teachers. I don't know if they are friendly. I am very upset and don't know what to do. What can I do? Do you have any good ideas for me？
I'm looking forward to hear from you soon.
Yours,
Mike
2．习作正文：
Dear Mike,
How are you? Our friends and I am (1) very happy to receive your e-mail. We are very sorry to know you have so many troubles and you are not happy at all. There are a lot of things you could do. You could write e-mails often if you miss us. We could think out many good ideas for you. You should ask your new teachers to help you to study subjects especially math. They could be happy to help you. You should borrow a math book to (2) your teacher or new classmates, or you could buy a new book. You should be friendly and smile to others. You should talk with your new classmates and play with them often. You could find new friends soon.
keep out, call sb. up, on the phone, pay for, the same as, in style, out of style, get on, as ... as possible, all kinds of, on the other hand, find out
（4）在正文的后面可以写上祝福语或者表达我们的心愿。如：I'm looking forward to hearing from you. / Please write to me soon. / Best wishes to you and your parents. / Good luck to you. / Take good care of yourself.
（1）此句涉及到主谓一致的情况，做主语的是our friends and I，应视为复数，所以am应改为are。
（2）此句的词组为borrow sth. from sb.（从某人那借某物），所以此处的to应改为from。
（3）各别句子过长，过于复杂，不利于阅读，可适当地变成几个短句子。
（4）虽然本电子邮件回答了材料中所提到的问题，但是如果添加几个过渡词会文章会显得更有条理。
