书信我们分为两部分：信封和内容。
1、信封的写法。
英语信封正面的左上角，写发信人的姓名和地址。在信封的正面中央偏左一点，写收信人的地址和姓名。
英语信封上的地点名称由小到大，视其长短可占二至五行不等。
寄信人只写姓名，不写头衔。但是，收信人一般都在名字前加上头衔，以示礼貌和尊敬。对于没有官衔和学衔的人士，通常在姓名前写上Mr., Mrs.,或Ms.。
信封的写法，一般来说，很少出现在中考英语的作文中。
2、内容。
英文信一般可以分为下列几个部分。
1)信端(Heading)即写信人的地址和发信日期。
2)收信人姓名地址
3)称呼
4)信的正文
5)结束语
6)签名
有的时候，出题者会让考生写e-mail。e-mail的写法和书信的写法基本一致。只不过少了书信在信封上的繁琐。
根据中文大意，写出意思连贯、符合逻辑、不少于50词的短文。
假设你叫王明，昨天收到了笔友David的e-mail，得知他不久要到北京来学习中文。他想了解如何学好中文。请你用英文给他回复一封e-mail，介绍学习中文的体会和方法，提出你的建议，以及表达你帮助他学好中文的愿望。
Dear David,
I'm glad you'll come to Beijing to learn Chinese. Chinese is very useful, and many foreigners are learning it now. It's difficult for you because it's quite different from English. You have to remember as many Chinese words as possible. It's also important to do some reading and writing. You can watch TV and listen to the radio to practise your listening. Do your best to talk with people in Chinese. You can learn Chinese not only from books but also from people around you. If you have any questions, please ask me. I'm sure you'll learn Chinese well.
Hope to see you soon in Beijing.
Yours,
Wang Ming
