英语的写信格式如下：
1、信头：发信人的地址和日期，写在信纸的右上角。
2、称呼：收信人的地址和称呼。写在信头之下，从信纸的左边开始。写信给熟悉的人，如王明一般用Dear Wang Ming或Dear Mr. Wang。
3、信的正文：信的主体部分，从称呼的下一行到结束语前，第一段顶头写。
4、结束语：正文下面的结束客套话。常用Yours sincerely，Yours ever或者Yours或Yours truly，Truly Yours等。
5、签名：发信人的签名，写在结束语的下面。
英语信件类型：
英文信件书写主要以能够让收信人获得信件内容为主要目的，因此，邮件或书信的语言应该尽量言简意赅，简明扼要的表达出来主要意图。英文书信表达主要分为以下几类：请求信，建议信，道歉信，抱怨信，感谢信，求职信及咨询信等。
尽管不同类型的信件中具体的诉求内容不同，每种书信类型的结构构架极其相似。
英语四级通用作文：
What do Students Need English For? Today, it seems that nearly everyone is studying English, especially students. But what do they study English for? A survey made by a teacher at a university gives us some hints.
The results of the survey suggest that students need English for different purposes. Most students learn English because they need to read English textbooks or journals or attendEnglish lectures, while only a few students use it to talk to Englishspeaking visitors.
Attend_seminars.and write letters, etc.There are also some differences between economics students and engineering students.
Compared with engineering students, economics students need to read English business textbooks and write reports in English.
Therefore,fromthe result of the survey,we can see that the purposes students learn English for vary with the academic field students study in.
Whatever the purposes are, one thing is certain: Students need English, and English teaching should be strengthened in universities.
