Li_Hua 写作方法指导 如何写信
英文信件由信头、信内地址、称呼、正文、结束语和签名等6个部分组成。 1．信头指的是寄信人的地址和寄信日期，写在第一页信纸的右上角，先写地址，后写日期。一般在比较正式的书信中才写地址，否则，写日期就够了。 2．信内地址通常指收信人的称谓和地址，常用在正式信件中，写在信头下面一二行处的信纸左边。先写姓名、头衔、后写地址。以上内容高考不涉及，只作了解就可以了。
3．称呼即对收信人的敬语，从左边顶格写，占一行。前面常加Dear...或My dear...亲近的人之间常用名字或昵称，写给不熟悉的人常在Dear或My dear后加上“某先生”或“某女士”等，后面通常用逗号。
4．正文是信的主体，需要写信人精密构思，条理清楚，完整正确地进行表达，并紧扣主体，适当发挥。英语回信通常先提到收到对方的信，并表示感谢，然后再回答对方的问题，或发表自己的意见。
5．结束语从中间偏右的地方开始写，也可以与正文齐头写。常用的表达方式为Yours truly，Yours sincerely或Sincerely，若是好友、亲人，可用Yours lovely，Best wishes等；若是一般关系，则用Yours respectfully；若是企业、单位或长者，则用Yours sincerely，后加逗号。
6．签名写在结束语下面一行。除了对熟人或亲友之外，签名应该用全名，并应亲笔签名。 高分策略
1．Thank you very much for your letter. 2．Glad to receive your letter of... 3．I'm writing to ask about... 4．It's very kind of you to write to me. 5．I'm eager to hear from you.
6．Sorry to have written back to you so late. 7．Looking forward to an early reply from you. 8．Please give/send my best regards to your parents. 9．Please remember me to your parents.
