书信邮件是中考高考作文的固定题型：格式有模板、语气有套路、每段有分工。结构记熟之后，剩下的就是把要点「装」进固定框架，又快又稳。这篇给足全套模板句。
三段式结构模板
| 段落 | 功能 | 常用句型 |
|---|---|---|
| 开头段 | 自我介绍 + 写信目的 | I am Li Hua, ... I am writing to invite you to ... |
| 主体段 | 分点展开要点 | First ... Besides ... Finally ... |
| 结尾段 | 期待回复 + 致谢祝福 | I am looking forward to your reply. |
六类书信高频套句
- 邀请信：We would feel much honored if you could come. The activity will start at ... in ...
- 感谢信：I am writing to express my thanks for your help. / But for your help, I couldn't have made it.
- 建议信：I would like to suggest that ... / It would be a good idea to ...
- 道歉信：I am terribly sorry for not ... / Please accept my sincere apology.
- 申请信：I am writing to apply for the position. I believe I am suitable for it because ...
- 咨询信：I would like to know more about ... / I wonder if you could tell me ...
格式规范：称呼 Dear ... 顶格加逗号；正文首行缩进或空行均可，全卷统一；落款 Yours, 加名字写在右下角。字数一般 80 到 120 词，写到下限加一两句最保险。
易错点：look forward to 后接 doing
结尾万能句 I am looking forward to your reply 几乎人人会写，但换成动词就大面积出错：look forward to hear from you 是错的，必须写 hearing from you——这里的 to 是介词。判断方法记住介词 to 名单：look forward to、be used to、pay attention to、devote ... to 后面一律接 doing。写作前自查一遍这四个短语，等于保住结尾段的基本分。另外落款不要用真实姓名，题目指定 Li Hua 就写 Li Hua，格式和内容一样计分。
