在考研英语的备考过程中，写作部分无疑是一个重头戏。特别是书信类作文，不仅考查学生的英语表达能力，更考查其对不同场合下书信格式的掌握程度。本文将通过一篇范文来详细解析考研英语中书信类作文的格式及注意事项。
一、书信类作文的基本格式
1. 信头（Heading）
信头包括写信人的姓名、地址以及日期。这些信息应写在信的第一页的右上角。具体格式如下：
Your Name
Your Address
City, State, ZIP Code
Date
2. 称呼（Salutation）
称呼是对收信人的一种礼貌称谓，一般位于信纸左边，比信头低两行。常见的称呼有Dear Mr./Ms. [Last Name]，Dear Professor [Last Name]，或者To Whom It May Concern等。
3. 正文（Body）
正文是信件的核心内容，通常分为引言、主体和结尾三个部分。每个段落应围绕一个中心思想展开，并保持段落间的逻辑连贯性。
4. 结束语（Closing）
结束语用于表示信件即将结束，常见的有Sincerely, Yours faithfully, Best regards等。结束语后应加上逗号。
5. 签名（Signature）
在结束语下方留出几行空白，然后签上自己的名字。如果是打印的信，可以在打印名字上方再签上自己的手写签名。

Li Hua
No. 34, Nanhu Road, Chengdu, Sichuan Province, China
June 20, 2023
Dear Professor Smith,
I am writing to apply for participation in the upcoming International Conference on Environmental Science scheduled to be held in New York from July 15th to July 20th, 2023.
As a postgraduate student majoring in Environmental Science at Sichuan University, I have been actively involved in several research projects related to environmental conservation and sustainable development. My academic background and research interests align closely with the themes of this conference, and I believe that attending this event would greatly benefit my professional development.
I am particularly interested in the sessions on “Climate Change Mitigation” and “Biodiversity Conservation,” as they are directly relevant to my current research project on the impact of climate change on biodiversity in the Sichuan Basin. By attending these sessions, I hope to gain new insights and establish valuable connections with experts in the field.
Enclosed with this letter are my resume, a copy of my academic transcript, and a brief outline of my research project. I would be grateful if you could consider my application favorably and provide me with the opportunity to contribute to and learn from this prestigious event.
Thank you very much for your time and consideration. I look forward to your positive response.
Sincerely,
Li Hua
