推荐信是一种礼仪文书，用于向帮助、关心和支持过自己的集体（党政机关、企事业单位、社会团体、科研机构等）或表示感谢的专业书信，有感谢和表扬双重意思。写推荐信既要表达出真切的谢意，又要起到表扬先进、弘扬正气的作用。
一、推荐信的结构与内容
1. 标题
通常在首行正中位置书写“推荐信”三字。
2. 称谓
另起一行顶格书写收件单位的名称或个人姓名，后加冒号。如果是写给个人的信件，应在姓名之后加上适当的称呼，如“尊敬的XXX先生/女士”。
3. 正文
这是推荐信的核心部分，主要包括以下几个正文：
- 开头：简述写信的原因和目的，即为什么要写这封推荐信。
- 主体：详细介绍被推荐人的基本情况、主要成就、优秀品质等。这部分应该具体、真实、生动，避免空洞无物或者过于夸张。
- 结尾：提出希望对方接受你的推荐，并表示愿意提供更多信息或者协助。同时，也可以再次强调被推荐人的优点和潜力。
4. 落款
包括署名和日期。署名应写在正文右下角，日期则写在署名下面。
二、推荐信的格式要求
- 语言风格：推荐信的语言应该正式、礼貌、诚恳，尽量使用书面语而非口语化表达。
- 排版布局：注意段落清晰，每段之间空一行；字体大小适中，易于阅读；整体美观大方。
- 字数限制：虽然没有固定要求，但一般建议控制在一页纸以内为宜。
