称呼位于书信开头顶格写，后面用逗号。如果是写给个人，如“Dear Mr. Smith,”“Dear Mary,”；若是写给机构等不明性别对象，常用“Dear Sir/Madam,”。例如，你写信给一位名为 Tom 的朋友询问他的近况，就应该写“Dear Tom,”。注意，称呼要符合人物的身份、年龄、性别等因素，不能随意编造或使用错误称呼。

2.正文（Body）

正文是书信的核心部分，一般分为几个段落来表达不同的意思。通常在正文开始，可以先表明写信的目的或主题。比如，你想邀请同学参加生日聚会，就可以写“I'm writing to invite you to my birthday party.”然后详细阐述相关内容，如聚会的时间、地点、活动安排等，“The party will be held on Saturday evening at my home. We will have a big cake, play some games and watch a movie.”最后可以表达自己的期望，“I'm looking forward to your coming.”正文内容要条理清楚，语句通顺，过渡自然，避免语法和拼写错误，尽量运用一些连接词如“firstly”“secondly”“in addition”等使文章逻辑更清晰。

3.结束语（Ending）

结束语用于结束信件，常见的有“Yours sincerely,”（用于知道对方姓名的正式信件）、“Yours faithfully,”（用于不知道对方姓名的正式信件），或者比较亲切的“Best wishes,”“Love,”等。结束语一般位于正文下方两三行处，后面用逗号。以前面邀请同学聚会的例子来说，如果知道对方的姓名，就可以写“Yours sincerely,”，然后签上自己的名字，如“Li Ming”。

二、常见书信类型及示例

1.道歉信

假如你不小心弄坏了朋友借给你的书，你可以这样写：

Dear [Friend's Name],

I'm writing to apologize for damaging the book you lent me. I was reading it in the garden the other day when our cat jumped onto the table and knocked it into the pool. I know how much this book means to you and I feel terribly sorry. I will either buy you a new copy or have this one repaired and bound properly. Again, please accept my sincere apology. I hope our friendship won't be affected by this incident.

Yours sincerely,

[Your Name]

2.感谢信

当收到叔叔送的生日礼物后，写封感谢信：

Dear Uncle,

I'm so excited to receive the wonderful gift from you! The dictionary is exactly what I need for my English study. It is so thoughtful of you to remember my interest in learning English. Every time I use it, I will think of your kindness and encouragement. Thank you very much and I wish you good health and a happy life.

Yours lovingly,

[Your Name]
