撰写英语公文时，遵循一个结构化的方法是非常重要的，这有助于确保内容的清晰和专业性。以下是一个公文英文作文的模板，你可以根据自己的需要进行调整：

引言

以礼貌的问候语和称呼开始，例如 "Dear Mr./Ms. [Last Name]," 或 "Hello [First Name],"，具体取决于你与收件人的熟悉程度。

简要介绍自己或组织，并明确阐述文档的目的。

正文

根据引言中提到的目的，提供详细的信息或解释。

将内容分成段落，每段聚焦于一个具体点或方面。

使用正式语言，避免使用缩略语或口语表达。

通过例子或证据来支持你的观点。

结尾

总结你的主要观点，并可能包括对未来的行动或期望的提及。

以感谢或其他适当的结束语收尾，例如 "Thank you for your attention to this matter." 或 "We look forward to your prompt response."

附件或附录（如有需要）：

如果文档中提到了附件，记得在文末注明 "Attached are the..." 或 "Enclosed is the..."。

```
