IV. 便函写作
一、什么是便函
简单地说，便函就是指在同一家机构内从一个人或一个部门传递到另一个
人或部门的书面信息，内容是要在当天或近期内所要办理的事情。
二、便函写作的格式
便函通常包含以下几个部分：
1. 公司名称；
2. 公司的电话号码或传真号码；
3. 收函人姓名（和职位）To:
4. 留言人姓名（和职位）From:
5. 留言日期Date:
6. 便函主题Subject（Re）:
7. 正文
下面我们选择两则便函为例，结合我们刚刚讲到的有关便函的知识，给大家做一个具体的讲解。
例一：
Ace ElectronicsTel/Fax: 0525 228910
22/7/99
To: M. Jones
From: J. BanksI need to hire a car for the day to get me to the exhibition on 14th of next month. Can you book one? You can use my credit card. I don’t think it matters what kind of car it is, but I don’t want to pay more than $45.
例二：
MEMOTo:From:Re: Your enquiry of the 20th October… … … …
II. 便函写作应试技巧
一、题目要求
在考试时，题目中会给你一个特定的情景，同时会告诉给你要完成三项写作任务；题目中会有清楚的字数限制，即40-50字，超出或少于这个字数限制都会影响你的成绩。
二、便函写作的要求
简洁：不用写许多空洞的客套话。内容要直截了当，开门见山。
完整：在用词和造句时要用完整句，不能因为这是一种非正式文体的写作就可以用缩略句，这些做法都是错误的。
实用：写出一条便函、便条、电子短信或留言，一定要有实用性。要少用空泛、含混的概念，而用具体、明确的词汇和句子。交代给对方做的事情或通知对方的内容一定要让对方能够易于操作，准确无误地完成。
以上三点说起来容易，做起来难。下面我们就来演练一下。
