四级书信作文的格式【一】
商务英语书信（Business or Commercial English Correspondence）是指交易时所使用的通信，英语书信格式与称谓的差异。在美国，常用Business writing，它包括书信、电报、电话、电传、报告书、明信片等。英语和美语在书信体例方面存在着一定的差异，比如信头和称呼、书信格式、遣词、结尾客套语等均有所不同。
英国书信保守，美国书信有活力。
英国书信较为保守，许多英国人喜欢用老式书信体，用词较为正式刻板，而美国书信语言非常生气、有活力，格式也较为简便。因此当我们写信的对象是英国或其旧殖民地国家时，要使用标准式英语Queens English；如果写信的对象是美国或美国势力范围的地区时，就要用美国英语。当然，英国式的语言文化近年来也有变化，但总体来说，两者间的差异是很明显的。
四级书信作文的格式【二】
Dear Mary,
You said in your letter that many of your classmates wore fashionableclothes, but you couldn\'t afford them so you felt very depressed. There are dif-ferent views on people\'s clothes. The followings are my ideas:
Firstly, you shouldn\'t put too much emphasis on physical appearance.
Remember that the most important task for you today is to concentrate on yourstudies. No matter what you wear, you will really look your best when youcome out first in your examinations.
Secondly, you should understand that it is a fine virtue to live in fru-gality. Just as a famous saying goes, Frugality is the mother of virtue.
Since your family can\'t provide you with enough money to buy fashionableclothes, it is all the more necessary for you to try to lighten the financialburden of your family. And you will find the virtue of frugality benefit youa lot in your future life.
I hope you understand what I mean. Hope you will take a positive attitudetowards life and will be happy again when you read my letter.
Yours,
Anne
