在商务英语使用的过程中，信函是比较常用的一种沟通方式，但是很多人的写作技巧都不行。今天我们就为大家整理了BEC商务英语信函写作技巧，希望对大家有所帮助。
(一) 避免使用陈旧的商业术语
陈旧的与传统的商业术语(Commercial jargon)对信的内容没有什么作用，应该避免使用。
例一： Wordy: We wish to acknowledge receipt of your letter of November 14 with the check for Stg.10 enclosed and wish to thank you for same. Concise: We appreciate your letter of November 14 and the check for Stg. 10 you sent with it.
例二： Wordy: We take liberty to approach you with the request that you would be kind enough to introduce to us some exporters of cotton textiles in your cities. Would you please introduce to us some exporters of cotton textiles in your city? Concise: (a) Please introduce to us some exporters of cotton textiles in your city. (b)Would you please introduce to us some exporters of cotton textiles in your city. (注：此类简洁的表达方式很多。)
(二) 要长话短说，避免罗嗦
通常商业人士每天需要阅读大量的书信，对开门见山，长话短说，直接切题的信特别欢迎。因此， 写信要力求长话短说，
例如：不要写 应写作 Please see that an enquiry is conducted to determine the reason. Please find out the reason. We express our regret at being unable to fulfill your order on this occasion. We are sorry we cannot meet your present order. 要使用简洁的语言，有可能的话， 尽量使用单词来代替某些娇柔做作的短语。
删去不必要的形容词，如下列句子中的形容词或副词删去后并不影响句子的原意： The proposal is under (active) consideration. The answer is (definitely) correct. I would (rather) think the fare is too high. The (true) facts are as stated.
(三) 要注意每句句子的长短
例如："We would like to know whether you would allow us to extend the time of shipment for twenty days, and if you would be so kind as to allow us to do so, kindly give us your reply by cable without delay." 这句话过分"客气"，使句子过长而不清楚。内容要求对方同意延期交货20天，一般情况下，应尽可能提出延期到那一天的具体日期。这句话可压缩为："Please reply by telegram immediately if you will allow us to delay the shipment until April 21."(如同意我们把交货延期到四月二十一日，请电复。)
有的作者为了使人们记住避免使用陈旧的商业术语，专门选择了一些他认为陈旧的商业术语搞成一首诗： We beg to advise and wish to state That yours has arrived of recent date. We have it before us, its contents noted; Herewith enclosed are the prices we quoted. Attached please find, as per your request, The data you wanted; and not let us suggest Your order be sent, and not held unduly, We beg to remain, yours most truly.
COURTESY译成"礼貌"。但是根据西方国家函电书籍作者普遍的看法，所谓COURTESY是"客气而又体谅人"的意思。有的作者还把 COURTESY和POLITENESS这两个同义词做了比较，认为：POLITENESS的客气只是表现在文章的语句上，而COURTESY则表现在对对方的"体谅"，例如：
a) We have received with many thanks your letter of Oct.7, and we take the pleasure of sending you latest catalog. We wish to draw your attention to a special offer, which we have made in it. [polite]
b) you will be particularly interested in a special offer on page 5 of the latest catalog enclosed, which you requested in your letter of Oct. 7.
You ought to Perhaps you could…… Your letter is not clear at all; I can't understand it. If I understand your letter correctly... Obviously, if you'd read your policy carefully, You'd be able to answer these questions yourself. Sometimes policy wording is a little hard to understand glad to clear up these questions for you. [courtesy]
