商業(yè)書信通常都非常正式，要求表達一定要非常清晰，否則會給業(yè)務來往造成麻煩。下面是有關(guān)文法的tips，看看你有沒有犯同樣的錯誤哦!

　　1、切忌主客不分或模糊。例子： Deciding to rescind the earlier estimate, our report was updated to include $40,000 for new equipment.應改為 Deciding to rescind our earlier estimate, we have updated our report to include $40,000 for new equipment. (是We來decide,不是report.)

　　2、句子不要零碎。例子： He decided not to audit the last ten contracts, because of our previous objections about compliance.應該連在一起.

　　3、對稱的結(jié)構(gòu)比較容易讓人理解。例子： The owner questioned the occupant’s lease intentions a nd the fact that the contract had been altered with ink markings.應改為: The owner questioned the occupant’s lease intentions a nd ink alterations of the contract.

　　4、單復數(shù)不要搞亂，不然會好刺眼，看著不舒服。例如： An authorized person must show that they have security clearance.

　　5、動詞主詞要呼應。想想這兩個分別： 1). This is one of the public-relations functions that are under budgeted. 2). This is one of the public-relations functions, which are under budgeted.

　　6、時態(tài)和語氣不要轉(zhuǎn)變太多�？瓷虅沼⒄Z已經(jīng)是苦事，不要浪費人家的精力埃

　　7、標點要準確。例如: He did not make repairs, however, he continued to monitor the equipment.改為: He did not make repairs; however, he continued to monitor the equipment.

　　8、選詞要正確，像affect和effect，operative和operational等等就要弄清楚才好用啦。

　　9、拼寫要正確，有電腦拼字檢查功能后，就更加不能偷懶。也許一筆好買賣就因為你的一個錯字飛掉了哦!

　　10、大小寫要注意。非必要不要整個字都是大寫，除非要罵人。例如: MUST change to OS immediately.外國人就覺得不禮貌和喝令人一樣。要強調(diào)的話，用底線，斜字，粗體就可以了。
