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. (We決定呀, 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. 兩個句子應該連在一起：He decided not to audit the last ten contracts because of our previous objections about compliance.
3.結構對稱,令人容易理解。
例子: The owner questioned the occupant's lease intentions and the fact that the contract had been altered with ink markings. 應改為: The owner questioned the occupant's lease intentions and ink alterations of the contract.
4.單複數不要搞亂，不然會好刺眼，看著不舒服。
例如: An authorized person must show that they have security clearance. 應改為 Authorized persons must show that they have security clearance.
5.動詞和主語要呼應。
想想這兩個句子的分別: 1. This is one of the public-relations functions that is under-budgeted. 2. This is one of the public-relations functions, which are under-budgeted.
6.時態和語氣不要轉換太多。
看商務英語已經是苦事，不要浪費人家的精力啊。
7.標點要準確。
例如: He did not make repairs, however, he continued to monitor the equipment. 應改為: He did not make repairs; however, he continued to monitor the equipment.
8.選詞正確。
像affect和effect，operative 和operational等等就要弄清楚才好用啦。affect用作動詞的時候，意為“影響”，相當於have an effect on，並且，這個影響一般是指不好的影響，如：The climate affected his health.(氣候影響了他的健康。)至於effect，一般用作名詞，若用作動詞，其意為“招致，引起”。總之，要多多積累同義詞的`辨析，注意詞義及表達色彩。
9.拼寫正確。
犯單詞拼寫等低階錯誤很容易給人造成一種不好的感覺，覺得你寫信的時候不夠認真，態度不夠誠懇。
10.大小寫要注意。
除非必要不要整個詞都大寫，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。
