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.应改为 Deciding to rescind our earlier estimate, we have updated our report to include $40,000 for new equipment. (We决定呀, 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. 两个句子应该连在一起：He decided not to audit the last ten contracts because of our previous objections about compliance.

3.结构对称,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. 应改为: The owner questioned the occupant's lease intentions and ink alterations of the contract.

4.单复数不要搞乱，不然会好刺眼，看着不舒服。
例如: An authorized person must show that they have security clearance. 应改为 Authorized persons must show that they have security clearance.

5.动词和主语要呼应。
想想这两个句子的分别: 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.时态和语气不要转换太多。
看商务英语已经是苦事，不要浪费人家的精力啊。

7.标点要准确。
例如: He did not make repairs, however, he continued to monitor the equipment. 应改为: He did not make repairs; however, he continued to monitor the equipment.

8.选词正确。
像affect和effect，operative和operational等等就要弄清楚才好用啦。affect用作动词的时候，意为“影响”，相当于have an effect on，并且，这个影响一般是指不好的影响，如：The climate affected his health.(气候影响了他的健康。)至于effect，一般用作名词，若用作动词，其意为“招致，引起”。总之，要多多积累同义词的辨析，注意词义及表达色彩。

9.拼写正确。
犯单词拼写等低级错误很容易给人造成一种不好的感觉，觉得你写信的时候不够认真，态度不够诚恳。

10.大小写要注意。
除非必要不要整个词都大写，除非要骂人。例如: MUST change to OS immediately. 外国人就觉得不礼貌和喝令人一样。
