商务来往中，当然少不了书信的写作，那么在商务书信写作中有什么需要注意的地方呢?来看看吧。
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.
2. 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.
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. 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.
5. 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.
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。
9. 拼字正确。
有电脑拼字检查功能后，就更加不能偷懒。
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。要强调的话，用底线，斜字，粗体就可以了。
