在职场中我们有时需要写商务信件，怎样准确地表达英文的商务书信，那是一件非常重要的事。下面群英网就告诉大家写英文商务书信时要注意的十个事项，还不懂怎样写的人可以学一下，懂的人看你会不会犯这种错误。
      1.切忌主客不分或模糊。
例: 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, 不是report.)
      2.句子不要零碎。
例: 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: 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: 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，不要浪费别人的精力。
      7.标点要准确。
例: 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。
      10.大小写要注意。
除非必要不要整个词都大写。例: 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。

说实话,学英语没什么好方法,电视上那些大都没用,开始学英语时,觉得难是正常的,单词要靠记忆,哥有绝招：快速看一下单词,闭眼睛想想它是怎么拼的,如果一下就回忆出来,就记住了,先从短的单词入手,再记长的.单词记住了再组成短语就不难了。实在不行的话，我给你推荐个乐知英语。不错滴，、，有兴趣可以去试听一下他们每晚的免费试听课程，地址: http://www.hiknow.com/sessionhall.html。
