作文题目： You are the office manager at an insurance company. You have arranged for contractors to upgrade your computer system. This means the system will be shut down for a full day. Write a memo of 40-50 words: informing staff of the shutdown telling them when it will happen asking them to prepare alternative work for the day. 老师提示： 商务写作中遵循的原则是：简洁，精确，礼貌。在考试中或者工作中，格式 基本已经 给出， 所以只需要我们写正文即可。 正文中我们写作要做到选词精当， 一针见血，语法正确，不出低级错误的句子。备忘录属于半正式的文体写作，所 以在句子选择 上可以适当放宽，不必太正式。 网友作文一： MEMORANDUM from : Tom TO : all staff date : 25/8 Because our computor system will be upgraded by the contractors on 28 AUGUEST, so the system will be shut down for a full day on that day, i ask for you prepare alternative work for the day. and the work don't use computer system . I think you can give a good performance to me to pass the accident.  名师修改意见： Business writing 中尽量少使用 because....so... 这样的结构，看起 来不够专业，改为：As we plan to upgrade.....
有中式英文的痕迹： 我要求你们。 。 改为： 。。 please prepare alternative work if you have to use the computer. 这不能算作 accident, 既然已经计划好了。整句去掉。换成 thank you. 网友作文二： From: office manager To: all staff Subject: the company system I would like to notify you that the computer system of our company's will be shut down on this Tuesday for a whole day long on account of the system needs a upgrade.Therefore, please taking notice of this event in advance, in case of some potential inconveniences and troubles on Tuesday, yet prepare alternative work for that day.  Thank you. 名师修改意见： 去掉这个开头，直接用被动语态开头。 去掉，多余了。 如果你不能保证用长复句可以表达清楚，那么建议换成短句吧。拆成几 个短句也许表达更贴切呢。 这句话看起来非常不清楚，主语在哪里?please 的后面是吗?改成： please make sure that you have prepared alternative work. 另换一行 网友作文三： Dear all: The file system will shtudown due to system maintainance next Friday. It will take a full day to finish this job. Please do not acccess the file server that day and backup your files one it.
名师修改意见： 够干练了，语法错误多。 Be shut down 去掉 Access to On it? 网友作文四： From: office Manager To: all staff Subject: upgarde of computer system As our computer system need to be upgraded, we have arranged the contarctors to upgrade the them on Wedesday. On that day all computers should be shutted down for a full day, so you need arrange some alternative work for that day. 名师修改意见： 第一: 不要重复使用前面已经用过的词;第二：指代错误，前面说的 system 是单数，怎么到这里变成了 them? 合成一句：as we have arranged the contractor to upgrade our computer system.
