本期作文题目：
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。

名师修改意见：
[1]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.....
[2]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.
[3]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：

Thank you.[5]
名师修改意见：
[1]去掉这个开头，直接用被动语态开头。
[2]去掉，多余了。
[3]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。
[4]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.
[5]另换一行

名师修改意见：

Subject: upgarde of computer system
As our computer system need to be upgraded, we have arranged the contarctors to upgrade the them [1]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：
[1]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.
