名师点评网友BEC初级作文(2)

网友作文五：
To: All staff
From: Sarah Buffay
As you all know, there is an increasing dispute about smoking in the office. Now we'd like to formulate a policy both fair to smokers and nonsmokers: The vacant room 408 will be opened as "Smoking Room" from tomorrow. All smokers may go there within the time limitation from 9:00a.m. to 4:00p.m. But smokers are not allowed to smoke outside this room.[1]
If you have any problems, please contact me. [2]

名师指导：
[1]去掉。
[2]这是信件的结尾，不是memo的，直接用 thank you 就可以。
