同事忘了你交待的事情？有必要提醒他一下了。怎么提醒好呢？看看下面的对话吧。

A: Terry? I need the file you took yesterday.
特里，我要用你昨天拿走的文件。 

B: I'm sorry, Jane. I left it at home. I'll bring it back tomorrow.
对不起，简。我把它忘在家里了，明天给你拿来。

A: Terry, I told you yesterday that I'd be using the file this afternoon.
我昨天告诉你我今天下午要用的。 

B: I know, Jane. I just walked out and it completely slipped my mind. I'll go home and get it at noon, all right?
我知道。我完全忘了这回事了。我中午回家去取，行吗？
