Subject：Don’t try to do a number on me.

A: I have finished my homework already. May I do some surfing?

B: How did you finish it in such a short time? Don’t try to do a number on me.

你怎么可能在这么短的时间写完呢？不要玩手段欺骗我。

地道表达：do a number on sb.

1. 解词释义

Do a number on sb.是什么意思呢？我们通过下面这个例句来推敲它的意思。The man who came to fix my roof certainly did a number on me. He said he’d do the work for fifteen hundred dollars but when he finished, he charged me more than three thousand! 这句话的意思是：来为他修屋顶的人起先开价1500美元，但是完工后要他付三千美元，比原来多了一倍，可见这人是纯心欺骗他的。在这个例子里did a number on me就是“玩弄手段欺骗人”的意思。其英文解释为：to damage or harm someone or something。如果我们想警告那些玩弄手段欺骗我们，就可以这样说：“Don’t do a number on me.”

2. 典型范例

e.g. Why did she do a number on John?

她为什么蓄意侮辱约翰呢?

e.g. The teacher did a number on the whole class by giving them a pop quiz.

e.g. I'm not surprised Caroline doesn't like him. He really did a number on her at work.
