You got me. 你问倒我了.
当别人问了你一个问题,而你却不知道答案的时候,你就可以说 you got me:
A:When did the Tang Dynasty end? 唐朝是什么时候结束的?
B:Umm….. you got me! 嗯……你问倒我了!
这句话在使用上的另一个时机是,当你做一些不想让人知道的事,却不巧被发现,这时你也可以说You got me.“你逮到我了。”
A:Didn't you say you were at home all day yesterday? 你不是说你昨天整天都在家吗?
B:That's right. 对啊!
A:Liar! I saw you with your girlfriend at the mall!
骗子!我看到你跟你女朋友在购物中心里!
B:Whoops! You got me! 糟糕!被你逮到了。
