• 1. 

  N-SING If you describe a situation as a Catch-22, you mean it is an impossible situation because you cannot do one thing until you do another thing, but you cannot do the second thing until you do the first thing. 相互矛盾的困窘 [oft N n]

  例：

  It's a Catch-22 situation here. Nobody wants to support you until you're successful, but without the support how can you ever be successful?

  这就是一个相互矛盾的困窘。没有人想要支持你除非你已经成功了，但是如果没有人支持，你怎么可能成功呢？
