英語幽默笑話：四減四等于幾?

One day, the teacher inquired Peter: "How much is four minus four?" Peter was tongue-tied.

The teacher got angry and said: "What a fool! You see, if I put four coins in your pocket, but there is a hole in your pocket and all of them leak out, now what is left in your pocket?"

"The hole." replied Peter.

四減四等于幾?

一天，老師問彼得：“4減4等于幾?”彼得張口結(jié)舌答不上來。

老師生氣地說：“真笨!比如我給你衣袋里裝進(jìn)4個(gè)硬幣，可你衣袋上有個(gè)窟窿，硬幣全從這里漏掉了，那么，你衣袋里還剩下什么?”

“還剩下個(gè)窟窿。”彼得答道。
