A professor said to the class,"You have learnt the concept of lies. In my book On Lies I have discussed this concept. Please raise your hand if you already read this book." All the students raised their hands together.
The professor continued,"Very good. Now I have a new example for my lecture! My book hasn't been published yet!"
教授說:"你們已了解 ‘ 謊言 ' 的概念,關(guān)于這個問題,我已在自己的著作《論謊言》一書中寫到。你們誰讀過這本書,請舉起手來。"所有的同學都不約而同地舉起了手。
教授繼續(xù)說:"很好,這回可有了新的講課例子,我寫的書還沒有出版呢!"
