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(shuō):"你們已了解 ‘ 謊言 ' 的概念,關(guān)于這個(gè)問(wèn)題,我已在自己的著作《論謊言》一書(shū)中寫(xiě)到。你們誰(shuí)讀過(guò)這本書(shū),請(qǐng)舉起手來(lái)。"所有的同學(xué)都不約而同地舉起了手。
教授繼續(xù)說(shuō):"很好,這回可有了新的講課例子,我寫(xiě)的書(shū)還沒(méi)有出版呢!"
