这是萧伯纳--George Bernard Shaw的名言
英文原文：If you have an apple and I have an apple and we exchange apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.--George Bernard Shaw
中文翻译：我有一个苹果，你也有一个苹果，假如我们互相交换的话，我们各自还是 都有一个苹果；但如果你有一种思想，我也有一种思想，我们再进行交换的时候，我们就会 各自同时拥有两种思想。
