Once Einstein travelled all over America, and gave lectures everywhere. His driver always listened to his lecture. One day, the driver told Einstein that he knew the lecture so well taht he could give it himself. Einstein agreedwith a smile.

That evening they both came to the lecture room. Nobody there had seen Einstein before, so the driver began the lecture. Sure enough he didn't make any mistakes. The lecture was well done, and the people's clap lasted a long time.

But just they got to the door, a man suddenly asked the driver a difficult question. The driver listened carefully, and pointed to Einstein,"This question is so easy that you may ask my driver."

爱因斯坦曾周游美国，到各地去讲学。他的司机总是听他的讲座。有一天司机告诉爱因斯坦说他通宵了爱因斯坦的讲座，他也能讲。爱因斯坦笑着同意了。

那天晚上他俩进入了讲演厅。没有人以前曾见过爱因斯坦，所以司机开始讲开了。千真万确，他没有出任何错。讲演很成功，人们的掌声持续了很久。

可是就在他们走到门口时，有人突然问司机一个难题。司机认真的听了这个问题后，指着爱因斯坦说：“这个问题太简单了，你可以问我的司机。”
