【题目】Einstein often received invitations to explain his theories at different universities. On these trips, his driver was always the same man called Hans. Hans often said to him. “It is a pleasure to drive a talent like you, Dr Einstein.”

One evening, on their way to a university, Einstein said, “I’m so tired. I wish I could refuse to give my lecture(讲座) tonight, Hans, but I don’t want to let my audience down.”

“I know what to do,” said Hans. “I can give the lecture for you. You can trust me. I’ve listened to your lecture so many times that I’ve learnt it by heart. No one knows you at this university, so they won’t find out.”

So, they changed places. At the university, Hans was guided to the front of the hall. Einstein took a seat, listened to Hans give his lecture without difficulty, and joined in the applause (掌声) at the end.

However, before Hans left, a man shouted, “I’d like to ask you a question.” He then asked a difficult question and Hans had no idea what he was talking about.

Einstein turned pale. “Oh no! ,” he thought. “Now we’re in trouble.” But Hans just laughed and said, “That’s such an easy question that even my driver can answer it. Hans, please…”

Einstein stood up and answered the question perfectly.

They left the university, with Einstein driving. A little later, Hans offered to drive. “No, ” laughed Einstein. “It’s a pleasure to drive a talent like you, Hans.”
