One day, a student was talking with a professor (教授), who’s kind to those who waited on his  小题1: .    

As they went along, they saw a pair of old shoes 小题2:  on the path (小路), which, they supposed, belonged to a poor man working in a nearby field (田地). He had neatly finished his小题3:  work.

The student came to a stop, and said to the professor, “Let’s play a hoax on the man: we hide his shoes, hide ourselves and wait to see how 小题4: he would be when he finds that his shoes are   小题5: .”

“My friend,” answered the professor, “We should never enjoy ourselves while making the poor sad. Now you are rich, why not give yourself a much greater 小题6:   by helping the poor man? Put a coin into each shoe, hide ourselves and see what will happen to him.”

The student did so, and they both places themselves behind the nearby trees.

After finishing his work, the poor man came across the field to the path. Putting his foot into one of his shoes, he felt something unusual. He took off his shoes and stopped 小题7:  what it was and he found the coin.

He took out the coin, surprised, and looked at it    小题8: for a while. Then he looked around, but   小题9:was there. Then he started to put on the other shoe. He got much more surprises when he found the other coin.

The poor man then looked up into the sky and shouted “Thank You!” The student stood there with tears (眼泪) in his eyes. “Now,” said the professor, “Aren’t you more pleased than if you had played  小题10:   planned hoax?”

“You’ve taught me a lesson which I will never forget,” answered the student.
