     About five hundred years ago, an earthquake (地震) happened in a small village. Luckily for them, nothing

was destroyed (毁坏) and no one was hurt. But a huge stone fell from a nearby mountain and stopped in the

middle of the road.

     When the earthquake stopped, many people came to the road and saw the stone. Some of the strongest men

tried to lift the stone out of the road. But they couldn't move it. They tried to push it but failed. They tried to

pull it with ropes but nothing worked.

     "Well," they said sadly, "there's nothing we can do about it. We'll have to change the way."

     At this time a boy about 12 years old said, "I think I can help you to move the stone away."

     "You?" they shouted. "What are you talking about?" The men all laughed at the boy.

     The next morning, some people came into the road. One of them shouted, "The stone is gone." More people

ran out to see what had happened. It was true. The stone wasn't on the road any longer. It wasn't even near the

road.

     The boy walked over to where the stone had been and said, "I buried it."

     The people looked rather surprised. "You see," he said, "I dug a deep hole next to the stone and I dug a small incline (斜坡) up to the stone and the stone rolled (滚) down into the hole itself. Then I covered it with earth."

     The villagers shouted, "Clever boy! Clever boy!" And some of them said, "Why didn't we think out this good

idea?"
