This story happened in a small mountain village. One day there was an earthquake. Nothing was destroyed
and    1    was hurt. But a huge rock fell from a nearby mountain and stopped in the middle of the road.
     When the earthquake   2    ,  many people came to the road and saw the huge rock. Some of the strongest
men tried to lift the rock    3    the road. But they couldn't move it. They tried to push it but failed. They
tried to    4    it with ropes but nothing worked. "Well," they all agreed, "There is nothing we can do about it.
We'll have to change the    5   ." At this time a boy of 12 years old said, "I think I can help to move the rock."
"You?" they shouted, "What are you talking about?" People all    6    at the boy.
      The next morning some people came into the street. One of them shouted, "The rock is    7    !" More people
ran out to see. It was true. The rock wasn't in the road any more. It wasn't    8    near the road. "This is    9    ,"
they said, "Where did it go?" The boy stood in the street,    10    ," I told you I could move it last night." The boy
walked over to another place. He said, "The    11     is under my feet. I buried (埋葬) it." he said.
     All the people looked    12    . "You see," he said, "I dug a deep hole next to the rock and I dug a small incline
(斜坡) up to the rock and the rock    13    down into the hole by itself. I covered it with earth." The crowds
shouted, "What a    14    boy!" And some of them said, "Why haven't we thought of this good    15    ?"
