Once upon a time there was a little boy who grew in an orphanage（孤儿院）.
The little boy had always wished that he could1 like a bird. It was very2 for him to understand why he could not fly. .
"Why can't I?" he3 . "Is there something wrong with me?"
There was another little boy who had something wrong with his4 . He had always wished that he could walk and run like other little boys and girls.
One day the little orphan boy who had wanted to fly like a bird5 the orphanage. He walked a long way to a6 where he saw the little boy who could not walk or run playing in the sandbox.
He ran over to the little boy and asked him7 he had ever wanted to fly.
"No," said the little boy who could not walk or run. "But I have wondered what it would be like to walk and run like other boys and girls."
"That is very8 ." said the little boy who wanted to fly. "Do you think we could be friends?" he said to the little boy in the sandbox.
"9 !" said the little boy.
The two little boys played for hours. They made sand castles and made really funny sounds with their mouths. The funny sounds made them laugh real hard and10 . Then the little boy's father came with a wheelchair to11 his son. The little boy who had always wanted to fly ran over to the boy's father and whispered（耳语） something into his ear.
"That would be OK," said the man.
The little boy who had always wanted to fly ran over to his12 friend and said, "You are my only friend and I wish that there was something that I could do to make you walk and run like other little boys and girls.13 I can't. However, there is something that I can do for you."
The little orphan boy turned around and told his new friend to slide（滑） up14 his back. He then began to run across the grass. Faster and faster he ran, carrying the little crippled boy on his back. Faster and harder he ran across the park. Soon the15 just went across the two little boys' faces.
