     The date was like any other day in his life. After school Bill walked past the shop on the street

corner. He stooped to look at the front row of shoes, and he felt for sorry for himself. He really wanted

to have a pair for his birthday.

     He sadly walked away and thought of what to tell his mother. He knew she would give him anything

if she could. But he also knew very well she had little money. He decided not to go home at once, as he

looked worried and he didn't want to make his mother worry about it. So he went to the park and there

he sat on the grass. Then he saw a girl in a wheelchair (轮椅). He found that the girl moved the wheels

with her hands. Bill looked at her carefully and was surprised to see that the girl had no feet. He looked

down at his own feet. "It is much better to be without shoes than without feet." It was not right for him to

feel so sorry and sad. He went away and smiled, thinking he was more lucky in life.
