                                                                  James's New Bicycle
     James shook his money box again. Nothing! He carefully   1   the coins that lay on the bed. $24.52 was all
that he had. The bicycle he wanted was at least $90!   2   on earth was he going to get the   3   of the money?
     He knew that his friends all had bicycles. It was   4   to hang around with people when you were the only
one without wheels. He thought about what he could do. There was no   5   asking his parents, for he knew
they had no money to   6  .

hire him and what could he do? He decided to ask Mr. Clay for advice, who usually had   9   on most things.
     "Well, you can start right here," said Mr. Clay. "My windows need cleaning and my car needs washing."
     That was the  10  of James's odd-job (零工) business. For three months he worked every day after finishing
his homework. He was amazed by the  11  of jobs that people found for him to do. He took dogs and babies for
walks, cleared out cupboards, and mended books. He lost count of the  12  of cars he washed and windows he
cleaned, but the  13  increased and he knew that he would soon have  14  for the bicycle he longed for.

shop to pick up the bicycle he wanted. He rode  17  home, looking forward to showing his new bicycle to his
friends. It had been hard  18  for the money, but James knew that he valued his bicycle far more  19  he had
bought it with his own money. He had  20  what he thought was impossible, and that was worth even more than
the bicycle.
