                                                          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  .
     There was only one way to get money,and that was to   7   it.He would have to find a job.
  8  who would 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.
     The day   15   came when James counted his money and found $94.32.He   16   no time and
went down to the 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.
