     "Everything happens for the best," my mother said whenever I faced disappointment. "If you can   1  
on,
one day something good will happen. And you'll realize that it wouldn't have happened if not for that   2  
disappointment."
     Mother was right, as I discovered after graduating from college. I had   3   myself for a sports
announcer(播音员). So I went to Chicago and knocked on the door of every station and got   4   every
time.
     In one station, a kind lady told me that   40   stations wouldn’t risk employing a person without   5  
since I had just graduated. "Go out in the town and find a small station that might give you a chance,"she
said.
     I returned to Dixon,   6   I had finished my high school education and had   7   in the school football
team. My father said that our town had opened a store and wanted a local athlete to   8   its sports
department. The job sounded just   9   for me but I wasn’t hired.
     My   10   had shown as if by design. "Everything happens for the best," Mum   11   me. Dad offered

hired a/an   12  .   13   I left his office, my frustration boiled over(发怒). I asked aloud, "  14   can a fellow
get to be a sports announcer if   15   can't get a job in a radio station?"
     Suddenly, I heard the director   16  . "What was that you said about sports? Do you know anything
about football?" Then he stood me before a microphone and asked me to   17   an imaginary game.  
     It was easy, and I did it without difficulty. The director was   18   and told me I would be broadcasting
a game on the   19   Saturday.
