between New Rochelle and Yonkers High. New Rochelle was coached by Dan O'Brien, Yonkers by Les Beck.

and   6   contested. Yonkers was   7   by one point as I   8   the clock and discovered there were only 30
seconds left to play.

ball   10   around the rim and off. The fans shouted with disappointment.

The noise of whistles, screams and shouts was   12  . I took a quick look at the clock and saw that the game
was over. I hadn't heard the final buzzer (终场哨声) because of the noise. I  13  with the other official, but he
could not help me.

the buzzer   15   as the ball rolled off the rim,  16   the tap-in was made."  
     I was in the unpleasant position of having to tell Coach O'Brien the   17   news."Dan," I said, " Yonkers won
the game."  
     His face clouded over. The young timekeeper came up. He said, "I'm sorry, Dad. The time ran out before the
final basket."  
     Suddenly, Coach O'Brien's face  18  . He said, "That's okay, Joe. You did what you had to do. I'm  19   of
you."  
     Turning to me, he said, "Al, I want you to meet my   20  , Joe."  
     The two of them then walked off the court together, shoulder to shoulder.
