Last night was the last game for my eight-year-old son’s soccer team. It was the final quarter. The score was two to one, my son’s team the lead. Parents surrounded the playground, offering encouragement.
With less than ten (remain) seconds, the ball suddenly rolled in front of my son’s teammate, Mickey O’ Donnel. With shouts of “Kick it!” echoing across the playground, Mickey turned around and gave
everything he had. All around me the crowd erupted (沸腾). O’Donnel had scored!
Then there was (silent). Mickey had scored all right,
in the wrong goal, ending the game in a tie. For a moment there was a total hush. You see, Mickey has Down Syndrome（综合症）and for him there is
such thing as a wrong goal. All goals were celebrated by a joyous hug from Mickey. He had even been known to hug the opposing players when they scored.
The silence was finally (break) when Mickey, his face filled with joy, hugged my son
(tight) and shouted, “I scored! I scored. Everybody won! Everybody won!” For a moment I held my breath, not sure how my son would react. I need not
(worry). I watched, through tears, as my son threw up his hand in the classic high-five salute and started chanting, “Way to go Mickey!” Within moments both teams surrounded Mickey, joining in the chant and congratulating him on his goal.
Later that night, when my daughter asked had won, I smiled as I replied, “It was a tie. Everybody won.”
