Kevin was a “slow” boy. He didn’t learn his ABCs as fast as other kids. He never came in first in the schoolyard races. However, Kevin could get along well with other people. And his enthusiasm for life was quite contagious (有感染力的). So, when he discovered that his teacher, Randy Moss, was putting together a basketball team, his mother could only answer, “Yes, you may join.”
Basketball became the center of Kevin’s life. He liked to stand in a certain spot near the free-throw line and shoot baskets. Patiently, he stood there throwing ball after ball.
The day before their first game, Randy gave each player a bright red jersey (运动衫). Kevin had stars in his eyes when he saw his number 12. He quickly put it on and almost never took it off again. Kevin and his whole team truly loved basketball. But just loving the game doesn’t help you win. More balls fell out of the basket than into it, and the boys lost every game that season, except one—the night it snowed. and the other team couldn’t make it to the game.
At the end of the season, they had the misfortune to play against the first-place team-the undefeated first-place team. The game went pretty much as expected, and near the middle of the fourth quarter Kevin’s team stood nearly 30 points behind.
At that point, one of Kevin’s teammates called a time-out. As he came to the side, Randy couldn’t imagine why the time-out had been called. “Mr. Moss, this is our last game and I know that Kevin has played in every game, but he’s never made a basket. I think we should let Kevin make a basket,” said the boy.
With the game completely out of reach, the idea seemed reasonable, so the plan was made. Every time Kevin’s team had the ball, Kevin was to stand in his special spot near the free-throw line and they would give him the ball.
His first shot bounced around but missed.
Soon, all the players threw the ball to Kevin and clapped for him.
