If you had to choose one word to describe Kevin,it might be "slow".He didn't learn his ABCs as fast as other kids.He never came first in the schoolyard races.However,his smile was bright and he showed great interest in everything.So when he discovered that Randy was putting together a boy's basketball team,Kevin immediately joined.
At practice,Kevin worked so hard that you'd have thought he was preparing for the NBA.And the whole team truly loved basketball.But just loving the game doesn't help you win.They lost every game that season by a very large margin(差距),except one...that night it snowed and the other team couldn't make it to the game.
At the end of the season,the boys unfortunately played against the 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 time-out."Coach,this is our last game but Kevin has never made a basket.We should let him try," said the boy.With the game completely out of reach,the idea seemed reasonable.So every time Kevin's team had the ball,they would give it to Kevin.His first shot missed and he missed another shot again.This continued a few more times until the player from the other team grew wise.Instead of running off down the court,he threw the ball to Kevin who shot...and missed again.
Soon,all the players were circling Kevin,throwing the ball to him.The whole gymnasium thundered with the clapping,chanting,"Kevin!Kevin!" Finally,after amounts of tries,the ball went in.Kevin's arms shot high into the air and he shouted,"I won!I won!" The first-place team remained unbeaten,but on that evening,everyone left the game truly feeling like a winner.
