       The sun was shining as Kevin walked to the old bench(长凳) where he met Mike every afternoon

after school. They were good friends and loved to play football. They didn’t have enough money to buy

a real football, but Mike had made a ball out of old socks covered with a piece of plastic. It wasn’t

beautiful, but it worked well. The two friends didn’t stop kicking and running until very late.

       The next afternoon, Mike and Kevin met again at the old bench. Soon the home-made ball was

spinning(旋转) across the grass as the boys laughed and shouted happily. The ball was stopped by a

boy wearing a nice pair of sneakers(运动鞋). Kevin was upset when he saw it was Steven.

      The next morning, Kevin’s mother gave him an envelope(信封). “Your uncle sent you a birthday

present,” she smiled. Kevin’s eyes grew big when he saw the $100 bill. Later that day, a pair of new

sneaker lay next to his chair, and in the corner, a real football.

      The next afternoon, Steven invited Kevin to play football on the field next to the library. Steven did

not want Mike to join them only because Mike’s sneakers were dirty and he was not good at football.

When the game was over, Kevin and Steven walked past the old bench where Mike was sitting. Steven

picked up a stone and threw it at him. Kevin, holding his new football in his hands, walked on and did

not look back.

     One afternoon, as Kevin walked past the old bench, he saw something lying under it. He looked

closer and saw it was the home-made ball. Kevin was full of sorrow at the sight of his old home-made

ball, and he let out a sad sigh(叹气). As his sadness turned to anger, he picked up his new football and

kicked it into the air. Kevin kicked it so hard that it flew past the library and over the school gate. Then

Kevin walked to the bench and picked up his home-made ball. Holding it in his hands, Kevin sat down

and waited.
