Misha: Hi, guys. Do you need a player? Jim: Yes, we do, but we don't need you! Mark: Stop it, Jim. He is our last chance. Jackson has broken his arm, Andrews has caught a cold, Graham has left the school and Black has joined the choir. Jim: Why did he do that? Mark: He went there with his best friend Kate Small. Ha-ha-ha! Jim: It isn't funny. He was our best forward. Last year he scored three goals. And now he's not with us! Misha: Is this match very important? Mark: It's the final. All our team worked really hard for it last year. In March we beat the Bears. The score was 2-1. Then we played with the Sharks and they lost one-three. In April we played with the Foxes. The game ended in a draw: 3-3. So tomorrow is the most important match of the year. Misha: If you give me a chance, I can try to help. Jim: Have you ever played football before? Misha: Yes, I have. It's my favourite game. Jim: OK, Inin, you are in the team. We have no time to train you. The match is tomorrow morning. You'll be a defender. Try to help our goalkeeper, that's all you have to do. Misha: Don't worry, I will. Mark: See you tomorrow. Misha: Bye!
