　　Susan： Yes. I have sports every afternoon.

　　David： Do you often go swimming?

　　Susan： Yes, I go swimming once a week.

　　David： I used to swim at middle school, but I don’t have time any more.

　　Susan： That’s too bad! Exercise is very important.

　　David： I know. I am getting fat, you see. Anyway, I don’t want to be heavy.

　　Susan： Well, I’m going to swim this afternoon. Do you want to go with me?

　　David： OK! I really need more exercises. When and where shall we meet?

　　Susan： How about three o’clock, at the swimming-pool?
