A: Lisa, who do you think runs fastest in our class?

B: Is it Jack?

A: Jack runs fast, but I think Mike runs even faster than he does.

B: Oh, you are right! Mike got the first prize in running in the school sports meeting last year.

A: Do you like running?

B: Not really. I think running is kind of boring. I like swimming more.

A: Can you swim well?

B: Yeah, but Harry swims better than I do. Actually I learned swimming from him.

A: I want to learn swimming too, can you teach me?

B: Of course.

A: We can also go play Ping-Pong and play tennis together. I like them very much.

B: That's cool. You play much better tennis than me. I can make progress playing with you.
