(Tom and Bob are walking on the street now. They want to go to a bookshop. ) 
Bob: Look, the plane model is really good.

Tom: Yes. It's beautiful and shining.

Bob: You don't look very well, Tom. You are so quiet.

Tom: I don't feel good. I have a stomachache.

Bob: Is it serious?

Tom: No. I think I eat too much this morning.

Bob: You should take care of yourself.

Tom: I feel much better now. Let's go to the bookshop.

Bob: You should take some medicine. There is a chemist's store.

Tom: I don't want to take any medicine. Look! There is an ice cream shop.

Bob: Tom, ice cream is bad for you!

Tom: It doesn't matter.

…

Tom: Bob, I have a bad stomachache.

Bob: Let me take you to the hospital.

Tom: Thank you, Bob. I won't eat any ice cream.
