Lingling: Mum, my coat is too small. I want a big one.
Mum: OK! Let's go to the supermarket.
Lingling: This pink coat is big and nice.
Mum: But it's too expensive. This yellow one is lovely and cheap. Look! It's got a monkey on it.
Lingling; But I don't like yellow.
Mum: Look at this purple one. It's big and nice too. And it's cheap. Do you like it?
Lingling: Yes. I like it very much. May I try it on?
Sales assistant: Sure. Here you are.
Mum: Great! We'll take it.
