Kitty: Mum, I want a new pair of shoes.
Mum: A new pair of shoes? You have got three pairs.
Kitty: I know, but they are too small and old for me.
Mum: OK. That’s go to the supermarket. (They are in the supermarket)
A shop assistant: What can I do for you?
Mum: I want to buy a pair of shoes for my daughter.
A shop assistant: This pair is very modern, and it is cheap, only seventy yuan. Mum: Cheap? I think it is too dear. Fifty yuan, OK?
A shop assistant: Mmm….OK. Which one?
Kitty: I want the pink pair.
Mum: This pair looks just right. I want this pair of red shoes.
A shop assistant: Here you are.
