Xiao Jie：Haha. No, I won and I felt awesome.
Aunt：Look at you, so pleased with yourself!
Xiao Jie：Of course.
Aunt：Well, do you still want to play table tennis today?

Aunt：Sure. Swimming is good for losing weight. Some people even say swimming a lot can make you smarter.
Xiao Jie：Really? There's a swimming pool at the sports centre.
Aunt：I know. I was there yesterday. I'm going swimming again today.

Xiao Jie：How deep is the water over there?
Aunt：Around two metres. Will you come and try it?
Xiao Jie：I'm not good at swimming. I'm a bit scared about swimming in deep water.
Aunt：How about I buy you a safety ring?
Xiao Jie：I'll have a try first.
Aunt：Xiao Jie, be careful! You're doing just fine.
