Daming: Have you heard the news?
Betty: What news?
Daming: Lingling and I are doing an English course in LA this summer!
Betty: Oh, really? That’s great! How long will you stay in LA?
Daming: About four weeks. It’s a good chance to practise my English.
Betty: It sure is! But it’s also quite expensive to stay in America for four weeks.
Daming：We are going in a group of 20, and we’ll all stay with different families, so it won’t cost so much.
Betty: That’s good to hear. I hope you have a great time!
