M: Hello, Li Li. Come on in. How’ve you been keeping recently?
W: Quite well Thanks. How’s your project?
M: Great. I’m playing a consultancy role. I’ve only been here in China for a month, but already on very good terms with my colleagues in the Department of Computer Science. Well, sit down, please.
W: Dr. Francis, I’ve got a chance to go to Cambridge in August. I wonder if you could tell me something about Britain.
M: Certainly. Well, I was actually brought up in Scotland. But I’m sure I can give you some useful tips. Now, what do you want to know?
W: Things like weather. What’s the temperature there?
M: The temperature in Cambridge is warmer than Scotland, around 25, because it’s down south.
W: That’s nice. Do you know it’s 34 here? By the way, where do you think I should stay?
M: Well, you can, I suppose, stay in the college-owned flats, which are often near where you have your classes, or even on the campus. That would certainly be convenient.
W: Yes, it would.
M: But it can also be a disadvantage because you are, in a sense, separated from ordinary society, and I think learning from society is a valuable experience.
W: So what’s the alternative?
M: Maybe finding an English host family. I know of a student Ali. He told me that he had learnt a lot by staying with a British family.
W: Thanks. It’s quite a good idea.
