听力原文：M: Hello, Li Min. Come on in, and how've you been keeping recently？
W: Quite all right, thanks, Dr. Francis. How's your project going？
M: Very smoothly. I'm playing a consultant role. I've only been here a month, but I'm already on very good terms with my colleagues in the Department of Computer Science.
W: Dr. Francis, do you know 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. In fact, I've never been to Cambridge. But well, I'm sure I can give you some useful tips. What do you want to know？
W: Things like weather. What's the usual temperature there？
M: The temperature in Scotland is 22, or 23 degrees Centigrade, on average, I think, but Cambridge would be warmer, around 25, because it's down south.
W: That's nice. Where do you think I should live？
M: Oh, that's important. You can live in the college-owned flats, which are often near where you have your classes, and some are 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. I think learning from society is a valuable experience.
W: Yes, exactly, so what's the alternative？
M: Maybe finding an English host family. I know a student Ali from the Middle East. He told me that he had learned a lot by staying with a British family.
W: Thank you, I think it's quite a good suggestion. By the way, Dr. Francis, do you think I could...？
