Canteen录音原文提到，计算机中心位于左侧角落的图书馆(Library)与右边的餐厅(can-teen)之间。图书馆位于左边角落，因此右侧20空所在区域为餐厅(canteen)。

M: Well, can you tell me where the Computer Centre is? In the main campus?
W: Do you have a campus map?
M: No.
W: Well. I will draw a map for you. Do you have a pen?
M: Yes.
W: Well, this is the entrance, and the first building you can see is the Teaching Building.
M: Yes. W: On your left is a small bookstore of our university.
M: Great. I just want to buy some books and CDs.
W: Then, go north, and you can see a small gym opposite the bookstore.
M: A gym? Does it have a tennis court?
W: Sorry, I don’t know.
M: Fine.
W: On the other side is the Student Union. And there is a lab on the east side of it.
M: If I want to join some societies I can go to the Student Union, right?
W: Right.
M: Oh, does the campus have a parking lot?
W: Yes. It is near to the lab and not far from the Teaching Building.
M: Great. How about the parking fee?
W: Sorry, I’m not sure, maybe five pounds per hour.
M: OK. And where is the Computer Centre?
W: It is opposite to the Student Union between the Library on the left corner and the canteen on your right.
M: OK. Thank you very much.
W: Good luck.
