听力原文：M: Hi, Vivian. What are you doing here？

W: Hi, Steve. I'm having a bit of trouble finding some of the stuff t need.

M: What' re you looking for？

W: Well, I'm just trying to find out something about the use of steel in building construction. Do you have any idea？

M: Frankly, I don't know much about this. What about the library？ There's a database on the computer, and most of the stuff you need is catalogued. You can find it somewhere.

W: Yes, but that' s the easy part ! Then you have to find the book you want on the shelves, and you often find that it' s out already.

M: I know what you mean! Then you have to line up to borrow it, ff it's CTL.

W: CTL？ What's CTL？

M: It means "confined to library": you know, it means you can' t take it out. You have to read it in the library.

W: It seems easy, doesn' t it？ But you have to reserve it, and then you may want to photocopy bits of it, or make notes and there never seems to be enough time.

M: Hmm! In your shoes, I think I' d have a word with our tutor.

W: I think I'll do that! Thanks! See you later. Bye!

M: See yah! And good luck!
