听力原文：M: Holly, is it possible to borrow your notes？ I'll return them tomorrow.

W: Sorry, but I usually go to the cafeteria and review them. Say, how about copying them over in the library？

M: OK. I think I've got enough coins for the machines.

W: No problem. But I don't understand why you need my notes, Carter; you haven't missed any classes.

M: Weekday mornings, I'm a cashier at a coffee shop downtown. After work, I come directly to school!

W: Wow, you're probably exhausted!

M: That's exactly why I want to borrow your notes. I've been nodding off during class, so my notes aren't very good.

W: Well, here's Professor Lahelle. How are you feeling？

M: I'm usually awake at the beginning. But after thirty minutes into class, I'm having trouble keeping my eyes open.

W: Listen. I need someone to study with, and you need someone to keep you awake; want to be study partners？

M: Yeah, I'd sure appreciate it.

W: OK, let's start today at the library. We're going there anyway, and I don't have to go to the cafeteria.

M: Sounds good. Oh, no, it looks like he's brought along some more of his slides; elbow me if I start drifting off.

W: I'm afraid I Won't be very helpful. His slides make me sleepy too!
