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

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

M: Okay, I think I've got enough coins for the machines. You're a lifesaver, Marylyn!

W: No problem. But I don't understand why you need my notes, Matt; 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 Marylyn, am I beat？

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. I'm so happy that you lend your notes to me.

W: Well, here's Professor Labelle; how are you feeling？

M: I'm usually awake at the beginning of class. But after thirty minutes, I have trouble keeping my eyes open. That's re ally terrible, isn't it？

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

M: Yeah, that's a good idea. I'd sure appreciate it.

W: Okay, 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!
