听力原文：W: Hi Stan, where have you been？

M: Oh, just at the Student Union office trying to see if I can catch you there. I also tried to find out if professor Steinfield has any old exams from years ago.

W: Why don't you just ask me？ I took that class last semester and aced it.

M: Yeah... you ace all your subjects. But the exams change from year to year, don't they？

W: True, but the style. is pretty much the same from year to year.

M: So tell me all about the process of prostaglandin. I can barely even pronounce it, let alone explain it.

W: Hey, I am no expert but what she'll be mainly looking for is that you know how it affect the digestion, reproduction, and immune systems.

M: What kinds of questions might she ask？

W: Well, for example, you'll probably have to say how prostaglandin, if over-produced can give you headaches and fevers and stuff.

M: Talk about headaches. I think I'm getting one now. Can you give me an aspirin？

W: Well, it's probably because you have too much prostaglandin. Aspirin blocks prostaglandin production.

M: Well, I'm sure it's this Biology class that's doing it.

W: Hey, I've heard you're no slouch at poetry. You get me through my course in 19th century poetry and I'll make you an expert in Biology.

M: It's a deal. Where shall we begin？ Poetry is up my alley.
