听力原文：M: Come in, come in! Can I help you?
W: Professor Turner, are you giving your Advanced Geology course again next semester?
M: Yes.
W: I wonder if I could enroll in it, I know it's a graduate course and I' m only a junior, but. . .
M: Aren't you a bit young? I've allowed qualified seniors to take the course and they usually have a hard time to keep up.
W: I know, but the geology of the American West is my favorite interest and I've read a lot in the field. Last semester I took Professor Burman's course and I didn't find it challenging enough.
M: I see. You certainly aren't one of those students who are out for easy grades.
W: I should say not. I really want to learn something.
M: Well, I'll speak to Professor Burman, if he thinks you' re ready, I'll let you enroll.
W: Oh, thanks. Prof. Turner, that's very nice of you.
