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. Why did the woman talk to the professor?
