听力原文:W: Hi, Professor Johnson. M: Hi, Anna, What can I do for you? W: Remember 1 e-mailed you about getting the handouts from the class I missed the other day, and you said I could stop by and pick them up today? M: Oh, that's right. You know, that's the fourth class you've missed this semester. W: Sorry, but I had the flu. That'll be the last class I miss, though. I promise. M: How are you feeling now? W: Much better than a few days ago. M: That's good. Oh, the handouts. They're pretty self-explanatory, but if you have any questions, just send me an e-mail. W: Thank you. M: Uh, but we also watched a video, and we'll be having an essay question about it on the next exam, so, do you have a VCR at home? W: Yes. M: Okay ... Well I can lend it to you, but you'd have to watch it tonight and get it back to me early tomorrow, because I'm going to use it tomorrow afternoon. W: That'd be great. M: Okay ... How about if we do it this way. I'll keep it for now and show it in my class tomorrow, and then you can drop by here and pick it up on Friday morning and keep it for the whole weekend, and just bring it when you come to class next week. Then you'll have a couple of days to watch it, and you won't have to worry about getting it back here tomorrow. W: Great. I'll see you then. Why does the woman go to see her professor?
