A、She had promised that she would. B、She has been sick. C、She needs his approval for her schedule. D、She must verify his plans.

W: Excuse me, Dr Tyler, your secretary said I should come right in.
M: Please do. Jenny, how can I help you?
W: I need to get your signature on my schedule card here, on the line above advisor’s approval.
M: Sure, but let’s look it over together first. How many courses do you have here?
W: Six.
M: Six? That’s quite a heavy load. Any particular reason?
W: I had to drop my chemistry course last semester when I was in the hospital, so I need to take it again.
M: So you’ve already learnt a lot of the material.      
W: Right. And calculus is a part of the second year requirement.
M: Let’s see, chemistry, calculus. Oh, I See you’ll be in my seminar on the modern American novel.
W: Yes, I’m looking forward to it and to the romantic poetry seminar, too.
M: Two seminars? That is rather a lot. Can you handle the work?
W: I think so. The introductory economics class is very easy and so is the music course.
M: Well, then I’ll be happy to sign the card. However, I must insist that you come see me after the first week of classes so that we can make sure this isn’t too much for you.
W: That’s a promise.
