听力原文:Maggie Hey, Jim, what a coincidence to see you here! Long time no see! Jim Yeah, me too. Hey, just as old friends, I gotta tell you...you dont look that well. Are you sick or something? Maggie Well, not really. Seems really serious? Jim Um, not that bad. But...whats wrong? Maggie Guess what? Its the same old story of an overworked undergraduate student. I am up to my neck on one project. Jim How did you end up like this? Is the timeframe. limited or its near the deadline? Maggie Actually I am working on a project that has to be done by the end of this month. Jim Oh, thats it. Cant you speak to your professor about that? Maggie About what? The project or something else? Jim Of course the project. Maybe he would allow an extension and you will then have some breathing space. Maggie Fat chance. Youve never met him, right? Jim Exactly. What is he like? Maggie You know, my professor is one of those workaholic types and he expects everyone that works with him has to be the same way. You know, sometimes he sleeps four hours a night but can still keep going during the day. Jim Wow, sounds like your professor is really nuts. I dont mind working hard, but not to the point of killing myself. Hope you can get your project done without any hitches. Maggie What about you? I heard the faculty building is being constructed on campus. A big project it seems by the looks of things, and its nearly completed, I think. Jim Well, not quite there yet. They still have not decided whether they should move there or not. Maggie Whats the Department Deans opinion? Jim He wants me to mark papers and do some administration work for them. I have to make a decision by the end of this week. Maggie That is a tough decision, isnt it? I would jump on the offer if I had one. To work with some of these academic types must be interesting. Jim Sure it is. I would not think twice if I didnt have such a heavy load this semester. Besides, my girlfriend isnt keen on me always spending time at school. Maggie I can understand how she feels. Maybe you can ask for a light load. Perhaps you should request to work only on certain days. Jim Thats true. Then I wouldnt have to work under a workaholic professor any more. Maggie Hey, Jim. Do you think I have any chance of getting some work there? Jim Hmm...are you serious about working there? I thought you were joking.Narrator Listen to part of a conversation between two students.
