Man: What subjects are you taking this semester? Woman: I’m taking Introductory Calculus, Freshman Composition, Western Civilization, and Physics.
Man: That’s quite a load.
Woman: Yes. I know it’s going to be a lot of work, but it should be an interesting semester. And I’m not going to have to work this term because I managed to save quite a bit of money from my summer job at the cannery. So I should have enough time to study.
Man: That’s good. I’m going to have to work twenty hours a week at the library.
Woman: What do you do there? Do you like it?
Man: I shelve books on the third floor. Sometimes it gets monotonous, but the pay isn’t bad. And I can arrange my hours to suit my class schedule.
Woman: What are you taking this semester?
Man: French, Biology, and Accounting. I like the French and Biology instructors, but the Accounting professor is very dry and boring.
Woman: Do you have Professor Stillwell? I’ve heard he’s terrible.
Man: Yes. Do you know of anybody who’s better?
Woman: My friend Antonio took Accounting with Professor Atkins last spring. He said that she was wonderful—knew her subject well and had a great sense of humor.
Man: I’ll have to check to see if she’s teaching this semester. If she is, I’ll try to transfer into her class.
