听力原文：W: Oh, Jack, I'm glad I called you. I want to tell you I have to skip the history

M: Really？ That's too bad. Are you feeling well？

W: Oh, it's not bad. It's going to be a public meeting down the town hall. The state senator from this area is going to be there. She has this meeting three or four times a year to speak with her constituency.

M: Is that you'd like to do with your evening, going to listen to a politician's...

W: Actually, it's a class assignment. Prof. Jackson, he's teaching that political science seminar I'm taking. He told all of us in the seminar to hear what the senator has to say tonight and also write up a report about the issues people bring up.

M: Oh, like medical care, and tax and... ？

W: Right, as long as I'm there, I think I'd like to bring up government funding for state universities. The tuition keeps going on and it's getting harder and harder for a lot of students to afford it.

M: Tell me about it.

W: Anyway, I want to do a really good job on this report. I need to get a letter of recommendation from Prof. Jackson for grad school. So I guess I'd better show up there tonight and see what's going on.

M: Yeah, but, what about the history test？

W: Well, I already put some time on that this morning. So I think by tomorrow afternoon, I'll be eady.
