听力原文:M: How did you do on the exam?
W: I passed, but I didn' t do too well. The essay question was the worst part for me. How about you?
M: I did all fight on everything except the essay question, too. I wasn't really prepared to write about the election system in India. We studied the political system of India for only a few days. I didn't think it would be on the test.
W: Me either. I thought for sure he would ask us something about the arts customs in India or maybe the festivals in India. I studied most of the areas on India and didn't spend much time on the political system. Do you know how much the exam counts towards our final grade?
M: I think it's 30 percent.
W: Thirty percent! Oh no, I'm in deep trouble this time! That means I'll have to get A's on everything else to get a decent grade.
M: That may not be too hard. We' ve already gone through most of the readings the class is supposed to cover. After next week it will just be review. But then there is the final paper, of course.
W: Yes. I was hoping to do well on this test so I could relax when writing my paper, but now it looks like I'll have to spend more time preparing to write that paper.
M: Well, I will too. Hey, I' m kind of hungry. I think I'll go get .some lunch. Do you feel like joining me?
W: I'd love to, but I have to go home and study. I'll call you later.
M: OK, see you later.
