A、Business. B、Computing. C、Architecture. D、He hasn’t decided yet. D对话中，女士询问男士的专业，男士回答说他一直考虑进入商界，但他还没有做出决定，故本题答案为D 。

W: So, what’s your major?
M: Well, (19) I’ve been thinking of going into business, but I haven’t decided yet. And my dad keeps telling me that computing is a good choice, but I’m undeclared at the moment.
W: Ah, that’s what happened to me my freshman year. But I would suggest you stick to your dreams, because you will have fun in it, just like me. By the way, I major in architecture.
M: Oh, so what year are you in school?
W: I’m a senior, and I only have to take 10 more credits to graduate. Yeah!
M: Well. That must feel great to be almost finished with school.
W: You can say that again, but once I graduate, I have to start repaying a student loan, so I’m not looking forward to that.
M: But didn’t your parents help you out with your college tuition?
W: No. My dad said he wasn’t made of money, so he thought I should earn my own education.
M: Really? But isn’t that so cruel? I didn’t mean to offend you; I mean, it must be so hard.
W: Well, actually, I was so angry with him at first that I avoided talking to him. And after a few months, I came to understand him. (21) You know, he is the only man that has a job in our family, and a teacher’s salary is just not enough.
M: Then how did you manage it?
W: (20)I did several part-time jobs and worked like crazy during holidays to cover most of my costs. And, I received some financial aid and a scholarship one, ear, which really saved me.
M: Well, have you lined up a job yet?
W: Not yet, but I’m trying to line up a few interviews at the job fair next month.
M: That’s cool. Good luck!
