Conversation Two

听力原文

W: What’s going on with you lately? You seem so distracted, like you aren’t really listening to anything I say.

M: I know. I’m sorry. (12) I can’t seem to focus on anything, because I still haven’t decided if I should accept the offer for that PhD program in London, or if I should take the job offer in New York.

W: (12) Look, it’s a tough decision, but you’re running out of time, aren’t you? I thought you said the company expected an answer by the end of the month.

M: Actually, it’s the beginning of next month for the job, but the university needs a decision by the end of the week. So I have to act quickly.

W: You definitely need advice for an important decision like this. (13) So who have you talked to about it? What does your family think? And your advisor for your Master’s program?

M: (14) I’ve asked for their advice and that’s part of the problem. My parents want me to get the degree, but my advisor thinks it’s time for me to get more work experience.

W: What do you mean by “part of the problem”? Oh, wait, it’s your girlfriend, isn’t it? You’ve been dating since your first year of university, so that’s six years now. She must have an opinion about all this. I mean isn’t it time for you to think about getting married?

M: Well, I do want to get married, (15) but she thinks we need to wait until we’ve launched our careers. Plus, she’s not sure what she’ll be doing next year. She’s considering a job in England and one in Australia. And her parents are pushing for the latter.

15. Why doesn’t the man’s girlfriend agree to get married right now?

解析：B。录音最后提到，男士的女朋友认为他们应该等到两人事业都起步之后再考虑结婚。结合前面提到的男士在犹豫要不要接受工作邀请以及他女朋友在两份工作邀请之间犹豫可知，两人目前的工作还没有确定，故B项正确。其余选项均未在原文提到，故排除。
