【答案解析】[听力原文]
   M: Hi, Janet, where were you at lunch time? I was saving a seat for you in the cafeteria.
   W: Oh, sorry to miss you. But my thirst for knowledge was greater than my pains of hunger.
   M: I never had that problem. So where were you?
   W: My political science class ran overtime.
   M: That's been happening quite a bit lately, hasn't it?
   W: I guess so. Actually, what happens is that a bunch of us hang around for a while after class to talk with our professor and ask him questions.
   M: Who is this twenty-first century Socrates?
   W: Professor Howl.
   M: No wonder.
   W: Have you ever heard of him?
   M: Mh, he does have a good reputation in the political science department and I heard many people speak highly of him.
   W: And a well deserved one. The same students who fall asleep in discussion groups and seminars fight for front-row seats in his lectures.
   M: Oh, no. I hope this isn't catching.
   W: You can joke. But it's great to have a professor who's not only interesting but prepared to give up time for students.
   M: I know. They are a rare breed. Maybe I should sit in on his class sometime. Do you think he'd care?
   W: Not at all. Lots of students bring their friends, and he says he feels flattered.
   M: Well, just to be on the safe side. I think I'll bring my lunch along as well.
   W: I'll make a good student of you.
   Why did the woman fail to have lunch with the man?
①从选项可知问题问的是女士的行为。②对话中听到男士提问where were you...?时,要特别注意女士的回答——“我们的政治课超时了。”C是对该处信息的同义表达,prolonged对应录音中的ran overtime,故C为正确答案。
   全篇对话内容与“政治课教授上课受学生欢迎”有关,可知女士不在餐厅用餐肯定与政治课有关。A“她忘记时间了”和D“她偶遇一个老朋友”未提及。B“她不觉得饿”,录音中女士在为自己失约致歉的时候说到,她对知识的渴求更甚于腹中之饥,由此可知,她并不是不饿,故排除B。
