What are they talking about?
【正确答案】
B
【答案解析】[听力原文]
W: Look, it says they want a junior sales manager and it seems like it's a big company. That'll be good, for you might have to travel a lot.
M: Do they say anything about the experience?
W: Let me see. It says the candidate should have at least two years' experience as salesman.
M: So there's little hope for me to get the job.
这是要求根据对话内容判断对话主题．听清关键词want a junior sales manager、company及 experience就可知谈论的是一个工作机会。

M: Charles enjoyed his two-week drive through South China.
W: Yes, he said that he saw much more than he would have travelling by bus or train.
本题的关键词是his two-week drive，而女士回答中的虚拟句he saw much more than he would have travelling by bus or train显然是说他没有乘公共汽车或火车。

What will the woman probably do?
【正确答案】
C
【答案解析】[听力原文]
M: It's such a beautiful day. Why not sit out in the backyard for a while and enjoy it?
W: I'd love to. But there's a lot of laundry to do.
对话中男士提出建议，而女士回答说，她很愿意，接下来用连词but(但是)把话锋一转，表明自己还有许多衣服要洗(婉转拒绝)。她既然拒绝对方建议，说自己有衣服要洗，显然是要洗衣服了。注意 laundry就是[C] 中的wash clothes。

D
【答案解析】[听力原文]
M: Prof. Kennedy has been very busy this semester. As far as I know, he works until midnight everyday.
W: I wouldn't have troubled him so much if I had known he was so busy.
女士的回答用的是虚拟句：要是我知道他这么忙就不会老去麻烦他了。由此可推断女士在不知情的情况下已经麻烦过教授，因此感到后悔。
