W: Did you go see the doctor about your cough?
M: The doctor said if I keep smoking it will increase my chance of having a heart attack or lung disease. And I am thinking about quitting smoking as the problems seem to be quite serious.
Q: What do we know about the man?
解析：推断题。本题要在听懂原文的基础上推断出正确答案。女士问男士咳嗽去看过医生没有，男士转述医生的话，如果继续吸烟，那么他患心脏病或肺炎的几率将增大，由此可推断出男士的咳嗽是由吸烟引起的。关键词和短语是cough和keep smoking。男士的回答中a heart attack和lung disease是并列结构，所以A、B均不能入选。
W: Could you tell me how many of your employees are women?
M: Yes, certainly. We have a very high percentage of female staff. We employ about 160 women, which is eighty percent of all our staff.
Q: How many of the employees in this organization are men?
