W: If you want to get the car fixed in time, you'd better get a mechanic to do the job than do it all by yourself.
M: You have a point. But you know it'll be beyond my budget.
Q: What is the man doing?
正確答案：C

M: It's partly your own fault. You should never let in anyone like that unless you're expecting him.
W: It's all very well to say that, but someone comes to the door and says"electricity" or "gas" and you automatically think he is OK, especially if he shows you a card.
Q: How does the woman feel about the man's remarks?
正確答案：A
解析：男士責備女士不該讓陌生人進來，女士說“說起來容易，但是……”，言外之意就是做起來難。所以A正確。She選項題，女士的話是聽音重點。
