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?
正确答案：C
解析：女士建议男士找机修工来修车，男士说“你说得有道理”，但他接着说“但这将会超出我的预算”。因此C正确。根据选项可预测题目是问男士正在做什么。but转折题。but后的内容是听音重点：男士还是决定自己修车。

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?
正确答案：A
解析：男士责备女士不该让陌生人进来，女士说“说起来容易，但是……”，言外之意就是做起来难。所以A正确。She选项题，女士的话是听音重点。
