【正确答案】
C
【答案解析】[听力原文] W: Hi, Dr. Hyde. M: So, what seems to be the problem today? W: Well, I just came in for a check up and a dental cleaning. M: Hum. Open up. Let's take a look. W: Ok. Uh. . . M: Well, there is a major cavity in one of your wisdom teeth. Hasn't this given you any trouble? W: Well, the tooth has been bothering me, and it sometimes huffs when I try some grapefruit or an ice-cream. Is it really bad? M: Well, we're going to remove the decay, and then we'll either put a filling in, or if the decay is extensive, we can't repair it, we might have to put a crown on your tooth. Or as a last resort, we may have to extract the tooth. W: Uh, well, that sounds painful! M: Don't worry. I've done this...once before. Nah, just relax. W: Wait! Aren't you supposed to give me something to dull the pain? M: Uh, chicken. Oh yeah. I almost forgot. We can either use a local anesthetic or laughing gas to minimize the discomfort you might feel. Or you can just grin and bear it. W: Nah, Nah, nah! I can't stand pain, and I'd rather not be aware of what's going on. And, if I need a filling, can I get one that looks like my other teeth? M: If we can save the tooth with a filling. I recommend a high-strength silver alloy filling instead of a porcelain one. It'll probably last longer. W: OK, well, whatever. Let's get it over with. M: Okay, pleasant dreams. Drill please. What is the woman's initial reason for visiting the dentist? 从选项可猜测问题与女士的牙齿检查有关。女士说她来是为了做牙齿检查和洗牙，故答案是C。行为或行动的目的，通常会在对话的一开头就提出，所以要注意开始部分。
