Conversation Two
W: Hi, Dr. Hyde.
M: So, what seems to be the problem today?
W: Well, I just came in for a [23]check up and a dental cleaning.
M: Hum. Open up. Let's take a look.
W: Ok. Uh...
M: Well, there is a major [24]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 hurts when I try some grapefruit or an ice-cream. Is it really bad?
M: Well, we're going to [25]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, [25]I recommend a high-strength silver alloy filling instead of a porcelain one. It'll probably last longer.
W: [25]OK, well, whatever. Let's get it over with.
M: Okay, pleasant dreams. Drill please.

Questions 23 to 25 are based on the conversation you have just heard.
23. What is the woman's initial reason for visiting the dentist?
正確答案：C
解析：女士說(shuō)她來(lái)是為了做牙齒檢查和洗牙。故答案是C。從選項(xiàng)可猜測(cè)問(wèn)題與女士的牙齒檢查有關(guān)。行為或行動(dòng)的目的，通常會(huì)在對(duì)話的一開(kāi)頭就提出，所以要注意開(kāi)始部分。
24. What problem does the dentist discover?
正確答案：D
解析：男士說(shuō)，在女士其中一個(gè)智齒上發(fā)現(xiàn)有個(gè)洞，故答案為D。由選項(xiàng)可猜測(cè)問(wèn)題與牙齒毛病有關(guān)。注意wisdom tooth是最后長(zhǎng)出來(lái)的一顆back tooth。就算不懂兩者之間的關(guān)系，聽(tīng)到decay就知道答案。
25. What is the treatment the woman probably receive?
正確答案：A
解析：男士說(shuō)，對(duì)蛀牙的治療可先清除爛掉的部分，然后用填充物把它補(bǔ)上，并建議填充物選銀合金比瓷的要好，病人并沒(méi)有異議。故答案是A。每個(gè)選項(xiàng)都含有兩到三個(gè)信息，需迅速簡(jiǎn)化，抓住重點(diǎn)。對(duì)話結(jié)尾三次提到filling一詞，憑此即可確定A選項(xiàng)。
