Topic: At the Dentist 去看牙医
Mary: Hi Sam. What’s the matter? Are you in pain?
Sam: Yes. I have a horrible toothache. I can hardly think straight.
Mary: What is wrong? Do you have a cavity(n.洞,蛀洞)?
Sam: Yes. The last time I was at the dentist, he told me that Ineeded to get a filling. He warned methat if I ignored the problem, it would only get worse.
Mary: I take it that you chose to ignore your dentist’s warning. Whywere you so foolish? You could have avoided all the pain.
Sam: To be honest, I was afraid. I once had a terrible experience atthe dentist. I had to have a tooth extracted(v.拔，萃取) and it was sosore (adj.疼痛的). It hurt terribly.
Mary: Didn’t the dentist give you any medicine to stop the pain?
Sam: He gave me a little anesthetic(n.麻醉剂), but perhaps itwasn’t enough. Also, the anesthetic injection was a nightmare. I saw theneedle that the dentist used and it was huge.
Mary: I completely understand your problem, Sam. Unfortunately, youwill probably need root canal now. This is a very expensive, long andexcruciating(adj.折磨人的) operation. Getting a filling will feel like a picnic(n.[俚]轻松愉快的事情) incomparison to this.
Sam: I always feel better after speaking to you, Mary.
can’t think straight: to be unable to consider things carefully orcorrectly 不能仔细正确地考虑事情
