听力原文：W: Good morning. This is Mrs. Jackson. May I please speak with Dr. Ellis? M: Dr. Ellis is speaking, Mrs. Jackson. How's that new bridge? W: Not so good, doctor. That's what I'm calling about. It just doesn't seem to fit right. M: Well, that's to be expected during the first few days after it has been put in. As I told you, there will be no complications. W: It hurts so much, especially when I eat. I keep removing it afterwards, you know. M: I understand, Mrs. Jackson. It does hurt in the beginning, I know. But it would be better if you didn't remove it, except when cleaning it, of course. W: Well, I did at first, doctor, but my gums hurt so much that I just can't stand it any longer. M: Well, maybe we can adjust it a little more. W: Adjust it? M: Yes, file it down a little here and there. When can you come in? W: Oh, right away, doctor, if you don't mind. M: Let me see, I'll check here now. Maybe I can find the time for you this morning. W: Oh, I can wait until this afternoon if you you're too busy now. M: Sorry, Mrs. Jackson, but I'd rather you'd come this morning if possible. This afternoon I'm teaching a class at the dental school. Just a minute. Mrs. Jackson, can you get here about 11:30? That will give us enough time before lunch. We'll see what we can do. W: Oh, yes doctor, I can make it. Thank you. See you then. (23)
