听力原文：M: Did you see that (23)TV special on Norman Rockwell last night? W: Yes, I did. It was really good, wasn't it? M: It sure was. I thought it was really interesting how he (25)developed the paintings in states starting with photographs. W: Yes, I did, too. It never occurred to me that he would have actually employed models. I just assumed that he invented all those wonderful characters. M: I know. (24)But it does make sense to use photographs of real people， to solve as many of the composition problems as possible before starting to paint. w: True. Anyway, you know what I like most about his work? M: What? W: Well, when you look at one of the magazine covers, which magazine was it? M: The Saturday Evening Post. W: Yes, you can just tell what the people are thinking and feeling. The picture really tells a story. M: You're right. I like that, too. And to think that he created several hundred of those. W: Amazing. Of course, that was over a period of almost sixty years, but still… M: I'd like to see them when that exhibit comes to Miami. W: What exhibit? M: The one they mentioned after the special. W: Oh. I must have turned it off before the announcement. I'd like to see it. too. Let's go. (20)
