听力题 M: Hey, how was your trip? W: Wonderful. I spent most of my time at the art museum. I especially liked the new wing. I was amazed to hear the guide explain all the problems they had building it. M: Right. I just read an article that went on and on about the cost—ninety million total, I think. W: Yeah, the guide mentioned that. You could see they spared no expense. M: Hmm. It looked really unusual, at least from what I saw in the picture. W: It is. The basic design is two triangles. In fact, there are triangles all over — the paving stones in the courtyard, the skylights, and even a lot of the sculptures. One sculpture is a mobile, It''s in the courtyard and it''s made of pieces of aluminum that move slowly in the air. It''s really impressive. M: That was in the article too. It said the original was steel, and it weighed so much that it wasn''t safe to hang. W: Right. They did it over in aluminum so it wouldn''t come crashing down on someone''s head. M: You know, the article went into that in detail. There was even an interview with the sculptor. W: I''d like to read that. Would you mind if I borrowed the magazine sometime? M: No, I wouldn''t mind, if I haven''t thrown it out yet.
