听力原文:M: Hey! How was your trip? W: Wonderful! I spent most of my time at the art museum. I especially like the new wing. I was amazed to hear the guide explain the problems they had in building it. M: Right. I just read an article that went on and on about the cost. 90 million total I think. W: Yeah. The guide mentioned that. You could see they spared no expense. M: Hm. It looked really unusal, 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 mobile. It's in the courtyard and it's made of pieces of aluminum that moves slowly in the air. It's really impressive. M: That was in the article too. It said that the original was steel and it weighted so much that it wasn't safe to hand. 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 borrow the magazine sometime? M: No. I wouldn't mind of I haven't thrown it ont yet. (20)
