Conversation Two
M: How do you like the new art museum?
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 the problems they had building it.
M: Right. [23]I just read an article that went on and on about the cost. 90 million in total I think.
W: Yeah. The guide mentioned that. You could see they spared no expense.
M: Hm. It looked really unusual, at least from what I saw in the picture.
W: It is. [24]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 moves slowly in the air. It's really impressive.
M: That was in the article too. [25]It said that the original was steel and it weighed 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 if I haven't thrown it out yet.

答案解析：
Questions 23 to 25 are based on the conversation you have just heard.
23. How had the man learned about the museum?
[C]解析：对话中男士说：“我刚读过一篇文章，详细介绍了它的建造费用。”因此只有C最合适。主语都是He，本题应重点关注男士说的话，听到对话中男士说的“I just read an article...”，“听到什么选什么”，动词的原词再现清楚地标示了答案。
24. According to the woman, what do the paving stones, skylights and mobile have in common?
[D]解析：对话中女士说：“其基本设计是两个三角形。事实上，那里到处都是三角形：院子里的铺路石啦、天窗啦，甚至许多雕塑作品都是三角形的。”D正确。本题答题之处语义特征明显，题目本身也指代清楚，所以并不难解答。
25. What was the problem with the original mobile?
[B]解析：男士说：“文章也介绍了那个移动雕塑。它说，该雕塑原本是用钢铁做的，实在太重了，把它挂起来不安全。”句中hand作及物动词，表示“支持、搀扶”，这里指让雕塑在空中悬挂住（而不致摔落），并能在空中移动。因此，B正确。
