W: Jack, what a strange suit you are wearing! Your jacket doesn't match your pants.
M: I know. I got dressed in the dark, and I didn't realize my mistake until I had got to the office. And I can do nothing about it right now.
Q: What does the woman think of the way Jack's dressed?
正确答案：D
解析：细节题。关键是听懂女士的话“你的夹克衫和你的裤子不配”，所以答案选D。男士所说的in the dark是指自己“摸黑”穿衣服，而不是指衣服是黑色的，故B不对。

M: I'm going to the museum Sunday afternoon. There is a new exhibition of art from France and England. Do you want to go with me?
W: I'd like to. But my best friend is getting married in the Pacific Hotel and I wouldn't miss it for anything.
Q: What is the woman going to do this Sunday afternoon?
正确答案：B
解析：听到I'd like to... But...句型，立刻可以判断，这位女士不能接受邀请去博物馆，but后面说明原因“她的密友要结婚，无论如何她都不能不去”。故选B。
