W: Let me see. Here are two pairs of slacks, one lady's skirt, and one man's overcoat.
M: And this sport shirt, too. All cleaned and pressed. When will they be ready?
Q: How many pieces of clothes did the man want washed?
正确答案：C

M: How did you like yesterday's play?
W: Generally speaking, it was quite good. The part of secretary was played wonderfully, but I think the man who played the boss was too dramatic to be realistic.
Q: How does the woman feel about the man's acting in the play?
正确答案：D
解析：关键在于对“too...to”的理解。它是一个暗含否定意义的词组，too dramatic to be realistic表示“太戏剧化了以至不够真实”，D项（他夸大了他的角色）与之意思相符，故选D。女士一开始说表演总的来说不错，“但是”表转折，提出不足之处。本题符合短对话听力“听到什么不选什么”的原则。干扰项听到的与原文对应的部分分别是：A--played...well，B--dramatic，C--secretary。
