【正确答案】 C

【答案解析】[解析]
W: Mary said that she would go with us and told me to pick her up. But she didn't answer her door, and her phone's been off for an hour.
M: Well, if you don't get her soon, we'll just have to go to the party without her.
Q: Why is the woman trying to call Mary?

[解析] 推理判断。注意男士的表达：if... we'll 结构。后面假设的内容"we'll just have to go to the party without her." 揭示了他们打电话是为了带 Mary一起去参加派对。因此 C) 项符合题意。

【正确答案】 D

【答案解析】[解析]
M: You look so sleepy. Did you work on your term paper far into the night?
W: I would have got a good sleep but some soccer fans kept cheering and arguing.
Q: What happened to the woman last night?

[解析] 推理判断。 but 意为“要不是”。女士说昨晚上要不是那看花样滑冰的球迷又吵又闹，她就可以睡一夜好觉了。因此推知女士困倦不是因为熬夜写论文，而是被球迷吵得没睡好。因此 D) 项符合题意。

【正确答案】 C

【答案解析】[解析]
M: Which dress are you going to wear?
W: I like the black one which fits me better, but it's probably too dressy. I suppose I'll wear the red one.
Q: Why didn't the woman wear the black dress?

[解析] 语意理解。女士说不黑裙子，因为显得 too dressy 即“太隆重，过于讲究”，与 C) 项“因为对那个场合而言太正式”属于同义转述。因此 C) 项符合题意。
