【正确答案】 C

【答案解析】[听力原文]6-7
W: Good morning, Burwood Hospital. Can I help you?
M: Yes, can I make a doctor's appointment sometimes tomorrow?
W: Yes. With Dr Smith?
M: Yes, I want to have an appointment with Dr Smith.
W: What time is good for you tomorrow?
M: What about 4:30 tomorrow afternoon? I will come after work.
W: Four thirty? I am sorry; he will have another appointment at that time. Could we make it for five, please?
M: Five o'clock would be fine.
W: What is your name?
M: Martin Frank.
W: OK, see you tomorrow, Mr Frank.

在第四轮对话中，女士在反问男士提出的时间(Four thirty?)之后，对此进行了否定并解释了原因：I am sorry；he will have another appointment at that time，即Smith医生在4:30时另有预约，故选[C]。

【正确答案】 C

【答案解析】在第四轮对话中女士问男士5点钟如何，然后男士回答说：Five o'clock would be fine，即同意了这一时间，因此答案是[C]。
