M: I'm still waiting for the clerk to come back and make some copies of this paper for me.
W: Why trouble him? I'll show you how easy it is to work with the machine.
对话中男士说自己还在等服务员回来给自己复印论文，而女士先用省略句反问(why trouble him的意思就是不用麻烦他即服务员)，然后说：I'll show you... (我做给你看…)，其意显然就是要帮助男士，故答案是[A]。

M: Good morning, City Taxi.
W: Good morning. I'd like to book a taxi to the airport for Saturday morning, please.
M: Where from?
W: I'm at Garden Hotel in Union Street. There will be three of us sharing. How much will it be?
M: About 60 dollars.
W: 60 dollars? Each of between us?
M: Oh, that's all together. What time do you want to leave?
W: Seven in the morning.
M: Right! We'll pick you up at your hotel at seven then.
W: Thank you very much. Goodbye.
本题要求根据对话内容推断对话主旨。在第一个话轮中，男士首先报出了自己的单位是City Taxi(城市出租车公司)，女士则明确提出了自己的目的是book a taxi(预订一辆出租车)，后面的话轮中双方谈论了价钱、时间以及地点等细节内容，故对话主旨就是租用出租车(hiring a taxi)，选[C]。

【正确答案】 A

M: Mum, I am so excited that I don't want to go to bed.
W: John, I know you will go out on a picnic with your classmates. But you should try to fall asleep; otherwise you will not get up on time tomorrow morning.
本题询问的是对话中的细节。从女士第一句话中的I know you will go out on a picnic即可得出答案，选[A]。注意，go picnicking相当于go on a picnic。

M: Hello, this is Room 205. What time is the dinner, please?
W: The main restaurant opens at 7 in the evening and closes at 10. Our coffee shop is open 24 hours a day.
M: And what time is it now, please?
W: It's 6 p.m., sir.
M: Thank you.
本题是地点题。关键词是男士问句中的Room 205及女士回答中的Our coffee shop is open 24 hours a day，再据常识即可推知，对话发生在旅馆里，男士是房客，女士是前台服务员。

【正确答案】 C

【答案解析】[听力原文]
M: Is it true that you don't do gymnastics at all now?
W: I'm afraid so. I'm too old.
M: But you are only twenty-two!
W: That's too old for a gymnast. If I played in an international championship now, I couldn't win. So I'd rather not do it at all.
本题的关键是听清女士的最后两句话：If I played in... So I'd rather not do it at all，即她是因为自己年龄太大、不能再在国际性比赛中获胜才决定不再搞体操了，选[C]。
