【答案解析】[听力原文] 8-10
M: Good morning, Madam. What can I do for you?
W: Good morning. How much should I pay for these books to be sent to New York?
M: Hm, 20 dollars. Anything else?
W: Yes, a two-dollar stamp, please.
M: That will be 22 dollars all together.
W: Here's 25.
M: Thank you. And here's the change.
W: Thank you.
M: You're welcome.
本题为地点题。由男士的What can I do for you这一常用语及女士回答中的pay for these books to be sent to New York即可推知，对话发生在邮局，男士是邮局工作人员而女士是顾客，选[A]。

【正确答案】 A

【答案解析】[解析] 在第二轮对话中女士用省略句说：a two-dollar stamp，即她只买一枚邮票，故答案是[A]。

【正确答案】 C

【答案解析】[解析] 本题为数字题，需要在听清对话的基础上进行简单运算。在第三轮对话中，男士指出女士的费用共计为22美元，女士则说给他25美元，因此找的钱当然就是3美元了，答案是[C]。
