M: Mark was looking for you this morning. He wanted to know if you had decided when to go to the museum. And he seemed quite eager to meet you.
W: My goodness, I don't know how many times he's talked about it. When did he become such a nagger?
Q: What does the woman mean?
正确答案：C
解析：关键是听懂女士说的“不知他讲了多少次，他什么时候成了这么一个nagger”，nagger意为“喋喋不休、没完没了地说话的人，婆婆妈妈的人”。故选C。nagger是由动词nag派生而来，nag意为“唠唠叨叨”。

M: I guess we'll have a hot summer again.
W: I know. Last summer was mild. Do you remember our first summer here? The temperature stayed about 100 degrees Fahrenheit for ten straight days. There wasn't a breeze anywhere.
Q: What does the woman say about their first summer?
正确答案：C
解析：
事实细节题。预读选项可知，问题问的是过去某时的天气状况。听音关键是要分清楚他们对每年夏天的不同描述。根据女士对第一个夏天的描述“华氏100度”，以及“没有一丝风”，可知非常炎热。故选C。
