M: You know the weather's been awful so far this summer.
W: I know. This is very unusual for Japan. Usually by now, it's really hot and humid. I'm not sure why, but this summer we've had very little rain and surprisingly cool temperatures.
M: Well, either way I love it. I remember last summer. Oh, it was terrible. I didn't have an air-conditioner, and my apartment was on the fifth floor. Every night I slept on top of my bed with the windows wide-open and a fan six inches from my face.
W: That sounds pretty tough. I guess I've gotten used to the heat, so I don't notice it as much. However, last year was definitely a lot hotter than this year. And, to be honest, I am enjoying the break. What are summers like for you back home?
M: For one thing, there's little humidity. Seattle is right on the ocean so we always have a nice offshore breeze blowing in, and it doesn't really get hot until late July. That's why I found it so oppressive last year. Our summers are just so different.
W: Interesting. Seattle sounds like a great place to be during the summer.

答案解析：

(2) 正确答案为C。根据to be honest, I am enjoying the break. 说实施，我很享受假期。可知，女子很享受暑假，因此C项正确。
(3) 正确答案为C。根据there's little humidity.西雅图并不潮湿，可知，有关西雅图不正确的是C项，西雅图的夏天非常潮湿。另外两项男子均有提到，Seattle is right on the ocean西雅图就在海边，可知A项，西雅图是海岸城市，是正确的描述；it doesn't really get hot until late July.西雅图要到7月底才会热起来，可知B项也是正确的描述。因此不正确的描述就是C选项。
