听力原文:Man: We always start our vacation the first week of August, and we spend the whole month out of town. We've been doing this for years. Woman: You're lucky you can take such a nice long vacation. Two or three weeks really isn't enough, is it? Man: No, it isn't. We're renting a house by the lake this time. I'm really looking forward to swimming everyday. Woman: Well, to each his own, I guess. I like to spend my vacations traveling to different cities. I like to be in a different place each day. Man: I find it more relaxing to stay in just one place. I remember when I was young, we always spent vacations at the lake. That's why I like to go there now. How long is the man's vacation?
