pool在第二个话轮中女士描述自己的活动时，第六句即指出；And then I sometimes...in my pool。注意本题也可由常识得出答案，因为游泳(swim)只能在她自己的游泳池中进行。

M: So, Lily, now that we’ve heard that you work outside. Tell us about what you do on weekends: when you get up, what you have for breakfast, what you do for fun, and things like that.
W: Well, I get up very early, around five o’clock, because...
M: Five o’clock! Even on weekends? Do you do that often?
W: Oh, yes, nearly every weekend. I never sleep late There is just too much to do. I hate waking up late. Even on weekends. And then I sometimes go for a long swim in my pool, when I don’t go for a run. Exercise is very important to me.
M: At five o’clock in the morning you go for a run?
W: Yes, sometimes, or as I said, sometimes go for a swim.
M: OK... and then?
W: Well, then I have breakfast, and after breakfast I get down to work.
M: Oh, you work on weekends, too?
W: Oh, yes, I always work on weekends.
M: But don’t you ever relax?
W: Relax?
M: You know, take the day off and have a good time, enjoy yourself? Go to a museum or to the park or something.
W: Oh, no. I never go to the museum. But I enjoy myself. I always enjoy myself at work.
M: Well, OK. Thank you, Lily Tarkis. Bye-bye.
