【答案解析】[听力原文]
   M: Jane! Imagine seeing you here.
   W: Jack! Glad to see you too. I haven't seen you for ages.
   M: You know, I've been hoping to get hold of you. Would you be able to come over this Friday? My sister just returned from a trip to Canada. She'll be staying with Su for a few days. I thought you two might like to get to know each other since you two are both botanists.
   W: Oh! I'd love to. But I can't. I have to go up to my younger brother's graduation on Friday right after work. It takes about four hours to get to Seattle, you know.
   M: Seattle? I thought you were from Portland.
   W: No, I have just lived there for a few years.
   M: Well, it's really too bad you can't make it. When my sister was in Canada, she spent the whole time taking pictures of plants. I can't believe how good some of them are.
   W: Is there any chance that you could ask her to stay around for a little bit longer? I'll be getting back early Sunday.
   M: I doubt whether we can get her to stay much longer. She is busy.
   W: Well, if I can't get hold of her this time, maybe I'll have to wait till the next time she comes around.
