【正确答案】 D

【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.
