【答案解析】[听力原文]
W: I just got off the phone with Dale, from the hiking club. Our trip to Pacific Mountain National Park was canceled.
M: Ah, that"s such a shame. I was really looking forward to it. Did he say why?
W: He did. There was an avalanche this morning on the trail leading to the summit. The park rangers are not allowing anyone to enter the park at all.
M: I see. It should only take a few days to clear the path. I hope he can reschedule the trip soon.
W: He mentioned that. He thinks he can arrange for us to hike through the national park sometime early next month.
选项A错误，“a park ranger”是在国家公园工作的人。选项B正确，地名告诉我们他们要去国家公园。选项C可能混淆了“Pacific Ocean”和虚构的名字“Pacific Mountain”。选项D混淆了“a summit”(峰会)和“summit”(山的最高处)。
