听力原文:M: Hello, Janet. I'm glad to see you back. Did you have a nice holiday?
W: Yes, great! (20)We arrived at our hotel at five o'clock on Saturday afternoon and didn't really do anything much until the next morning when my father hired a small family car and we all went to Safari Park.
M: Safari Park? Where is it?
W: It is not far from London, full of lovely wild animals. (19)We motored through the monkeys' compound first and that was an experience. They climbed all over our car and we had a wonderful view of the monkeys.
M: Oh, it sounds interesting. It is the kind of park I like. Did you see any bigger animals?
W: Of course. We had to lock ourselves in when we were in the lions' compartment, because the lions could come very close.
M: Oh, it must have been terrifying. Did they come to you?
W: No. We saw them sleeping under trees, quite far away from us. We were unlucky and didn't see them clearly. Anyway, we had a good time there.
M: What else did you do?
W: On Monday we all went off to Oxford and spent a whole day there. On the way to Oxford we stopped at Stone henge (史前巨石柱).
M: Stonehenge! (22)It reminds me of my own experience when I was a student at Oxford. (21)I think it will be a rather romantic thing to drive off in the early hours of the morning and watch the sun rise behind the stones.
W: Right. It was a beautiful day when we got there. We took lots of photographs there.
M: You were lucky. You couldn't have seen the view if there bad been too much fog.
