听力原文：M: You'll be in Room 207. Here's your key, and I hope you enjoy your stay with us

W: Thanks. Oh, by the way, rd like to get some information from you. You see, the conference I'm attending will be over early Wednesday, and I don't fly out until Thursday. Do you have any recommendations for sight seeing？

M: There's a great planetarium at Our natural history museum. You might enjoy that.

W: I don't know--I don't think I want to do that. The city I come from has a good planetarium.

M: There are also some good art galleries downtown.

W: I'm more interested in doing something outdoors. M: Oh, well, there's a beautiful waterfall called Crystal Falls not far from here.

W: That sounds like something I'd enjoy seeing. How do I get there？

M: Do you have a car, or will you be taking a bus？

W: I rented a car at the airport.

M: Then just take Waterson Street west out of town and go about five miles. You'll see a sign that says Crystal Falls. It's a short walk from there.'

W: That sounds great. Thanks !
