听力原文:M: Hello, 24th Precinct. Officer Jones speaking.W: Help. Yeah, uh, it was wild, I mean really unusual.M: Calm down! Now, what do you want to report?W: Well, I'd like to report a UFO sighting.M: A what?W: What do you mean 'what'? An unidentified flying object!M: Wait, tell me exactly what you saw.W: Well, I was driving home from a party about three hours ago, so it was about 2:00 a.m., when I saw this bright light overhead.M: Okay. And then what happened?W: Oh, man. Well, it was out of this world. I stopped to watch the light when it disappeared behind a hill about a kilometer ahead of me.M: Alright. Then what?W: Well, I got back in my car and started driving toward where the UFO landed.M: Now, how do you know it was a UFO? Perhaps you only saw the lights of an airplane, or the headlights of an approaching car. Things like that happen, you know.W: Well, if it was that, how do you explain 'the BEAST'?M: What do you mean 'the BEAST'?W: Okay. I kept driving for about five minutes when all of a sudden, this giant, hairy creature jumped out in front of my car.M: Oh, yeah. Then what?W: Well, then, the beast picked up the front of my car and said, 'Get out of the car. I'm taking you to my master!' Something like that.M: Wow? A hairy creature who can speak English! Come on!W: I'm not making this up. Then, when I didn't get out of the car, the beast opened the car door, carried me on his shoulder to this round-shaped flying saucer, and well, that's when I woke up along the roadside. The beast must have knocked me out and left me there.M: Well, that's the best story I've heard all night. Now, have you been taking any medicine, drugs, or alcohol in the last 24 hours? You mentioned you went to a party.W: What? Well, I did have a few beers, but I'm telling the truth.M: Okay, okay. We have a great doctor who deals with THESE kinds of cases.W: I'm not crazy.M: Well, we'll look into your story.
