A、about 12:00 AM B、about 3:00 AM C、about 5:00 AM D、about 24:00 C计算题。报案人说他三小时前即凌晨两点钟看到UFO，所以他报案时间应该是凌晨5点钟。其他三个时间都不正确。故选C。

Police Officer: Hello. 24th Precinct. Officer Jones speaking.
Man: Help. Yeah，uh，it was wild，I mean really bizarre.
Police Officer: Calm down sir!Now，what do you want to report?
Man: Well，I’d like to report a UFO sighting.
Police Officer: A what?
Man；What do you mean“what”?An unidentified flying object!
Police Officer: Wait，tell me exactly what you saw.
Man: Well，I was driving home from a party about three hours ago，so it was about 2:00 AM，when I saw this bright light overhead.
Police Officer: Okay. And then what happened?
Man: 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.
Police Officer: Alright. Then what?
Man: Well，I got back in my car and I started driving toward where the UFO landed.
Police Officer: 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.
Man: Well if it was that，how do you explain“the BEAST”?
Police Officer: What do you mean，“the BEAST”?
Man: Okay. I kept driving for about five minutes when all of a sudden，this giant，hairy creature jumped out in front of my car.
Police Officer: Oh，yeah. Then what?
Man: 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.
Police Officer: Wow?A hairy alien who can speak English!Come on!
Man: I’m not making this up，if that’s what you’re suggesting. Then，when I didn’t get out of the car，the beast opened the car door,carried me on his shoulders to this round-shaped flying saucer，and well，that’s when I woke up along side the road. The beast must have knocked me out and left me there.
Police Officer: Well，that’s the best story I’ve heard all night，sir. Now，have you been taking any medication，drugs，or alcohol in the last 24 hours?You mentioned you went to a party.
Man: What?Well，I did have a few beers，but I’m telling the truth.
Police Officer: Okay，okay. We have a great therapist that deals with THESE kinds of cases.
Man: I’m not crazy.
Police Officer: Well，we’ll look into your story. Thank you.
