新視野大學(xué)英語視聽說教程第四冊 Unit 6 MODEL3 I believe ETs have visited the earth before.
Nora: Hey, what’s this picture of yours? It looks like a flying saucer.
Chris: It is. I was visited by aliens last week and this is a picture of their spacecraft.
Nora: When I look closer, it resembles a liver Frisbee.
Chris: But it could have been aliens. I believe ETs have visited the earth before. What do you think?
Nora: It would be hard to believe otherwise. Projects like the pyramids are difficult to explain away, given the level of technology that was available at the time
Chris: That’s for sure. They are mysterious.
Nora: When you consider all those “impossibilities, it’s tempting to infer that some highly advanced civilization assisted humans in their construction.
Chris: Think about this: if you were abducted by aliens and taken up to their spaceship or something …well…
Nora: What do you mean?
Chris: I mean, who would believe you? You’d go nuts telling everyone: “It’s true! I was abducted by aliens!”
Nora: And everyone would think you were crazy, or just making up a story to get attention.
Chris: From what I understand, sometimes these people do go crazy, trying to convince people about their experiences.
Nora: I believe that in some cases they offer pretty good evidence.
Chris: So, take a closer look at this picture. Do you still think it’s a Frisbee?
