　　CE: Teens 在2009年7月号的“口语角”中选录了关于“世界末日”这个主题的迷你剧《月殒天劫》,感兴趣的同学可以再次回味哦! 　　　　Host: French researchers are predicting doom for Planet Earth.
　　Hostess: They believe neighboring planets could stray[偏离] out of orbit and collide[相撞] with the Earth billions of years from now. David Shukman explains their theory.
　　A view of Earth from orbit and a strange question: how long would it last? Scientists have long known about the violent events that formed solar system. But now they’ve studied the movements of our nearest neighbors.Mars, they reckon[测算], could drift uncomfortably close or do this �  if we’re really unlucky, it could actually collide with us. Literally, the end of the world.
　　So what exactly is this research saying? Well, one key thing that the orbits of the planets which look steady aren’t all that regular. Over the years, some start to move pretty wildly. These are the projected tracks. And the odds[可能性] are that will lead to a very big collision in about 3 billion years’ time.
　　With that long to go, the researcher involved doesn’t look too worried. But amid the old instruments of the observatory in Paris where he works, he has a doom-laden[装满的] message about the future and what a collision would eventually mean.
　　Expert: It would be totally devastating[毁灭性的] because the relative speed is very high. They go at ten kilometers per second. So it’s ten times the velocity[速度] of a bullet. And the impact is enormous. Everything will be destroyed on Earth.
　　Until now, the worry has been one of these, an asteroid[小行星]. It’s thought one of them finished off the dinosaurs. Think what a planet would do. But this is just a computer graphic. The calculations may be wrong. The only people who need to react to this research are film producers in Hollywood.
　　
　　男主播:法国研究人员正在预测地球的大限之日。
　　女主播:他们认为,几十亿年后,邻近的行星可能会偏离其运行轨道和地球相撞。大卫・舒克曼为您解释他们的理论。
　　从轨道上鸟瞰地球,人们不由想起有一个奇怪的问题:它还会在宇宙中存在多久?科学家很早以前就知道太阳系形成时发生了剧烈的造星运动。现在他们已经研究离我们最近的“行星邻居”的运动状态。他们认为,火星会漂移并非常靠近地球,或者做出这样的事情――如果我们真的这么倒霉的话,它可能与地球相撞。毫不夸张地说,那将会是地球的末日。
　　那么,这项研究到底揭示了什么?其中的关键一点是行星轨道看似稳定,实则不那么有规则。这些年里,一些行星的轨迹开始大幅移动。这些是我们预测的轨道,它们有可能在30亿年后引发一场非常严重的撞击。
　　既然还有那么长的时间,该课题的研究人员并不十分担忧。然而,埋身于巴黎天文台各种老式仪器中,他得出了一条关于未来的信息――这条信息充满危机感,它能解释这次撞击到底意味着什么。
　　专家:这将是毁灭性的一击,因为(火星的)相对速度非常高,大约是每秒10公里。这是子弹飞行速度的十倍。这场撞击将相当剧烈。地球上的一切都将被摧毁。
　　到目前为止,更让我们担忧的撞击物之一就是小行星。专家认为,正是一颗小行星(撞击地球)导致了恐龙的灭绝。想象一下一颗行星所能带来的后果吧。不过,这仅仅是电脑计算结果的模拟效果图。计算上也许会出错。现在唯一需要对这项研究成果作出反应的也就只有好莱坞电影制片人了。
