太空并非一片净土,每天都会有成千上万的太空垃圾有可能造访我们的星球。它们会给我们的地球带来毁灭性打击吗?今天的新托福考试阅读练习资料我们就来讨论这个话题。

In his book Cosmos, the late scientist Carl Sagan talks about the way in which the earth is regularly struck by material from outer space. These collisions with space debris can be minor–as in a shooting star on a summer night–or amazingly destructive, as in the collision that probably killed off the dinosaurs. Thankfully, the biggies are extremely rare.

Sagan makes the point that the most dangerous collision facing us now, however, is one that might be mistaken for something else: a nuclear attack. He warned that thinking an asteroid is actually an ICBM could result in the worst possible destruction–an unintended war.

Was this just paranoid thinking? Unfortunately, no. Carl Sagan is no longer with us, but in testimony before congress just last year, a United States Air Force brigadier general warned that just such a thing almost happened in June of two thousand and two. That’s when a meteoroid entered the earth’s atmosphere over the Mediterranean and was picked up by U.S. early-warning satellites on the lookout for high-altitude explosions and incoming missiles.

The alarming object falling from the sky was recognized for what it was, this time. The generals’ point, though, was that we never know where space junk will fall. Turn the globe by just a few hours earlier on that day in June and the meteoroid would have been over the border of Pakistan and India–exactly where everyone was fearing a nuclear attack.

We’ve been lucky so far. But Carl Sagan’s warning came perilously close to becoming a prophecy and a harmless natural event in the sky, to triggering a terrible event here on earth.

以上就是这篇托福阅读材料,同学们可以积累其中的词汇及优美句式,找到托福阅读段的主题句,了解托福阅读的几个出题点。托福阅读训练是个长期的过程。大家如果每天做几篇阅读,坚持下来,一定会有不小的进步。预祝大家能有一个好的阅读成绩。
