英语课

   These are volcanoes so explosive that they burst open in a single mighty 1 rupture 2, leaving behind a vast subsided 3 pit, the caldera (from a Latin word for cauldron). 这种火山的威力如此之大,它们一下子破土而出,留下一个沉降式大坑,即破火山口(源自拉丁语,意思是大锅)。


  Yellowstone obviously was of this second type, but Christiansen couldn't find the caldera anywhere. 黄石火山显然属于第二种,但克里斯琴森哪里也找不到那个破火山口。
  By coincidence just at this time NASA decided 4 to test some new high-altitude cameras by taking photographs of Yellowstone, 恰好在这个时候,美国国家航空和航天局决定拍摄黄石公园的照片,测试一下某些新型的高空照相机。
  copies of which some thoughtful official passed on to the park authorities on the assumption that they might make a nice blow-up for one of the visitors' centers. 一位考虑周到的官员把其中的有些照片交给了公园当局,认为它们可以挂在某个游客中心。
  As soon as Christiansen saw the photos he realized why he had failed to spot the caldera: virtually the whole park—2.2 million acres—was caldera. 克里斯琴森一看到这些照片,马上意识到他没有找到破火山口的原因:实际上,整个公园——9000平方公里——就是破火山口。
  The explosion had left a crater 5 more than forty miles across—much too huge to be perceived from anywhere at ground level. 火山爆发留下了一个直径将近65公里的大坑——大得从地面上的任何角度都看不明白。
  At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans. 过去某个时刻,黄石公园可能被炸得七零八落,威力之大远远超过了人类已知的任何等级。
  Yellowstone, it turns out, is a supervolcano. 结果发现,黄石公园是一座超级火山。
  It sits on top of an enormous hot spot, a reservoir of molten rock that rises from at least 125 miles down in the Earth. 它坐落在一个巨大的热点——一个熔岩储藏所——之上。这个储藏所下达地球至少200公里深处,上至接近地面的地方,形成了一根所谓的超级热柱。
  The heat from the hot spot is what powers all of Yellowstone's vents 6, geysers, hot springs, and popping mud pots. 热点的热量为黄石公园里所有的喷气口、间歇泉、温泉和冒泡的泥坑提供了动力。
  Beneath the surface is a magma chamber 7 that is about forty-five miles across, 地面以下是个岩浆房,直径约为72公里,
  roughly the same dimensions as the park—and about eight miles thick at its thickest point. 大致相当于公园的大小,最厚的地方达13公里左右。
