下面带着对这些单词和短语的理解，尝试读一读下面的原文，看看是不是容易理解多了呢？

The Altiplano-Puna magma body is known to be around half a million cubic kilometres in volume, so the researchers estimate it must contain a similar amount of water to some of the largest freshwater lakes on Earth. “It’s probably somewhere between Lake Superior and Lake Huron,” says Blundy. “It’s a staggeringly large amount.”

Other anomalies with similar unexplained conductivity have been discovered beneath other volcanoes, such as those in the Taupo Volcanic Zone in New Zealand, and Mount St Helen’s in Washington State, which erupted spectacularlyin 1980. It’s likely that these are also signs of secret reservoirs.

“This study illuminates a new feature of Earth’s deep-water cycle, and reminds us how little we know about the pathway of water through Earth’s crust and mantle systems on geologic timescales,” says Steve Jacobsen of Northwestern University in Evanston, Illinois, whose team previously discovered a reservoir of water three times the volume of all the oceans 700 kilometres down in the mantle.

Such discoveries add to growing evidence that significant amounts of water exist in Earth’s interior, some of which may even have been the source of today’s oceans. It could be that the water that makes our planet habitable was present in the dust that coalesced to create Earth, rather than arriving later on ice-rich comets or asteroids.
