英语听力：自然百科 澳大利亚大堡礁 Great Barrier Reef—8

 For thousands of years, this powerful current has regenerated¹ the reef. But it can not repair everything. Beneath the waves lie deeper scars—the largest coral reef on Earth is home to a dazzling diversity of marine² species, some found nowhere else on the planet. 

 

It’s a panorama³ of alien shapes and riotous⁴ color, where even the flamboyant⁵ mandarin⁶ fish can blend in. These coral gardens are home to armored reptiles⁷, and the softest of killers—the cone⁸ shell and the blue-ringed octopus⁹, delicate, graceful¹⁰ and with enough venom¹¹ to kill two dozen people. 

 

While above glide¹² giants—manta ray and wandering minke whales, it is the most diverse ecosystem¹³ known to man. But this world used to be very different, where fish now swim, birds once flew. And this whole forest of coral was once a tangle¹⁴ of trees and bushes. 

 

And this man can prove it. On a remote part of Australia’s coast, geophysicist Thomas Stieglitz is looking for the last thing you’d expect to find in the ocean—freshwater. 

 

"We’re on our way to a beach way up north. It’s in an aboriginal¹⁵ community, where people have told us that there’s a lot of springs on the beach. Well, if there’s water out there, where do you expect this water to come from? How does it actually get out there?"

 

"I think somewhere around here, there’s supposed to be a pretty big one. Just trying to find it. It’s actually quite a treacherous¹⁶ job. What we call quicksand, actually on beaches, can actually fall into that, cos it's such soft sand."
