英语听力：自然百科 探索世界奥秘之Wild Africa - Deserts(浩瀚沙漠) Unit15

Arabian camels and nomadic¹ people are the most recent in a long line of Saharan pioneers. The history of this great region is told in ancient rock art, glimpses of a vanished world. Just a few thousand years ago, this desert was still wet enough to support great herds² of cattle and goats. Prey³ was abundant, and people used horse-drawn chariots, dogs, bows and arrows in the hunt for food. Giraffes, elephants, buffalo⁴, lions and rhino⁵ roamed across the Sahara. There are rivers full of fish, even crocodiles.

Today at Ennidi Gorge⁶, there are living reminders⁷ of that once green Sahara. In a few isolated⁸ oasises, there are still an abundance of aquatic⁹ life. Even more surprising is that these communities of fish still support a dwindling¹⁰ number of Nile crocodiles. They are the last survivors¹¹ of a once healthy population which over thousands of years has been left high and dry by the changing climate. Today, just three crocodiles remain, too few to continue the line marooned¹² by hundreds of miles of sand, right in the middle of the mightiest¹³ desert on earth.

Africa's deserts are more than just barren expanses, they are dynamic worlds, each with its own unique character. They are also places of great opportunity, where given enough time, a steady climate and a sprinkle of water, life can flourish, and it has done so in some of the most extraordinary ways imaginable.
