英语听力：自然百科 探索世界奥秘之Wild Africa - Deserts(浩瀚沙漠) Unit04

With the spider exposed, it's now a battle between the wasp¹'s paralyzing sting and the spider's jaws². But the wasp has quick reflexes. Cornered, the spider now plays its trump³ card. Hurling⁴ itself down the dune⁵, it flips⁷ into a wheel. Traveling at over 40 turns a second, it makes a dizzy dash for freedom. Safe, at last.

Back up the dune, the wasp is left standing⁸, chasing the scent⁹ of its vanished meal.

Instinct honed over time, governs much of the life in the Namib. But some creatures also have to learn how to conquer these sands, using knowledge passed down over generations.

African elephants are so resourceful, they can survive even here in the heart of the desert.

Elephants have remarkable¹⁰ powers of memory. Though this desert is more than 2 million square kilometers in size, 100 or so elephants it supports know precisely¹¹ where to find enough to eat and drink. It takes a lot of food, up to 300 kilos a day to feed the world's largest land animal. And all of that -from a desert.

But there's one plant here, the Nara, whose roots draw water from deep underground. Each year it produces a bumper¹² crop of melons. Elephants just love them.
