英语听力：自然百科 走进西藏 tibet—6

 In this rugged¹ and unforgiving terrain² littered with fractured rock and ice-cold rivers, the slightest miscalculation may have fatal consequences. The snow leopard³ is the world’s highest living big cat. But there’s another smaller predator⁴ that ranges even higher, almost to the roof of the world. At a mind-numbing 8,848 metres high, Everest is one of the most hostile places for life on Earth. Hundreds of people have died trying to conquer it. But when climbers first reached the ice fields three quarters of the way up the mountain, something had already beaten them to it. 

 

This jumping spider is the highest permanent resident on the planet. Totally at home amongst the glaciers⁵ of Everest, it scours⁷ the slopes for wind-borne prey⁸ such as springtails. Chinese call this fierce little hunter the “fly tiger”. Jumping spiders are found all over the world. Their eight eyes include an oversized central pair, which act like powerful binoculars⁹ to spot potential victims. They use hydraulic¹⁰ pressure to work their legs like pistons¹¹, catapulting up to 30 times their own body length. The ideal way to get around in rocky terrain. But like all mountaineers, they always secure a safety line first. A springtail grazes on the detritus¹², unaware¹³ that it’s been stalked by such an acrobatic predator. 

 

The Tibetans call Everest “Qomolangma”, meaning mother of the world. It’s a mark of their affection for the mountain, however brutal¹⁴ it may appear. Venture further from the mountain and out  onto the open plateau and life doesn’t appear to get any easier. High winds scour⁶ the landscape and temperatures can drop from baking to freezing in moments. 

 

This is the Chang Tang, or Northern Grassland¹⁵. It’s so remote that it’s been called a third pole.
