（单词翻译）

Desert life is not only shaped by the scarcity¹ of water,

沙漠中不仅水源稀缺，

but also by the relentless² power of the sun.

更有炎炎烈日的残酷炙烤。

The highest temperatures on Earth have all been recorded in its deserts.

and as deserts heat up, they are also expanding.

随着温度升高，沙漠也在不断扩散。

Every year, a further 50,000 square miles of grass and farmland are turning into barren stretches of dust and rock.

In the heat of the day, surface temperatures can reach 160 degrees, far too hot to handle for most.

一天中最热之时，沙漠地表温度可达七十一摄氏度，大多数生物都无法忍受。

But not for this shovel-snouted lizard³.

但这只铲吻蜥蜴却可以。

Raising its feet off the ground in turn... enables each to briefly⁴ cool.

它将四肢轮流抬起，短暂降温一下。

But even this dancing desert specialist can't stand the heat for long.

One option is to find shade.

一个办法是寻找阴凉。
