I need to find a cool place to rest

Look, there's a hole in the ground. I'll rest there

旁白 neutral

Who are you?

Oh, I'm sorry. I am a sparrow

旁白 neutral

This desert is so dry and hot that I did not expect to see any animals living here!

这个沙漠又干又热，我没想到会在这里看到有动物生活！

旁白 neutral

I am a desert mouse, and there are a lot of animals here

我是一只沙漠鼠，这里有很多动物。

旁白 neutral

Really?

真的吗？

旁白 neutral

Yes. The days are very hot and dry, but the nights are cold

是的。白天又热又干，但晚上很冷。

旁白 neutral

So most desert animals do not move around during the day

所以大多数沙漠动物白天不活动。

旁白 neutral

But how do they endure so much heat?

但它们怎么忍受这么热呢？

旁白 neutral

It is so hot that I am about to die!

热得我快要死了！

旁白 neutral

Well, some desert animals use parts of their bodies to cool off

嗯，有些沙漠动物用身体部位来降温。

旁白 neutral

For example, desert owls open their mouths wide and flutter their throats

比如，沙漠猫头鹰张大嘴巴，扇动喉咙。

旁白 neutral

The jackrabbit's ears are long and have many blood vessels

长耳大野兔的耳朵很长，有很多血管。

旁白 neutral

The heat is released through the blood vessels in its long ears

热量通过长耳朵里的血管散出去。

旁白 neutral

Oh, that's interesting!

哦，真有趣！

旁白 neutral

Up north, I have seen other rabbits, and their ears are much shorter

在北方，我见过其他兔子，它们的耳朵短得多。

旁白 neutral

Yes, up north, they do not need long ears to survive

旁白 neutral

All over the world, animals are suited to their different habitats

世界各地，动物都适应各自不同的栖息地。

旁白 neutral

For example, most desert animals are light-colored

例如，大多数沙漠动物都是浅色的。

旁白 neutral

Their lighter colors keep them from getting really hot too

浅色也能防止它们变得太热。

旁白 neutral

Then what about the darker animals?

那深色的动物呢？

旁白 neutral

They would get much hotter than light-colored animals. Right?

它们会比浅色的动物热得多，对吧？

旁白 neutral

You are right. Vultures are dark-colored, but they wet their legs with their urine

你说得对。兀鹫是深色的，但它们会用尿液弄湿腿。

旁白 neutral

The urine cools the blood in their legs

尿液能冷却腿部的血液。

旁白 neutral

The cooler blood goes back through their bodies

冷却后的血液再流回全身。

旁白 neutral

I see. They are really amazing!

原来如此。它们真了不起！

旁白 neutral

Then how do desert animals find water?

那沙漠动物怎么找水呢？

旁白 neutral

You do need water, don't you?

你也要喝水，对吧？

旁白 neutral

Of course! We desert creatures get water from plants

当然啦！我们沙漠动物从植物里获得水分。

旁白 neutral

The juicy cactus is a favorite! Have a piece!

多汁的仙人掌是最受欢迎的！来一块吧！

旁白 neutral

But won't I get stuck by the thorns?

可我不会被刺扎到吗？

旁白 neutral

Not really. Go ahead, just be careful

一般不会。来吧，小心点就好。

旁白 neutral

Hmm, not bad! By the way, how do you stay cool in this desert?

嗯，不错嘛！对了，你在沙漠里怎么保持凉快？

旁白 neutral

I live in an underground den like this

我住在这样一个地下洞穴里。

旁白 neutral

I close the opening when it is very hot

天气特别热的时候，我会把洞口封起来。

旁白 neutral

That keeps out the heat

这样就能把热气挡在外面。

旁白 neutral

Then I can save the moisture from my breath

还能保住我呼出的水分。

旁白 neutral

Wonderful! Desert animals are really amazing

太棒了！沙漠动物真了不起。

旁白 neutral

But I might not survive here

不过我在这儿可能活不下来。

旁白 neutral

That's true. The desert gets very little rain

那倒是。沙漠里雨水很少。

旁白 neutral

It gets less than 25 centimeters of rain a year!

一年降雨量还不到 25 厘米！

旁白 neutral

So all the animals in the desert have special ways to help them survive
