Squeaks and I love to race each other.
我和吱吱喜欢互相竞赛。
We can both move pretty quickly, so sometimes I win, and sometimes Squeaks wins.
我们跑得都很快，所以有时我赢，有时吱吱赢。
You're right, Squeaks! You did win the last race! You were really fast.
吱吱，你说对了！你上次赢了，跑得很快。
But there's another animal that's faster than both of us: the cheetah.
但另一种动物比我们都快:猎豹。
Cheetahs are big cats that live in Africa and Asia.
猎豹是生活在非洲和亚洲的大型猫科动物。
But even though they might look like huge kitties, these cats aren't like house cats at all.
但它们即使可能看起来像巨猫，但根本不像家猫。
They're wild animals, and they have an amazing super skill: they're incredible runners!
它们是野生动物，有惊人的超能力：它们是令人难以置信的奔跑者！
Cheetahs can run about 100 kilometers an hour, or 60 miles an hour.
猎豹的时速大约是100公里或60英里。
That's about as fast as a car driving on the highway!
它们跑得和高速公路上的汽车一样快！
They're so fast that they're the fastest runners on Earth, way faster than the fastest people can run.
它们的速度很快，是地球上速度最快的奔跑者，比跑得最快的人都快。
And there's another good reason they can run so fast!
它们跑得快还有另外一个充足的理由！
Cheetahs are predators, meaning that they hunt other animals for food.
猎豹是捕食者，也就是说它们捕食其他动物作为食物。
Their quick feet help them catch their next meal.
它们的快脚帮助自己捕捉下一顿饭。
Can you imagine having to run at top speed to catch your dinner?
你能想象自己不得不以最快的速度追赶你的晚餐吗？
You'd probably get tired pretty quickly.
你可能很快就会感到疲劳。
The same thing happens to cheetahs.
猎豹也是一样。
It's exhausting for them to run at full speed for more than a minute or so,
它们全速奔跑超过一分钟就会力竭，
so they'll only chase other animals in short bursts of speed.
所以它们只能短时间内速度爆发追逐其他动物。
Which means that to have the best chance of getting their food,
也就是说为了掌握获得食物的最佳时机，
cheetahs use other skills to get as close as they can to the animals they're hunting before they start chasing them.
在猎豹开始追捕猎物之前，它们会用其他技巧尽可能接近猎物。
One thing that helps is that cheetahs are covered in spots, which help them to camouflage, or blend in with the grass around them.
有一件事很有帮助，那就是猎豹身上布满斑点，这能帮它们伪装，或融入周围的草里面。
That camouflage can get cheetahs really close to an animal before they leap out to get it.
伪装能使猎豹在跳出来捕获猎物之前接近它们。
And cheetahs have another special talent:
猎豹也有另一种特殊的天赋：
while they're running, they're really good at changing directions quickly to stay close to the animals they're chasing.
当它们奔跑时，真得很擅长快速改变方向，以接近它们所追逐的动物。
They even have a special tail that helps them to steer as they run,
它们甚至有一条特殊的尾巴帮助它们在奔跑时转向，
turning in different directions to keep them from slipping and falling.
防止它们在向不同方向转动时滑倒。
And you know what else helps cheetahs sometimes, especially when they want to take down a really big animal, like a wildebeest?
你知道还有什么能帮助猎豹的吗，特别是当它们想要拿下角马一类的大型动物？
Teamwork! One cheetah will start chasing the wildebeest,
团队合作！一只猎豹开始追逐角马时，
and then another will come in from the other side while the wildebeest isn't looking.
另一只会从角马看不到的一边过来。
With two cheetahs working together, they can get a huge meal!
两个猎豹一起合作，就可以得到一顿大餐！
That's some impressive teamwork, isn't it, Squeaks?
这是一个有些令人印象深刻的团队合作，不是吗，吱吱？
So, running really fast can be a big help for cheetahs.
所以，快速奔跑对猎豹来说帮助很大。
But it does mean that they have some different needs than other predators.
但这确实意味着它们与其他捕食者有不同的需求。
Cheetahs each have their own hunting grounds where they find their food, so they aren't all trying to chase the same animals.
每只猎豹都有自己的猎场，它们在那里觅食，所以它们并不都在追逐同样的动物。
Since cheetahs run so far, so fast when they're chasing their prey,
因为猎豹追赶猎物时跑得很远，也很快，
they each need a huge hunting ground to avoid crowding the other cheetahs while they're hunting.
所以每个猎豹需要一个巨大的猎场，防止狩猎时与其他猎豹相撞。
If they had only a small space, a cheetah chasing a gazelle might run straight through the homes of a bunch of other cheetahs.
如果它们只有一个小空间，一只追逐瞪羚的猎豹可能会径直穿过一群猎豹的家。
Speaking of running fast, Squeaks, are you ready for our next race?
说到快跑，吱吱，你准备好迎接下一场比赛了吗？
OK, let's head outside!
好了，我们去外边吧！
Maybe the lessons from those cheetahs will help us go faster.
或许从这些猎豹身上得出的经验会帮助我们跑得更快。
Do you have any questions about cheetahs, or any other animal?
你对猎豹或其他动物有什么疑问吗？
How quickly can you run?
你能跑多快？
