Squeaks and I were just learning about a really cool animal!
我和吱吱刚刚在了解一种非常酷的动物！
See if you can guess what it is:
你能猜到它是什么吗？
It's really big...it has four legs...a little tail...and a big horn on its nose...
它的体型很大...有四条腿...小尾巴...鼻子上有巨大的角...
That's right! It's a rhinoceros, or rhino for short!
猜对了！它就是犀牛！
They're such awesome animals! But there aren't a lot of them left in the world.
它们是很了不起的动物，但世界上所剩不多;4L!4vy7yf@1I2~。
Did you know that there's more than one type of rhinoceros?
你知道犀牛不只一种吗？
It's true! There are 5 types of rhino, and they all live in either Africa or Asia.
这是真的，犀牛有5个类型，它们都生活在非洲或亚洲;f|lpJxyi7S6aF。
But all rhinos have a few things in common: for starters, they're huge!
但所有的犀牛都有几个共同点：第一个，它们体型巨大！
The white rhino, which lives in Africa, is the biggest type of rhino.
生活在非洲的白犀牛体型最大，
A white rhino can weigh more than 2,000 kilograms, that's heavier than a car!
一头白犀牛重达2000多公斤，比一辆汽车还重！
Even the smallest type of rhino, the Sumatran rhino, can weigh close to a thousand kilograms.
即使是最小型的苏门答腊犀牛，体重也接近1000公斤了7RtJ%~Hset@k。
And they can live for a long time!
它们的寿命很长！
In the wild, a rhino can live between 45 and 50 years old.
在野生环境下，犀牛的寿命在45到50年之间qB_a,NEfU[。
Rhinoceroses are also herbivores, which means they only eat plants, like fruits and grass.
犀牛是食草动物，这意味着它们只吃水果或草之类的植物XWGgb7CSxAo(o。
Some rhinos even knock down whole trees, so they can get to the leaves and twigs at the top.
有些犀牛甚至撞倒整棵树，只为吃到其顶部的树叶和树枝%Od4__p7[t5Ysnw|l2。
What's another thing that all rhinos have in common?
犀牛还有其他的共同点吗？
Here's a hint: it's pretty easy to see when you look at them.
提示一下：你看它们时很容易就能发现N0cty#vLpjOcQ7。
That's right, Squeaks! They all have those big horns on their noses.
吱吱，说对了！它们的鼻子上都有巨大的角uZ,W9hqm36dC!Wan1L0。
Rhinoceros horns are made of a material called keratin, which is the same stuff that your hair and fingernails are made of!
犀牛角是由一种叫做角蛋白的材料构成的，这与你头发和指甲的构成相同BhNs9;g=g.。
Some rhinos, like the black rhino, have two horns, and some, like the Javan rhino, have one.
一些犀牛如黑犀牛有两个角，有些犀牛如爪哇犀牛，有一个角gGI6WNy.rmPwfa。
Rhinos use their horns to protect their babies from predators
犀牛角用来保护自己的孩子免受捕食者的伤害，
and to defend their territory, or the place where they live, from other rhinoceroses.
也用来捍卫自己的领土或栖息地，免受其他犀牛的侵犯8Oz7xs7~c.]=]4g][xZ。
Most types of rhinos live alone or with their babies, which we called calves, and each rhino has its own territory.
大多数类型的犀牛都是独居或与它们的宝宝(calves)一起生活，每头犀牛都有自己的领地]=_RhYu#6QaH。
And they mark the edges of their territory in a fun way: with their poop!
它们标记领地边缘的方法很有趣：用粪便标记！
A rhino will pick a few places around the outside of their territory where they will always go to poop.
犀牛会在它们领地之外挑选一些地方，它们总去那里大便=4qKV~T(nkJS7#Q-UND。
And when they're done, the rhino will kick the poop around, spreading a smell in the air that tells other rhinos to stay away!
它们大便完后，把便便踢翻，让气味散发到空气中，来告诉其他犀牛远离此地！

There's one more thing that most rhinos have in common:
大多数犀牛还有一个共同点：
almost all types of rhinos are endangered, meaning that there aren't a lot of them left.
几乎所有类型的犀牛都濒临灭绝，所剩无几F2dDkt@)2vfE%Ls%T;(。
There are only about 50 Javan rhinos left, and they all live in one small part of Indonesia.
现在只剩下大约50只爪哇犀牛了，它们都生活在印尼的一小部分地区Z+(FpI^2^4R4E。
Someday, most types of rhinos might go extinct, meaning there won't be any alive at all.
可能有一天，世界上大多数类型的犀牛都会灭亡，不会再有活犀牛了FD0SJaMyJ-if_2_4Djy。
Other animals don't really attack rhinoceroses, but they're still in danger for two main reasons.
其他动物并没有真正攻击犀牛，但因为两个主要原因，它们仍然处于危险之中X9,]p#8x|8。
One reason is that they don't have as many places to live anymore,
一个是它们的栖息地不够了，
because people keep destroying the habitat where they used to live.
因为人们一直在破坏它们过去居住的栖息地fB2d0)^QPP。
Another problem is that some people hunt and kill rhinos because their horns are worth a lot of money.
另一个问题是一些人因为犀牛角的巨大利益而捕杀犀牛ZzOV5m,J)6%~xi。
But a lot of people are trying to help the rhinos in different ways,
但也有许多人试图用不同的方法来帮助犀牛，
like making it illegal to hunt them and protecting the places where they live.
如规定狩猎犀牛是非法的，保护它们的栖息地等7rCrwx@a5X=l。
And in some places, it's working!
在一些地方，这些方法起作用了！
Black and Indian rhino populations are slowly growing again.
黑犀牛和印度犀牛的数量再次缓慢增长BrXxEn%5%^9ng3GB。
But for other types of rhinos, like the Javan rhino, there's still lots of work to do if we want to keep these amazing animals around.
但爪哇犀牛等其他种类的犀牛，仍需要我们做大量的工作来保护它们存活下来%6%+vJ|Vj]WT%4%v!vv。
And the best way that you can help is to learn as much as you can about them.
你能帮它们的最好方法就是尽可能多地了解它们0O+]~(Q4j7。
