How would you like to play a game of True or False?
你想玩真假游戏吗?
Squeaks and I came up with a really fun game
我和吱吱想出了一个非常有趣的游戏，
where you're goin' to guess what's true and what's not about one of our favorite kinds of animals, snakes!
对一种我们非常喜欢的动物——蛇的描述，猜猜真假。
Snakes are super interesting, and there are lots of different kinds!
蛇非常有趣，而且有很多种。
Scientists think there are more than 3,500 different types of snakes in the world!
科学家们认为世界上有3500多种不同的蛇。
The smallest is about as thin as a piece of spaghetti, and can curl up comfortably on a quarter.
最小的蛇像意大利面一样细，而且可以舒服地蜷缩在一个两角五分的硬币上。
But another kind, called a python, can grow to be about ten meters long,
另一种叫做巨蟒的蛇，可以长到约10米长，
which is just a bit shorter than a school bus!
仅比校车短一点儿！
Some snakes are brightly colored, while others blend in really well to their environments.
一些蛇色彩艳丽，而另一些能与环境完美地融合。
But there are a few things that a lot of people including kids,
但很多人包括小孩
tend to think about snakes that they're just not true!
对蛇类的某些认知是错误的。
So, we came up with this awesome game, so you can learn the facts about these amazing animals!
所以，我们想出了一个不错的主意，让你可以了解这些神奇动物的真相！
Okay, here's how it works!
好了。我们看看游戏是怎么玩的吧！
I'll say something about snakes, and you and Squeaks can guess if it's true or false!
我会说蛇类的某件事，你和吱吱可以猜它的真假！
Ready? Alright! Number one! Snakes are slimy and squishy. True or false?
准备好了吗？好了，第一个问题：蛇黏滑湿软，对还是错？
You're right, Squeaks, false!
吱吱，你猜对了，这是错的！
All snakes belong to a group of animals called reptiles.
所有的蛇都属于爬行动物。
Like all reptiles, snakes have skin that's covered with scales to help protect them.
和所有爬行动物一样，蛇的表皮覆盖着鳞片来保护它们。
Touch your fingernail.
摸摸你的手指。
How does it feel? Snake scales feel a lot like that!
什么感觉？蛇鳞的感觉和它非常类似！
That's because scales are made of the same stuff as your fingernails and toenails!
这是因为蛇鳞的构成物质与你手指甲和脚趾甲的物质形同。
So scales feel hard, and most of the time pretty smooth.
所以鳞片感觉很硬，大部分时间很光滑。
Which means that a snake doesn't feel slimy at all! It feels dry!
这意味着蛇根本不黏滑。它感觉是干的！
But are snakes squishy like a worm? Nope!
但蛇和虫子一样是湿软的吗？不是！
All reptiles, including snakes, also have something else, a skeleton made of bones.
所有的爬行动物包括蛇，也有其他东西——骨头构成的骨架。
In fact, a snake's skeleton has a lot of the same parts that our skeletons have.
事实上，蛇的骨架和我们的骨架有很多相同的部分。
Can you reach around and touch the middle of your back?
您能伸手摸到后背的中间吗？
If you can, then you should be able to feel hard bumps that run from the top of your neck all the way down.
如果做到的话，你就能感觉到坚硬的隆起，它们从你的脖子顶端一直往下延。
These bumps are caused by the bones that make up your backbone.
这些隆起是由构成脊椎的骨头造成的。
Muscles inside your body connect to your backbone,
你身体的肌肉与脊椎相连，
and help you do all kinds of things, like stand up, bend over, and sit down.
帮助你做各种各样的事情，如站立、弯腰和坐下。
A snake has a backbone, too! And it does the same job as your backbone.
蛇也有脊椎！它和你的脊椎作用相同。
It works with a snake's muscles to help it move.
它与蛇的肌肉配合帮助蛇移动。
The way a snake moves is really cool, and it has a name that's kind of fun to say: slithering.
蛇移动的方式很酷，它有一个有趣的名字：滑行。
So, having a backbone means that snakes aren't soft and squishy like worms.
所以，蛇有脊椎意味着它不像虫子那样是柔软黏滑的。
Even though worms and snakes have a shape that looks kind of the same, they're not the same kind of animal.
即使虫子和蛇的形状几乎相同，但它们不是同种动物。
Worms don't have a skeleton, or a backbone.
虫子没有骨架或脊椎。
So worms don't slither, they wriggle, or crawl.
所以虫子不能滑行，它们蠕动或爬行。
Ok, let's move on to question Number Two in our game: Snakes attack and chase people. True or false?
好了，我们开始第二个问题：蛇攻击和追赶人类，是真还是假？
You're right, Squeaks! That's false, too.
你说对了，吱吱，这也是假的。
You might have heared people say that snakes are aggressive, which means they'll attack or chase people.
你可能听人们说过蛇具有侵略性，这意味着它们攻击或追赶人类。
But that's not true.
但这不是真的。
Snakes are usually pretty shy, and most of the time, they'll slither away to hide when people are around.
蛇通常很害羞，当周围有人时，它们大部分时间都会滑走藏起来。
But they will bite if they are afraid or if they can't get away to hide.
但它们如果感觉害怕或不能离开躲藏起来时就会咬人。
So, if you do see a snake, you don't need to run away.
所以，如果你看到一条蛇，不必跑掉。
But you should leave them alone and give them lots of space.
但你应该让它们独处，给它们很多空间。
Ok, let's do one more question. Number Three: Snakes are important. True or false?
好了，再做一题。第三题：蛇很重要，是真还是假？
This one is definitely true! Snakes are very important animals.
这当然是真的！蛇是一种非常重要的动物。
Snakes eat other animals, and many of those animals that they eat are ones that can sometimes cause problems.
蛇吃其他动物，它们吃得很多动物都会造成麻烦。
Snakes might eat baby insects like mosquitos…
蛇可能吃小昆虫如蚊子...
...or slugs that can eat the flowers and vegetables that grow in our gardens…
或者吃蛞蝓，后者会吃长在花园的花朵和蔬菜。
They can even eat mice, rats, and other small animals that sometimes carry diseases.
它们甚至吃老鼠和其他有时携带疾病的小动物。
Sorry, Squeaks! But you're safe! Snakes don't eat robot rats!
吱吱，对不起。但你很安全，蛇不吃机器鼠！
I want you to imagine what might happen if snakes weren't around to eat some of these animals.
我想让你想象一下，如果周围没有蛇来吃这些动物会怎么样。
There would be more and more of them...and the problems they cause would get bigger too!
这些动物会越来越多，它们导致的问题也会更严重！
So having snakes around helps keep an environment in balance.
所以周围的蛇能帮助保持环境平衡。
And an environment that's in balance is good for all living things, including people!
环境平衡对所有生物包括人类都有益！
So, if you're lucky enough to see a snake when you're out and about, you don't need to be afraid of it.
所以，你如果外出够幸运得遇到一条蛇，不必害怕它。
In fact, you might want to give it a wave and tell it "thank you"!
事实上，你可能想向它挥挥手，说声“感谢”！
