关于蝙蝠的3件趣事

3 Fun Facts About Bats!

我正在想一种动物。它很小,而且毛茸茸的。它非常可爱。
I’m thinking of an animal. It’s small, and furry. It can be pretty cute. And it flies
它在夜间飞行。
around at night.
你能猜到是什么动物吗?
Can you guess what animal it is?
没错,我想的就是蝙蝠。
That’s right! I’m thinking about bats!
一些人认为蝙蝠是可怕的,可能因为它们之间夜间出来。或者是因为
Some people think bats are scary. Maybe because they only come out at night. Or maybe because
有时它们生活在黑暗的地方。或者因为有些品种的蝙蝠,
sometimes they live in dark places. Or maybe it’s because some species of bats, called
吸血蝙蝠,它们靠喝血生存。
vampire bats, survive by drinking blood.
但是你可能从来没遇到过吸血蝙蝠。只有三种蝙蝠是饮血的。
But you probably won’t ever run into a vampire bat. Only three species of bat are blood drinkers.
其他的,超过1200种蝙蝠,它们吃水果,花蜜,小虫和其他小动物。
The rest of them, over 1,200 species, eat fruit, nectar, bugs, and other small animals.
在我们看来,蝙蝠总的来说还是很棒的!这里有三种我们最喜欢的事情
If you ask us, bats are totally awesome! Here are just three of our favorite things about
关于这些蝙蝠们。
them!
首先,一些蝙蝠能够在黑暗中听到路!
To start, some bats can hear their way in the dark!
那是因为,它们不像我们一样依靠眼睛。相反,这些蝙蝠
That’s because they don’t rely on their eyes, like we do. Instead, these bats use
通过声音来找它们周围的路。
sound to find their way around
你曾经对着一个空的大房间或者峡谷叫喊,并且听到你自己的声音
Have you ever yelled into a big empty room, or a canyon, and heard your own voice shout
回响吗?
back at you?
那叫做回声。你的声音穿过房间,到达墙上,
That’s called an echo. The sound of your voice moves across the room, to the walls,
然后反射到你的耳朵里。
and then bounces back to your ears.
这和蝙蝠在夜间飞行是非常相似的。它制造出一种声音,
And as a bat flies through the night, it does something really similar. It makes a sound,
然后仔细辨别回声。
and then carefully listens for the echo.
这个回声返回的方式告诉蝙蝠它的周围有什么东西。这个特别的
And the way the echo comes back can tell the bat a lot about what’s around it. This special
技能叫做回声定位。
skill is called echolocation.
如果回声返回的速度快,那意味着有东西距离它非常近。
If the echo comes back quickly, that means there must be something pretty close to it,
因为在回声反射前,这个声音只经过了非常短的距离。
because the sound only traveled a short way before bouncing back.
但是如果这个声音反射的回声经过了很长时间,这个蝙蝠就会知道
But if the echo takes a long time for the sound to bounce back, then the bat knows that
这个物体的距离比较远。
the object is further away.
蝙蝠不仅能辨别物体的距离,而且能辨别它的大小和速度。
Bats can tell not only how far away something is, but also how big it is, and how fast it’s
全部通过回声定位。
moving, all from using echolocation!
蝙蝠除了经常通过回声定位来辨别它们周围的世界,你也
And since bats are constantly using echolocation to figure out the world around them, you’ll
会经常看到他们张着嘴巴飞行,来保持声音的反射。
often see them flying around with their mouths open, to keep making sounds to bounce back.
关于蝙蝠我们喜欢的另一件事?它们非常喜欢悬挂着!
Another thing we like about bats? They really like to hang out!
蝙蝠们倒挂在安静的,黑暗的,隐蔽的地方,像是山洞的顶部或者
Bats hang upside down in quiet, dark, hidden places like the roof of a cave or the underside
桥的下面。
of a bridge.
但怎么做到的呢?当我倒挂在单杠上时,不久我就开始感觉
But how? When I hang upside down from the monkey bars, after a while I start to feel
我的头要爆炸了一样。
like my head’s going to explode!
蝙蝠能挂在那很长时间,是因为它们的身体生来就是能倒挂的!
Bats can hang for a long time, because their bodies are built for life upside down! The
在它们身体里有个血液流经的小通路,叫做动脉,
little pathways in their bodies that blood moves through, called arteries, have special
它们的特殊价值在于只让血液单向流动。
valves in them that only let blood through one way.
随着蝙蝠心脏的跳动,血液不得不单方向的在身体里流动。
As the bat’s heart beats, the blood has to keep moving through its body in just one
这使得血液被困在蝙蝠的头部,当它们
direction. That keeps the blood from getting stuck in the bat’s head when it’s hanging
倒挂时。
upside down.
这是相当灵巧的技能。但是你知道另外一个对于
That’s a pretty neat trick. But you know another thing that’s easy to like about
蝙蝠来讲很简单的事情吗?
bats?
它们绝对是非常伟大的妈妈。
They make really great moms.
一年里,蝙蝠通常只有一个叫做仔仔的宝宝,
Bats usually have one baby, called a pup, in a year.
仔仔刚生下来时,它会一直贴着妈妈的腹部,
At the beginning of a pup’s life, it clings to its mother’s belly all the time, while
当妈妈用翅膀环绕着她时。
the mom wraps her wings around it.
或许我们应该停止称呼这种依偎叫做“熊抱”,开始称作
Maybe we should stop calling good snuggles “bear hugs” and start calling them “bat
“蝙蝠抱”!
hugs”!
成千上万的妈妈和它们的宝宝们生活在一个被叫做温床的大团体里面。
And thousands of moms and their pups can live together in a huge group, called a nursery.
当外面寒冷的时候,这个温床开始变暖和,因为所有的蝙蝠
Even when it’s cold outside, the nursery stays warm, because of all those bats hanging
都紧密的悬挂在一起。
close together.
另外,当妈妈需要外出觅食时,它可以将孩子留在那个温床
Plus, when mom needs to go out to find food, she can just drop her baby off at the nursery
和其他的妈妈宝宝们待在一起。
with the other moms and pups.
当它回来时,你可能会认为它又该不好找到它的宝宝了。我意思是,
When she comes back, you might think it’d be hard to find her baby again. I mean, there
这里有成千上万的宝宝看起来都和它的一样。
are thousands of pups that look just like hers!
但是蝙蝠和它们的宝宝可以通过它们的气味和声音来辨识出对方。
But bats and their pups can recognize each other by their smells and their voices. So
所以当宝宝叫喊时,妈妈能准确的飞向它。
when a pup calls out, the mom can fly right to it
这就像是你在一个拥挤的娱乐公园中间寻找你的家庭,
It would be like trying to find your family in the middle of a crowded amusement park,
除非公园里的其他所有孩子们也叫喊着寻找他们的父母!
except all of the other kids at the park are calling out for their parents, too!
所以你怎么看?蝙蝠可怕冷酷吗?它们拥有超级感性能力,它们能
So what do you think? Aren’t bats scary-cool? They have super sensing abilities, they can
倒挂,它们是了不起的妈妈。
hang out upside down, and they’re marvelous moms.
对于动物们或者其他东西你有什么问题吗,你想要知道的更多吗?
Do you have a question about animals, or anything else, that you’d like to learn more about?
