Hey there, everyone. Squeaks was just telling me about the big trip he's planning with Jesse.
大家好。吱吱正在跟我讲他和杰西计划的旅行。
It'll be his first time flying on an airplane.
这将是他第一次坐飞机。
He's pretty nervous. It's natural to be anxious before a big event.
他很紧张。在重大事件前感到焦虑是很正常的。
But we've been helping Squeaks find ways to feel less scared.
但我们一直在帮助吱吱寻找不那么害怕的方法。
I think it's great that you're learning all about how planes and flying work to help you feel less nervous about your first plane ride.
我觉得学习飞机以及飞行的原理是很好的，这样你第一次坐飞机时就不会那么紧张了。
But there are a lot more things on planet Earth that fly than just airplanes.
但是除了飞机，地球上还有很多东西会飞。
Can you think of some?
你能想到一些吗?
Huh, Sam the Bat, Dino, Bill and Webb?
蝙蝠山姆，迪诺，比尔和韦伯?
We do actually have a lot of friends with wings, don't we?
我们确实有很多长翅膀的朋友，不是吗?
Different kinds of animals like bugs, birds and bats all have wings.
不同种类的动物，比如虫子、鸟儿和蝙蝠都有翅膀。
And have you ever watched all those different kinds of animals fly?
你看过各种各样的动物飞翔吗?
They all look a little different when they fly, don't they?
它们飞起来的时候看起来都有点不一样，不是吗?
Let's check out some of the different ways animals use flight to get their bodies from one place to another.
让我们来看看动物使用飞行将身体从一个地方转移到另一个地方的一些不同方式。
This is a really big bird called an albatross.
这是一种非常大只的鸟，叫做信天翁。
They spend a lot of time soaring above the ocean.
这种鸟花很多时间在海洋上空翱翔。
What do you notice about its wings, Squeaks?
吱吱，你注意到它的翅膀了吗?
I think they look very long and skinny, a little like airplane wings, don't you think?
我觉得它的翅膀看起来又长又细，有点像飞机的翅膀，你不觉得吗?
Those big wings help them fly long distances to find the food they need.
这些大翅膀帮助它们远距离飞行去寻找所需的食物。
A little bit like the jet plane you're gonna fly on.
有点像你要坐的喷气式飞机。
These birds use their wings to move their bodies long distances.
这些鸟用翅膀将身体移动到很远的地方。
They travel a long way and for a long time because they're looking for food.
它们要长途跋涉很长时间，因为它们在寻找食物。
Their favorite foods like squid and animals called krill might be far apart on the surface of the ocean.
它们最喜欢的食物，比如鱿鱼和磷虾，可能距离海洋表面很远。
So the albatross has to move its body a long way to find the best food.
所以信天翁必须移动身体很长一段距离才能找到最好的食物。
In fact, one kind of albatross can fly around the whole world in just six weeks.
事实上，有一种信天翁可以在六周内环游世界。
What other kinds of flying things can you think of?
你还能想到其他会飞的动物吗?
Oh, yes, great idea. Bees have wings, too.
哦，是的，好主意。蜜蜂也有翅膀。
Although they're very different from an albatross's wings.
尽管它们和信天翁的翅膀很不一样。
What do you notice about the shape or structure of a bee's wings?
你注意到蜜蜂翅膀的形状或结构吗?
Yes, the wings of a bee are more short and stubby. And let's watch it fly.
是的，蜜蜂的翅膀更短更粗。让我们观看蜜蜂飞起来。
The albatross flies a long way while the bee makes lots of stops jumping from flower to flower.
信天翁飞可以远距离飞行，而蜜蜂从一朵花跳到另一朵花进行停歇。
The pollen and nectar in the flower are the bees main food and it has to visit lots of flowers.
花中的花粉和花蜜是蜜蜂的主要食物，蜜蜂必须落到很多花上。
So rather than traveling a long way, it might visit many flowers that are close together.
因此，它可能不会飞很远的路，而是会落在很多相近的花上。
If the albatross flies a long way like a jumbo jet, the bee is like a city bus making lots of stops.
如果说信天翁像大型喷气式飞机一样能飞很长一段路，那么蜜蜂就像一辆城市巴士，要停很多站。
They have to move their bodies in different ways to get food so they have different kinds of wings to help them do that.
它们必须以不同的方式移动身体来获取食物，所以它们有不同种类的翅膀来帮助它们这样做。
And what about penguin, Squeaks? Have you ever seen one fly?
吱吱，那企鹅呢? 你见过企鹅飞吗?
I haven't either. But they are a bird and they do have wings.
我也没有见过企鹅飞。但它们是鸟类，它们有翅膀。
They just don't use their wings to fly in the air.
它们只是不用翅膀在空中飞翔。
Penguins use their wings to move themselves through the water.
企鹅用翅膀在水中移动。
Scientists think it's a lot like other birds flying through the air since the penguins use their wings in a similar way.
科学家们认为这很像其他鸟类在空中飞行，因为企鹅使用翅膀的方式很相似。
Let's look at a penguin's wings.
让我们看看企鹅的翅膀。
See how their wings are flat almost like the petal of a boat.
看看它们的翅膀多扁平，几乎像船桨一样。
That shape or structure is good at moving the penguin through the water.
这种形状或结构有利于企鹅在水中移动。
It flaps its wings to swim and that moves the penguin through the water, just like other birds flap their wings to move through the air.
企鹅扇动翅膀游泳，这让企鹅在水中移动，就像其他鸟类扇动翅膀在空中移动一样。
Why do you think penguins need to fly in the water instead of air, Squeaks?
吱吱，你为什么认为企鹅需要在水中游行而不是在空中飞行?
Yes, the penguin's food is fish so the penguins have to move their bodies under water to catch their food.
是的，企鹅的食物是鱼，所以企鹅必须在水下移动身体来捕捉食物。
Wow, Squeaks, there sure are a lot of different creatures that use their wings to move their bodies where they need to go, aren't there?
哇，吱吱，确实有很多不同的生物用翅膀来移动他们的身体，不是吗?
It's pretty amazing to think of all the different animals that rely on flying to get them where they need to be
想想所有不同的动物都依靠飞行来到达它们需要到达的地方，
and the different ways they move their bodies from one place to another using flight even underwater in some cases.
它们用飞行的不同方式将身体从一个地方移动到另一个地方，甚至在某些情况下在水下也是如此。
What types of animals can you think of that use flight to get them from place to place?
你能想到哪种动物会用飞行从一个地方飞到另一个地方?
What other types of wings can you think of?
你还能想到别的类型的翅膀吗?
How do those wings help the animal get what it needs from its environment?
这些翅膀如何帮助动物从环境中获得所需的东西?
