20,000幀/秒下的鳥類起飛（213毫秒）- Smarter Every Day 197：英語精讀講義

Hey, it's me Destin.

Sorry for the vertical video there.

抱歉影片是直式的。

I was recording for the Instagram story.

我當時在錄 Instagram 限時動態。

So,

所以，

I caught this bird with my hand

我用手抓住了這隻鳥

and I got to thinking about it. 片語搭配

然後我就開始琢磨了。

It's kind of a shame to have a bird and let it go 講解

抓住一隻鳥然後直接放走，

and not film it in slow motion.

不拍個慢動作，感覺有點可惜。

So, that's what we're going to do. 文法

所以，我們這就來拍一下吧。

All right,

好了，

this is my daughter's butterfly thing.

這是我女兒裝蝴蝶的籠子。

Where are you at,

你在哪兒啊，

little bird?

小鳥？

Hey.

嘿。

Calm down, buddy.

冷靜點，小傢伙。

Calm down.

冷靜點。

Calm down.

冷靜點。

Let's go let you go.

我們這就放你走。

What do you think?

你覺得呢？

So, I have always been fascinated by birds.

我一直對鳥類很著迷。

Their wings in particular, 片語搭配

特別是牠們的翅膀，

you see their primary feathers, 用詞

你看牠們的初級飛羽，

1 2 3 4 5 6 7 8 9.

1 2 3 4 5 6 7 8 9。

I thought they had 10 primary feathers.

我原以為牠們有 10 根初級飛羽。

Maybe they do.

也許確實有吧。

And then these are the secondary feathers.

然後這些是次級飛羽。

And then the feathers around his eyes.

還有牠眼睛周圍的羽毛。

It's really cool.

真的很酷。

He's scared.

牠很害怕。

So, we're going to try to

所以，我們要試著

we're going to try to get him out of here real quick. 用詞

我們要試著趕緊把牠放出去。

He'll want to fly away.

牠會想飛走的。

I know this isn't like a super in-depth Smarter Every Day video,

我知道這不是一期非常深入的 Smarter Every Day 影片，

but this is just a target of opportunity, 慣用語

但這只是個碰巧的機會，

something to learn really quick.

能快速學到點東西。

What I want to know is when he takes off 片語動詞

我想知道的是，當牠起飛時，

if his tail feathers are correcting immediately

牠的尾羽是否會立即進行修正，

or if it has to wait until he's moving in flight before he starts using those.

還是說牠必須等到在飛行中移動時，才會開始使用尾羽。

We probably won't see that

我們可能看不出來，

because we literally have one shot to do this. 慣用語

因為我們實際上只有一次機會。

But uh I'm really excited.

但是呃，我真的很興奮。

Did you see his eyes?

你看到牠的眼睛了嗎？

Like the little feathery things around his eyes?

像牠眼睛周圍那些毛茸茸的小東西？

I've never noticed that.

我以前從沒注意過。

Anyway, he's getting tired.

總之，牠累了。

We got to let him go. 文法

我們得放牠走了。

All right,

好了，

here we go. 語氣意圖

準備好了。

Releasing the bird.

放鳥。

3 2 1.

3 2 1。

That was fast.

好快。

All right, let's look at it.

好了，我們來看看。

I mean, we probably just got the launch,

我想，我們可能只拍到了起飛，

but I like birds.

但我喜歡鳥。

All right,

好了，

I set out to make a cute little video of a bird hopping out of my hand, 片語動詞

我本打算拍一段可愛的小鳥從我手裡跳出去的影片，

but I actually learned a ton from this footage. 慣用語

但我實際上從這段畫面裡學到了很多。

Number one,

第一，

it's clear that the bird hops out of my hand,

很明顯，鳥是從我手裡跳出去的，

and I've never thought about that.

我以前從沒想過這一點。

I'm sure that's just common knowledge to ornithologists 片語搭配

我相信這對鳥類學家來說只是常識，

but for some reason I always thought birds just start flapping to fly. 片語搭配

但不知為何，我一直以為鳥只是開始拍打翅膀就能飛。

And he's hopping.

而牠是在跳躍。

Why would they not use their legs to get further away from the ground

牠們為什麼不用腿讓自己離地面更遠一點，

so their wings don't hit the ground or my hand or whatever?

這樣牠們的翅膀就不會碰到地面、我的手或者其他東西呢？

That's just cool.

這太酷了。

I've never thought about that.

我以前從未想過。

Number two,

第二，

I think it's neat that he points his tail towards the ground on that hop.

我覺得很有趣的是，在牠跳躍時，牠把尾巴指向了地面。

And I've got to believe he's doing that to reduce the vertical component of drag 講解

我相信牠這樣做是為了減少垂直方向的阻力，

so that he can hop farther. 文法

這樣牠就能跳得更遠。

Another thing that happens is on the downstroke, 用詞

另一件事是，在翅膀向下拍打時，

you can see that his feathers are together,

你可以看到牠的羽毛是合攏的，

but his feathers delaminate to reduce drag on the backstroke. 用詞

但在向上揮動時，牠的羽毛會分開以減少阻力。

We've seen that in a Smarter Every Day episode in the past.

我們在過去的一期 Smarter Every Day 節目中看過這個。

It's fun to see it again here.

在這裡再次看到真的很有趣。

Number four,

第四，

it's cool to see him transition that tail from being pointed down.

看到牠把尾巴從朝下轉變為抬起，真的很酷。

He raises it,

牠把尾巴抬起來了，

so he's getting ready for horizontal flight.

所以牠在為水平飛行做準備。

So, that transition from vertical flight to horizontal flight, 片語搭配

所以，在從垂直飛行過渡到水平飛行的過程中，

he straightens his tail out to get it in the game. 慣用語

牠把尾巴伸直，讓尾巴發揮作用。

He's getting ready to make corrections in horizontal flight.

牠準備好在水平飛行中進行修正了。

I think it's really cool to make your own observations 片語搭配

我覺得自己做出觀察真的很酷，

because all this probably exists in a scientific paper somewhere,

因為所有這些可能早就寫在某篇科學論文裡了，

but it's fun to actually see it for yourself and try to understand. 片語搭配

但親眼看到並嘗試去理解真的很有趣。

I'm going to be looking for these things

我以後會留意這些事情的，

every time I see a bird take off from now on. 片語搭配

從今以後每次看到鳥起飛我都會注意。

All right,

好了，

that's enough for this bird.

關於這隻鳥就說到這裡。

你們想看我的花園嗎？

These are my sunflowers.

這些是我的向日葵。
