祈使句型

But believe it or not, this guy is actually 100% blind and he figured out a way to see the world with his ears.

但信不信由你，這個人其實是100%的盲人，他想出了一個用耳朵看世界的方法。

And how does someone see with their ears?

Hi, I'm Daniel and I don't need eyes to live in this world.

嗨，我是 Daniel，我不需要眼睛就能生活在這個世界上。

When Daniel was 13 months old, doctors had to remove his eyes completely and back then he was faced with a choice, spent the rest of his life blind or find another way to see.

在丹尼爾13個月大的時候，醫生不得不完全摘除他的眼睛，那時他面臨著一個選擇，眼盲度過他的餘生，還是找到另一種方式生活下去。

So he developed his vision with the help of his ears by using sound in a special way.

他在耳朵的幫助下，以特殊的方式用聲音來發展他的視覺。

Basically I just make tongue clicks and that creates echoes from surfaces and I use that information so that I can move around.

基本上我只是發出舌頭的彈動聲，這就產生了表面的回聲，我利用這些資訊就可以到處移動。

It's the same technique bats and submarines use and with enough practice, humans can master it too with only a few clicks.

蝙蝠和潛水艇也是使用相同的技術，只要有足夠的練習，人類只需彈擊幾下也可以掌握它。

Daniel can get a sense of what objects are around him, how far they are from him and even what some of them are made of.

Daniel 可以感覺到他周圍有哪些物體，它們離他有多遠，甚至有些物體是由什麼製成的。

And he can do it all even in the darkest night.

而且他能做到這一切，即使是在最黑暗的夜晚。

When people use light to see, they're basically using reflected light that bounces from surfaces back to their eyes.

當人們用光看東西時，他們基本上是用反射光，從物體表面反射到他們的眼睛。

I do a very similar thing but using sound instead of light.

我做了一件非常類似的事情，但用聲音而不是光。

So we have a structure here that has a roof: a pavilion.

所以我們這裡有一個有屋頂的結構：一個涼亭。

All you need to do is go in a dark room and make a sound with your mouth.

你所需要做的就是到一個黑暗的房間裡，用你的嘴發出聲音。

Now by coming closer to an object, you'll hear the sound slowly changing, telling you how far the object is and little by little you will be able to make a map in your head of where you are, just like a bat.

現在，靠近一個物體，你會聽到聲音慢慢變化，告訴你這個物體有多遠，一點一點地，你就能在腦海中繪製出你所在的地圖，就像一隻蝙蝠一樣。

You'll be able to hear that signal bounce from a surface, just like an echo locator is able to hear.

你能夠聽到該信號從表面反彈，就像回聲定位器一樣。

Thanks to his ears, Daniel can live a life of freedom.

Daniel 的耳朵讓他可以過上自由的生活。

He can hike, bike, cook, travel the world all on his own terms.

他可以按照自己的意願徒步旅行、騎自行車、做飯、環遊世界。

I have rarely needed anyone to do things for me.

I live my own life and I see no reason that other blind people should be restricted or limited.

我過著自己的生活，我認為盲人沒有理由被受限制或制約。

That's why Daniel decided to create a non-profit school where not only blind people, but also autistic children and sighted people can learn the techniques Daniel uses.

這就是為什麼 Daniel 決定創建一所非營利性學校，不僅盲人，連自閉症兒童和盲人也可以學習丹尼爾使用的技術。

I've been learning from Daniel since 2018 when I moved here, he has really helped my confidence with being able to go out and navigate my world.

我從2018年搬到這裡後就一直在向丹尼爾學習，他真的幫助了我的信心，讓我能夠走出去，探索我的世界。

Not because he can live without vision, but because he is a teacher who shares his knowledge with the people who need it the most.

不只是因為他可以在沒有視力的情況下生活，而是因為他是一位老師，他分享的知識給最需要的人。

You've helped children and other people in the world who can't see, navigate their world, helping their parents understand, thank you for giving back!

你幫助兒童和世界上其他看不見的人探索他們的世界，幫助他們的父母理解，謝謝你的回饋。

Nobody can really see what freedom is, but thanks to Daniel, maybe you'll be able to hear it.

沒有人能夠真正看到自由是什麼，但感謝 Daniel，也許你能夠聽到它。
