1
This is Earth.
2
This is where you live.
3
And this is where you live in your neighborhood.
4
The solar system.
5
Here's the distance between the Earth and the Moon.
6
Doesn't look too far, does it?
7
Think again.
8
At their farthest point, the Earth and the Moon are 252,088 miles away.
9
Inside that distance, you can fit every planet in our entire solar system.
10
But let's talk about planets.
11
The great red spot on Jupiter, that's about two times as big as Earth.
12
And Saturn is about nine times wider than Earth.
13
Saturn's rings are so large that a few of the fragments within them are as large as mountains.
14
But that's nothing compared to our sun.
15
Just remember, this is Earth.
16
And this is Earth from the Moon.
17
This is Earth from Mars.
18
Here's Earth from just behind Saturn's rings.
19
And here's Earth from just beyond Neptune, four billion miles away.
20
But a billion's a big number, so let's put that in perspective.
21
One million seconds equals about 11 and a half days, whereas one billion seconds equals over 31 years.
22
Let's step back a bit.
23
Here's the size of Earth compared with the size of our sun.
24
Terrifying, right?
25
And here's that exact same sun from the surface of Mars.
26
As Carl Sagan once mused, The total number of stars in the universe is larger than
27
all the grains of sand on all the beaches of the planet Earth.
28
And there are some stars out there that are much, much bigger than our little wimpy sun.
29
The biggest star we know of, V.Y.
30
Canis Majoris, is about 2,000 times the diameter of our sun.
31
But none of those compares to the size of a galaxy.
32
In fact, if you shrink the size of our solar system down to the size of a quarter, and shrink the Milky Way galaxy down using the same scale,
33
the diameter of the Milky Way will be roughly the size of the United States.
34
That's because the Milky Way galaxy is huge.
35
Its diameter is about 100,000 light years wide, which, when converted to miles, is about 621 quadrillion, 371 trillion,
36
192 billion, 237 million, 333,890 miles.
37
Inside of all of that is you.
38
You live in this tiny, tiny portion of the Milky Way.
39
But even still, our galaxy is a little runt compared with some others.
40
NGC 6744, a spiral galaxy similar to our own, is twice as wide as the Milky Way,
41
stretching over 200,000 light years across.
42
It is massive. But let's think bigger.
43
In this picture alone, taken by the Hubble telescope, there are thousands and thousands of galaxies,
44
each containing millions or billions of stars with their own planets.
45
Some of the objects seen here may have formed as many as 11 billion years ago, just 3 billion years after the Big Bang.
46
This period of time is considered one of the busiest star-forming periods.
47
And just keep this in mind, that's a picture of a very small, small part of the universe.
48
So if you're ever feeling upset about your favorite show being cancelled, or the fact that they play Christmas music way too early, just remember, this is your home.
49
Earth.

有趣的宇宙视角：一段引发思考的视频场景
想象一下，你正在观看一段关于宇宙的科普视频，画面从地球逐渐拉远，展示月球、太阳系、银河系乃至更遥远的星系。视频用生动的对比和数据，让你瞬间感受到人类在宇宙中的渺小。这样的场景不仅能开阔视野，也是练习英语口语的好素材——语速适中、用词生动，非常适合用来做“英语影子跟读”练习。
实用表达与搭配，轻松积累词汇
- put...in perspective：换个角度看。比如视频中用“把十亿秒换算成31年”来解释大数，就可以说“put a billion in perspective”。
- step back：退一步想。当视频从地球尺寸转向太阳时，用到“step back a bit”，很自然的过渡表达。
- compared with：与……相比。描述星系大小时，“our galaxy is a little runt compared with some others”这样的句子很实用。
- muse：沉思、思索。卡尔·萨根“mused”关于恒星数量的名言，这个词比“think”更有文学感。
- fit...inside：容纳。“地球和月球的距离能fit下所有行星”，简单又形象。
现在就来挑战影子跟读，提升英语口语！
想要练好“英语口语练习”，不妨试试这个“英语影子跟读”任务：找到视频中“从地球到 Neptune 这段描述”（大约从“Here's Earth from just behind Saturn's rings”开始），先听3遍，注意语音语调；然后跟着录音逐句跟读，尽量模仿语速和重音；最后不看字幕，直接跟读，看看能否跟上节奏。这个方法能有效提高英语发音和流畅度，坚持一周，你会发现自己的口语进步明显！
看视频学英语就是这么有趣，既能了解宇宙奥秘，又能提升英语能力。快打开视频，开始你的“shadowspeaks”之旅吧！
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
