1
You know how many people have actually been on the Moon?
2
Twelve. That's all.
3
But one day, we may go back there.
4
We have a lot more to learn about the Moon and space in general.
5
So some day, maybe in your lifetime, we'll send astronauts out there to study and explore.
6
Do you want to be one of them?
7
If you do, let me give you some helpful tips about a little thing called gravity, because you're going to need to know all about what gravity is and how it works if you're going to escape the pull of Earth and fly to the Moon.
8
Now, you already know that astronauts can leave the Earth, but it takes a lot of effort to boldly go where few have gone before.
9
But once astronauts reach the speed called escape velocity, they're able to overcome the force of Earth's gravity and get into orbit around our planet or head on over to the Moon.
10
So, this brings up an interesting question: what happens when an object gets away from Earth's gravity, but close to the moon's gravity?
11
You already know that gravity is the force that keeps us from flying off the surface of the Earth.
12
And you know that gravity pulls things, not down, but towards the Earth's center.
13
You also know that gravity exists between any objects that have mass, and the greater an object's mass is, the greater the effect of its gravity, or pull on other objects, is.
14
But there's something more.
15
Remember Isaac Newton, the apple tree guy?
16
He determined that the amount of gravitational force, or pull, between two objects also depends on how far apart they are.
17
So the farther away something is from the Earth, the less it will feel the pull of Earth's gravity.
18
And the closer it gets to the Moon, the more it will feel the Moon's gravity pulling on it.
19
Let's do a little pretending to see what happens to something when it moves closer to an object that has a really large mass, and therefore, a really strong pull of gravity.
20
If you've ever made a wish on a shooting star, you've seen the effect of Earth's gravity pulling on an object.
21
Shooting stars, which are actually meteors, occur when pieces of rock break off from a passing comet or asteroid and get too close to the Earth.
22
For example, say this globe represents the Earth, and the marble represents a piece of space rock that's flying by.
23
You can see that there's a huge difference in size between the two objects.
24
And, if we were to put them on a scale, we'd see that there's a big difference in their mass too.
25
Our model Earth has a larger mass.
26
If the space rock is far away from the Earth, then it can go on its merry way, since it won't be affected by the Earth's gravity.
27
But if it gets too close, then it and the Earth engage in a bit of tug-of-war, since both have gravity that pull on one another.
28
It's not much of a fight though.
29
The more massive Earth has a much larger gravitational pull, so the rock gets caught in Earth's gravity, and most of the time, it gives us a brilliant streak of light we call a meteor.
30
But what does this mean for our space travelers?
31
Well when an astronaut ship takes off for the Moon and moves away from the Earth, the farther away it goes, the less it feels the pull of Earth's gravity.
32
And, as it gets closer to the Moon, the spaceship begins to feel the tug of the Moon's gravity more.
33
So even though the Moon has a smaller mass than the Earth, and has less of a pull on the ship than the Earth does...
34
once the ship gets closer to the Moon than the Earth, the Moon's gravity pulls the ship toward it.
35
And then the astronauts can make a safe landing!
36
So we can make the argument that two things affect the pull of gravity: First, the size of the object.
37
Objects with a bigger mass have a stronger pull of gravity.
38
And second, the distance between objects.
39
The farther apart objects are, the weaker the pull of gravity between them, and the closer together they are, the stronger the pull of gravity.
40
All of this means that when the day comes that you're flying a spaceship to the Moon, you just have to escape Earth's gravity, and then get close enough to the Moon to enter its gravity.
41
Remember that when you're grown up, and you're welcome.
42
If you wanna thank me, you could just name a crater or something after me when you get there.

背景与上下文
在这段视频中，演讲者讨论了月球以及重力的基本概念。虽然只有12人到过月球，但未来可能会有更多的宇航员踏上这一伟大的旅程。演讲者鼓励观众思考自己是否希望成为未来的宇航员，并提供了一些关于重力的有用知识，帮助观众理解在太空旅行中如何克服地球的引力。一些精确的科学解释和示例，使得重力的相关概念既生动又易于理解。
日常交流的五个常用短语
- What happens when an object gets away from Earth's gravity?（当一个物体脱离地球的引力时会发生什么？）
- It takes a lot of effort to boldly go where few have gone before.（要勇敢地前往鲜有人踏足之地，需要付出很多努力。）
- The farther away something is from the Earth, the less it will feel the pull of Earth's gravity.（物体离地球越远，感觉到的地球引力就越小。）
- The more massive Earth has a much larger gravitational pull.（更大质量的地球具有更大的引力。）
- Once the ship gets closer to the Moon, the Moon's gravity pulls the ship toward it.（当飞船靠近月球时，月球的引力便拉着飞船向它靠近。）
逐步模仿指南
要有效地练习模仿这段视频内容，可以按照以下步骤操作：
- 了解内容：在开始模仿之前，先仔细观看视频，确保理解了重力以及月球相关的科学概念。
- 分段聆听：将视频分成小段，逐一倾听。每一小段后暂停，重复刚才听到的内容。这种方法适合用于 看YouTube学英语。
- 专注语音：注意演讲者的发音、语调和停顿。记录下重点短语并多次重复，使用 shadowspeak 技术进行练习，从而提高口语流利度。
- 进行模拟对话：尝试与朋友或家人进行角色扮演，模拟出一位宇航员和科学家之间的对话，使用视频中的短语和科学知识。
- 反复练习：每天安排特定时间，反复观看视频并练习，提升发音和理解能力，逐步走向流利的口语表达，许多考生在 雅思口语练习 中都采用这样的策略。
通过采取这些步骤，您将能够不断提升英语口语能力，进而自信地进行日常交流。
视频中的语法
说话人最常用的结构，并附上视频中的原话：
| 结构 | 视频中的用法 |
|---|---|
| 现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事 | have actually been · have gone · you've ever made |
| “will” 表将来 will + 动词 — 决定、承诺或预测 | we'll send · will feel · won't be |
| 义务：must / have to / need to 表示某事是必要的 | need to know · have to escape |
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。
