1
What would happen if Earth actually was flat?
2
Would we fall off?
3
Would we spin into the edge?
4
It's even weirder than you think, because for a sphere, gravity pulls in the same direction from all points on the surface.
5
But for a disc-shaped Earth, gravity depends on where you're standing.
6
In the center, gravity pulls you down, but as you walk toward the edges, gravity pulls you down and sideways.
7
And the consequences of that, well, all the ocean water would be pulled toward the center, trees would grow diagonally to fight against gravity,
8
and it would be near impossible to reach the outer edges of the Earth
9
because this sideways gravity would make it feel like climbing a never-ending mountain.
10
And on top of that, our flattened Earth has no internal layers, and it's the movement of our molten liquid core that causes our magnetic field.
11
So without it, we're just getting cooked by cosmic radiation.
12
And depending on our orientation, there would be only day or only night.
13
And lunar eclipses look like this.
14
So if Earth was flat, we'd be cooking on a space pan with no 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。
