1
Let's evolve so you can fly.
让我们一起进化,好让你能够展翅高飞。
2
To get off the ground, you'll need a pair of wings with a wingspan of about 7 meters.
要起飞,你需要一对翼展约7米的翅膀。
3
But to actually flap those wings, you need stronger pectoral muscles and a keel bone to anchor them, or they'd rip off instantly.
但要真正扇动那些翅膀,你需要更发达的胸肌和一块用来固定胸肌的龙骨突,否则翅膀会立刻被扯掉。
4
Still, the rest of your bones are too bulky.
5
Bird bones are hollow, with air sacs connected directly to their lungs, so each downstroke pushes a fresh wave of oxygen directly through the system.
6
We'll make yours the same, so the faster you flap, the more efficiently you breathe.
7
Your next problem is Ephrin B3, a small molecule in your spinal cord that makes alternating limb movement,
8
aka walking, natural for you by separating the limb nerve circuits.
9
Birds lost this molecule and are now used to flapping both wings at the same time.
10
After getting rid of it, you just need fuel.
11
Flying takes more than twice the energy of running, so you'll need around four cheeseburgers worth of energy for every hour of flying.
12
So other activities like doom scrolling will have to be put on pause.
13
Biologically speaking, you're not a human anymore.
14
You're closer to an Argentavis, one of the largest birds to ever fly, with plane -sized wings.
15
If evolution got this beast airborne, maybe someday it could get us airborne too.

推荐视频

通过这个视频你能学到什么

这个关于“人类能否进化出飞行能力”的视频不仅能激发你的好奇心,还能提升英语口语技能。首先,它能帮助你练习雅思口语练习中常用的“解释复杂概念”的表达能力,比如如何用简单语言说明“龙骨突”“ Ephrin B3分子”等术语。其次,你可以学习如何在英语口语练习中自然融入假设性讨论,像视频里那样用“如果……会怎样”的结构展开想象。此外,通过模仿视频中的逻辑推进,还能提升口语表达的条理性。

注意这些语音现象

视频中的连读和弱读现象值得关注。比如“get off”会连读成/ɡet ɒf/,“need a”会弱读为/niːdə/,“a pair of”则可能连读为/ə peərəv/。还有“Bird bones are hollow”中的“are”会弱化为/ə/,让整个句子听起来更流畅。这些看视频学英语时容易忽略的细节,正是 native speaker 口语自然的关键。

像母语者一样表达

想要练好shadowspeak或shadow speak,可以模仿视频中的节奏和重音。比如“To get off the ground, you'll need a pair of wings with a wingspan of about 7 meters”这句话,重音落在“get off”“need”“wings”“wingspan”“7 meters”上,节奏先慢后快,突出关键信息。再比如“Flying takes more than twice the energy of running”,“more than twice”要重读,强调能量消耗之大。通过反复跟读,你会逐渐掌握这种轻重有致的表达技巧,让口语更地道。

视频中的语法

被动语态 be + 过去分词 — 强调发生了什么,而不是谁做的be put

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。
