2
The Quetzalcoatlus – one of the largest pterosaurs that ever lived – was able to… fly?!
3
That doesn’t sound right.
4
I mean, look at this thing – it’s the size of a giraffe!
5
However, giant pterosaurs’ ability to fly is really well-established in the scientific community.
6
So how on Earth did this giant manage to fly?
7
Hi, I’m Ever and this is MinuteEarth.
8
Thanks to the fossil record, we know that pterosaurs had wings with elongated hand bones, just like every other flying vertebrate. But simply having wings doesn’t mean you can actually fly.
9
If you’re too heavy for the size of those wings – or if you can't flap them fast enough – you’ll never get anywhere. And compared to the biggest flying creatures alive today – the Kori bustard, or the wandering albatross, or even the Andean condor, depending on how you measure it – the Quetzalcoatlus was way, WAY bigger.
10
But, despite this giant pterosaur’s wingspan, scientists estimate that it was only about as heavy as a large pig.
11
Now with the wing-to-mass ratio looking more decent, giant pterosaurs still needed to be strong enough to flap them.
12
And while wing muscles themselves aren’t preserved in the fossil record, we know pterosaurs had huge bumps in their forelimb bones and highly modified breastbones, with ample attachment space for powerful chest muscles – just like modern flying birds do.
13
So it’s reasonable to believe their wing muscles were pretty brawny.
14
On top of that, pterosaurs had mostly hollow bones that increased the volume of their respiratory system – again, just like modern flying birds – which allowed them to deliver tons of oxygen to all those flight muscles!
15
All this likely helped a Quetzalcoatlus’s big body stay aloft once it was in the air.
16
But getting into the air in the first place is the hardest and most energy-intensive part of flight.
17
Flying birds use their strong leg muscles to launch themselves into the air; that’s why the bigger a bird is, the larger and more powerful its legs tend to be.
18
Giant pterosaurs were so huge that, in order to jump into the air like birds, they would have needed truly gigantic legs that would have made them definitely too heavy to fly.
19
So they solved the whole launching problem in a different way: they used their powerful wings for the dual purpose of taking off and flapping.
20
And this strategy is so efficient, that bats independently evolved it as well.
21
By the way, I think that this is my favorite fact about giant pterosaurs –and bats, of course.
22
Once you look at all the evidence and the facts, it makes perfect sense that these giant pterosaurs could truly soar.
23
They might look too big and wonky, but the Quetzalcoatlus was about as close as we’ve ever come to a flying pig.
24
Pigs these days, of course, rarely fly.
25
And – sorry to be a downer, especially after that uplifting video - but in a lot of places, the conditions they’re kept in are heartbreaking.
26
As someone who loves animals, I hate to see any animal suffering so much.
27
That’s why we want to help make a genuine positive change with today’s sponsor, FarmKind.
28
FarmKind helps improve the lives of animals by recommending expert-reviewed, top charities whose work really makes a big difference.
29
Like Sinergia Animal, which is helping end the inhumane practice of keeping breeding pigs confined in tiny crates.
30
FarmKind never takes a cut of your donation; it all goes to the charities helping animals.
31
If you sign up for just $15 bucks a month, that’s just 50 cents a day, you'll save 350 animals from unnecessary suffering in your first year. Use the code MinuteEarth for a 50% boost on monthly donations.
32
If even a fraction of this community did that, we'd transform the lives of hundreds of thousands of animals. Check out the description for more info. Thanks FarmKind.

你能学到什么
通过这段视频，你可以锻炼英语口语练习中的两个关键技能：一是如何清晰表达复杂科学概念（如描述古生物飞行机制），二是自然融入赞助信息的口语逻辑。同时，视频中主持人的讲解节奏适中，非常适合用来练习“shadowspeak”技巧，提升听力理解与口语输出的同步性。
注意这些发音现象
视频里有不少连读和弱读需要关注：比如“doesn’t sound right”中“doesn’t”的尾音/t/弱化为喉塞音；“wing-to-mass ratio”中“wing-to”连读为/wɪŋtuː/；“all this likely helped”中“all this”连读为/ɔːlðɪs/。这些连读技巧能让你的口语更接近母语者水平，也是“看YouTube学英语”时需要重点模仿的部分。
像母语者一样表达
模仿主持人的节奏和重音是提升口语的关键。比如“the Quetzalcoatlus was about as close as we’ve ever come to a flying pig”一句，重音应放在“Quetzalcoatlus”“close”“flying pig”上，通过轻重对比突出核心信息。此外，主持人在解释科学原理时，会用“However”“But”“So”等连接词来调整节奏，这些词后的短暂停顿的也需要注意。利用“shadowing site”提供的逐句跟读功能，反复练习这些细节，能有效提升口语的流畅度和自然度。
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 |
|---|---|
| 被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的 | is brought · aren't preserved |
| 定语从句 who / which + 从句 — 补充说明人或事物 | someone who loves · Animal, which is |
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。
