Shadowing Practice: What If The World Lost OXYGEN for 5 seconds? | Dr Binocs Show | Peekaboo Kidz - Learn English Speaking with Video

1
Oh, little kitty don't forget to put on the oxygen tank.
2
O2 is so overrated.
3
Absolutely not kitty.
4
Hey friends, oxygen may not be the most abundant gas in the atmosphere, but it is undoubtedly Finally, the most important one.
5
Yes, so important that we can't handle its absence even for 5 seconds.
6
So in today's episode, let me take you through the world without O2 and answer a world shattering question.
7
What if the Earth lost oxygen for just 5 seconds?
8
Zoom in.
9
Now as we know, holding our breath for merely 5 seconds doesn't seem to be a big deal
10
and some of us can even hold it up to a minute.
11
But it is not the same case with everything else.
12
Forget about a minute, in just 5 seconds, without oxygen, the world would look entirely different.
13
How?
14
Let us see, or shall I say, we won't be able to see that clearly,
15
as the absence of O2 will turn the bright sky into dark and gloomy.
16
Yes, that's because sunlight reaches the Earth's surface due to multiple reflections
17
that occur when light particles bounce off the particles in the air,
18
like dust, molecules, etc. So, without the oxygen in our environment,
19
there will be fewer particles for the light to bounce on.
20
So the sky would appear as dark as night.
21
And it's not only the sky above us, but the earth's surface below us too will also get affected by the lack of O2.
22
Yes, as oxygen constitutes 45% of the Earth's crust,
23
without it, the Earth below us would disappear and we would re-fall down into the ground.
24
And in case you were busy chilling on the beach, be prepared to get burnt skin.
25
Yes, that's because the ozone layer that protects us from the harmful UV radiation is entirely composed of oxygen.
26
So basically, without this O2 shield, the Earth will turn into an oven.
27
But what if you decide to run into the water to save your skin for a while?
28
Well, as we know, water consists of two parts of hydrogen, one part of oxygen.
29
So without the 33% oxygen, water would be free hydrogen gas.
30
Hydrogen gas, being the lightest of all the elements, will fly to the upper troposphere and gradually vanish into the vastness of space.
31
So probably, the Earth could be a massive planet of only deserts in almost no time at all without our precious oxygen.
32
At the same time, losing oxygen will eventually result in losing 21% of air pressure.
33
This would cause our eardrums to explode due to a condition called parotrauma.
34
It is an injury sustained from failure to equalize the pressure of an air containing space with that of the surrounding environment.
35
In short, we will suffer from hearing loss.
36
As oxygen is a critical binder in concrete structures, without it, the compounds do not hold their rigidity.
37
So our eyes will witness the slow
38
and cruel crumbling of our world as all the buildings
39
and monuments will begin to collapse even vehicles operating on any
40
type of fuel relying on internal combustion engines would stop since there isn't any oxygen
41
for the combustion process and we would see aircrafts and helicopters falling from the sky for the same reason.
42
Phew!
43
So, we should be thankful to Mother Nature for the gift of oxygen.
44
Trivia time!
45
Did you know the oxygen we breathe to live roughly makes up 21% of our atmosphere?
46
Yes, and nearly 78% is nitrogen and 1% consists of carbon dioxide and other gases.
47
Hope you learned something new in today's episode.
48
Until next time, it's me Dr. Binox zooming out!
49
Ah, never mind!
50
Thank you.

Practice Tips

To effectively use this lesson for shadowing and improving your English pronunciation, follow these tips:

  • Start with Listening: Play the video a few times to familiarize yourself with the tone and pace. Understanding the context can greatly improve your shadowing experience.
  • Record Yourself: After practicing shadowing, record your voice. This will help you identify areas where you need improvement.
  • Focus on Intonation: Pay attention to the speaker’s pitch and rhythm. The dynamic nature of the transcript allows you to work on expressing emotions similar to how the speaker delivers their message.
  • Break It Down: Don’t hesitate to separate complex sentences into smaller phrases when shadowing. This will ease the process of matching your pronunciation with the speaker.
  • Use a Shadowing App: Consider utilizing a shadowing app that allows you to practice with different speeds, helping you adapt to various speaking paces.

By following these steps and incorporating the new vocabulary, you can significantly improve your English speaking skills, sound more fluent, and boost your confidence in communicating complex topics like environmental science. With consistent practice on your shadowing site or app, your pronunciation will see remarkable improvement over time.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
