Pratique du Shadowing: Carbon Dioxide – Oxygen Cycle - Apprendre l'anglais à l'oral avec la vidéo

Création de la leçon...
1
Every breath you take connects you to one of Earth's most important cycles, the carbon dioxide oxygen cycle.
2
It's like our planet has its own breathing system, and it's happening all around us, every single day.
3
Here's how it works.
4
Humans and all land animals breathe in oxygen and breathe out carbon dioxide into the air.
5
The same thing occurs for marine animals, like fish.
6
But this exchange of gases occurs in water.
7
But where does all that fresh oxygen come from?
8
And what happens to all the carbon dioxide we release?
9
The answer is photosynthesis, nature's amazing recycling system.
10
On land, plants are like oxygen factories.
11
Using the sunlight's energy, they take in the carbon dioxide that animals breathe out.
12
Combine it with water from the soil to create glucose, basically plant sugar that feeds them.
13
The incredible part?
14
As they make their food, they release oxygen as a bonus gift to the rest of us.
15
But here's what might surprise you.
16
Most of our oxygen doesn't actually come from forests or land plants.
17
It comes from the ocean.
18
Tiny plant-like organisms, called phytoplankton, float throughout our oceans by the billions.
19
They're so small, you need a microscope to see them.
20
But they're photosynthesis superstars.
21
These microscopic ocean plants work the same way as land plants,
22
using the energy of sunlight and taking in carbon dioxide and water from their surroundings,
23
to make food, and pumping out oxygen in the process.
24
And because there are so many of them covering our vast oceans, phytoplankton produce about half of all the oxygen on Earth.
25
This creates a perfect cycle.
26
Animals use oxygen and produce carbon dioxide.
27
Plants and phytoplankton use that carbon dioxide and produce oxygen.
28
It's been working this way for millions of years, keeping our atmosphere balanced and our air clean to breathe.
29
Thank you.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
