Pratique du Shadowing: What is Supply and Demand? Explained for Beginners - Apprendre l'anglais à l'oral avec la vidéo

1
Have you ever wondered why prices rise when we want something most?
2
You'll save up for a concert, but the tickets will sell out in seconds and cost a fortune.
3
Or you're planning a vacation and it costs less to travel in September than in July.
4
What's going on?
5
It's the invisible forces of supply and demand shaping everything you see.
6
Stick around and you'll never look at a price tag the same way again again.
7
Supply and demand are the forces that shape nearly every price you see.
8
Supply means how much of something is available.
9
Demand is how much people want it.
10
When demand goes up and supply stays the same, prices rise.
11
When supply increases and demand drops, prices fall.
12
We can see these forces at work wherever wherever we look in the world around us.
13
Take these two musical artists as an example.
14
Our first musical artist is an international star.
15
The demand for her concerts is legendary.
16
When tickets went on presale, 10 million people rushed to sign up, but only 1 million tickets were available.
17
Because demand for tickets is high and supply is limited, she can charge a lot of money for each ticket.
18
Our second musical artist is new to the scene.
19
He advertises his latest show at a local venue, but demand for tickets is low.
20
After a few weeks, there are still plenty of tickets left.
21
Because the supply of tickets is high, but the demand is low, he lowers the ticket price to encourage people to buy them.
22
Economists use graphs to show how supply and demand interact.
23
Let's see how it works.
24
The vertical axis, or Y axis, shows price.
25
In our example, how much a concert ticket costs.
26
The horizontal axis, or X axis, shows quantity.
27
How many tickets are sold.
28
Every point on this graph shows a combination of a price and a quantity.
29
Now let's add the demand curve and the supply curve.
30
A demand curve always slopes downward, like a slide.
31
Why?
32
Because when prices go up, demand goes down.
33
In our example, as prices of tickets go up, fewer fans can afford the tickets.
34
The demand naturally curves down as the price goes up.
35
As the prices go down, more fans want the tickets and can afford them, so demand goes up.
36
A supply curve slopes upward, like walking up a hill.
37
Why?
38
Because sellers want to make money.
39
The higher the price of a ticket, the more profitable the concert becomes, so the venue is willing to sell more tickets.
40
The line starts low on the left and climbs to the right to show the rising price of the good, in this case, a concert ticket.
41
When we put both lines on the graph, they cross at one point.
42
That point is called the equilibrium, the point where supply and demand meet.
43
In our example, it's the price fans are willing to pay
44
and the number of tickets the venue or musical artist is willing to sell.
45
If a concert becomes super popular and demand goes up, prices rise.
46
Fans are willing to pay a premium to see their favorite artist perform.
47
If fewer people want to go, demand decreases and prices fall as the venue lowers ticket prices to fill seats.
48
Economists use these graphs because they help us predict what will happen in the real world.
49
From concert tickets or sneakers to electronics and toys.
50
Once you understand supply and demand, you can understand almost any price you see.
51
So the next time you see something selling out fast or suddenly getting cheaper, you'll know exactly what's going on behind the scenes.
52
You're not just a shopper, you're thinking like an economist.
53

About This Lesson

In this lesson, you will practice English through the engaging concept of supply and demand. You will explore how these economic principles affect pricing and availability of goods and services. By focusing on real-world examples, such as concert tickets, you will improve your listening comprehension and gain vocabulary that will help you articulate your thoughts on this topic. Through this lesson, you will also enhance your English speaking practice by using the shadowing technique, which will assist you in mimicking the natural rhythm and tone of native speakers.

Key Vocabulary & Phrases

  • Supply - The amount of a good or service available for sale.
  • Demand - The desire of consumers to purchase a good or service.
  • Equilibrium - The point at which supply and demand meet; the balance of price and quantity.
  • Curve - A graphical representation showing the relationship between price and quantity for both supply and demand.
  • Price - The amount of money required to purchase something.
  • Concert Tickets - A specific example of goods influenced by supply and demand.
  • Sellers - Individuals or companies that offer goods or services for sale.

Practice Tips

To maximize your learning experience, try the following steps while using the shadowing technique with this video. Start by listening to short segments of the transcript. Pause after a few sentences to repeat what you've heard; this will aid your English speaking practice. Focus on imitating the speaker's intonation and rhythm—this mimicking can greatly enhance your pronunciation. Remember to adjust your speed; if the video seems too fast, slow it down to catch every detail and maintain clarity in your shadow speech. As you practice, use your newly learned vocabulary in sentences related to supply and demand, perhaps discussing items you desire or everyday goods. This approach will prepare you for the IELTS speaking practice and help you feel more confident while speaking on economic topics in English.

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.
