Good morning, class.
3
Today's lesson will start with Mai and Nam's talk about some of the causes and consequences of global warming.
4
Would you like to go first, Mai?
5
Yes, thank you.
6
First, let me remind you what global warming refers to.
7
It's the increase in the Earth's temperature because of certain gases in the atmosphere.
8
Exactly.
9
These gases are mainly produced through human activities.
10
For example, burnt for energy, fossil fuels release large amounts of carbon dioxide into the atmosphere.
11
But how do these gases make the Earth warmer?
12
Well, they act like the glass in a greenhouse.
13
Trapping too much of the sun's heat, they stop it from escaping back into space.
14
This makes the planet hotter and hotter.
15
That's right!
16
That's why these heat-trapping pollutants are known as greenhouse gases, and their impact is called the greenhouse effect.
17
Global warming is also linked to rising sea levels.
18
As temperatures rise, polar ice caps melt faster, adding more water to oceans.
19
Higher sea levels can also lead to floods.
20
Each year, the consequences of global warming become more serious, and its negative impact on the environment and people get stronger.
21
Good job.
22
Thank you for sharing the information.

you.

Activity 2.
52
Listen to a talk and choose the main idea.
53
Hi everyone.
54
Thanks for offering me the opportunity to talk about black carbon.
55
Black carbon, also known as sood, consists of tiny pieces of black dust.
56
It mainly comes from forest fires and the burning of fossil fuels and crop waste.
57
We now know that it plays a much bigger role in global warming than previously thought.
58
Let me first talk more about the burning of crop waste.
59
Do you know why farmers do that?
60
Well, they believe that burning is the best way to clear land and prepare it for new crops.
61
However, these huge fires are the world's biggest source of soot.
62
In addition, burning crop waste is bad for the soil because it kills the useful organisms living in it.
63
But how long does black carbon stay in the atmosphere?
64
Actually, it only lasts for a few days or weeks after it is released.
65
However, its effect on the Earth's temperature is more powerful than that of carbon dioxide.
66
Black carbon traps more sunlight and sends it back into the air as heat.
67
In addition, when black carbon falls onto ice or snow, it warms the surface and increases the speed of melting.
68
So what do you think we should do to...
69
www.globalwarming.com Hi,
70
Na.
71
Is that a coal-burning stove?
72
Hi.
73
Yes, my dad bought it last week.
74
It heats up our home very quickly.
75
Let me put in some more coal.
76
Watch out!
77
You're too close and will burn yourself.
78
Don't worry, I'm very careful.
79
Yes, it feels very warm, but I must warn you, burning coal produces soot.
80
Oh no, I didn't know that.
81
Thanks so much.
82
I'll tell my dad.

Looking Back Pronunciation Listen and underline the stressed words, then practice saying the sentences with a natural rhythm.
86
1. Forests are helpful in cooling down our planet.
87
2. Plants can store a lot of carbon in their roots, branches and leaves.
88
3. Oceans can also remove carbon from the atmosphere and store it.
89
4. Oceans may start releasing the carbon they store as global temperatures rise.

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.
