Unit 5 Global Warming Page 52 Getting Started A Presentation About Global Warming Activity 1 Listen and Read
2
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.

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...

Na.

Is that a coal-burning stove?

76

77

78

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.

I'll tell my dad.

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。
