Hello. I'm Margot Politis. Welcome to Study English, IELTS preparation.
0:20
Today we're going to look at a topic you've probably heard a lot about - global warming
0:25
and the environment.
0:26
First we're going to look at ways of brainstorming, taking notes and developing ideas.
0:33
Watch while we play some vision that contains ideas about the causes and effects of global
0:38
warming.
0:40
While you watch, try to note down some of your ideas about what global warming is.
0:49
OK so you saw some ideas, and perhaps took some notes, during that clip. What were some
1:08
of the ideas you saw?
1:11
What has caused global warming?
1:31
We saw gases in the air, cars, factory waste, and people cutting trees down.
1:41
So if you made those notes, you'd get an idea that these were the things causing global
1:45
warming.
1:47
Now let's listen to someone talk about the causes.
1:50
Heat-trapping gases are building up in the atmosphere.
1:54
Heat-trapping gases are building up in the atmosphere. What else?
2:01
So what is global warming? It's the result of billions of decisions. It's caused by decisions
2:07
made by individuals - like driving big cars rather than small cars. And it's caused by
2:12
decisions made by corporations and nations, like dumping waste into the atmosphere.
2:16
Global warming is caused by about people using big cars, and people dumping waste into the
2:22
atmosphere.
2:23
OK, so you've looked at the vision, and listened to the speaker, and you've made notes about
2:30
some of the causes of global warming.
2:33
Now let's look for some of the effects.
2:35
So after watching that, you might be thinking that global warming is having an effect on
2:52
weather patterns, and on nature.
2:55
Listen to the speaker.
2:57
Nature is already responding to global warming. There have been changes in global weather
3:01
patterns.
3:02
Trees are flowering earlier. Birds are laying eggs earlier. Butterflies are moving up hills.
3:07
So there's been weather changes, and changes to the ways trees, birds and butterflies behave.
3:16
So we have a list of causes, and list of effects. You might have identified those things from
3:24
a text you've read, or from listening to someone speak. This is how you can take notes.
3:31
Once you've got your notes, you need to be able to link those causes and effects in sentences.
3:38
Let's look at a couple of different ways.
3:41
The first and most basic way is just making a sequence of statements. This can sometimes
3:47
be a powerful way of making a connection between things. Listen.
3:53
Heat-trapping gases are building up in the atmosphere. Trees are flowering earlier. Birds
3:58
are laying eggs earlier, and butterflies are moving up hills.
4:02
From the sequence of information, we realise that birds are laying their eggs earlier because
4:08
gases are making the earth warmer. So a simple list of statements can show a
4:14
cause and effect relationship.
4:17
But there are other ways too.
4:20
You can use the language of cause and effect. We can say:
4:24
X causes Y.
4:28
Driving cars causes air pollution.
4:31
There are many other word choices as well.
4:34
Driving cars leads to air pollution.
4:38
Driving cars results in air pollution.
4:42
Notice you can also turn the sentence around.
4:46
Air pollution is caused by driving cars.
4:51
Air pollution is the result of driving cars.
4:55
Air pollution is due to driving cars.
4:58
Listen to an example here.
5:02
There have been changes in global weather patterns.
5:04
Trees are flowering earlier. Birds are laying eggs earlier. Butterflies are moving up hills.
5:10
So what is global warming? It is the result of billions of individual decisions.
5:15
He's talking about global warming.
5:18
Global warming is the result of billions of decisions.
5:23
Global warming is due to billions of decisions.
5:29
And remember we can turn the sentence around, and change the phrase:
5:35
Billions of decisions cause global warming.
5:40
Billions of decisions result in global warming.
5:45
Billions of decisions lead to global warming.
5:49
When you're writing about causes and effects, make sure you use a variety of these kinds
5:55
of phrases. There are many to choose from. You should make lists of cause and effect
6:00
language, and the kinds of vocabulary you can use to describe cause and effect relationships.
6:07
Now listen to another clip.
6:09
Trees are flowering earlier. Birds are laying eggs earlier. Butterflies are moving up hills.
6:15
So what is global warming? It is the result of billions of individual decisions.
6:20
When you're writing up your notes using cause and effect language, you'll need to be able
6:25
to follow or track the subject of the text.
6:29
Let's look at that now.
6:31
What is global warming? It is the result of billions of individual decisions.
6:36
The word 'it' here is called a referent. We use referents to identify and track subjects
6:43
through a conversation or a piece of writing.
6:47
If you repeat the subject too many times, your work will sound boring.
6:51
Listen to this:
6:54
The woman came into the room. The woman sat down. The woman drank her tea.
7:00
Look at how we use referents:
7:05
The woman came into the room. She sat down. She drank her tea.
7:12
When you are reading, you'll need to be able to understand referents, and follow the subject
7:17
through the text.
7:19
Other referents are: this, that, these, those.
7:26
Here's the clip again. Listen to the way the referents are used.
7:31
What is global warming? It is the result of billions of individual decisions.
7:35
The word it here refers to global warming.
7:39
What is global warming? Global warming is the result of billions of decisions.
7:46
And here's another referent:
7:48
What is global warming? It is the result of billions of individual decisions.
7:52
You can't manage that at the scale of the individual.
7:55
He says: You can't manage that at the scale of the
7:58
individual.
8:00
He means: You can't manage global warming at the scale
8:04
of the individual.
8:06
But notice how the subject changes here.
8:09
What is global warming? It's the result of billions of individual decisions.
8:13
You can't manage that at the scale of the individual.
8:17
Managing the atmosphere has to take place at a global level. That's why it needs international
8:22
agreements.
8:22
Managing the atmosphere has to take place at a global level.
8:26
The subject of this sentence is 'managing the atmosphere'.
8:32
That's why it needs international agreement.
8:37
So the 'it' here no longer refers to global warming. Now 'it' is referring to 'managing
8:43
the atmosphere'.
8:45
That's why managing the atmosphere needs international agreement.
8:51
When reading and writing, you must be very careful to notice when subjects change, and
8:56
to be clear about which subject is being referred to. This can be quite tricky sometime.
9:03
Next time you see a paragraph, try to highlight all the referents like:
9:08
it this
9:10
that these
9:12
those he
9:14
she they
9:17
Then try to work out what subject they are all referring back to.
9:22
It's a great exercise, and it will help your reading, writing and speaking skills.
9:28
And that's all for today. Hope you keep enjoying your English studies and Study English! I'll
9:34
see you next time.
