00:00:00,190 –> 00:00:20,160
Hello. I’m Margot Politis. Welcome to Study
English, IELTS preparation.

2
00:00:20,160 –> 00:00:25,380
Today we’re going to look at a topic you’ve
probably heard a lot about – global warming

3
00:00:25,380 –> 00:00:26,450
and the environment.

4
00:00:26,450 –> 00:00:33,890
First we’re going to look at ways of brainstorming,
taking notes and developing ideas.

5
00:00:33,890 –> 00:00:38,649
Watch while we play some vision that contains
ideas about the causes and effects of global

6
00:00:38,649 –> 00:00:40,010
warming.

7
00:00:40,010 –> 00:00:49,309
While you watch, try to note down some of
your ideas about what global warming is.

8
00:00:49,309 –> 00:01:08,820
OK so you saw some ideas, and perhaps took
some notes, during that clip. What were some

9
00:01:08,820 –> 00:01:11,480
of the ideas you saw?

10
00:01:11,480 –> 00:01:31,670
What has caused global warming?

11
00:01:31,670 –> 00:01:41,020
We saw gases in the air, cars, factory waste,
and people cutting trees down.

12
00:01:41,020 –> 00:01:45,630
So if you made those notes, you’d get an idea
that these were the things causing global

13
00:01:45,630 –> 00:01:47,530
warming.

14
00:01:47,530 –> 00:01:50,830
Now let’s listen to someone talk about the
causes.

15
00:01:50,830 –> 00:01:54,860
Heat-trapping gases are building up in the
atmosphere.

16
00:01:54,860 –> 00:02:01,810
Heat-trapping gases are building up in the
atmosphere. What else?

17
00:02:01,810 –> 00:02:07,310
So what is global warming? It’s the result
of billions of decisions. It’s caused by decisions

18
00:02:07,310 –> 00:02:12,170
made by individuals – like driving big cars
rather than small cars. And it’s caused by

19
00:02:12,170 –> 00:02:16,980
decisions made by corporations and nations,
like dumping waste into the atmosphere.

20
00:02:16,980 –> 00:02:22,870
Global warming is caused by about people using
big cars, and people dumping waste into the

21
00:02:22,870 –> 00:02:23,870
atmosphere.

22
00:02:23,870 –> 00:02:30,090
OK, so you’ve looked at the vision, and listened
to the speaker, and you’ve made notes about

23
00:02:30,090 –> 00:02:33,370
some of the causes of global warming.

24
00:02:33,370 –> 00:02:35,370
Now let’s look for some of the effects.

25
00:02:35,370 –> 00:02:52,319
So after watching that, you might be thinking
that global warming is having an effect on

26
00:02:52,319 –> 00:02:55,610
weather patterns, and on nature.

27
00:02:55,610 –> 00:02:57,130
Listen to the speaker.

28
00:02:57,130 –> 00:03:01,430
Nature is already responding to global warming.
There have been changes in global weather

29
00:03:01,430 –> 00:03:02,430
patterns.

30
00:03:02,430 –> 00:03:07,040
Trees are flowering earlier. Birds are laying
eggs earlier. Butterflies are moving up hills.

31
00:03:07,040 –> 00:03:16,740
So there’s been weather changes, and changes
to the ways trees, birds and butterflies behave.

32
00:03:16,740 –> 00:03:24,610
So we have a list of causes, and list of effects.
You might have identified those things from

33
00:03:24,610 –> 00:03:31,880
a text you’ve read, or from listening to someone
speak. This is how you can take notes.

34
00:03:31,880 –> 00:03:38,770
Once you’ve got your notes, you need to be
able to link those causes and effects in sentences.

35
00:03:38,770 –> 00:03:41,050
Let’s look at a couple of different ways.

36
00:03:41,050 –> 00:03:47,810
The first and most basic way is just making
a sequence of statements. This can sometimes

37
00:03:47,810 –> 00:03:53,610
be a powerful way of making a connection between
things. Listen.

38
00:03:53,610 –> 00:03:58,200
Heat-trapping gases are building up in the
atmosphere. Trees are flowering earlier. Birds

39
00:03:58,200 –> 00:04:02,520
are laying eggs earlier, and butterflies are
moving up hills.

40
00:04:02,520 –> 00:04:08,379
From the sequence of information, we realise
that birds are laying their eggs earlier because

41
00:04:08,379 –> 00:04:14,379
gases are making the earth warmer.
So a simple list of statements can show a

42
00:04:14,379 –> 00:04:17,560
cause and effect relationship.

43
00:04:17,560 –> 00:04:20,190
But there are other ways too.

44
00:04:20,190 –> 00:04:24,020
You can use the language of cause and effect.
We can say:

45
00:04:24,020 –> 00:04:28,070
X causes Y.

46
00:04:28,070 –> 00:04:31,840
Driving cars causes air pollution.

47
00:04:31,840 –> 00:04:34,720
There are many other word choices as well.

48
00:04:34,720 –> 00:04:38,500
Driving cars leads to air pollution.

49
00:04:38,500 –> 00:04:42,800
Driving cars results in air pollution.

50
00:04:42,800 –> 00:04:46,840
Notice you can also turn the sentence around.

51
00:04:46,840 –> 00:04:51,300
Air pollution is caused by driving cars.

52
00:04:51,300 –> 00:04:55,780
Air pollution is the result of driving cars.

53
00:04:55,780 –> 00:04:58,590
Air pollution is due to driving cars.

54
00:04:58,590 –> 00:05:02,280
Listen to an example here.

55
00:05:02,280 –> 00:05:04,660
There have been changes in global weather
patterns.

56
00:05:04,660 –> 00:05:10,440
Trees are flowering earlier. Birds are laying
eggs earlier. Butterflies are moving up hills.

57
00:05:10,440 –> 00:05:15,840
So what is global warming? It is the result
of billions of individual decisions.

58
00:05:15,840 –> 00:05:18,870
He’s talking about global warming.

59
00:05:18,870 –> 00:05:23,620
Global warming is the result of billions of
decisions.

60
00:05:23,620 –> 00:05:29,870
Global warming is due to billions of decisions.

61
00:05:29,870 –> 00:05:35,470
And remember we can turn the sentence around,
and change the phrase:

62
00:05:35,470 –> 00:05:40,169
Billions of decisions cause global warming.

63
00:05:40,169 –> 00:05:45,220
Billions of decisions result in global warming.

64
00:05:45,220 –> 00:05:49,820
Billions of decisions lead to global warming.

65
00:05:49,820 –> 00:05:55,320
When you’re writing about causes and effects,
make sure you use a variety of these kinds

66
00:05:55,320 –> 00:06:00,640
of phrases. There are many to choose from.
You should make lists of cause and effect

67
00:06:00,640 –> 00:06:07,889
language, and the kinds of vocabulary you
can use to describe cause and effect relationships.

68
00:06:07,889 –> 00:06:09,940
Now listen to another clip.

69
00:06:09,940 –> 00:06:15,729
Trees are flowering earlier. Birds are laying
eggs earlier. Butterflies are moving up hills.

70
00:06:15,729 –> 00:06:20,490
So what is global warming? It is the result
of billions of individual decisions.

71
00:06:20,490 –> 00:06:25,500
When you’re writing up your notes using cause
and effect language, you’ll need to be able

72
00:06:25,500 –> 00:06:29,090
to follow or track the subject of the text.

73
00:06:29,090 –> 00:06:31,060
Let’s look at that now.

74
00:06:31,060 –> 00:06:36,780
What is global warming? It is the result of
billions of individual decisions.

75
00:06:36,780 –> 00:06:43,970
The word ‘it’ here is called a referent. We
use referents to identify and track subjects

76
00:06:43,970 –> 00:06:47,449
through a conversation or a piece of writing.

77
00:06:47,449 –> 00:06:51,130
If you repeat the subject too many times,
your work will sound boring.

78
00:06:51,130 –> 00:06:54,430
Listen to this:

79
00:06:54,430 –> 00:07:00,740
The woman came into the room. The woman sat
down. The woman drank her tea.

80
00:07:00,740 –> 00:07:05,539
Look at how we use referents:

81
00:07:05,539 –> 00:07:12,600
The woman came into the room. She sat down.
She drank her tea.

82
00:07:12,600 –> 00:07:17,430
When you are reading, you’ll need to be able
to understand referents, and follow the subject

83
00:07:17,430 –> 00:07:19,110
through the text.

84
00:07:19,110 –> 00:07:26,570
Other referents are: this, that, these, those.

85
00:07:26,570 –> 00:07:31,120
Here’s the clip again. Listen to the way the
referents are used.

86
00:07:31,120 –> 00:07:35,240
What is global warming? It is the result of
billions of individual decisions.

87
00:07:35,240 –> 00:07:39,840
The word it here refers to global warming.

88
00:07:39,840 –> 00:07:46,270
What is global warming? Global warming is
the result of billions of decisions.

89
00:07:46,270 –> 00:07:48,210
And here’s another referent:

90
00:07:48,210 –> 00:07:52,090
What is global warming? It is the result of
billions of individual decisions.

91
00:07:52,090 –> 00:07:55,169
You can’t manage that at the scale of the
individual.

92
00:07:55,169 –> 00:07:58,729
He says:
You can’t manage that at the scale of the

93
00:07:58,729 –> 00:08:00,270
individual.

94
00:08:00,270 –> 00:08:04,199
He means:
You can’t manage global warming at the scale

95
00:08:04,199 –> 00:08:06,580
of the individual.

96
00:08:06,580 –> 00:08:09,770
But notice how the subject changes here.

97
00:08:09,770 –> 00:08:13,370
What is global warming? It’s the result of
billions of individual decisions.

98
00:08:13,370 –> 00:08:17,350
You can’t manage that at the scale of the
individual.

99
00:08:17,350 –> 00:08:22,020
Managing the atmosphere has to take place
at a global level. That’s why it needs international

100
00:08:22,020 –> 00:08:23,020
agreements.

101
00:08:23,020 –> 00:08:26,639
Managing the atmosphere has to take place
at a global level.

102
00:08:26,639 –> 00:08:32,440
The subject of this sentence is ‘managing
the atmosphere’.

103
00:08:32,440 –> 00:08:37,010
That’s why it needs international agreement.

104
00:08:37,010 –> 00:08:43,570
So the ‘it’ here no longer refers to global
warming. Now ‘it’ is referring to ‘managing

105
00:08:43,570 –> 00:08:45,870
the atmosphere’.

106
00:08:45,870 –> 00:08:51,600
That’s why managing the atmosphere needs international
agreement.

107
00:08:51,600 –> 00:08:56,350
When reading and writing, you must be very
careful to notice when subjects change, and

108
00:08:56,350 –> 00:09:03,890
to be clear about which subject is being referred
to. This can be quite tricky sometime.

109
00:09:03,890 –> 00:09:08,360
Next time you see a paragraph, try to highlight
all the referents like:

110
00:09:08,360 –> 00:09:10,560
it
this

111
00:09:10,560 –> 00:09:12,080
that
these

112
00:09:12,080 –> 00:09:14,380
those
he

113
00:09:14,380 –> 00:09:17,100
she
they

114
00:09:17,100 –> 00:09:22,020
Then try to work out what subject they are
all referring back to.

115
00:09:22,020 –> 00:09:28,360
It’s a great exercise, and it will help your
reading, writing and speaking skills.

116
00:09:28,360 –> 00:09:34,270
And that’s all for today. Hope you keep enjoying
your English studies and Study English! I’ll

117
00:09:34,270 –> 00:00:00,000
see you next time.
