41. Listening and Speaking
1 Listen to the tape and decide which
statements Professor Keeling does
NOT agree with.
1. We should stop depending on fossil
fuels for our energy.
2. 90% of our energy comes from
fossil fuels.

42. 3. We can replace fossil fuels with
cleaner sources of energy.
4. Nuclear power is a good source
of energy.

43. 2 Listen to Part 1 again and tick the energy sources that are mentioned. Complete the notes on them.
Sources of energy
Notes
Fossil fuels
Produce carbon dioxide
cheap and concentrated form of energy

44. Energy from the sun Nuclear power Wind power clean
not practical: need huge areas of land to provide enough energy
clean
not very practical with present technology
does not produce carbon dioxide
dangerous

45. 3 Listen to Part 2 and the list three things we can do to save energy.
First we must try to find ways to use fossil fuels that does not put carbon dioxide into the air.
Second we must produce products that are economical with energy.
Third we must ask people to cut
down on the energy they use.

46. 4 Listen to part 2 again and fill in the blanks.
LI BIN: …What about ________? They don’t cut down on their use of ______.
factories
energy

47. KEELING: No, they don’t. However, that is a ________ we must work on as a _______ community. That means _________ and __________　countries will have to work together.
problem
global
developing
developed

48. LI BIN: But it’s not the __________
countries that put most of the
carbon _______ into the air.
The developed countries are
really the ones to ______.
developing
dioxide
blame

49. Listening text Note: The USA is the largest energy user
in the world and the largest producer of
the greenhouse gas carbon dioxide.
China comes second in both of these.

50. China has been going through huge economic development, and has had as much growth in one decade as the industrial world experienced in nearly a century. However, it has been at a high cost to the environment.

51. FOSSIL FUELS AND OTHER
FORMS OF ENERGY
(L = Li Bin K = Keeling)
Li Bin, a university student, is interviewing Professor Keeling on the local student radio station about the use of fossil fuels and other sources of energy.

52. Part 1
L: Professor Keeling, I’ve read that we
must stop using fossil fuels if we want
to reduce the amount of carbon
dioxide in the air.
K: Yes, that’s right, Li Bin. However
it’s difficult.

53. Our modern industrial societies depend
on the energy we get from fossil fuels.
It’s a very cheap and concentrated form
of energy.
L: Is it true that about 90% of
the world's energy comes from fossil
fuels?
K: Yes, that's correct. And there
is enough to last for centuries.

54. L: Could we replace fossil fuels with
clear sources of energy like sun or
wind power?
K: I'm afraid not. We just can’t produce
enough. You need huge areas of land to
produce enough wind energy. The
technology we have at present cannot
provide enough sun energy.

55. L: So what about nuclear power?
That doesn’t produce carbon dioxide.
K: True, but it’s very dangerous.
Remember the accident at Chernobyl.
People are still dying of the radiation
that was produced by THAT disaster!

56. Part 2
L: So what CAN we do?
K: Well, there are three things. First we
must find ways of using fossil fuels that
won’t put carbon dioxide into the air.
Second, we must produce products that
are economical with energy. Third, we
must ask people to cut down on the
energy they use.

57. L: But that’s on a personal level. What
about factories? They don’t cut down cut
down their use of energy.
K: No, they don’t. However, that is a
problem we must work on as a global
community. That means developed and
developing countries will have to work
together.

58. L: But it’s not the developing countries
that put most of the carbon dioxide into
the air. The developed countries are
really the ones to blame.
K: That’s true. So we must work
together because global warming will
affect everyone. If we want the future
generations to have a good life, we must
ALL look after the planet.

59. Discussion DISAGREEMENT AGREEMENT I’m afraid I disagree with you.
I’m afraid not.
No, I don’t agree.
I don’t think so.
No way.
I doubt ....
AGREEMENT
Exactly.
That’s true. You’re right. That’s right. That’s correct.
I agree.

60. Professor Keeling: Whatever we do,
we have to do it as a global community.
That means developed and developing
countries will have to work together.
Li Bin: But it’s not the developing
countries who put most of the carbon
dioxide into the air. The developed
countries are really the ones to blame.

61. Sample Dialogue
S1: I agree with Li Bin. It is the
developed countries that are really
the ones to blame and to pay for that.
S2: Well, I don’t think so. I think
Professor Keeling is right. Whatever
we do, we have to do it as a global
community. Developed and developing
countries should work together to
improve the environment.

62. S3: I hold the same viewpoint as Li
Bin. In developed countries people are
producing a large amount of carbon
dioxide, which contributes to global
warming. Isn’t it their duty to do
something to decrease the speed of
global warming?
S1: Exactly.

63. S2: It is true that the developed countries
are the ones to blame and they should
do something. But is it right for
developing countries to look on without
doing anything? Remember we have
only one earth, which is like a big family.
All of us are family members. Think
about this: in a family, if one child
makes a mistake,

64. what should his brothers or sisters do—
blame him without doing anything or
help him correct the mistake?
S1: I see. We should take part in the
action instead of looking on and
complaining.
S3: I agree, too. Thank you. I’ve got a
better understanding about this.

65. Homework
Write short passage to give some advice on how we can do to solve the problem of global warming.

66. Help me, help you, help everyone.
Return GREEN to the earth!
Help me, help you, help everyone.
Return GREEN to
the earth!

74. hydropower
