TASK 2. Work in pairs, talk with your
friend about the advantages and
disadvantages of using each source of energy
Example:

A: I think that wind power can be an alternative sources
(1) source of energy
of energy.
B: Why do you think so?
A: Because our major sources of energy are running out
while the wind is abundant and unlimited.
(2) advantage
B: I know it is also clean and safe to the environment.
(3) advantage
However, it is not available when there is no wind.
(4) disadvantage


Task 2: Talk with your friend about the

2. Task 2: Talk with your friend about the
advantages and disadvantages of using
each alternative source of energy
1. newclear power / unlimited./ dangerous.

A: I think/believe that nuclear
power can be an alternative
source of energy.
B: Why do you think/ believe so?
A: Because our major sources of
energy are running out while the
nuclear power is unlimitted.
B: I know. However, it can be
dangerous.


Task 2: Talk with your friend about the
advantages and disadvantages of using
each alternative source of energy

wind power / abundant and unlimited / clean and safe to

the environment / not available when there is no wind.

A: I think/believe that ....................
wind power
can be an alternative
sources of
energy.
B: Why do you think/ believe so?
A: Because our major sources of
energy are running outabundant
while and

B: I know it is also clean and safe to


Task 3: Work in groups. Make a conversation to express your
belief on the increasing use of alternative sources in the future,
using the idiea from Task 2.
Student A: Give your suggestion of an alternative source of
energy. (I think/believe that more and more people will use… as a
source of energy in the future.)

Student B: Ask A for the reason. (Why do you think/believe so?)
Student A: Explain the reason. (Because it is unlimited…… .)
Student C: Say the disadvantage of that source. (But it is
expensive and only available during…. .)

Student D: Express his own opinion. (I hope the progress of
science and technology will help overcome this problem…. .)

Task 3: Work in groups. Make a conversation to express your

belief on the increasing use of alternative sources in the future,
using the idiea from Task 2.
More and more people / use solar power/ a
source of energy/ in the future
Why/ think so?
because/ available, unlimited & easy to use
But it is expensive and we can only have it
when there is the sun./ …….

I hope that scientists will help overcome…
