possible in few minutes.

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… .)

Why/ think so?

But it is expensive and we can only have it

when there is the sun./ …….

because/ available, unlimited & easy to use

More and more people / use solar power/ a

source of energy/ in the future

I hope that scientists will help overcome…

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.

1 Practice speaking again As much

as possible.
