TASK 1. Read and tick the appropriate box A (for the advantages) or D (for the disadvantages)
A: I think that can be an alternative sources
of energy.
B: Why do you think so?
A: Because our major sources of energy are running out while

wind power
(1)
the wind is abundant and unlimited. (2)
it is also clean and safe to the environment.
(3)
it is not available when there is no wind.
(4)
However,
B: I know
Example:
