IV. READING COMPREHENSION

A. Read the passage carefully and choose the correct answer.

Air pollution happens when wastes are poured into the atmosphere and the air becomes

contaminated and unpleasant to breathe.

There are many causes that lead to air pollution.

The most serious cause is the development of industry. Smoke, chemicals, and wastes from

factories which consist of sulphur and nitrogen oxides are dangerous for our health. Burning coal

and oil release other gases that are harmful to human.

Vehicles, especially cars, help to make our material life more comfortable and convenient;

however, they also account for air pollution in the cities.

People all know that they are breathing polluted air but it is difficult for them to choose, fresh

air or comfortable material life.
