Every time we turn on the TV or take a ride in a car, we could be adding to a problem called acid rain(酸雨). In this article, we'll learn something important about acid rain.
The formation of acid rain
When people use fuels(燃料), such as coal and gasoline(汽油),poisonous gases are given off. When these gases come together with rain, acid rain forms. Many power stations burn fuels in order to create the electricity that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline. When rain meets these gases, harmful things called acids form. This is acid rain. 
The harm of acid rain
Acid rain destroys everything that it touches. It poisons our rivers, ponds and lakes and oceans along with the life in them. It pollutes our soils and crops, harms trees, and can even kill fish and plants. Acid rain also eats away at our buildings.
The prevention of acid rain
We need to reduce and even stop the pollution that gets into our air. Turn off lights, televisions and other electrical appliances(电器) if we are not using them. Walk and take a bike whenever possible. If we are traveling a long distance, take a bus or train to save fuels.
As research shows, acid rain harms our environment. But people everywhere can take small steps now to help our environment for future generations.
