【题目】阅读填空（共1小题）

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（有毒的） 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(电) 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（破坏） everything．It poisons our rivers, ponds and lakes and oceans along with the life in them．It pollutes our soils and crops, harm trees, and can cause the death of 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 travelling a long distance, take a bus or train to save fuel．

As research shows, acid rain harms our environment．But people everywhere can take small steps now to help protect our environment and make our children change．
