19．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 i（66）mportantabout 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 t（67）ogetherwith rain，acid rain forms．Many power stations burn fuels in order to c（68）reatethe 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，
h（69）armfulthings called acids form．This is acid rain．
The harm of acid rain
Acid rain destroys everything that it t（70）ouches．It poisons our rivers，ponds and lakes and
o（71）ceansalong with the life in them．It p（72）ollutes our soils and crops，harm trees，and can even kill fish and plants．Acid rain also eats away at our buildings．
The prevention of acid rain
Trying to prevent the pollution that gets into the air is n（73）ecessary．Keep the electrical appliances off while they are not in use．We can also use different ways of traffic to make less use of fuels．
Research tells us that acid rain harms our e（74）nvironment．So people around the world can take small steps now to make a d（75）ifferenceto our kids．
