Every time you turn on the television or take a ride in a car, you could be adding to a problem called acid rain(酸雨). In this article, you’ll learn how acid rain is created, and how it affects us, and more importantly, what we all can do to prevent it.
How is acid rain created?
When people use fuels(燃料), such as coal and gasoline, poisonous gases are given off. When these gases mix 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 mixes with these gases, harmful things called acids form. This is acid rain.
How does acid rain affect us?
Acid rain damages everything that it touches. It poisons our rivers, ponds, lakes, and oceans along with all the life in them. It pollutes our soil and crops, harms trees, and can even kill fish and plants. Acid rain also eats away at buildings. How can we prevent acid rain?
We need to cut down on the pollution that gets into our air. Turn off lights, televisions, and other electrical appliances if you are not using them. Walk or take a bike whenever possible. I f you are traveling 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 for future generations.

When you cough or sneeze, please turn your head away from others and cover your mouth with the full part of your hand. Afterwards, you should say, “Excuse me.” This is a rule I set for my students.
It is so simple, but many kids have never been told to do this. In fact, I notice adults cough and sneeze in public without putting a hand over the mouth. I hate traveling by subway（地铁）in New York during cold and flu season, because it is certain that someone is going to stand right behind me and cough or sneeze on my neck.
One important thing I point out to the kids is that after they sneeze or cough on their hand, they should wash their hands as soon as possible. Otherwise, they will be passing those germs(病菌)along to everything and everyone they touch.
In order to help the kids remember this rule, I tell them about an old story. It says that when you sneeze, evil spirits jump into your body. If you don’t cover your mouth, the spirits will enter, but if you cover your mouth, you will keep them out. We say “God bless you” when some sneezes, and in Germany you should say “Gesundheit.” That means “Good health to you.” Both expressions are said just in case you didn’t cover your mouth in time and the spirits were able to enter your body. The kids love finding out the origins(起源) of these expressions and it encourages them to put the advice to use more often.
