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 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 give off. When these gases mix with rain, acid rain forms. Many power stations burn fuels in order to creat 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(毁坏)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, television, and other electrical appliances if you are not using them, Walk or take a bike whenever possible. If you 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 for future generations.
【小题1】When power stations burn fuel,_______.

根据材料内容选择最佳答案，并将其标号填入题前括号内。
These days, when the world seems to be hard to control, walking can make you feel peaceful. It gives you a chance to slow down, to relax and to appreciate yourself and your life in general. It helps you slow down enough to breathe deeply, to calm your thoughts, and to research the natural world filled with wonders. And yes, to love yourself more.
Try to spend one day for a long travel on foot—far from the requirements of work and family. First, choose a date and mark it as your “relaxing day”. Next, choose a place that you want to visit on foot. If you enjoy being out in nature, head to a wide and open place. Try to choose a place that’s no more than 15 minutes from your home. You want to spend your time walking, not driving.
Walk at an easy speed so you can walk longer and farther. If you normally walk two miles a day, go for four to six miles. Wear comfortable clothes. If it’s warm, wear a hat to protect your face. And don’t forget your sunglasses— not only to protect your eyes but also to give you a sense of privacy while you walk.
Before you go out, get up early so you can spend a few minutes relaxing. Relaxing is something few people spend in their spare time, but it leaves you feeling much lighter and less annoyed. Read something relaxing before you leave home, and it’ll put you in a different condition of mind. And, of course, eat a healthy breakfast and drink plenty of water. Then pick up your backpack and head out. And enjoy yourself.
