Hundreds of years ago, life was harder than it is today. People didn’t have modern machines. There was no medicine, either.
Life today brings new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly.
Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
Rules are not enough. We should do our best to fight against pollution.

Have you ever been ill? When you are ill，you must be unhappy because your body becomes hot，and there are pains all over your body. You don't want to work，you stay in bed，feeling very sad.

　　What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with your eyes，but you can see them with a microscope. They are very small and there could be hundreds of them on a very small thing.

　　Germs are always found in dirty water. When we look at dirty water under the microscope，we shall see them in it. So your father and mother will not let you drink dirty water. 

　　Germs aren't found only in water. They are found in air and dust. If you cut your finger，if some of the dust from the floor goes into the cut(割开处)，some of the germs would go into your finger.

There are some easy things you can do to protect(保护) the environment and the earth. Choose ideas from the list or come up with a few of your own.

● Plant flowers, grass or trees.

●Whenever you visit a park or beach, take away what you bring there----keep rubbish in a bag until you can put it in a dustbin (垃圾箱).
