Each nation has many good people who help to take care of others.For example,some high school and college students in the United States often spend many hours as volunteers in hospitals,orphanages or homes for the aged.They read books to the people in these places,or they just visit them and play games with them or listen to their problems.Other young volunteers go and work in the homes of people who are sick or mow their lawns.For boys who no longer have fathers there is an organization called Big Brothers.College students and other men take these boys to baseball games or on fishing trips and help them to get to know things that boys usually learn from their fathers.Each city has a number of clubs where boys and girls can go to play games or learn crafts.Some of these clubs show movies or organize short trips to the mountains,the beaches,museums or other places of interest.Most of these clubs use a lot of high school and college students as volunteers because they are young enough to remember the problems of younger boys and girls.Volunteers believe that some of the happiest people in the world are those who help to bring happiness to others.

The earth is our home.We must take care of it.This means keeping the land,air and water clean.

Pollution is a¡°dirty¡± word.To pollute means to make things unfit or unclean to use.Pollution comes in many ways,we see it,smell it,taste it and drink it.Pollution is beginning to threaten(Íþв)our health,our happiness and our life.

Man has been polluting the earth from the time he first made fire,washed his clothes in the river and threw his waste on the ground.When land was used up or water became dirty,men moved on to another place.At first the problem was not so serious because there was plenty of clean air,land and water.There weren't so many people and then their wants were fewer.All the dirty things could be absorbed(ÎüÊÕ)by nature and soon covered over.But this is no longer true.The increase of population and the development of industry have changed that.Man is slowly poisoning his environment.

Once we thought of pollution,we simply mean air pollution.Though it is still the most dangerous,air pollution is only one type of pollution.

Through the use of poison,man has polluted the land,killing the animals.By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water,killing the fish.

Our increasing population is part of the problem.More people more waste.

Where is this all to end? Are we turning the world into a big rubbish dump(À¬»ø¶Ñ),or is there any hope that we can get rid of the pollution?

Fortunately,millions of people have been warned of the danger of pollution.Large numbers of people are now working hard to bring pollution under control(¿ØÖÆ).
