There was no modern medicine, either.
Life today has brought new problems.One of the biggest is pollution (污染 ) . 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 become angry more easily. Air pollution is the most serious kind of pollution. It"s bad to
all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it
is like a quilt over a city. This kind of quilt is called smog (烟雾).
Many countries are making rules to fight pollution. Factories must now clean their water before it is
thrown away. They mustn"t blow dirty smoke into the air.
We need to do many other things. We can put waste things in the dustbin and not throw it on the
ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
that time.

| 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 dirty. Pollution comes in many forms. We see it, smell it and drink it. Pollution is beginning to do harm ( 损害，伤害) to our health, and even to our life. Man has been polluting the earth from the time he first made his fire9 washed his clothes in the river and threw his rubbish on the ground. Many years ago, the problem was not so serious because there were not so many people. All the dirty things would soon be covered up. There was plenty of clean air, land and water. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world. Talking about pollution, we once only meant air pollution. It is true that air pollution is still the most dangerous now, but it is only one kind of pollution. By using poison ( 毒药), we have polluted the land and killed the animals. By putting dirty water into river and lakes, we have polluted our drinking water and killed the fish. The rise in population is part of the problem. More people, more rubbish. Where is this all to end? Are we turning the world into a big rubbish dump, or is there any hope that we can get rid of ( 摆脱，除去) pollution? We are glad to say that the public has been warned of the dangers of pollution and a large number of people are working hard to get rid of it. | |

| Why do we need to throw less away? There are two reasons. One is that some resources (资源) are nonrenewable (不可再生的) That means there is only a certain amount of that resource in the world . One example of  this is oil. When we use up all the oil in the world, there will be no more.There is another reason for throwing less away. All of our trash has to be put somewhere. Often , it is put into garbage dumps (垃圾场). Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash. There are three ways to cut down on trash. One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspaper may become paper bags. A glass jar can be melted(熔化)and made into a bottle . Another way to cut  down on trash is to reuse things. You can wash and use again a bottle that can hold mustard (芥末酱)or something else .The third way to cut down on trash is to reduce the amount of trash you make, stop buying thing that you don"t need in the first place. That reduce the amount of the earth"s resources that you use. | |
