                                                                    Pollution    

     Hundreds of years ago, life was much harder than it is today. People didn't have modern machines.

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 polluted 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.     

     Rules are not enough. Every person must help to fight pollution.
