问题补充：
of years ago, life was much harder than it is today. People didn’t have modern machines. There was no modern medicine,__.
Life today has brought new. One of the biggest is pollution of our drinking water. 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 a city. This kind of quilt is called smog.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, and they mustn’t blow dirty 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 or with our friends in car. If there are fewer people driving, there will be pollution.
Rules are not .Every person must help to fight pollution.
