閱讀下面短文，根據(jù)其內(nèi)容，從短文后所給的A、B、C、D四個選項中，選擇最佳答案。

  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. 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 for all the living things in the world.

  Cars, planes and factories all polluted air so thick that it is like a quilt (被子) over a city. This kind of quilt is called smog (煙霧).

  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.
