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（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.

You’ve probably known the crazy traffic in Beijing. Sometimes the cars could hardly move for a long time. The terrible traffic is caused by the poor road and China’s ability to cope with (對付) so many cars on the road at the same time.
With more Chinese people buying cars every day, the problem seems to only get worse. But a design company called Shenzhen Hashi Future Parking Equipment has a possible solution: the super bus.
The super bus would carry up to 1,400 people in its passenger compartment (隔間). It would travel on a rail system that would be elevated (升高的) above the roads, so cars could drive under it. The bus will run on electricity and solar power, creating far less pollution than that from the cars it would be replacing (代替).
Beijing authorities haven’t decided whether to create railways for the super bus throughout the city. But they are willing to give it a test drive. Later 2010, the company will test for the first time and in 2011 and 2012, the company will test the super bus with passengers.
