Fight with pollution

Hundreds of years ago, life was 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 pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution 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 (被状物) 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, and they mustn’t let dirty smoke go into the air.

We need to do many other things. We can put waste things in the dustbin and do not throw them 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.

   Three men arrived in New York for a holiday. They stayed in a very large hotel and their room was on the forty-fifth floor. In the evening, they went to the theater and came back late. “I’m very sorry, ” said the attendant of the hotel. “The lifts are not working tonight. Do you want to walk up to your room or sleep in the hall for the night?” “Oh!” said one of the three, “We do not want to sleep in the hall. We’ll walk up to our room.” He turned to his two friends and said, “I think we can walk up to our room more easily. On the way, I’ll tell you some jokes, and then you, Alan, will sing us some songs and then you, Peter, will tell us some interesting stories.” Then they began to walk up to their room. Tom told the jokes. Alan sang the songs. At last they came to the forty-fourth floor. They felt tired and stopped to have a rest. “Well,” said Tom, “it’s your turn now, Peter. Please tell us a long and interesting story with a sad end.”

“OK, I’ll tell you a sad story,” said Peter. “It is not long, but it’s the saddest story of all. We left the key to our room in the hall.”
