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.
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 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.

One day a snake was looking for food. She found a hole and went into it. “Hooray!” It was a house for mice. She said to herself happily. There, she saw some little babies of mice. “They are good dinner for me!”
She came to them and asked, “Where are your parents?” The babies answered, “They went out for food.” “Food? Good!” said the snake. “Come on and listen to me. I came here to see your parents and tell them not to steal the people’s grain any longer or I will kill you all.” The little mice worried about their own safety. “Don’t be afraid, my body is like the hole. It is a safe place. When I open my mouth, you can come into it one by one. Then we will wait for your parents coming back. Are you clear?” The little babies came into the snake from her mouth one by one.
A moment later, the mice’s parents came back with some grain. Just then they found a snake in their room. “Who are you? Why did you come into our house?” “Where are our babies?” asked the mice’s parents. The snake answered coolly, “I am a judge of the people. I knew you did a lot of bad deeds. You often steal lots of food stuff of the people. Today, I came to sentence you to death. Your babies have been in my body. Don’t you want to see them?” With these words, the snake flew at the mice.
