Germs are always in dirty water. When you look at dirty water under a microscope, you will see them in it. So your parents will not let you drink dirty water.
Germs are found not only in dirty water, they are also found in air and dust. If you cut your finger, and if some of the dust goes into the finger, it will become big and red, and you will have much pain in it. Sometimes they will go into your body and you will have pain everywhere.
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.
The world itself is becoming much smaller by using modern traffic and modern communication equipment(通讯设备). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it. Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, people moved to another place. They are slowly polluting the whole world.
Air pollution is still the most serious. It's bad for all living things in the world but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight against pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air.
Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time.
One day in April, a special activity called "Food Street" was held on the playground at Railway NO. 1 Middle School in Xi'an. This activity was part of the English Art Festival in the school. The students in each class were divided into several groups. And each group sold different kinds of food. The students did the shopping and the cooking all by themselves. The students cooked delicious food such as fried chickens, potato chips and vegetables. They all worked hard and sold the food at low prices. The customers, who were the junior students, teachers and parents, all praised them for the nice food.
"It's really hard work," said one of the students who took part in the activity. "We must make a plan before the cooking. We must know how much we should spend on the things we need. Also, we must learn how to serve customers well."
"This activity is to give a chance to the students to develop their practical abilities," said one teacher. "What's more, the students will not only learn how to make money by their own hands, but also know the meaning of life."
