The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). 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 a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain 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 try to control the growth of population at the same time.

I heard the bees long before I saw them.

It was a very hot afternoon, and we decided to cool off in the river near my home. As we climbed down a small rocky hill toward the water, my boyfriend John suddenly started to shout then jumped into the water below. Peter and Mary quickly followed but I was too far away to jump. I was trapped.

I heard a low hum(嗡嗡声)，which was growing louder. From a distance, the group of bees looked almost like a cloud of smoke. As it got closer, I realized it was actually thousands of bees flying towards me.

All I could do was cover my face with hands. Crazily, I thought that if I sat very still, the bees would think I was just another rock.

After a few minutes, I knew my plan hadn’t worked. The bees were attacking me. I could hear my friends shouting at me to get down to the pool fast.

But it wasn’t so easy. I was in great pain and the only way I could get away was to use my hands to climb down the rocks. However, I was afraid to do that at first because my face would be unprotected. The noise the bees made was so loud and frightening, but I had no choice.

I rushed down the rocks and jumped into the pool, but I don’t remember doing it. I was just so happy to be free from the pain. I was safe, and the water felt wonderful.

But we still weren’t out of danger. Every time we tried to climb out of the pool, the bees flew back over our heads. We spent the next three hours in the water, putting our heads under the water from time to time to avoid the bees until they finally lost interest.
