The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even eat it.

   Man has been polluting the earth. The more people, the more pollution. Many years ago, the problems 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, man 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 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 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 pollutions. It is caused by heavy traffic. We are 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 pollution at the same time.

Dear Peter

How about your study? It's Sunday today. I'm writing a letter to you. I'm going to tell you something in Beijing.

    Beijing is different from London. In our country, we drive on the left side of the road, but here people drive on the right side. Most people go to work by bus or by bike. The rush hours are from seven to nine in the morning and five to seven in the afternoon. People in China work around eight hours a day, five days a week. They usually begin to work at eight in the morning, and rest on Saturday and Sunday.

I have Chinese classes every morning from Monday to Friday. The students in our class are from many countries. We're all working hard and friendly to each other. The Chinese students are ready to help us with our Chinese. We also help them a lot with their English. We are getting along very well.

That's all for today. Please write to me soon.

               Yours

                    Susan

A young American doctor was sleeping when suddenly his doorbell began to ring. It was already midnight, but what could the doctor do? He had to get up, put on his coat and go downstairs.

When he opened the door, he saw a man standing with a hat in his hand. “How do you do?” said the man,“ Can you come at once to a place out of town? It’s quite far but you have a car and I can show you the way.”

“Certainly,” said the doctor, “I’m quite ready. I can come at once.” After a few minutes the car was standing at the front door, the man got into the doctor’s car, and they drove off.

They drove on for a long time. Then the man said, “Here we are. This is my home. Now I can pay you and you can go back to town.”

“I must see the patient. How can I go back without seeing the patient?”

“There is no patient,” explained the man. “Nobody is ill. I live here, you see, and one must get home from a town, mustn’t he? There are no taxis this time of the night, but a doctor often makes night calls, so excuse me. Here is money. Thank you, doctor. Good night.”
