Going to work by car gets more difficult and more expensive year by year. People can do nothing about the world’s price of petrol （汽油）. They have to go to work, so they have to pay. However, some people have decided to stop driving cars to work.
People are looking for a cheaper kind of transport and they have found out that it is a good choice to ride a bike to work. More and more people return to bikes.
Children often go to school by bike. Businessmen are going to their offices by bike, too. “The bicycle is easy to use,” says Kate, a teenager who likes going to school by bike. “And it is also very cheap. It is a good choice for people. You can buy one hundred bikes for the price of a small car. A bike doesn’t use expensive petrol but runs on man power. And most bikes can be used for a long time.”
“Cycling is good for you.” said Dr. Brown. Every day he cycles to his hospital. “Drivers sit in traffic jams and get angry. They can do nothing. That’s bad for their hearts. And many of them get fat. In the 21st century people don’t get enough exercise. So I tell my patients to buy bikes. If you cycle to work, you can save petrol and money, improve your health, and also save time. In big cities, it’s quicker to travel by bike than by bus or by car.”

Once we did not think about the protection of our environment. There weren’t many people on the earth before, but now more and more people live here and there. The world has bee too crowded. Our natural resources seem to be limited. More and more resources will be used up, and more and more pollutions will make us live in danger.
Trees are cut down to make furniture. Big trees are disappearing. The forests are crying. But people are still greedy to cut trees. How long will a young tree grow up? It needs 50 years!The earth is also weeping. The area of the desertification （沙漠化） is much bigger and bigger. Animals also fail to survive. The fish in ocean has been dead a lot because of the chemical poison. Whales and dolphins kill themselves near the beach. Is it a surprise? No, I think it is a symbol of protest （抗议）. They are against human beings. It seems that they only die to awaken the human’s conscience.
We also know if the pollution continues to rise at the present rate, in a few years, there won’t be enough good food not only for beasts, but also for our human beings. What can we do to solve these problems?
Many people have seen the problems now and they are taking actions to solve it. For examples, there are more and more cities around the world taking in part in the “World Earth Day”.
