1970 was World Conservation (保护) Year. The UN wanted everyone to know that the world was in danger. They hoped something could be done.

    Here is one example of the problem. At one time there were about 1,300 kinds of plants, trees and flowers in Holland, but now only about 866 are left. The others have been destroyed by modern people and their science. We are polluting earth, air, water and everything around us. We can't live without these things. If things go on like this, we shall destroy ourselves.

    What will happen in the future? Perhaps it's more important to ask "What must we do?". More and more young people have known this. Many of them are helping to save our Earth. For example, they plant trees. In a small town in the United States, a large group of girls cleaned the banks of 11 kilometres of their river. Young people may hear about conversation through an album called "No One's Gonna Change Our World". It includes songs of Cliff Richard and other singers. The money from selling it will help to conserve tigers, elephants and pandas on Earth.

    My name is Sam. I joined a club called" passing help" last month: Now let me tell you why I joined it.

    One evening this May, on my way home my-old car broken down. It was 25 miles from my home.

    I wanted to get a ride, but there was no car. It was also hard to take a taxi. I decided to take a bus home. I went to bus stop nearby.

    After a while, a bus came, but it did not go to my town. The bus driver was a young woman.

    She was kind and she told me which bus I should take. I waited there for about thirty minutes, but no bus came. At last a car came to me and a woman came out of the car. She was just the bus driver.

    "When I reached the bus station, I got to know that the bus to your town couldn't come, so I returned here. I just can't leave you here," she said, "Get in my car and I will take you back to your home," "It is a long way." I said." Come on, sir," she said," Let's go."

    On the way she told me a story. A few days ago, there wasn't .gas(汽油) in her car. An old man drove her up to a gas station and then back to her car.

    When we got to my home, I wanted to give her some money to thank her, but she didn't accept. "I only want to help others and do something nice for somebody. Pass it along. "She said.
