1970 was "World Conservation Year". The UN wanted everyone to know that the world was in danger - they hoped that governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only remain 860. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives here. We can't live without these things. If it continues like this, we shall destroy ourselves.

       What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record called NO ONE'S GOING TO CHANGE OUR WORLD. It was made by the Beatles and other singers. The money from it will help to conserve wild animals.

    I can't remember when I started collecting litter（垃圾）. But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.

I live close to a forest in Ohio, America. I can walk there in three minutes! I used to love going there to play with my dog. But one day there was so much litter there that I became very unhappy. I decided to clean up the forest. I wanted to feel happy going there again.

    I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was full! It had cans, bottles, broken glass and newspapers in it.

    Since that first trip three years ago, I've gone to the forest four times a year to pick up litter. I'm often there for three hours. It makes me feel great to do something for the environment.

    After each trip, I look at all the litter I've found. If any of it is recyclable（可回收的）, I keep it. I can't understand why people drop litter. But I will keep picking it up until they stop dropping it.

    I know I can only do a small bit to help the earth, but I still think it is important.

    Last week I read a report on a charity show. The aim of the show was to 1 money for the poor children who were out of school 2 their families didn't have 3 money for their children. 

    Many famous pop stars 4 the charity show, such as Jackie Chan and Lin Junjie. The stars didn't 5 any pay (报酬). They did that for free. There were a lot of performances, including singing and dancing. The audience were 6 excited that they clapped their hands (鼓掌) from time to time. Of course, the show was 7.

    All the people followed the 8 examples. They gave their money to the charity show. Both the ticket money and the donated money would be sent to the poor areas and some of the poor children would get back to school.  

    Now many charity shows 9 in our country, not only to support education in poor areas but also to help people in trouble. I hope the whole world will become more and more beautiful 10 people's help.

Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel. One group held a special event to display（展示）new kinds of cars .The new cars are different and they can run on many different kinds of fuels.

Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels. One kind of them runs on a special fuel cell which is filled with a gas called hydrogen.

      The fuel cell cars are also better in another way. They give off no emissions（排放物）. They are very clean, and don't give off bad fumes when they are running.

One man who makes fuel cell cars is excited about the hydrogen fuel cell technology. He says we will never run out of the sources of the fuel, but we may run out of the oil. Once we use oil up, it will take millions of years for more oil to form. Since gasoline is made from oil, that could be a problem for companies that make traditional cars, and for drives. However, it won't be a problem for cars that run on fuel cells.

      Buses that run on hydrogen fuel cell power are being tested on the road. They could become a common form of transportation in the near future
