1979 was World Conservation (自然保护) Year. The United Nations wanted everyone to know
that the world is in danger. They hoped that governments would go into action (采取行动) quickly  
in order to conserve nature. Here is one example of the problems. At one time there were l,300
different plants, trees and flowers in Holland, but now only 860 remain. The others have been
destroyed by modern man and his technology (技术). We are changing the earth, the air and the water,
and everything that grows and lives. We can't live without these plants. lf we continue like this, we will
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 td 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 conversation' through a record
called  No one's going to change our world. It was made by the Beatles, Cliff Richard and other singers.
The money from it will help to conserve wild animals.

     1970 was World Conservation (保护) Year. The United Nations 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 1300 plants and flowers in Holland, but now
only 866 are left. The others have been destroyed (毁坏) by modern man and his science. We are changing
the earth, the air and the 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 is more important to ask "What must we do?" More and more
young people have known this. Many of them are helping to save our world. For example, they plant trees. In
a small town in the USA a large group of girls cleaned the banks of 11 kilometres of their river. Young people
may hear about conservation through a song called "No one's going to change our world". It was made by
Cliff Richard and other singers. The money from it will help to conserve tigers, elephants and pandas on the

     The undersea world is very beautiful. Now more and more people want to dive in the water to find the
secrets there. Scuba diving is a new sport today. It can take you into a wonderful undersea world.
     You will find many strange animals in the sea. Some are as large as a school bus. Many sea animals give
out light in the dark and some have sharp teeth.
     During the day, there is enough light. Here, under the sea, everything is blue and green. When fish swim
nearby, you can catch them with your hands. When you have bottles of air on your back, you can stay in
deep water for a long time. However, you can't dive too deep. And you must be very careful when you dive
in deep water.   
     The deep sea is not an easy place to live in. It's cold, and it's dark, too. The deeper it is, the less sunlight
there is. At about 3,000 feet, there is no light at all. It is dark in the sea. Many fishes have no eyes. Some have
big eyes. A few have eyes on one side.
     Besides (除了) the cold and darkness, deep-sea animals face a third danger---other animals. Animals eat!
They must find food to eat. Many animals eat plants. However, some animals eat meat. This means these sea
animals have two big jobs. They need to find animals as food, and they have to try not to become other animals' meal.
