The plants must have it. The animals must have it. We must have it too. We cannot live without drinking water. Sometimes, we do not have all the water that we need. The land will dry up without water. Sometimes, there can be too much water in the land. If it rains very, very hard, the rain water will run down the hills. It takes some of the land with it when it runs down the hills. It is called erosion（侵蚀）when the water takes the land away.

    　　Water on the earth will never be used up. It goes from the ocean to the air to make clouds. Then, it falls from the clouds down to the land. It runs off the land out to the ocean again. The clouds in the air are made of water. Sometimes the water fall down from the clouds.

         1970 was World Conservation (保护) Year. The United Nations wanted everyone to know that the world
    is in danger. They hoped that governments (政府) would act quickly to conserve nature (保护自然). Here is
    one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland but
    now only 866 remain. The others have been destroyed by modern man and his technology. We are changing
    the earth, the air, the water and everything that grows and lives. We can't live without these things. If things
    go 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 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 number of girls cleaned the banks of 11 kilometers of their
    river. Young people may hear about conservation through a record called "No one is going to change our
    world." It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve
    animals.
    (     )1. The United Nations wanted everybody to know that the world is in danger.
    (     )2. There are fewer plants, trees and flowers in Holland because many kinds of plants, trees and flowers
                can't grow there any more.
    (     )3. The most important thing for us to do is to clean the banks of our rivers.
    (     )4. "No one is going to change our world" is a name of a song.
    (     )5. From this passage we know that we must conserve nature.
