  Dolphins are not fish, but warm-blooded animals.They live in groups, and speak to each other in their own language.In a way they are like other animals, such as bees and birds.But dolphins are very different from almost all land animals.Their brain is nearly the same size as our humans, and they live a long time-at least twenty or thirty years.

  Like some animals, dolphins use sound to help themselves find their way around.They also make the sound to talk to each other and to help them find food.We now know they do not use their ears to receive the sound, but the lower part of the mouth, called the jaw.

  Strangely, dolphins seem to like humans, and for thousands of years there have been stories about the dolphin and its friendship with people.

  There is a story about sailors in the 19th century.In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack.From 1871 to 1903, Jack met every boat in the area and showed it the way.Then in 1903, a passenger on a boat called The Penguin shot and wounded Jack.He recovered and for nine years more continued to guide all ships through the area-except for The Penguin.

  Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

  Men are the cleverest and most dangerous animals on the earth. Rats(老鼠)come second. Men kill many other animals, and they kill their enemies. They have even killed millions of men since ancient times(远古时代), but rats have killed more men. They have killed hundreds of millions of men. Rats carry many diseases(疾病)and these have killed and are still killing thousands of men today in many countries. Rats are dangerous not only in one way. They not only carry diseases into men's home, they also eat up men's food. They eat 33 million tons(吨)of grain(谷物)every day. That is enough grain to feed 200 million people. Rats are clever, too. They have good leaders(领导者). Men try to poison(毒)them, but if their leaders tell them that food is dangerous, they do not eat it. Our cities and villages are full of rats today. We can go to the moon, but we are not able to kill these small animals. Is it because this dangerous enemy is too clever and grows too fast, or we are not clever enough as well as not clean enough?

     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.
