Do you think the animals can understand each other? The answer is yes. They can communicate to each other by signs and sounds. For example, dogs communicate in many ways. They not only bark, even they howl, growl, snarl, and whine. They lift a paw, or bare their teeth. Other dogs can understand what these sounds and actions mean_.
Animals communicate with each other not only with sounds and movements but with smell. Most animals that live in herds depend on smell to keep together. And, of course, we know how dogs recognize each other by smell.
Apes are supposed to be among the most intelligent of animals, yet, they really have no better “language” than other animals. They make many sounds and expressions of the mouth to communicate their feelings of anger or hunger or joy, but they have nothing like the words of human speech.
By the way, unlike human beings who have to learn how to talk, apes and other animals know their “language” by instinct. They will make the right kind of cries and sounds and expression even if they have never seen another animal like themselves before.
Birds, however, learn their way of singing, at least in part. That is why a sparrow brought up among canaries will try to sing like one. It has been learning the wrong “language”!
the human race is only one small species in the living world. many other soecies (1)exist on this planet. however, human beings have a great influence on the (2) rest od the world. they are changing the environment by building cities and villaghes (3)where forests once stood. they are changing weather(4)conditions by citting down trees in the forests. and they are destroying the air by adding(5)pollutants to it.
it can be said that human beings are changing the environment in all(6)respects in two serious consequences. the first is that many kinds of rare animals are killed. the second is that the environment where these animals are living is (7)badly destroyed. as a result, the number of rare animals is(8)decreasing so rapidly that they are in danger of(9)extinction
