　　A rabbit is running into his hole．You may ask,“What happened?”

　　Well, when a rabbit sees something dangerous, it runs away．Its tail moves up and down as it runs．When other rabbits see this tail moving up and down, they ran, too．They know there is danger．The rabbit has told them something without making a sound．It has given them a signal．

　　Many other animals use this kind of language．When a bee finds some food, it goes back to his home．It can't tell the other bees where the food is by speaking to them, but it does dance in the air．This tells the bees where the food is．

　　But animals say things by making sounds．A dog barks, for examples, when a stranger comes near．A cat purrs(發(fā)出呼嚕呼嚕的聲音)when pleased．Some birds make several different sounds, each with its own meaning．

　　But human beings have something that no animals have－a large number of words about things, actions, feelings or ideas．We are able to give each other information to tell or inform other people what is in our mind or how we feel．By writing words down we can remind ourselves of the things that have happened, or send messages to people far away．No animals can do this．No animals has the wonderful power of language．

　　No one knows how man learned to make words．Somehow he learned to make them．As centuries went by, he made more and more new words．This is what we mean by language．

　　People in different countries made different kinds of words．Today there are about fifteen hundred different languages in the world．A very large English dictionary, for examples, contains four or five hundred thousand words．But we don't know all these．The words we know are called vocabulary．We should try to make our vocabulary larger．Read as many books as possible．When we met a new word, look it up in the dictionary．A dictionary is the most useful book．

　　In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there．Services such as hospital and transport(交通)are usually much better in the city than in the countryside．They hope that their lives will improve when they move to the city．

　　But in the big cities of Europe like London or Pads, people are moving out of the city．These rich families want to live a quieter life．They are tired of the noise and the dirt(塵土)of the city, and they are tired of the crowded streets, crowded trains and buses．They don't want to live in the cities any more．They want a house with a garden in the countryside, and breathe the fresh air there．

　　So they move out of the cities．Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields．There, they start new lives and try to make new friends．

　　Not all those who move from the city to the countryside are happy．After two or three years, many people who have done this feel that it was a big mistake．They don't make so much money and there isn't much work to do．People in the countryside are very different and aren't always very friendly．

　　As a result, quite a lot of people who have moved to the countryside move back to the city．“It's wonderful to see crowds in the streets and cinema lights,”they say．
