Many animals use some kinds of “language”. They use signals(信号) and the signals have meanings. For example, __1　 a bee has found some food, it goes　 2　 its home.　 3　　 is difficult for a bee to tell　 __4　 bees where the food is speaking to them, but it can do a little dancing. This tells the bees where the food is and　 5　 it is.

　Some animals show　 6　 they feel by making sounds. It is not difficult to tell if a dog is angry because it barks. Birds make several different sounds and　 7　 has its meaning. Sometimes we humans make sounds in the same way. We make sounds like “Oh” to　 8　 how we feel about __9__ or we　 10　 something on our feet.

　We humans have languages. We have words. These words have meaning of things, action, feeling or ideas. We are able to __11__ each other information, to tell other people　 12　 we think or we feel. By writing down words, we can remember what has happened or　 13　 messages to people far away.

　Languages, like people, live and die. If a language is not used by people, it is called a dead language. This language cannot live and grow because　 14　 speaks it.

　A living language, of course, is often spoken by people today. It grows and changes with time. New words are created, and some old words have　 15　 meanings.
