| Many animals use some kinds of "languages". They use signals (信号) and the signals have meanings. For example, when a bee has found some food, it goes back to its home. It is 1 for a bee to tell the other bees where the food is by speaking to 2 ,but it can do a little dancing. This tells the bees where the food is and how far it is. Some animals show how they feel by making sounds. It is not difficult to tell if a dog is angry 3 it barks (吠). Birds make several different sounds and each has its own meaning. Sometimes we humans make sounds 4 . We make sounds like" Oh" or" Ouch" to show how we feel about something or when we drop something on our feet. We humans have languages. We have words. These words have the meaning of things, actions, feelings or ideas. We 5 give each other messages to tell other people 6 we think or how we feel. By writing down words, we can remember what has happened or 7 messages to people far away. Languages, like people, live and die. If a language isn't used by people, it is called a dead language. This language can not live and grow because 8 speaks it. Latin is an example of a dead language. A living language, of course, is often spoken by people today.It grows and changes with time. New words are created (创造) and some old words have 9 meanings. Some words, or their meanings, may even die and only be found in the old books. English and Chinese are 10 examples of a living language. | |||
