Many animals use some kinds of “language”. They use signals with meanings. For example, when a bee has found some food, it goes  1   its home. It’s  2   for a bee to tell the other bees where the food is by speaking to them, but it can do a little dancing. This tells the other bees where the food is and  3   it is.

Some animals show how they  4   by making sounds. It’s not difficult to tell if a dog is angry  5   it barks(吠). Birds make several different sounds and  6  has its own meaning. Sometimes we humans make sounds  7  . We make sounds like “Oh” or “Ouch” to show how we feel about something or when we  8   something on our feet.

We humans  9   have languages. We have words. These words have the meanings of things, actions, feelings or ideas. We’re able to give each other  10   to tell what we think or how we feel. By writing down words, we can remember what has happened or send messages to people far away.
