问题:

   You speak, write a letter, or make a telephone. Your words carry a message. People communicate

with words. Do you think you can communicate without words? A smile on your face shows you are

happy or friendly. Tears in your eyes tell others that you are sad.

    When you put up your hands in class, the teacher knows you want to say something or ask questions.

You shake your head , and people know you are saying"No". You nod and people know you are saying "Yes". Other things can also carry messages. For example, a sign at the bus helps you to know which

bus to take. A sign on the door helps you to know where to go in or out. Have you ever thought that
