When you speak, write a letter or make a telephone call, your words carry messages. People communicate with words.
Do you think you can communicate without words? A smile on your face shows that you are happy or friendly. Tears in your eyes tell others that you are sad. When you raise your hand in class, the teacher knows that you want to say something or ask a question. You shake your head, and people know that you are saying
“No”. You nod and people know that you are saying“Yes”.Other things can also carry messages. For example, a sign at a bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on the doors tell you where to go in or out. Have you ever noticed that there are a lot of signs around and that you receive messages from them all the time?
People can communicate in many other ways. An artist can use his drawings to tell about all the wonderful things in the world and also about people and their ideas.
Books, magazines, TV and radio and films all help us to communicate with others. They all help us to know what is going on in the world and what other people are thinking about.
True or false:
(1) When you raise your hand in class, you are giving a message to your teacher.
(2) Signs may tell you what to do or where to go.
(3) You can get messages from newspapers and films, but not from books or drawings.
(4) Sometimes you can know someone is sad from his face.
(5) Signs in the public places can carry messages.
