When people talk to each other, write letters or make phone calls, words of the spoken form or the written form can send any messages they want to pass on.

But besides words, do you know any other ways you can use to communicate with people? Rich expressions on your face can be one of them. A smile on your face shows that you are happy. Tears in your eyes tell others that you are sad or excited. Body languages can do the same job. When you put your hand up in class, the teacher knows that you want to say something or you may have some questions to ask. You shake your head from side to side and people know you are saying "no" or disagree to others' requirements. When you nod, people will understand that you are saying "yes" or agree to others' opinions or suggestions.

Other forms can also carry different messages. For example, a sign at the bus stop gives passengers instructions on which bus to take. Sound from the school bell tells the students and the teachers when to begin or end a class. Music and films also convey the feelings and ideas of the musicians and the directors. So next time when you see a piece of art or listen to some music, take it as communication with its creator and try to get the meaning behind it.
