    Do you think you can communicate    1  words? A smile on your face shows you are  2   ．Tears in your eyes tell others you are sad．When you  3   your hands in class，the teacher knows you want  4  something or ask questions． You shake（摇动）your head，and people know you are saying    5   ．

    Other things can also carry messages．For example，a sign at  6  helps you to know which bus it is．A sign on the wall at your school helps you   7   the library． Sign on the door tells you which go in or out．Have you ever notice（注意）that there are lots of signs round you and that you receive messages  8   them all the time? Books， newspapers，TV, radio and  9  all help us to communicate with other people．They all help us  10  what is going on in the world and what other people are thinking about．
