Ever since humans lived on the earth，they have made BSC of various forms of  communication．Generally, the expression of thoughts and feelings has been in the form of oral  speech．When there is a language difficulty, communication is carded out through sign language in which movements stand for letters，words and ideas．Tourists and the people unable to hear or speak have had to use this form of expression．Many of these symbols of whole words are very vivid（生动的）and exact and can be used internationally；spelling，however, cannot.

Body language passes on ideas or thoughts by certain action, either on purpose or not. A wink（眨眼）can be a way of indication that the party is only joking. A nod means one agree, while shaking the head indicates “No”.

Other forms of nonlinguistic language can be found in Braille（a system of raised dots read with the fingertips）, signal flags, Morse code（莫尔斯电码）and Smoke signals. Road maps and picture signs also guide, warn, and instruct people. While language is the most common form of communication, other system and techniques also express human thoughts and feelings.
