Abstract
This paper aims at studying linguistic expression in its basic form and in its role as the basis of the composition guidance theory. Therefore the author looked at the same linguistic functions in communication and dealt with them organically and structurally. By quoting from Ferdinand de Saussure ' s linguistics the author emphasized that linguistic expression is not only for conveyance of meaning but also for systematizing the reality in the value system of the recipient. By phenomenology the author looked at expression in a way which had not been discussed in Ferdinand de Sassure's linguistics. The author also advocated that more importance should be attached to creative imagination with regard to linguistic expression. These points of view have not been considered greatly in previous studies on composition guidance, so the author has put them forward as a new basic theory.
