Students often adopt word-for-word translation method and produce many awkward Chinese-style English and English-style Chinese in their translation practice, which results from a lack of discourse awareness among college students.

And in translation activities, the use of metadiscourse embodies the discourse awareness of the translator, which helps the translator convey the thought of the original text faithfully and smoothly while conforming to the nature of the target language.

This paper,based on the framework of the three metafunctions and projection in systemic-functional grammar as well as the related analytical principles of code-switching,aims to explore the interpersonal meanings and textual meanings of code-switching in projected message.

Beginning with a brief introduction of some basic theoretic knowledge about text, this paper, by making a theoretical analysis of some translation examples, discusses the importance of the translator s textual awareness in both comprehension and representation of the translation process.

To breach the ethnocentrism,cultural narcissism and imperialism of the West,to introduce the Chinese classics to the dominant culture and to make the East and the West co-exist and be mutually beneficial to each other in the development of a harmonious world,translators should have cultural awareness on the one hand and textual awareness on the other.
