Chapter 2　Literature Review

To pragmatics and interlanguage pragmatics the study of speech act is what the study of grammar is to language.Thus speech act theory is of fundamental importance in the present research besides the conversational implicature theory，the face-work theory，relevance theory，adaptation theory，cognitive theory，and so forth.Apart from these theories，it is necessary for us to revisit the notions and rationale of interlanguage，interlanguage pragmatics，intercultural communication，pragmatic transfer，pragmatic failure and fossilization.The reason lies in that for both students in general and ethnic students in particular，the aim of learning English is to be able to carry out intercultural communication，in which various issues and problems can be perceived in relation to ILP acquisition and development.Thus in this part we are going to parse these basic concepts followed by a review of related studies.
