Communicative function of English euphemism in pragmatic context;

Comparison of set phrases between English and Chinese in pragmatic context;

This paper holds context can be separated by semantic context and pragmatic context.

The rules and motivations are: the self-adjustable function of lexical meaning system;the restricted function of contextual interpretation;the switching function of the deep guiding of psychological mechanism and the reasoning function of discourse understanding related to communication.

In the process that monosyllable adverbs like "dou"(都),"ke"(可),"ye"(也),"also"(并),"you"(又)and so on are changing into functional modal adverbs,the pragmatic routinization plays the key role;the contexts which cause such routinization are "the rhetorical question","the interrogative question","the contrast","the negation" and so on.

Based on this fact and inspired by some ideas in pragmatic and communicative studies, the thesis uses illocutionary act, pragmatic context and pragmatic texture to construct a macro framework, in which text pragmatic production of translations is analyzed.

Through a study of this structure,this article attempts to find out the reasons and rules in the aspects of syntactic features and pragmatic contexts,in hope to instruct and regulate the special usage of variations.
