Abstract: Brown and Joseph Richmond Levenson put forward a theoretical model of face threatening behavior and its corresponding strategies, and made an in-depth study of politeness. It is different from Grice's cooperative principle and Leech's politeness theory, but it clearly reflects the interactive relationship between social communication and human flexible thinking. This paper intends to study the significance of face threat theory from the perspective of social psychology, using the reflective evaluation theory of social cognition and the theory of conflict management mode, combined with syntactic characteristics.

1. Introduction

Brown and Joseph Richmond Levenson believe that Grice's framework of cooperative principles is correct in essence, and that outspoken and face-threatening behaviors also follow Grice's guidelines in a sense (1987: 94). What are the four principles of the cooperative principle? Is it a convention in verbal communication? (Liu Runqing, 2006: 154), as a guiding principle to achieve maximum effect. However, although Grice further supports his theory with conversational implicature theory and explains non-cooperative speech acts that obviously violate the cooperative principle, it does not explain clearly the fundamental motivation of people to generate and understand discourse. For example, X is a student of A, and he wants to find a job, so A wrote him a letter of introduction, as follows:

Dear sir,

Mr x? Scommodofenglish sexcel and totutorialshasbeenregular.

Yours, here.

The letter didn't provide enough information for the letter of introduction, so it violated the principle of quantity. Nevertheless, we can still infer the implied meaning of A, but on the other hand, we can't grasp his motivation to provide a small amount of information. Leach (1983: 80) thinks that the cooperative principle (cp) can explain the propositional meaning in truth semantics, but it can't explain why people don't express their intentions directly. In view of the deficiency of the cooperative principle, he put forward the politeness principle. PP is not a necessary supplement to CP, but to save CP from the predicament? (ditto). As far as the previous example is concerned, he thinks that the praise standard of PP seems to be explained. Besides. Leach also intends to use social and psychological orientation to study how pragmatic principles are applied in a wider range, which shows that politeness is the main motivation for people not to specify.
