Although interpretation has been long existing in human history

the history of simultaneous interpretation is comparatively much shorter. The debut of simultaneous interpreting (short for SI) was at the Paris Peace Conference in 1919. However

it was not until the Nuremburg Trials from 1945 to 1946 that the SI began to attract wide attention. Since then

SI has become an essential part of most business conferences

government and non-government exchange activities.Nowadays

the research work on interpretation is more likely to be associated with other disciplines

such as linguistics

psychology

sociology

and neuroscience. As a primary principle in pragmatics

the Cooperative Principle (short for CP)

put forward by Grice

has come into the sights of interpretation researchers. The CP describes how effective communication in conversation is achieved in common social situations. There are four maxims in the CP: the maxim of quantity

the maxim of quality

the maxim of manner and the maxim of relevance. Interpretation

as a special kind of conversation

also can be guided by the CP.Through the study

the paper concludes that the CP can be applied to SI to help the interpreter better understand what to do and what to avoid.
