【摘要】：The American linguistic philosopher Grice proposed the important "Conversational Implicature Theory" in the lecture at Harvard University in 1967, and its related theories reveal language norms to guide the two sides of conversation in the process of communication. It contains a series of maxims which help both sides of the conversation to accomplish the dialogue smoothly. So the Cooperative Principle is one of the important guides for people's speech communication. Under the guidance of CP, implicating meaning comes out, Grice calls that Conversational Implicature(CI), when speakers violate the maxims of CP on purpose. CP, as a discipline mediating between linguistics and audiovisual criticisms, has gathered more attention in recent years from scholars in the area of audiovisual criticism as well as audiovisual studies. Application has been wider and wider. Through the analysis of dialogues between characters in the work and discussion about the comprehension of the whole meaning in communications, the listeners could get through the literal meaning to the deeper intention. So the real intention of the speaker violating the Cooperative Principle can be found and the sense of humor can be shown.
