Crosstalk is a unique humorous art form in our country and it brings lots of fun to us. This paper mainly analyzes the humor mechanism of crosstalk according to the context differentia in the rhetoric and also discusses the reasons about the context differentia caused among the crosstalk based on the co-relation theory. We believe that context differentia in the crosstalk has two aspects:On one hand, the variation of context in the crosstalk causes the people’s strange feeling. On the other hand, the two conflict contexts produced by the crosstalk under the special art from. These two context differentia made the crosstalk full of humor and satire. The reason of casing this context differentia, according to Wilson co-relation theory, is basically because of the context dynamics and also related to the actors’ reasoning action. The maximum relevance and optimal relevance in the context differentia are the ligaments between the actors and audience. |
