They tend to render directly what is their own way of speaking into the target language,causing a misunderstanding of illocutionary act in the hearer and a loss of illocutionary force,as a result,leading to pragmatic failure.

This paper defines cross-cultural pragmatic failure as cross-culturally communicational breakdown caused by different illocutionary forces mapped to the same lexically-grammatically correct utterance by Addresser and Addressee.

Drawing on John Searle s Speech Act Theory,this article explores performances and functions of illocutionary force in discourse by conducting an in-depth discourse analysis of the Chinese classic drama Sunrise by Caoyu.

The article attempts from pragmatics angle to adopt Cooperative Principle of Grice and context theory to carry out investigation and discussion on implicature.

A pun itself has the nature of ambiguity, so it violates the maxim of manner in CP and products implicature.

This thesis is divided into three parts: the first, the summary of the implicature; the second, the cause of formation of the implicature; the third, the realization of the implicature.
