Abstract: Verbal behavior is the means which is used in concrete context torealize communicative purpose. And Speech Act Theory taking verbal behavior as its research subject，focuses on the deeds accomplished via uttering certainremarks and is one of the well-established and important fields of pragmatics, which holds the attention of both linguists and philosophers. Two partsinvolved in the theory are speech and act, with linguists focusing on the former and philosophers on the latter respectively. Since 1953 it has beena commonly accepted assumption in English and American linguistic philosophy that speeches function as rule-governed acts. English philosopher Austin is apath-breaker in this aspect for the Speech Act Theory he put forward, which is a significant breakthrough in pragmatics. The gist of the theory is that inuttering sentences, one is also doing things. According to Austin, there are three senses in which in saying something one is doing something; hence threekinds of acts are simultaneously acted. An American philosopher John Searle, also a student of Austin, holds Austin's Speech Act Theory only critically, andhe revised it, and this theory becomes one of the core theories in pragmatics. Both Austin and Searle attach great importance to the understanding of thespeaker's intention or force, for listeners can respond in an expectant manner only when he understands the intention or the force expressed through theillocutionary act performed by the speaker concerned. To achieve this, people involved in verbal communication, especially in cross-cultural context, shouldbe armed with the knowledge of Speech Act Theory. Therefore, the paper makes a tentative endeavor to analyze speech acts in cross-cultural context from theperspective of linguistic philosophy and explore the steering function of the western research findings in linguistic philosophy, Speech Act Theory inparticular, in cross-cultural communicative activities.
