Abstract：The Speech act theory was put forward by the Oxford philosopher John Austin, and it is the first important theory dealing with the language in use. In his theory, Austin suggests that our speech itself is an act, and to say something is actually to do something. He believes that in three senses our speech can be seen as doing something, and they are known as the three levels of speech act: locutionary act, illocutionary act, and perlocutionary act. The American philosopher John R. Searle developed the theory based on Austin’s. The conversations in the TV series The Apprentice give us enough raw materials to study and analyze with the speech act theory. At the same time, we can contrast the speech acts in the speech of different people, so that we can find out the difference in the speech acts between people. Then we may find out whether the speakers can communicate effectively with others so as to successfully complete a task.
