Abstract: Metaphors are pervasive in political discourses. Given that using metaphor effectively can lure supporters to their sides, politicians prefer to take advantage of conceptual metaphors to construct their political discourses, and to fulfill their aspirations. Therefore, the study of conceptual metaphors in their political discourses can help us find the trends of their political attitudes effectively. With the theoretical framework of Conceptual Metaphor Theory, this paper analyzes metaphorical expressions in Obama’s State of the Union Address in 2016 and finds out four major types of conceptual metaphors: war metaphor, journey metaphor, building metaphor, and human metaphor, and their functions in political discourse. The use of conceptual metaphor not only reduces the audience's burden in comprehension with simple concept, but also helps to arouse the audience's emotions and persuade people to accept political views and reform measures. 

Key words: conceptual metaphor; political discourse; State of the Union Address
