Abstract
According to Halliday, systemic functional grammar can provide a theoretical framework for discourse analysis due to its properties of multi-level and multi-function. The study on interpersonal metaphors can trigger off our comprehensive understanding and analysis to a text. Luckily, it has attracted some scholars’ attention both at home and abroad. However, few of them employ the interpersonal grammatical metaphor for discourse analysis. Most scholars pay more attention to the study of its classification and ways of judgment instead of the study of interpersonal grammatical metaphor in discourse, especially, in a specific discourse. Interpersonal grammatical metaphor has not been attached enough importance. However, we also see that some scholars are beginning to show their interest in researching interpersonal grammatical metaphor in discourse，such as Fan Wenfang (2000),Chang Chenguang (2001). There are some graduate students such as Yu Xiaoman (2003), Wang Aihui (2005), Zhang Zhixiang (2006), Zhao Yufang (2007) who began to investigate the functions of interpersonal grammatical metaphor in specific discourse.
Owing to the important roles of interpersonal grammatical metaphor in discourse and the deficiency of the study on interpersonal metaphor in president’s weekly radio speech, this study is intended to probe into the abundant existence of interpersonal grammatical metaphor in weekly radio speech, and provide teachers and English learners with deeper insights into the interpersonal grammatical metaphor and their function on helping the president realize communicative purposes. Two research questions are formulated in this thesis: 1. what are the occurrence and frequency of interpersonal grammatical metaphors in Obama’s weekly radio speeches? 2. What are the functions of interpersonal grammatical metaphors in the discourse accordingly?

Through quantitative analysis, the occurrence and frequency of the interpersonal metaphor in the corpus are counted and compared. Moreover, through qualitative analysis, the author probes into the application of interpersonal grammatical metaphors by examining their functions in helping the president achieve his communicative goals.
The major findings are summarized as follows: First, through quantitative analysis, it is found that the speaker in weekly radio speech achieves his communicative purposes by tactically adopting a lot of metaphors of mood or metaphors of modality. Second, in weekly radio speeches, a lot of statements clarifying the policies are realized by the let me structure of imperative mood to show the speaker’s authoritativeness as a president. A metaphor of mood issuing commands with declarative mood is also widely used to shorten the distance between the president and the audience so as to gain their understanding and support. Some statements realized by interrogative mood are adopted to convey the speaker’s implications or form an atmosphere of intercommunication,www.51luwen.org depending on the situation.
