| The study of dialogue, as part of "Discourse Analysis", falls into category of F. D. Saussure's" parole linguistics" which studies spoken language. Plenty of theories advanced on the study of this topic have been conducted on the types of conversation, such as everyday dialogues, television dialogues on and class dialogues, etc. As broadcast media vary day after day, live broadcast hotline programs become increasingly popular to common people and finally turn into a new type of conversation. Based on the summary of previous theories on this issue such as interpersonal strategy for politeness and power in cross-cultural interpersonal pragmatics, with live broadcast hotline programs on Xinjiang Traffic Radio Channel and Xinjiang Traffic Music Channel as corpora, this study seeks to do the following two analyses: (1) to analyse the characteristics and laws of a whole conversation structure live broadcast hotline programs so as to find a whole dialogue in such programs has obvious beginning, body and ending. The functions of the beginning are especially prominent for they direct the topic of the whole conversation program; in the body, the topic is divided into relevant sub-topics which carry out the limited transformation; the ending in form and speech use is filled with sense of art. In addition, partly structure of live broadcast hotline programs is discussed only to find that the characteristics of addressers and addressees differ in turn-taking, topic control and discourse patterns in particular contexts; (2) to prove that the host plays the core roles of linking the programs in and controlling the rate of conversation. The host shows certain characteristics in conversation and in the relationship with the audience for politeness and power. Moreover, the research is also proceeded on the host's operation of the interpersonal strategy during the program broadcast, the presentation of the polite relationship and the application of inductive and deductive models of communication, etc. The research is merely a small part of the conversation analyses on live broadcast hotline programs, which is still awaiting much further exploration. |
