| As a media product,TV programs have broad dissemination capabilities and profound social influence.With the development and change of media,the context of radio and television communication has become complicated.As an important part of TV programs,the use of "practical,relevant,appropriate and effective" language by the host in the communicative context plays an increasingly important role in enhancing the communication effect and the program’s influence.Therefore,the language expression of the host in the TV program has great artistic and research value.This thesis focuses on the interactive discourse of the host,guided by the pragmatic theories such as Verschueren’s language adaptation theory,explores the language choices of the host Sa Beining in different programs,and summarizes the function of the host’s interactive discourse in TV programs,and explores the construction strategy of the host’s interactive discourse.The introduction part explains the basis of the topic selection,the significance of the topic selection,the research status,the theoretical basis,the research method,and the use of the corpus.The first chapter summarizes the characteristics of the host’s interactive discourse by analyzing the characteristics of the host and the host’s discourse role,which is a dynamic process of language selection according to different contexts.These discussions provide the basis for the following case studies and theoretical explanations.The second chapter discusses the adaptation of the host’s interactive discourse to the communicative context.The communicative context affects and even restricts the choice of the host’s interactive discourse.In verbal communication,the host achieves a good communication effect by adapting to the communicator,the psychological world,the social world and the physical world.The third chapter discusses the adaptation of the host’s interactive discourse to the language context.The host’s adaptation to the linguistic context is reflected in different levels such as pronunciation,vocabulary,sentences,and discourse.According to the context,the host makes adaptive choices from these language levels to reflect the communicative intention and achieve the communicative purpose.The fourth chapter,on the basis of corpus analysis,with reference to the classification of the three meta-functions and the role of the host,explains the function of the host’s interactive discourse from four different aspects: the function of information transmission,the function of value guidance,the function of interpersonal adjustment,and the function of aesthetic experience,and try to explore the construction strategy of the interactive discourse of TV host.The innovation of this thesis is that,it focuses on the interactive discourse of the host from the perspective of adaptation theory,tries to put forward some new knowledge and understanding for the TV host and the interviewee to conduct verbal communication more effectively.Provide the host with a discourse strategy with practical value,so that it can better achieve benign interactive results in the complex verbal communication activities. |
