Research On Discourse Structure Based On Intertextuality Theory And Its Enlightenment To Teaching

With the help of intertextuality theory and the principle of combining forms and meanings,this paper studies the structure of Chinese texts,focusing on analyzing how intertextual texts in different time and space domains enter the current text and how does the current text achieve the context and interoperability of its own discourse in different positions.And based on existing knowledge,they are classified into two types: embedded discourse-related intertext and regulated discourse-related intertext.The article sorts out the expression forms of these two intertextual types,divides the embedded intertextuals into four types of discourse embedding types:holistic,characteristic,semantic and usage,and also divides the regulated self-intertexts into four types: referentials,quotation,marked and structural.The study found that embedded intertexture can influence the text structure by participating in the construction of the current text sentence,serving as the main structure of the current text,and simplifying the bearing structure of the text semantics.It serves to make the discourse structure dual-vocal,intervene in the interaction between the author and readers,introduce explanations and examples,and guide the readers in psychological association.The reason why regulated self-intertextuality can be achieved lies in the non-linearity of the text structure.It has a different implementation mechanism and internal structural characteristics from embedded intertextuality.It can help create a sense of presence in the regulated discourse and deal with the temporary factors of the textual scene,explicit clues to the development of the text,reflection on the development of the text,etc.In addition,from the perspective of intertextuality,combined with the conclusions of discourse structure analysis,we summarize the enlightenment of this study in the teaching of Chinese as a foreign language.
