A Study On Thematic Structure Of Spoken Uyghur Language

Most of the studies on the grammatical structure of Uyghur language adopt the "subject-predicate" framework of traditional grammar to explain relevant phenomena,and pay less attention to the oral grammar,and even less to the study of Uyghur language under the theoretical framework of systemic functional linguistics.This paper uses the theory of thematic structure in Systemic Functional Linguistics to describe and analyze the structure,classification and characteristics of "theme-rheme"in modern Uyghur language.At the same time,based on the function of language to transmit information,this paper carries an in-depth study on the information structure,characteristics and information flow of Uyghur spoken language,and on this basis summarizes the thematic structure advancing mode in Uyghur spoken language.This paper analyzes an spoken Uyghur corpus of more than 2500 sentences,of which 1843 are valid corpus,681 are "theme-reme"structure,and 140 are thematic structure propulsion model,including radial propulsion model,aggregative propulsion model,stepped propulsion model,and cross propulsion model.In Uyghur oral communication,theme is generally the starting point of the discourse content,which is familiar to both the speaker and the receiver.The theme represents the known information,and normally is located in the beginning of a sentence.However,there are also situations in which it is located at the end of a sentence,which is related to the word order of the discourse.Rheme is basically a narrative on the theme,and is the main discourse that developed from the theme.It is the information that the speaker wants to deliver to the receiver.Generally,general discourse is the core of the communication and also the new information,which is located in the end,sometimes it also can appear in the beginning,this kind of circumstance also is related to the word order.In addition,according to the theory of thematic structure and the analysis of actual spoken language corpus,the themes in modern Uyghur spoken language can be divided into two categories:single theme and complex theme,marked theme and unmarked theme.Through the analysis of modem Uyghur language oral communication,it is found that the expected speaker's speaking habits,etc.,can cause a change in word order.In addition,it can also cause omission in Thematic structure.To be more precise,even if the discourse is extremely clear,Theme ellipsis orRheme ellipsis still occur.In the spoken Uyghur corpus,43 of them omitted Theme,and Rheme omission is relatively rare.According to the analysis of corpus,in Uyghur oral communication,this kind of thematic ellipsis occurs more frequently in the dialogue style.In addition to what has been said above,there will be multiple themes and multiple rhemes in discourse communication with a longer discourse content.This situation reflects the information flow in oral communication according to the changes and connections between themes and rhemes,rhemes and rhemes,and rhemes and rhemes.At the same time,it expresses the complete thought and communicative meaning that the speaker wants to express during communication.This kind of change and connection is the thematic structure advance mode.Based on the analysis of actual corpus,there are four modes of thematic progression in Uyghur spoken language,namely radial,convergent,stepped and crossed.
