Research On Logical Structure Markers In Different Registers

Syntactic structures could be classified into two types:the syntax structure in narrow sense and the logical structure.The logical structures are often realized by encyclopedic knowledge,ellipsis and correlatives to illustrate the logical relationships which including coordinate,contrast,continuous,selection,progressive,concessions,causal,hypothesis,purpose,condition and so on.The logical relationship between the logical structure markers,the marked degree and marked pattern are critical for discourse,the logical structure markers are highly correlated with discourse,so the logical structure markers also display different distributions in different registers.Therefore exploring the difference distribution is of great significance to understand the language system.The current research takes the logical structure and the respective marking way in each registers as the research object,based on a variety of registers of corpus sources in Mandarin,the research tries to analyze the differentiation mechanism of logical structures.The logical structure markers could be classified into two sub-types,one is the pure associated marking word which includes the sentence conjunctions,relevance between adverbs;the left are discourse markers which still with the logical meaning.The logical relationship between complex sentences varies with registers,the logical structure markers are the most direct embodiment of register variation,and the marked degree of logical structure and the marked pattern play important roles in shaping the different registers,and reflect the diversity of register differentiation.This thesis consists of seven chapters:The first chapter is the introduction part,mainly expounded the logical structure markers from the perspective of register research,as well the significance and theoretic value.The chapter also summarized the important researches in syntax and the researches on logical structure markers,then introduced the main registers the research to be involved.The second chapter discussed the marked development of logical structure markers.The grammaticalization of individual logical structure markers and the formation of double logical structure markers were analyzed in this chapter.The research found that the grammaticalization and re-grammaticalization process of logical structure markers are much more active in colloquial situations,but the activity is relatively slow in registers of scientific style,the situation in official document writing are similar.The third chapter discussed on the marking pattern of logical structure marker,including the appearance/disappearance of markers,the length of markers,multiplication use of markers,the pause function of markers,the expansion of markers of same category,etc.The research found that the marking patterns in oral and some art registers tend to be in the form of ellipsis,deflation and compression.The marking pattern of scientific register has a big difference with spoken language and artistic style,the logical structure markers in scientific registers are more inclined to utilize complete forms.The fourth chapter focused on the marked degree,the density and marking depth of logical structure markers in different registers,while it is actually the study on grammaticalization from the quantitative perspective.In terms of density of logical structure markers,the natural dialogue register enjoys a low marker density,significantly lower than political register,the scientific and technology register.On the logic depth part,that in the scientific register showed a deeper level.The fifth chapter took the registers as the mainline,based on the contents in Chapter two to Chapter four,the feature system of logical structure makers was established,then probed into the formation of the main registers.The sixth chapter re-examined the main factors influencing the differentiation of logical structure markers in different registers,and further inquired the various style factors behind the various restricting factors mentioned.The Chapter seven summarized the main conclusions,innovation and deficiency of the thesis.
