The Position Framework Of The Causal Conjunctions “Yīnwéi”“Yóuyú”“Jìrán” Which Belong To The Cause Category And Its Methodology Meaning

This article researches the position framework of the causal conjunctions “Yīnwéi”“Yóuyú”“Jìrán” which belong to the cause category systematically and discusses its methodology meaning by using the theories of semantic grammar, discourse cohesion, cognition and other theories and the ways of substitution analysis, contrastive analysis and data statistics from the levels of semantics, syntax, pragmatics and cognition.This article mainly includes five parts.The first part analyzes the characteristics of the causal conjunctions “Yīnwéi”“Yóuyú”“Jìrán” which belong to the cause category according to three aspects of already, directionality and motivation from the perspective of semantics.The second part investigates the similarities and differences of the causal conjunctions“Yīnwéi”“Yóuyú”“Jìrán” which belong to the cause category on ways of matching, objects of collocation and suitable sentence types and analyzes the complementary distribution of them three from he perspective of syntax.The third part analyzes the sentiment orientations, style differences and cohesion functions of the causal conjunctions “Yīnwéi”“Yóuyú”“Jìrán” which belong to the cause category from the perspective of pragmatics. Among them, We focuses on analyzing the sentiment orientations of“Jìrán” and divides them into declaration, appeal, helplessness and dissatisfaction four types.The fourth part discusses the differences of subjectivity of the causal conjunctions“Yīnwéi”“Yóuyú”“Jìrán” which belong to the cause category and points out that the subjectivity of “Jìrán” is the strongest, “Yīnwéi” second and “Yóuyú” is the weakest from the perspective of cognition.The fifth part discusses the methodology of this study from locating the meanings and functions by framework, finding the similarities and differences by clustering comparison,observing the using rules by double perspectives of in-sentence and out-sentence, testing the reliability of rules by multi-sources corpus comparison, and integrate the integrity of the position framework by absorbing the latest research results, etc.
