| In this paper,we select the effective corpus related to the seven synonyms with the meaning of "kaojin" by using Rost CM6 content mining system and antconc3.5.7 are two language information processing systems to search the typical collocations on the left and right sides of seven synonyms,and to explore the typical collocation characteristics of each synonym.Through the comparison of the theoretical basis of the syntactic plane in the three planes,this paper summarizes the characteristics of seven synonyms as various syntactic components,and analyzes the ability of each word to act as different syntactic components in sentences.At the same time,from the diachronic and synchronic perspectives,this paper analyzes the semantic features of the synonyms of "kaojin",analyzes and sorts out the sememe features of seven synonyms of "kaojin" and the corresponding sememe structure of each word.Through comparison and analysis,it is found that,based on the typical collocation of each word,"qiejin" is mostly an abstract and non-specific concept,"aijin" is often related to people;"kaojin" is a place,object and other specific things,"kaolong" is a code of conduct,organization and higher level water standard,etc.,"bijin" is a time,index,an important place or disaster,crisis,etc.,"linjin" it is related to a certain time node,event or activity,and "jiejin" mostly refers to the development process of things or a certain goal or result.In the typical collocation with adverbs,"qiejin" "kaojin" "jiejin" tendency and degree adverbs collocation,"kaolong" "bijin" "linjin" tendency and time frequency adverbs collocation,"aijin" tendency and expression way adverbs collocation.In terms of syntactic functions,the predicate functions of "aijin" "kaojin" "kaolong","bijin","jiejin" are very strong,and "jiejin" and "linjin" have both predicate and nominal functions,among which the syntactic function of "qiejin" is the most flexible.Semantically,"aijin" "kaojin" "kaolong" and "bijin" focus on the dynamic state of motion to reduce the distance between each other,while "qiejin" "linjin" and "jiejin" focus on the non motion state of the distance between each other.As far as the scope and objects of use are concerned,"jiejin" has the widest scope of application."Qiejin" "linjin" and "jiejin" are mostly used in written language."Bijin" often has a negative meaning tendency in the specific context.Finally,according to the analysis and investigation of the characteristics of "kaojin" synonyms,this paper puts forward some corresponding suggestions on the teaching and dictionary compilation,hoping to provide some reference value for this research. |
