The Study On Structure"V_double+Yu（于）+NP" And Its Variability In Chinese

" yu(于)" is a very active preposition in ancient Chinese, but " yu(于)" has changed a lot,with the development of language in modem Chinese. Taking " yu(于)" of the struc ture " Vdoubie+yu(于)+NF’ as the breakthrough point, study the dropping of it, to seekthe cause of variant and effect of the struc ture " Vdoubie+yu(于)+NF’The first chapteris the introduction part. Introduce the significance of thesis topics, summarize the studies of the former scholars on the structure "Vdoubie+yu(于)+NP" a nd its re le va nt re se a rc he s, the n determine the research ideasand research methodson thisbasis.The second chapteristhe investigation of " yu(于)" in the struc tune " Vdouble+yu(于)+NP". Through the process of grammaticalization, distinguish the typicalpreposition " yu(于)", clitic " yu(于)" and typical affixes " yu(于)"; by the database statistics, shed rank the shedding degree of clitic " yu(于)"; by the word frequency statistics, find the solidification degree of Vdoubie and clitic " yu(于)"The third chapter is the investigation of Vdoubie in the structure " Vdouble+yu(于)+NP". On the basis of the structure types and the se ma ntic c ha ra c te ristic s o f Vdo ubie, sum up the re la tio nship b e tw we n the verb-object structure Vdoubie and the partial structural Vdoubie, and the different semantic features Vdoubie with the dropping of " yu(于)"The fourth chapter is the investigation of NP in the structure " Vdouble+yu(于)+NF’. On the basis of the solidific ation degree of the NP role and its composition structure, prove the prototype of place NPby studying the NP virtual path,find the granting-argument function by studying the NP struc ture, to find the effect on the dropping of yu(于)".The fifth chapteris the dropping of " yu(于)" and its effect in the struc ture " V doubie+yu(于)+NP".Find the cause of the dropping of “yu(于)”, make a reasonable explanation to the mechanism ofcoordination valence of Vdoubleand rationalization and generalizationof “Vi+NP”, make an objective prediction to forming into one word of“Vdoubleyu(于)” and the dropping or shedding of “yu(于)”.The sixth chapter is the conclusion part. Make a summary of themain content in this paper, and show the research value of study andpossible innovation and shortcomings for the subsequent study.
