The Multi-angle Observation Of "Wei (为)"-Sentence In Modern Chinese

"Wei(为)"-sentence the paper observing is that"wei"- phrase in the sentence which composed with the preposition"wei"and the other words occurres syntax and semantics relations to the centeral word of the predicate, ,and it can be be divided into two types:"NP+wei(为)X+VP"and"wei(为)X+NP+VP". At present there are not many consequents which have the whole"we(i为)"- sentence as research objects.The paper has the whole"wei(为)"- sentence as the observing object under the grammar theory of the three-dimensional and the case as a guide,according to the combination principles of the situations and the significances,the dynamics and statics and the structures and functions ,mainly from the three planes of the syntax,semantics and pragmatics to fully examine"wei(为)"- sentence.The main merning of the paper is composed of the following parts:The introduction mainly introduces the features of"wei (为)"on the pronunciation and the parts of speech,and also its combination ability, definiting the object and scope observed and pointing out the theory and methodology and the corpuses source accorded to in this paper.The first chapter overviews the researching present situation of"wei(为)"- sentence from two aspects.One introduces the researching present situation of the preposition of"wei(为)"itself,the other the questions concerned,and the features after combination with other syntactic components and the influences.Chapter Two discusses the kind of the word"wei(为)".This paper argues that the word"wei(为)"connecting the compositions which have the noun function and the verb function is a preposition. In order to facilitate the inspection,the paper is divided into three sections:the front,the middle and the back,and they are marked section A,weiX and section B.This chapter mainly discusses the type "A + wei X + B "for example, in order to inspect the syntactic features of each section.Chapter Three mainly has a brief review of the development of case grammar, and then analysises the case relations marked by the word"wei(为)"in"wei(为)"- sentence,mainly on the parties case, the replace case, the reasons case and the purposes case.Discussing the connections of the reasons case and the purposes case,analyzing the sentence mode of the core sentence of"wei(为)".Mainly analyzing the simple and basic sentence mode of the first and the second scales of the core sentence of"wei(为)",its complicated sentence mode and also the simple and the first expansion mode of the core sentence of"wei(为)".In the fourth chapter, as a reference of the syntax and the semantics,observing the law of sisappearing and appearing of the word"we(i为)"in the core sentence of"wei(为)",and also the components of the topic and the state title in the structure of the language use, analyzing the three functions of connecting,managing scope and the parallelism in the chapter of"wei(为)"- sentence.The conclusion concludes the paper, points out the shortcomings and the problems to be studied later.
