| This article, based on the monosyllabic "Mei(美)"-related adjectives, by discussing the disyllabification of monosyllabic adjective. Combines with specific corpus, fully describes and analyses the synchronic differences, the diachronic evolution process and characteristics of them. To study synchronic differences from the diachronic perspective, on the basis of them, study the process of the disyllabification, as well as the corresponding syntactic and semantic changes caused by it in detail.This article consists of five chapters, summarized as following:Chapter I introduces the research reasons, the research objects, the present situation of the research, the research methods and values.Chapter Ⅱ investigates and analyses the synchronic differences of monosyllabic adjective "Mei(美)"with disyllabic adjective "Mei Li(美丽)", "Mei Yan(美艳)", which is mainly reflected in three aspects, such as syntactic features, semantic features, configuration features. At the same time, the syntactic features can be divided into predication function (as predicate center, being followed by a complement, as a complement, etc.) and non-predication function (as subject, object, attributive). The semantic features can be divided into semantic scope and the selection of argument composition. The configuration differences are mainly reflected in reduplication ability. The factors restricting the reduplication ability mainly are associated with amount of semantics and style, and may involve sound, rhyme.Chapter III discusses the historic development and evolution of monosyllabic adjective "Mei(美)", "Li(丽)","Yan(艳)". Firstly, defines the semantic of three monosyllabic adjective respectively. Secondly, the historic investigation is mainly divided into two periods:the pre-Qin and Han Dynasty, the Wei and Jin Dynasties to Qing Dynasty. Then, in two periods, inspects their syntactic distribution, their independence and their adhesive feature in detail. Moreover, makes the corresponding data sheets, analyzes them comparatively, and draws the relevant conclusions.Chapter IV studies the binding mode and the way of the two disyllabic morphemes of a parallel disyllabic adjective "Mei X(美 X)". On the basis of it, takes the lexicalization of parallel disyllabic adjective "Mei yan (美艳)" as the example, discusses the process of disyllabification of monosyllabic adjective. Moreover, investigates the effects of disyllabification on the kind of monosyllabic adjective "Mei(H)" and the disyllabic adjective "Mei X(美 X)". In the end, try to explain the reasons that cause synchronic differences of "Mei(美)" and "Mei X(美 X)" from the diachronic perspective.Chapter V is the conclusion part. One hand, on the synchronic level, summarizes the syntactic differences and the semantic differences of "Mei(美)" and "Mei Li(美 丽)","Mei Yan(美艳)"。On the other hand, on the diachronic level, concludes the similarities and differences of development of "Mei(美)", "Li(丽)", "Yan(艳)", concludes the disyllabification of the kind monosyllabic adjective of "Mei(美)"and the grammatical changes which it caused, explains the reasons that cause synchronic differences of "Mei(美)" and "Mei X(美 X)" from the diachronic perspective。At last, points out various deficiencies in this article and the direction of improvement in future. |
