论文的第一章是一个简单的介绍，涉及到本文研究的目的和意义，同时本文的大体布局有所规划，根据介绍，读者对本文可能会产生一个基本的印象。变形一词本出自于希腊语，而形态学则是语言学的一个分支，尤其是形态学中的词汇学，它研究词的内部结构和规则，比如有一词多义，这也是属于形态学中语法的一个分支，它侧重于对结构和形式的研究，形态学的本质则是构词法。自从1970年代以来，西方的形态学已经开始注重单词的音调变化和衍生品,因为印欧语系大大促进了语法和词汇的发展。因此,形态学分为两个领域:屈折形态学和派生形态学,而且很显然，后者着重研究词汇。派生形态学在词汇学中主要集中在构词的过程，语言学家认为考虑语素或词为基本单位的形态学是从索绪尔的《结构语言学》发展而来的。

CHAPTER ONE INTRODUCTION

This is the first chapter of the thesis and it will be a brief introduction to the paper. The purpose and significance of this paper will be introduced. At the same time, the layout of this paper will be listed. According to the introduction, the reader could have a basic impression of this thesis.

1. 1 Introduction of the paper

The domain of morphology is from the Greek word, morph. Morphology is one of the branches of linguistics, especially the lexicology, which studies the internal structure and the rules of words, such as those having more than one meaningful element, and morphology is also the branches of grammar, but it focuses on the structure/ forms and kinds of the words. The essence of morphology is word-formation.

From the 1970s, Western morphologists have begun to lay stress on the inflection and derivatives of words because the Indo-European contributed greatly to the on grammar and vocabulary. Thus, two domains are divided: inflectional morphology and derivational morphology, and obviously the latter focus on lexicons. Derivational morphology is focussed on the process of word-formation in lexicology.

Linguists have considered consider morpheme, or word as the basic unit of morphology since the structural linguistics of Saussure. Morphological structure can be interpreted as the concatenation of morphemes. Morphemes and morphs are the results of research of the same language basic unit starts from lexical morphology and derivational morphology respectively.

However, the generativists believe that, if grammatical morphemes are located in the lexicon like words, then the rules will bind them as compound words. Generativists analyze words in the domain of morphology, while sentences in syntax. Generational morphology designs a morpheme based model: build a corpus, a series of morphemes operated under a set of word-formation rules, and the word-formation rules are morphological rules. Thus, morphology is actually the binding of syntax on one end and semantics on the other end. Among these, corpus is undoubtedly the frame of language study, deduction and elaboration.

Just as society develops, the developing of the society, words are change in form, pronunciation and so on. In the process, some words were never seen appear while some disappear. Based on this phenomenon, a conception of productivity emerged. Productivity is one of the key concepts of derivational morphology. It refers to the ability to construct new words of affixes or word-building rules. Productivity is 'used in linguistic to refer to the creative capacity of language users to produce and indefinitely large number of sentences.'(Crystal, 1991, p.279). Hockett (1985, p.575) gives the label productivity to that property of language which al本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
