Abstract
The thesis provides some descriptions of lexical cohesion in English. According to the analysis of Halliday and Hasan, lexical cohesion is one of the cohesion devices in English. Continuity may be established in a text by the choice of words. The thesis will cover three forms of lexical cohesion: repetition, synonym and collocation. Although the cohesion need not depend on identity of reference, it is useful to distinguish whether the reference is identical or not. The aim of the thesis is to give an account of aspects of lexical cohesion, which is based on linguistic theory and also applicable in practice. While in different writings, the frequency of using the lexical item is different. The discussion in the thesis will contribute to the development of lexical cohesion theory. Based on evidence from texts of different writings, it will be useful in application to further text study.
Key words: lexical cohesion; repetition; synonymy；hyponymy; antonym; collocation
摘要
這篇論文描述了英語中的詞彙銜接。根據韓禮德和哈桑的分析，詞彙銜接是語篇銜接的手段之1。它就是指通過選擇單詞來保持語篇的連續性。本文將覆蓋詞彙銜接手段的`3種形式：重複，同義性，搭配。儘管銜接不需要依靠指稱相同，但區分指稱是否1致還是很重要的。本文的目的就是在理論和實踐的基礎上討論詞彙銜接的各方面。然而在不同的文體中，詞彙項目的使用頻率也是不同的。那麼在這篇論文中的討論將有助於詞彙銜接理論的發展。既然它都是以不同文體的語篇爲論據，這將對語篇的進1步研究非常有用。
關鍵詞：詞彙銜接；重複；同義性；上義詞——下義詞；反義詞；搭配
