【摘要】 源于语篇分析在语言学研究的蓬勃发展及取得了可观的成果，语篇分析已受到国际语言学界的高度重视。与此同时，反映语篇结构成分之间关系的衔接理论，在现代语言学中亦引起了普遍兴趣。衔接理论是系统功能语言学的一个重要组成部分。谈及衔接理论，目前人们既有一致看法也有很多分歧。总的来说，由于语言学家研究语篇的角度不同，他们对衔接的定义也不一样。在这篇论文中，作者介绍了一些语言学家对衔接理论的阐述及其分类，主要运用韩礼德的衔接理论框架，试图将此理论应用。 本文的研究对象是美国总统就职演说词。众所周知，美国总统就职演说词属于典型的政治语篇，衔接理论又是语篇分析的一个重要的课题，因此，为了能进一步研究衔接的特点，本文作者从衔接理论的五个方面来研究美国总统就职演说词。这五个方面包括指称，替代和省略，连接，词汇衔接。 通过大量实例分析，论证了韩礼德的衔接理论在这种典型的政治语篇中是怎样得以实现的。与此同时，作者发现，在不同时期子语料中，对于衔接的运用有相似之处。通过对比，作者亦发现衔接的使用在美国总统就职演说词和网络会话中有一些不同之处。这对于作者来说是一次挑战。希望通过对此理论的研究，不仅可以帮助我们成为更好的公众听众，并且可以帮助我们最大限度的理解演说词的内容。更多还原

【Abstract】 Discourse analysis has become a flourishing development of linguistic study and gained considerable achievements. Consequently, it has received the international linguistic circles’ high attention. At the same time, cohesion theory which can reflect the connection between the structural components of discourse arouses the common interest in modern linguistics.Cohesion theory is an important component of systemic functional linguistics. When speaking of cohesion theory, linguists hold identical and divergent viewpoints on it. Generally speaking, linguists study discourse from different angles. Accordingly they define cohesion in different ways. In this thesis, the author introduces some linguists’ expounds of cohesion including its classifications. Then, Halliday’s cohesion theoretical framework is applied into practice.The object of my project is the U. S. selected presidential inaugural addresses. It is well known that the U. S. selected presidential inaugural addresses are typical politics discourse. Cohesion is one of the most important objects of study in discourse analysis. Therefore, to make further study on cohesion features, the writer carries out an investigation based on the selected materials from five devices of cohesion: reference, ellipsis, substitution, conjunction and lexical cohesion.The thesis demonstrates how Halliday’s theory of cohesion generally realizes in the typical politics discourse with a great number of analyses. At the same time, in different periods of sub-corpora, many similarities of cohesion devices have been perceived by the author. And by comparing, the author also finds that there are some differences of cohesion devices in the U. S. selected presidential inaugural addresses and the conversations on IRC. It is a challenge to the author. We hope that it can not only make us become a good public listener, but also better help us to understand the effective communication largely depends on cohesion function.更多还原
