文档介绍：论文摘要本文以Halliday的概念功能中的逻辑功能理论和Martin的连接和信息流理论为框架, 以美国总统奥巴马的就职演讲为语料,研究演讲在小句和小句复合体层面和文章组织结构方面所呈现的逻辑联系及其特征,并探索其特点对演讲效果的意义。研究揭示:在演讲中,简单句被广泛虑JH{。在小句复合体中,并列一扩展关系句子的个数超越从属一扩展关系句子的个数;解释关系的句子个数超过扩展和增强关系句子的个数。这一特征体现了演讲稿简单的句式,详尽的解释,强劲的说服力;同时形成了排比,对照, 反复等修辞效果。讲演中内在联系关系个数多于外在联系个数;内在联系中“similar'’和“additive”被广泛应用,前者体现文章中类比,重述,概括,详述写作方式,后者用米表明论据的序列;“consequence”用来表明充分的因果,条件等关系。丰富的逻辑关系更使文章结构紧凑,论据充分,使演讲更具说服力。另外连接的分析和文章“hierarchy”结构紧密联系,如文章第4部分第3层又包含5个小层;从篇章格律角度看,第3层的“hypertheme”表现出对5个小层的“theme”期望关系,这一特征能使听众更好的把握文章的篇章结构和段落特征,同时能更清楚的理解演讲的内容。通过对演讲的试探性的研究分析,希望对政治演讲的写作及理解与欣赏具有一定的指导意义。关键词:逻辑功能,连接关系,篇章格律,政治演讲 Abstract This thesisattempts toanalyze meaning—making ofOba:mi’、inaugural speech under the guidance of Halliday’S logical metafunction l}lc,1‘yand Martin,s conjunction and periodicity theory Itaims toreveal thelogical∽h tons ofthespeech atthesemantic level and italsoaims toinvestigate how :he textcontribute to apowerful speech.
