Abstract This thesis is a corpus-based discourse analysis of the open culture courses of Yale University, the world-class university, in native English。 This study is to use the corpus analytical software AntConc3。4。3w to analyze a self-established corpus through quantitative and qualitative methods。 87061

Through extracting the small words, observing the high frequency, analyzing the clusters of the key words as well as studying the discourse management chunks, this research explains the key words from the corpus and explores the meaning in the texts。 Furthermore, it reveals and verifies the three core features of cohesion and coherence, contextual features and interaction in the discourse analysis。 This research is hoped to provide inspirations for discourse analysis researches and college English teaching and bilingual teaching nationwide。

基于语料库的耶鲁大学文化开放课程教师话语分析研究

摘要本论文基于语料库，对以英语为母语的世界一流大学——耶鲁大学文化开放课的文本进行话语分析。此次研究采用定量和定性的方法，利用语料库文本分析软件AntConc3。4。3w，对自建语料库进行分析。

通过提取口语小品词，观察高频词，分析关键词的搭配,以及研究口语互动词块，进而解释一些从语料库中提取的重要单词并且发掘在文中的意义。进而揭示并试图验证在话语研究中考察话语的三个核心特征——衔接与连贯、语境特征和互动性。希望本次研究对国内大学英语教学以及双语教学的话语分析研究与应用也会有所启发。
