英语报纸新闻与社论主位结构的比较

A corpus-based comparative study of thematic structures of English newspaper news and editorials

以Halliday的主位述位理论为依据,尝试使用语料库语言学方法研究英语报纸新闻与社论的主位结构特点。建立了英语新闻语料库和社论语料库并对两个库的文本做了词性附码,然后,分类统计出两个语料库中不同类型的主位结构的总数并对得出的数据做定性分析。此外,还抽样统计和分析了新闻与社论中陈述事实小句和表达观点小句的不同主位特点。为语料库语言学方法在功能语言学研究中的应用做了一次有益的尝试。

On the basis of Halliday＇s theme-rheme theory, this paper presents a corpus-based comparative study of characteristics of different theme structures in English newspapers and editorials. Firstly, the English news corpus and editorial corpus are compiled and POS-tagged, and secondly the POS-tagged texts are further processed so that different types of theme structure can be counted and classified. Then the results are analyzed qualitatively. In addition, sample news texts and editorials are taken from the two corpora and used for analysis of characteristics of different themes either in the clauses stating facts or in the clauses expressing opinions. This research is a new attempt in applying corpus linguistics approach to the study of functional linguistics.
