语篇的周期性研究

Analysis of Periodicity in Texts

作为系统功能语言学语篇元功能的组成部分和体现语篇意义的语言资源,周期性由主位/新信息、超级主位/新信息和宏观主位/新信息构成。对语篇的周期性研究发现叙述和阐述体裁都利用周期性等语篇意义资源将语篇组织成连贯的体裁结构。研究发现语篇中有标记主位标示体裁阶段或语阶的作用,同时验证了超级主位和宏观主位预示语篇内容,超级新信息和宏观新信息概括和提炼语篇内容的功能。

As component of SFL textual metafunction and language resources to instantiate textual meaning, periodicity consists of Theme/New, hyperTheme/hyperNew, macroTheme/macroNew. Analysis of periodicity in texts shows that both recount and exposition make use of textual resources such as periodicity to scaffold texts into coherent generic structures. It is found the functions of the marked Themes in signaling generic stages or steps, hyperTheme and hyperNew in predicting information, as well as hyperNew and macroNew in summarizing and distilling information.
