讨论了语篇中主位推进的模式与信息呈现的形式 ,虽然主位推进的模式复杂且多变 ,但各句首成分表达已知信息 ,述位表达新信息 ,语篇不断地由已知到未知 ,从而形成一个将未知化为已知 ,再由已知到达另一未知的话语链 ,从而整个语篇所表达的信息呈现“已知 -未知-已知 -未知 -已知”的形式。这种信息传递方式符合我们组织信息和理解信息的脑机制 ,对于理解语篇有深远的意义。
Discusses the thematic progression of discourse and the form of information presentation. Although the mode of thematic progression is complex and changeable, the first component of each sentence expresses the known information and the new position expresses new information. The discourse is continually replaced by the known To unknown so as to form a chain of unknown words as known and then known to reach another unknown discourse so that the information expressed throughout the discourse takes the form of “known-unknown-known-unknown-known” . This means of communication is in line with our brain mechanisms for organizing information and understanding information and has far-reaching meanings for understanding discourse.
