复杂述位

本文以语言的符号性为基点，以英语和汉语的丰富实例为依据，论证小句主述结构的述位可以是一个复杂的内嵌次主述结构，确定了复杂述位存在的重要意义，从而使系统功能模式和认知层次模式的主述结构部分，能通过（内嵌）主述结构、（次）主位，比较全面地指出主述结构和表义结构的不同重合方式以及与此相应的不同句式。

Complex Rheme

This present study is conducted within a semiotic framework, within which I argue that a rheme can be an embedded structure,which consists of a sub-theme and a subrheme. This rheme is termed bete as a″complex rheme″.With strong evidence from both English and Chinese provided, this paper explicitly demonstrates the semiotic significance of this new statement that the establishment of the complex rheme captures the content-expression sameness and differences between themes and sub-themes.
