从功能语法发展史看系统功能语言学的功能语义导向

功能语法是系统功能语言学的核心组成部分，以功能为基础、以意义为导向是功能语法理论构建的一大特点，也是系统功能语言学理论具有广泛适用性的重要原因。Halliday的功能语法融汇了布拉格学派的语言功能观和伦敦学派的意义观，在理论构建过程中不断向意义推进。语言功能的探索是意义研究的必要前提，社会意义学建立了语言与语境之间的理论联系，使得成熟阶段的功能语法理论呈现出明显的功能语义导向，更全面地反映出人类语言作为社会意义系统的生态特征。 

The Functional Semantic Orientation of Systemic Functional Linguistics: Viewed from the History of Functional Grammar

Functional Grammar is the essential component of Systematic Functional Linguistics (SFL). Functional Grammar has been growing in a functional-based and meaning-oriented fashion, which endows SFL with great potential in the wide-ranged application. Halliday set out to develop Functional Grammar by combining the functional approach to linguistic study from Prague School and the meaning-oriented view of language from London School, which constantly contributed to its meaning orientation in the theoretical construction hereafter. As a necessary step to building a semantic-oriented grammar theory, the exploration of language functions was in turn facilitated by social semiotics. The latest Functional Grammar is a clear display of the ecological features of human language as a social semiotic system.
