概念功能中的语义级差与体现形式研究

On Semantic Compositional Scale in Ideational Metafunction and the Realizational Forms

本文在韩礼德与马悌森和马丁与罗斯等人对概念功能的语义组合级差的描写基础上对语义级差中三个层级进行了较为全面的研究,对各个级差成分的意义、类型和词汇语法体现形式进行了至下而上的梳理.研究表明,语义级差是一个由不同语义单位构成的语义复杂度,它以不同的语义单位的组合与再组合形成三个层级,来描述语篇元功能的语义层级.概念功能中的三级是：成分、言辞/言辞序列和事件模式.它们的体现形式分别是词组、小句/小句复合体和小句群。

On the foundation of the description of the semantic compositional scale in ideational metafunction made by Halliday ＆ Matthiessen and Martin ＆ Rose, this paper explores comprehensively the three semantic levels in the ideational metafunction. The study includes the definition, types and the lexicogrammatical realizations of each level. The findings indicate that the semantic scale shows the degree of complexity produced by the compositions of semantic units. The repeated composition results in three semantic levels,which describes the levels in discoursal metafunctions. There are three levels in the ideational metafunction：element, figure/sequence and episodic pattern. Their corresponding lexicogranmmatical realizations are groups, clauses/clause complexes and groups of clauses.
