线性语法结构中的一个句子成分与另一个句子成分发生语义关系时,其语义指向常常不是后者的语义结构整体,而是这一结构中的某个义素。义素结构层面语义指向分析有助于揭示词汇语义变体产生的机制、体貌意义的表达机制、句子成分与语义配价的错综关系,是解释同类语词语法差异原因和深入进行语言对比的有效手段。 When a sentence component in a linear grammatical structure has a semantic relationship with another sentence component, its semantic orientation is often not the semantic structure of the latter as a whole, but a certain sememe in the structure. Semantic analysis of semantic structure helps to reveal the mechanism of lexical semantic variation, the mechanism of expression of physical meaning, the intricate relationship between sentence components and semantic valences, which is an effective way to explain the reason of grammatical differences of similar words and to make further linguistic comparisons .
