本文从认知角度解析词语跨体使用的深层原因。以影响词语跨体使用的四个维度为基本参数,即:范畴成员的相似度、语体表达空位度、侧面特征的凸显度、语境的提示度,试图与认知语言学结合,对跨体现象展开科学的量化分析,并探讨量度改变时表达的效度问题。最后得出结论,指出四个维度和词语跨体使用的量度和效度之间的对应关系。 This article analyzes the deep reasons for the cross-body use of words from a cognitive perspective. The four dimensions that affect the use of words across the body as the basic parameters, namely: the similarity of the category members, the level of expression space, the prominent features of the side features, the prompt degree of context, trying to combine with cognitive linguistics, cross It manifests itself as a scientific quantitative analysis and discusses the validity of the expression when the measure is changed. Finally, the conclusion is reached, pointing out the correspondence between the measure and the validity of the four dimensions and the use of words across the body.
