近年来的研究认为主从句线性结构是多种因素互动的结果,其理论依据包括语言加工理论、语用分析、语言象似性。本文重点研究象似性原则在线性结构中的体现,并预设象似性原则是确立时间状语线性语序的潜在作用力。为证明预设成立,本文作者自建《高中英语》语料库,旨在对时间状语的分布进行分析。此研究的结果对高中英语的教学有实践价值。 In recent years, the research suggests that the linear structure of the main clauses is the result of the interaction of many factors. The theoretical basis includes language processing theory, pragmatic analysis and linguistic iconicity. This paper focuses on the manifestation of the iconicity principle in the linear structure and presupposes the iconicity principle as the potential force for establishing the linear order of the temporal adverbial. In order to prove the presupposition, the author builds the “High School English” corpus to analyze the distribution of the time adverbials. The results of this study have practical value for teaching high school English.
