英语学术语篇中投射动词时态的语法隐喻

An Approach to the Metaphorical Meanings of the Tense of Projecting Verbs in English Academic Discourse

学术语篇中的投射语言已受到越来越多研究者的关注,因为在学术语篇中出现频繁的投射语言是实现学术语篇概念的准确性、判断的严密性、推理的周密性等特点的主要手段。但英语学术语篇中的投射动词时态运作机制还未引起足够的重视。实际上投射语言在很多情况下需要借助投射动词时态的语法隐喻来建构,以实现其特定的人际意义与语篇意义。基于目前的一些理论不能恰当、充分地分析与解释投射动词时态的功能作用,文章运用系统功能语言学的语法隐喻理论和功能时态理论,探讨了英语学术语篇中投射动词的时态隐喻功能意义。

The paper, based on the theory of grammatical metaphor and tense system in Systemic Functional Grammar （SFG）, explores a particular aspect of academic discourse： the English tense of projecting verbs, which is an essential feature of academic discourse. However, the function of the tense of projecting verbs has not been fully explored and explained. By applying the principles of grammatical metaphor in SFG to the analysis of the tense of projecting verbs in the English academic discourse, we find that grammatical metaphor can help to provide further explanations as to what types of projecting verb tenses are used to achieve certain effect in academic discourse. Finally, from the discussion and the analysis, this research concludes that grammatical metaphor plays an important role in constructing the deeper, complicated metaphorical meanings and functions of the tense of projecting verbs in academic discourse.
