船舶与海洋工程学科学术语篇中的模糊限制语研究

A Study on Hedges in Academic Discourse of NAOE Majors

本研究通过自建小型研究语料库,参照Hyland(1998)的模糊限制语体系框架,采用定性、定量相结合的研究方法探讨了船舶与海洋工程学科学术语篇中模糊限制语的使用情况及语用功能。研究表明,该学科学术语篇中词汇模糊限制语的使用频率最高,此类模糊限制语的使用能够避免学术观点过于绝对,使实验论述更加严谨,从而提高语篇客观性、可信度及读者接受度;与以往研究不同的是,该学科学术语篇还使用了短语模糊限制语,其频率低于前者,这类模糊限制语能够修饰实验过程表述及研究结果数值的范围,使学术观点的表达既留有余地又周密准确;策略模糊限制语在本语料中使用最少,以往的研究鲜少关注此类模糊限制语,经分析,策略模糊限制语有助于强调研究意义。

Based on the self-built corpora for research,following the framework proposed by Hyland(1998),this study combines the quantitative analysis with qualitative analysis to explore the use features and pragmatic functions of hedges in the academic discourse of NAOE(Naval Architecture and Ocean Engineering)Majors.The study shows that the lexical hedges are the most frequently used in the academic discourse of NAOE Majors.The use of such hedges can avoid absoluteness of academic views,make the experimental discussion more rigorous,and improve the objectivity,credibility,and reader acceptance of the academic discourse.Different from previous studies,the phrasal hedges are also used in the academic discourse of NAOE Majors,the frequency of which is lower than that of lexical hedges.Phrasal hedges can modify the range of experimental expressions and the numerical number of research results,making the expression of academic views cautious and accurate.Strategic hedges are the least used in this study,and previous studies have paid little attention to such hedges.
