基于信度分析的英语论辩语篇言据性对比研究

A credibility-based study of evidentiality in English argumentative discourse

本文在言据性研究框架下,选取论辩语篇中的重要类型学术语篇作为研究语料,对比分析国外期刊论文作者、国内期刊论文作者和本科学生三类作者在撰写英语学术语篇过程中构建语篇观点信度的模式差异和发展特点。研究表明:1)三类作者的证素语用策略总体相似,但在证素总量、类型、语言表现形式等方面存在较大差异,尤其是指标性证素有不同的使用倾向;2)证素语用策略与作者的语言习得、学术经验成正相关;3)基于言据性的论辩语篇写作教学将有助于培养学习者的学术写作规范意识。

In the framework of evidentiality, this paper compares English academic articles of foreign and domestic authors and undergraduates to investigate their relevant evidential strategies and patterns of building the credibility of arguments. Results show that three types of authors adopted similar evidential strategies on the whole, but differed in terms of frequency, type and linguistic representation of evidentials, especially the use of index evidentials. This leads to the conclusion that the application of evidential strategies has positive correlation with authors language acquisition and research experience, and hence evidentiality-based writing teaching will help raise English learnersawareness of academic writing norms.
