【摘要】 以动态系统理论为视角，结合中介语对比分析法，探究中国英语专业学习者议论文语篇中模糊限制语的使用情况。研究中选取《中国学生英语口笔语语料库》(2.0版)中的议论文语料和鲁汶英语本族语议论文语料，并根据程度变动型、范围变动型、直接缓和型和间接缓和型对模糊限制语进行分类，对不同水平学习者的模糊限制语输出进行分析。研究发现，中国英语专业学生议论文中模糊限制语的使用存在少用、滥用和类型单一的问题；模糊限制语的习得过程呈现非直线型上升；高水平学习者在某些词语使用方面更接近本族语者。更多还原

【Abstract】 From the perspective of dynamic system theory and interlanguage contrastive analysis, this study explores the use of hedges in argumentative writings by Chinese EFL learners.Argumentative essays are randomly picked out from the SWECCL(version 2.0) and LOCNESS corpus.The four most commonly used types of hedges, including adaptors, rounders, plausibility shields and attribution shields, are selected to analyze the output of hedges of learners at different proficiency levels.The research has found that hedges are rarely used or abused in argumentative writings by Chinese EFL learners who tend to use a single type of hedge.The acquisition of hedges is not a linear process.Advanced learners are more similar to native speakers in the use of certain hedges.更多还原
