动态系统理论视角下的英语专业学生模糊限制语习得过程研究

发布时间：2021-10-21 08:47

　　作为一种重要的语言现象,模糊限制语具有灵活、独特的语义和多种语用功能。因此,无论是在口语还是书面语中,模糊限制语总是发挥着重要的作用。然而,对于二语学习者而言,正确恰当地使用模糊限制语仍是一件困难的事情。目前,国内外关于二语学习者模糊限制语的研究主要集中在模糊限制语的习得结果上,对其习得过程的关注较少。Ellis在2014年提出,二语习得的发展已经不再被认为是一个静态的或线性的表征系统,而动态系统理论的提出为解释二语习得过程中语言动态发展的非线性特征以及个体变异等关键问题提供了有效途径。动态系统理论主要探讨系统发展过程中不同成分交互作用所引起的动态变化,它对传统的研究,尤其是静态形式的研究产生了极大影响。运用到二语习得的研究中,动态系统理论将二语习得研究视角从传统的语言本身研究转移到以发展为特征的学习者行为上。鉴于此,本研究在前人研究的基础上,运用动态系统理论,旨在研究中国英语学习者模糊限制语的习得过程。具体而言,本研究选取中国英语专业学生为研究对象,探讨了其模糊限制语习得过程中所具备的特征,主要研究三个问题:（1）在模糊限制语习得过程中,中国英语专业学生在其频次和种类上有何总体发展特...
