SLA口语问题与语言障碍对比研究

论文摘要

第二语言习得中的哑巴英语问题一直困扰着中国的英语学习者。很多学习者虽然可以在笔试中取得优异的成绩,但其口语表达中却充满了发音不准确、表达不流畅、及各种各样的语法和用词错误。由于学科间的界限,二语者的口语表达问题被单纯的归因为教学方法和学习方法。本文采取了新的视角,将语言学与语言病理学相结合构建了新的理论框架,通过观察对比,提出了二语习得中的口语问题实为语言障碍的假说。并将试验与问卷相结合,将二语口语中出现的发音错误、表达不流畅、及语言错误与以英语为母语的语病症状加以对比,依据语病诊疗理论对其进行评估。实验结果显示,二语口语问题与语言障碍的症状在构音、口吃和失语症方面分别为完全匹配、部分匹配、部分匹配。通过参照语病诊疗理论及对问卷结果加以分析,排除二语者机体障碍的因素,从而验证了上述发音错误和表达不流畅的问题实为功能性语言障碍(构音障碍、口吃等)的假说,并进一步从病理学角度与语言学角度分析了其成因,找到了解决二语学习者口语问题的新途径。因为母语失语症均由脑病或脑外伤造成,功能性失语的病例极为少见,所以本文只能将二语学习者口语表达中的语法和用词错误等语言现象视为语言障碍而不能将其定义为功能性失语症,语言病理学的进一步发展和对二语习得者的进一步观察将能更好地解决哑巴英语问题。本研究结果对英语课堂教学有一定的启示,为改善二语口语问题提供了新思路。
