摘要
Bley-Vroman(1989,1990,2009)的根本性差异假说(FDH)认为成人外语学习与儿童母语习得有本质差别。本文旨在讨论FDH的基本观点及立论中存在的逻辑问题。分析认为,FDH立论的概念界定不明确,参照标准不统一。FDH否认普遍语法在成人二语习得中的作用,但是有大量证据表明成人二语习得与一语习得没有本质差异,二语最终的造诣与一语没有质的差异,只有量的不同。
The Fundamental Difference Hypothesis （FDH） （ Bley-Vroman, 1989,1990,2009 ） argues that adult foreign language learning is distinguished from child L1 acquisition. This article examines the arguments and concepts underlying FDH and their problems in argumentation, demonstrating their conceptual vagueness and lack of uniformity in criteria. Against FDH which denies the role of Universal Grammar in adult L2 acquisition, there is ample evidence that adult L2 acquisition is not essentially different from L1 acquisition and that the difference between L1 and L2 in its ultimate state is only quantitative, but not qualitative in nature.
