目前学界对于二语形态可变性形成机理的解释还没有达成共识,围绕特征在习得中的重要作用数种假说相继而出,其中“特征重组假说”成为目前学界格外关切的对象。本文以特征理论为基础,探讨了特征重组与参数设置对二语习得的解释力。 At present, no consensus has been reached on the explanation of the formation mechanism of the second language morphology variability in the academic circles, and several hypotheses have been successively developed around the important role of the feature in the acquisition. Among them, the “feature recombination hypothesis” has become the object of special concern to the current academic circles. Based on the feature theory, this dissertation explores the explanatory power of second language acquisition through feature recombination and parameter setting.
