在最简方案框架下,功能语类及其组成特征性质的不同是语言参数差异的根本所在,第二语言习得就是对目标语功能语类中特征值的重设过程。特征的可解释性在一语习得和二语习得过程中有着不同的表现,对中国英语学习者可解释和不可解释特征的习得实验结果表明,与一语中可解释特征先习得不同,二语中特征的可解释性与可及性并没有必然的关系,“特征失效假说”可以更好地解释这一现象。
In the framework of the Minimalist Program, the differences in the characteristics of the functional categories and their constituent features are fundamental to the differences in language parameters. The second language acquisition is the process of resetting the eigenvalues in the functional categories of the target language. The interpretability of features has different performance in the process of acquisition and second language acquisition. The experimental results of the acquisition of interpretable and unexplainable features of Chinese EFL learners show that, Different, the interpretability and accessibility of L2 features are not necessarily related, and “feature failure hypothesis” can explain this phenomenon better.
