一、引言中介语研究重点探寻二语学习者语言学习的共性,解释二语习得的发展路径。可是虽然在词汇、从句习得过程中呈现出很多规律性特征,不论在起点、学习过程还是最终学习结果方面,学习者之间差异相当大,这是什么原因呢?研究者认为这是由于学习者个体差异因素造成的,个体差异研究弥补了中介语的研究缺陷,加深了人们对二语习得领域的认识。 I. INTRODUCTION Interlanguage studies focus on the commonalities of second language learners’ language learning and explain the development of second language acquisition. However, although there are many regular features in the process of lexical and clause-based acquisition, what are the differences between learners in terms of starting point, learning process and final learning result? The researchers think this is due to learning Individual differences caused by the individual differences in research make up for the study of interlanguage defects and deepen people’s understanding of the field of second language acquisition.
