The present study aims to investigate the relationship between missing articles and the impairment of interlanguage syntax within the theoretical framework of the Minimalist Program by examining the written production data from Chinese Learner English Corpus (CLEC). The results show that Chinese learners of English omit some articles, but the functional category D is present in their English, very little article substitution is found and the Definiteness Restriction in there-insertion is also observed. Such findings imply that Chinese learners of English distinguish definiteness from indefiniteness, the feature of definiteness is specified, and Chinese learners’ English syntactic system is not impaired.
