This paper investigates the relationship between lexical richness and EFL expository writing quality and examines the predictability of lexical richness indices to EFL expository writing quality. The Chinese EFL expository writing samples were drawn from Spoken and Written English Corpus of Chinese Learners Version 2.0 (Wen et al., 2008) and the lexical richness of the writing samples was analyzed with Lexical Complexity Analyzer (Ai & Lu, 2010; Lu, 2012).
