A mixed approach of textual analysis and interviews was adopted to examine the citation features of MA theses and the identities Chinese EFL learners constructed through citation selection. It was found that students’ selection of citations reflects their linguistic identity, academic and disciplinary identity, as well as novice identity. Their citation practices project different discursive selves to readers. By adjusting the number and relevance of references, they intend to construct a knowledgeable and credible self. The use of ineffective citations and references not only projects an unfavorable impression on readers but reflects a lack of authorial identity. This study has significant implications for the teaching of academic English and the supervision of thesis writing.展开更多
