Self-repair mentioned in this paper actually refers to self-initiated same-turn self-repair,which comprises a particular set of repair strategies in which trouble source and repairing segments occur in the same turn and the repair is both initiated and performed by the speaker of trouble source. This study aims to study the self-repair behaviour of Chinese EFL learners based on the Spoken English Corpus of Chinese Learners as the observing corpus and the reference corpus SBNC. This study is mainly concerned with use frequency,distributions and structures of the selfrepair on the basis of a clear classification of the self-repair,aiming to find out whether there are significant differences in these three aspects of the self-repair between the Chinese EFL learners and the native speakers. Some implications and applications of the findings are also available for English teaching and learning in China.
