This is a corpus-based research focusing on the high-frequency verb "keep" used by Chinese non-English majors and native speakers. The corpora involved in the paper are Brown which stands for native speakers, Students 3 and Students 4 in CLEC (Chinese Learner English Corpus) which stand for Chinese non-English majors. The paper tries to investigate the similarities and differences between them and put forward the possible reasons. At last, some suggestions of ELT (English Language Teaching) are given.
