Abstract-As a kind of stylized language expression, formulaic sequences are widely used in different spoken language contexts, but the study of English formulaic sequences has always been a difficulty in college students' oral English learning in China. This paper adopts the computer corpus approach and utilizes its massive storage of formulaic sequences and high-speed data retrieval capabilities to help learners with English formulaic sequence learning. On one hand, learners are able to truly and objectively understand the use of formulaic sequences in English-speaking environment through the computer corpus; on the other hand, learners can improve their memories and increase their formulaic sequence learning efficiency with the help of the structured and regularized and massive amount of use cases of formulaic sequences retrieved by the computer corpus. Finally, in the empirical study, through the comparative analysis of the test group and the control group, this paper proves that the computercorpus-based formulaic sequences have great significance to oral English teaching.
