Based on the previous studies, this paper uses questionnaire to investigate the current situation of College English grammar teaching in English major of Ankang University. The results suggest that both teachers and students have a similar attitude: English grammar is an indispensable part in college English teaching; English grammar should be taught in a context. The statistics from students’ final exam of English grammar course also show that traditional grammar teaching brings no positive influence to English grammar ability of college students. The problems are that the students fail to apply grammatical rules into practical use. Based on Systemic Functional Grammar (SFG), this paper tries to construct a teaching model of college English grammar in intensive reading course, which aims to explain pragmatic function of grammatical form in context.
