In English writing classes, some college students' writing expressions are not authentic, logic is not coherent, and the content lacks something new. Based on the two functions of metaphor: rhetorical and textual, this paper discusses the application of metaphor thinking in college English writing class in order to enrich students' writing expressions and help them to construct coherent essays.Through lectures of metaphor knowledge in class, case analysis, creative writing exercises and reading activities in and out of classroom, the research results show that integrating the teaching of conceptual metaphor into English writing class not only can enable students to have a systematic understanding of metaphor and raise their awareness of it but also can make students think more actively to overcome such problems as writing in a boring and logically chaotic way. Meanwhile, it has increased the students' interest in writing and promoted the quality of English essays to some extent.
