Recently in humanities research, the ”Authentic Materials” approach has become increasingly important. Especially it's widely used in language study or language teaching. According to K. Goodman (1986), a language learning expecting the designed objectives must create a real, natural, meaningful, reasonable, interesting, based-on the students' experience environment. This approach consists with these above conditions, and be often important by virtue of the activities of second language teaching and learning.In fact, this approach is not only suitable for second language learning, and also applies to first language teaching. However, caused by stress too much the written language and ignoring the spoken language, the students are lack of oral grammar concept, generally inadequate on their spoken understanding. Furthermore, the materials of teaching grammar can be founded everywhere in daily life, such as the title of the journal and magazines, the text of advertisements, pop lyrics words, or even the funny jokes, etc., these seem very ordinary but existing wonderful meaning simultaneously, could also the media role for accepting students into the advantage environment. For waking up the students' sense, we designed a series of courses with the Authentic Materials approach, and encouraged students to participate in excavations their live corpus. After the preparation, the following class became more reactive and effective.In order to prove the effect, I have designed a questionnaire to my students of grammar lesson class as object, and taken a series of survey to realize their satisfaction. Further, we made the explication of authentic materials in many aspects. We could not only provide teaching models to students, and also guide students to dig more resources from the life reality, and to explore the uniqueness of grammar teaching in Mandarin.
