(a) English grammar teaching content
From the content point of view, grammar teaching content should include three aspects: language structure (including morphemes, voice, sound form and syntactic form, etc.), semantics and pragmatics. Grammar teaching is not only to enable students to master language form and meaning, to make more students know the use of forms, grammar with communicative meaning. Therefore, from this perspective, the high school English grammar teaching is not so much to teach students knowledge, cultivate the students' grammar consciousness rather.
From the perspective of the process of learning grammar, grammar learning process has two forms, one is dominant, the other is recessive. So what is the dominant learning style can help to master grammar, or implicit learning helps to master the grammar? Lightbown research even found that dominant teaching has hindered the development of students' language ability. Therefore, generally believes that the best way to English grammar teaching is the union of dominant and recessive teaching; Declarative syntax is imparting knowledge, but also through a variety of communicative activities using grammar, programmed to promote the acquisition of grammar knowledge, cultivating students' comprehensive ability of using language.
(2) the role and status of the English grammar
1. English grammar and English language
About English grammar and English language, the relationship between ZhangZhenBang believes that language is a tool of social communication, is the significance of vocabulary and grammar system. From the point of view of constructivism, grammar is the organization law of language, it gives the structure of language system, and the vocabulary is the building material, it is through grammar and language meaning content.

English language knowledge (grammar), therefore, plays an crucial role in English language learning. Especially for like this to learn English as a foreign language in China, because of the lack of the corresponding English language environment, want to master English language acquisition is difficult to do. Therefore, English language knowledge (English grammar) learning is very important to a certain extent. In addition, we should also understand, English grammar learning is not, and can not be the ultimate goal of high school English classroom teaching. Comprehensive grammar learning is learners use the language ability and organic part of the basis of the purpose is to through the grasp of the language structure system, which is accurate, skilled use of the language services. But for a long time, how to ensure that learners comprehensive, system, effective to master English grammar and skillfully use so as to achieve the aim of pragmatics, it is a long-term problem. For this, this paper proposes the grammar teaching of PWP model in order to help learners to learn English language knowledge.
