【正文】 Teachers can make them aware of the proper usage of the language. Teaching grammar in context would be an effective way to link grammatical knowledge with language use in actual situation. Therefore, the learning process bees more effective than the traditional approach. More importantly, it provides a natural context for students to learn and practice the forms and functions of grammatical structures. Presenting the grammar points to be learned in an interesting wayOne way to present the structures of the language effectively is to tell an interesting story. The story should contain the new words and expressions that the teacher is going to teach and it should not be too plicated so that everyone can get a general idea of it. It would be better if the story is related to the text to be learned in some way. While listening to the story attentively, the learners will encounter these new words and expressions and they will be eager to know the meanings and usages of them so that they can understand the story better. Another way to achieve the same goal is to elicit by asking questions. The teacher may design some questions beforehand that are close to the learner’s real life which must be answered by using the new grammatical knowledge. For example, in order to teach direct speech and indirect speech, the teacher may first ask one of the learners, “Do you like playing basketball?” The learner may answer, “Yes, I like playing basketball.” Then the teacher can ask the whole class, “What did he say?” After leaving a few seconds for them to think, the teacher may answer by himself, “He said he liked playing basketball.” This kind of cooperation between the teacher and the learners seems natural and effective. It also provides the learners with a context of using the language in real life. Teaching grammar in practiceAs we know, when we use Communicative Approach to teach grammar and grasp the grammar in practice, we usually accept several types of practice. First of all, we accept meaningful practice. In meaningful practice, the focus is on the production, prehension or exchange of meaning though the students pay attention to the way in which newly learned grammatical structures are used. Meaningful practice usually es after mechanical practice. For example, after the presentation and mechanical practice of adjective parative and superlatives, the following activities can be done as meaningful practice.Look at the item below. Rank the item on the left column according to the criteria listed on the top. When I came to teach the students t。 Grammar can help them master the language better, and lay a solid foundation for better munication. We can say the relationship between grammar and munication is plementary. And the teaching of grammar will be greatly improved in the municative way.The appearance and application of the municative approach means the reemergence and development of grammar teaching, and in fact it is not difficult to teach grammar applying CA, as long as we teachers work hard to research and practice, we can make the municative approach play a positive and effective role in grammar teaching. Principles of English grammar teaching based on municative approachWhile teaching grammar, you should bear some principles in mind so that you can teach it more effectively. The following are the main principles for grammar teaching based on municative approach.When you teach grammar, whichever technique you decide to use, it is important to keep several principles in mind. First, be certain that your students always understand what they are saying. Use demonstrations, pictures, translation or a bination of these to make certain that your students are aware of what they are municating. Secondly, when you introduce a new grammar point, select the model sentences carefully. In general, try to introduce only one new grammar point in a set of model sentences so that your students can focus on the point you wish to emphasize better. Third, always strive to keep the topic unified in theme and related to your students’ interests. Nevertheless one way to provide practice and review of the same structure, while maintaining the interest of your students, is to vary the content you use. Finally, use model sentences that reflect actual usage and try to introduce these sentences in situations in which they might actually be used by the students. Remember, in order to municate effectively, your students must just know how to use the language correctly。 the expressions of certainty and possibility。 it accepts explaining grammar, using mother language in the class and doing translation。 it emphasizes on the fluency of language and ignores unimportant mistakes and encourages students to develop their language gradually in municating。 the teaching process is for munication. Students are active in class。 third, accuracy is secondary to convey a message。 municative concept should be permeated into the process of grammar teaching, so grammar teaching will serve the teaching aim of cultivating students’ municative petence.2. Towards Communicative Approach Communicative petence. 1 The definition of municative petenceCommunicative petence refers to the ability to apply the grammatical rules of a language to form grammatically correct sentences and to know when and where to use these sentences and to whom.
