Interaction is the key to student learning. It is so vital for successful teaching that teachers should try to understand interaction theories and then convert them into coherent programs of action that fit their existing routines. Differing from the traditional English teaching methods, in the interactive classroom, the teachers should change their original roles so as to create an environment to promote interaction in English classroom. The interaction does really benefit the English teaching and learning. There are many reasons for using activities which promote classroom interaction. What’s the most, teachers can make the full use of the most valuable resource—the students themselves. Not only are the students ready and willing to work together, but also, they tend to learn better in a comfortable environment. Secondly, it seems that the students only exchange information on a specific topic, Thirdly, the students may be more interested in the new words and phrases offered by sings, movies, videos, etc. rather than the words and phrases they have learned in the textbooks. Let alone the grammar. So when scenarios are set in the classroom, the related interaction will help the students to enlarge their vocabularies and broaden their minds by exchanging information. In addition, it is very motivating for students to realize that, even at this early stage, they can communicate information successfully in English. From the above we can realize that interactions between teacher and students are how important in a classroom especially in middle school English classroom. Only attract student’s attention to English.

II. Present Situation of English Classroom Interaction in Middle Schools
    
2.1 Aimless Class Interaction
At present time, on English classroom in middle school, we can find that there are lots of classroom interactions. Such as teacher asks questions and students respond to it, activities between students and teacher or between students. The teacher raises the questions constantly, and students answer the questions immediately without any thinking. And among these questions, many questions are valueless for learning, while some questions are unfit for the learners’ level. In such teaching model, the teacher just focus on the interaction forms rather than the interaction contents. Under that situation, the students have achieved a little, and they become the sacrificial lamb of teaching. There is no doubt that students should be active in classroom teaching, but here, the aim is not obvious and it may make the interaction meaningless. As for middle school students, their thoughts and mode of thinking are independent. Very often they are not satisfied with teacher’s requests or behavior. So before the class, the teacher should think over the feasibility of the interactive activities, and take the students into consideration. If the students can not involve in, the interaction will be meaningless or may take some side-effect. 中学英语课堂交流策略研究(2):http://www.751com.cn/yingyu/lunwen_11065.html
