From the table, we can see the the second and fouth methods of lead-in are often used by teachers. The ratio of the game strategies is about 37 percent, the question strategies, story strategies and song strategies are less used, and the multimedia strategies become widely used.
    Among the six forms of lead-in, teachers can use different methods to lead-in the new lessons. Yet in general, they can not find which forms are better for middle school students. In the modern society, they prefer to choose the multimedia teaching. In almost every classroom is full of computers. But we must think computers and multimedia really offer some convenience and proper resources for teachers. In English classroom, question, game, song and story strategies can not use widely by English teachers. In China, under the pressure of College Entrance Examination, most English teachers put all their heart into the explanation of grammar and language points, they ignore design the classroom lead-in, even omit the step of lead-in and they are the main body of teaching process.
Besides, Lead-in is often completely neglected by teachers in the real English classroom teaching. They just regard lead-in step as a superficial form. Some teachers often use some words like keep quiet and class begin to lead the new lessons. It is obvious that they ignore the function of lead-in. 中学英语课堂导入艺术浅析(6):http://www.youerw.com/yingyu/lunwen_7673.html
