It is not only an acceleration for teaching proceeding but also making it easier for students acquiring new knowledge if the teacher can grasp the attention of students and make them initiatively engaged in classroom teaching within the few minutes at the beginning of a class. Lead-in is to draw the attention of students, arouse their learning interest and exception, active their thinking, contact the connection between what they have learned and what they will learn, finally get to learn the new knowledge naturally and smoothly.

Secondly when designing the lead-in part, teachers do not according to different teaching material but repeatedly use the same lead-in which they are familiar with without any changing which ends up failing to bring students expectation and gradually lose its function. Last but not least, the designing of lead-in lack of reflection which is not based on the interest and experience of students, as a result, it fails to draw students’attention and participation rate of students in classroom teaching stays low.Based on the definition, connotation and essentiality of lead-in, the author started this research on the lead-in of different types of English courses which explored the following aspects.
