Body language refers to the various movements through the whole body, thus instead of language to achieve the goal of expressive communication. In Peter Collett’s book ‘The Book Of Tells’, we can clearly understand body language, one of the language types, and its usage and performance in different situations. It is a required course for actors, as well as for the teachers. Different lesson types in different cases of body language are also very distinct. In a word, rich and accurate body language can bring English teachers better interpretation of different lessons. What’s more, rich body language used in English class can not only stimulate students’ interest in learning English and attract their attention into class.
