语境理论是外语教学中创设情景的理论根据。在大学英语精读教学中，从背景入手，经过对多义词、文化负荷量较大的词语等难点的讲解，最后再回到篇章教学上来，这一过程的展开都是以语境理论为基础的。使用体语创设情景，可以增强课堂教学的生动性，造成良好的教学气氛。 Context theory is the theoretical basis for creating scenarios in foreign language teaching. In the process of college English intensive reading, starting from the background, through the explanation of the difficulties such as polysemy, words with heavy cultural load, and finally back to the chapter teaching, the development of this process is based on the context theory. The use of body language to create scenarios can enhance the vividness of classroom teaching, resulting in a good teaching atmosphere.
