As all of us know, grammar plays a really important part in learning foreign language. Without grammar, learners can"t produce the language correctly or transfer their thinking so that the listeners can understand what the speaker means. Most of learners considered that grammar periods are boring because of traditional teaching method which sticks to the black board and can"t make students speak out after the teacher"s presentation. Therefore, the question: “What may be the suitable methods of teaching grammar in a class of 60-non-English major students?” is raised. There have been many ways to transfer grammar to leaners so far such as deductive, inductive approach, PPP or ESA method. In this paper, I would like to apply ESA method to the presentation of grammar point of comparisons in Unit 7 in A2 level of Life, published by National Geographic Learning. The purpose of this appliance is to estimate the effectiveness of the ESA method on nonEnglish major HUFI student based on their preferences, understanding the lesson and their ability to apply the grammar point in real life.
