But in China, unfortunately, few achievements have been made in the field of reading theory research. Thus, in order to ameliorate our reading teaching, it is urgent for us to set up our own system of reading theories. The author, after studying carefully the present reading models in China and by absorbing the quintessence of foreign reading theories, ventures to suggest the “discourse word discourse” model. The model gives full thought to the characteristics of Chinese college students and thus suits a reading classroom in China better. However, the comprehension factors involved in the model are far from exhaustive and the model itself leaves much room for modification and addition.\;展开更多

Of the three models, interactive teaching model has shown to have advantage over the other two, the situational teaching model and the task-based Instruction model. It is concluded that it is beneficial to improve teaching effects in military English teaching if the teacher can stimulate students to involve themselves more in class. To do so, it is necessary to strike a balance between the learners＇ language input and output so as to ensure that the input knowledge be consolidated and digested through practice in output.展开更多
