Recent years, most universities and colleges have been reforming the English as a foreign language (EFL) curriculum system in China. Some reformed EFL curriculum into English for Specific Purposes (ESP) courses, for instance, while some conducted a graded teaching model in EFL teaching. However, the effect of this reform was not so good, especially at science and technology institutes. Therefore, in view of different opinions to classification of foreign language teaching, the classification scheme of English teaching was improved and rebuilt at first, based on the analysis of the learners' feedback from the perspective of learner's needs on the current EFL curriculum system of China's science and technology institutes under graded teaching model. And then a new EFL curriculum system of China's science and technology institutes under graded teaching model was designed based on learning-centered approach to course and curriculum design to promote the development of EFL teaching and China's ESP courses and accordingly meet nation's needs for cultivating international and integrated high-quality talents of foreign languages.
