PAD (Presentation-Assimilation-Discussion) is a new teaching mode put forward by Professor Zhang Xuexin of Fudan University, which has attracted the attention of academic circles in recent years and has been widely used in teaching practice in China. After personal practice in college English courses, the author believes that in order to optimize the teaching and learning effect, we need to combine this model with the "literature circle" in reading program and attach great importance to the pivotal role of peer support in the learning procedure. Only in this way can we really achieve the goal of cultivating talents with core literacy. The current study focuses on the implementation of college English teaching practice based on the PAD class and its effect compared with traditional teacher-centered classroom teaching.
