However, the existing teaching mode, which emphasizes instrumentality and ignores humanity, greatly restricts the full play of the ideological and political educational function of college English courses.

Combining "Dao" with "Shu" to enhance the ability of education, strengthen the education guarantee, optimize the teaching design, so as to harmonize instrumentality and humanism, and realize the "Trinity" talent cultivation goal of knowledge imparting, ability cultivating and value shaping.
