The construction of the multi-dimensional ideological and political education ecological system in college English curriculum under the three-whole education pattern expands the scope of the ideological and political education system in college English curriculum, makes the teaching and teaching auxiliary units and related functional units form close interactive relations, and constructs the multi-dimensional ideological and political education cooperative body. It breaks the single system of ideological and political education of college English based on classroom teaching, integrates ideological and political education into the whole process of education, and promotes the construction of a benign ecological system of ideological and political education.
