英文摘要：

To solve teaching problems with highly differential classes in the class-based teaching system,a multi-level approach is adopted for Chinese language teaching based on Chinese language proficiencies of deaf college students. Instructors adopt different textbooks and teaching methods for classes based on their actual language competences. Various teaching resources are effectively integrated, and teaching effects for each level of students are maximized within limited timeframe. The multi-level teaching is an effective approach for highly differential classes in the class-based model of teaching.
