In the context of the new curriculum reform, high school Chinese urgently needs to break the traditional teaching model and adopt innovative teaching oriented towards the cultivation of core literacy. Based on the actual teaching problems in Chinese teaching and in combination with the principle of consistency of "teaching-learning-assessment", this paper proposes strategies such as the construction of critical reading, the implementation of situational teaching, the construction of a diversified evaluation system and the integration of teaching resources to achieve the coordinated development of students' language ability, thinking quality, cultural understanding and aesthetic ability.
