In order to develop the necessary characters and key abilities that students need to adapt to their lifelong development and social development，Chinese as the mother tongue should play its first role. Chinese subject learning is based on the development of Chinese students’ core literacy，and according to the Chinese Curriculum Standards for Compulsory Education，the class hour objectives are determined by gradation to ensure the effective implementation of teaching. In order to solve the problem of quantity and quality of students’ reading，it is recommended to classify and classify the unit contents of the textbook. According to the dimensions of key abilities，reading aid tools are designed to stimulate students’ learning interest to the maximum extent and cultivate students’ abilities of independent learning and cooperative inquiry. The evaluation index of reading ability is made by referring to the level of ability standard，which serves as an important basis for teachers to teach and students to learn，and scientifically and effectively guide students to gradually form key reading ability and lasting reading motivation，so as to improve students’ comprehensive Chinese literacy.
