Senior three review pays attention to textbooks and returns to basics. The comprehensiveness, foundation and typicality of the exercises in the textbook are incomparable with any data. On the basis of teaching materials, on the basis of summarizing the thinking methods of teaching materials, the teaching materials are improved and adapted, so that the knowledge and thinking methods of teaching materials can be sublimated, rather than simply reusing teaching materials. Therefore, in order to understand the textbook thoroughly, it is necessary to learn the examples, exercises and review reference questions in the textbook, and also pay attention to the study of internship assignments and research topics.

(1) When reviewing each chapter, contact the corresponding part of the textbook, understand the knowledge and methods provided by the textbook, understand the derivation process of theorems and formulas and the solution process of examples, and find the connection between examples and exercises;

(2) If you encounter obstacles in problem-solving training, you should have the habit of consulting textbooks, find out your own shortcomings in knowledge and methods through textbooks, and try to return the problems to the examples in textbooks;

(3) Starting from the experience and methods accumulated in review, pay attention to exploring the basis of these experiences, methods and laws from textbooks;

(4) In every step of review, we should pay attention to enriching the connotation of textbooks and revealing the relationship between textbooks and college entrance examination questions.

(5) The expression of problem-solving should be based on teaching materials, avoiding the abuse of symbols, the arbitrariness of language and the generalization of graphic methods in review materials, and standardizing them through teaching materials;

(6) Pay attention to expanding the training function of textbook topics by changing the way of asking questions, increasing or decreasing the changing factors and extending the popularization as necessary. Nowadays, textbooks are generally routine answers. We should think about the functions of choosing, filling in the blanks and exploring, and explain them from the aspects of background, reality and source, so that the use of textbooks can run through the review of college entrance examination.
