Basically, the review work of candidates one month before the college entrance examination has been basically completed, so what else needs to be done in the last month? In fact, a good sprint in the last month can improve quite a lot of scores.

First, pay attention to special training and understand mathematical ideas.

The review of the second stage of college entrance examination mathematics focuses on the review of knowledge and methods. Some special exercises can be arranged according to the needs of students. The topics we usually talk about are mainly divided into two categories, namely, knowledge topics and methodology topics. Multiple choice questions, application questions, function questions, series questions, inequality questions, triangle questions, analytic geometry questions, solid geometry questions, etc. They are all knowledge topics, and the ideas of functions and equations, the combination of numbers and shapes, classification and discussion, and transformation are methodological topics. Mathematical thinking method is the essence of mathematics. Only through summarization, understanding and application can mathematical knowledge and skills be transformed into the ability to analyze and solve problems, and students' problem-solving ability and mathematical quality can be by going up one flight of stairs.

Second, pay attention to hot issues and attach importance to the intersection of knowledge.

Carefully analyze the examination syllabus, study the trend of college entrance examination in recent years and the proposition law of simulated training questions in various cities, and determine the content of key review and training. In recent years, there are more and more questions in the new content of college entrance examination. The scores of simple logic, plane vector, linear programming, space vector, probability statistics, limit and derivative are increasing year by year. Therefore, we should focus on reviewing this kind of knowledge, especially vectors and derivatives, which provide new ideas and methods for solving traditional mathematical problems, such as solving plane analytic geometry and solid geometry with vectors and studying functions with derivatives. Of course, some original key contents, such as function, sequence, inequality, solid geometry, analytic geometry, etc., should still be highly valued. The intersection and combination of knowledge is still a hot issue in college entrance examination, so it is necessary to carry out necessary special review, such as focusing on reviewing functions, inequalities, derivatives, equations, the synthesis of series and functions, the synthesis of plane vectors and trigonometric functions, analytic geometry and so on.

Third, return to textbooks, check for leaks and fill gaps.

It is not difficult to find that many questions can be found in textbooks, and many college entrance examination questions are variations, transformations and integrations of the original textbooks. Therefore, it is necessary to return to textbooks, implement double bases with the help of textbooks, build a complete knowledge system with the help of textbooks, and check for gaps with the help of textbooks. This paper systematically reviews and summarizes the knowledge system of the textbook, understands the connotation, extension and connection of each knowledge point, and attaches importance to the description and proof of important theorems in the textbook, such as the theorem of three perpendicular lines in solid geometry and the judgment theorem of the relationship between lines and surfaces. Look at the exam notes and the analysis of test questions, make sure there are no knowledge blind spots, return to the basics, return to the latest college entrance examination questions, and master general methods, such as solving trajectory problems in analytic geometry, solving general formulas of series, and summing series. Pay attention to the examination of new content (such as simple logic, vector, derivative, probability, statistics, etc.). ) in the new textbook, the research and inspection of the internship assignments and research topics in the textbook, the contents of the reading materials in the textbook, such as the number of elements in the collection, the calculation of savings, etc. The research project reflects the research and development direction of the new curriculum and should be paid more attention. For example, the calculation in installment shows the application value of mathematics.
