1. Reflect the concept of new curriculum standard and realize a smooth transition. The examination paper is closely related to Jiangsu examination syllabus, and the examination of new contents is mainly about basic concepts, basic formulas and basic operations, which is not difficult. The examination of traditional content is moderately innovated on the basis of maintaining stability. For example, the seventh question examines geometric probability for the first time.
2. Pay attention to the general method. The examination paper downplays the special skills, comprehensively examines the general methods, and reflects the proposition requirements based on the examination of knowledge, methods and abilities. For example, 17 analytic geometry examines the intersection of two straight lines and the points on the curve. Question 20 examines the relationship between roots and coefficients and factorization of cubic equations with extreme values as carriers. 19 examines arithmetic progression's definition at many levels in the form of a new definition.
3. Reflect the application of mathematics and pay attention to social life. 10 is to find the maximum value of the basic inequality based on the freight and storage fees in real life, and 18 is to solve the triangle problem based on the common regular quadrangle and regular quadrangle, which reflects the fairness of the background of the test paper design problem and has a good promotion effect on mathematics teaching.
4. In the part of additional questions, the first four questions are relatively simple in examining knowledge points, and the methods are relatively clear, which makes it easier for students to start. The two required questions are changed from the routine, which not only examines the application of space vector in solid geometry, but also examines the probability distribution and expected value, and not only examines the calculation ability, but also examines the thinking ability.
