20 17 Jiangsu college entrance examination math problems continued the style of previous years, focusing on the foundation and close to textbooks. The examination questions are based on the basic and comprehensive examination, and pay attention to the examination of ability, which embodies the proposition principle of ability conception. The examination paper is stable in structure, wide in knowledge points, focused, clear in level and gradually deepened, which is convenient for students to solve problems.

Pay attention to the foundation and highlight the trunk: Mathematics test questions are closely related to teaching materials and have the characteristics of "easy to use". Fill in the blank1-10, solve the problem 15, 16 and the additional questions A, B, C and D of 2 1 are easy questions, and students can get these basic points through proper operation. Fill in the blanks 1 1- 14 is somewhat comprehensive, with high thinking content, and pays attention to the examination of mathematical thinking methods, but the ideas and methods for solving problems are still universal and will have a good degree of differentiation. The problem-solving number 17 is analytic geometry, which has changed the situation of large calculation in the past. Students can do it by hand and get better scores. 18 is related to the knowledge of plane geometry. The key is to transform the problem and highlight the examination of mathematical thinking methods. If we can enhance some practical applications, we can better reflect the application value. The 22 nd additional question is also a test question expected by teachers and students, so it is natural to pass the space vector operation. 19, 20, 23, and additional questions are all set at different levels, and the difficulty of each event is progressive and spiraling. If the starting point is right, all students can get points, and candidates at different levels can gain something.
