This year is the first college entrance examination in Beijing using new textbooks, and the test questions have been innovated on the basis of maintaining stability. The test questions are based on ability, strengthen the comprehensive examination of basic knowledge, and focus on the key contents supporting the discipline system. Test questions attach importance to the multiple connections of mathematical knowledge, and take the intersection of knowledge points as the starting point of test questions design. For example, (18) in science and (20) in liberal arts are both put forward at the intersection of linear programming and analytic geometry, which covers almost all the knowledge of analytic geometry and is deeply integrated in the breadth and depth of knowledge. The test questions highlight the examination of new contents such as plane vector, probability statistics and derivative, such as science (3), (8), (12), (15), (17) and (18), with a score of * * 55. New research-oriented and exploratory questions are designed, such as (13), (14) and (20) in science, which comprehensively examines high-level rational thinking and innovative consciousness and plays a good choice function. College entrance examination questions have an extremely important influence on middle school mathematics teaching. I have seen a lot of the last question in science this year, and with the background of advanced mathematics, all the students who participated in the mathematics competition have been trained in this aspect, but it is unfair to ordinary students. We hope that the college entrance examination questions can play a good guiding role in middle school mathematics teaching.
