编者的话:中考有两种功能:选拔性功能,即为高中选拔新生;导向性功能,对初中教学起导向作用.基于这样的思路,特邀请《中学生数理化》(高中版)杂志主编师广智,从高中数学的视角谈一谈2016年中考备考策略,每期精心编制的3道数学试题,望能认真演练.动态几何问题动态几何问题涉及运动变化的数学思想,许多高中数学知识的生成都与运动变化有关,比如,函数涉及对应关系的变化,圆锥曲线涉及点的变化,因此,动态几何问题是中考命题的重点.
Editor’s Note: There are two functions of the exam: the selective function, that is, high school selection of freshmen; oriented function, a junior high school teaching play a guiding role.Based on this idea, special invited “high school mathematics” (high school) magazine editor in chief Chi, from the perspective of high school mathematics talk about the 2016 senior high school entrance examination preparation strategies, each carefully prepared three math test questions, hope to practice .Dynamic geometric problems Dynamic geometric problems involving changes in mathematical thinking, a number of high school mathematics knowledge students Chengdu is related to the change of movement. For example, the function involves the change of the corresponding relation, and the conic curve involves the change of point. Therefore, the dynamic geometric problem is the focus of the senior high school entrance examination.
