压轴题在一定程度上体现着一份试卷的选拔功能,以综合性强、难度大、区分度高,成为各地师生中考复习时关注的重点.纵观2010年各地中考试题,尤以动态几何压轴题最能体现上述要求而备受命题者青睐.这类试题的共同特点是:在平面直角坐标系中,以几何图形作为载体,常将函数、方程、全等、相似等知识融合为一体,在设计方法上都注重创新,注重在初中数学主干知识的交汇点处进行命题;在考查意图上注重对数学思想方法和能力的理解及渗透,突出对考生的探究能力、创造能力、综合运用知识能力等方面的考查.
To a certain extent, the topic of finale embodies the function of selection of papers, which is the focus of all the teachers and students in mid-term examinations focusing on comprehensiveness, difficulty and distinction.Throughout the 2010 senior middle school exam questions, especially the dynamic geometry Finale questions can best embody these requirements and are favored by the proponents.The common features of these questions are: in the plane Cartesian coordinate system, the geometry as a carrier, often the function, equation, congruent, similar knowledge into one , Focus on innovation in the design method, pay attention to proposition at the intersection of the junior high school mathematics backbone knowledge; pay attention to understand and infiltrate the mathematical thinking method and ability in the test intention, highlight the inquisition ability, create ability, comprehensive utilization Knowledge and other aspects of the test.
