一、考情分析立体几何是培养学生的空间想象能力和逻辑推理能力的一门学科,同时也培养学生的类比思想、辩证思想和转换化归思想。每年高考中立体几何部分基本保持在2～4道试题,其中含1道中等难度的综合题。综合题常以某种几何图形(棱柱、棱锥、翻折图形、不规则图形)为载体,考查点、线、面的位置关系,求角和距离,求体积、面积和求有关量的最值,分步设问,逐步加大难度。 First, the test analysis Three-dimensional geometry is to cultivate students ’spatial imagination and logical reasoning ability of a discipline, but also develop students’ analogy, dialectical thinking and conversion to the thought. Each year the college entrance examination in the geometric part of the basic remained at 2 to 4 questions, including a comprehensive examination of intermediate difficulty. Comprehensive title often with some geometry (prism, pyramid, fold graphics, irregular graphics) as the carrier, check the point, line, surface location, angle and distance, find the volume, area and find the value of the most relevant , Step by step asked, and gradually increase the difficulty.
