立体几何是考查空间想象能力的主要载体.高中实行课程改革以后,立体几何内容主要有两点变化:一是分成“立体几何初步”和“空间向量与立体几何”两部分,形成螺旋式排列;二是增删了一些内容,全体考生都增加了三视图,而文科考生减少了“空间向量与立体几何”部分的内容.新课程中删去了圆柱、圆锥、圆台的内容,只保留了球.对球、棱柱、棱锥、棱台的表面积和体积计算公式要求降为了解,而
Three-dimensional geometry is the main carrier to test the space imagination.After the implementation of the curriculum reform in high school, there are two main changes in the content of the three-dimensional geometry: one is divided into two parts, the “preliminary” and “three-dimensional geometry” Spiral arrangement; the second is the addition of some content, all the candidates increased the three views, and liberal arts candidates to reduce the “space vector and solid geometry” part of the content of the new curriculum to delete the column, cone, round table content , Only the ball is retained, the surface and volume calculation formulas for the sphere, prism, pyramid, and pyramid are reduced to
