综观近两年高考题,无论是全国卷还是各省市自主命题卷,立体几何考查的重点仍然是三视图、空间的平行与垂直关系、简单几何体的表面积与体积、空间角与距离的计算等知识.题型涵盖选择题、填空题和解答题,足见立体几何内容在高考中的重要程度.本期特组织了5篇有关上述内容的文章,希望同学们读后能够有所总结、有所领悟、有所收获. Looking at the entrance exams in the past two years, both the national volumes and autonomous volitions of provinces and cities, the focus of the three-dimensional geometric examination is still the three views, the parallel and vertical relations of space, the calculation of the surface area and volume of simple geometric bodies, the calculation of spatial angles and distances Topics covered multiple choice questions, fill in the blank questions and answer questions, showing the importance of three-dimensional geometric content in the college entrance examination.This issue has organized five articles on the above content, I hope the students after reading can be summarized, some comprehension, gain something.
