高考对圆锥曲线知识的考查主要有以下两种形式:第一种是以填空的形式考查,主要考查圆锥曲线的标准方程、性质,以及圆锥曲线之间的关系,突出考查基础知识、基本技能,属于基础题.第二种是以解答题的形式考查,主要考查圆锥曲线的定义、性质及标准方程的求解,常常在知识的交汇点处命题,有时以探究的形式出现。有时以证明题的形式出现,该部分题目多数为综合性问题,考查学生分析问题、解决问题的能力,现用构造三角形来讨论圆锥曲线相关问题。
There are two main forms of examination of conic knowledge in college entrance examination: the first is to examine the form of fill-in, mainly examining the standard equations of conic, the nature, and the relationship between conic curves, highlighting the basic knowledge, basic skills, Belong to the basic problem.The second is to examine the form of answer questions, the main examination of the definition of conic, the nature and standard equations of the solution, often at the intersection of knowledge proposition, sometimes in the form of inquiry. Sometimes appear in the form of proving questions. Most of the topics in this part are comprehensive questions, and students’ ability of analyzing and solving problems is discussed. Nowadays, tectonic triangles are used to discuss conic-related questions.
