有关高考的研究一直是各位教育工作者最关心的课题，其中圆锥曲线部分是高考中的必考内容且分值占比大，椭圆，双曲线，抛物线知识点多且考察题目运算复杂，容易失分，探究全国二卷中这部分考点考察形式的变化显得尤为重要。本文将使用文献研究法，比较研究法，统计分析法，针对2014—2018年全国二卷中圆锥曲线部分进行整理分析，研究考察题型与知识点分布的变化。发现圆锥曲线部分由一道双曲线或抛物线作客观题、椭圆作主观题题的格局变为两道客观题一道主观题同时兼顾双曲线抛物线椭圆三部分内容的形式，客观题中双曲线离心率仍是热门题型。对比文理科圆锥曲线部分，相似度越来越高，高考在向我们释放文理不分科的信号。由此给课堂教学提出具有建设性的策略，帮助新教师更好的理解数学教学内容以及高考形势。

The research on the college entrance examination has always been the topic that educators are most concerned. Among them, the conic section is the compulsory examination content in the college entrance examination and has a large percentage of scores. Ellipse, hyperbola and parabola have many knowledge points, and the operation of the examination questions is complicated and easy to lose scores. Therefore, it is particularly important to explore the changes in the examination forms of this section of the new standard Ⅱ test paper.This paper will use the methods of literature research, comparative research and statistical analysis to sort out and analyze the conic sections in the new standard Ⅱ test paper from 2014 to 2018 in order to study the changes in question types and knowledge distribution. It was found that the pattern of conic section changed from a hyperbolic or parabolic objective tests and an ellipse as the subjective question to two objective tests and a subjective question, taking into account the three parts of hyperbolic parabola ellipse. The eccentricity of hyperbola is still a popular question in objective tests. Compared with the conic sections of arts and sciences, the similarity is getting higher and higher. The college entrance examination is sending us the signal of cancel the division of students into different tracks in high school. Therefore, constructive strategies are put forward for classroom teaching to help new teachers better understand the content of mathematics teaching and the situation of college entrance examination.
