从以学生角度解决一个具体椭圆定点问题入手，介绍了求解定点问题的方法并进行了升华归纳；通过变式拓展过渡到定值问题并归纳其解题思路，从教师角度为方便解题和命题需要，加强了椭圆类定点定值问题的横向探究和双曲线、抛物线的纵向探究，并形成了类题模板。%Based on a solving fixed⁃point problem of an ellipse from the student angle, this paper introduces the method for solving the fixed⁃point problem and makes summarization, generalizes the solution path from variant extension to definite value problem, in order to be conveniently solving the problems and set a question from teacher angle, consolidates the horizontal exploration for the fixed⁃point and definite value problem of an ellipse and vertically studies hyperbola and parabola to form a class of problem templates.
