随着高考制度的改革,二次曲线应用在高考中的地位不可忽视,分值在17~22分之间,题目多数出现在选择题、填空题和解答题的中等难度题目的位置。为了使学生取得好成绩,需要掌握二次曲线更多的性质和定理,这样解决问题就会变得得心应手,游刃有余,这也迫使教师不得不去研究和探索二次曲线的其他性质。笔者现将自己的一些探索作如下整理,以飨读者。 With the college entrance examination system reform, the application of the quadratic curve in the college entrance examination in the position can not be ignored, the score is between 17 to 22 points, most of the questions appear in the multiple choice questions, fill in the blank questions and answer the questions of the middle of the problem position. In order to get good grades, students need to master more properties and theorems of the quadratic curve. Solving the problem will become handy and smooth, forcing teachers to study and explore other properties of the conic. I will now explore some of their own as follows to readers.
