高考的目的之一是综合考查学生灵活运用所学高中数学知识分析问题、解决问题的能力.由于一套高考试卷的承载量有限,那么如何用有限的试题更全面地考查学生在高中所学的数学知识呢?综合试题的命制担负着这一重要使命.试题的综合化是新课改后高考命题的热点和趋势,也是新课改最大的特色及发展方向,对学生提取信息的能力和对知识的运用迁移能力也提出了更高的要求.圆锥曲线内容在高考中的地位不言而喻,将此类试题的命题与其他知识进行交汇,容易命制出高质量的综合问题,进而实现高考考查的目的和要求,因此备考中要注重圆锥曲线知识的系统化、网络化,加强综合能力的训练.下面就圆锥曲线中具体交汇问题进行例析.
One of the purposes of college entrance examination is to comprehensively examine the students ’ability of using the knowledge of high school mathematics to analyze and solve problems flexibly.With a limited load of a college entrance examination paper, how to use a limited number of questions to examine students’ Mathematical knowledge? The test of comprehensive questions bear the important mission. The integration of test questions is the hot topic and trend of college entrance examination proposition after the new curriculum reform, but also the biggest feature of the new curriculum reform and development direction, the ability of students to extract information and The application of knowledge transfer capacity also put forward higher requirements.Concrete curve content in the college entrance examination status is self-evident, the proposition of such questions and other knowledge to meet, easy to produce high-quality comprehensive problem, and thus So as to realize the purpose and requirement of college entrance examination and examination, so we should pay attention to systematic and network of conic knowledge in preparation for examination, and strengthen the training of comprehensive ability.In the following, the concrete problems of conic curve are analyzed.
