高考数学复习,大致可分三个阶段,每一个复习阶段都各有各的侧重点,各方面的要求在不同阶段逐步在提高。第一轮复习,重点是夯实基础,构建知识网络,生长知识点,了解数学知识和理论的形成过程,理解解决数学问题的思维过程,注重基础知识的复习和基本技能的训练,紧扣课本。因而对第一轮课堂教学中的例习题选取提出了较高的要求,怎样才 The review of mathematics in the college entrance examination can be roughly divided into three phases. Each review phase has its own emphasis, and the requirements in various aspects are gradually being improved at different stages. In the first round of review, the focus was to lay a solid foundation, build a knowledge network, grow knowledge points, understand the formation process of mathematical knowledge and theory, understand the thinking process of solving math problems, pay attention to basic knowledge review and basic skills training, and closely follow textbooks. Therefore, higher requirements were placed on the selection of examples in the first round of classroom teaching.
