复数在高考数学中占的比重较小且难度不大,一般以选择题或填空题的形式出现,被许多教师和学生戏称为“鸡肋”.事实上,虽然复数试题的难度较小,但非常灵活,具有活而不难的特点,且常考常新,要求考生具有灵活处理问题的能力.因此复习时应注重基础性、品味交汇性、关注新颖性,对复数的有关概念及代数形式的运算等要熟练掌握,同时还要注意数形结合思想、分类讨论思想、等价转化思想及复数问题实数化方法等的灵活运用. Plurality accounts for a small proportion of the college entrance examination mathematics and it is not very difficult. It usually appears in the form of multiple-choice questions or fill-in questions. Many teachers and students are jokingly referred to as “chicken ribs.” In fact, although the difficulty of plural test questions is small, But it is very flexible, has the characteristics of being alive but not difficult, and is often subject to new ones. It requires candidates to have the ability to deal with problems flexibly. Therefore, when reviewing, we should pay attention to the basics, the convergence of tastes, the attention to novelty, and the concepts and algebras of plurals. Formal operations must be mastered, and at the same time, attention should be paid to the flexible use of the combination of number and shape ideas, classification and discussion ideas, equivalent transformation ideas, and real numbers of complex problems.
