复数在高考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 relatively small proportion of the college entrance examination and is not very difficult. It usually appears in the form of multiple-choice questions or fill-in questions. It is often referred to as “chicken ribs” by many teachers and students. In fact, although the difficulty of plural questions is small, It is flexible, lively and not difficult, and often used for new examinations. It requires 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, the concept of complex numbers, and the forms of algebra. Computation, etc. should be mastered skillfully, and at the same time, attention should be paid to the flexible use of combination of number and shape ideas, classification and discussion ideas, equivalent transformation ideas, and real number methods of complex numbers.
