按《考试说明》高中生物实验必考内容有24个。如何系统地复习好这些实验是大多数学生面对的难题,若逐一复习知识点则显零散杂乱。现介绍一种分类归纳的复习方法,将实验知识归纳为“常用试剂”、“实验分类复习”两类,将知识系统化。一、高中实验常用化学试剂归纳(一)鉴别类试剂I.斐林试剂→鉴定还原性糖→砖红色沉淀;

According to the “Exam Description”, there are 24 compulsory high school biology experiments. How to systematically review these experiments is a difficult problem faced by most students. If you review the knowledge points one by one, it will be scattered and disorderly. A review method for classification and induction is introduced. The experimental knowledge is classified into two categories of “common reagents” and “review of experimental classifications”, and the knowledge is systematized. First, high school experiments commonly used chemical reagents induction (a) Identification of reagents I. Filin reagents → identification of reducing sugar → red brick precipitation;
