实验类题目是高考的必考内容之一:所以对常见实验题进行分类,并逐一掌握其应考策略是高考备考中重要的一环.一、区分实验组和对照组生物实验设计的一个基本原则就是要设计对照实验.在确定实验组和对照组时,首先要明确该实验的目的.实验组是针对实验目的来控制,干预研究对象而进行的,是用来证明实验假设的实验操作.对照组是为了排除其他无关因素或非研究因素的干扰而进行的操作.实验组、对照组的区分常以选择题、填空题的形式出现.需要考生灵活适用减法原理、加法原理和一般的逻辑分析法去
Therefore, it is an important part of college entrance examination preparation to classify the common experiment questions and master them one by one. First, to distinguish the experimental group and the control group, a basic principle of biological experiment design Is to design a control experiment in determining the experimental group and control group, we must first clear the purpose of the experiment.Experimental group is for experimental purposes to control and intervene in the study, and is used to prove the experimental hypothesis experimental operation.Control Group is to exclude other irrelevant factors or non-research factors interfere with the operation of the experimental group, the control group is often the distinction between multiple-choice questions, fill in the blank form of the problem. Need to apply the principle of subtraction flexibly, addition principle and general logic analysis Law to go
