认真分析近年高考化学实验试题的走向,高考化学实验题命题中的“综合”主要体现在以下两个方面:第一、在实验原理、实验仪器和实验操作三条“线”的基础上,向“原理+仪器”、“仪器+技能”、“原理+技能”三个交叉,综合的层面甚至向“原理+仪器+技能”三维立体结构发展,实现化学实验知识与技能的综合考查;第二、化学实验与元素化合物、有机化学、化学计算、化学概念和原理等各个板块中相关知识综合在一起进行考查;解答试题的重要途径1.细心领会实验原理。化学综合实验题的原理大部分是书本上已有的知
Carefully analyze the direction of recent college entrance examination chemistry test questions. The “integration” in the proposition of chemical experiment subjects is mainly reflected in the following two aspects: First, based on experimental principles, experimental instruments and experimental operation of three “line” basis On the other hand, we have developed three principles: “Principle + Instruments,” “Instrument + Skills,” “Principle + Skills,” and the three-dimensional structure of “Principle + Instrument + Skills” has been developed. Comprehensive examination of knowledge and skills in chemical experiments; Second, chemical experiments and elemental compounds, organic chemistry, chemical calculations, chemical concepts and principles, and other related knowledge in various sections are taken together for examination; an important way to answer questions is to carefully understand the experiment. principle. Most of the principles of chemical synthesis experiment topics are already known in books.
