化学习题千变万化,但我们总能够在其中包含的具有标志性的、相同或相似的化学性质中,通过一层层的抽丝剥茧,逐一排除,逐渐使其变得清晰明了,最终寻找到正确答案。而在这分析、整合与探究的过程中,不断总结规律,从而达到触类旁通、闻一知十的效果。一、破解一道题,“触类旁通”高中化学的某些习题,初接触时往往会让学生有些眼花缭乱的感觉。但是只要用心去总结和整理,便不难发现有许多规律可循。仅仅通过一道题
Chemical exercises are ever-changing, but we can always get rid of them by layers of extermination in the iconic, identical or similar chemical contained therein, gradually making them clear and eventually finding the correct answer. In the process of analysis, integration and inquiry, the law is constantly being summarized so as to achieve the effect of bypassing and smelling one by one. First, to crack a problem, “Touch Class ” some of the exercises in high school chemistry, the initial contact with students tend to make some dazzling feeling. But as long as the intention to sum up and organize, it is not difficult to find that there are many laws to follow. Just pass a question
