近年来,以过氧化物为素材的信息型实验探究题在中考命题中频频出现,考生尽管对实验原理、实验操作要点的掌握都比较扎实,但对于文字的表达就出现了词不达意、操作过程的逻辑顺序不能准确表达、遗漏重要操作步骤的情况,造成了失分。因此了解这类信息型实验探究题的命题特点,掌握这类试题的解题技巧,是实现中考化学高
In recent years, the peroxide-based information-based experimental exploration questions frequently appear in the middle school entrance examination questions. Although the examinees have a solid grasp of the experimental principle and experimental operation points, the word expression is not meticulously expressed. The logical sequence of the process can not be accurately expressed, omission of important operational steps, resulting in the loss of points. Therefore, understanding of the proposition of this type of information-based experiments to explore the characteristics of these questions to master the problem-solving skills is to achieve a high test
