2007年全国高考理科综合能力测试第一套试题中的化学实验题考查的是碳和水蒸气反应后的产物的检验,是一个实验设计题,取材常规,也是学生非常熟悉的背景材料。这说明试题起点低,但是对能力的要求并不低,要求学生对实验原理及过程有一个整体的理解和认识,即学生必须具有较强的整体思维能力,方可顺利解答。这道题综合考查了实验装置的连接,装置中每一部分实验仪器的作用以及一些仪器中要添加
In 2007, the chemistry test questions in the first set of questions for the National Comprehensive Test for Science of Science in the National College Entrance Examination were examined after the reaction of carbon and water vapor. It is an experimental design question, and is based on routines. It is also a background material that students are familiar with. This shows that the starting point of the test questions is low, but the requirements for the ability are not low. Students are required to have an overall understanding and understanding of the experimental principles and processes, that is, students must have a strong overall thinking ability before they can successfully answer. This question comprehensively examined the connection of the experimental device, the role of each part of the experimental instrument in the device, and some instruments to add
