在近年的物理中考中时常出现一些关于信息的题目,这类题将解题所需的条件和各物理量之间的内在关系包含于文字、图象、表格之中,要求学生能根据所学知识对这些信息进行充分提取、适当筛选、有效加工和处理;这类题较独特,能较好地考查学生分析、解决问题的能力和创新能力,注重能力培养,体现出素质教育的特点,成为中考热点题型。长江是我国的第一大江,孕育了中华民族几千年的文明,长江又是带动当今中国腾飞的一条巨龙,以她为载体的物理信息题频频出现,请看下面两道与长江有关的信息题。例1我国正在建设的长江三峡工程是一座具有防洪、发电、航运、养殖和供水等巨大综合利
In the recent physics examinations, there are often topics concerning information that include the intrinsic relationship between the conditions required for problem solving and the physical quantities in texts, images, tables, and require students to learn from the knowledge they have learned. This information is fully extracted, properly screened, effectively processed and processed; these types of questions are more unique, can better examine students’ abilities of analysis, problem solving and innovation, pay attention to ability training, and reflect the characteristics of quality education and become a test. Hot questions type. The Yangtze River is China’s largest river, which has nurtured the civilization of the Chinese nation for thousands of years. The Yangtze River is also a dragon that has driven China’s takeoff. The physical information questions that she uses as a carrier frequently appear. See the following two related to the Yangtze River. Information questions. Example 1 The Yangtze River Three Gorges Project under construction in China is a large-scale integrated project with flood control, power generation, shipping, aquaculture, and water supply.
