近年来,全国各地的中考数学试卷中出现了不少有关图形变换的试题,如吉林省2000年试卷中出现了两道题。广西连续两年(1999年、2000年)均出现了图形变换问题。这些试题以新大纲的内容和要求为依据,注重学生对数学知识的理解、技能的掌握和综合应用能力的检测,是积极推进素质教育和数学创新思维培养的趋势,为帮助同学们搞好后期复习,现就图形变换问题,举例说明。
In recent years, there have been many questions relating to graphic transformation in the mathematics examination papers in various places across the country. For example, two questions have appeared in 2000 papers in Jilin Province. For two consecutive years in Guangxi (1999, 2000), there has been a problem of graphic transformation. These questions are based on the content and requirements of the new outline. They focus on students’ understanding of mathematics knowledge, mastery of skills and detection of comprehensive application abilities. They are actively promoting the development of quality education and the cultivation of innovative mathematics thinking. Review, now on the graphic transformation problem, for example.
