四边形和函数图象都是中考命题中必考的知识,而以四边形为载体,将四边形和函数图象密切结合、巧妙渗透“运动”观点与思想的试题成为近年中考选择题中一大靓点.这类试题构思新颖,知识涵盖面宽,体现了圆形语言与符号语言的相互转化,是中考命题的一种趋势.下面以近年中考试题为例 The quadrilateral and function images are the necessary knowledge in the examination proposition. Using the quadrilateral as the carrier, the questions that closely integrate the quadrilateral and functional images and ingeniously infiltrate the viewpoints and ideas of “motion” have become a big problem in the multiple-choice questions in recent years. These types of questions are novel in concept, cover a wide range of knowledge, and reflect the mutual transformation of circular language and symbolic language. This is a trend in the proposition of the examination.
