近年,全国各地中考数学试卷中的“压轴题”具有一定的探究性和较强的选拔性,设计新颖,富有创意,重在考查学生的数学思想方法和探究问题的能力,而数形结合是重要的数学思想方法之一,同时数形结合的精髓是函数,函数的核心是运动变化,这样“运动型”的函数问题是近几年中考数学试卷“压轴
In recent years, the ”end-point questions" in the mathematics examination papers in the national examinations around the country have some exploratory nature and strong selection. They are novel in design, creative, and focus on examining students’ mathematical thinking methods and ability to explore problems. Combining is one of the important methods of mathematics. At the same time, the essence of the combination of numbers and shapes is a function. The core of a function is a movement change. The function of this “sports type” is a mathematics test in recent years.
