在近几年的中考试题中,考查动点生成函数图象问题逐渐成为一种趋势.这类问题通过点、线或图形的运动构成一种函数关系,生成一种函数图象,将几何图形与函数图象有机地融合在一起,体现了数形结合的思想,能充分考查学生的观察、分析、归纳、猜想的能力以及综合运用所学知识解决问题的能力.因此,这类问题一般会做为选择题的压轴题出现,如何才能既快又准确的找出答案成为考生亟待解决的问题.本文以中考中几个动点类问题为例进行分析,以 In the middle school entrance examination questions in recent years, it is becoming a trend to examine the problem of moving point generation function images, which form a kind of functional relationship through the movement of points, lines or figures to generate a function image, And function images are organically integrated together, which embodies the idea of ​​combining numbers and forms, fully examining students’ abilities of observation, analysis, induction and conjecture, as well as the ability to comprehensively apply their knowledge to solve problems.Therefore, such problems are usually As a finale of multiple-choice questions appeared, how to quickly and accurately find out the answer candidates become urgent problems.In this paper, the analysis of a few moving points in the class as an example to analyze, with
