课本中蕴涵许多经典的习题,如果我们在解题之后,再深入反思问题的条件与结论及图形的结构,常常可以发现其中隐含的解决问题的数学模型,当我们灵活运用所归纳提炼出的这些模型解决类似的中考数学问题时,便可以强化思维的敏捷性,快速找到解决问题的突破口.【引例】(课本习题第44页“拓广探索”
There are many classical exercises contained in the textbook. If we reflect on the conditions and conclusions of the problem and the structure of the graph afterwards, we can often find out the implicit problem-solving mathematical model. When we make flexible use of the refined When these models solve similar senior high school entrance examination math problems, they can strengthen the agility of thinking and quickly find a breakthrough point to solve the problem.
