数学中考压轴题的综合性强、考察面广、方法灵活多变,对学生数学能力要求很高.其实,大多数综合题虽然有一定的难度,但考查的还是学生对基本知识的掌握,是在基础知识上的综合.学生之所以对数学综合题有恐惧感,是因为平时没有很好地总结经验、规律,没有举一反三,触类旁通.下面以一道中考压轴题为例,解析数学综合题的变式训练.原题(2015泰安)
In fact, most of the comprehensive questions have a certain degree of difficulty, but the test is still students grasp of the basic knowledge, is that The basic knowledge of the synthesis of the reason why students have a sense of fear of mathematical synthesis, because usually not well summed up the experience, the law, did not give top priority to the by-pass analogy.
