在一些同学的眼中,中考数学试卷中的压轴题,尤其是动态类压轴题就像神秘的珠穆朗玛峰那般云遮雾绕、高不可攀.其实云遮雾绕是假象,高不可攀非实情,这类试题终端虽高起点却低,图虽有动关系却静.只要我们循题阶而渐进,善联想且勇尝试,就可如拨云见日般洞察其妙机,把握其精微. In the eyes of some classmates, the title question in the math test of the senior high school entrance examination, especially the dynamic class title question, is like the mysterious Everest cloud covering the fog and being unattainable. In fact, the cloud obscuring is an illusion, and it is highly impractical. Although the terminal of such test items is high starting point but low, the figure is dynamic but static. As long as we gradually follow the order of the title, make good associations and brave attempts, we can get insight into its good machine and grasp its subtleties.
