学习数学的过程中,所积累的知识经验经过加工,会得出有长久保存价值或基本重要性的典型结构与重要类型——模式,将其有意识地记忆下来.当遇到一个新问题时,我们辨认它属于哪一类基本模式,联想起一个已解决的问题,在记忆贮存中提取出相应的方法来加以解决,这就是模式识别的解题策略.比如同学们熟悉的轴对称最值模式(有些资料也称“将军饮马”模式)就常常出现在以下一些考题中.例1(2013·山东威海)如图1,已知 In the process of learning mathematics, the accumulated knowledge experience is processed, and the typical structure and important type - model with long-term preservation value or basic importance can be drawn and consciously memorized.When a new problem is encountered, We recognize that it belongs to a certain type of basic model, think of a problem has been solved, in memory storage to extract the corresponding method to be resolved, this is the pattern recognition problem solving strategy.For example, students are familiar with the axisymmetric most value mode (Some information, also known as “generals to drink horse ” mode) often appear in the following test questions. Example 1 (Shandong 2013 Weihai) is known
