在数学的题海中,有一类题,为了考查学生分析问题、识别问题、解决问题的能力,常通过“包装”、“遮隐”等手法,将问题的本质隐藏,而呈现出非本质的表象.如果不能看清问题的本质,一味地按原题的表象去求解,会使问题解答变得复杂困难.若能认真分析问题的条件和结论,揭去问题的表面包装,拨开遮眼的那片浮云,抓住问题的实质,常可使问题迎刃而解,触类旁通.最近调研活动中两道试题的求解过程,让人感触 In mathematics, there is a class of questions. In order to examine students’ abilities to analyze, identify and solve problems, they usually hide the essence of the problem by means of “packaging ” and “obscuring ” If you can not see the nature of the problem, blindly according to the appearance of the original title to solve, will make the problem complex and difficult to answer.If you can seriously analyze the conditions and conclusions of the problem, remove the problem surface packaging, dial Open the cover of the piece of clouds, grasping the essence of the problem, often make the problem be solved, the analogy bypassed .Recently research activities in the two questions in the process of solving people feel
