近年来,应用题的发展由量变到质变,出现了许多情景新颖,富有时代气息,有科学依据,切合实际更贴近生活的题型.数学应用题作为高考的一道“大餐”,已成为不争的事实.它是考核阅读理解能力、信息迁移能力和数学思想发展的实际应用能力的重要形式;也是当今国际数学教育面向大众化和应用化发展的一种必然趋.而如何将一个用文字叙述的应用题根据其实际意义概括抽象为一个纯粹的数学问题,同时抓住命题中所蕴含的数学信息,恰当准确地转变为一个数学模型,则成为学生解应用题 In recent years, the development of applied questions has changed from quantitative to qualitative, and many new situations have emerged, full of contemporary flavor, scientific basis, and practical questions that are closer to life. Mathematical application questions have become indisputable as a “meal” for the college entrance examination. The facts. It is an important form of appraisal of reading comprehension ability, information transfer ability and practical application ability of mathematics development; it is also an inevitable trend of the development of international mathematics education for popularization and application. How to use a text to describe The application title summarizes the abstraction as a purely mathematical problem according to its actual meaning, and at the same time, it grasps the mathematical information contained in the proposition and transforms it into a mathematical model appropriately and accurately.
