应用问题已成为中考命题的热点之一.解决这类问题的关键是:认真读懂与领会题意,分清有关数量之间的关系,特别是相等或不等关系;准确地构建数学模型,把实际问题抽象为数学问题,以求得问题的解决.本文就初中数学中常见的类型,结合2001年全国各地中考试题进行举例说明,供中考复习时参考. Application problems have become one of the hot spots in the examination topic. The key to solving such problems is to carefully read and understand the meaning of the questions, to clarify the relationship between the relevant numbers, especially the equal or inequality relations; to accurately construct mathematical models, The actual problem is abstracted as a mathematics problem, in order to solve the problem. This article is an example of common types in junior high school mathematics, combined with the 2001 national exam questions throughout the country for reference in the review.
