开放型的实际应用题形式多样,考查范围广泛,还可以与生活中的实际应用联系起来,所以在近年来的初中数学考试中很是热门。纵观近年来的中考题可以发现这些开放型的实际应用题大都与一次函数、方程、不等式相关,灵活地考察了它们的综合运用能力。本文笔者结合多年的教学经验,就一次函数与方程和不等式的应用做一分析,希望能给广大同行提供参考。 Open practical application questions in various forms, to examine a wide range, but also with the practical application of life, so in recent years, junior high school mathematics exam is very popular. Throughout the senior high school entrance examination questions in recent years, we can find that most of these open practical problems are related to the first-order functions, equations and inequalities, and they are flexible to examine their comprehensive utilization ability. In this paper, the author combined with years of teaching experience, to a function and equations and inequalities to do an analysis of the application, I hope to give reference to the general counterparts.
