近几年中考数学试题中,出现了涉及了物理、化学、地理、生物、体育等学科知识的综合试题.这类问题能培养我们用数学眼光去研究其他学科的能力,体会数学的价值.解这类问题时,首先要搞清楚它与哪类学科、哪种问题相关,了解问题在相关学科中的特征,再结合数学知识,构建数学模型,加以解决. In recent years, there have been comprehensive examination questions involving physical, chemical, geographical, biological, and sports subjects in the mathematics test of the senior high school entrance examination. Such problems can cultivate our ability to use mathematics to study other disciplines, and to understand the value of mathematics. In this type of problem, it is first necessary to find out which type of discipline it is related to, which kind of problem, to understand the characteristics of the problem in the relevant disciplines, and then combine mathematics knowledge to build a mathematical model to solve it.
