《数学课程标准(实验稿)》指出,要强调从学生已有的生活经验出发,让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程．函数作为研究实际问题变化规律的重要数学模型,在中学数学中占有十分重要的地位．因此,函数应用题是中考命题的重点．这类问题背景丰富,又贴近生活,内容呈现形式多样,重点考查同学们的数学建模能
“Mathematics Curriculum Standards (Experimental)” points out that it is necessary to emphasize starting from the student’s existing life experience and allow students to personally experience the process of abstracting actual problems into mathematical models and explaining and applying them. As an important mathematics model to study the changing law of practical problems, functions play a very important role in middle school mathematics. Therefore, the function application question is the focus of the examination proposition. This type of problem is rich in background and close to life. The content is presented in various forms. It is important to examine the mathematic modelling ability of the students.
