函数是高中数学中起连接和支撑作用的主干知识,纵观近几年高考函数试题,随着新课改的发展,函数类型的考题也随之发生了一定的变化,命题方向正朝着网络型发展。即以函数知识为依托,在数列、方程、不等式等知识交汇点上设计的试题,构筑成知识网络型代数推理题,题型设计新颖,别具一格,知识浑然一体,反映了知识间的内在联系,它把中学数学各个分支紧紧地联系在一起,一些常见的解题技巧和思想方法都得到了比较充分的体现,较好地体现了知识的整体性和综合性,突出对问题的方法及解决问题能力的考查,在高考试题中出现的频率相当高,占据着令人瞩目的地位。
Function is the backbone of high school mathematics plays the role of connection and support of the backbone, taking a look at the entrance examination questions in recent years, with the development of the new curriculum reform, the type of function tests also followed certain changes, the proposition direction is toward the network Development. That is to say, based on the functional knowledge, questions designed on the intersections of series, equations, inequalities and other knowledge are constructed into knowledge network algebraic inference questions. The questions are novel in design and distinctive in style. The knowledge is integrated with each other, reflecting the intrinsic connection between knowledge, It links all branches of high school mathematics closely, and some common problem-solving skills and thinking methods have been more fully reflected, a better embodiment of the integrity and comprehensiveness of knowledge, highlighting the methods and solutions to the problems Examination of the problem ability, the frequency of the college entrance examination appeared in a very high frequency, occupy an eye-catching position.
