基于我国国情，高考仍然是选拔人才的重要方式。函数作为中学数学课程的一条主线，它的思想贯穿高中数学的始终。函数历年来都是高考数学试卷命题的重点和热点，在历年高考数学试卷中占有很大的比例。因此，对高考数学试卷函数的研究显得非常重要。本论文对1978-2015年的高考数学全国卷函数部分进行了研究，通过列表直观体现试题，从高考函数所考查题型以及所占分值比例、高考函数所考查的考点、高考函数与其它数学知识点的交汇考查这三个方面进行了全面的分析和总结。然后，对函数未来的命题趋势进行了预测。最后，得出了结论并且对函数教学给出了几点建议。便于广大师生更好的了解高考函数考查的题型、分值比例、考点知识以及它与其它数学知识点的联系，也使得广大师生了解了高考函数这么多年来的演变过程以及考查趋势。有助于教师指导学生更好的学习和复习，也帮助高中学生正确认识函数知识，可以在教学和学习中起到很好的效果。

Based on the situation of our country, the college entrance examination is still an important way to select talents. Function as a main line of senior high school mathematics curriculum, its thought runs through the senior high school mathematics. Function is a key and hot topic of college entrance examination papers over the years, occupies a large proportion in the calendar year in the college entrance examination papers. Therefore, it is very important to study the function of mathematics examination papers of college entrance examination . In this paper, 1978-2015 years of college entrance examination of the national volume function part of the study, The list is intuitionistic reflect questions from college entrance examination function test questions and the score proportion, college entrance examination function of the test sites, the college entrance examination function and other mathematical knowledge interchange to examine the three aspects were comprehensively analyzed and summarized. Then, the future tendency of the function is predicted. Finally, the conclusion is drawn and some suggestions are given for the function of the college entrance examination. For teachers and students to better understanding of function examination questions, score, test knowledge and other knowledge points of contact, and also makes the teachers and students understand the evolution process of the college entrance examination for so many years, as well as the research trend. Help the teachers to guide the students to better learn and review, also to help high school students to a correct understanding of the function of knowledge, can play a very good effect in teaching and learning.
