近几年的高考数学试题 ,设置了一些学科内和跨学科的综合题 ,它们的新颖性、综合性 ,值得我们重视 在知识网络交汇点处设计试题、注重多学科知识的互相渗透是高考考试命题改革的一个方向 ,光学与解几的交汇综合题正是在这种背景下“闪亮登场” 由于这类题目涵盖的知识点多 ,数 In recent years, the college entrance examination mathematics test questions have set up a number of interdisciplinary and interdisciplinary comprehensive questions.
