2016年全国卷数学试题与2015年相比较,体现了三个特点.第一是试题结构、题型保持相对稳定;第二是文理科的难度差距缩小,文科难度上升,理科难度有下降的趋势;第三是文科数学的难度上升,很大程度上是考查形式上的创新,这种创新主要体现在立体几何上.文科数学第11题通过截面来考查学生的空间想象力(补体),立体几何题第18 The national volume mathematics test in 2016 reflects three characteristics compared with that in 2015. The first one is the structure of test questions and the type of question remains relatively stable. The second one is that the difficulty of liberal arts and sciences narrows, the degree of liberal arts increases, and the difficulty of science decreases. The third is the difficulty of liberal arts mathematics to rise, to a large extent, to examine the formal innovation, this innovation is mainly reflected in the three-dimensional geometry .Art math eleventh problem through the cross section to examine students’ spatial imagination (complement), three-dimensional Geometry title 18th
