综观近几年各地课改实验区的中考数学试卷,对三种视图的考查呈加强之势.现择要列举数例,供同学们参考.一、从立体图形到三种视图例1(2007年云南省昆明市)如图1所示是由几个小正方体组成的一个几何体,这个几何体的左视图是( ). Looking at the mathematics examination papers in the experimental reform areas in various regions in recent years, the examination of the three views has been strengthened. Now we have to list a few examples for the students to refer to. First, from the three-dimensional graphics to three views Example 1 (2007 In Kunming, Yunnan Province, as shown in Figure 1 is a geometry consisting of several small cubes. The left view of this geometry is ().
