有关地球的光照图的试题,是高初中地理知识结合,考察学生知识和能力的一种常见的题目。现就光照图的类型和解答技巧——六步读图法作以下说明。一、关于地球光照图的类型 1.地球侧视图。这是最常见的一种光照图,一般是北极在上,南极在下,赤道为一直线居中,地轴或竖直或倾斜,晨(昏)线以直线(有时也有弧线)形式表现出来。光照状况多以夏至、冬至和二分日3种形态表现出来,(近年亦有非二分、二至日图的出现,难度有所提高)如下:
The questions about the light map of the earth are a common topic of combining high-level geography knowledge with students’ knowledge and ability. The following is a description of the types and answers of light maps: the six-step image reading method. First, on the type of Earth’s light map 1. Earth side view. This is the most common kind of light map, usually with the North Pole at the top, the Antarctica at the bottom, the equator at the center of a straight line, the Earth’s axis vertical or inclined, and the morning (faint) line in straight lines (and sometimes arcs). The light conditions are mostly expressed in three forms: the summer solstice, winter solstice, and two-division day. (In recent years, non-dichotomous, two-to-day maps have appeared, and the difficulty has been increased.)
