浙江省一些地区的中学地理教师,曾经就东西方向问题展开热烈的争论。彼此观点不同,而又不能互相说服。别的地区也有类似的情况。具体的问题是这样的: 假如在北纬40°的纬线上,有A、B两点,分别位于日界线(经度180°) 的两侧;它们的经度分别是东经170°和西经170°。问:B点位于A点的东方还是西方?我们认为,这个问题不应该简单地用“东方”或“西方”来回答,而应该进行具体的分析。
Teachers of high school geography in some areas of Zhejiang province have had heated debates over the direction of the east-west direction. They have different opinions from each other and cannot convince each other. There are similar situations in other regions. The specific question is this: If we are on latitude 40 degrees north latitude, there are two points, A and B, on either side of the date line (longitude 180 degrees); their longitudes are 170 degrees east longitude and 170 degrees west longitude, respectively. Q: Does the point B lie in the east of point A or in the west? We believe that this issue should not be simply answered with “Eastern” or “Western” but should be analyzed concretely.
