在漫长的岁月中,人类对自己生存的空间产生过各种遐想。大地有尽头吗?它是方的还是圆的?为什么日、月、星辰总是东升西落?为什么会有四季变化等等。从1492年,哥伦布首航发现美洲大陆开始,人类进入了地球地理发现的时代,这个阶段持续了400年。到20世纪初期,地球上的所有地方都被绘制在地图上,其中有3个地点虽然被人所知,但没有人去过。它们就是被称为极地的“北极”“南极”和地球上的最高点——珠穆朗玛峰(以下简称珠峰)。 In the long years, human beings have had various reveries in their own living space. Is the earth an end? Is it square or round? Why day, month, stars are always rising? Why there are seasons change and so on. From 1492, when Columbus’ maiden voyage discovered the beginning of the American continent, mankind entered an era of geo-discovery of the earth, which lasted for 400 years. By the early twentieth century, all the places on earth were drawn on the map, of which three were known but no one was there. They are called “Polar” “North Pole ” “Antarctic ” and the highest point on Earth - Mount Everest (hereinafter referred to Everest).
