一起去探险吧!你走得越远,世界就越大。远古时,人类只能各自生活在一个狭小、独立的区域里,互不相通。是一个又一个的张骞、郑和、麦哲伦、哥伦布、利文斯顿们作为先导官,使人类的足迹越走越远,使不同国家、不同世界的人们联结起来,使人类生活的空间变大。如今,地球就好像一个小村庄,发达的商业贸易和广泛的分工合作,使我们获得无数的便利。但未知的世界仍然很广大,等待着新的勇者去开辟。 Explore together! The farther you go, the bigger the world is. In ancient times, humans could only live in a small, independent area independently of each other. One after another, Zhang Qian, Zheng He, Magellan, Columbus and Livingston, as pioneering leaders, have moved mankind’s footprint further and further extended the space for humankind by linking people from different countries and worlds. Today, the Earth is like a small village. The developed commerce and trade and the extensive division of labor give us countless conveniences. But the unknown world is still vast, waiting for the new brave to open up.
