翻译一段话
中国万里长城是世界上修建时间最长,工程量最大的冷兵器战争时代的国家军事性防御工程,凝聚着我们祖先的血汗和智慧,是中华民族的象征和骄傲.
据说,飞向太空的宇航员曾经报告说,从遥远的月球观察地球,能够辨认出的人类工程只有两个,其中一个就是中国的万里长城.雄伟的万里长城是中国古代人民创造的世界奇迹之一,也是人类文明史上的一座丰碑.根据历史记载,从战国以来,有20多个诸侯国和封建王朝修筑过长城.最早是楚国,为防御北方游牧民族或敌国,开始营建长城,随后,齐、燕、魏、赵、秦等国基于相同的目的也开始修筑自己的长城.秦统一六国后,秦始皇派著名大将蒙恬北伐匈奴,把各国长城连起来,西起临洮,东至辽东,绵延万余里,遂称万里长城,这就是“万里长城”名字的由来.但今天我们所见到的主要是明长城.
秦长城只有遗迹残存.秦始皇为了修筑长城动用了30万人,创造了人类建筑史上的奇迹.长城的修建客观上起到了防止匈奴南侵,保护中原经济文化发展的积极作用.孙中山先生曾评价：“始皇虽无道,而长城之有功于后世,实上大禹治水等”.
汉代继续对长城进行修建.从文帝到宣帝,修成了一条西起大宛贰师城,东至黑龙江北岸,全长近一万公里,古丝绸之路有一半的路程就沿着这条长城,是历史上最长的长城.到了明代,为了防御鞑靼、瓦刺族的侵扰,从没间断过长城的修建,从洪武至万历,其间经过20次大规模的修建,筑起了一条西起甘肃的嘉峪关,东到辽东虎山,全长6350公里的边墙.长城有极高的旅游观光价值和历史文化意义.现在经过精心开发修复,山海关、居庸关、八达岭、司马台、慕田峪、嘉峪关等处已成为驰名中外的旅游胜地.蹬高远眺,凭古怀幽,古战场的金戈铁马似乎就在眼前.如今,长城与埃及的金字塔,罗马的斗兽场,意大利的比萨斜塔等同被誉为世界七大奇迹,是中华民族古老文化的丰碑和智慧结晶,象征着中华民族的血脉相承和民族精神.
