1405年夏，中国一位最伟大的探险家郑和从太仓起锚，开启了他的首次远航。其船队有船200余艘，载着近两万八千人，在碧海上乘风破浪，场面极其壮观。规模更大的航海船队要到500年后才出现。据史料记载，郑和船队最大的船长逾140米，可知其造船技术之高超，工艺之独特。 Unit 3　Back to the past 英语　选择性必修　第三册　Y 返回导航 课文翻译 1405至1433年间，郑和代表明朝总共进行了七次航行。他的船满载瓷器、丝绸、茶叶和其他奇珍异宝作为馈赠异邦君王的礼品。船队先后对30多个国家和地区进行友好访问。他最远甚至抵达了非洲东海岸。航行时，海员们一路上记录罗盘刻度，书写航海日志，绘制海岸地图。后来这些详细的地图就成了《郑和航海图》。 郑和七次下西洋对中国及其邻国产生了深远影响。在郑和到访过的国家和地区，至今流传着有关这位伟大探险家的传说。郑和的努力有助于发展和加强中国与这些国家和地区的和睦关系，促进中国文化的对外传播，也增进中国对海外诸邦的了解。 Unit 3　Back to the past 英语　选择性必修　第三册　Y 返回导航 课文翻译 多年来，一些历史学家把这些航海记录当作传说而不予理会。后来，铁证出现了，在南京发现了一个巨大的造船厂，当年郑和的船便在此处建造。郑和的成就在今天获得广泛认可，他也作为中国最具影响力的探险家之一被世人铭记。 克里斯托弗·哥伦布 凡取得伟大发现的人，往往必须战胜重重磨难，探险家克里斯托弗·哥伦布便是如此。1451年，哥伦布生于意大利一个港口城市。少年时代他就喜爱航海，对地理表现出极大的兴趣。这些激励他开始了海员生涯。 Unit 3　Back to the past 英语　选择性必修　第三册　Y 返回导航 课文翻译 哥伦布坚持要横渡大西洋，开辟一条直通东印度群岛的航线。经过不懈的尝试，他终于获得了西班牙国王和王后的资助。1492年8月3日，他和约90名船员分乘三艘船从西班牙出发。这次航行充满了挑战：航行时间比预期的要长，食物储备不足，还有一艘船严重漏水，船上所有人都命悬一线。船上的人们都陷入了恐慌。哥伦布不理会这些挑战，凭借自己的知识和勇气，确保大家都平安越过海洋。终于，10月12日那天，有船员看到远方的陆地。哥伦布深信来到了东印度群岛，便将生活在岛上的土著人称为印地安人。然而，他们所到达的海岸其实属于加勒比海地区，而不是东印度群岛。 Unit 3　Back to the past 英语　选择性必修　第三册　Y 返回导航 课文翻译 1493至1504年间，哥伦布又先后三次出航，途中发现了更多陆地。这位伟大的探险家最大的贡献是“发现”了新大陆。他的发现激励了诸如詹姆斯·库克船长这样的探险家去探索和发现世界更广大的区域。他的航海活动开启了大航海时代的新篇章，那是一个见证许多重大地理发现的时期。同时，这个时期也实现了思想和文化的国际交流。 Unit 3　Back to the past 英语　选择性必修　第三册　Y 返回导航
