Para. 1 1.Trade and curiosity have often formed the foundation of mankind’s greatest achievements. 2. To complete the great map of the world was a strong passion for the people of early civilisations. Marco Polo’s tales inspired European explorers to search for sea routes from west to east. 3. However, merchants and explorers from the East set sail from east to west many years before Columbus first did. 贸易和好奇心往往构成了人类最伟大成就的基础。绘制完成伟大的世界地图是早期文明人民的强烈热情。马可波罗的故事启发了欧洲探险家寻找从西到东的海上路线。然而，来自东方的商人和探险家比哥伦布第一次从东向西航行早了很多年。 Main idea Travel from east to west began long before Columbus. Self-learning guidance2 (3’) 1.Read para2 and translate them by yourselves loudly and fluently. 2.Mark the phrases and long &complex sentences you didn't understand. 3.Get the main idea of para2. 1. In ancient times, silk from China found its way overland to India, the Middle East, and Rome, along what became known as the Silk Road. A trading route across the sea was also extended along the coasts of the Indian Ocean, centred around Ceylon (now Sri Lanka). 2. Here, merchants from China and many other places met to negotiate trade deals, which also led to more awareness of each other’s cultures. 3.Over the centuries, further trading allowed more exploration of the regions to the west of China, as recorded in Du Huan’s Record of My Travels in the eighth century. 在古代，来自中国的丝绸通过陆路到达印度、中东和罗马，这就是后来的丝绸之路。一条横跨大海的贸易路线也沿着印度洋海岸延伸，以锡兰（现在的斯里兰卡）为中心。在这里，来自中国和许多其他地方的商人聚在一起谈判贸易协议，这也提高了他们对彼此文化的了解。几个世纪以来，进一步的贸易允许对中国西部地区进行更多的探索，正如杜环在八世纪的《我的游记》中所记录的那样。 Main idea： In ancient times, travel east to west was on the Silk Road. Self-learning guidance3 (3’) 1.Read para3 and translate them by yourselves loudly and fluently. 2.Mark the phrases and long &complex sentences you didn't understand. 3.Get the main idea of para3. 1. Later, the Ming Dynasty further developed relations with these regions. Between 1405 and 1433, seven large fleets sailed west on voyages of trade and exploration. These fleets were a sight to behold and were in a league of their own at that time. 2. Under the command of Zheng He, they set sail from the South China Sea across the Indian Ocean to the mouth of the Red Sea, and then to the east coast of Africa. African royal families sent gifts such as giraffes as gestures of friendship in return for gold, silk, and spices. 3.Although China withdrew from further expeditions after 1433, these land and sea routes remained active channels between other cultures for centuries. 后来，明朝进一步发展了与这些地区的关系。1405年至1433年间，七支大型船队向西航行，进行贸易和勘探。这些舰队是一道亮丽的风景线，在当时属于他们自己。在郑和的指挥下，他们从南中国海出发，穿过印度洋，到达红海河口，然后到达非洲东海岸。非洲王室送长颈鹿等礼物作为友谊的象征，以换取黄金、丝绸和香料。尽管中国在1433年后退出了进一步的探险，但这些陆地和海上路线在几个世纪以来一直是其他文化之间的活跃渠道。 Main idea： Zheng He’s sea voyages built relations with other countries. summary 1.form the foundation of 构成...的基础 2.a passion for... 对...酷爱 3.set sail from 从...起航 4. find one’s way to... 找到通往...的路 5. become known as 作为...而闻名 6. in return for 作为对...的回报 7.withdraw from 退出；撤回 $$
