Trade and curiosity have often formed the foundation of mankind’s greatest achievements. 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. However, merchants and explorers from the East set sail from east to west many years before Columbus first did.

Para. 1
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。

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). Here, merchants from China and many other places met to negotiate trade deals, which also led to more awareness of each other’s cultures. 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.
Para. 2
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。

Para. 3
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. 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. 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。

Para. 4
To reach out across the sea remains a strong desire today. The ancient sea routes travelled by Zheng He are being revisited with the 21st Century Maritime Silk Road, which is part of the Belt and Road Initiative. The aim of this initiative is to encourage cooperation and trade across the historic Silk Road areas, and strengthen the bonds between China and the rest of the world. Trading has grown greatly in recent years, and will continue to do so in years to come. China has invested billions in systems and services along these routes, which will help to greatly develop the whole area for the benefit of future trade and cultural exchange.
今天，跨越大海仍然是一种强烈的愿望。21世纪海上丝绸之路是“一带一路”倡议倡议的一部分，郑和旅行的古代海上航线正在被重新审视。这项倡议的目的是鼓励历史悠久的丝绸之路地区的合作和贸易，加强中国与世界其他地区之间的联系。贸易近年来大幅增长，并将在未来几年继续增长。中国在这些路线上的系统和服务投资了数十亿美元，这将有助于整个地区的巨大发展，有利于未来的贸易和文化交流。

Para. 5
China has also joined its friends across the sea on other important projects. Although the ancient sea routes of Zheng He have been travelled many times, there are still many other places left to explore. In recent years, China has joined other nations on several expeditions to explore the Arctic. From a scientific point of view, there is an urgent need to study the Arctic in order to understand climate change and its effects.
中国还与海对岸的朋友一道参与了其他重要项目。尽管郑和的古代航海路线已经走过了很多次，但仍有许多其他地方有待探索。近年来，中国与其他国家一起进行了几次北极探险。从科学的角度来看，迫切需要研究北极，以了解气候变化及其影响。

Hundreds of years on, and with the latest technology in hand, the need to trade and the desire to enhance relationships will drive China to reach out across the sea far into the future.
