教材 分析 本文体裁属于说明文，脉络清晰地介绍了中国从古至今的海洋探索历程。贯穿全文的是一条时间线：从早期的航海探索到明代郑和下西洋，再到现代的“一带一路”和中国海洋科考，最后表达对未来的展望。古今时间线的推进也伴随着人类逐步深化海洋探索的过程。文章第一段开宗明义，指出贸易往来和对世界的好奇心驱使着人类探索未知的世界，列举马可波罗、 哥伦布等知名西方航海家，接着话锋一转，提到更早之前东方就有向西方航行的探险活动，从而引出中国的海洋探索历史。第二段介绍了古代丝绸之路，特别是海上丝绸之路的产生与发展和对沿线地区的经贸往来和文化传播的促进作用。第二段以中国唐代杜环的《经行记》为例，展现了早期东西方的交流。第三段讲述明代郑和下西洋拓展中外交流的壮举。文中用a sight to behold、a league of their own time等词组形容郑和率领的船队， 用gestures of friendship来描述中国与非洲国家之间的友好往来，呈现当时明朝的繁荣昌盛与中国悠久的和平外交传统。第四段承接上文，指出如今的中国继续海洋探索，并介绍了“一带一路”。这段重点介绍了“21世纪海上丝绸之路”以及现代海洋贸易延续古代丝路促进沿线经贸和文化交流的作用。这突出了在全球化背景下，不断深化中国和世界其他地区的合作，推动互利共赢、经贸发展、文明交流互鉴的重要意义。第五段介绍当代中国在海洋探索领域开展的其他国际合作，以南极为例，阐释海洋科考对于研究气候变化等全球问题的重要性。第六段总结全文，展望未来——伴随着科技的进步，中国将继续开拓进取，深化海外合作。

China’s Sea Exploration
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, centered 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.

Careful reading
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.

Careful reading
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 exchange.

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 effect.
