Between 1405 and 1433，seven large fleets sailed west on vo

10、yages 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 se

From a scientific point of view，there is an urgent need to study the Arctic in order to understand climate change and its effects.中国还与它的海上朋友们一道参与了其他重要项目。虽然郑和的古中国还与它的海上朋友们一道参与

18、了其他重要项目。虽然郑和的古代海路已经走了很多次，但还有很多地方有待探索。近年来，中国代海路已经走了很多次，但还有很多地方有待探索。近年来，中国与其他国家一道进行了几次北极探险。从科学的角度来看，迫切需与其他国家一道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，以便了解气候变化及其影响。要研究北极，以便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 Chi

The Deepwater Horizon spilled over 200 million gallons of oil into the sea in 2010. Plastic pollution is also bad, killing

21、 many birds and fish, and has even been found in our tap water.扩大勘探意味着污染加刷。扩大勘探意味着污染加刷。2010年年“深水地平线深水地平线”号钻井平台在海号钻井平台在海中溢出了两亿多加仑的石油。塑料污染也十分严重，导致许多鸟中溢出了两亿多加仑的石油。塑料污染也十分严重，导致许多鸟类和鱼类死亡甚至在我们的自来水中也发现了塑料污染。类和鱼类死亡甚至在我们的自来水中也发现了塑料污染。 Mining for resources is very damaging, especially in the Arctic. Because o

22、f climate change, there is less ice now, which means we can look for more fossil fuels further north. But if we burn these, the ice will melt more and this negative cycle will continue. Climate change is warning us that something is very wrong.资源开采极具破坏性，尤其是在北极地区。由于气候变化，现在资源开采极具破坏性，尤其是在北极地区。由于气候变化，现在
