REACHING OUT ACROSS THE SEA横跨大海
Trade and curisity have ften frmed the fundatin f mankind’s greatest achievements. T cmplete the great map f the wrld was a strng passin fr the peple f early civilisatins. Marc Pl’s tales inspired Eurpean explrers t search fr sea rutes frm west t east. Hwever，merchants and explrers frm the East set sail frm east t west many years befre Clumbus first did.
贸易和好奇心经常是人类最伟大成就的基础。完成这幅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航线。然而，东部的商人和探险家比哥伦布早很多年从东向西航行。
In ancient times，silk frm China fund its way verland t India，the Middle East，and Rme，alng what became knwn as the Silk Rad. A trading rute acrss the sea was als extended alng the casts f the Indian Ocean，centered arund Ceyln（nw Sri Lanka）. Here，merchants frm China and many ther places met t negtiate trade deals，which als led t mre awareness f each ther’s cultures. Over the centuries，further trading allwed mre explratin f the regins t the west f China，as recrded in Du Huan’s Recrd f My Travels in the eighth century.
在古代，中国的丝绸沿着丝绸之路陆路到达印度、中东和罗马。一条横跨海洋的贸易路线也沿着印度洋沿岸延伸，以锡兰（现在的斯里兰卡）为中心。在这里，来自中国和其他许多地方的商人会面，商谈贸易交易，这也使他们对彼此的文化有了更多的了解。几个世纪以来，进一步的贸易使中国西部地区得到了更多的探索，正如杜桓在我八世纪游记中所记载的那样。
Later，the Ming Dynasty further develped relatins with these regins. Between 1405 and 1433，seven large fleets sailed west n vyages f trade and explratin. These fleets were a sight t behld and were in a league f their wn at that time. Under the cmmand f Zheng He，they set sail frm the Suth China Sea acrss the Indian Ocean t the muth f the Red Sea，and then t the east cast f Africa. African ryal families sent gifts such as giraffes as gestures f friendship in return fr gld，silk，and spices. Althugh China withdrew frm further expeditins after 1433，these land and sea rutes remained active channels between ther cultures fr 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，7艘大型船队向西航行，进行贸易和勘探。这些舰队是一个看得见的景象，在当时是属于他们自己的联盟。在郑和的指挥下，他们从南中国海起航，越过印度洋到达红海入海口，再到非洲东海岸。非洲皇室送礼物，如长颈鹿作为友谊的象征，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，但这些陆路和海路在几个世纪以来一直是其他文化之间的活跃通道。
T reach ut acrss the sea remains a strng desire tday. The ancient sea rutes travelled by Zheng He are being revisited with the 21st Century Maritime Silk Rad，which is part f the Belt and Rad Initiative.
如今，跨越海洋仍然是一种强烈的愿望。由郑率领的古代海上航线，他将被重新访问，二十一世纪海上丝绸之路，这是“一带一路”倡议的一部分。
The aim f this initiative is t encurage cperatin and trade acrss the histric Silk Rad areas，and strengthen the bnds between China and the rest f the wrld. Trading has grwn greatly in recent years，and will cntinue t d s in years t cme. China has invested billins in systems and services alng these rutes，which will help t greatly develp the whle area fr the benefit f future trade and cultural exchange.
这一倡议的目的是鼓励跨越历史丝绸之路地区的合作与贸易，加强中国与世界各国的联系。近年来，贸易有了很大的增长，今后几年还将继续增长。中国在这些线路上投资了数十亿美元的系统和服务，这将有助于整个地区的大发展，有利于未来的贸易和文化交流。
China has als jined its friends acrss the sea n ther imprtant prjects. Althugh the ancient sea rutes f Zheng He have been travelled many times，there are still many ther places left t explre. In recent years，China has jined ther natins n several expeditins t explre the Arctic. Frm a scientific pint f view，there is an urgent need t study the Arctic in rder t 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，迫切需要研究北极，以便了解气候变化及其影响。
Hundreds f years n，and with the latest technlgy in hand，the need t trade and the desire t enhance relatinships will drive China t reach ut acrss the sea far int the future.
几百年过去了，在掌握最新技术的情况下，贸易的需要和增进关系的愿望将推动中国在遥远的未来跨越海洋。

When peple talk f explring the sea mre，they usually mean expliting it. Sea explratin has caused many prblems and will cntinue t cause mre.
当人们谈论更多地探索海洋时，他们通常是指开发海洋。海洋勘探造成了许多问题，并将继续造成更多的问题。
Mre explratin means mre pllutin. The Deepwater Hrizn spilled ver 200 millin gallns f il int the sea in 2010. Plastic pllutin is als bad，killing many birds and fish，and has even been fund in ur tap water.
更多的勘探意味着更多的污染。2010年，“深水地平线”号向海中泄漏了超过2亿加仑的石油。塑料污染也很严重，杀死了许多鸟类和鱼类，甚至在我们的自来水中也发现了塑料污染。
Mining fr resurces is very damaging，especially in the Arctic. Because f climate change，there is less ice nw，which means we can lk fr mre fssil fuels further nrth. But if we burn these，the ice will melt mre and this negative cycle will cntinue. Climate change is warning us that smething is very wrng.
开采资源破坏性很大，特别是在北极地区。由于气候变化，现在的冰越来越少，这意味着我们可以在更远的北方寻找更多的化石燃料。但如果我们燃烧这些，冰会融化得更多，这种负循环还会继续。气候变化正在警告我们，有些事情是非常错误的。
Overfishing is anther prblem. Whales and dlphins are als hunted fr their meat r fr s-called research. Althugh this was banned in 1982，sme cuntries are still “murdering” these intelligent creatures withut mercy. The sea is hme t life，nt human beings’ pssessins. It is huge，but it is mre sensitive than we think. If we d nt prtect it，future generatins will nt frgive us.
过度捕捞是另一个问题。鲸鱼和海豚也被猎杀以获取它们的肉或进行所谓的研究。尽管这在1982年被禁止，一些国家仍然毫不留情地“谋杀”这些聪明的生物。海洋是生命的家园，而不是人类的财产。它是巨大的，但它比我们想象的更敏感。如果我们不保护它，后代就不会原谅我们。

T truly understand ur planet，we must explre the ceans which cver mst f it. Oppnents may be cncerned，but sea explratin is imprtant fr ur future. Fr example，scientific research ships can help address imprtant issues such as climate change. We need t understand what is happening t ur planet s that we can take actin. Therefre，mre research is necessary.
为了真正了解我们的星球，我们必须探索覆盖地球大部分的海洋。反对者可能会担心，但海洋探险对我们的未来很重要。例如，科学研究船可以帮助解决气候变化等重要问题。我们需要了解我们的星球正在发生什么，这样我们才能采取行动。因此，有必要进行更多的研究。
Understanding mre abut the sea will als help us manage its resurces better. Lgging new species will imprve ur understanding f life n the earth. It may help us discver new medicines，as well as new surces f fd and energy. Accessing the deep cean may als help us t predict events such as earthquakes.
更多地了解海洋也将有助于我们更好地管理海洋资源。砍伐新物种将提高我们对地球上生命的了解。它可以帮助我们发现新的药物，以及新的食物和能源来源。进入深海也可以帮助我们预测地震等事件。
The ppulatin f the wrld is grwing and we need new resurces fr future develpment. There are prbably vast amunts f resurces under the sea and ice，nt just il and gas but als valuable minerals.
世界人口在增长，我们需要新的资源来促进未来的发展。海底和冰下可能有大量的资源，不仅仅是石油和天然气，还有宝贵的矿产。
Of curse，there are still envirnmental risks. Hwever，these shuld be balanced with ecnmic needs. Hpefully，as technlgy imprves，we may have mre ptins fr managing this balance.
当然，还有环境风险。然而，这些应该与经济需求相平衡。希望随着技术的进步，我们可以有更多的选择来管理这种平衡。
