13、he Moon, and even of Venus and Mars, than we do of Earths own sea bed.1Among these is the Esmeralda.为介词短语位于句首构成的完全倒装句。Given our limited knowledge， it is perhaps no surprise that exploration of the oceans continues to lead to discoveries in various scientific fields.2 As with the discovery of the Esm

14、eralda, many archaeological finds are made in shallow waters near the coast.These may sometimes include whole cities buried beneath the waves.One such find is the ancient Roman city of Nepolis, discovered off the coast of Tunisia.Believed to have been buried underwater by a tsunami in the fourth cen

15、tury AD, the ruins of Nepolis are almost 2，000 years old.The remaining streets and buildings offer a window into a fascinating period in our history.However, we are only beginning to overcome the challenges of pressure, darkness and extreme cold at vast depths.Fragments of the past lying deep beneat

18、yes that can look upwards through its transparent forehead.In the very deepest ocean trenches that are more than 8，000 metres below the surface, the pressure is equivalent to 50 aeroplanes stacked one on top of another.4 Yet there is still life to be found, even around the deepsea volcanic openings.

19、These discoveries all help us understand the capacity for life on our planet, even in the most extreme circumstances.3where和that都引导定语从句；as if引导表语从句。4that引导定语从句；stacked one.是过去分词短语作后置定语。Furthermore, the oceans are a valuable source of natural resources, some of which are completely new to us. 5 Most

20、notable of these is Chinas discovery of an icelike substance, known as “fire ice”， under the South China Sea.In addition, Chinas underwater vessels, such as the Jiaolong and Shenhai Yongshi, have been exploring waters at depths of thousands of metres.The Jiaolong even holds the record for the deepes

23、coming part of a global mission to open up our planets final frontier.Humankind is entering a new age of oceanic discovery, and the world beneath the waves may one day be almost as familiar to us as the land we walk upon today.译文参考潜入海底据估计，在全球海洋中大约有三百万艘沉船。所有这些都代表了几个世纪以来探索地球最遥远角落的尝试。其中包括埃斯梅拉达，欧洲人探索亚洲时

24、代最早的沉船。今天，在埃斯梅拉达号启航约500年后，我们的星球上几乎没有未开发的土地。我们有更详细的月球，甚至金星和火星的地图，比我们地球自己的海床(地图)还要详细。鉴于我们的知识有限，对海洋的探索继续导致各个科学领域的发现也许并不令人惊讶。就像埃斯梅拉达号的发现一样，许多考古发现都是在海岸附近的浅水区进行的。这些可能有时包括埋在海浪下面的整个城市。其中一个发现就是古罗马城市奈阿波利斯，它是在突尼斯海岸发现的。人们认为在公元4世纪的一场海啸中被埋在水下的，奈阿波利斯的废墟已有近2 000年的历史。遗留的街道和建筑物提供了一扇通往我们历史上一个迷人的时期的窗户。然而，我们才刚刚开始克服巨大深度的

25、压力、黑暗和极度寒冷的挑战。过去的碎片深深地埋在海洋的下面，仍在等待被发现。惊人的生物学发现也正在进行中。海洋的暗区可能包含多达90%的地球上的鱼类。在这些水深超过200米的光线无法照射到的水域，有很多非凡的生物，它们看起来就像是直接从科幻小说中出来的。想象一下，骨白色珊瑚在海洋表面下方6 000米处，以每年只有一到两毫米的速度生长。其中一些可能有4 000岁。在这些黑暗的深处游泳的是管眼鱼，它是一种奇怪的鱼，眼睛可以透过透明的额头向上看。在海面下8 000多米的最深的海沟里，压力相当于50架飞机层层叠加。然而，即使在深海火山口周围，仍有生命可寻。这些发现都有助于我们理解我们星球上的生命能力，

26、即使在最极端的情况下也是如此。此外，海洋是宝贵自然资源的来源，他们中的一些对我们来说是全新的。最值得一提的是中国在南海下发现了一种类似冰的物质，被称为“可燃冰”。此外， “蛟龙”号、“神海勇士”号等中国水下船只也一直在数千米深的海域进行探测。“蛟龙”号甚至保持着载人潜艇最深潜水的纪录，7 062米，这使中国与世界顶级海洋探险者并列。这些船进行的研究让科学家们更好地了解海底是如何形成的，并帮助识别深海钻探的区域，将深海探索带入一个全新的时代。因为是一个完全黑暗、巨大压力和强烈寒冷的恶劣环境，海洋深处长期以来一直是人类探索无法企及的。但是，通过更密切的国际科学、经济和文化合作，我们都正在成为开辟我们星球最后边界的全球使命的一部分。人类正在进入一个海洋发现的新时代，也许有一天海浪下面的世界对我们来说就像今天走在陆地上一样熟悉。
