Ⅱ.原文释译
Text 1
When people talk of exploring the sea more，they usually mean exploiting it. Sea exploration has caused many problems and will continue to cause more.
More exploration means more pollution.The Deepwater Horizon spilled over 200 million gallons of oil into the sea in 2010.Plastic pollution is also bad，killing many birds and fish，and has even been found in our tap water.
Mining for resources is very damaging，especially in the Arctic. Because of 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.
Overfishing is another problem.Whales and dolphins are also hunted for their meat or for so-called research. Although this was banned in 1982，some countries are still “murdering” these intelligent creatures without mercy.
The sea is home to life，not human beings' possessions.It is huge，but it is more sensitive than we think.If we do not protect it，future generations will not forgive us.
Text 2
To truly understand our planet，we must explore the oceans which cover most of it.Opponents may be concerned，but sea exploration is important for our future.For example，scientific research ships can help address important issues such as climate change.We need to understand what is happening to our planet so that we can take action.Therefore，more research is necessary.
Understanding more about the sea will also help us manage its resources better.Logging new species will improve our understanding of life on the earth.It may help us discover new medicines，as well as new sources of food and energy.Accessing the deep ocean may also help us to predict events such as earthquakes.
The population of the world is growing and we need new resources for future development.There are probably vast amounts of resources under the sea and ice，not just oil and gas but also valuable minerals.
Of course，there are still environmental risks.However，these should be balanced with economic needs.Hopefully，as technology improves，we may have more options for managing this balance.
文本一
人们在谈到加大海洋勘探的时候，他们通常指的是海洋开发。海洋勘探已经造成了许多问题，并将继续引发更多问题。
加大勘探意味着污染加剧。2010年，“深水地平线”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，导致许多鸟类和鱼类死亡，甚至在我们的自来水中也发现了塑料污染。
资源开采极具破坏性，尤其是在北极地区。由于气候变化，现在冰川减少了，这意味着我们可以向北深入寻找更多的化石燃料。但是，如果我们烧尽这些燃料，冰川将融化得更多，这种负循环将持续下去。气候变化正在警告我们，有些事情大错特错。
过度捕捞是另一个问题。鲸鱼和海豚也遭到捕杀，成为盘中美食或用于所谓的研究。尽管这在1982年就已被禁止，但有的国家仍在无情地“谋杀”这些聪明的生物。
海洋是生命的家园，而不是人类的私产。海洋虽然广袤，但远比我们想象的敏感。如果我们不保护海洋，子孙后代将不会原谅我们。
文本二
为了真正了解我们的星球，我们必须探索覆盖其表面大部分的海洋。反对者也许会忧心忡忡，但是海洋探索对我们的未来十分重要。例如，科学考察船可以帮助应对诸如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，有必要开展更多的研究。
深入了解海洋也将有助于我们更好地管理海洋资源。记载新物种将增进我们对地球上生命的了解。这可能还会帮助我们发现新的药物，以及新的食物和能源来源。深海探索还有可能会帮助我们预测地震等事件。
世界人口正在不断增长，我们需要新的资源来维系未来的发展。海洋和冰川之下可能蕴藏着大量的资源，不仅有石油和天然气，还有珍贵的矿物。
当然，环境风险仍然存在。但是，这些风险应该与经济需求相平衡。随着技术的进步，我们有望会有更多的选择来驾驭这种平衡。
◆精学表达
Ⅰ.文本特征
1.该文本是一篇议论文，文章为我们呈现了关于海洋探索的两种截然不同的观点：一种观点认为海洋探索危害极大；另一种观点认为海洋探索有很大的益处。
2.议论文多是呈现某种观点(如句 )，因此，为了使读者信服，作者通过摆事实、讲道理、辨是非等方法来论证其观点，支持或否定某种主张(如句 )。
Ⅱ.语言特色
1.词汇运用
句 和句 分别使用了exploiting和murdering，准确表达了作者对探索海洋的强烈反对。
2.逻辑衔接
Text 1中使用了连词(短语)Because of、But、Although等，使论点的呈现有理有据，更具说服力；Text 2中Therefore、Of course、Hopefully等过渡词语的使用使文章结构清晰、衔接紧密、自然流畅。
