Sea exploration has caused many problems and will continue to cause more. More exploration means more pollution. The Deepwater Horizon spilled② over 200 million gallons③ of oil into the sea in 2010. Plastic pollution is also bad, [1]killing many birds and fish, and has even been found in our tap water. [1]此处为现在分词短语作结果状语，表示自然而然的结果。 [第一部分　教材助读] Mining for resources is very damaging, especially in the Arctic. Because of climate change, there is less ice now, [2]which means we can look for more fossil fuels④ further north. But if we burn these, the ice will melt more and this negative cycle⑤ will continue. Climate change is warning us that something is very wrong. [2]此处为which引导非限制性定语从句，指代上文的整个句子。 [第一部分　教材助读] 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 “murdering⑥” these intelligent creatures without mercy⑦． The sea is home to⑧ life, not human beings' possessions⑨. It is huge, but it is more sensitive than we think. If we do not protect it, future generations will not forgive us. [第一部分　教材助读] Text 2 [3]To truly understand our planet, we must explore the oceans which cover most of it. Opponents⑩ may be concerned⑪， but sea exploration is important for our future. For example, scientific research ships can help address⑫ important issues such as climate change. [4]We need to understand what is happening to our planet so that we can take action⑬. Therefore, more research is necessary. [3]本句中动词不定式To truly understand our planet作目的状语；which引导定语从句，修饰先行词the oceans。 [4]本句中what引导宾语从句；so that引导目的状语从句。 [第一部分　教材助读] [5]Understanding more about the sea will also help us manage its resources better. Logging⑭ 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. Accessing⑮ the deep ocean may also help us to predict events such as earthquakes. [5]Understanding more about the sea和Logging new species均是动词-ing形式作主语。 [第一部分　教材助读] The population of the world is growing and we need new resources for future development. There are probably vast amounts of⑯ 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 options⑰ for managing this balance. [第一部分　教材助读] 文本一 当人们在谈论扩大海洋探索的时候，他们通常指的是海洋开发。海洋探索已经造成了许多问题，并且还将继续引发更多的问题。 扩大探索意味着污染加剧。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。 [第一部分　教材助读] 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，这意味着我们可以在更北的地方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，这一恶性循环将持续下去。气候变化正警告我们情况不妙。 过度捕捞是另一个问题。捕杀鲸鱼和海豚以获取它们的肉或对它们进行所谓的研究。尽管这早在1982年就被禁止了，但一些国家仍在残忍地“谋杀”这些聪明的生物。 海洋是生命的家园，而不是人类的私有财产。它广阔无垠，但比我们想象的更为敏感。如果我们不保护它，子孙后代将不会原谅我们。 [第一部分　教材助读] 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。反对者也许会担心，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像气候变化这种重要的问题。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。 [第一部分　教材助读] 深入了解海洋也将帮助我们更好地管理其资源。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，还有珍贵的矿产。 当然，环境风险仍然存在。然而，这些风险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实现这种平衡。 [第一部分　教材助读] $
