Loggingnewspecies是動名詞，作主語。[參考譯文]文本1人們在談論擴大海洋勘探的時候，通常指的是海洋開發(fā)。海洋勘探已經(jīng)造成了許多問題，并將繼續(xù)引發(fā)更多問題。擴大勘探意味著污染加劇。2010年“深水地平線”號鉆井平臺在海中溢出了兩億多加侖的石油。塑料污染也十分嚴重，導致許多鳥類和魚類死亡，甚至在我們的自來水中也發(fā)現(xiàn)了塑料污染。資源開采極具破壞性，尤其是在北極地區(qū)。由于氣候變化，現(xiàn)在冰川減少了，這意味著我們可以在更北的地方尋找更多的化石燃料。但是，如果我們燒盡這些燃料，冰川將融化得更多，這一不良循環(huán)將持續(xù)下去。氣候變化正警告我們情況不妙。過度捕撈是另一個問題。鯨魚和海豚也遭到捕殺，成為盤中美食或用于所謂的研究。盡管早在1982年就已禁止，但有的國家仍在無情地“謀殺”這些聰明的生物。海洋是生命的家園，而不是人類的私產。海洋廣闊無垠，但比我們想象的更為敏感。如果我們不保護它，子孫后代將不會原諒我們。文本2為了真正了解我們的星球，我們必須探索覆蓋其表面大部分的海洋。反對者也許會憂心忡忡，但是海洋探索對我們的未來十分重要。例如，科學考察船可以幫助應對像氣候變化這種重要的問題。我們需要了解我們的星球正在發(fā)生什么，這樣我們才能采取行動。因此，有必要開展更多的研究。深入了解海洋也有助于我們更好地管理其資源。記載新物種將提升我們對地球上的生命的了解。這可能還會幫助我們發(fā)現(xiàn)新的藥物，以及新的食物和能源來源。深海探索還有可能會幫助我們預測地震等事件。世界人口正在不斷增長，我們需要新的資源來維系未來的發(fā)展。海洋和冰川之下可能蘊藏著大量的資源，不僅僅是石油和天然氣，還有珍貴的礦物。當然，環(huán)境風險仍然存在。但是，這些風險應該與經(jīng)濟需求相平衡。隨著技術的進步，我們有望會有更多的選擇來駕馭這一平衡。Ⅰ.核心詞匯根據(jù)語境寫出正確的單詞1．media________

(1)動名詞短語作主語往往表示經(jīng)常性、習慣性的動作，謂語動詞通常用單數(shù)形式。(2)動名詞(短語)作主語和不定式作主語一樣，也可以用it作形式主語，多見于某些形容詞及名詞之后。常見的能用于這種結構的形容詞和名詞有：good，nogood，nouse，useless等。[佳句]
