Ocean sounds may help people sleep at night, but animals in the oceans depend on 61． (they) for survival. Animals like dolphins, which rely on echolocation(回声定位) to hunt and “clicks” to communicate with their companions, 62． (be) now in trouble because ocean noise caused by humans has increased 63． (significant) since the Industrial Revolution.
Ships alone have produced low-frequency sounds along shipping routes. That's along with noise from sonar, seismic surveys, pile driving and even motorboats, which traps whales in ice by 64． (delay) their travel, according to a review 65． (publish) last week in Science.
The paper notes that climate change also threatens the soundtrack of the sea. The Great Barrier Reef has quieted over the years as it has become smaller 66． size and less habitable. Animals 67． rely on the sounds of coral reefs(珊瑚礁) to locate food and settlements may struggle to adapt. It is not just a simple 68． (assume) but a problem which deserves great attention and concern.
The authors argue that reducing the human-made noise in the ocean should be a vital component of environmental policy and they say it can 69． (do). A study conducted at the start of the COVID-19 pandemic found that a reduction in shipping traffic contributed to an average decrease of noise in waters along shipping routes near the Port of Vancouver. That was 70． piece of inspiring news.

【分析】
这是一篇说明文。人为的噪音和气候变化使得海洋生物的生存受到威胁，这一问题应该引起重视并得到解决。
61．
考查人称代词宾格。句意：海洋的声音可能有助于人们在夜间睡觉，但海洋中的动物依靠海洋的声音生存。在介词on后作宾语应用人称代词宾格。故填them。
62．
考查一般现在时和主谓一致。句意：像海豚这样依靠回声定位来捕猎和“咔嗒”声与同伴交流的动物现在陷入困境，因为自工业革命以来，人类造成的海洋噪音显著增加。根据now可知，此处表述现在的客观事实，所以应用一般现在时。主语animals为复数。故填are。
63．
考查副词。句意：像海豚这样依靠回声定位来捕猎和“咔嗒”声与同伴交流的动物现在陷入困境，因为自工业革命以来，人类造成的海洋噪音显著增加。修饰动词increased应用副词significantly表示“显著地”作状语。故填significantly。
64．
考查动名词。句意：上周发表在《科学》杂志上的一篇评论称，声纳、地震调查、打桩甚至摩托艇发出的噪音都会导致鲸鱼推迟游动，从而将鲸鱼困在冰中。在介词by后应用动名词作宾语。故填delaying。
65．
考查过去分词。句意：上周发表在《科学》杂志上的一篇评论称，声纳、地震调查、打桩甚至摩托艇发出的噪音都会导致鲸鱼推迟游动，从而将鲸鱼困在冰中。动词publish意为“发表”，和谓语之间没有连词，和逻辑主语review构成被动关系，且根据last week可知，动作已完成，所以应用过去分词作后置定语。故填published。
66．
考查固定搭配。句意：随着大堡礁变得越来越小，越来越不适合居住，它已经沉寂了多年。in size意为“在大小方面”，为固定搭配。故填in。
67．
考查定语从句。句意：依靠珊瑚礁的声音寻找食物和定居点的动物可能难以适应。在定语从句中缺少主语，且先行词为animals，所以应用关系代词which或that。故填which/that。
68．
考查名词。句意：这不仅仅是一个简单的假设，而是一个值得高度关注和关心的问题。根据“but a problem”和空前的a可知，此处应用可数名词单数assumption“假设”作表语。故填assumption。
69．
考查含情态动词的被动语态。句意：作者认为，减少海洋中人为噪声应该是环境政策的重要组成部分，他们说这是可以做到的。动词do意为“做”，it代指“reducing the human-made noise in the ocean”，和do构成被动关系。在情态动词can后应用动词原形。故填be done。
70．
考查固定搭配。句意：这是一条鼓舞人心的消息。a/one piece of意为“一条”，为固定搭配。故填a/one。
