51. What does Greenpeace's study find about krill fishing?
- A. It caused a great many penguins and whales to migrate.
- B. It was depriving penguins and whales of their habitats.
- C. It was carried out too close to the habitats of penguins and whales.
- D. It posed an unprecedented threat to the wildlife around Antarctica.
答案：C
答案句：The study by Greenpeace analysed the movements of krill fishing vessels in the region and found they were increasingly operating “in the immediate vicinity of penguin colonies and whale-feeding grounds”.
参考译文：绿色和平组织的这项研究分析了该地区磷虾捕捞船的动向，发现它们越来越多地在“企鹅栖息地和鲸鱼觅食地附近”作业。
定位线索：题干“Greenpeace's study find”→答案句“The study by Greenpeace...found”；文中“in the immediate vicinity of penguin colonies and whale-feeding grounds”对应选项C“too close to the habitats of penguins and whales”。
解析：题干问绿色和平组织的研究发现，答案句直接指出捕捞船“越来越多地在企鹅栖息地和鲸鱼觅食地附近作业”，即选项C的“离企鹅和鲸鱼的栖息地太近”。选项A“导致大量企鹅和鲸鱼迁移”无中生有，文中未提及迁移；选项B“剥夺栖息地”程度过重，文中只说“附近作业”；选项D“前所未有的威胁”范围扩大，文中只说“日益临近”，未提“前所未有”。
53. What is Greenpeace's recommendation to the krill industry?
- A. Opting to operate away from the suggested conservation areas.
- B. Volunteering to protect the endangered species in the Antarctic.
- C. Refraining from krill fishing throughout the breeding season.
- D. Showing its sense of responsibility by leading the global campaign.
答案：A
答案句：Frida Bengtsson from Greenpeace's Protect the Antarctic campaign said: “If the krill industry wants to show it's a responsible player, then it should be voluntarily getting out of any area which is being proposed as an ocean sanctuary, and should instead be backing the protection of these huge tracts of the Antarctic.”
参考译文：绿色和平组织“保护南极”活动的弗里达·本特松表示：“如果磷虾产业想表明自己是负责任的参与者，那么它应该自愿退出任何被提议为海洋保护区的区域，而应该支持保护这些广袤的南极海域。”
定位线索：题干“Greenpeace's recommendation to the krill industry”→答案句“Greenpeace's...said”；文中“voluntarily getting out of any area which is being proposed as an ocean sanctuary”对应选项A“Opting to operate away from the suggested conservation areas”。
解析：题干问绿色和平组织对磷虾产业的建议，答案句中本特松明确说“应该自愿退出任何被提议为海洋保护区的区域”，即选项A“选择在建议的保护区之外作业”。选项B“自愿保护南极濒危物种”偷换概念，文中说的是退出保护区而非保护物种；选项C“在整个繁殖季节不捕捞”无中生有，文中未提繁殖季节；选项D“通过领导全球运动显示责任感”偷换概念，文中说“支持保护”而非“领导运动”。
54. What did CCAMLR aim to do according to its science manager?
- A. Raise public awareness of the vulnerability of Antarctic species.
- B. Ban all commercial fishing operations in the Southern Ocean.
- C. Keep the penguin colonies from all fishing interference.
- D. Sustain fishing without damaging the Antarctic ecosystem.
答案：D
答案句：Keith Reid, a science manager at CCAMLR, said that the organisation sought “a balance between protection, conservation and sustainable fishing in the Southern Ocean.”
参考译文：CCAMLR的科学经理基思·里德表示，该组织寻求“在南大洋的保护、养护和可持续捕捞之间取得平衡”。
定位线索：题干“CCAMLR aim to do according to its science manager”→答案句“Keith Reid...said that the organisation sought”；文中“a balance between protection, conservation and sustainable fishing”对应选项D“Sustain fishing without damaging the Antarctic ecosystem”。
解析：题干问CCAMLR的目标，答案句指出该组织寻求“保护、养护和可持续捕捞之间的平衡”，即选项D“在不损害南极生态系统的情况下维持捕捞”。选项A“提高公众对南极物种脆弱性的认识”无中生有，文中未提公众意识；选项B“禁止南大洋所有商业捕捞”与原文“可持续捕捞”矛盾；选项C“使企鹅栖息地免受所有捕捞干扰”程度过重，原文只说“平衡”，未说完全禁止。
55. How does CCAMLR define its role in the conservation of the Antarctic environment?
- A. A coordinator in policy discussions.
- B. An authority on big data analysis.
- C. A provider of the needed expertise.
- D. An initiator of marine sanctuaries.
答案：C
答案句：“Our long-term operation in the region depends on a healthy and thriving Antarctic marine ecosystem, which is why we have always had an open dialogue with the environmental non-governmental organisations. We strongly intend to continue this dialogue, including talks with Greenpeace, to discuss improvements based on the latest scientific data. We are not the ones to decide on the establishment of marine protected areas, but we hope to contribute positively with our knowledge and experience.”
参考译文：“我们在该地区的长期运营依赖于健康繁荣的南极海洋生态系统，这就是为什么我们一直与环境非政府组织保持开放对话。我们强烈打算继续这种对话，包括与绿色和平组织的会谈，以根据最新科学数据讨论改进措施。我们不是决定建立海洋保护区的人，但我们希望用我们的知识和经验做出积极贡献。”
定位线索：题干“CCAMLR define its role”→答案句“We are not the ones to decide...but we hope to contribute positively with our knowledge and experience”；文中“contribute positively with our knowledge and experience”对应选项C“A provider of the needed expertise”。
解析：题干问CCAMLR如何定义其在南极环境保护中的角色，答案句明确说“我们不是决定建立海洋保护区的人，但我们希望用我们的知识和经验做出积极贡献”，即选项C“所需专业知识的提供者”。选项A“政策讨论的协调者”偷换概念，文中说“参与讨论”而非“协调”；选项B“大数据分析的权威”无中生有，文中未提数据分析；选项D“海洋保护区的发起者”与原文“不是决定建立保护区的人”直接矛盾。
