- A. Put a stop to the deep sea mining projects.
- B. Solve the conflicts among deep sea miners.
- A.Cool down the craze of deep sea exploitation.
- D. Recognize the enthusiasm towards the ocean.
题目解答
答案
Cool down the craze of deep sea exploitation.
解析
步骤 1：理解背景信息
文章讨论了深海采矿的兴起及其对海洋系统稳定性的威胁。作者提到，深海采矿的兴起是基于矿物的当前货币价值，而被破坏的生态系统被认为没有货币价值。作者还提到，IUCN（国际自然保护联盟）世界保护大会采取了一些及时的行动，以帮助“钝化”对深海划分的狂热。
步骤 2：分析选项
A. Put a stop to the deep sea mining projects.（停止深海采矿项目）
B. Solve the conflicts among deep sea miners.（解决深海矿工之间的冲突）
C. Cool down the craze of deep sea exploitation.（冷却对深海开发的狂热）
D. Recognize the enthusiasm towards the ocean.（认可对海洋的热情）
步骤 3：选择正确答案
根据文章内容，作者提到IUCN世界保护大会采取了一些及时的行动，以帮助“钝化”对深海划分的狂热。因此，正确答案是C选项，即“冷却对深海开发的狂热”。
