题目解答

答案

根据题目要求，我们需要找出我们目前已知世界海洋的比例。

1. 定位关键信息：
在文章的第三段中，有这样一句话：“It's said that 95% of the world's oceans are unknown.”（据说世界上 95% 的海洋是未知的。）

2. 逻辑推理：

  • 题目问的是我们“只了解（only know）”多少比例的海洋。
  • 既然 95% 的海洋是“未知（unknown）”的，那么剩下的部分就是我们已知（known）的。
  • 计算已知比例：100%（总海洋） - 95%（未知海洋） = 5%（已知海洋）。

3. 分析选项：

  • A. 100%：与原文不符。
  • B. 91%：文中未提及。
  • C. 95%：这是未知的比例，而不是已知的比例。
  • D. 5%：符合我们的计算结果，即我们只了解 5% 的世界海洋。

因此，正确答案是 D. 5%。
