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%。

解析

本题考查对文章细节信息的理解和简单的数学计算能力。解题思路是先在文章中找到关于世界海洋未知比例的关键信息，然后通过总比例（100%）减去未知比例，得出已知比例，最后与选项进行对比得出答案。

  1. 首先在文章中定位关键信息：文中提到 “It's said that 95% of the world's oceans are unknown.”，明确了世界上 95% 的海洋是未知的。
  2. 接着进行逻辑推理计算已知比例：因为海洋的总体比例为 100%，已知未知比例是 95%，那么已知比例 = $100\% - 95\% = 5\%$。
  3. 最后分析各个选项：
    • A选项 100%，与原文中海洋有未知部分不符。
    • B选项 91%，文章中未提及该比例。
    • C选项 95%，这是未知海洋的比例，并非已知比例。
    • D选项 5%，与我们计算得出的已知海洋比例一致。
