答案与题解:
1. C 短文第一段的第二、第三句提供了答案。
2. A 文章第二段的第二句说,科学家正在研制一艘可将研究人员带到6,500米深处的潜水装置,而它将替代 Alvin,因为 Alvin 只能潜到4,500米深处。A 不是事实,所以是正确选择。
3. C 本文讨论探索海底世界的潜水装置,所以“充满神秘色彩的世界”指的就是海洋。
4. D 第四段的头三个句子告诉我们,HOV 和 Alvin 在体积上和容量上相似。所以 D 是正确选择。
5. D 第四段最后两句告诉我们,Alvin 只有三个窗户,而 HOV 有五个。最后一段告诉我们,两艘潜水装置的上下活动速度和行进速度有所差别。所以 D 是正确选择。
