C
Glaciers, the ancient rivers of ice, are among Earth's most breathtaking(壮观的) natural wonders. However, scientists say they are now "crying". They are melting at a fast speed because of global warming.
In places like Glacier National Park in the USA, the number of large glaciers has dropped sharply over the past century. When glaciers melt, they cause serious problems. First, they add huge amounts of water to the oceans, which makes sea levels rise. This threatens coastal cities and islands. Second, many animals, like polar bears and seals(海豹), lose their hunting and living grounds. Third, glaciers are important sources of fresh water for millions of people. Their disappearance could lead to future water shortages(短缺).
These icy giants are sending us a clear message: They need help. The help they need is for us to take action against climate change by using cleaner energy and protecting our planet.

答案
1.B 2.B 3.A 4.C 5.C
解析
1. 细节理解题：根据第一段内容“They are melting at a fast speed because of global warming.”可知，冰川正面临快速融化的问题，A选项的"crying"是比喻的拟人说法，并非冰川实际面临的问题，C选项是冰川本身的属性，因此选B。
2. 细节理解题：根据第一段“They are melting at a fast speed because of global warming.”可知，冰川“哭泣”也就是加速融化的主要原因是全球变暖，因此选B。
3. 细节理解题：根据第二段“When glaciers melt, they cause serious problems. First, they add huge amounts of water to the oceans, which makes sea levels rise.”可知，冰川融化会导致海平面上升，B、C选项的描述都和原文内容不符，因此选A。
4. 细节理解题：根据第二段“Second, many animals, like polar bears and seals(海豹), lose their hunting and living grounds.”可知，北极熊这类动物会失去它们的栖息地，A、B选项描述均无原文依据，因此选C。
5. 主旨大意题：文章先介绍了冰川加速融化的现状和它带来的各类危害，最后呼吁人们采取行动应对气候变化、保护地球，也就是解释冰川面临的问题并号召人们提供帮助，A、B选项都不是文章的写作目的，因此选C。
