时文阅读 21 March 2025 is the first World Day for Glaciers (冰川). It was announced by the United Nations along with the International Year of Glaciers 2025. The aim is to encourage everyone to protect glaciers. They are important for sustaining life on earth now and for future generations. A glacier is made up of ice and snow that slowly flows over land. As snow continues to pile up over many years, it finally becomes a large mass of snow that starts changing into glacier ice. Throughout Earth’s history, glaciers have shaped mountains and valleys. They are still flowing and shaping landscapes in many places today. However, glaciers don’t just affect the land. When glaciers melt, they let out nutrients (营养物质) into lakes, rivers, and oceans. These nutrients can help phytoplankton, which is a tiny plant that forms the basis of aquatic food-chains (水生食物链), grow. As glaciers melt, they also provide habitats (栖息地) for plants and animals near streams. This shows that glaciers indirectly affect wildlife and fishing areas. In some areas, glaciers provide water for both people and animals. About 10 percent of the world’s land has around 200,000 glaciers, which hold about 70 percent of Earth’s fresh water, according to the UN. In the Himalayas, Karakoram, and Hindu Kush mountains, millions of people depend on the 90,000 glaciers for water. These glaciers form the headwaters (源头) of the Indus, Ganges, and Brahmaputra rivers. Climate change is having a severe effect on glaciers across the globe, and many glaciers have disappeared completely. For example, Colombia has seen 90 percent of its glacier area disappear since the mid-19th century, as shown in a 2025 UN report on global water development. The report also warns that with a temperature increase of 1.5 to 4 degrees Celsius, glaciers could lose between 26 to 41 percent of their mass (体量) from 2015 levels by 2100. 1.

B 5. D 【解析】 【导语】本文是说明文，主要介绍了冰川的形成、对地球生态和人类的重要作用，以及气候变化对冰川的严重影响，呼吁人们保护冰川。 【1题详解】 推理判断题。根据第一段“21 March 2025 is the first World Day for Glaciers ... The aim is to encourage everyone to protect glaciers. They are important for sustaining life on earth now and for future generations.”可知，第一段通过介绍首个世界冰川日，引出冰川保护这一核心话题。故选B。 【2题详解】 主旨大意题。第三段主要讲述了冰川融化时会向水体释放营养物质，促进浮游植物生长，同时为动植物提供栖息地，间接影响野生生物和渔业区域，核心是冰川融化对水生生态系统的影响。故选A。 【3题详解】 细节理解题。根据第四段“In the Himalayas, Karakoram, and Hindu Kush mountains, millions of people depend on the 90,000 glaciers for water.”可知，喜马拉雅山脉地区的人口严重依赖冰川供水。故选C。 【4题详解】 推理判断题。文章前文介绍了冰川的重要性，最后一段重点阐述了气候变化对冰川的严重破坏，按照逻辑，接下来最可能讨论全球保护冰川的具体措施，以呼应开篇“鼓励大家保护冰川”的目的。故选B。 【5题详解】 最佳标题题。文章全面介绍了冰川的形成、对地球生命的关键作用，以及其在气候变化下的濒危现状，既体现了冰川的“vital（至关重要）”，也点明了其“endangered（濒危）”的处境。故选D。 第1页/共1页 学科网（北京）股份有限公司 $
