B
The United Nations decided that 2025 is the year of glacier (冰川) protection. It set March 21, 2025, as the first World Day for Glaciers. This event encouraged people to save glaciers.
What are glaciers?
You can imagine glaciers as slowly moving ice and snow on land. Over time, the snow adds up and turns into glacier ice. Glaciers have shaped mountains over the earth’s history. They are still moving and changing land in many places today.
▲
Glaciers are not just needed for the land. When glaciers melt, the nutrients (养料) from the water are good for life in rivers and oceans. In some places, glaciers provide water for people and animals. There are about 200 000 glaciers in the world, covering 10 per cent of the land. They also hold 70 per cent of the earth’s fresh water. In areas like the Himalayas, many people need glacier water to live. This water fills big rivers, such as the Indus, Ganges and Brahmaputra.
Why are glaciers disappearing (消失)?
Climate change is leading to serious problems for glaciers. Many glaciers have disappeared. The atmosphere (大气层) around the earth is like the glass of a greenhouse, letting sunlight in and keeping most heat from getting out. This makes the earth warm enough for life. But when we burn wood and coal, we produce a gas called carbon dioxide. Too much of this gas pollutes the atmosphere and causes it to keep in too much heat. As the earth’s temperature is increasing, glaciers melt faster.
The influence (影响) of glaciers disappearing.
If glaciers disappear, there will be less water for us to drink and farm, while floods may happen more often. It would also be bad for animals and plants. Mountains with glaciers are home to special ecosystems and a large number of animals. As temperatures rise and glaciers melt, they are not fit for these living things.

联合国决定将2025年定为冰川保护年。它将2025年3月21日定为首个世界冰川日。这一活动鼓励人们保护冰川。
什么是冰川？
你可以把冰川想象成陆地上缓慢移动的冰雪。随着时间的推移，积雪不断堆积，变成冰川冰。在地球的历史进程中，冰川塑造了山脉。如今，它们仍在许多地方移动并改变着陆地。
▲
冰川不仅对陆地很重要。当冰川融化时，水中的养分对河流和海洋中的生物有益。在一些地方，冰川为人类和动物提供水源。世界上大约有20万条冰川，覆盖了10%的陆地。它们还储存着地球70%的淡水。在喜马拉雅山脉等地区，许多人需要冰川水来维持生活。这些水注入了印度河、恒河和雅鲁藏布江等大河。
为什么冰川正在消失？
气候变化给冰川带来了严重的问题。许多冰川已经消失。地球周围的大气层就像温室的玻璃，让阳光照进来，同时阻止大部分热量散发出去。这使得地球的温度适宜生命生存。但是当我们燃烧木材和煤炭时，会产生一种叫做二氧化碳的气体。这种气体过多会污染大气层，导致它保留过多的热量。随着地球温度的升高，冰川融化得更快。
冰川消失的影响。
如果冰川消失，我们可供饮用和灌溉的水将会减少，而洪水可能会更频繁地发生。这对动植物也会很不利。有冰川的山脉是特殊生态系统和大量动物的家园。随着气温升高和冰川融化，这些地方将不再适合这些生物生存。
（C）4. 从第二段中我们能了解到关于冰川的什么信息？
A. 它们由冰冷的海水构成。
B. 它们在夏天会完全消失。
C. 它们移动缓慢并改变陆地。
D. 它们主要在高山山顶。
（B）5. 哪个句子可以填入空白处“▲”？
A. 冰川什么时候融化？
B. 冰川为什么重要？
C. 总共有多少条冰川？
D. 冰川会发生什么？
（D）6. 根据文章，大气层是如何处理阳光的？
A.
B.
C.
D.
（C）7. 如果冰川消失会发生什么？
A. 饮用水会更多。
B. 洪水会比以前更少。
C. 动植物会陷入困境。
D. 水会更适合灌溉。
（A）8. 这篇文章的主要目的是什么？
A. 呼吁采取行动保护冰川。
B. 记录冰川的移动。
C. 介绍一些关于冰川的事实。
D. 展示冰川是如何塑造山脉的。
