第二节 请认真阅读下面短文,从短文后所给的六个选项中选出五个可以填入空白处的最佳选项。
(2025·盐城一模改编) The UN has announced 2025 as the year of the glacier(冰川). It has also set March 21, 2025 as the first World Day for Glaciers. 41. They are important for life in the future.
Glaciers are made of ice and snow that slowly move over land. Over time, layers(层) of snow build up and turn into glacier ice. Glaciers have shaped mountains over earth's history. 42. But glaciers don't just affect the land. When glaciers melt(融化), they provide nutrients(养分) for lakes, rivers and oceans. 43. As glaciers melt, they also create homes for plants and animals along streams.
44. The UN said that about 10 per cent of the world's land is covered by around 200,000 glaciers, storing about 70 per cent of earth's fresh water. In places like the Himalayas, Karakoram and Hindu Kush mountains, millions of people depend on glaciers for water. These glaciers feed big rivers like the Indus, Ganges and Brahmaputra.
45. Many glaciers have disappeared. For example, Colombia has lost 90 per cent of its glaciers since the mid-19th century. If temperatures rise by 1.5°C to 4°C, glaciers could lose much of them by 2100.
If snow and ice in mountain areas continue to disappear, there will be less water for drinking and farming and more pressure on local ecosystems. Floods will also be more dangerous because of growing glacial lakes.
A. The goal is to support everyone to help protect glaciers.
B. Most of the world's glaciers are in the polar regions(极地地区).
C. However, climate change is causing serious problems for glaciers.
D. They are still moving and changing landscapes in many places today.
E. These nutrients help create the base of the food chain in oceans and rivers.
F. In some areas, glaciers are important water sources(资源) for people and wildlife.
