Glaciers (冰川) are formed in areas of high snowfall in winter and cool temperatures in summer. They can come in different shapes and sizes. Some glaciers are small and they may only be a few metres wide. Some glaciers are large, and they are over hundreds of thousands of kilometres.
About 10% of the world's land is covered by such different sizes of glaciers. They serve as natural reservoirs (水库) because about 75% of all the fresh water in the world is kept in glaciers. That's why glaciers are quite important.
Now some glaciers are disappearing because of global (全球的) warming. As the Earth becomes warmer, glaciers melt quickly. Scientists believe that it will lead to serious results in the near future.
There will be more earthquakes. Large glaciers stop small earthquakes because the plates can't move much under these huge objects. In Southeast Alaska, some glaciers are gone, and the land is lifted. So the plates can move more quickly, and this leads to more earthquakes there.
Volcanoes (火山) will become “hot” again. Volcanoes are waking up because of the disappearing glaciers. Even volcanoes that weren't lively have broken out several times in recent years. Scientists said that the glaciers have something to do with it. The volcanoes will become “hot” again after the glaciers get thin.
People, animals and plants are in danger. Coral (珊瑚) grows in salt water. The more glaciers melt, the more fresh water there will be, and it is not good for coral. People, animals and plants need fresh water from glaciers to live. They will be in danger if too much fresh water goes into the sea.
Something must be done. Many people are now living a green life which is a way of living with less carbon dioxide (CO₂). For example, they prefer to take public transportation and use both sides of the paper. These are helpful in slowing down global warming. With little effort and not much money, most of us can make a difference.

答案
【文章大意】本文是一篇说明文。文章主要介绍了冰川的形成、重要性、全球变暖导致的冰川消失及其带来的严重后果以及人们为减缓全球变暖所采取的绿色生活方式。
26. D 写作手法题。根据“Glaciers are formed in areas of high snowfall in winter and cool temperatures in summer。”可知，作者通过介绍冰川的形成来展开介绍。故选 D。
27. B 细节理解题。根据“They serve as natural reservoirs because about 75% of all the fresh water in the world is kept in glaciers. That’s why glaciers are quite important。”可知，冰川的重要性在于储存大量淡水。故选 B。
28. C 词义猜测题。根据“Large glaciers stop small earthquakes because the plates can’t move much under these huge objects。”可知，大型冰川阻止小地震，因为这些板块在这些巨大物体下无法移动太多，结合地质学常识可知，画线部分的含义是“地球表面的岩石板块”。故选 C。
29. B 篇章结构题。通读全文可知，第一段引入冰川；第二段介绍冰川的重要性；第三段总体介绍冰川消失的危害，第四段到第六段具体介绍冰川消失带来的后果；最后一段给出解决措施。故选 B。
30. B 观点态度题。根据“Many people are now living a green life which is a way of living with less carbon dioxide(CO₂) … These are helpful in slowing down global warming. With little effort and not much money, most of us can make a difference。”可推知，作者认为人们在努力拯救冰川。故选 B。

解析
【分析】
这是一篇说明文阅读题，我们可以分小题逐个梳理解题思路：
1. 第26题：判断作者开篇方式，需聚焦文章第一段内容，第一段介绍了冰川的形成条件、不同形状与大小，属于对冰川的基础介绍，据此匹配对应选项。
2. 第27题：询问冰川重要的原因，要定位原文中解释冰川重要性的语句，找到第二段中“储存全球75%淡水”的关键信息，对应选项即可。
3. 第28题：词义猜测题，需结合上下文语境，句子提及冰川阻止地震是因为plates在冰川下难以移动，结合地震相关的地质学常识，判断其含义为地球表面的岩石板块。
4. 第29题：篇章结构题，要梳理全文段落逻辑：第1段引入冰川话题；第2段介绍冰川的重要性；第3段总述冰川消失的危害；第4-6段分别阐述冰川消失带来的具体后果；第7段提出解决措施，对应选项中的结构。
5. 第30题：观点态度题，从原文最后一段找作者倾向，文中提到人们通过绿色生活减缓全球变暖来保护冰川，以此判断作者认同人们在努力拯救冰川的观点。
【解析】
1. 第26题：写作手法题。文章第一段“Glaciers (冰川) are formed in areas of high snowfall in winter and cool temperatures in summer. They can come in different shapes and sizes...”是对冰川的形成、形态大小进行介绍，属于通过介绍引入话题，故选D。
