①Snow can be fun, but what does snow do? Is it good for plants? Is it good for animals? Is it good for you and me?
②Snow covers(覆盖) plants that must stay in the ground all winter. Snow is like a blanket(毯子). Because the plants are covered, wind, ice, and cold cannot hurt them. Plants that are covered with snow can live through the cold winter. Animals like mice stay under the ground all winter too. Snow helps to keep them warm. Snow is good for plants and animals.
③Snow protects people too. In the past, people in the far north sometimes built houses of snow. They built a house from hard blocks(砖) of snow. They put blocks up one by one to make a round snow house. Sometimes people today still build houses like this.
④Snow is good in other ways. Melted(融化) snow gives us water for our wells and our rivers. When winter is over, the sun warms the snow. The snow melts slowly, and water goes into the soil. Plants grow well in this soil.
⑤Sometimes snow is not good. Heavy snow makes life hard for animals and people. When snow is thicker, it may be hard for animals to look for food. Also, thick snow may bring trouble to people's life. For example, people may fall down and get hurt. What's worse, when the snow of winter melts fast in spring, sometimes there is more water than rivers can carry, so the rivers may overflow(漫出). The whole town is in danger.

解析
【解析】
27. 定位文章第①段，作者连续提出了4个和雪的作用相关的问题，以此开启整篇文章，对应选项C“通过提问”，其余选项讲故事、列数字、举例子均不符合开篇特征。
28. 定位文章第②段，文中说明雪像毯子覆盖植物，能阻挡风、冰和寒冷伤害植物，帮助植物越冬，对应选项B“保护植物不受风和寒冷的侵害”，其余选项的“让植物长得更快”“给植物提供食物”“改变植物颜色”均无原文依据。
29. 定位文章第⑤段，明确提到冬季的雪在春季快速融化时，水量超过河流承载能力，河流就会漫出，对应选项C“河流可能泛滥漫出”，其余选项内容和雪快速融化的后果无关。
30. 梳理文章结构：第①段总起引出雪的作用的话题；第②③④段分别介绍雪对动植物的益处、雪对人的保护作用、雪在供水等其他方面的好处，共同阐述雪的益处；第⑤段转而介绍雪的负面影响，整体为“总-分（分述益处+分述弊端）”的结构，对应选项A的结构图示。
