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) the plants that must stay in the ground all winter. Snow is like a blanket(毯子) because when the plants are covered, wind, ice, and cold cannot hurt them. Plants that are covered with snow can live through the cold winter. Some small animals stay under the ground all winter too. Snow helps to keep them warm. Snow is good for plants and animals.
③ Snow 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(融化的) 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 thick, it may be hard for animals to look for food. Also, thick snow may bring trouble to people's lives. 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 may be in danger.
