语 篇 提 能.阅读理解Snow falls in the earths extreme North and South throughout the year. However, the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道), but only on the highest mountains.Snow contains much less water than rain, but much of the water the world uses comes from snow. Melting snow provides water for rivers, electric power stations and agricultural crops. In the western United States, mountain snow provides up to seventyfive percent of all surface water supplies.Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. Snow also influences the movement of sound waves. The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snows surface will help to send back sound waves.Snow may be beautiful, but it can be deadly. It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. Others die from heart attacks caused by too much physical activity out in the cold.People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. These include food, emergency medical supplies, and extra clothing to stay warm and dry.语篇解读本文为一篇说明文。文章介绍了全球降雪的分布特点、作用及可能造成的危害。1Mountain snowfall _.A. is heavier than that in the South and the North PolesB. has never occurred near the Equator of the earthC. brings less of the water the world uses than rain doesD. provides up to seventyfive percent of water supplies worldwide答案与解析A推理判断题。根据文章首段前两句内容可知，地球的两极终年都有降雪。但是降雪量最大的地方是在山脉地区的冬季。因此可知，A项表述正确。2Snow protects plants and wild animals from cold weather by _.A. supplying much more airB. limiting heat movementC. absorbing strong windsD. sending back sound waves答案与解析B细节理解题。根据第三段前三句可知，降雪可以保护动植物免于严寒。这是因为雪里面含有大量的空气，这能够阻止热量的散失。故答案选B项。3Snow can be deadly mainly because it can _.A. cause road accidentsB. make people stuck in winter stormsC. lead to heart attacksD. make people victims of snowstorms答案与解析D细节理解题。根据文章倒数第二段内容可知，雪很美丽，但也可以致命。由于降雪，很多人会死于车祸和心脏病。因此四个选项中只有D项能全面概括所有内容。故答案选D项。4What will the text probably tell us following the last paragraph?A.
