Smokey Bear，the iconic U.S. Forest Service mascot with the famous slogan "Only You Can Prevent（防止）Forest Fires"，is famous for warning against forest fires，but for most US homeowners，in fact，grass fires are more of a threat（威胁）.
Forest fires are well known for their violence（猛烈）. However，after analyzing the locations of homes within wildfire boundaries（边界）since the 1990s，a new study published in Science found they were responsible for just 33 percent of houses destroyed by wildfires in the early 2000s. Different from what we thought，64 percent of such houses were destroyed by grassland fires. This is because even though forest fires are more destructive to buildings and the number of forest fires has increased，much more buildings burned by wildfires were built in grasslands，the researchers found.
There are twice as many homes within wildfire boundaries today as there were 30 years ago，according to the study. Two factors have caused the situation. Fifty-three percent of this effect could be explained by more and more burned areas：wildfires are more common and violent than they used to be. The other forty-seven percent was caused by the increased expansion（扩展）of homes into what experts call the wildland urban（城市的）interface（WUI），where houses are against natural areas.
Homeowners in forested areas are often quite well aware of their fire risk，says Sarah Anderson，a professor of environmental politics at the University of California Santa Barbara. But people living in a grassy space may not notice the danger. "This paper probably implies we need to do a lot more public education，" Anderson says.
There are ways to increase the survival rate（生存率），says Yana Valachovic，forest adviser and county director at the University of California Cooperative Extension. For example，homeowners can protect themselves by blocking vent openings so that fire can't land in eaves（屋檐），pulling plants and wood coverings away from ground and using metal fences to replace wood ones.

B
【语篇解读】本文是一篇说明文, 围绕着草地火灾对住宅的威胁及其原因展开, 提供了统计数据和专家建议, 从野火的损害、房屋的分布位置以及房屋的火灾防护措施等方面进行了介绍和分析。
5. B 解析: 推理判断题。根据“This is because even though forest fires are more destructive to buildings and the number of forest fires has increased, much more buildings burned by wildfires were built in grasslands, the researchers found.”可知, 虽然森林火灾更具破坏性, 但是更多的房屋建在草地上, 因此更容易被草地火灾摧毁。故选 B。
6. C 解析: 细节理解题。根据“wildfires are more common and violent than they used to be”可知野火更频繁和激烈。故选 C。
7. C 解析: 细节理解题。根据“But people living in a grassy space may not notice the danger. ‘This paper probably implies we need to do a lot more public education,’ Anderson says.”可知, Anderson 认为居住在草地上的人们对于火灾的风险意识不足, 意味着他们需要提高火灾风险意识。故选 C。
8. D 解析: 标题归纳题。文章核心内容是草地火灾比森林火灾摧毁更多房屋, 还分析了原因及应对建议, 重点突出草地火灾对房屋有更大威胁。故选 D。
