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.
5. Why did grassland fires destroy more houses than forest fires?
A. There were fewer and fewer forest fires.

6. What may cause increased homes in wildfire boundaries according to the text?
A. Reduced urban areas.

D. Increased love for nature.
7. What do homeowners in grasslands need to do according to Anderson?
A. Warn themselves of forest fires.
B. Move their houses to forested areas.
C. Learn more about the fire risk.
D. Reduce the destruction of grasslands.
8. Which of the following can be the best title for the text?
A. The Terrible Fires
B. Wildfires in the WUI Areas
C. Protecting Homes from Wildfires
D. Grass Fires：A Greater Threat to Homes

答案：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。
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。

斯莫基熊是美国林务局的标志性吉祥物，它有着著名的口号“只有你能防止森林火灾”，它因警示森林火灾而闻名，但事实上，对大多数美国房主来说，草地火灾的威胁更大。
森林火灾以其猛烈程度而闻名。然而，一项发表在《科学》杂志上的新研究分析了20世纪90年代以来野火边界内房屋的位置后发现，在21世纪初，森林火灾仅造成了33%被野火摧毁的房屋。与我们的想法不同，64%的此类房屋是被草原火灾摧毁的。研究人员发现，这是因为尽管森林火灾对建筑物的破坏性更大，而且森林火灾的数量有所增加，但更多被野火烧毁的建筑物建在草原上。
根据这项研究，如今野火边界内的房屋数量是30年前的两倍。有两个因素导致了这种情况。这种影响的53%可以用越来越多的烧毁区域来解释：野火比过去更常见、更猛烈。另外47%是由于房屋越来越多地扩展到专家所说的“荒野 - 城市交界带（WUI）”，即房屋与自然区域相邻的地方。
加州大学圣巴巴拉分校的环境政治学教授莎拉·安德森说，林区的房主通常很清楚自己面临的火灾风险。但住在草地地区的人可能没有注意到这种危险。“这篇论文可能意味着我们需要做更多的公共教育，”安德森说。
加州大学合作推广部的森林顾问兼县主任亚娜·瓦拉乔维奇说，有一些方法可以提高生存率。例如，房主可以通过堵塞通风口来保护自己，这样火就不会落到屋檐上，把植物和木质覆盖物从地面移开，并用金属栅栏代替木质栅栏。
5. 为什么草原火灾摧毁的房屋比森林火灾多？
A. 森林火灾越来越少。
B. 更多被烧毁的房屋在草原上。
C. 森林火灾对房屋的破坏性更小。
D. 草原上的房屋质量更低。
6. 根据文章，什么可能导致野火边界内的房屋增加？
A. 城市区域减少。
B. 进入荒野 - 城市交界带的房屋减少。
C. 野火更加猛烈。
D. 对自然的热爱增加。
7. 根据安德森的说法，草原上的房主需要做什么？
A. 提醒自己注意森林火灾。
B. 把他们的房子搬到林区。
C. 更多地了解火灾风险。
D. 减少对草原的破坏。
8. 以下哪一个可以作为这篇文章的最佳标题？
A. 可怕的火灾
B. 荒野 - 城市交界带的野火
C. 保护房屋免受野火侵害
D. 草地火灾：对房屋的更大威胁
