问题     When Hurricane Katrina ravaged the U. S. Gulf Coast in 2005, Facebook was the new kid on the block. There was no Twitter for news updates, and the iPhone was not yet on the scene. By the time Hurricane Sandy slammed the eastern seaboard in 2012, social media had become an integral part of disaster response, filling the void in areas where cell phone service was lost while millions of Americans looked to resources including Twitter and Facebook to keep informed, locate loved ones, notify authorities and express support.
    Researchers have now started publishing data on the use of social media in disasters, and lawmakers and security experts have begun to assess how emergency management can best adapt. The new playbook will not do away with the emergency broadcast system and other government efforts. Rather, it will incorporate new data from researchers, federal agencies and nonprofits that have begun to reveal the exact penetration of social media in disasters.
    The Federal Emergency Management Agency(FEMA)wrote in its 2013 National Preparedness report that during and immediately following Hurricane Sandy, "users sent more than 20 million Sandy-related Twitter posts, or ’tweets,’ despite the loss of cell phone service during the peak of the storm. " Following the Boston Marathon bombings, one quarter of Americans reportedly looked to Facebook, Twitter and other social networking sites for information. When the Boston Police Department posted its final "CAPTURED!!!" tweet of the manhunt, more than 140,000 people retweeted it.
    Each disaster sparks its own complex web of fast-paced information exchange. That’s a good thing, says Mark Keim, associate director for science in the Office of Environmental Health Emergencies at the U. S. Centers for Disease Control and Prevention(CDC), it can both improve disaster response and allow affected populations to take control of their situation as well as feel empowered.
    Drawing up an effective social media strategy and tweaking it to fit an emergency, however, is a crucial part of preparedness planning, says disaster sociologist Jeannette Sutton, a senior research scientist at the University of Colorado at Colorado Springs who studies social media in crises and disaster. For the Boston Marathon incident, she found no consistent hash tag on Twitter, which can make tracking relevant information difficult. Even searching for the word "Boston" may fall short, she says, because it could lead to unrelated matter like Boston tourism or fail to capture relevant tweets that did not include the word Boston. As part of disaster preparedness, she says, it would be useful to teach the public how to use social media effectively, how to get information from the Web and also how to put out useful information.
    All the fast-paced information available via social media does pose inherent risks when navigating emergency situations. One is the rapid spread of misinformation—as was the case after the Boston bombings with the identification of a missing man as a possible suspect. Although mistakes often get fixed via the "Wikipedia effect," in which other users correct the errors, Sutton notes that false information can easily go viral. Another key risk is scammers using social media to steal cash. The FBI has warned that social media can also be a lucrative platform for scam artists that crop up in the wake of tragedy. After the Newtown, Conn. , school shooting, for example, the FBI arrested a woman who allegedly claimed to be the relative of a dead victim and solicited money via Facebook and other sources.
According to Paragraph 2, the relationship between the new playbook and traditional disaster response can be best described as______.
选项 A、incorporation
B、exclusion
C、replacement
D、competition
答案A
解析 本题考查考生对第二段中有关社交网络方式在救灾中的应用与传统的方式之间的关系的理解。第二段的第二句明确指出“新的救灾方法不会完全抛弃紧急广播系统和其他政府的努力。相反，它会纳入从研究人员、联邦机构和非营利组织获得的数据，已开始显现社交媒体在灾难中的渗透。”其中，新的救灾方法指的就是社交媒体资源的应用，而紧急广播系统和其他政府的努力代表的就是传统救灾方式，由“will not do away with”“incorporate”这些词语可以看出，这二者的关系就是“兼容、合并、共存”，即[A]选项。[B]、[C]、[D]均是命题人故意设置的干扰选项，与A选项是直接对立的关系，均不正确。
