问题     When a housewife in a working-class district of Mexico City gets fed up with the lack of working lights in her local park, she logs on to Twitter and complains directly to the city’s mayor.
    In an age of incessant digital chat—and in a city of 22 million—this might seem futile. But the mayor, who has more than 600,000 Twitter followers, replies to her complaint within hours. He orders the city’s public works department to take action. Several weeks later, he posts photos of new lights being installed in the park and thanks the woman for bringing the problem to his attention.
    In fact, the mayor’ s Twitter feed reads like a chronicle of life in a metropolis. There are complaints and announcements about garbage collection, crime, traffic lights, construction delays etc. At first glance, it looks like a strange mix of unedited rants by aggravated citizens and upbeat public relations by an ambitious mayor. But a sustained look shows that a surprising number of these virtual conversations follow a cycle— citizen complains, mayor listens, city solves the problem—that until recently would have seemed impossible for an overpopulated and underfinanced metropolis in the developing world.
    In Latin America, Mexico City is not unique. Use of social media is growing at a breathtaking pace across the region. When Facebook passed the 1 billion user mark in October, few people noticed that 19 percent of those users live in Latin America(which only accounts for 8 percent of the world’s population). The governments of virtually all large Latin American cities now use social media to engage with citizens, and smaller cities are quickly following suit. The Inter-American Development Bank recently found that social media is used by governments in 70 percent of the region’s 140 "emerging cities"(those having 100,000 to 2 million residents and above-average economic growth rates).
    Although the press has focused on Latin American presidents who have embraced social media as a potent new channel for old-fashioned political communications, something very different is happening at the municipal level.
    Mayors seem to be betting that by micromanaging urban issues via Twitter or Facebook, they will give voters concrete evidence of their effectiveness in office. This is a risky tactic, of course. Many local governments that find it easy to virtually "engage" with constituents may not have the budgets, the organization, or the staff to actually solve the problems that generate complaints. The result, in that case, could be a voter backlash enlarged, ironically, over the same social media channels.
    I predict that social media will have a highly disruptive but largely positive effect in this context. These technologies will give new vitality to the ancient ideals of participation and accountability.
Which of the following cannot be inferred from paragraph 3?
选项 A、Social media is the only way through which people can send their complaints to the mayor.
B、The mayor have solved a lot of problems posted on the Twitter.
C、This phenomenon is usually very rare in a big developing city.
D、Twitter is very popular in this city.
答案A
解析 推断题。A项讲的是人们只能通过社交网络才能向市长发表抱怨．是无法推断出的，虽然第三段讲的是社交网络，但没有否定其他途径，所以A项不能推导出。B项可以从文中But a sustained look shows that a surprising number of thesevirtual conversations follow a cyclewcitizen complains，mayor listens，city solves theproblem推断出，市长解决了人们提出的各种问题。C项可以从文中that untilrecently would have seemed impossible for an overpopulated and underfinancedmetropolis in the developing world推导出。D项可以从文中In fact，the mayor’sTwitter feed reads like a chronicle of life in a metropolis推导出。因此，正确答案是A。
