问题     Friday 11 March 2011 started like any other day on Twitter. A celebrity story was trending that morning, along with business news about Google, when suddenly, at 12:46 a. m. , thousands of tweets started coming out of Tokyo. Something big had happened in the area, and Twitter was first to report it: a massive earthquake had hit Japan, followed by a huge tsunami. Eyewitness testimo-nies from cities rocked by the quake flooded the web, and then as the tsunami swept the coastline, people scrambled up bridges and buildings and posted footage on YouTube and Facebook. The camera work was shaky, but the content was compelling—their world was falling apart, yet they continued to film.

    Over the last few years, big news stories, such as the Japanese earthquake in 2011 and Hurricane Sandy in 2012 have been reported mainly by ordinary individuals. It was citizen journalists armed with smartphones who brought these stories to the world. Mobile technology has enabled people at the scene of the event to post videos, photos and commentaries more quickly than paid journalists. The landscape of reporting and of deciding what is newsworthy has changed: news organizations and their reporters no longer set the agenda.
    The content of the news has changed too, as stories told by citizen journalists are often more personal and have more emotional appeal. Unlike investigative journalism, these blog posts and tweets seldom include background information or give a broad overview. People haven’t got time to collect and scrutinize facts or explore the bigger picture.
    But in other ways, citizen journalism supports investigative journalism. It is now easier for ordinary people to expose corruption and cover-ups in government and private companies. In Africa, a virtual noticeboard called Mimiboard helps people to report rigged elections and human rights abuses. These noticeboards create pressure for change and reform, and sometimes they work—corrupt government officials have changed their working conditions. But because of the risks involved, Mimiboard relies on anonymous posts, and anonymous publishing comes with its own set of challenges: it makes it very difficult to verify information.
    The freedom to publish whatever we want is exciting and empowering, but there are serious ethical implications. Unlike traditional journalism, citizen journalism is largely unregulated, with little or no accountability—there is no one to check the facts or trace sources. People can spread rumours or anonymously post a defamatory article and get away with it. Because posts are rarely checked and verified, citizen journalism is more vulnerable to scams and can help to spread false information.
    Citizen journalism is still finding its way. Yet, despite the challenges, this new way of reporting news has had a largely positive and democratizing effect. Armed with our smartphones, we are now telling our own stories, controlling our own destinies and creating impact and change around the world. "The choice we face," says Clay Shirky, professor in new media at New York University, " isn’t whether or not this is the media environment we want to operate in. This is the environment we’ve got. The question we all face now is ’ How can we make the best use of this media?’ "
Questions 56 to 60
Mark each statement as either true(T)or false(F)according to the passage.
People in Africa can get access to Mimiboard by computer to fight against environment pollution and government corruption.

选项 A、TRUE
B、FALSE

答案B

解析 原文谈到Mimiboard的地方在倒数第三段,根据此段第三句中的“Mimiboard helpspeople to report rigged elections and human rights abuses”可知,Mimiboard是一个可以让人匿名举报操控选举和侵犯人权的平台,并不包括环境污染。本题表述与文章意思不符,因此错误。
