Facebook managed to put its vast treasure trove(宝藏) of user data to good use before Friday’s tragic terror attacks in Paris. The social network customized its safety check feature let users know whether their friends and loved ones in Paris are safe.
Users in the area are being alerted(通知) by Facebook’s mobile apps, asked them whether they are safe, and offering to check on any of their friends. The app has also been sending out alerts to anyone who has friends in Paris, and Facebook’s website lets anyone check on the status and whereabouts(去向) of their friends as well as.
Most people have seen Facebook’s safety check for the first time today, and the company actually lanched it in respond to the Nepal earthquake earlier this year. At the time, Facebook CEO Mark Zuckerberg wrote: “When disasters happen, people need to know their loved ones are safe. It’s moments like this when being able to connect really matters.”
Facebook wasn’t the only tech company to direct reach out to its users in Paris after the terror attacks. AirBnB（空中食宿） sent its customers in Paris a email advising them staying in place and follow the directions from local authorities, and Uber（优步） used its app to advise users “not to move if absolutely necessary.”
【答案】
【1】before→after
【2】feature 后加 to
【3】asked→askiing
【4】as well as 去掉后面一个as
【5】and →but
【6】respond →response
【7】when→that
【8】direct →directly
【9】a→an
【10】if→unless
【解析】
试题分析：
【1】before→after 句意：上周五巴黎恐袭悲剧发生后，社交媒体“脸书”设法让其巨量的用户数据发挥了极大作用。根据句意故before→after。
【2】feature 后加 to 考察不定式，句意：脸书启用了定制版“安全签到”功能为了让用户借此知道在巴黎的亲友是否安全。不定式表目的。故feature 后加 to。
【3】asked→askiing 考察现在分词做伴随的状语，句意：脸书用户的移动端程序会弹出消息，询问他们是否安全，还可以帮他们确认他们的朋友是否也安全。故asked→askiing。
【4】as well as 去掉后面一个as考察固定结构，句意：脸书网站也向所有人开放查询他们的朋友的状况和去向。as well 也。故去掉后面一个as。
【5】and →but 考察连词，句意：大多数人可能都是今天才第一次发现脸书有安全签到功能。但其实早在今年尼泊尔地震时，脸书就推出了该功能。从句意可看出，前后句之间转折，故and →but。
【6】respond →response 考查固定结构in response to 响应，回答。
【7】when→that 考察强调句型 句意：这种时候，保持联系真的很重要，本句强调moments like this。
【8】direct →directly 考察副词，句意：不单单是脸书，还有其他科技公司也在恐袭发生后，第一时间想要与它们的巴黎用户取得联系。此句副词修饰动词短语reach out to.﹍。
【9】a→an 考察冠词 an e-mail 一封邮件，
【10】if→unless 考察连词，句意：除非绝对必要，否则不要乱跑。根据句意可知if→unless。
