[解析]
(1)C.主旨大意题.由第一段中的Facebook has lost value nearly equal to Yahoo Facebook的市值损失几乎与雅虎相当,可以推断脸谱网上市后遭遇了巨大失败,故为答案C.
(2)C.细节理解题.由第三段To justify a stock price close to the lower end of the projected range in the IPO,say﹩28 a share,Facebook's future growth would have needed to match that of Google seven years earlier.That would have required increasing revenue by some80 percent annually and maintaining high profit margins all the while.要实现接近其公开募股说明书上的较低股价,比如每股28美元,这就要求脸谱网年收益增长要高达80%,并始终保持高利润率,故答案为C.
(3)A.理解推断题.本段后面the company clearly stated in a list of risk factors associated with its IPO:it hasn't yet figured out how to advertise effectively on mobile devices,The number of Facebook users accessing the site on their phones surged,脸谱网现在还未解决如何有效地在移动设备上做广告这一问题,而用手机登录其网站的用户数量却不断飙升,且文章通篇语义色彩都是消极的,故可推出此处应指脸谱网商业模式中的致命软肋,故答案为A.
(4)D.理解推断题.由倒数第二段Not only does that threaten to rub off on users,it's bad for recruitment and retention of talented hackers,who are the lifeblood of Zuckerberg's creation.脸谱网在市场上的失意不仅会影响到用户,还会影响招募和挽留天才黑客,而这些人正是扎克伯格创造力的命脉.由此推知,脸谱网的创新力会因其市场失意而受到损害,故答案为D.
