问题 The Internet affords anonymity to its users,a blessing to privacy and freedom of speech.But that very anonymity is also behind the explosion of cyber-crime that has 1 across the Web.Can privacy be preserved 2 bringing safety and security to a world that seems increasingly 3?Last month,Howard Schmidt,the nation’s cyber-czar,offered the federal government a 4 to make the Web a safer place-a“voluntary trusted identity”system that would be the high-tech 5 of a physical key,a fingerprint and a photo ID card,all rolled 6 one.The system might use a smart identity card,or a digital credential 7 to a specific computer.and would authenticate users at a range of online services.The idea is to 8 a federation of private online identity systems.User could 9 which system to join,and only registered users whose identities have been authenticated could navigate those systems.The approach contrasts with one that would require an Internet driver’s license 10 by the government.Google and Microsoft are among companies that already have these“single sign-on”systems that make it possible for users to 11 just once but use many different services.12.the approach would create a“walled garden”n cyberspace,with safe“neighborhoods”and bright“streetlights”to establish a sense of a 13 community.Mr.Schmidt described it as a“voluntary ecosystem”in which“individuals and organizations can complete online transactions with 14,trusting the identities of each other and the identities of the infrastructure 15 which the transaction runs”.Still,the administration’s plan has 16 privacy rights activists.Some applaud the approach;others are concerned.It seems clear that such a scheme is an initiative push toward what would 17 be a compulsory Internet“drive’s license”mentality.The plan has also been greeted with 18 by some computer security experts,who worry that the“voluntary ecosystem”envisioned by Mr.Schmidt would still leave much of the Internet 19.They argue that all Internet users should be 20 to register and identify themselves,in the same way that drivers must be licensed to drive on public roads.20选？A.invitedB.appointedC.allowedD.forced
选项 A.invited
B.appointed
C.allowed
D.forced
答案 D
解析 词义辨析【直击答案】本空格所在句是They argue that all Internet users should be__20__to register and identify themselves,in the same way that drivers must be licensed to drive on public roads.本句含义为“他们认为所有的互联网用户都应注册并证明自己身份，就像司机在公路上驾驶必须有驾照一样。”解答本题，后一句中的must是重点，司机必须有驾照，同理，网络用户也必须注册和证明自己身份。所以本题答案为D项forced“强迫”。be forced to…等同于must。【命题思路】该题考查的是词义辨析。【干扰排除】从语法角度讲，每个选项带进空格都正确，但是语义上就讲不通了。首先根据意思排除A、B项。网络用户注册并确认身份本来就是文中赞成的观点，进而排除C项。
