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.18选？A.skepticismB.relevanceC.indifferenceD.enthusiasm
选项 A.skepticism
B.relevance
C.indifference
D.enthusiasm
答案 A
解析 词义辨析【直击答案】本空格所在句是The plan has also been greeted with 18 by some computer security experts.解答本题，定语从句中worry一词是关键“一些网络安全专家仍有所担忧”。故本题答案为A项skepticism“怀疑”，表达含义为“一些网络安全专家仍旧对这一计划持怀疑态度。”【命题思路】该题考查的是词义辨析，需要结合下文来确定答案。【干扰排除】其他选项代入句中与上下文意思不符。with tolerance“忍耐地”，with indifference“漠不关心地”，with enthusiasm“热情地”。
