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【C1】________across the Web.
    Can privacy be preserved【C2】________bringing safety and security to a world that seems increasingly【C3】________?
    Last month, Howard Schmidt, the nation’s cyber-czar, offered the federal government a【C4】________to make the Web a safer place—a "voluntary trusted identify" system that would be the high-tech【C5】________ of a physical key, a fingerprint and a photo ID card, all rolled【C6】________one. The system might use a smart identity card, or a digital credential【C7】________to a specific computer, and would authenticate users at a range of online services.
    The idea is to【C8】________a federation of private online identify systems. Users could【C9】________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【C10】________by the government.
    Google and Microsoft are among companies that already have these "single sign-on" systems that make it possible for users to【C11】________just once but use many different services.
    【C12】________, the approach would create a "walled garden" in cyberspace with safe "neighborhoods" and bright "streetlights" to establish a sense of a【C13】________community.
    Mr. Schmidt described it as a "voluntary ecosystem" in which "individuals and organizations can complete online transactions with【C14】________, trusting the identities of each other and the identities of infrastructure【C15】________which the transaction runs."
    Still, the administration’s plan has【C16】________privacy rights activists. Some applaud the approach; others are concerned. It seems clear that such a scheme is an initiative push toward what would【C17】________be a compulsory Internet "driver’s license" mentality.
    The plan has also been greeted with【C18】________by some computer security experts, who worry that the "voluntary ecosystem" envisioned by Mr. Schmidt would still leave much of the Internet【C19】________. They argue that all Internet users should be【C20】________to register and identify themselves, in the same way that drivers must be licensed to drive on public roads.
【C4】
选项 A、reason
B、reminder
C、compromise
D、proposal
答案D
解析 本填空考查名词辨析。本名词处于一个offer sb. sth. 的结构中，且之后有不定式to make the Web a safer place作后置定语修饰本名词。再通过研究破折号之后的同位语信息发现，这个同位语就是本名词的同位语，对本名词详细展开说明。根据这些信息很容易判断出答案为D项proposal(建议)，即Howard Schmidt(主语)向联邦政府提出一个建议，这也是最合理的意思。其他选项例如A项reason(理由)、B项reminder(提示)、C项compromise(妥协)不但意思不符合题意，这三个名词都无法与破折号之后的同位语信息匹配。
