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.
【C9】
选项 A、recall
B、suggest
C、select
D、realize
答案C
解析 本题考查动词辨析。该动词的主语是Users，宾语是which system to join，此处的which system(哪种系统)说明了最佳选项应该是C项select(选择)，即用户选择加人哪种系统。其他选项虽然单纯从语法上看都可以，但A项recall(回忆)的意思根本讲不通。B项suggest (建议)一般应该是建议别人如何，但本动词的主语是Users，即用户自己，并不合适做出suggest的动作。D项realize(实现)与宾语which system to join很难构成有意义的动宾搭配。
