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.
【C2】
选项 A、for
B、within
C、while
D、though
答案C
解析 本题考查上下文逻辑关系。填空之前的原文信息是can privacy be preserved，强调保护隐私。而填空之后的原文信息是bringing safety and security to a world(将安全和保障带给世界)。首先，从逻辑上看，填空前后的信息是明显对立的，并且在时间上是同步的，能够表达这个意思和逻辑关系的是C项while(与……同时)；其次，从语法上看，填空之后直接出现了bringing safety and security to a world，while doing是一个常见的搭配结构，因此最佳选项是C项while。其他选项例如A项for (因为，为了)表达因果逻辑关系，B项within(在……之内)强调范围，D项though(尽管)表达让步逻辑关系，均无法在语法上和逻辑上同时符合题意，予以排除。
