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.
【C11】
选项
A、carry on
B、linger on
C、set in
D、log in
答案
D
解析
本填空的动词词组出现在that引导的定语从句中+其先行词为systems,即systems使得用户做出本填空中的动作,而且本动作之后的副词just once说明这个动作只需要做出一次就能使用多种不同的服务;实际上本填空的答案在此前的原文信息中已经出现过(复现),即上文中的“single sign-on” systems,此处的single与本动词之后的just once是同义重复,因此本填空的动作意思应等同于sign-on。sign-on是“登录”的意思,则本填空答案是D项log in(登录)。A项carry on(继续)和B项linger on(徘徊)与其后的just once无法形成有意义的搭配。而C项set m(嵌入)无法表达登录的意思,本填空动作的主语users也无法做出嵌入的动作。
