(10 points) 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. 1． A.swept B.skipped C.walked D.ridden 2． A.for B.within C.while D.though 3． A.careless https://www.docsj.com/doc/d52692805.html,wless C.pointless D.helpless 4． A.reason B.reminder https://www.docsj.com/doc/d52692805.html,promise D.proposal 5． https://www.docsj.com/doc/d52692805.html,rmation B.interference C.entertainment D.equivalent 6． A.by B.into C.from D.over 7． A.linked B.directed C.chained https://www.docsj.com/doc/d52692805.html,pared 8． A.dismiss B.discover C.create D.improve 9． A.recall B.suggest C.select D.realize 10． A.relcased B.issued C.distributed D.delivered 11． A.carry on B.linger on C.set in D.log in 12． A.In vain B.In effect C.In return D.In contrast

考研英语二真题解析曲巍巍

2010(2) (1)“Su s tainability” has become a popular word these days, but to Ted Ning, the concept will always have personal meaning. (2)Having endured a painful period of unsustainability in his own life made it clear to him that sustainability-oriented values must be expressed through everyday action and choice. (3)Ning recalls spending a confusing year in the late 1990s selling insurance. (4)He’d been th rough the dot-com boom and burst and, desperate for a job, signed on with a Boulder agency. (5)It didn’t go well. (6)“It was a really b ad move because that’s not my passion,” says Ning, whose dilemma about the job translated, predictably, into a lack of sales. (7)“I was miserable. (8)I had so much anxiety that I would wake up in the middle of the night and stare at the ceiling. (9)I had no money and needed the job. (10)Everyone said, ‘Just wait, you’ll turn the corner, give it some time.’” 【篇章导读】本文节选自杂志《体验生活》（Experience Life）2009年12月刊上的一文，描述了Ning如何辗转挣扎、前途未卜的处境。sustainability（“承受力”）一词对于考生而言比较陌生，准确理解其意义的关键在于结合文中出现的关键词汇，如endured a painful period、through the dot-com boom and burst、turn the corner、give it some time等进行推断。本短文共三段。第一段指出Ning对于“承受力”的个人体会及其缘由，第二段讲述Ning痛苦经历的背景，第三段直接引用Ning的话，具体讲述Ning所经历的那段无法承受的痛苦生活。 【试题解析】 1. “Sus tainability” has become a popular word these days, but to Ted Ning, the concept will always have personal meaning. 【结构分析】 1）这是一个由两个并列句构成的简单句。 2）第一个并列句“sus tainability” has become a popular word these days是主系表结构；第二个并列句是but to Ted Ning, the concept will always have personal meaning。 【词汇解析】 1）sustainability n. ①承受力；②可持续性 e.g. a) They expressed their concerns about environmental sustainability. 他们表达了对环境可持续发展的关注。 b) We should take care of the spiritual sustainability of laid-off workers. 我们应该关注下岗职工的心理承受力。 〖拓展〗sustain v. ①承受住，支撑；②持续 sustainable adj. ①可支撑的；②可持续的 unsustainable adj. 无法承受的
