　　2011年考研英语已经结束，英语二是改革以来的第二次考试，难度较之去年稍有提高。就各部分来说，第一部分完形填空难度较之去年有所降低，涉及的是一篇社会类的文章。阅读理解A部分对考生的词汇量要求有所提高，专业性也较强，相比于2010年来说，今年阅读理解的文章和题目在难度方面有所增加。B部分新题型是以多项对应的形式出现。第三部分翻译难度与去年持平，涉及的是环境方面的话题。最后一部分小作文是常见的书信形式，要求写一封祝贺加建议信;大作文也是考纲规定的图表作文，作文部分难度都不是很大。

　　第一部分：完形填空

　　文章是取自New York Times(《纽约时报》)2010年7月3日，原文标题为Taking the Mystery Out of Web Anonymity(揭开网络匿名的面纱)。文章探讨的是网络匿名这一现象给美国社会带来的一系列严重后果，政府决定采取一些措施来解决这个问题。词汇、固定搭配这是传统的两大考点，此外也侧重于对文章意思的理解。考生要学会分析句内和句际的逻辑关系以及篇章内容。

　　Taking the Mystery Out of Web Anonymity

　　THE Obama Administration is trying to fix the Internet’s dog problem。

　　The problem, as depicted in Peter Steiner’s legendary 1993 New Yorker cartoon, is that on the Internet nobody knows you’re a dog. And thus the enduring conundrum over who can be trusted in cyberspace。

　　The Internet affords anonymity to its users — a boon to privacy and freedom of speech. But that very anonymity is also behind the explosion of cybercrime that has swept across the Web。

　　Can privacy be preserved while bringing a semblance of safety and security to a world that seems increasingly lawless?

　　Last month, Howard Schmidt, the nation’s cyberczar, offered the Obama administration’s proposal to make the Web a safer place — a “voluntary trusted identity” system that would be the high-tech equivalent of a physical key, a fingerprint and a photo ID card, all rolled into one. The system might use a smart identity card, or a digital credential linked to a specific computer, and would authenticate users at a range of online services。

　　The idea is to create a federation of private online identity systems. Users could select 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 a government-issued Internet driver’s license. (Civil liberties groups oppose a government system, fearful that it could lead to national identity cards。)

　　Google and Microsoft are among companies that already have these “single sign-on” systems that make it possible for users to log in just once but use many different services。

　　In effect, the approach would create a “walled garden” in cyberspace, with (virtually) safe neighborhoods and bright (cyber) streetlights to establish a sense of a trusted community。

　　Mr. Schmidt described it as a “voluntary ecosystem” in which “individuals and organizations can complete online transactions with confidence, trusting the identities of each other and the identities of the infrastructure that the transaction runs on。”

　　Still, the administration’s plan has divided privacy rights activists. Some applaud the approach; others are apprehensive. “It seems clear,” Lauren Weinstein, the editor of Privacy Journal, wrote “that such a scheme is a pre-emptive push toward what would eventually be a mandated Internet ‘driver’s license’ mentality。”

　　The plan has also been greeted with skepticism by some computer security experts, who worry that the “voluntary ecosystem” envisioned by Mr. Schmidt would still leave much of the Internet vulnerable. They argue that all Internet users should be forced to register and identify themselves, in the same way that drivers must be licensed to drive on public roads。

　　“The privacy standards the administration wants to adopt will make the system both unwieldy and less effective and not good for security,” said Stewart Baker, a former chief counsel of the National Security Agency who favors government-issued Internet driver’s licenses。

　　But Marc Rotenberg, executive director of the Electronic Privacy Information Center, a privacy rights group, said such criticism was unfair. He said the Obama administration had created a policy framework that will make it possible for private industry to improve privacy and security technologies。

　　Some members of the Internet’s technical community say that the Web-of-trust approach is too little, too late to solve the Internet’s security problems. The problem is no longer just about cyberspace stalkers, thieves and con artists, but about the trustworthiness of the very fabric of the network itself。

　　“We’re now seeing attacks on the Internet’s plumbing,” said Rodney Joffe, senior technologist at Neustar, an Internet infrastructure firm. “If you get control of the plumbing there are lots of things you can do because the plumbing was never designed for a world where there is a lack of trust。”

　　The essential plumbing components are the routers, which direct traffic on computer networks. Operators of these routers — mostly private companies — share instructions with each other on how to direct that traffic. They trust the information is accurate. But at least three times this year, a substantial fraction of the global network’s messages were mis-routed through China, potentially opening millions of users to spying or tampering. Chinese Internet engineers say the misroutings were mistakes; other engineers are not so sure。

　　“If our web of trust is corrupted or penetrated or broken, I don’t quite know what to do about that,” said Vinton Cerf, a Google vice president and one of the designers of the Internet. “That’s one of the nightmares that I worry about。”

　　He is pushing efforts to create standards that would secure the Internet’s plumbing, though those may take longer than a decade to be put in place globally. As for making the network more secure for users, he said he was optimistic and that he saw a relatively straightforward — though not exactly inexpensive — way to make the network more secure。

　　In the future, he envisions a card that each of us will carry, perhaps equipped with a fingerprint reader, that will in effect be a one-time password system. It will digitally hold all of our different personalities: who we are at work, while playing on-line games, banking and using our smart phones and make it possible for others to be sure we are who we say we are。

　　But Mr. Joffe said he worried that the time for such systems might already have run out。

　　“Imagine what would happen if people lost trust in using the Internet: what would that do to our economy?” Mr. Joffe asked. “You would have to go down to your local bank branch and you’d join 5,000 other people waiting to do their banking. That infrastructure has gone away and the banks can’t cope with it anymore。”
