A five-day Internet shutdown in Egypt failed to stop the protests that forced President Hosni Mubarak to resign. But it raised a technical question. Just how were Egyptian officials able to shut down Internet service in their country?
埃及为期5天的互联网关闭措施并未能阻止最终导致穆巴拉克总统辞职的示威活动。但它提出了一个技术性问题，埃及政府究竟是如何能够关闭国内的互联网服务的呢？
Craig Labovitz is chief scientist at Arbor¹ Networks, an Internet security company in the American state of Michigan. Mr. Labovitz says the Internet is not as indestructible as people might think. He says there are points where the flow of computer traffic can be restricted.
克雷格·拉博维茨（Craig Labovitz）是美国密西根州一家名为Arbor Networks的网络安全公司的首席科学家。拉博维茨先生称，互联网并没有人们想象的那么坚不可摧，互联网存在着一些可以限制计算机通讯的节点。
CRAIG LABOVITZ: "From a technical standpoint, the popular imagination of the Internet is as a network that can survive nuclear wars, can't be stopped, is everything, everywhere. But the engineering realities are a lot more prosaic². In many countries there are a few natural bottlenecks³, whether it be large data centers or right-of-ways."
拉博维茨：“从技术角度来说，互联网给人的普遍印象是它能在核战中幸存，不会被中断并无处不在。但技术方面的实际情况却平常得多。许多国家的互联网都存在一些天然关卡，它可能是大型数据中心或访问权限。”
Mr. Labovitz says his researchers tracked the Internet shut down in Egypt as it was being carried out. He explains that in Egypt, Internet users connect to the outside world through a small number of providers with international links.
拉博维茨先生，他的研究人员在埃及关闭互联网期间进行了跟踪。他解释说，在埃及，互联网用户只能通过少数几家拥有国际线路的宽带供应商与外界联系。
CRAIG LABOVITZ: "Although there are a hundred or more providers within the country -- domestic providers -- there really are only four providers that maintain external links to the external world. And there's an even a smaller number of data centers where the fiber⁴ optics cross Egypt. So you really just need to turn off a handful of machines to have this type of disruption."
拉博维茨：“虽然埃及国内有一百多家宽带供应商，但实际上只有4家具有国际线路，光纤遍布埃及的数据中心更少。因此，只需要关闭少数几台机器，就能造成互联网中断。”
News reports suggested that the fiber optic links for those networks are even all housed in the same building.
新闻报道指出，连接这些网络的光纤甚至都在同一栋建筑内。
Could a similar Internet shutdown take place in the United States? Craig Labovitz says that is less of a possibility because of a larger number of Internet providers and data centers.
美国是否也可能发生类似的互联网关闭事件呢？拉博维茨称，这种可能性相对较小，因为美国拥有大量的宽带供应商和数据中心。
Still, the recent shutdown in Egypt has raised new concerns about a proposal in the United States Congress. Critics say the legislation could make similar action possible in America.
不过，最近埃及关闭互联网事件引发了人们对美国国会一项提案的新的担忧。批评人士表示，这项立法将使美国采取类似措施成为可能。
The measure is known as the Protecting Cyberspace⁵ as a National Asset Act. Senator Joseph Lieberman of Connecticut first proposed the bill last June. Supporters say it would help protect the country's economic and national security from cyber attack. It would give the president the emergency power to shut down or seize parts of the nation's Internet in the event of a major threat.
这一措施被称为“像保护国有资产一样保护互联网空间法案”(Protecting Cyberspace as a National Asset Act，PCNAA)。康涅狄格州参议员约瑟夫·利伯曼（Joseph Lieberman）去年6月首次提出这一法案。支持者表示，这将有助于防止网络攻击威胁美国经济和国家安全。该法案赋予总统在美国面临重大威胁的情况下关闭或控制国内部分互联网。
Critics say the bill would give the president too much power. Some people call it the "Kill Switch Bill" -- an easy way to shut off the Internet. They say the government could use it to censor⁶ the Web and control the flow of information.
而批评人士表示，该法案将赋予总统过多权力。有些将其称为“生杀开关法案”--这是一个关闭互联网的简单途径。他们表示，政府可能利用该法案审查互联网并控制信息通讯。

as…as 结构的基本用法
其基本意思为“与……一样”，其中的第一个as副词，其后通常接形容词或副词(用原级)，第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点：
1. 在否定句中，第一个 as 也可换成 so：
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。
2. 在该结构的两个as之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much 不可数名词 as”和“as many 可数名词复数 as”：
You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。
I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。(R2/92)
其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(注意词序)：
She is as good a cook as her mother. 她和她妈妈一样是位好厨师。
也可说：She is a cook as good as her mother.
但不说：She is as a good cook as her mother. 或They are as good cooks as us.
3.But the engineering realities are a lot more prosaic.
a lot more，alot修饰比较级more。
4.So you really just need to turn off a handful of machines to have this type of disruption.
turn off(把…)关掉
例句：The tap won't turn off and there is water all over the floor.

a handful of少数、几个、不多
5.Critics say the bill would give the president too much power.
too much过分；太多
例句：It really is too much of you.
你太过分了。
much too为习语，其中的much修饰副词too；much too可视为too的加强说法，其语气比单独用too更强。如：
He spoke⁸ much too fast. 他说话说得太快了。
This is much too heavy for you to lift. 这东西太重，你拿不起来。
注意：much too与too much词序不同，用法也不同。从句法功能上看，much too的用法与too相同，但比too的语气更强；而too much在用法上则与much相同，但比much 语气更强。
