At an office in Virginia，in the east of the United States，a team of ten net savvy workers

　　scours the web for sexual content，from basic sex education to sex acts.This“quality assurance‘’team is making sure that the blocking component of Symantec‘s Norton Internet Security 2000 computer program remains effective.This is because there is widespread parental concern about blocking websites with sexual content from children.

　　Website blocking is nothing new——services like Net Nanny and programs like Cyber Patrol and Guard Dog have been around for a few years now，protecting children and reassuring parents that only wholesome websites are accessed by the youngsters.Net Nanny and Cyber Patrol will prevent access to any questionable sites when the program is in place.

　　Now Symantec says it has created a new category in consumer software with a package that combines website blocking with a“firewall”，protecting your computer from hackers，snoopers and viruses，as well as preventing inadvertent disclosure of personal data.

　　In short，Norton Internet Security(NIS)，as the program is called，is designed to serve as the guardian of your digital health，keeping the bad things out and the private things in.

　　The Symantec program can be configured in many ways，the website blocking，for example，can be set to be either selectively permissive or total in its banning of websites，or switched off entirely.Also，Symantec‘s list of no-go areas，which on the CD now stand at around 36，000 addresses，is not confined to sex sites.The team in Virginia is also on the lookout for sites advocating drugs，or which contain references to violence or gambling，and keeps a watch on chat rooms，e—mail services，entertainment portals——even job search and financial pages.These sites can be blocked by the program.

　　Computer users can also refresh the address list online wim the Live Update feature which is used by Norton Anti—Virus(which is bundled with NIS)to load the latest virus definitions.This service is free for the first year but，including virus definition updates，it costs$1 9.95 a year thereafter.

　　The system is not perfect，however.Limited testing found the blocking of some “questionable” sites was not comprehensive.Trying to get access to a well—known US site such as Playboy results in an immediate blocking message with a standard invitation to report an “incorrectly categorized”site.By contrast.you could find in other countries such as New Zealand a sex site.

　　难句点津

　　Trying to get access to a well—known US site such as Playboy results in an immediate blocking message with a standard invitation to report an“incorrectly categorized”site.

　　[点津]句子的主语是一个动名词短语trying to get access to…，谓语是results in，宾语是

　　message，with引导的介词短语作定语修饰message，其中to report an…是invitation的定语。

　　美国东部弗吉尼亚州汉普顿的一个办公室里，10名精通网络的工作人员组成的小组正在搜索网络上从基础性教育到性行为等有关性的内容。这个“质量保证”小组正在确保赛门铁克公司“诺顿网络安全特警2000”的封锁还是有效的。这是因为众多父母希望屏蔽带有色情内容的网站以使孩子免受不良内容的影响。

　　网站屏蔽并不新鲜?像“网络保姆”这类服务和“网络巡警”、‘’看门狗‘’这些程序至今已运行了好几年。这些服务和程序保护孩子，也使家长放心，因为年轻人只能接触到健康的网站。当“网络保姆”和“网络巡警”运行时，可以阻止进入任何存在问题的网站。

　　现在，赛门铁克公司声称自己已经开发出了一种供用户使用的新程序，这种程序可以将网站屏蔽系统与防火墙结合起来，保护电脑免受黑客、偷窥者和病毒的袭击，同时也可防止无意中泄露个人信息。

　　总之，“诺顿网络安全特警”名如其实，它被设计成数字健康的卫士，保护你的隐私，将不好的东西排除在外。

　　赛门铁克的程序可以被设定为多种形式，以网站屏蔽为例，可以设置成部分屏蔽也可设置成全部屏蔽，或者完全将其关闭。另外，赛门铁克程序光盘上列出的禁入网站已多达3万6 千个，不只局限于色情网站。维吉尼亚的工作小组还在关注那些宣传毒品，或是包含暴力、赌博内容的网站。同时也监视聊天室、邮件服务、娱乐端口，甚至是工作搜索网站和财务方面的网页，这些网站都可以被该程序屏蔽。

　　计算机用户还可以用“诺顿防毒”程序(“诺顿网络安全特警‘’附带的)的”即时更新‘’功能在线刷新“禁入网站”名单，下载最新的病毒定义。这些服务在第一年是免费的，但之后包括对病毒定义的升级在内，每年要花费19.95美元。

　　但是这种系统并不尽善尽美。有限的几次测试就发现对“有问题的‘’网站的屏蔽并不全面。比如，想要进入美国的知名网站，如”花花公子“，结果就会马上出现一条屏蔽信息，报告这是个”错误分类“的网站。相反，你可以找到其他国家的色情网站，比如新西兰的。

　　1.D推断题。文章第一段提到，质量保证小组正努力确保赛门铁克公司的计算机程序有效工作，因为世界各地的父母都关心色情网站的屏蔽，以免让孩子接触到这类网站。由此推断，家长担心孩子受到色情网站的毒害，故选D.选项B的内容在文中的确提到，但这并非本段的重点，故不选。

　　2.A语义题。由题干关键词wholesome定位第二段。该段提到，网站屏蔽可以保护孩子，也使家长放心，因为年轻人只能接触到——网站。上文提到家长关心一些不良网站的屏蔽，这里能使冢长放心，说明年轻人浏览的应为内容健康的网站，结合选项A(健康的)、B(彻底的)、C(完全的)和D(完美的)可知，正确答案应为A.

　　3.D推断题。由题干关键词NIS定位文章第四段。该段首句的“总之”一词表明是对上段的总结。即第三段开始对这种新程序进行描述：它可以将网站屏蔽系统与防火墙结合起来，保护电脑免受黑客、偷窥者和病毒的袭击，同时也可防止无意中泄露个人信息。第四段则总结：“诺顿网络安全特警”被设计成数字健康的卫士，保护你的隐私……，结合选项可知应选D.其余三项A(为Symantec公司盈利)文中并未提到，B(允许其他人共享你的个人资料)与文意相悖。C(阻止你登录任何可疑的网站)说法过于绝对。

　　4.c推断题。由选项可知，本题内容涉及NIs program.文章第六段提到，计算机用户还可以用“诺顿防毒”程序的“即时更新”功能在线刷新“禁入网站”名单，下载最新的病毒定义，这些服务第一年是免费的，以后每年付19.95美元，排除A和D.文章之前还提到了该程序的功能：可以屏蔽内容不健康的网站，结合选项可知应选C.选项B以偏概全，文中提到包括对病毒定义的升级在内，每年要花费19.95美元，而不是说仅病毒定义就需要19.95美元。

　　5.D语义题。文章最后提到，系统并非尽善尽美，“花花公子”网站被屏蔽了，但却没能屏蔽新西兰的色情网站，由此推断，D正确。A(“花花公子”应该被包括在禁止网站的名单内)并非作者说这句话的重点，应排除;B(NIS在其他国家根本不奏效)、c(新西兰所有的网站都应该包括在禁止网站的名单内)两项过于武断，应排除。
