2、track v. 追踪、跟踪；n. 轨道、踪迹
3、browse v. 浏览、随意翻阅
4、typically adv. 通常、典型地
5、cookie n. 饼干；（网络）cookie，网站留在用户电脑里的小型文本文件

【解析】
① 本句是倒装句（表语前置）。正常语序应为How online companies track internet users … is at issue。此处介词短语 At issue（表示“正在讨论/争议的”）作表语被前置到句首，is是系动词，后面的how从句作主语（主语从句）。
② 主语从句how online companies track internet users as they browse from site to site online, typically through cookies 中，how是连接副词（在从句中作方式状语）；online companies是主语，online是形容词，companies是核心名词；track是谓语；internet users是宾语，as they browse from site to site online是as引导的时间状语从句，as是连词，they是主语，browse是谓语，from site to sites是介词短语做状语，online是副词做状语；typically through cookies是介词短语做方式状语，as状语从句的意思是：当他们在线从一个网站浏览到另一个网站时，通常是通过追踪cookie实现的。主语从句的意思是：网络公司如何追踪互联网用户在线从一个网站浏览到另一个网站，通常是通过cookie来实现的；
③ 括号内的information that a website leaves in your computer so that the website will recognize you when you use it again 是对cookies的注释说明。核心名词是information；that a website leaves in your computer是that引导的定语从句修饰 information，that是关系代词作宾语，指代information；a website是主语；leaves是谓语；in your computers是介词短语做状语；定语从句的意思是：网站留在你电脑里的一段信息；so that the website will recognize you when you use it again是so that引导的目的状语从句，so that是连词，the website是主语，will recognize是谓语，you做宾语，when you use it again是when引导的时间状语从句，when是连词，you是主语，use是谓语，it做宾语，again是副词状语；目的状语从句的意思是：以便下次你再访问该网站时，网站能够识别出你；

目前争论的焦点在于，当用户在网上从一个站点浏览到另一个站点时，网络公司是如何追踪这些用户的，通常靠的便是cookie（即网站留在你电脑里的一段信息，以便下次你再访问该网站时，网站能够识别出你）。

【解析】
① 本句是主系表结构，主干为The most harmful version … is the web alternative of …。主语是The most harmful version, "third-party" cookies，The是限定词，most harmful是形容词最高级作定语，version是核心名词，"third-party" cookies 是同位语，解释说明version，is是系动词；表语是the web alternative of a company posting security guards across the internet to monitor what you do，核心是the web alternative，the是限定词，web是名词作定语，alternative是核心名词，of a company posting … 是介词短语作后置定语修饰alternative，动名词复合结构内部a company是逻辑主语，posting是动名词，security guards是宾语，across the internet是介词短语做状语，to monitor what you do是to do不定式做目的状语，to monitor是不定式，what you do是what引导的宾语从句做monitor的宾语，what是连接代词作do的宾语，you是主语，do是谓语，表语从句的意思是：这就相当于网络版的，一家公司在互联网各处派驻保安人员，监视你的一举一动；

Google declared in a blog post Wednesday that it would no longer use or support third-party cookies, nor would it create or use any other technology that tracks individual users across the web.
【生词】

2、blog post n. 博客文章、博文
3、third-party adj. 第三方的
4、track v. 追踪、跟踪
5、individual adj. 个别的、单个的；n. 个人
【解析】
① 主句主干是Google declared … Wednesday。Google是主语；declared是谓语；in a blog post是介词短语作状语，Wednesday 是名词作时间状语，意思是：谷歌周三在一篇博文中宣布；
② that it would no longer use or support third-party cookies, nor would it create or use any other technology that …是that 引导的宾语从句，作declared的宾语，该宾语从句由否定连词nor连接两个并列的否定成分。
③ 第一部分：it would no longer use or support third-party cookies。it是主语；would no longer是情态动词would +副词短语no longer；use or support是并列谓语；third-party cookies是宾语，third-party复合形容词作定语，cookies是核心名词。句子意思是：它将不再使用或支持第三方cookie；
④ 第二部分：nor would it create or use any other technology that tracks individual users across the web。nor是否定连词其后须用部分倒装，情态动词would提前到主语it之前；it是主语；would是情态动词；create or use是并列谓语；any other technology是宾语，that tracks individual users across the web是that引导的定语从句修饰technology，that是关系代词作主语，tracks是谓语，individual users是宾语，across the web是介词短语做状语，定语从句的意思是：追踪用户跨网站浏览行为的技术；句子意思是：也不会创建或使用任何其他追踪用户跨网站浏览行为的技术；
⚠️ 考点：nor + 倒装。nor 表示：“也不”，紧跟其后的分句要用部分倒装：助动词/情态动词提到主语前，本句即 would it create …。

As Lee Tien of the Electronic Frontier Foundation noted, third-party cookies were already on the retreat, with Apple and other makers of popular web browsers moving to block them.
【生词】
1、note v. 指出、特别提到；注意；n. 笔记、记录
2、retreat n./v. 撤退、退却（on the retreat 在退却/衰退之中）
3、on the retreat（短语）正在减少、正在退潮
4、browser n. 浏览器
5、block v. 阻止、屏蔽、封锁
6、Electronic Frontier Foundation（专有名词）电子前沿基金会（EFF，一家数字权利组织）
【解析】
① As Lee Tien of the Electronic Frontier Foundation noted是as引导的方式状语从句，As是连词；主语是Lee Tien of the Electronic Frontier Foundation，Lee Tien是核心人名，of the Electronic Frontier Foundation是介词短语作后置定语，修饰Lee Tien，表示：电子前沿基金会的Lee Tien；noted是谓语。句子意思是：正如电子前沿基金会的Lee Tien所指出的那样；
② 主句是third-party cookies were already on the retreat。third-party cookies是主语，were 是系动词，already是副词；on the retreat是表语，整体意为：第三方cookie本就已经在走向退潮；
③ with Apple and other makers of popular web browsers moving to block them是with复合结构（with + 宾语 + 现在分词）作伴随状语；with是介词, Apple and other makers of popular web browsers是宾语，同时也充当现在分词moving 的逻辑主语，of popular web browsers是介词短语作后置定语修饰other makers，moving to block them是现在分词短语作宾语补足语，moving是现在分词，to block them不定式作目的状语，其中them指代third-party cookies，意思是：苹果及其他主流网络浏览器制造商纷纷开始屏蔽它们；
⚠️ 考点：with 复合结构/独立主格—“with + 名词/代词 + 现在分词”，逻辑主语与现在分词构成主谓关系，整体作伴随状语。

Privacy advocates say pitches can be targeted effectively by basing them on where the user is at the moment, not where he or she has browsed previously online.
【生词】
1、advocate n. 拥护者、倡导者；v. 提倡、主张
2、pitch n. （推销的）说辞、广告推销；v. 投掷、抛
3、target v. 将…对准、以…为目标（be targeted 被定向投放/精准定位）
4、effectively adv. 有效地
5、previously adv. 先前、之前
6、browse v. 浏览
【解析】
① 主句主干是Privacy advocates say …。Privacy advocates是主语，Privacy是名词作定语，say是谓语，pitches can be targeted effectively by basing them on where … 是省略了引导词that宾语从句，作say的宾语。pitches是主语；can be targeted是谓语；effectively是副词作状语；by basing them on …是介词短语作方式状语，在by短语中，basing them on … 是动名词短语作by的宾语：basing是动名词，them是宾语，指代pitches，on where …是介词短语，on为介词，这对应固定搭配base A on B（把 A 建立在 B 之上），句子意思是：隐私倡导者表示，定向推送广告仍然可以有效实现；
② on后面接两个并列的where引导的宾语从句：第一个 where the user is at the moment，where是连接副词，the user 是主语，is是系动词，at the moment表语，句子意思是：用户当前所在的位置；第二个用not表否定的并列项，where he or she has browsed previously online——not是否定副词，where是连接副词，he or she是主语，has browsed做谓语，previously与online均为副词状语，句子意思是：不是基于他/她先前在网上浏览过的位置；
