问题     Worried about Internet companies spying on your online browsing? You might turn to something called a virtual private network to protect your privacy. But researchers say these networks can themselves be insecure.
    Earlier this year, the federal government rolled back rules that would have prevented Internet service providers from tracking your activity online. Comcast, AT&T and other providers are now allowed to track and sell your personal data too—with much less fear of regulatory action.
    One solution is a VPN, which is like a dark, secret tunnel you use to go from your computer to a website. While you’re inside the tunnel—clicking on Instagram photos or checking your bank account—third parties can’t see what you’re doing. There are lots of reasons people around the world use VPNs: to hide location, to access work networks, even to avoid government censorship (审查).
    Internet providers handle customer privacy in different ways. Some say you have to opt in for them to sell your data. Because of Internet-connected devices, providers can see more than the websites you browse.
    So, who cares whether Time Warner Cable or Verizon knows when I turn off my lights or whether I stock my fridge with Swiss or cheddar?
    For one thing, those data points can be used to target advertising. And the government or private companies could use the information to deny services, like health insurance—or even water.
    Some VPNs promise anonymous (匿名的) browsing for free or just a few dollars a month; they claim not to share your data. But these services don’t always deliver on their promises. Sometimes the medicine might be worse than the illness. In the first major review of VPN providers, what researchers found was alarming. Nearly 40 percent injected malware (恶意软件).
    Experts suggest researching a VPN before using it and to think of it as a supplementary tool, not a privacy solution. They advise reading the VPN service provider’s privacy policy to see whether it collects or retains any user information that could be traced back to you. [br] According to the author, what is the main purpose of using a VPN?
选项 A、To defend the Internet users’ privacy.
B、To cover up the users’ residence.
C、To visit the websites the users like.
D、To relieve the government’s burden.
答案 A
解析 事实细节题。定位段首句提到，一个解决方案是虚拟专用网络，它是可以联通计算机和网站的秘密隧道，紧接着第二句做进一步说明，进入隧道时第三方看不到你在做什么。即使用虚拟专用网络的目的是为了保护用户的隐私，故答案为A)。B)“隐匿用户住址”，该段第三句提到世界各地的人使用虚拟专用网络其中的一个原因是隐藏位置，这里是指上网地址，并非住址，故排除；C)“访问用户喜欢的网站”与该段第三句中的“访问工作网络”不吻合，故排除；D)“减轻政府负担”，文中未提及相关内容，可以排除。
