When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app (application program) from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on a map. You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data.

Android does not have an exact equivalent, but there are plenty of alternatives. A free app called Lookout offers the find-my-phone feature. The paid version allows you to wipe the data from your phone remotely.

Then there is your coffee shop’s WiFi network. Anyone with minimal technical expert skill can snoop on (窥视) people using shared wireless networks, harvesting passwords and other personal data. Lookout’s apps will caution you when you’ve logged on to an unsecure network, but cannot protect you once you’re there.

In order to protect yourself on such networks, you can use a virtual private network, or V.P.N. This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks. It also keeps websites from tracking you and, if you’re traveling, allows you to get access to sites that may be blocked in other countries.

If you have an iPhone, the simplest V.P.N. app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (浏览), as opposed to other V.P.N. apps that require you to start them up manually. This matters, because even if you decide you want a V.P.N. app, you want to spend approximately zero time thinking about it. For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly.

If even reading about the settings on your phone drives you crazy, then it is probably best to stay away from a V.P.N. app. But if you’re the type who can’t resist checking your bank balance from your corner bar, the hassle may be preferable to the risk.

64. Which of the following can warn you against the unsecure network?

A. Android.

B. V.P.N.

C. Lookout.

D. Find My iPhone.

答案：C

细节题。直接对应几个专有名词去文章里寻找即可。答案在文章第四段末尾，没有难度。注意后面就V.P.N.进行专门提问，所以此题B选项可能性就不大。

65. By using V.P.N., users can __________.

A. find their lost phone on the Internet

B. erase all the data from the phone remotely

C. check their bank balance now and then

D. save their browsing from being tracked

答案：D

细节题。C选项是文章最后提到的一个例子，并非文章重点强调的手机安全问题，所以排除。A选项是Find My iPhone的作用，B选项是Lookout的作用，所以排除。此篇文章为应用文，所以题目难度不高。不过话说回来，考学生这个题材的文章，命题者是也对GFW相当不满么？VPN都来了，翻墙也不远了吧。
