Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices． The action follows recent reports about the storing of information on the Apple iPhone． Some people consider location tracking to be a threat to personal privacy and security．
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks． This information is usually stored by the companies, not the devices, and there are laws to protect it． Law enforcement（執(zhí)法） agencies, for example, have to have a fairly high standard before it can access that data． And the phone company is also prohibited from selling that information．
Now, two researchers report that location tracking information is being stored directly on Apple devices． They said Apple’s newest operating systems gather global positioning system and timestamp information． The information is stored on the device in a file that is also uploaded （上傳） to any computer that the device is connected to． The researchers say the information is available to anyone who has access to the device or computer．
Allan Friedman says, “This raises additional concerns． There’s the idea that because it’s on my phone and on my computer, rogue applications（惡意程序） that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it．”
Apple says it is “not tracking the location of your iPhone”． It is simply keeping a database of Wi-Fi hotspots and cellphone towers near the user’s location． This information is meant to help the iPhone quickly find its location when needed．
Letters have been sent to some of the leading mobile device developers, including Apple and Google． The letters asked for more information about their location tracking systems． Allan Friedman calls this an important start to strengthening privacy laws． He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it． And perhaps the most important question is, is my location data with other facts about me?”
【小題1】Why did American lawmakers investigate the use of location-tracking systems on cell-phones?

A．wireless companies focus on personal privacy．

B．people are forbidden to get access to private data at will

C．phone companies may sell private information secretly

D．customers may ask wireless companies to locate their tracking

The following is a recent survey among teenagers:

Radio Most teenagers nowadays are not regular listeners to radio. They may occasionally tune in, but they do not try to listen to a program specifically. The main reason teenagers listen to the radio is for music, but now with online sites streaming music for free they do not bother, and users can choose the songs they want instead of listening to what the radio presenter/DJ chooses. Television Most teenagers watch television, but usually there are points in the year where they watch more than average. This is due to programs coming on in seasons, so they will watch a particular show at a certain time (as long as it lasts) but then they may watch no television for weeks. Teenagers are also watching less television because of services such as BBC iPlayer, which allows them to watch shows when they want. Whilst watching TV, adverts come on quite regularly (18 minutes of every hour) and teenagers do not want to watch these, so they switch to another channel, or do something else whilst the adverts run. Newspapers No teenager that I know of regularly reads a newspaper, as most do not have the time and cannot be bothered to read pages and pages of text while they could watch the news summarized on the Internet or on TV. Internet Every teenager has some access to the Internet, be it at school or home. Home use is mainly used for fun (such as social networking) whilst school (or library) use is for work. Most teenagers are heavily active on a combination of social networking sites. Facebook is the most common, with nearly everyone with an Internet connection registered and visiting >4 times a week. Facebook is popular as one can interact with friends on a wide scale. For searching the web, Google is the dominant figure, simply because it is well known and easy to use. Some teenagers make purchases on the Internet (on sites like eBay) but this is only used by a small percentage, as a credit card is required and most teenagers do not have credit cards. Many teenagers use YouTube to watch videos (usually anime which cannot be watched anywhere else) and some use it as a music player by having a video with the music they want to listen to playing in the background. Mobile Phones 99pc of teenagers have a mobile phone and most are quite capable phones. Usually, teenagers only use their phones for texting, calling. Features such as video messaging or video calling are not used—because they are expensive. Services such as instant messaging are used, but not by everyone. It usually depends whether the phone is Wi-Fi compatible, because otherwise it is very expensive to get Internet off the phone network. As most teenagers’ phones have Bluetooth support, and Bluetooth is free, they utilize this feature often. Mobile email is not used as teenagers have no need; they do not need to be connected to their inbox all the time as they don’t receive important emails.

Superman, Spider-Man, Batman and Iron Man ... .There is no shortage of superheroes. You find them in comic books, on the TV and the big screen.

In a survey of fans by the sci-fi and fantasy website, SFX.co.uk, Batman, 70 years old this year, was voted Britain's favorite superhero.

Unlike many crime-fighting superheroes Batman has no special powers. He can't fly like Superman or shoot a sticky web like Spider-Man.

Bruce Wayne is born to a wealthy Gotham City business family. However, when his parents are murdered his life changes completely.

Wayne feels anger at their deaths and guilty that he did not prevent them. He travels around the world learning how to fight. Upon returning to Gotham, he creates a disguise (偽裝) to enable him to fight crime without being recognized.

A childhood fear of bats leads him to choose to dress as one. His idea is that through the bat person he can prove to himself that he has overcome his childhood fears.

Wayne is the CEO of the company he inherits (繼承) from his father. He seems to live the lifestyle of a millionaire playboy. But this is a ruse (計(jì)策). He works hard at the image to allow himself the freedom he needs to do his work as a crime fighter. "Bruce Wayne, playboy" is the disguise Batman is the real person.

"Wayne is not a born superhero. Instead, he is a real, complex person," said Dace Golder, editor of the website. "He is the most realistic of all the superheroes. I am particularly interested in the emotional process by which a boy becomes a hero. His superhero qualities come from within."
