Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives

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 cell phone 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.Because the systems can store users’ information
B.Because many users have suffered loss after using them.
C.Because it is thought to threaten users’ privacy.
D.Because many reporters have shown the problem of the systems.
【小題2】Allan Friedman believes that ________.
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
【小題3】What do we know from Paragraph 3?
A.Location tracking information is stored online.
B.Apple’s newest operating systems collect all kinds of information.
C.Location tracking information may be uploaded to any iPhone.
D.Apple’s newest operating systems may reveal the private information of users.
【小題4】Which of the following statements is TRUE according to the passage?
A.Apple denies that it tracks the location of users.
B.The researchers may misunderstand the Apple’s systems.
C.The global positioning system is to blame for rogue applications.
D.The iPhone can quickly find its location by using its user’s information.
