Mayor Boris Johnson Monday outlined plans to make London “the cleanest” by the 2012 Olympics and called for commitments from other world cities at a climate change conference. Leaders of the world's 40 largest cities are meeting in Seoul this week for a summit on combating global warming ---- the third to be held since 2005.

"What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine (内燃机)," said Johnson. He told a press conference the world's cities consume 75 percent of its energy and produce 80 percent of the emissions which cause climate change. "The problem of our planet is an urban problem," Johnson said.

He said the British capital wants to use the Olympics "to drive the greening and the improvement of our city" and noted that London is committed to reduce carbon emissions by 60 percent by 2025.

Johnson said the key measure was addressing the problems relating to domestic and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting (翻新) ---- installing lagging (绝缘层材料) ---- in large numbers of public buildings.

Johnson proclaimed himself a "passionate cyclist" and said he would push ahead with cycle super-highways around London.

London's air quality problem, he said, was caused by vehicle emissions from 8,300 antiquated (陈旧的) diesel (柴油) buses, which could be replaced by low-carbon vehicles. There were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles.

Johnson said there would be a substantial (实质上的) program in the next few years to produce a "cleaner, greener" bus for his city. "The age of the diesel-emitting bus has got to be over in London."

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（执法） 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 （上传） 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（恶意程序） 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?”

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．
