You may charge (充电) your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria (细菌) and viruses (病毒) than any surface in a public restroom. So it won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them.

The research on bacteria and viruses led to the invention of PhoneSoap. It is not actually liquid (液体). It is a phone charger that uses the electromagnetic radiation (辐射) to kill 99. 9 percent of bacteria and viruses, cleaning your phone while it charges.

The founders are cousins Wes LaPorte and Dan Barnes, "Certain types of bacteria and viruses are really on our phones," says Barnes. "It would be the fastest, most powerful way to kill them."

PhoneSoap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the PhoneSoap charger box. The process only takes a few minutes but, Barnes says, "The idea is that you can leave it in there overnight if you want to keep charging and it cleans the phone fully."

The founders found the right companies and then started shipping (推向市场) the product in late November. By last week's International Consumer Electronics Show in Las Vegas, PhoneSoap was very popular with people. The founders have left their present jobs and are selling PhoneSoap without a stop. "We sell out Phonesoap every day, and we will try to provide enough PhoneSoap," Barnes says. "It's been a great challenge."

On a sunny day last January, people got together at a parking lot in Las Vegas to see small vehicles that look more like colourful eggs than ordinary cars. These vehicles are electric, run on two wheels instead of four and hold only passengers. Thanks to their tiny size, six of the vehicles would fit in a parking spot. If the idea of parking such a small car makes you nervous, don' worry: these cars can park themselves. And they can return to their owners when controlled by a button on a cellphone.

The vehicle is called the EN-V (Electric Networked-Vehicle). It is built by General Motors, or GM, and it points to what future vehicles might be like. It is designed to be energy-saving, solve environment problems and help ease traffic jams, parking and safety concerns. The automaker says its next concept car (概念车) will help  drivers get whatever they want. According to GM, the company has also designed an electric vehicle named Lean Machine. However, it is a small three-wheeler and this single-seater vehicle looks like a motorcycle. One day, such small, electric vehicles might safely carry people around, especially in crowded cities.

    Scientists and engineers are finding new ways to make cars safer, smarter and more efficient, or use less energy. New cars may help you keep track of your health by reminding you to take medicine. If it's electric, your car may send you a message reminding you to recharge it. Cars will talk to other cars, your computer, your phone and your iPad. They'll help drivers save energy, watch out for other drivers and avoid walkers on the streets.

This is the future of vehicles: safer, smarter and more energy-saving. Beside they might even drive themselves down the highway through a city. You can sit back and enjoy the ride.

(an extract from a detective story)

"Sit down," Henderson said, sitting down in an armchair himself and looking at Logan. "What are you here for?"

"I understand you had a party last night," said Logan, a police officer.

"Yes," said Henderson. "Oh! I hope the neighbours haven't been complaining about the noise again. "

"Not that I know of," said Logan. "But a young girl, Fran, who came to the party hasn't been home yet."

"Fran!" said Henderson. "Yes, she was here. She left early, as I remember—about one o'clock. I happened to notice what the time was when she came to say goodbye. But nobody else left until about four in the morning."

Henderson looked quite relaxed.

"Did you know Clare?" asked Logan suddenly.

"Oh, God!" Henderson sat forward. "You don't think…the same thing has happened to Fran?"

"We're keeping an open mind," said Logan, watching him carefully, "but we're giving it our full attention."

"Well, yes. I can understand that," replied Henderson, getting comfortable in the armchair again.

"So," repeated Logan, "did you know Clare?"

"Well, sure. I knew who she was. But we never had anything to do with each other," said Henderson, giving Logan a big smile.

"Who else was at your party?" asked Logan.

"People from the university," said Henderson. "Students, teachers."

"David?" asked Grant, Logan's partner.

"Yes, David was here for a time," Henderson smiled again. "But he's not really a party animal. He probably left early."

"What do you mean, probably?" asked Grant. Henderson looked at Grant. Grant was sixty with thick black hair and large moustache. His clothes, as always, looked rather old: a blue jacket and grey trousers. He did not look much of a party animal either.

"Well, I don't check when my guests arrive and leave," said Henderson. "And some people just leave when they want to go home. They don't come and say goodbye. Anyway, sometimes I can be difficult to find." Again he looked at Logan, raised his eyebrows and gave her a big smile. "I sometimes end up in the bedroom."
