If you think texting(发短信) while walking is dangerous, just wait until everyone starts wearing Google's smart, Internet-connected glasses. These glasses can do anything you now need a smartphone or tablet computer(平板电脑) to do —and then some.
    In Google's video, a guy wearing the "Project Glass" is shown getting subway information, making an appointment with a friend for coffee and showing the directions in a bookstore, all with the help of the glass. It ends with him playing an instrument for a woman and showing her the sunset through a video chat.
    The "Project Glass" Google displayed have a sleek(光滑的) wrap-around look and appear nothing like 3-D glasses. In development for a few years, the project is the idea of Google X, the online search-leader's secret department that produced the self-driving car and could one day send elevators into space.
    Google posted the video and short blog post about “Project Glass” on April 4^th, asking people to offer feedback(反馈) through its Google Plus social network. By April 5^th, about 500 people did, voicing a mix of amazement and concern about the new technology. What if people used it in cars and could not concentrate on driving? What about the effect on(对……有影响) your sight of having a screen so close to your eye?
    Some asked for the glass, but Google isn't giving those out just yet. The company didn't say when normal people can expect to get their hands on a piece of Project Glass, but going by how quickly Google will come out with new products, it may not be long. Enderle said that it could be about six months to a year before wide tests are coming, and a year or more for the first version(版本) of the product.

    What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping, but none of them are worried about the road ahead.

Well, all of this could be the future of driving. There are several companies, including Google, working on driverless (无人驾驶的) cars, which are currently in the testing stages. If the tests are successful, these electric, self-driven cars could be available very soon. But, how is it possible for a car to drive itself?

    Cars already have many features allowing them to take over for drivers in certain situations. Some features include cars being able to park themselves, or slow down when they detect objects (物体) close by. They can also control the speed if there are dangerous conditions, such as snow or slippery (滑的) roads.

    Other features have also changed the way drivers react to some situations. Scientists and engineers believe, with the help of wireless signals, cameras and GPS, we are now at a stage where creatinga safe self-driving car might be possible.

    The self-driven car may be the answer to lowering the number of deadly (致命的) accidents caused by careless drivers or dangerous conditions. However, there are still some people who do not like the idea. American lawyer Whit Drake, for example, doesn't believe these cars are safe. He thinks the possibility of the technology making a mistake will be too high.

    Our life has become easier and more colorful because of mobile phones and the Internet. However, a number of worrying problems have come along with them.

Many car accidents are caused by mobile phones. Some drivers use mobile phones to get on the Internet while driving. Looking at their mobile phones and not at the road, these drivers have become a danger to us all.

Many of the dangers of the Internet are well known. Children who visit websites without their parents‘' permission sometimes talk to elder people they don't know and put themselves in great danger. People with blogs sometimes post information of people they don't know on their websites without permission. Some people even use the Internet to get personal information that we do not want them to have.

    Mobile phone and the Internet safety tips：

Use a ‘hands-free' phone if you need to use a mobile phone when you drive.

     In difficult driving situations such as in rain or snow, do not use your phone at all.

     Do not make very important phone calls while driving. They take your attention (注意力) off the road.

     Tell your children not to talk with anyone they do not know on the Internet.

     In an embarrassing situation (尴尬场合), be careful with people around you.

Don't give out any personal information on the Internet.

New App Helps People Remember Faces

    Large gatherings such as weddings and meetings can be socially Q flooded with people. Learning people's names only adds to the stress. A new facial-recognition app could come to the rescue, but experts suggest people should be careful while using it.

    The app, called SocialRecall, connects names with faces through smartphone cameras and facial recognition, avoiding the need for formal introductions. "It breaks down these social barriers we all have when meeting somebody, "says Barry Sandrew, who created the app and tested it at an event attended by about 1, 000 people.

    After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in through social media. At the event, the app is active within a previously set geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the person, displays the person's name, and links to his or her social media information. To protect Privacy, it recognizes only those who have agreed to use. And the app's creators say it automatically removes users' data after an event.

    Ann Cavoukian, a expert who runs the Privacy by Design Center of Excellence praises the app's creators for these protective measures. She added, however, that when people choose to share their personal information with the app, they should know that "there may be unexpected results down the road with that information being used in another situation that might come back to bite you."

    The start-up project has developed the app for people who suffer from prosopagnosia, or "face blindness, "a condition that prevents people from recognizing people they have met. To use this app, a person first receives an image of someone's face, from either the smartphone's camera or a photograph, and then tags it with a name. When the camera spots or recognizes that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.
