We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices（装置）well after they go out of style. That's bad news for the environment – and our wallets – as these outdated devices consume much more energy than the news ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices – we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

    So what's the solution? The team's date only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand environment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

    Watching wooden dolls come to life may not be one of the most popular forms of entertainment today, but with over twenty years' experience, talented puppeteer (木偶表演者) Peter Roberts has earned himself the title "master puppeteer" because of his great ability to turn puppets into believable, almost living characters. "People are quite often surprised to hear what I do for a living and have little appreciation of puppy as a form of entertainment. But while the exact origins of puppet theatre are unknown, it has been popular in many cultures and may have been the very first kind of theatre," he explains.

    Roberts' shows are highly original. "A puppet show can involve anything from clowning(傻逗) to storytelling," he says.  Equally diverse are the audiences he performs for. "Some are attracted by the puppets themselves, while others enjoy the dialogue." Roberts believes that this form of entertainment can be appreciated by people of all ages and cultures.

    Roberts' interest in puppets started when he received some beautiful glove puppets one Christmas. He started putting on shows with these for family and friends and then moved on to handmade Chinese string puppets. Learning mostly from books and personal experience, he explains, "I was already spending most of my free time carving puppets and putting on shows, so I hardly noticed the change from students to full-time professional puppeteer."

    The puppets are designed specifically for each show, which is extremely time consuming. According to Roberts, "Sometimes what you expect and what you actually create in the end are two very different things. I've made some of my best puppets 'accidentally'."

    When most people hear the word "puppetry", they more than likely think of a way of keeping children entertained at birthday parties. Certainly the subject matter will be expected to be light-hearted rather than serious. However, Roberts wants to point out that puppets convey serious messages sometimes." he says.

    The Pope John XXIII Regional High School robotics team has brought about many crea-tions in its laboratories. Most of these creations have earned them prizes in their robotics leagues, articles in local media and praise from many people around the world. None of them, however, can equal to what they experienced during one of their most recent projects.

    The robotics team helped design and build an electrically during one of their most recent projects, girl during an event snonsored by the GoBabyGo program and Toyota. The goal of the disabled is to build an electncally opiated vehicle and meet the needs of a specific disabled child. After hearing about the program, the robotics team jumped on the opportunity.

    When they got to the hospital for the event，the team members joined forces with engi-neers from University of Delaware, Toyota employees and and doctors to help a girl named Jaleah.

    Using instructions provided on an iPad by GoBabyGo,they put together a plastic battery-oper-ated vehicle-one of 12 that were made at the event-that was bespoke to Jaleah. Her vehicle was a baby blue jeep that had designs from the hit Disney movie Frozen and was decorated with snowflakes (雪花)，butterflies and flowers.

    More importantly，the team rerouted the electrical system in the car so that Jaleah only needed to push a large button on the steering wheel to drive the car, giving her the freedom to move. In addition, they helped design special seating structure to keep Jaleah safely secured.

    When they completed the project, Jaleah and her parents' reactions took the PJ robotics members by surprise.“ It was really satisfying,” PJ junior Austin Fett said. “When she was riding it, she was having so much fun. It was a great feeling. ”

    While they are looking forward to their future projects and competitions in the FIRST Technology Challenge league, the robotics team will always remember the days they helped Jaleah become a mobile kid.

    “We made something that she will love and use forever,” PJ senior Keith Johnson said.

    When we are young we are taught that it's wrong to lie and we should always tell the truth. Unfortunately, most children lie even if they're told not to. Research carried out at the Institute of Child Study at Toronto University has shown that this might not be such a bad thing. Apparently (显然地), children who tell lies when they're two years old have a good chance of becoming successful adults (成年人).

    According to the research, at the age of two, 20 percent of children lie. At the age of three, 50 percent lie, and at four almost 90 percent lie. By the age of 12 almost every child tells lies.

    Lying needs much brain work. And the better the lie is, the more work the brain has to do. By training the brain early, researchers believe children will be able to think more clearly when they are adults.

    Recent research, carried out by the Science Museum in London, has shown some interesting facts about the way we lie as adults. According to the research, the average British man tells three lies every day, that's over 1,000 lies a year. However, the average woman apparently only lies twice a day.

    Most people think women are better liars (说谎者) than men although in fact they tell fewer lies. Popular women's lies include 'Nothing's wrong, I'm fine', 'I don't know where it is, I haven't touched it', and 'It wasn't that expensive'.

    Some people say you can lie as long as it's a white lie. A white lie is a lie told to avoid hurting someone's feelings. One of the most common lies for both men and women is 'It's just what I've always wanted', said after opening a present from their partner.

    Last year my children gifted me a stainless steel (不锈钢的) coffee plunger (法式按压咖啡壶). I love to start the day with a strong black coffee and couldn't wait to use it. I looked forward to the following morning's coffee making, knowing that I probably wouldn't smash (打碎) this plunger as easily as I had done so often in the past.

    But as I poured my first cup of coffee, the plunger spilled (洒出) all over the table. Thankfully no one was around to see my disappointed face! I kept trying, but each morning would see me wiping up the coffee. Then I realized that if I poured very slowly there would be no spilling.

    This was at first a very painful experience. My normal practice was to rush through breakfast so that I could get on with my day.

    But in time I learned not only to pour slowly but to enjoy the experience: the smell, the taste, and the stillness of a new day.

    It prompted (促使) me to reflect upon whether there were other areas of my life I was rushing through. Most of life, it seemed.

    I started to leave extra time to do even the most ordinary tasks. When shop owners would apologize for keeping me waiting, I'd say, "Not a problem, I'm not in a hurry." Even hanging out washing became pleasurable when a couple of extra minutes of standing still and listening to the birds singing in the trees around me became part of my routine.

    Besides, one of my favorite experiences living in the inner city for many years was sitting on the front doorstep of our home spending time with strangers. We sat on the steps, each of us with a cup of coffee in our hands, listening to each other's stories. It was one of the warmest things about living in a busy city. It was as if the world around us slowed to a pace (步伐) we could both handle.

    Stillness and quietness not only slow the pace of life, but also feed the soul, helping us to enjoy the world's small pleasures.
