This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

    The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

    Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

    The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels.

    Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”

    Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around £120, which will go on sale in March.

    Put your car keys away and forget about your travel pass — it's time to do a bit of walking.

    National Walking Month is organized every May by Living Streets, an organization that campaigns for the rights and the needs of pedestrians — indeed, the organization was previously known as the Pedestrians' Association. The association's aim is to make streets safe, attractive and enjoyable spaces for people to live, work, shop and play. By putting people (rather than vehicles) first, Living Streets wants to create streets and spaces where people feel happier, healthier and more sociable.

    The annual campaign gives participants a great opportunity to experience the many virtues（优点）of walking. These include the physical health benefits of becoming fitter; the environmental advantages of not using vehicles（车辆）; the joy of local discoveries seeing more of your local area on foot; the enjoyment of walking with other people, whether family, friends or work colleagues and finally the stress relief that comes from walking—walking can clear your head.

    Walk to School Week, 19 to 24 May, is part of the month's activities and its aim is to encourage parents to send children to school on foot, rather than take them in the car or let them use public transport. The movement was started in 1995 with only five participating schools and now two decades later, more than one million children take part.

    Similarly, there is Walk to Work Week, 12 to 16 May, where grown-ups are encouraged to walk. In the morning, getting off the bus a stop early or parking a few streets away is a good way to add more steps to the daily total. And during the working day, rather than having lunch at the desks or in the canteen, take a walk and get some fresh air. Walk home with your workmates and chat away about everything under the sun but work!

    The behaviour of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放）by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

    The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，whichinstead focus on architectural and technological developments.

     ‘Technology is going to assist but it is not going to do everything,'explains Katy Janda, a UKERC senior researcher，‘consumption patterns of building users can defeat the most careful design. 'In other words，old habits die hard, even in the best-designed eco-home.

    Another part of the problem is information. Households and bill-payers don't have the knowledge they need to change their energy-use habits. Without specific information，it's hard to estimate the costs and benefits of making different choices. Feedback (反馈） facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

    Social science research has added a further dimension (方面），suggesting that individuals'behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒温器) , for example. Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

    Six years ago at the age of 35,I suddenly decided I wanted to learn the cello（大提琴）.Straight away I rented an instrument and appeared before Wendell Margrave,professor of musical instruction.

    "You can be as good as you want to be,"Margrave said rather mysteriously.On a piece of paper he drew the notes E and F.He showed me where to put my fingers on the neck of the cello and how to draw the bow.Then he entered my name in his book: 10 am,Tuesday.Tuesday followed Tuesday,and soon it was spring.

     Thus began my voyage out of ignorance and into the dream.E-F,E-F,we played together—and moved on to G.It was a happy time.I was again becoming something new,and no longer trapped as the same person.Surely the most terrible recognition of middle life is that we are past changing.We do what we can already do.The cello was something I couldn't do.Yet each Tuesday this became less and less true.Riding home on the bus one snowy night and learning the score of Mozart's C-Major Quintet(莫扎特的C大调五重奏),I felt the page burst into music in my hands.I could by then more or less read a score,and was humming（哼唱）the cello line,when suddenly all five parts came together harmonically（和谐地） in my head.The fellow sitting opposite stared.I met his glance with tears,actually hearing the music in my head for the first time.Could he hear it too, perhaps?No,he got off at the next stop.

    As the years slipped by,my daughter grew up,playing the piano well.My goal was that she and I would one day perform together.I also wanted to perform in public with and for my peers,and to be secretly envied.I continued to play,to perform,but it is not the same. Before, when I heard a cello,it was all beauty and light.Now,as the TV camera gets close to Rostropovich's face,I recognize that his smile shows his incredible determination.Even for him,the cello is a difficult instrument that doesn't respect your ambitions.I picked up my cello and practiced.As good as I wanted to be,I am as good as I'm going to get.It is good enough.

    In an industry with low margins (利润) where the traditional wisdom is led by Walmart, the key to success is lowering operating costs. A big part of those costs are in labor, so it is no surprise that the retail industry has been a leader in using more part-time workers to keep labor costs down, holding the line on wages, not training, and with few exceptions, seeing employees as a cost to be minimized. There is no doubt that these businesses fight for every dollar of margin. Unlike trend-leading hi-tech companies which spend a lot of money on employees to get them innovated, retail industry can spend very limited money on their employees.

    What researchers found was that companies were often staffing their stores far too low, and that many stores tended to perform better with higher staffing levels and were more profitable. Let's let that sink in for a minute. The stores were making more money (with all other things being equal) when they spent more on employees.

    They also found that retailers didn't do a very good job when staffing levels are just the actual demand in those stores. In fact, they set staffing levels identically across stores, even when the needs of the stores varied considerably. The average store did not appear to be understaffed, but there were enough that were understaffed and effect on overall company profitability was substantial.

    Interestingly, the same researchers persuaded the retail chain to run an experiment with them and slightly raise staffing levels to the amount that their analysis of historical data suggests would be ideal. Yes, labor costs obviously jumped when they did that, but so did profits. In retail, labor is a small percentage of costs—the biggest part is the cost of the products they sell. So, the net effect was an increase in profits of $7.4 million across 168 stores on an annual basis.

    What can we learn from this? One question worth thinking of is: How can traditional retail industry survive the increasingly severe market? Especially now with the growth of online retail, the one thing stores still have going for them is one to one customer contact with salespeople. If retailers cut that down to almost nothing, then they have effectively eliminated their competitive advantage against online stores.

    I was given the book Running on Faith written by Jason Lester as a birthday gift last month. After I started reading, I really couldn't keep my eyes off it. It is always inspiring to read a story of someone who has gone through obstacles to reach his goals.

    Jason Lester is a disabled (残疾的) extreme athlete. When he was twelve years old, a fast car ran a red light and hit him. Then he was sent into the hospital with twenty broken bones and. a famous baseball player, but at that a seriously injured arm. Jason had always wanted to become a time that dream was gone.

    However, Jason loved sports and he still wanted to be a good athlete. He began running and taking part in duathlons(铁人两项) in high school. Years later in 2004, he decided to start training for the Ironman, and has competed in many extreme races since then. In 2008, Jason became the first disabled athlete to complete the Ultraman (320 miles of biking, swimming and running) ,and it led him to an ESPY award (奖项) for Best Male Athlete with a Disability in 2009.

    If you are in a bad situation and don't know what to do now, Running on Faith is a good book for you. If you love running and want to reach some race goals, this book is good for you, too. Anyway, this book is worth reading for everyone who loves reading and wants to turn dreams into reality.
