Watching a 3D movie can more than double the concentration powers and the cognitive（认知的）process of children,new re-search claims.

    A study by visual technology firm Read and led by child psychologist Dr Richard Woolfson and associate lecturer at Goldsmiths Patrick Fagan suggests that children aged between 7 and 14 experienced twice the cognitive processing speed and performed better in tests after watching 20 minutes of a 3D film.

    This suggests that children's attention spans have shortened in the last decade due to unlimited access to entertainment,including on-demand TV,gaming and social media.

    A 2015 study claimed that watching 3D content had a similar effect to brain-training exercises.

    Consumer psychologist Mr Fagan said that the increased stimulation found in watching something in 3D "exercised" the brain and improved performance in the short term.

    3D films can play the role of brain-training "games and help to make children 'smarter' in the short term," he said. "The response speed after watching 3D was almost three times as quick as that gained from watching 2D; in other words,3D helps children process aspects of their environment more quickly.This is likely because 3D is a mentally exciting experience which 'gets the brain's juices flowing'."

    If you want to become a fluent English speaker you should take some advice: There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills you should first master the skills of reading and listening.

    Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence, the meaning of the unfamiliar words, etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you come across ， but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passages or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it.

    As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening.

    For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes.

    If you follow these pieces of advice, your speaking and writing will improve automatically, and you can be sure that with a little effort they will become perfect.

    Do you like shopping? Or does the thought of wandering round the shops fill you with terror? For some of us, shopping is an enjoyable way of spending our spare time and our money. For me, it's something I would rather avoid. Thank goodness for the Internet! It's more convenient to buy CDs, electrical items, and even food from the comfort of your sofa. But that's not the only reason: price is an important factor. We can buy goods and services cheaper online. But sometimes the problem is knowing what to buy. This has led to a type of shopping called “showrooming”.

    Showrooming is something I've done. I will go to a shop to see, touch and try out products but then go home and buy them online at a knock-down price. I'm not alone in doing this. Research by a company called Foolproof found 24% of the people showroomed at Christmas in 2013.

    Amy Cashman, Head of Technology at TNS UK, says the reasons for this new shopping habit are that people are lacking time, lacking money and they want security about the products they are buying. She explains that consumers are not only shopping online at home but they are using the Internet in store or on their smart phones to shop around.

    But does this mean technology will kill shops? Certainly shops will change. They will have to offer more competitive prices or encourage people to buy more by giving in-store discounts or free gifts.

    We mustn't forget that buying in a shop means you can get expert advice from the sales assistant and you can get good aftercare. It's good to speak to a real human rather than look at a faceless computer screen, but at least by showrooming, you get the best of both worlds.

    Are you afraid of moving up to senior high school? It is a completely new experience, but you shouldn't worry. We've got a guide to help you.

    You're not alone. Remember that everybody else in your year is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help. If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to, because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes. There are lots of differences between junior high school and senior high school. You will have your lessons with different teachers in different rooms. You will have homework for different subjects on different days, so make sure you get organised. Make sure you know which rooms your classes are in and which days you have your different subjects on.

Other points:

    If you've got an older brother or sister at the school, then ask them for advice.

    Be yourself! It sounds simple, but things will become better if you just act naturally.

    Having early nights makes a difference. You'll also find it easier to get up in the morning!

    At least 35 percent of Beijing households will be covered by family doctor service at the end of this year. All local households will enjoy the service as of 2020, according to the Municipal Health and Family Planning Commission.

    It is good that Chinese communities can expect more general practitioners(从业者)，who do not specialize in any particular area of medicine but who are able to treat the general health problems for people of all ages. By the end of last year over 8 million residents in Beijing had reportedly signed up for family doctor services, accounting for more than 40 percent of the city's permanent population.

    Since 2009 China has launched scores of programs nationwide to ensure citizens have fairer access to elementary public health services ，among which the introduction of family doctors has been one of the most successful. Some regions have issued guidelines on the promotion of the family doctor service. And four months ago, Premier Li Keqiang said in this year's Government Work Report that the service should cover at least 85 percent of the Chinese cities this year.

    The expanding coverage, however, may not guarantee more residents will be offered quality medical services.

    Family doctors in some places rarely visit the families they are assigned to, and some of them have been struggling to solve patients problems either because of their unfitness or because they have too many households to attend to. In some cases, a family doctor might be assigned to see hundreds of residents a day.

    That highlights the need to better the arrangement of medical resources and to offer proper encouragement to family doctors, who should get patients to make appointments rather than employ temporary arrangements.

    Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are excessively concerned with their own appearance and actions.

    Worrisome thoughts are constantly occurring in their minds: what kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes? It is obvious that such uncomfortable feelings must negatively affect people. A person's conception of himself or herself is reflected in the way he or she behaves, and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a profound effect on all areas of their lives.

    Shy people, having low self-esteem, are likely to be passive and easily influenced by others. They need reassurance that they are doing "the right thing." Shy people are very sensitive to criticism; they feel it confirms their feelings of inferiority. They also find it difficult to be pleased by compliment with a statement like this one, "You're just saying that to make me feel good. I know it's not true." It is clear that while self-awareness is a healthy quality, overdoing it is harmful.

    Can shyness be completely eliminated, or at least reduced? Fortunately, people can overcome shyness with determined and patient efforts in building self-confidence. Since shyness goes hand in hand with a lack of self-esteem, it is important for people to accept their weaknesses as well as their strengths. Each one of us is a unique, worthwhile individual, interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our full potential. Let's not allow shyness to block our chances for a rich and fulfilling life.
