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'."

    When he was driving home one evening on a country road, he saw an old lady, stranded(抛锚的) on the side of the road. He stopped in front of her car and got out. Even with the smile on his face, she was worried. He looked poor and hungry. He knew how she felt. He said' “I am here to help you, madam. Why don't you wait in the car where it's warm? By the way, my name is Joe.”

    She had a flat tire(轮胎). Joe crawled under the car, changed the tire. But he got dirty and his hands hurt. She could not thank him enough and asked him how much she owed him. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the help they needed, and Joe added, “And think of me.”

    She drove off. A few miles down the road the lady saw a small restaurant. She went in. The waitress had a sweet smile, and was nearly eight months pregnant(怀孕) The old lady wondered how someone like her who seemed poor could be so kind to a stranger. Then she remembered Joe. After the lady finished her meal, the waitress went to get her change from a hundred-dollar bill. But she stepped right out the door.

    When the waitress came back, she noticed something written on a napkin(餐巾), “I am helping you because someone once helped me. If you really want to pay me back, here ‘s what you do--Do not let the chain of love end with you.”

    That night when she got home, she was thinking about the money and what the lady had written. She and her husband needed money with the baby due (预产期)next month. She knew how worried her husband was, and as he lay sleeping next to her, she whispered, “Everything's going to be all right. I love you, Joe.”

    Kung fu is one of a number of Chinese martial arts designed to improve the body and the mind. It is perhaps one of the most widely known martial arts, because many films include its techniques. There are hundreds of styles taught all over the world, although they can be loosely divided into two camps: Shaolin style kung fu, and other techniques, some of which have a history that outdates the Shaolin order.

    Shaolin kung fix has its origins in the fifth century. Like some other martial arts, it began in religious temples, where the monks sought a mind and body discipline (训练方法). In addition to the fighting style, it also includes mental exercises and religious practices designed to balance the whole body.

    Shaolin temples resembled universities, integrating a wide range of subjects of study. Therefore, traditional Shaolin styles such as Wing Chun, Crane, Praying Mantis, and Hung Gar took knowledge from fields outside martial arts, such as the healing arts and meditation. Supporters for Shaolin styles believe that they are more rounded martial arts styles, and that learners will benefit from them on a whole body level.

    Other fighting styles, some of which predate the Shaolin style, are also lumped under the kung fu umbrella. They include Pa-Kua, Eagle Claw, and Eight Drunken Immortals styles. These disciplines are not considered to be Shaolin style because they did not originate in temples and are focused primarily on fighting techniques.

    Whether Shaolin or otherwise, kung fu is characterized by self defense strategies that turn the energy of an attacker against him or her. Although the techniques may vary, most styles teach throws, kicks, punches, and the use of weapons. In addition to the physical discipline, most place a great importance on respect, honor, and living a balanced life.

The summer I turned 16, my father gave me his car — a gift wasted on me at that age. The important thing was that Hannah and I could drive around.

    Hannah was my best friend, a year younger but much taller, almost five foot ten. "Hannah's a knockout," my mother always said. And that summer she signed with a modeling agency. She was already doing runway work.

    A month after my birthday, Hannah and I went to the movies. On the way home, we stopped at the McDonald's drive-through, putting the fries on the seat between us to share. "Let's ride around a while," I said. It was a clear night, full moon slung low over the desert. Taking a turning too fast, I plowed (撞)through a neighbor's wall and drove into a full-grown tree.

    We were taken in separate ambulances. I'd cracked(使裂开)my cheek bone; Hannah's forehead had split wide open. End of her modeling career. What would I say to her?

    When her mother, Sharon, came into my hospital room, I started to cry. She sat beside me and took my hand. "I rear-ended(追尾) my best friend when I was your age, "she said, "I totaled her car and mine."

    "I'm so sorry." I said.

    "You're both alive," she said, "The rest is window dressing. I forgive you. Hannah will too."

Sharon's forgiveness allowed Hannah and me to stay friends throughout high school and college, to be at each other's weddings … The scars are so faded that no one else would notice, but in the sunlight I can still see it just below her hairline — for me, a mark of grace(优雅).

    "Our aim is to take our art to the world and make people understand what it is to move," said David Belle, the founder of parkour.

    Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.

    Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the barriers in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

    Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

    Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."

    Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself.

The age of technology is a great and convenient thing, but it does have effects on us in many different ways.

It causes long-term memory loss. Thanks to Baidu, we don't really have to remember much of anything. Questions are answered at the drop of a hat because Baidu is all-knowing! Is that a good thing, though? People aren't digging through their brains anymore to find answers. Here's the good news: we can still exercise our long-term memory by simply thinking before we Baidu. If we don't want to go down that road, we can search Baidu for some memory games to play. Turn Baidu into an asset instead of an enemy.

It makes us lack patience. Baidu gives us what we want. Everything is instant. In fact, if we have to wait for even a handful of minutes for anything, we start losing our minds. This idea of instant satisfaction carries through to many other aspects of our lives, too, like when we go out to eat, drive in traffic, or even deal with workplace accidents. Instead of using Baidu to lessen our anger, try searching for some mindful meditations (沉思).Focus on our breath and realize everything doesn't have to move at lightening speed. We can actually listen to some peaceful spa or meditation music on our Pandora, too!

It wastes our time. Be honest, how much time are we spending on Baidu every day? Whether we're doing research for our own personal needs, buying clothing, or writing a research paper, we all spend a ton of time on the trusty Internet. Are we always being efficient with this time? For the sake of our precious time, if we haven't used Baidu Drive, we should. Keep spreadsheets, text does, PDFs, slideshows, and even recordings exactly where we can easily find them. Keep a running list of websites we know we'll revisit.

Overall, things are different these days. Yes, there are noticeable negative side effects because of the Baidu invasion, but we don't have to fall into that trap. Stay sharp and don't let ourselves become imprisoned doing the Baidu god's bidding.
