I was at a loss for how to handle the fights among my kick- Many activities had been tried, but they didn't work. After reading What I Know for Sure written by Oprah Winfrey, a thought occurred to me one day.

    “Starting with Dora, I want everyone to find the chance to say 'thank you' .” I declared.

    “What?” Ashley asked. “What's going on?''

    “Just do it.”

    Naturally, the kid^ all thought I had lost my mind. I wasn't sure if they were wrong, but I pressed on.

    “Now, we're going to keep going around and everyone tells what they're thankful for.”

    Clearly doubtful and frustrated, the kids launched in, and I kept them going.

    “I'm thankful for our house.”

    “I'm thankful for my clothes.”

    “I'm thankful for my whole life and everyone in the world.”

    “What? What am I supposed to say?”

    "Keep going."

    “I'm grateful for my underwear!” Instant laughter erupted, music to my ears!

    “Great, lei it out!” I encouraged. “What else?”

And that was all we needed. The gratitude--great and small, serious and funny—came rolling out.

    “My backpack.”

    “My teachers.”

    On and on it went until every face was lit with a new kind of joy and laughter. I could sense a new feeling of peace and comfort in the air a reminder of not only our blessings, but the love we really did have for each other.

    “I'm grateful for being grateful!” Dora declared.

    “Me, too!” was the unanimous response.

    I don't remember the activities that took place the rest of the day. But it was a day when our family was transformed by two simple words: thank you. Since then, it's become a family motto.

    Two new studies suggest that modem running shoes could increase the risk of injuries to runners.

    One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot.

    Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.

They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.

    The study appeared in the official scientific journal of the American Academy of Physical Medicine.

    The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.

    They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.

    Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.

    Harvard's Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.

    But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.

    The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.

    Twelve years ago, I was a 19 -year-old guy living in the French A1ps. In February 2004, while skiing the back - country in Val d'Isere, I fell off the mountain, resulting in a right leg broken in several pieces. I was helicoptered to hospital, operated on immediately—and there started my adult life.

    Before the accident, I was on a path to what I hoped would be a career in rugby. After-wards, and participation in collision sport was gone. I found a replacement in cycling. Unfortunately, by late 2012, I tried to cycle up Mount Ventoux, but it was halfway up when the pain hit me and I gave up.

    A decision needed to be made on a next step. I had to have my lower right leg cut off. Several months later, I had my first proper weight - bearing prosthetic (假肢). I jumped on a train with my bike to Mount Ventoux. Though it certainly wasn't my quickest, I did it.

    Two weeks later, I was lucky enough to be given a running blade; I bounced on it that day and then raced my triathlon (三项全能) on the Monday. So, that was me, up and running - almost 12 years since I had last run.

    Along with my running coach, I complete a “make every kilometre count” programme of four runs per week alongside a busy cycle, swim and gym schedule. So far this year, I have raced a 10k with an unexpected personal best in January of 38:04. I have my first speed triathlon in late March before heading to North Korea to compete in the Pyongyang Marathon on 10 April.

    If my lifetime allows, I will attempt to race in every country in the world. In the meantime, I'll keep on running — and, when it hurts and I'm low on motivation, I'll remember how far I've come and how much further I've got to go.

    If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

    According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes(处理) information. It is similar to the way that exercise builds muscles(肌肉).

    The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals(双语使用者) ” who had learnt a second language before the age of five, as well as a number of later learners. Scans(扫描) showed that grey matter density(密度) in the brain was greater in bilinguals who learnt a second language at an early age. But the longer a person waited before mastering a new language, the smaller the difference. “Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.

    It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible(灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”

    The findings had the same result in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, wiring, and comprehension were all tested. The results showed that the younger they stared to learn, the better. “Studying a language means you get entrance to another world,” explained the scientists.

    The Bermuda Triangle is an area in the western part of the North Atlantic Ocean, near Florida in the USA, where a number of aircraft and ships are said to have disappeared mysteriously.

    ①The earliest suggestion of unusual disappearances in the Bermuda area appeared in a September 17, 1950 article. Two years later, published "Sea Mystery at Our Back Door", covering the loss of several planes and ships, including the loss of Flight 19. Flight 19 alone would be covered again in the April 1962 issue of American Legion magazine. In it, author Allan W. Eckert wrote that the flight leader had been heard saying, "We are entering white water. Nothing seems right. We don't know where we are." In the February 1964, the article "The Deadly Bermuda Triangle" argued that Flight 19 and other disappearances were just part of strange events in the area.

    ②Triangle writers have used a number of supernatural ideas to explain the events. One explanation refers to leftover technology from the mysterious lost continent of Atlantis. Some of the Triangle writers related the events to UFOs. This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, in which the lost Flight 19 aircrews were taken by aliens.

    ③But there are also some explanation relating to nature. For example, laboratory experiments carried out in Australia have proven that bubbles containing natural gas can sink a large ship by decreasing the density(密度) of the water. Because it has been assumed that the eruption of volcanoes(火山)may produce much natural gas, making large areas of bubbles under sea so that water is no longer able to provide enough supporting power for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without any warning.

    ④Violent weather is likely to be another reason. Powerful storms forming in tropical(热带的)waters have caused thousands of deaths and caused billions of dollars in damage. These storms have in the past caused a number of incidents related to the Triangle.
