After spending three months in and out of the hospital with numerous health issues, Donald Austin had his leg partially cut off. He was relieved to finally be able to go home after just four days recovering from the operation. When he reached his porch, though, the joy drained away.

    Donald thought he'd be able to make it up the steps to the front door on crutches, but his strength and balance weren't as strong as he'd hoped. The wheelchair was too heavy for his wife, Jennifer Austin, to lift up the steps, even when his mom offered a hand to help. Donald ended up on the concrete, the family feeling totally at a loss. They were out of strength and out of options. Just then, a car caught the family's eyes. It had driven past once but was slowly circling back. The stranger, Steven Smith, pulled up and asked if he could help. Relieved, the family watched Smith lift Donald inside and lay him safely on a couch.

    But the Good Samaritan knew there was more to do. Smith figured this wasn't the only time Donald would need to climb those steps. So the next day, Smith, who's an ordinary worker, came back and asked if he could build a ramp(斜坡) in front of the house. With his dad and a couple more helping hands, Smith set up a ramp over the steps to make the home wheelchair accessible. The act of kindness brought the family to tears.

    “This stranger has saved the day for us twice within 24 hours. He also brightened our spirits that had become increasingly dimmed over the difficult months,” Jennifer wrote on Facebook. “There is a sense of optimism back in our home because of his kindness.”

    Runners who encounter visual and auditory distractions (干扰)may be more likely to suffer leg injuries, according to research by the Association of Academic Physiatrists in Las Vegas. Runners often seek distraction from the task at hand. Whether it be music, texting, daydreaming, taking in the sights, or propping a book up on the treadmill(跑步机), more often than not a distraction is welcome. But, researchers from the University of Florida have recently discovered those distractions may lead to injury.

    Daniel Herman, MD, assistant professor at University of Florida, and his team conducted research on the effects of visual and auditory distractions on 14 runners to determine what effect these distractions would have on things such as heart rate, how many times a runner breathes per minute and how much oxygen is consumed by the body.

    The runners were all injury-free at the time of the study and ran 31 miles each week. Dr . Herman's team had each participant run on a treadmill three separate times. The first time was without any distractions. The second time added a visual distraction, during which the runners concentrated on a screen displaying different letters in different colors with the runner having to note when a specific letter-color combination appeared. The third time added an auditory distraction similar to the visual distraction, with the runner having to note when a certain word was spoken by a certain voice.

    When compared to running without distractions, the participants applied force faster to their left and right legs called loading rate, with auditory and visual distractions. They also experienced an increased amount of force from the ground on both legs, called ground reaction force, with auditory distractions. Finally, the runners tended to breathe heavier and have higher heart rates with visual and auditory distractions than without any distractions at all.

    "Running in environments with different distractions may unfavorably affect running performance and increase injury risk," explains Dr. Herman. "Sometimes these things cannot be helped, but you may be able to minimize potentially cumulative(累积的) effects. For example, when running a new route in a chaotic environment such as during a destination of marathon, you may want to skip listening to something which may require more attention - like a new song playlist."

    Dr. Herman's team will continue to investigate the potential relationship between distracted running and leg injuries, and any effect this relationship has on different training techniques that use auditory or visual cues.

    Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I'd like to draw your attention to a few of our laws.

    The first one is about drinking. Now, you may not buy wine in this country if you are under 18 years old, nor may your friends buy it for you.

    Secondly, noise. Enjoy yourselves, but please don't make unnecessary noise. We ask you to respect other people who may wish to be quiet.

    Thirdly, crossing the road. Be careful. The traffic moves on the left side of the road in this country. Use pedestrian crossings（人行道） and don't take any chances（冒险） when crossing the road.

    My next point is about rubbish. It isn't a law to drop rubbish in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a dustbin.

    Finally, about smoking. It is against the law to buy cigarettes if you are under 16.

    If you request any help, you should contact the police, who will be glad to help you. You can call, write, or directly go to ask any policeman.

    Judy Wright and her husband decided to move closer to their son, Chris, who lived in Georgia. About a month after the move, Judy fell ill, suffering from her ongoing battle against Parkinson's disease.

    Her condition worsened rapidly and she required medical care at home. The family hired a nursing aid who canceled at the last minute. Instead, a woman named TunDe Hector showed up in her place.

    One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger had helped her with a kind gesture. She had run out of gas, and with only$5 in her pocket, was walking to a gas station, gas can in hand. A man saw her walking and turned his car around. He paid for her gas and gave her all the cash left in his wallet. Upon hearing the story, Judy's son, Chris, took off his hat and said, "That was me!” He was the stranger that had helped TunDe on that difficult day.

    During the care of Judy, the Wright family learned about TunDe's family and her own dream. The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse.Her tuition was past due(逾期) and she had a family to care for, but she was determined to achieve that goal for herself and her family.

    Judy died on July 9,2017. Instead of flowers, her family asked mourners(悼念者) to donate to TunDe's education , to assist her in paying for her nursing school. In less than a week, they raised more than $8,000 and presented her with the surprise check.
