In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five fays off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I'd hitch a ride (搭便车).

    I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn't give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured （使…放心）me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.

    Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the kindness I'd been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.

    After a few moments of small talk, the man said to me, “You haven't changed a bit, even your red hair is still the same.” I couldn't remember where I'd met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.

    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.”

    Two deer jumped out in front of 16-year-old Amanda Floyd's car. She stepped on the brake, stopping the car just in time. But later, she started texting. Distracted (分心的)，Amanda turned left and right, then crashed into another car. Luckily, she wasn't in a real car--she was in a driving simulator (模拟器) at Roosevelt High School, Ohio, US. “I never really realized that cars make a turn that much," Amanda, a Junior, said. She added that she wouldn't text while driving anymore.

    The Ohio Department of Transportation (ODOT) and State Highway Patrol brought the simulator to the school. They said they wanted to help students learn about the danger of driving while drunk, while texting, or while talking on the phone.

According to the National Highway Traffic Safety Administration, distracted driving claimed 3,4501ives in2016 alone. Experts believe the actual figure is probably higher.

The simulator is basically a computer program. Like many computer games, it was a hit with the students. They lined up and crowded around to watch each other take turns. The simulator has a steering wheel! (方向盘) ,brake and gas pedal (油门踏板) . It is made up of three large computer screens on a table.

    Students choose a distraction, such as driving while drunk or texting. They always crash, of course. Then, they are pulled over by the police to be taught the bad results of their driving: how much damage they've caused, what their fine is, if anyone died in the accident, and if they're going to go to prison.

    "It teaches how to drive without being on the road," said Shante Thompson, 16. She had just crashed into a deer.

    ODOT spokesman Justin Chesnic said hundreds of kids have gone behind the wheel so far. He said even more have benefited from watching their classmates. "Driving is such a major responsibility, so take it seriously" he said. “Put away your cellphone. A lot of the accidents out there are because of distracted driving. It can not only change your life, but it can change someone else's life forever. The results are serious."

    Winter is the perfect time to see Washington in a different light. The crowds have thinned, and those humid 95-degree days are long gone. And the National Zoo is a different experience because of 500,000 bulbs that illuminate the annual Zoo-lights celebration.

    Eco-friendly twinkly lights will decorate zoo walkways, trees and buildings. Sculptures featuring popular zoo residents, including elephants and giant pandas, light up in time to music.

    If walking and watching isn't enough excitement, head to Lion & Tiger Hill, home to a 150-foot-long snow-less tubing run. Rides on the trackless train and the carousel also will be available.

    Don't forget to visit a few of the zoo's real animals. The Kids' Farm, Reptile Discovery Center, Small Mammal House, Think Tank (orangutans) and Great Cats exhibit will be open in the evening. There's no guarantee, however, that the animals will be as lively as the humans in attendance.

    When: Friday to January 1 (except December 24-25), 5 to 9 p.m.

    Where: 3001 Connecticut Ave. NW, Washington, D.C.

    How much: Admission is free; limited parking is $22. Charges for tubing, train rides and carousel rides.

    For more information: A parent can visit nationalzoo.si.edu/events/zoolights.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning experiences increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.
