The associates I hired in my bicycle and lawn mower shop like myself were never perfect; however, they were excellent. Working with them as they improved taught me new ways to show forgiveness, understanding, and patience.

    One day the placement officer asked me to interview a young man who was having trouble finding a job. He told me that David was a little shy, did not talk much and was afraid to go on with interviews. He requested that I give David an interview just for practice. He plainly told David that I had no positions open at the time and the interview was just for practice.

    When David came in for the interview, he hardly said a word. I told him what we did at the bicycle shop and showed him around. I told David to keep showing up because the number one thing an employer wanted in an associate was dependability.

    David was very quiet (he was evaluated as a slow learner in school). Every ten days or so, for weeks after the interview, David walked into the bicycle shop and stood by the front door. He never said a word, just stood by the door.

    One day, shortly before Christmas, a large truck came to the shop, packed with 250 new bicycles. It had to be unloaded right away or the driver would leave.

    It was raining. Some of my workers (without physical limitations) chose not to brave the weather to get into work, so I was short-handed. It seemed everything was going wrong and on top of it, David came in the front door and just stood there. I looked at him and shouted, “Well, all right! Fill out a time card and help me unload this truck!”

    David worked for my bicycle shop for eighteen years. He came to work every day thirty minutes early. He could talk; however, he rarely chose to. He drove my truck and made deliveries. The customers would praise David, saying, “He doesn't talk, but he really shows you how to operate a lawn mower!”

    The weather outside might be freezing at home, but that doesn't mean you have to spend the winter shivering. Instead, grab your bathing suit and sunscreen and head to these sunny spots that offer the best warm-weather getaways for every interest.

    The best city beaches: San Juan, Puerto Rico

    Being able to relax on a warm sandy beach in the middle of the winter is obviously a dream getaway, but not everyone wants their sand and surf to be hidden in a remote comer of an island. Instead, head to the sizzling（炎热的）city nightlife of San Juan, where the streets of chic Condado back right into the palm trees and lapping waves of the Atlantic beaches. Top chefs, stylish hotels, bars ， clubs, and shops are all just steps away from the tropical beaches. And since Puerto Rico is a United States Commonwealth, it's one of the easiest islands in the Caribbean to visit since you won't need a passport, have to change money, or even worry about your cell phone working. Puerto Rico is also one of the best tropical vacations you can take without leaving the United States.

    The best swimming holes: Riviera Maya, Mexico

    What's better than diving into the salty sea? Submerging in the crystal clear and salt-free waters of the naturally occurring limestone cenotes of the Riviera Maya and Yucatan Peninsula. Spend a sunny day exploring these natural cave pools filled cool filtered water that springs from the ground below and the lush palm forests that surround them. Then head back to the perfectly located Fairmont Mayakoba for comfortable rooms and modem Mexican cuisine.

The amazing dolphins will probably make you want to hit the waves yourself, which won't be a problem since the beautiful white sand beaches here boast 361 days of sunshine per year.

    The national environmental watchdog has declared that boosting efforts to cut air pollution in northern China, especially winter smog from the burning of coal, is a mission for this year.

    Burning coal for winter heating has been listed as one of the primary causes of air pollution, Chen Jining, minister of environmental protection, said on Monday at the annual meeting on environmental protection in Beijing.“As much as 60 percent of smog content is caused by coal burning in the starting phase of each smog”, said Fang Li, an official with Beijing's Environmental Protection Bureau. Therefore, Beijing has declared that it will wipe out coal use in its most rural areas by 2020.

    To start with, Beijing will replace coal-fired heating stoves with those powered by electricity or gas in 400 villages this year, before taking the campaign to the districts of Chaoyang, Haidian, Fengtai and Shijingshan by 2017,said Guo Zihua, a municipal rural development official. Beijing's downtown districts of Dongcheng and Xicheng eliminated coal burning last year, officials said.

    The capital and other places in northern China experienced several smog alerts in November and December, when peak readings were many times higher than the national safety level. Obviously, the situation is deteriorating, and will become a norm. So the government came up with a “smog subsidy (津贴)” for those who work outdoors, and 95 percent of the respondents to a survey support it.

    The Trade Union in Zhengzhou City surveyed subscribers to its official WeChat account and found that 88 percent of nearly 400 respondents said priority should be given to outdoor workers on smoggy days But 9 percent said air pollution affects everyone so it would be unfair to only address the concerns of people who work outdoors.

    Over half of the respondents think the extra subsidy, if applied, could come in the form of protective tools or cash. Twenty-two percent said money is the easiest way. To finance the proposed subsidy, 53 percent think the government and companies should jointly pay the bill, while 44 percent said central and regional governments should be responsible.

    Photos of eight-year-old Wang Fuman, nicknamed by “Snowflake Boy” in Yun Nan, shared by his principal on Tuesday, showed the boy has a red face from the low temperatures and apparently did not wear enough clothes to keep warm. He also suffered from frostbite. He stood alone with his white hair and eyebrows while other classmates behind were clearly amused and laughing. The picture drew widespread attention around the whole world. Many netizens (网民) were sympathetic to the boy's difficulties, with many Mircoblog users giving comments under the report.

    Just after the report, a donation of 100,000 yuan was sent to his Primary School. Constantly, help still pours in for the Chinese boy. But the local authorities call on others to pay attention to other similar rural areas and give them timely aid. In China, there are still so many children just like Fuman living by himself with parents migrating to cities to make a living.

    There is an English saying that says, "Let Sleeping Dogs Lie." It means not bringing up an old problem. Researchers in Hungary have found another reason to let dogs keep on sleeping. It seems the animals are learning while they sleep.

    The Hungarian researchers placed tools on the dogs' heads to know about electrical activity in the brain. The brain activity, called sleep spindles(梭状波), takes place in human begins, and has been connected with learning. The researchers hope to understand how the dogs' ability to learn and remember changes as they get older. The study may help them understand how human brains change as we age.

    The researchers found differences between male and female dogs. Iotchey, a researcher, says the females appeared much better at learning new things. Female dogs have about twice as many spindles per minute as male dogs, they also happen to be the better learners, and they memorize the task much better. But it was harder for all the older dogs to remember things, especially when several things were happening at the same time.

    DoraSzabo also studies sleep spindles. Szabo is a neuroscientist in a university in Budapest. She says the older dogs have fewer spindles and are easily cheated. "If you first hide the reward into one bowl, then in another and in another, they get lost after a while. So their performance is going down, and they are getting poor in solving new problems."

    Researchers hope the study will not only help understanding of learning ability and memory changes in dogs, but also the aging of humans. Senior Researcher EnikoKubinyi adds that the aging dogs suffer from the same problems as humans who are aging. “Among very old dogs, up to two thirds of them show signs of dementia(痴呆), and this dementia is really very similar to that of humans, so we could use dog as a natural model of human aging."
