China is starting to blacklist poorly-behaved tourists as it seeks to rescue the image of its citizens as holidaymakers.

    According to a regulation by the China National Tourism Administration (NTA) that entered effect this week, tourists will be blacklisted for offences including acting antisocially on public transport, damaging private or public property, disrespecting local customs, damaging historical exhibits on purpose or engaging in gambling or pornographic activities. Records will be kept in a two-tired system: provincial-level tourism authorities are responsible for cases under their jurisdiction（管辖区域）while the NTA will be in charge of a nationwide register. People will be .blacklisted for two years after they offend, according to the regulation.            

    The NTA said tourism authorities will inform blacklisted tourists and “propose correction measures in order to mitigate the negative impact”. It also said that tourism authorities reserve the right to report such violations to public security, customs and transport authorities as well as the central bank's individual credit department.

    The regulation comes amid (在……之中) growing concern about the ill manners of Chinese tourists both at home and abroad. In 2013, a Chinese tourist wrote his name on a relief carving in Luxor, Egypt. In December, a Chinese passenger threw a cup of hot instant noodles at a flight attendant on an international flight. Chinese tourists have been fined or put into prison for carrying prohibited items or purchasing wild animal products.

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. "There can be no doubt that our trusty bicycles have changed the way people get around our great city," Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, "Bike riding can improve people's happiness."

    One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn't have food, water, a phone, or other supplies. He was getting colder by the minute.

    Nicholas had no idea where he was. He tried not to panic(惊慌). He thought about all the survival shows he had watched on TV. It was time to put the tips he had learned to use.

    He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn't, his body temperature would get very low, which could quickly kill him.

    Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.

By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could— he huddled in his cave and slept.

    The next day, Nicholas went out to look for help, but he couldn't find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.

    Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls'survival show Man Vs. Wild. That's where he learned the tips that saved his life. In each episode of Man Vs. Wild, Grylls is abandoned in a wild area and has to find his way out.

    When Grylls heard about Nicholas'amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.

    It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.

    The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain.

    And they came across astounding (令人吃惊的) results. It was found that infants had "social brains" and focused not just on their mothers but on social life in groups as well.

    "They communicate with more than one baby at once, and show jealousy and generousness," said Professor Bradley.

    He added, "They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers."

    "A baby who has a depressed mother tends to be withdrawn (内向的), but put that same baby in a group of its peers (同龄人) and they behave and interact like any other baby."

    It was the first all-baby group study ever to be conducted. "Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach," said Bradley.

    Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney's inner west, said she often noticed what appeared to be emotional attachments developed between toddlers.

    She said, "Joel (1) months and Isabella (2) months always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing."

    A family in Florida had a happy Christmas this year thanks to two local police officers, who answered a 911 call only to discover there was no emergency at all.

    When they arrived at the house of a single mother with two children, the officers discovered the younger child, about two years old, was playing with the phone. There were no signs of Christmas or holiday cheer in the house. "They weren't smiling. It seemed like they weren't happy at all. They were missing something," Officer Paramore said. "The mother mentioned that they weren't going to have a Christmas that year. It was pretty obvious that the family was struggling," he said. "So we told each other that something had to be done."

    Paramore and his partner, Barry Ward, left the house with a plan. The next day, they went to a supermarket and bought a tree, lights and some ornaments (装饰物) with their own money. Then they returned to the apartment to deliver some holiday cheer. "They hugged the tree," Paramore said. "I was glad to see that this family was going to have something to sit around and use." The police department posted the video on YouTube, hoping to share the happy news and inspire others.

    The department has received tons of donations and phone calls from people around the country asking how they can help the family. "We are covered," said Stephanie Slater, public information officer for the Boynton Beach Police Department. "We're asking people to do good in their communities on behalf of our officers. We appreciate it very much that people are talking about this after watching the news on TV because they need to see and need to be reminded that police officers are good guys," she said. "They are human beings who have a kind heart and they do things that go unnoticed like this every day."

    Over the next decade, technology will decimate more jobs in many professions.

    Some robots already cost less to operate than the salaries of the humans they replace, and they are getting cheaper. Boston Consulting Group predicts that, by 2025, the operating cost of a robot that does welding (焊接) will be less than $2 per hour, for example. That's more affordable than the $25 per hour that a human welder earns today in America.

    Uber and many other companies are working on developing cars and trucks that don't need a driver in the driver's seat. According to the American Trucking Associations, approximately 3 million truck drivers were employed in the United States in 2010, and 6. 8 million others were employed in other jobs relating to trucking activity. So roughly one of every 15 workers in the country is employed in the trucking business. We could be talking about millions of jobs disappearing in the early 2020s.

    And then there is the "Gig Economy (零工经济)" that has some businesses moving toward part-time, on-demand employment. Uber has already done this to taxi drivers, and other technology companies are doing it to a wide range of jobs. A study by Intuit predicted that, by 2020, 40% of American workers will be self-employed, and that full-time jobs will be harder to find. We are talking about 60 million people in this category. The problem is that not only do such part-time workers lack reliable full-time jobs and sick pay, but they can't enjoy health insurance and longer-term benefits.

    The measures to be taken are to raise trade barriers. But closing the doors to foreign trade won't bring jobs back. It will only slow the global economy and hurt American exports, shrinking the U. S. economy and accelerating job loss.
