America's businesses are getting older and fatter, while many new businesses are dying in infancy.

    A study last month by the Brookings Institution found that the proportion of older firms has grown steadily over several decades, while the survival rate of new companies has fallen. In addition, young people are starting companies at a sharply lower rate than in the past.

    A new report from the National Association of Manufacturers shows a major cause: The cost of obeying government regulations has risen to more than $2 trillion (12.26 trillion yuan) annually, or 12 percent of the GDP, and this cost falls disproportionately on smaller, newer businesses.

    It's risky, difficult and expensive to start a business, and getting more so. Governments are imposing various new rules on a seemingly daily basis: health insurance, minimum wage increases and, most recently in California, compulsory paid sick days for even hourly employees. These regulations shift huge social welfare costs directly onto often-struggling small businesses, while being proportionally much less costly for larger companies.

    This is partly an unintended issue of resources—established companies can cope with new costs more easily—but it's also deliberate. For instance, big insurance companies got a seat at the table to help write Obamacare, but less politically powerful firms—like medical device manufacturers—got squeezed.

    Mature, successful corporations can employ ex-lawmakers with connections, distribute campaign contributions and even write regulations for themselves. They are also more likely to want to protect steady revenue streams than revolutionize their industry.

    Major companies that have been so ill-managed they would otherwise collapse—airlines, car companies and banks—stagger（蹒跚）on because politicians ride to the rescue with bags of taxpayer money.

    The genius of our unique system of government is the determination to protect and defend the rights of the individual over the rights of the nation. As such, the rise of a well-connected oligarchy（寡头政治）that protects big business at the expense of small business, and the established over the new, is opposite to American ideals.

    Income inequality—which is directly caused by faulty government policy—is being promoted as the reason to impose more of that bad policy. But let's be perfectly clear, we do not have a free market but one where government picks winners and losers through regulations and financial aids.

    Politics is, and always has been, about balancing competing interests seeking to benefit themselves, and that's as it should be, but the force of government should never be used to reduce competition, kill innovation or support and extend artificial monopolies（垄断）by harming the consumer, the taxpayer and the economy. Policy must breed our new and small businesses or see the as-yet undreamed of innovations that could be our bright future die in infancy.

    Traffic problems are an everyday concern in many cities, including Washington, D. C. A growing number of Washingtonians are turning to bicycles to get to and from work. In fact, the number of commuters who use bicycles has doubled in the city since 2007.

    Ralph Buehler teaches urban planning at the Virginia Polytechnic Institute and State University，popularly known as Virginia Tech. He has written a book about urban biking, called City Cycling. He says there is a reason why urban bike tiding is now becoming more popular.

    “Over the last 60 to 70 years, cities in America have been adapted to the automobile.”

    “Most cities took advantage of the money coming for the interstate (洲际)highway system, from the federal government, starting in 1956. There was a 90 percent federal match(补贴)so the cities only had to put up 10%. It was very tempting.(临时的).”

    In the years after World War Two, many Americans moved to suburban communities, just outside major cities, They decided to travel great distances to and from work in exchange for a home in the suburbs. Their cars became a symbol of freedom.

    But today, many people believe they can save money by living in the city.

    Greg Billing is with the Washington Area Bicyclist Association. “When a person makes a change from using a car to using a bike, he/she is saving anywhere between 8 or$9,000 a year.”

    Ralph Buehler says governments save money when people use bicycles. “Building bicycling facilities(设施) is much cheaper than building and maintaining road facilities or public transport.”

    Washington, D.C has also taken steps to protect bike riders. It approved a safe passing law and created areas on the road between cars and bikes.

    The United States Census Bureau says 4% of the city's workers ride to work by bike. The only city on the East Coast with more bike commuters is New York.

    A ten-year-old boy from Howell, Michigan America is being hailed (赞扬…为) a hero due to his persistence (坚持) that led to saving the life of an elderly neighbor. The chain of events unfolded late in the evening on Sunday, January 26^th, 2014 when Danny Dipietro was being driven home from hockey practice by his dad.

    That's when the young boy noticed an open garage and a figure that he believed was a dog outside an apartment near his house. Given the extremely cold weather, the young boy got a feeling that something was not right. But instead of dismissing (不予理会) it like most kids at his age would have, he insisted that his mother, Dawn, go to examine what was going on. Dawn tried to convince (使相信) Danny that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to take a walk to the area with the family dog and see if there was any truth to Danny's premonition (预感). Sure enough, as she got closer to the apartment she noticed a garage that was wide open and a bent figure, waving madly. Upon getting there, she realized that it was not a dog that the young boy had seen, but Kathleen St. Onge, one of her neighbors. The 80-year-old had slipped on some ice in her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband for help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance to arrive. Though still in hospital, the elderly woman is recovering well and grateful to Danny for his premonition.

    Texting while walking is something that most of us are guilty of. We can't help replying to that message we just received. However, while it's fun to keep up with the latest gossip, we may actually be putting ourselves in danger.

    A team of researchers from two UK universities recently found that people who use their phones while on the move walk differently than usual.

    “Recently, a person in front of me was walking very slowly and weaving (迂回行进), and I thought, 'Is this person drunk?'” Matthew Timmis, co-author of the study, told the Guardian.

    It turned out that the person was just texting. Inspired by this, Timmis and his team set out to discover the effects of phone use on how we navigate streets.

    A group of 21 volunteers were asked to walk around a simulated (模拟的) street, complete with obstacles such as a step. The participants traveled the course a total of 12 times each, either writing or reading a message, making a call, or with no phone at all.

    It took the volunteers 118 percent longer to complete the course when using a phone. They also focused on the step obstacle 60 percent more and paid attention to the travel path 51 percent more when they weren't using a phone.

    Although there were no accidents, Timmis believes we should still be aware of what's going on around us.

    “The big risk here is suddenly-appearing hazards (危险), like a pedestrian (行人) suddenly walking in front of you,” he told the Guardian. “You are not going to be able to respond to that as efficiently, which increases the risk of injury.”

    To bring attention to the dangers of “text walking”, a temporary “texting lane” was set up in Antwerp, Belgium in 2015. And earlier this year, a special crosswalk featuring flashing red lights on the ground to get the attention of texters was set up in Wuhan, Hubei province.

    “Texting while walking can lead to collisions with poles or other pedestrians. You could even be endangering your own life when you cross the street without looking up,” a spokesperson for the company that made the Antwerp texting lane told Yahoo News.

Located at Europe's biggest water park, the Galaxy Erding in South Germany, the world's first VR water slide takes the exciting experience to a whole new level by offering thrill-seekers the choice of three attractive worlds — Space, Sky, or Snow. By simply wearing a headset, riders can slide through a magical alien world, follow beautiful butterflies around floating islands or put themselves in a white winter wonderland. To make the experience even more heart-stopping, the 160-meter-long ride that lasts about 35 seconds has two uphill tracks that provide a roller-coaster-like experience.

    While the tire slide, which has been successfully tested by almost 10,000 park goers since it opened in February 2018, is impressive, the technology behind it, developed by California startup Ballast is even more so. The specially-created waterproof headsets can be worn in water up to a few meters deep, without harming the delicate Samsung Galaxy S8 mobile devices that run the custom software for the VR experiences. The headsets also charge wirelessly (无线地), allowing park operators to swap out sets throughout the day.

    The biggest challenge the company faced, however, was providing a suitable VR experience for everyone. That's because unlike roller coasters, where the speed is fixed for all riders, water slide speeds vary depending on the weight of the person. To overcome the issue, Ballast fixed  smart sensors (传感器) in important areas along the slide to keep track of the rider's progress at  all times. The information, conveyed through the headset, allows the custom software to adjust his or her location within the virtual world accordingly, making for a smooth, seasickness free ride for all.

    Though Ballast is thrilled at Space Glider's success, the company has bigger ambitions. They want to create an experience where guests will be able to swim underwater surrounded by virtual dolphins, whales, and even sharks, without wearing the heavy headsets!

    I'm a single person and live with my dog. Jed isn't just my dog. He is my family. He goes everywhere with me. So I was overjoyed last year to hear that Bunnings was allowing dogs on a leash(皮带)- into their stores.

    But no sooner had the rule come in than it was quickly repealed(撤销). A little girl in Victoria had walked up to a Jack Russell in a store and been bitten(咬伤). That was it. No more dogs.

    I don't know the whole story. But here's what I have to say: dogs bite sometimes and kids are sometimes difficult to control.

    There is nothing I love more than a kid who wants to touch Jed. But what's even better is when they ask permission first.

    I was at my local dog park last week. It's huge, with an off-leash dog area to one side and a fenced-off kids' playground a good distance away. There was a family there that morning —parents and two young girls playing near the dog area. The elder girl started crying at the sight of Jed—" puppy! There a puppy! "Jed went right up and started licking(舔)her, which only made her cry louder.

    My dog was frightened and tried to get away. The little girl ran after him, shouting loudly. The parents did nothing; they just let their kid frighten my dog and then said I should have stopped him from licking her.

    While they had a choice to play elsewhere, I did not. So I had to walk Jed away.

    "I just don't want to have to meet a dog when I go shopping," said one caller on a radio show yesterday. Look, I get that. But the thing is, I don't always want to have your kid kick the back of my seat for two hours on a plane.

    When I lived in the UK and the US, I couldn't walk through the stores without stopping to pat dogs. Why can't we follow their practice?
