Music is magic! Music speaks louder than words and it is a “language” that the whole world can understand. A piece of music can produce a response in the heart and mind. Like feeling an electrical current or receiving a personal radio signal, music has a spiritual effect on a person. Different kinds of music influence people in different ways.

    I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke... even our culture. The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.

    Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.

    Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images—matching the music that you are listening to.

    Hilversum is a medium-sized city between the major cities of Amsterdam and Utrecht in the Gooi area of North Holland, the Netherlands. Unlike most of the Netherlands, Hilversum is actually in a hilly area with the soil mostly consisting of sand. Once called the Garden of Amsterdam, it still attracts travelers to come over to cycle and walk through the surrounding forests. They visit it for a relaxing day off from the urban madness. For Dutch people, Hilversum is all about textile (纺织) and media industries, and modern architecture.

    In history, Hilversum was largely an agricultural area. Daily life was marked by farming, sheep raising and wool production. A railway link to Amsterdam in 1874 attracted rich traders from Amsterdam to Hilversum. They build themselves large villas (别墅) in the wooded surroundings of the town. One of the families moving in was the Brenninkmeijers, currently the wealthiest family of the Netherlands. They moved in after big success in the textile industry and aided a substantial textile industry in Hilversum. But the textile boom lasted only several decades. The last factory closed in the 1960s.

    The change to a media economy started in 1920, when the Nederlandse Seintoestedllen Fabriek (NSF) established a radio factory in Hiversum. Most radio stations called in the large villas in the leafy areas of the town. Television gave another push to the local economy. Hilversum became the media capital of the Netherlands, and Dutch televison stars moved into the leafy neighborhoods surrounding the town.

    In the early 1900s, modern architcts W.M. Dudok and J. Duiker placed hundreds of remarkable buildings in Hilversum. These modern architectural masterpieces (杰作) are so many that Hilversum almost feels like an open air museum. Dudok alone shaped most 20th century Hilversum and approximately 75 buildings in 1928-1931. It has wide international fame and is included in many architecture textbooks. The building has a remarkable shape and looks like a combination of “blocks”. Actually, one may start his journey of modern architecture by walking or biking the W.M. Dudok Architectural Route in Hilversum.

“Hi, Mrs. Grady,” said Mark when their neighbor opened her door. “Would you like us to shovel（铲） your sidewalk and driveway?” Shoveling was Jamie's idea, a way to earn enough money for the new Ocean Kingdom video game that came out the next day.

    Mrs. Grady was happy, “That would be wonderful, boys. I think the job is getting to be too much for me.”

“It will cost 10 dollars,” Jamie said. “If that's OK,” Mark added.

“Oh dear,” Mrs. Grady said disappointedly, “I haven't been able to get to the bank. I can offer homemade cookies, but I realize that's not what you had in mind.”

Mark was going to say that Mrs. Grady could pay them another time, but Jamie cut him off. “We'll come back later.”

Mrs. Grady doesn't look like the person who'd come to Mark's rescue last summer when Mr. Dunn's dog Goldie had just wanted to play, but Mark didn't feel comfortable around big dogs. He wanted to call for help, but his tongue seemed locked behind his teeth. Then Mrs. Grady's front door had flown open. She must have seen him from across the street. “Hold on, Mark. I'm coming!” “Goldie” she'd called. As soon as Goldie had turned her head, Mrs. Grady had slipped between Mark and the dog. She wasn't much taller than Mark, but she'd stood firm as a rock in front of him. “Goldie, go home!” Then she'd swept her broom to hurry the dog along. “Get!” Goldie had obeyed.

When Mark showed thanks to Mrs. Grady, Mrs. Grady laughed. “It was nothing. Good neighbors watch out for each other, don't they?”

And now Mrs. Grady needed Mark as much as he'd needed her last summer. He smiled and waved at Mrs. Grady, then his shovel deep into the snow.

“Hey!” Jamie shouted. “What are you doing?” Mark couldn't explain about Goldie and watching out for neighbors. “I like Mrs. Grady's cookies,” he said.

Let E-bikes Power New York's Transit Future

    Providence, R. I., just became the 13th city to develop an electric-assisted bike-share system, which runs or is developing bike-share networks in cities across the United States. Ironically, the Brooklyn-based company cannot operate in its hometown of New York City,due to the wrongheaded ban on electric bicycles.

    In many major cities in the U. S. and abroad, e-bikes are flourishing and helping to solve major urban challenges. Stockholm is adding 5, 000 e-bikes to its bike-share system. UPS is delivering packages in Hamburg using electrically-assisted cargo tricycles. And San Francisco's DoorDash food delivery service has found e-bikes to be the best mode to navigate heavy traffic and limited parking.

    In striking contrast, New York City insists e-bikes are banned under law. More than 900 e- bikes were seized and more than 1, 800 summonses（召回）were issued by the New York Police Department in 2017,following Mayor de Blasio's decision to limit e-bike usage, despite the fact that no data or records exist to show e-bike-related safety incidents.

    Who does the e-bike restriction hurt? The e-bikes seized in 2017 primarily belonged to food delivery workers, who are immigrants from Asia and Latin America. New Yorkers love their delivery: A new study from the New York City Department of Transportation found that more than half of city residents receive food deliveries at least a few times per month."

    In fact, the top three neighborhoods for e-bike summonses-the Upper East and West Sides and East Midtown-also consisted of more than 70% white residents. It's difficult to divorce the penalty of workers of color from the predominantly white, rich neighborhoods to whom the meals are delivered.

    It is true that the rush to maximize delivery numbers leads to higher speeds and potentially dangerous biking. To that end, the city should improve and enforce safe cycling and expand bicycling infrastructure to ensure safe passage for cyclists and pedestrians.

    Outside New York, cities and companies are finding that e-bikes are convenient, have low carbon footprints and require less space than cars on city streets. As New York City seeks to improve traffic, better air quality and encourage active modes of transportation, it is confusing that a mode that checks all of those boxes would be outlawed.

    The city must stop pedaling backwards on both workable transportation modes and the racially-charged policies surrounding them. It is time for New York City to embrace e-bikes as the very useful, worker-enabling, convenient and environmentally-forward mode that they are.

    Tattoos (纹身) are becoming more and more common. But they are not a new thing. Scientists have found some frozen bodies from around 3,000 BC and their skin shows the marks of tattoos. For example, Otzi, the Iceman (the oldest body ever found), was discovered in the mountains of Austria. He had many different lines and crosses tattooed on his back and his knees.

    The most common places to get tattoos are the tops of the arms for men and the bottoms of the backs for women. Any mark can be used but there are some common ideas. Some people like to get animals, like dragons, birds and tigers. Other people like to get something written in a foreign language, so Chinese and Japanese words are common in America and the UK. If you can't read the language, make sure you get someone to check what they represent because the tattoo artist could write anything and you would never know.

    It is a big decision to get a tattoo because they are very difficult to remove. It is possible with expensive laser surgery (激光手术) but this is very painful and amazingly expensive and the skin will never be perfect afterwards. You want to do a test, to see how you look with a tattoo, you can get a temporary tattoo which disappears after about a month. This kind is very popular in India, where people often have them for festivals.

    In some countries, such as Japan and Korea, tattoos are still connected with law-breaking activities and it isn't normal to see a tattoo in public. In many places of Europe and America, most people don't care very much whether you have a tattoo or not, though there are some types of job where they don't like tattoos. But some Presidents of the USA have had them.

    If you're a fan of smart technology, you may have had some sleepless nights lately.

    That's because Alexa, the artificial intelligence (AI) behind US company Amazon's Echo smart speakers, has been "letting out an automatic, creepy (令人毛骨悚然的) cackle," for no apparent reason, according to BBC News.

    Many social media users shared their stories of Alexa scaring them with the seemingly unprompted laugh.

    "Every time Alexa laughs, an angel dies," Tesla and SpaceX founder Elon Musk joked on social media.

    On March 7, Amazon released an update that fixed the problem, saying that the laugh was triggered (引发) by Echo devices mistakenly thinking that users had said the command "Alexa, laugh".

    However, what should have been a funny story raised the ongoing topic of man versus machine.

    With the rise of artificial and robotic technology, "Digital machines have started to demonstrate (展示) broad abilities in pattern recognition, complex communication, and other fields that used to only belong to human," wrote Erik Brynjolfsson and Andrew McAfee in their book The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Technologies. They believe that AI will "do more and more, and our lives will get better".

    However, ever since the earliest days of AI, there have been concerns that some day, software will take over the world, leaving the fate of humans unknown.

    "With artificial intelligence we are summoning (召唤) the demon ," Musk told students during a meeting at MIT in 2014. "If I had to guess at what our biggest existential threat is, it's probably that. So we need to be very careful."

    Many scientists have shared the same concern. The late British physicist Stephen Hawking said at a technology conference in Portugal in November that "computers can, in theory, imitate human intelligence, and exceed it… AI could be the worst event in the history of our civilization." If creators are to safely control AI, however, Hawking suggested that they "employ best practice and effective management".

    "I am an optimist and I believe that we can create AI for the good of the world," he said at the conference. "We simply need to be aware of the dangers, identify them, employ the best possible practice and management, and prepare for its consequences well in advance."
