                Today, a man talked very loud on his phone on a train between Malvern and Reading, making many passengers upset. I wonder how he would react if I were to read my newspaper out loud on the train, I have never had the courage to do it, though.

     Why not give it a try? Perhaps you should take lessons on a musical instrument. The late musician Dennis Brian is said to have

asked a fellow train passenger to turn off his radio. When his request was refused, he took out his French horn(号) and started

                   to practice.

I don't see how musical instruments can help improve manners in public. Don't do to others what you wouldn't like to be done to yourself. Once, a passenger next to me talked out loud on his mobile phone. I left my seat quietly, giving him some privacy to finish his conversation. He realized this and apologised to me. When his phone rang again later, heleft his seat to answer it. You see, a bit of respect and cooperation can do the job better.

                  I did read my newspaper out loud on a train, and it turned out well. The guy took it in good part, and we chatted happily all the way to Edinburgh.

                 I have not tried reading my newspaper out loud on a train, but ,several years ago, I read some chapters from Harry Porter to my bored and noisy children. Several passengers seemed to appreciate what I did.

    A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.

    An electromagnetic field（电磁场） will pullparticles（微粒） in the smog to the ground where they can be easily cleaned.

“It's like when you have a balloon which has static（静电） and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.

    His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.

    With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.

    Roosegaarde says an indoor model device has already proven it works and is confident that the results — with the help of a team of scientistsand engineers — can be replicated outside.

  “Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”

  “We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”

    Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution.

  “This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”

    However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.

    In US, the potato is one of the most widely consumed crops. French fries are commonly found in typical American fast-food burger joints and cafeterias. French fries were introduced to the US when Thomas Jefferson served them in the White House during his presidency from 1801 to 1809. Potato chips are popular with consumers as well.

    The humble potato is more than just a kind of food. In many ways it's part of the American pop culture. Let's take a look at some pop culture potatoes.

Mashed Potato dance

    The Mashed Potato dance is a craze that began in 1962. The name of the dance came from the song it accompanies, Mashed Potato Time, performed by American R&B singer Dee Dee Sharp. The move vaguely resembles that of the Twist dance style, by Sharp's fellow Philadelphian.

Hot Potato!

    Hot Potato! is an action puzzle video game released in 2001. In the game the player must drive a bus and clear the road of alien potato beings. The potato beings are either red or blue; when two like-colored potatoes touch each other, they disappear. Over the years, Hot Potato! has received mostly positive reception from critics.

Mr. Potato Head

    Mr. Potato Head is an American toy invented by George Lerner in 1949. The toy consists of a plastic potato model and a variety of plastic parts like hands, feet, ears and mouths. In 1952, Mr. Potato Head became the first toy advertised on television. This commercial revolutionized marketing and caused a boom that solidified this toy's place in American pop culture.

    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.

    An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migrations (迁徙).

    Migratory birds (候鸟) flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. "In English-language Wikipedia (维基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States," said the lead author John Mittermeier.

    And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.

    This finding suggests new ways to monitor changes in the world's biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.

    Mittermeier is encouraged by the search results. He commented, "I think there's a concern among conservationists (生态环境保护者) that people are losing touch with the natural world and that they're not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people's Wikipedia interest closely related to changes in nature."

    Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, "By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help."

Don't ignore (忽略) the difference teenagers can make.

John Michael Thomas, 14, Florida

When John Michael Thomas decided to honor his friend and classmate Elizabeth Buckley, who died from cancer, he remembered how much she loved peacocks (孔雀).

He wanted to build a life-sized peacock fountain (喷泉) in Elizabeth's favorite park in the city. He thought it could be a place for people to relax and be inspired.

John Michael raised $52,000 to build the fountain.

Barrett England, 13, Utah

The wheels began to turn for Barrett England when he heard about Karma Bike shop, a place where young people can earn free bikes by reading and performing community (社区) service.

Barrett visited Karma's owner with his idea: He would collect and repair used bikes and donate them to the shop.

He expected to get about 10 donated bikes. In the end, Barrett received 39.

Zachary Blohm, 15, Wisconsin

The 25-year-old playground at an elementary school near Milwaukee, Wis. was so small that only 70 of its 575 students could play on it at a time.

That's when Zachary Blohm saved the day. He and some volunteers wanted to build a huge playground. To raise money, Zac planned T-shirt and bake sales, sold tickets and more. He held monthly money-raising events for more than a year. Overall, he collected $130,000 — enough to finish his project.

Jack Zimmerman, 16, New Jersey

For some people, finding a meal is as simple as opening the refrigerator. For more than 366,000 hungry kids in New Jersey, it's not that easy.

That fact didn't sit well with Jack Zimmerman, who organized a drive to lessen childhood hunger in his state. His goal: create 40,000 packaged meals that could be donated to those in need.

On game day, Jack and his volunteers started their work. After the final count, the team had packaged 47, 124 meals—well above Jack's goal.
