Traffic problems are an everyday concern in many cities，including Washington，DC．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，calledCity Cyclin . g．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 adapted to the automobile．”

    “Most cities took advantage of the money coming for the interstate 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．”

    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 is much cheaper than building and maintaining road facilities or public transport．”

    Washington，DC 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．

    Recently some articles claim the word “selfie” as one of the most annoying words. But I'd like to offer that maybe it isn't not so bad.

    The “selfie” is used to describe the self taken photo, often from a smart phone. Women and men alike adorn their Instagram, Facebook and Twitter accounts with these pictures, sometimes with puckered lips or large smiles. In fact, the selfie has become so widely known that over 31 million photos on Instagram are captioned with the selfie.

    Let's think about it. Someone takes about 10 seizes each time they do, and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn't that beautiful? In that one picture, someone has even him or herself confidence.

    Self-image is important. In society today, we are so often consumed with what society tells us is perfect. But maybe, with that one selfie, we feel like we fit that bill. We feel handsome, beautiful, confident, smart, happy and content. For that moment, everything bad or terrible that has ever happened to us is erased, because that smile or that pucker is what gives us the determination to love ourselves.

    I saw a spoken word poem recently and the young man said: If I ask you what you love the answers will most likely roll off your tongue. You love to read. You love to write. You love birds, music, tattoos… Your mom, your brother, your sister, your daughter, your best friend, your dog. How long do you think you could go on and on before you said “I love myself”？

    That statement hit me like a ton of bricks. I've struggled with confidence all of my life. I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However, the selfie does deserve some credit for allowing individuals to express themselves. Pamela Rutledge agrees, stating, “There are many more photographs available now of real people than models.”

The World's Coolest Places

    There's nothing wrong with a relaxing week at the beach. But travel can also be an education, a step toward empathy(共鸣) and international understanding, so for those longing to escape the crowds this summer, encounter new worlds and return with a tale, here're a few little-known travel destinations I recommend.

The American Bystander

    On a humid subway ride into work a few days ago, a woman on the other end of my car had a seizure (病情突然发作). All of a sudden, I heard her let out a painful sigh as she collapsed. For several minutes, the train continued down the track, and everyone in the car just stared at the woman. Finally, at the next stop a man informed the operator of what had happened and called 911. Luckily the woman came to herself as the EMTs carried her off the train. Ever since, I've been puzzled by the same question — why didn't anyone do anything? And more importantly, why didn't I do anything?

    We've learned about the commonly referenced bystander effect—a psychological phenomenon in which individuals will avoid offering help to a person in need when other people are present. The bystander effect is attributed to two different psychological processes: social influence—individuals in a group will monitor and imitate other group members' behavior—and shift of responsibility—individuals will cease to help because they believe that someone else will.

    Even though most people probably haven't witnessed a woman having a seizure on the subway, I'm sure if asked, anyone could think of a time when they could have helped and simply didn't. In fact, I know that we have all experienced the bystander effect, because I believe it is one of American society's most common headaches.

    Anyone who follows the news can tell you that most of what we hear or read about these days is another death or another hate crime committed right in our own country. Consider the most recent theatre shooting in Nashville. The headlines read Another Theatre Shooting, Gunman is dead. When we read that headline or heard it on the news, most of us just acknowledged how sad it was, then told ourselves that there is nothing we can do to help and assumed that someone else would.

    If America is just one large group of witnesses, all while telling ourselves that someone else most certainly will step in, how can we hope to shake the hold of this social psychological spell? The solution lies solely within us, to know the difference between doing what is justifiable and doing what is right, helping those in need when we have the means and opportunity to do so.

    I want to be like the man on the subway who told the operator about the woman's seizure, because as soon as he did, people followed suit and offered help. We have the power to choose whether to justify passivity or actively decide to do the right thing, and as a society I believe we ought to break free from our psychological tendency to just stand by.

    Reality TV show has been charged with making the nation silly, but a study suggests part of the show could be good for children.

    Massey University PhD student Jacinta Hawkins looked at the influence of TV programs on kids' health knowledge, attitudes and behavior. She said programs which showed overweight people on TV is making children say "I don't want to grow up like that'."

    The research was part of Ms Hawkins' paper on how schools improve health. She spoke to 92 children, ages from 7 to 13, from six Auckland primary schools to find out how they received information on nutrition and physical activity. Some said they learnt from TV news programs, but most of them mentioned reality shows such as Fat Chance, Honey We're Killing the Kids and Downsize Me.

    "Earlier studies had looked at the effect junk-food advertising had on children," Ms Hawkins said, "but messages within TV programs had not been explored. Children from the six schools largely recognized program content, rather than advertising, as a source of food and physical activity messages. They are learning habits of eating and exercise from TV programs. "

    The children also recognized that their parents had a role to play in shaping health behavior. Talking about Honey We're Killing the Kids, which shows how people will look if they continue with good habits, children said they developed attitudes from their family's habits. MMs Hawkins said children remembered what they had seen and thought it was the parents' duty to lead by example.
