The uninvolved dad, turning up his nose at diapering(换尿布) and too busy to bathe, dress and play with his kids, is mostly a myth(神话) , a big government survey suggests. Most American fathers say they are heavily involved in hands-on parenting, the researchers found.

    The results are encouraging and important " because others have found the more involved dads  are, the better the outcomes for their children. " said researcher Jo Jones of the National Center for Health Statistics, part of the Centers for Disease Control Prevention. She co-authored the report released Friday.

    "Times have changed," said Robert Loftus, 34, of Yonkers, NY. He quit a six-figure sales job a year ago to care for his two young children while his wife works full time. "We are trying to rethink our priorities (优先考虑的事) and family seem to be NO.1 priority while in the past maybe people were more focused on career. "

    The study involved nearly 4.000 fathers who were interviewed in person between 2009 and 2013.

◇ Key findings among fathers living with children younger than 5 :

*9 in 10 bathed, diapered, helped them use the toilet or get dressed at least several times weekly .

* Even higher numbers played with them and ate meals with them that often

* Almost 2 0ut of 3 read to them at least several times weekly.

◇Among dads living with kids aged 5-18.

* More than 9 0ut of 10 ate meals with them at least several times weekly and talked with them about what happened during the kids' day that often.

* Almost 2 0ut of 3 helped with homework several times weekly.

* About half took their kids to or from activities that often.

    Dr. David Hill, a Wilmington, N. C. pediatrician (儿科医生) said the survey reflects what he's seen among his patients' fathers. Increasingly, fathers rather than mothers take their kids to the doctor. Some "are anxious about changing a diaper, " he said.

    Census(调查) numbers show that there were almost 190,000 stay-at-home dads nationwide last year versus 93,000 in 2010. Loftus, the New York stay-at-home dad, said, "I feel fortunate to be able to be such a hands-on father.  I'm doing the most significant occupation in the world. "

    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．

    Soaping up your hands may do more than just get rid of germs. It may wash away the inner confusion you feel right after being forced to make a choice between two appealing choices, according to a new study. The study builds on the past research into a phenomenon known as “the Macbeth effect” (麦克白效应）.

    It turns out that Shakespeare was really onto something when he imagined Lady Macbeth trying to clean her conscience by rubbing invisible bloodstains from her hands.

    A few years ago, scientists asked people to describe a past wrong act. If people were then given a chance to clean their hands, they later expressed less guilt than people who hadn't cleaned.

    This finding interested W. S. Lee, a researcher. “Anything from the past, any kind of negative emotional experiences, might be washed away,” says Lee.

    He decided to test hand washing's effect on one kind of bad feeling：the tension we feel after being forced to choose between two attractive choices, because picking one choice makes us feel that we've lost the other. People usually try to calm this inner conflict by later exaggerating (夸大）the positive aspects of their choice.

    He had students rank 10 different music CDs. Then he offered students two of the CDs and told them to select one as a gift. Some students then used liquid soap. Others only looked at the soap or sniffed (闻)it. “Actually, you do not need water and soap,” says Lee.

    Later, the students again had to rank all the music CDs. People who didn't wash their hands had the normal response — they scored their take-home CD higher, suggesting that they now saw it as an even more attractive one than before. But this wasn't true for the hand washers. They ranked the music about the same. “They feel no need at all to justify (证明…正确）the choice,” says Lee.

    But the effects of it just aren't clear. Schwarz says it's too soon to know whether people should head for a sink after making a tough choice. He says washing may help decision-makers by cleaning away mental disorder. But perhaps if they don't go through the usual post-decision process of justifying their choice, they might feel more sorrow in the long run.

    Garmisch-Partenkirchen

    Garmisch-Partenkirchen, Germany, is a fascinating(迷人的) mountain town. Once two separate(分开的) towns, one Roman and the other Teutonic, the 1936 Winter Olympics forced them to become one, though the two sides still have different characters(特点).

A tiny Alaska village has experienced a boom in tourism in recent years as polar bears spend more time on land than on Arctic sea ice.

More than 2,000 people visited the northern Alaska village of Kaktovik in 2018 to see polar bears in the wild. The far north community lies in an area where increasingly higher temperature has sped up the movement of sea ice, the primary habitat of polar bears. As ice has gradually moved to deep water beyond the continental shelf, more bears are remaining on land to look for food.

Polar bears have always been a common sight on sea ice near Kaktovik, but villagers started noticing a change in the mid-1990s. More bears seemed to stay on land, and researchers began taking note of more female bears making homes in the snow on land instead of on the ice to raise their babies. U.S. Fish & Wildlife Service biologists began hearing reports of the increasing number of polar bears in the area in the early 2000s. As more attention was given to the plight of polar bears about a decade ago, more tourists started heading to Kaktovik.

 "The village had fewer than 50 visitors annually before 2011," said Jennifer Reed, of the Arctic National Wildlife Refuge. "Today we're talking about hundreds and hundreds of visitors, many from around the world each year," Reed said. Most tourists visit in autumn, when bears are forced towards land because sea ice is farthest away from the shore. Bruce Inglangasak, a local hunter who sometimes offers wildlife-viewing tours, said, "I've been offering polar bear tours since 2004." Many tourists stay several days in the village, which has two small hotels. The villagers have benefited a lot from that. In turn, they provide more effective protection for polar bears with financial support from tourism development.
