Why do Americans struggle with watching their weight, while the French, who eat rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.

    According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed (挤进) between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.

    After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.

    In spite of (尽管) all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity (肥胖)—or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young refuse older traditions, the obesity rate among French children has reached 17% — and is growing.

    Do students learn as much when they read digitally as they do in print? Investigators have been trying to determine whether students do as well when reading an assigned text on a digital screen as on paper.

    A number of researchers have sought to measure learning by asking people to read a passage of text, either in print or on a digital device, and then testing for comprehension.

    Most studies have found that participants scored about the same when reading in each medium, though a few have indicated that students performed better on tests when they read in print.

    Since in standardized testing, reading passages and answering questions afterwards may tell us little about any deeper level of understanding, some researchers are beginning to pose more subtle questions.

    When people were asked to read d story in print or on a digital device and then to reconstruct the plot development, the answer is: Print yielded better results. When people were asked to read by choosing how much time to spend on each platform, the researchers found that participants devoted less time to reading the passage on screen and performed less well on the following comprehension test.

    So, how does the learning question relate to educational goals?

To become skilled in critical thinking, students need to be able to handle text. The text may be long, complex or both. To make sense of it, students cannot skim, rush ahead or continually get distracted. So, does reading in print versus on screen build critical thinking skills?

    When asked in which medium they felt they concentrated better, 92 percent replied “print”. For long academic reading, 86 percent favored print Participants were also reported to be more likely to reread academic materials if they were in print

    What's more, a number of students indicated they believed print was a better medium for learning. By contrast, in talking about digital screens, students noted “danger of distraction” and “no concentration”.

    Evidently, it's not too hard to tell that a pattern did emerge: Print stood out as the medium for doing serious work.

    Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.

    Members go on the site and register the books they own and would like to share. BookCrossing provides an ID number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

    Bruce Pederson, the managing director of BookCrossing, says “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”

    Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

    People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

    BookCrossing is part of a trend among people who want to get back the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. "There can be no doubt that our trusty bicycles have changed the way people get around our great city," Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, "Bike riding can improve people's happiness."

    On a flight from Dallas, Texas, to Cincinnati, Ohio, to visit a friend in 2013, event planner Paige Chenault daydreamed about the grand birthday parties she'd throw for her daughter one day. (Paige was five months pregnant at the time.) Then, flipping through a magazine, she saw a photo of an impoverished Haitian boy, skinny. "I thought, this kid has nothing," Paige says.

    The image stayed with her, and she resolved to do something to help. "I decided I would use my talents to throw birthday parties for homeless kids," Paige says. For the next four years, Paige and her husband, Colin, took time out from parenthood to visit shelters to determine how best to pull off the parties.

    Finally, in January 2017, Paige launched the Birthday Party Project, a nonprofit organization, and recruited friends and family to help decorate Dallas's 75- occupant Family Gateway Shelter with balloons and streamers, celebrating the birthdays of 11 boys and girls, with 60 more homeless kids in attendance. "That first party was better than I could have ever imagined," says Paige.

    Now Paige and her staff of three paid employees work with regional volunteers to plan monthly themed parties at 15 shelters across the country, some of which house abused or abandoned kids. Each child celebrating a birthday that month gets a $30 gift, a decorative place mat, and an individual cake or cupcake.

    One of Paige's favorite parts of each party is when the kids make a wish and blow out the candles. "They rarely get a chance to dream big," says Paige.

    Her daughter, Lizzie, now seven, often helps out at the parties. Paige says, "The one thing I've always wanted is for my kid to be generous."

    A video of a three-year-old girl being kicked by her own mother during a photo shot went viral (疯狂传播) on Thursday, indicating China's under per forma nee in regulating the emerging child modeling industry.

    The girl, known as Niu Niu, was physically abused by her mother in several videos. The videos have annoyed Chinese media and Internet users alike. Many netizens and scholars call for local authorities to carry out further investigations into possible child abuse.

    In response to the public outcry (强烈抗议), Niu Niu's mother issued an apology via Sina Wei bo on Thursday, condemning accusations of abuse. She noted that she was merely guiding her daughter for better shots and the girl is well looked after.

    Despite her apology, many E-shops which used Niu Niu's images for brand promotion have canceled their cooperation with the mother, while over 110 well-known child garment shops on Taobao have signed up for a campaign to provide better protection for child models.

    "It is necessary to adopt comprehensive laws and regulations to further protect the kids, preventing their parents and companies from exploiting (利用) them," Fang Zhiqing, a lawyer and child protection expert, said.

    Niu Niu is not alone. In Zhili, a small town in Zhejiang province, thousands of children from across China are taken here by their parents to seize the chance of fame. With a population of 450,000. Zhili has over 13,000 manufacturers of child clothing. In 2017, the town earned over 7 billion yuan by selling do thing for children online, thus providing opportunities for child models.

    "China's current advertisement law isn't workable when it comes to the industry of child modeling, as it lacks clear supervision measures and clear legal punishment." Fang added. "It is important to issue new laws which regulate child modeling."
