We've all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

    What's the problem? It's possible that we all have compromised conversational intelligence. It's more likely that none of us start a conversation because it's awkward and challenging, or we think it's annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it's an invaluable social practice that results in big benefits.

    Dismissing small talk as unimportant is easy, but we can't forget that deep relationships wouldn't even exist if it weren't for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. "Almost every great love story and each big business deal begins with small talk," he explains. "The key to successful small talk is learning how to connect with others, not just communicate with them."

    In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. "It's not that talking to the waiter is better than talking to your husband," says Dunn. "But interactions with peripheral(边缘的) members of our social network matter for our well-being also."

    Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. "Small talk is the basis of good manners," he says.

    Have you ever been to Taiwan, China's biggest island? Do you want to pay a visit there? We'll show you the best of Taiwan is land.

    At the age of seven, while his friends were spending their allowances on candy and toys, Jose Adolfo Quisocola, from Peru, came up with the creative idea of an eco-bank, which allows kids of all ages to become economically independent and financially wise while also helping the environment.

    Established in 2012, The Bartselana Student Bank is the world's first cooperative bank for kids. Whoever wants to join has to bring in at least 5 kilograms(11 pounds) of solid waste(paper or plastic) and establish a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram(2.2 pounds) of recyclables on a monthly basis and obey other requirements, such as attending financial education and environmental management workshops. The waste accumulated is sold to local recycling companies, who, thanks to some clever negotiation by Jose, pay a higher-than-market rate for everything brought in by Bartselana Student Bank members. The funds received are placed in the individual's account where they collect until his／her savings goal is reached. The account holder can then withdraw his／her money, or choose to leave it and continue to grow for a bigger target.

    “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project, ” Jose recalls. “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school principal and an assistant in my classroom.”

    The youngster's persistence paid off. Today, the eco-bank, which now has the support of several local institutions, has ten educational centers and begins accepting applications from kids all across Peru. On November 20, 2018, the young boy was awarded the famous Children's Climate Prize (CCP). “Jose's eco-bank is a brilliant way of linking economy and climate impact, both in thought and practice. The potential impact is amazing,” a judge said.

    Hopefully, Jose's success will inspire more kids and adults to come up with new ideas that create value while helping the environment. As the boy says,” Together we can change the world…we just need an opportunity…”

    Imagine this: You're at the movies seeing the latest box-office hit. The leading actor chases down the film's bad guy before winning over the beautiful leading lady. What does he do next? He sucks on a cigarette.

    What's wrong with this picture? Doesn't the beautiful woman see her hero's yellow teeth? Doesn't she smell his smoky breath? And wouldn't the good guy have trouble chasing, since smoking causes a person to cough?

    But you don't see any of that when someone smokes cigarettes in the movies. And there is a lot of smoking in movies. Actors light up in more than 50 percent of youth-rated (G, PG, PG-13) movies, according to the American Legacy Foundation, which aims to put an end to smoking among young people. That means that Hollywood is showing 14 billion images of smoking to young people every year.

    All that exposure to on-screen smoking can influence teens to smoke. The Center for Disease Control and Prevention (CDC) argues that 44 percent of teens who begin smoking do so because they've seen smoking in movies. The CDC reports that teens are two to three times more likely to start smoking after seeing repeated smoking scenes in movies than teens who are lightly exposed to smoking in movies.

    Several organizations are working to remove smoking in youth-rated movies. And adults are not the only ones who care about this issue. Many teens are actively involved. Livia Clandorf, 16, of Chatham, New York, is a member of Reality Check, an organization that educates teens about what it considers to be the manipulative(巧妙处理的) practices of tobacco companies. Livia participated in an event called a "movie stomp(跺脚)". Reality Check rents out a movie theater and screens a youth-rated film that shows smoking, they stomp their feet and show disapproval by shouting “boo”.

    Polish President Andrzej Duda has signed a bill into law that largely limits trade on Sundays, saying it will benefit family life.

    The legislation（立法）, worked out by the government and the Polish trade union, is expected to draw protests from large western supermarket chains that are the main target of the law. A large part of their profit is earned on weekends.

    As of March 1, shops and markets are closed on two Sundays per month; in 2019 only one Sunday a month will be open for shopping; and starting in 2020, there will be no Sunday shopping with a few exceptions.

    Duda praised the law as giving children a chance to be with parents and giving shop workers some needed time off. He also said big traders will need to adjust their practices to the new system and asked them for "understanding". But critics say some of them make employees work long hours for modest pay.

    "A family should be together on Sundays," Olszewska said after buying some food at a local Biedronka, a large discount supermarket chain. She said that before she retired she served cold cuts in a grocery store, and was grateful she never had to work on Sundays.

    There are some exceptions to the ban. For instance, gas stations, cafes, pharmacies and some other businesses are allowed to keep operating on Sundays.

    Anyone breaking the new rules faces a fine of up to 100,000 zlotys （$ 29,500）, while repeat offenders may face a prison sentence. Polish trade union appealed to people to report any violators to the National Labor Inspectorate, a state body.

    While many Chinese watched movies at cinemas during the weeklong Spring Festival holiday, Zheng Wei explained the film The Spring Festival to an audience of visually impaired(受损伤的) people at cinema in Northern China's Tianjin.

    "Fireworks light up the dark on New Year's Eve, and children are playing in an open place covered with white snow, said Zheng to the audience, describing the visual elements of the movie while holding a micro-phone and a script.

    As the founder of "cinema for the blind" in Tianjin, the 55-year--old has insisted on brightening the dark world of the visually impaired in his own way for 11 years.

    Shao Yuxiang and her husband, who are both blind, are regular visitors of the cinema. She wore an elegant yellow sweater to attend the couple's significant "movie day".

    Since October 2007, the free movies, which are described through audio, start at 9: 30 am on the third Saturday of each month. More than 150 movies have been screened to more than 20,000 visually impaired.

    "The theater is equipped with lights a sound system, projector, and a big screen to give the blind a people so far complete and equal movie experience," Zheng said.

    In 2007, after having learned that a "cinema for the blind" established by Wang Weili had benefited many visually impaired people in Beijing, Zheng rushed to Wang's establishment for advice. Under Wang's guidance, Zheng built a new cinema in Tianjin and screened The Dream Factory by Chinese director Feng Xi-aogang. It attracted more than 50 visually impaired people from different districts and even suburban areas in Tianjin.

    Zheng always treats movie selections with seriousness He usually chooses Mandarin language movies with positive themes that reflect modern society. Special movies for certain Chinese festivals are also part of Zheng's selection criteria. "For example, The Founding of Republic is specially for National Day. Now, films for Spring Festival are on my agenda," Zheng said.
