1 . The first way we learn to communicate is through body language — our facial expressions, our gestures and, when we’re older, our postures. Even after we figure out how to speak, this non-verbal communication still exerts (施加) a powerful and often unconscious influence over our interactions, people’s first impressions of us and even our impressions of ourselves.     1    .

Change how you feel

To de-stress: Forcing a smile can make running easier and tough tasks less stressful. One 2012 experiment found that a grin makes holding your hand in ice water more bearable.

To feel more confident:     2    . Striking this so-called power pose shortly before an interview or athletic contest can be particularly powerful for women, who tend to sit and stand in a way that takes up less space.

To persevere:     3    . In a 2008 study, students who sat with their arms crossed kept working on an impossible problem nearly twice as long as those with their arms at their sides.

Change how others feel

    4    : Studies show that holding someone’s gaze may help people think you’re trustworthy and intelligent. According to body language expert Carol Kinsey Goman, it can also make people think you’re a good listener.

To foster connections: Mirroring the facial expressions and gestures of the person you’re talking to can help them feel more comfortable. One 2011 experiment found this is an effective sales skill.

To engage or disengage: If you want to let someone know you’re listening, sit facing them with your full body, knees and shoulders pointed at them.     5    .

2 . British humour has deep roots dating back to medieval times when jesters entertained royal courts with their witty antics. Over the centuries, it evolved from slapstick comedy to the satirical genius of writers like Jonathan Swift and Oscar Wilde. The British love for wordplay and absurdity found its voice in the works of Lewis Carroll and Edward Lear.

British humour is as diverse as a pub menu, but certain characteristics underpin its charm. The British have a habit for self-mockery, and the ability to laugh at oneself is a hallmark of British wit. Sarcasm and irony are close friends, and understatement often delivers the funniest punchlines.

Puns, wordplay and the absurd are common tools in the humour arsenal. Whether it's making fun at the weather or revelling in the delights of innuendo, English humour is all about embracing the sudden twists and oddities of life.

English humour boasts a rich tradition of comedic brilliance, and one of its shining stars is PG Wodehouse. Within the literary realm, Wodehouse’s work, particularly the misadventures of Bertie Wooster and his unflappable valet Jeeves, showcases a brand of humour that has delighted readers for generations.

Visiting Britain? Prepare to be pleasantly confused. English humour can be disarming, especially if you are not used to the art of sarcasm and the subtlety of understatement. But it is all in good fun. Engage in friendly conversations with locals, try your hand at some humour and don't be afraid to enjoy a healthy dose of irony. You might just find yourself laughing over a pint with newfound friends.

4 . The human eye can perceive about 1 million colors, but languages have far fewer words to describe those colors. Languages spoken in industrialized nations such as the United States, for example, tend to have about a dozen basic color terms, while languages spoken by populations in remote areas often have fewer. However, the way that a language divides up color space can be influenced by contact with other languages, according to a new study.

Among members of the Tsimane society, who live in a remote part of the Bolivian Amazon rainforest, the researchers found that those who had learned Spanish as a second language began to classify colors into more words, making color distinctions that are not commonly used by Tsimane who are monolingual (单语的).

In the most striking finding, Tsimane who were bilingual (会双语的) began using two different words to describe blue and green, which monolingual Tsimane speakers do not typically do. The researchers also found that the bilingual Tsimane became more precise in describing colors such as yellow and red, which monolingual speakers tend to use to include many shades (色度) beyond what a Spanish or English speaker would include.

Working with monolingual and bilingual members of the Tsimane, the researchers asked people to perform two different tasks. For the bilingual population, they asked them to do the tasks twice, once in Tsimane and once in Spanish.

In the first task, the researchers showed the subjects 84 chips (块) of different colors, one by one, and asked them what word they would use to describe the color. In the second task, the subjects were shown the entire set of chips and asked to group the chips by color words.

The researchers found that when performing this task in Spanish, the bilingual Tsimane classified colors into the traditional color words of the Spanish language. Additionally, the bilingual speakers were much more precise about naming colors when they performed the task in their native language.

“The bilingual speakers learned a different way to divide up the color space,” says Edward Gibson, the senior author of the study. “It’s a great example of one of the main benefits of learning a second language. You open a different world and understand different concepts that you import to your native language.”

5 . Every morning on the island of Oahu, students at Pu’ öhala Elementary gather on a field as towering mountains watch them from the mist. Their day starts with songs in ‘ölelo Hawai’i, the islands’ native language, restating values of respect and justice that their teachers hope will guide them through their education, and throughout their lives.

Like most kids their age, they’re not concerned about the significance of the language they’re learning. Still, they have a weighty responsibility: to receive the torch (火炬) and ensure the security of ‘ölelo Hawai’ i for future generations.

It was only 50 years ago that the language was on the edge of extinction. Though the situation is much improved, in many ways ‘ölelo Hawai’ i is still on life support. Teachers say there’s a huge enthusiasm for school kids to learn the language, but as they grow up, they’re encouraged to focus on “more useful” subjects and use English, which are believed to assist them in achieving success in their work. In 2016, there were 18, 610 Hawaiian speakers on the islands.

“One hundred thousand is the approximate number of speakers needed to consider the language safe, ” says Solomon, professor of Hawaiian language at University of Hawai’i at Manoa. “The idea is that there are enough people passing it on to the next generation, socializing their children to use the language in all domains of life, to express all thoughts and needs and desires. ”

Fortunately, the kids of Pu’ öhala Elementary will take the responsibility to continue the work of the current young adults defending the language, expanding access to ‘ölelo Hawai’i in part through TikTok and Instagram, and making the language a practical skill in adulthood. These youth, along with those committed to recovering the language from previous generations, share their hopes for the better.
