Traditionally, across the world, boys and girls attend a mixed school, where they study together. But boys' schools are the perfect place to teach young men to express their emotions (情感) and encourage them to take part in activities such as art, dance and music.

    Boys at single-sex schools were said to be more likely to take part in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to correspond to(和…相符) the "boy code" of hiding their emotions to be a "real man".

    The findings of the study go against accepted wisdom that boys do better when taught together with girls.

    Tony Little, head master of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.

    The research argued that boys often perform badly in mixed schools because they become discouraged when girls do better earlier in speaking and reading skills.

    But in single-sex schools teachers can tailor (量身定做) lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.

    Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have more acute vision, learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around. "Boys in mixed schools view classical music as feminine（女性的） and prefer the modern genre （类型） in which violence and sexism are major themes," James wrote.

    Single-sex education also made it less likely that boys would feel that they had to be "masterful and in charge" in relationships. "In mixed schools, boys feel forced to act like men before they understand themselves well enough to know what that means," the study reported.

    It's OK to say you've never heard of grime (伦敦地下音乐) - unless you're from the UK. That's because this music type was invented in the UK in the early 2000s.

    To someone who's not familiar with underground music culture, it's easy to get confused between hip-hop and grime since they are both noisy. And many people didn't bother to tell them apart，until earlier this month when grime stars like Stormzy and J Hus led this year's Mobo – “music of black origin”, an award in the UK. Just like UK electronic music and hip-hop, from which grime drew influence, it mostly reflects the thoughts of young people. But different from hip-hop, grime singers sing in dialects with strong accents, giving a special flavor to their songs.

    Lady Leshurr，known as the “Grime Queen”, said that she once tried to hide her accent, as she didn't want people to judge her. But one day, she realized that she didn't need to change herself just to please others. And there's no doubt that this is the soul of grime music: be yourself.

    Grime has challenged modem music in its production beauty and its expressions. Also different from the hip-hop culture, which usually focuses on being rich, grime singers pay more attention to social phenomena like those who suffer from disasters and the gap between the rich and poor.

    Although still quite a young music type, grime seems to be getting loved by more and more people. In 2016, the English grime artist Skepta won the Mercury Prize with his album Konnichiwa, beating big names like David Bowie and Radiohead.

    However, no matter whether grime is one day accepted widely or not, one thing is for sure: in grime, singers always stay true to themselves.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

    "Are you going to Seattle?" an anxious-looking woman asked a female traveler at the Amtrak Airport in Sacramento. "No, I'm going to Eugene," the traveler replied. "Oh, I was hoping you could watch out for my daughter, she's never been on a plane before."

    Now, as I am quite a seasoned plane traveler, I know that seats and cars are supplied by destination（目的地）. So I came up to the woman and her frightened-looking daughter, telling them that her daughter could sit with me and that I would take care of her during the journey.

    The plane had arrived 25 minutes late, and people walked in line to get their seats. The conductor wanted to know if there were people traveling together, so I went to the front of the line with the girl and we were arranged to sit next to each other. Once on board, I showed her where to put her package, and took her to the bathroom area. Then we settled down to sleep. In the morning, I showed her the dining room and bought her a drink. She became comfortable enough to do what most 15-year-olds do: talk and text on her mobile phone.

    All through the trip, I made sure she picked up her ID, which had fallen out of her backpack, some money, which had fallen into the crack （缝隙） of the reclining seat, and continuously kept an eye on her. I hope someone takes her under their wing when she flies back to Sacramento.

    I do hope that kindness will spread around the world through these ways. We're conditioned to think that our lives go on with great moments. But great moments often catch us unaware, beautifully wrapped（包裹）in what others may consider a small one.

    Breakdancing is set to make its debut(首次亮相) as an Olympic sport at Paris2024, Tony Estanguet, head of the Paris organizing committee, said on February 21". Skateboarding, sport climbing and surfing which have already been added to the 2020 Tokyo Olympics, have been invited to return in Paris.

    Estanguet said the choices responded to a need to make the Olympics "more urban" and “more artistic". "We have chosen to present the International Olympic Committee (IOC) with the four sports because they are creative, appealing to youth and completely in line with our vision. They reflect perfectly Paris 2024's identity.”

    Breakdancing is an example of a sport "which can be played anywhere and anytime in urban and other environments." It appeared at the 2018 Youth Olympics in Buenos Aires in the form of head-to-head "battles". In competitive breakdancing, "breakers face off in "battles" against each other, either as individuals or teams. Breakdancers use- a mix of physical and artistic skills combining elements from gymnastics or acrobatics(杂技).

    The IOC had announced that the number of competitors at Paris 2024 would be restricted to 10,500, which limited the opportunity to add sports. But the organizers said the inclusion would not necessitate the construction of permanent facilities and would involve just 248 competitors, including 32 breakdancers. The surfing events are likely to be held in established surf center such as Biarritz or Lacanau in southwest France.

    The inclusion still needs to be rubberstamped by the IOC, which is expected to decide on which sports to add in Paris after next year's Tokyo Games.

    There is no point destroying your peace of mind and happiness by taking the wrong job. Society may pressure you into grabbing whatever you can get. If you do not have a set path that must be taken, then you have the opportunity to choose something you will not only be paid for doing, but enjoy.

    One of the best ways of finding a suitable career is to determine your personality type. It may seem obvious that the creative type does not really find much pleasure in a job as a butcher or dry cleaning assistant, and that a weak character may not find happiness in a career based on teaching or leading a team.

    To find the best job for your personality type, the first step is to know what and who you really are. If you already know your style, you can search for suitable employment; however, if you are uncertain, there are ways that will help you discover who and what you are. For example, an employment centre, a career adviser, or an online quiz can help you.

    Taking my own situation for example, I am definitely a creative type. Besides, I prefer to be my own boss or, if I cannot, at least I want to rely on a boss I truly both respect and admire. I do not like telling people what to do, or being told what to do. I do not relate well to regular 9-5 hours. I do not feel satisfied being paid a high wage for a bad job. I feel much happier at home. Combining my creativity, independence, and desire to stay at home, my ideal career would be running a home-operated business involving creativity. I actually happen to have chosen this solution; I am a writer, poet, author and publisher. I have suited my career to my personality type.
