It's a classroom. Instead of being told to sit quietly and listen, you are encouraged to stand up, jump around, imagine and act out. It's a class full of laughter and applause (鼓掌), emotion and energy. Welcome to drama class, one of my favorite classes at high school.

    In drama class we used to play a lot of “drama games”. We would improvise (即兴表演), copy and above all use our imagination.

    My favorite game was called “Spotto”. One person stood in the front of the class and performed a scene, completely out of their imagination. When one audience member yelled “Spotto!”, the performer had to freeze. Then the person who had yelled Spotto had to get up and improvise a new scenario (剧情) based on the position the first performer froze in. This went on as more and more people were added to the scene. Eventually the entire class would have joined the scene. Then the performers would start to leave in reverse (颠倒的) order.

    It was a lot of fun, and a good test of everyone's imagination to see what they would come up with. Drama class at my school often involved a big performance at the end of the term as well. We would work on a production throughout the term and put on a show for our parents and the school community.

    It was a great experience to perform on stage in front of a large audience. Drama class can help shy children, like me, to come out of their shells. It helped them become more confident and developed their public speaking skills. Drama class is also a great place to express oneself, and a way for children to use up some of their energy.

    If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

    According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.

    The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.

    Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.

    "Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.

    It means that the change itself increases the ability to learn.

    Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的)," he said. "You are actually going beyond language and have a better understanding of different ideas."

    The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.

    Recently a movement was launched by Charity Cycling UK to raise awareness of dooring after discovering that many people don't know what it is. Dooring is when a driver or passenger opens the door into another road user—typically a cyclist—without looking for other road users.

    Cycling UK Chief Executive Paul Tuohy told Gloucestershire Live: "Some people seem to see car dooring as a bit of a joke, but it's not and can have serious consequences. Cycling UK wants to see great awareness made about the dangers of opening your car door carelessly，and people to be encouraged to look before they open."

    The charity says 2,009 of the 3,000 injuries happened to cyclists, resulting in five deaths but says this might not be the full extent of the danger.

    Cycling UK says not all car dooring incidents will be attended by police, so the charity has written to transport minister Jesse Norman calling for a public awareness campaign urging all car occupants, not just drivers, to look before opening vehicle doors. One of the ways the charity suggests is the "Dutch reach", where people leaving a vehicle reach over and use the non-door side hand to open the door.

    Cycling UK also suggests harsher laws and advice on safer road positioning for people who cycle.

    Mr Tuohy said: "In the Netherlands they are known for practising a method，known sometimes as the 'Dutch reach', which we think could be successfully encouraged in the UK."

    "Cycling UK has written to the Department for Transport asking them to look into this, and highlight the dangers of "car dooring" through a public awareness THINK style campaign."

    If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what's known as the "Dutch reach" to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside the car.

The Tokyo Olympics have been postponed until 2021. That delay offers a chance for reflection. The International Olympic Committee wants to make the games more popular with young people. To that end, it is introducing new events, such as skateboarding, surfing and climbing. Why not go further and let national teams compete at video games? Electronic sports such as "Fortnite", are vastly more popular than strange Olympic sports like curling (冰壶). In fact, they are more appealing than most mainstream sports. Only 28% of British boys aged 16-19 watch any traditional live sports; 57% play video games.

Some may complain that e-sports are not proper sports. Many parents, observing their teenagers sitting on the sofa all day shouting "Quick, pass me the shotgun!" at a screen, would agree. Yet video games are highly competitive, with professional teams that play to packed stadiums. There are perhaps only 200 tennis stars in the world who can make a living from playing in major competitions. By contrast, "League of Legends", a fantasy game played by teams of five, supports over 1,000 on good wages. Its World Championship final last year was watched by 44 million people.

Those against e-sports offer moral objections, too. They are addictive. Prince Harry has called for "Fortnite" to be banned for this reason. They are violent. At a time of global disharmony, it is bad idea to make virtual (虚拟的) killing an Olympic sport. The Olympics aim to promote peace.

Neither of these arguments is convincing. The idea that an activity, rather than material, can be addictive is controversial among doctors, as is the existence of a causal (因果的) link between gaming and violence. And the belief that warlike sports have no place in the Olympics is hard to agree with history. Wrestling was introduced in 708 BC. It is still there.

The American Psychological Association（APA） has issued its first advisory on social media use in adolescence（青春期）. What's most striking in its data based on recommendations is how little we really know about how these apps affect our kids.

The relative newness of platforms like Snapchat and Tik Tok means little research is available about their long-term effects on teen and tween brains. Getting better data will require significant funding—and much more openness from tech companies.

"What little evidence we do have unsurprisingly suggests that social media trades on motivators that aren't great for young brains. Many kids' first exposure to social media occurs at the worst possible time when it comes to brain development," says Mitch Prinstein, a psychologist and neuroscientist at the University of North Carolina（UNC）.

"Things like 'button and artificial intelligence（in general）' are going to affect young people's brains in a way that's very different from adult brains when it comes to the desire to stay online and to say or do almost anything to get followers." When it comes to social interactions, he compares kids' brains to a car with a huge gas pedal and weak brakes（刹车）.

Earlier this year, Prinstein and his UNC colleagues published the results of one of the first studies of how the adolescent brain reacts to social media. The team surveyed a group of middle schoolers to understand their social media habits, and then stuck them in an MRI machine to watch their brains as they reacted to social rewards or punishments. They found that 12-year-olds who habitually checked social media had distinct neural patterns, with more activities over time in parts of the brain associated with motivation, salience（or where attention is focused） and cognitive control.

The team didn't weigh in on whether those differences were good or bad, or whether the relationship was causal or correlational. But their work points to the need for more research. It should also remind parents of the need to be keenly aware of social media's hidden influence on still-developing brains.
