3 . What color of wearing do you like? Do you know “dopamine dressing (多巴胺穿搭)”? It’s one of the most talked about fashion trends (时尚趋势) for 2023. However, is there any science behind this?

“Dopamine dressing” came out from the book Dress Your Best Life. American fashion psychologist (心理学家), Dawnn Karen wrote this book in 2020. In the book, dopamine dressing is about wearing colorful clothing to get more dopamine.

Dopamine is a chemical in our brain. This kind of chemical makes people feel good. Our brain gives it out when we eat delicious food, play with our pets, listen to our favorite songs, after we exercise or when we win a game.

According to Science Focus Magazine, there are studies that show a relationship between the colors of the clothes we wear and how we act and feel. One study found that wearing red can bring better physical performance. It also showed bright colors can make people feel active. One more study showed that wearing green can help people relax because it is the color of nature. Yellow, the color of summer and warmth, can bring people happiness. But there are some problems with these studies, as people from different cultures have different ideas about dressing and colors.

In a word, “dopamine dressing” shows that we can wear colorful clothes to get more dopamine and feel good. Dressing is more than just a trend. It’s also a way of showing ourselves. So, next time you’re getting dressed, think about which colors will bring out your best self.

5 . Harbin, located in northeastern China, is known for its freezing cold winters and fantastic ice sculptures (雕塑). Over the years, the city has changed itself into a popular tourist destination (目的地), attracting visitors from all over the world to its Ice and Snow Festival.

According to He Jing, the director of the Heilongjiang Provincial Department of Culture and Tourism, Harbin’s popularity is not just a coincidence (巧合), but the result of a year of careful preparation. Since the beginning of 2023, the city has been developing plans to improve the tourism industry and attract attention from various social media platforms (平台). She said, “We put ourselves in the shoes of tourists. We pay special attention to the comments (评论) under social media platforms. Whatever the tourists complain about, we take action to improve at once.”

To “rescue” tourists who are not used to cold weather, Harbin has set up many heated places for them and provides free hot drinks. Local frozen pears are cut into flower shapes for tourists. The city even placed a large artificial (人工的) moon above the Saint Sophia Church for tourists to take photos. He Jing said, “We want to make visitors feel comfortable and respected.”

Touched by these “small details”, tourists share their heartwarming moments online, attracting more tourists to the city. This winter, Harbin received over 3 million tourists, generating 5.9 billion RMB. Hope more visitors will experience the city’s charm and warmth.

6 . Roger Federer, a world-famous sports star, quit (放弃) the 2020 Olympic Games to deal with his knee problem. It was a hard decision because no one wanted to be a quitter. But finding the courage to let go can be good for you.

Nothing is fun all the time. Never giving up doing something difficult teaches us important skills like perseverance. However, learning to let go when things aren’t right is important too. Maybe your heart isn’t in playing the piano any more, or you only play football because your friends do and you want to try a different sport instead. Making the decision to walk away can make you have more free time and energy to spend on something you really enjoy. In fact, studies show that not paying much attention to the goals you can’t reach or don’t really want can build up your confidence and help you lead a happier and healthier life.

But how can you know it’s time to stop or move on? Eric Bean is an expert in sports psychology (心理学) who helps athletes and teams understand their feelings. He says, “Quitting is never a matter of black and white.” He suggests thinking carefully about why you aren’t enjoying something any more. Is it because you’ve argued with a teammate or can’t get on with a new art teacher? Talk about this with an adult or a friend who you trust. That can help you decide whether you should stick or quit.

Quitting doesn’t completely mean giving up, though. For example, playing an instrument might be more fun if you want to take away the pressure of exams. If you decide to give up an activity, Bean suggests picking up another where you can still enjoy things like teamwork, creativity, and exercise.

When ChatGPT came out, Olivia Lipkin, a copywriter in San Francisco, found herself with less and less work to do. Last April, she was fired with no explanation. She realized the reason when hearing managers talking about how using ChatGPT was at a lower cost than having a human writer. Eric Fein had worked in a writing company for ten years. He became jobless last March because of ChatGPT. He said to his boss that ChatGPT couldn’t write with his level of creativity. His boss said he understood, but he would have to pay more to Fein than using ChatGPT.

AI systems like ChatGPT could replace (替代)hundreds of millions of jobs in the future. And for those who write social media posts and ads, the effect is already here. However, experts say that even the best AI systems can’t match the writing skills of a human. It doesn’t have a personal voice or style. Besides, it often gives the wrong answers.

Indeed, companies that have replaced human workers with ChatGPT have run into trouble. CNET, a technology news site, once used Al systems to write articles. The results, however, were full of mistakes. And the U.S. National Eating Disorders Company once replaced its helpline workers with robots. But it had to stop using the technology after the robots gave people harmful advice.

After being replaced by ChatGPT, Fein and Lipkin didn’t give up. Fein has decided to be an air-conditioning technician(技师), a job that AI can’t do. And Lipkin now works as a dog walker. She says, “People are looking for the cheapest solution, and that’s not a person-it’s a robot.”

9 . Have you ever heard of a famous charity called Operation Smile? We hope we can help you understand how we are trying to help children all over the world.

Operation Smile was started by a doctor and his wife. In 1982, together with some volunteers, they went to Philippines to help children who had holes in their lips or inside their mouths. It was very difficult for them to eat and drink. These volunteers worked very hard. But they worried that they could not carry on with the work because they were short of money. Then they decided to start a charity so that they could help these needy children. They called it Operation Smile.

Operation Smile works in more than twenty developing countries and has cured over 300,000 children who have problems with their mouths. Operation Smile has won many prizes for its work and in 1999 they even started a special event called “The Journey of Hope”. 5,000 children in 18 countries were cured during the event.

On the other hand, Operation Smile trains local doctors and nurses in developing countries so that they can continue to help children when Operation Smile has left. As to the children with much more serious problems, they will send them to the USA for further treatment.

So show your kindness to the needy children now. You can send your donation to Operation Smile at local banks. Many thanks from the children who can smile now will come to you.

10 . People think children should play sports. Sports are fun, and children stay healthy while playing with others. However, playing sports can have negative influence on children. It may produce feelings of poor self-pride or aggressive (攻击性的) behavior in some children. According to research on kids and sports, 40 million kids play sports in the US. Of these, 18 million say they have been shouted at or called names while playing sports. This leaves many children with a bad impression of sports.

Many researchers believe adults, especially parents and coaches, are the main cause of too much aggression in children’s sports. They believe children copy aggressive adult behavior. Parents and coaches are powerful teachers because children usually look up to them. Often these adults behave aggressively themselves, sending children the message that winning is everything. At children’s sporting events, parents may shout at other players or cheer when their child behaves aggressively. As well, children may be taught that hurting other players is acceptable, or they may be pushed to continue playing even when they are injured. Children watch adult sports games and see violent behavior replayed over and over on television.

As a society, we really need to face up to this problem and find out the causes behind them. Parents and coaches should act as better examples for children. They also need to teach children better values. They should teach children to enjoy themselves whether they win or not. Winning is not everything. In addition, children should not be allowed to continue to play when they are injured. Sending a child with an injury into a game gives the child the message that health is not as important as winning. If we make some basic changes, children might learn to enjoy sports again.
