Powering up with a Catchy Tune

When watching sports events, we often notice athletes with their earphones on while preparing in the locker room or entering the stadium. They keep their eyes shut, and gently nod along the beats. It seems as if the music is empowering them and toughening （使更坚强）them up for the competition. We sometimes do the same. You might have a list of favorite songs for your morning exercises. But is there any science behind such practices?

According to a recent research, it turns out there is. Music actually does make us feel powerful, but not all songs have the same effect.

The research was led by Dennis Hsu of the Kellogg School of Management at Northwestern University in the US. His team had people listen to 31 songs of different types. The listeners felt powerful after listening to some songs, such as Queers We will Rock You and 2 Unlimited-Get Ready for This.

Researchers also found that high-power music made people want to take control in social events and come first in competition. That matters a lot in sports. " It's commonly said that sports are 90 percent mental and only 10 percent physical,” The HuffPost reported.

Great athletes know this idea well. Former NBA player Kobe Bryant, for example, often put on big headphones and even did a little meditation to boost his game and ease his anxiety.

As for the reason for music's magical power, Hsu's team came up with one possible explanation: when people hear music that expresses a sense of power, they mimic （模拟）these feelings in their mind.

When choosing music, we also need to look at the type of music, according to researchers.

In previous research by the Music in Exercise and Sport Group at Brunel University in London, they found that pop was perfect for slower, more repetitive-type tasks. If you're warming up or cooling down after exercises, pop songs are the correct choice.

Dance music was found to be best suited to strength and weight training because it's "fast and rhythmical （有节奏感的）".

During high-intensity （高强度的）workouts, though, you'd better not listen to rock. Its different changes in tempo （节拍）can affect your rhythm.

There are many things we need to know that we do not learn at school. For example, if we want to use our money wisely, we need to shop carefully...64. Knowing how to make such choices is "life skill", and we need it if we want to live useful and happy lives. Some of these choices are small. For example: Will I take an apple for lunch or a pear? Other choices are more important. For example: Will I work hard in all my classes or will I only work hard in the classes I enjoy? We make choices like this every day.

65. We have to realize that the choices we make can make a difference to the rest of our lives. Just as importantly, our choices can also affect (影响) other people. The next time you decide to waste time, play a joke on someone or talk loudly at the movies, think about this: Who else does your choice affect?

A special copyright (版权) case has recently drawn attention because it is related to (和….有关的) artificial intelligence (AI). A court (法庭) in Shenzhen ruled that a news report written by Tencent's AI enjoys copyright protection. 1.

This is the first case in China that has provided copyright protection to work done by AI. But what does it indicate (表明)? 2.

Probably not. AI is not yet able to write creative stories. The news report mentioned above is mainly about data. 3. Some newspapers also use AI to report on stories about natural disasters (灾害), which mainly require basic facts such as "where" and "when". As Forbes wrote, instead of losing their jobs, journalists can make their work more efficient (高效的) by using AI so that they can focus more on storytelling and less on numbers.

4. For example, Wayne MeGregor, a British choreographer (编舞), is famous for using AI to create new dances. For him, AI is a powerful tool that can help choreographers break out of common movements. MeGregor is not worried that AI might replace human artists. " 5."

"It's time to stop worrying about if AI can be creative," according to Forbes. Instead. we should focus on how humans and AI can work together in ways that we have never dreamed of before.

A.AI can't judge (判断) the quality (质量) of the choreography

B.AI is actually being helpful in many creative fields.

C.Will AI take the place of creative workers in the future?

E.Since AI is good at processing data, it is often used to write financial (金融的) reports.
