1 . Since the age of four, Jacquelyn Hill had dreamed of becoming a dancer. However, a car accident put the high school senior in the hospital for 5 days and left her paralyzed from the waist down and ________ to sitting in the wheelchair the whole life. For most people, that would have ________ any hope of a dancing career. For Hill, it was the beginning. ________ being a barrier, her wheelchair brought her bravery and encouraged her to think a lot of her life and she wanted to prove that she was still ________. Actually, Hill made it, rolling her wheelchair right alongside her non-disabled high school dance team. “It feels as if half of my body were ________ from me, and I have to move it with my hands,” Hill said. “ It ________ took a lot of learning and ________.”

After graduation, she wanted to expand her dancing network to include women like her. She began to ________ people online who had suffered similar injuries and shared her determination. Then in 2014, Hill moved to Los Angeles and formed a team of dancers with disabilities she calls the Rollettes. “I want to ________ the false belief of wheelchair users and show dance is dance, whether you’re walking or you’re ________.”

Dancing on wheels can be just as fast-paced, artful and ________ as the foot-based variety. In disabled dance competitions around the country, her team danced to the popular ________, rocking their ________ bodies, shaking their heads to the special beats, and ________ their wheelchairs in well-timed, dynamic, highly designed routines. The cheers, whistles and applause of the audience suggested that the fun was ________.

5 . Music has long been considered to be an enjoyable pastime for many people.     1    . The mental health benefits from music can’t be argued. Music could also be helping you with many other health problems behind the scenes.

Some experts say that music can be harmful if it is too loud. However, for the same reason, music can be very beneficial if one is in pain. By distracting the mind from the pain, music, people say, can lower stress and anxiety levels.     2    .

Many people enjoy relaxing music in the evening prior to going to bed.     3    . While the validity of the idea is still being assessed, the lowered stress can even be tied back to blood pressure. Similarly, according to researchers, listening to just 30 minutes of soft music every day may help with healthy blood sugar levels, through the lowering of stress and anxiety.

When it comes to heart health, there is speculation (推测) that it’s not the style of music, but rather the tempo (节奏) that makes it so good for your heart health. In one European study, participants listened to music as the researchers monitored their heart rates and blood pressure.     4    . On the other hand, when the music slowed, the participants’ stress and anxiety levels became lower and the effects on heart rates appeared to follow suit.

    5    , which is what makes music so valuable.

10 . Beethoven, one of the world’s most-loved composers, is famous for his nine symphonies. Before he died, he began a new symphony, but never finished it. Computer scientists and musicians have now used artificial intelligence to finish his 10th Symphony.

Beethoven wrote many famous pieces of music, but he’s probably best known for his nine symphonies. When Beethoven died in 1827, he had some ideas for a 10th Symphony. But all he left behind were some notes about the piece and a few “sketches” — short bits of written music.

In 2019, a special team of musicians, computer scientists and historians was formed. Their goal: to try to complete Beethoven’s 10th Symphony to celebrate his 250th birthday.

The team didn’t just want to complete the symphony. They wanted to come as close as possible to producing the symphony that Beethoven meant to write. That’s where deep learning came in.

To fulfill the task, the team trained an AI to help with the symphony. They turned every piece of music that Beethoven ever wrote into a form the computer could understand.

By feeding the program all of Beethoven’s music, the AI could look for patterns in the way Beethoven wrote. This included, for example, how he re-used simple melodies all through a piece to create a theme, or how he moved between different parts of the symphony.

Finally, the AI had the challenge of trying to connect the little musical bits into a symphony. It took over two years, but the team was able to complete Beethoven’s 10th Symphony. Not simply a melody, but40 minutes of music for a full orchestra.

So Beethoven now has a 10th Symphony. And though Beethoven didn’t write it all, we feel sure that the music is very much like what he might have written, if he’d had the chance.
