1 . Beethoven was born over 250 years ago, yet his music is still played daily around the world. Beethoven wrote many famous pieces of music, but he’s probably best known for his nine symphonies (交响曲). Before Beethoven died in 1827, he began a 10th Symphony, but never finished. What he left behind were some notes about the piece and a few “sketches” (草图) — 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 wanted to come as close as possible to producing the symphony that Beethoven meant to write.
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 the way Beethoven wrote. Other members of the team studied Beethoven’s notes and sketches, and attempted to find out what Beethoven was planning to do.
One early test told the team they were on the right track. They took a few minutes of music created by the AI based on Beethoven’s sketches, and played it for Beethoven experts, musicians, and reporters. No one could tell which parts had been written by Beethoven and which parts the AI made up. Finally, the AI connected the little musical bits into a symphony. It took the team over two years to complete Beethoven’s 10th Symphony-40 minutes’ music.
So Beethoven now has a 10th Symphony. And though Beethoven didn’t write it all, the team feels sure that the music is very much like what he might have written, if he’d had the chance.

3 . Accidents happen almost daily. Some accidents are minor and some are serious but others may be fatal. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents occur only on the roads or highways, or even at worksites. Home accidents are just as common. Because very few home accidents are reported, people tend to think that there are few accidents which happen in homes.
There have been many cases where people fall to their deaths from high-rise flats. Children often fall from staircases while coming down the stairs. Old people may slip on wet or slippery floors if they are not careful.
Nowadays there are a lot of modern electrical appliances such as rice-cookers, electric irons, and kettles which make life easy for the modern housewives. These appliances can kill if they are not used in the proper way.
Gas stoves used for cooking are also dangerous if they are not properly handled. They may cause burns or, in more serious cases, they may even cause fires.
But all such accidents can be prevented if we are careful and obey simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how. It is safer for them to get their faulty appliances repaired by a qualified electrician.

If you are visiting with a child, take a moment to explain the ride to them, and tell them what they should do．They are depending upon you to keep them safe．Set a good example for them by following the rules of the park, and make sure that they know you expect them to follow those rules, too.
Tell them to stay seated, to hold the grab bar or put their hands in the laps, and not to stick their knees and feet outside a ride vehicle．Make them look to you for the okay to get on or off a ride, too．And never put a crying child on a ride．If your child starts to cry, let others pass you in line until your child is calmed．Or, gently exit the queue and find something more relaxing to do．
Young kids can’t keep an adult’s pace in a theme park．Let them take plenty of breaks.
“Kids get tired,” said TPI reader Matt Johnson, a father of four．“Tired kids make parents even more tired．And tired kids and parents may get hurt — physically and emotionally.” He advises that parents plan a mid-day break, perhaps a swim back at the hotel, to avoid mid-day heat and crowds．“You will see cranky families having a miserable time while you are refreshed and having a great evening.”
