1 . A wildlife photographer was waiting, hoping to get a shot of a relatively rare bird, a particular kind of heron(鹭). He’d waited several frustrating hours in the woods, but with no luck at all. Suddenly, to the photographer’s delight, a heron settled on a branch right in front of him. The photographer raised his camera and took the shot. Feeling particularly pleased, the photographer looked at the image. To his astonishment, he saw that behind the heron, his photograph had also captured a very, very rare woodpecker flying past. He hadn’t seen it, but without even trying, he’d photographed an even rarer bird than the one he was aiming for. This is an example of serendipity.

Cases of serendipity can be found in numerous fields, such as science. Back in the 1800s, a man called Wellswas at a demonstration (演示) of laughing gas. After being given the gas, the patient started laughing, as expected. But then he suddenly fell over and cut his le g rather badly. To everyone’s surprise, the man reported that he couldn’t feel any pain. Wells hadn’t been looking for it, but he’d made a medical discovery — certain gases reduce and can even almost eradicate pain. Had Wells not been there that night, anesthesia (麻醉) might have taken longer to be discovered.

Most of us can probably think of at least one example of serendipity in our own lives. Jane, a friend of mine,was trying to come up with an idea for an article but got completely stuck. Frustrated, she decided to go out to a local café. As she was sipping her coffee, she heard two people talking behind her. A man was telling a story that sounded so unbelievable that she knew it had to be true. She asked the people if she could interview them for the article. They agreed and her article turned out to be one of the top trending articles of the week.

2 . Everywhere I look, there are new buildings under construction. The neighborhoods that I knew as a boy, filled with beautiful old buildings, have mostly disappeared, and in their place, modern, high-rise buildings have appeared. There is good reason for this. Residents want all the conveniences of modern living. However, how can our children understand and maintain their cultural identity if we erase so much of the physical evidence of it?

The arguments for preserving historic buildings are not simply about an emotional attachment to the past. There are also good economic arguments in favour of preservation. The renovation (修缮) and preservation of historic districts can become an economic engine, drawing tourists and small businesses to the area. For example, in Dubai, the historic Al Bastikiya district draws thousands of tourists every year from all over the world. It also attracts local residents, eager to learn about their city's past.

Some have argued that historic preservation is too expensive, but many recent projects have demonstrated that this is not necessarily the case. In fact, renovation of an existing structure for adaptive reuse can cost about £40 per square metre less than even the most basic new construction, while preserving the beauty of the original building. And, although it is often claimed that old buildings have a more significant environmental footprint than new construction because they aren’t very energy efficient, architects and environmental experts maintain that the greenest building is the one that is already built. New construction almost always has a more serious environmental impact (影响) because it requires the use of all-new materials that must be transported, often over long distances, instead of recycled materials that are already on site. We recycle so many other things. We can and should recycle buildings, too.

Historic preservation is an option that opens many possibilities; demolition (拆毁), in contrast, is irreversible. Once these treasures are lost, they are lost forever, an important link in our heritage that can never be recovered.

6 . Our ancient nomadic(游牧的)ancestor would often sing or dance to show others where to find food. In my family, we’ve always had music around us too and this influence is starting to _______. Our seven-year-old son has _______ to perform his own raps which are quite excellent even without considering how _______ he is. Our four-year-old daughter is showing her musical _______ too — she started to make up little ditties(小调).

What is most joyous about our shared _______ of music are those moments when we all come together as a _______. My favorite time happened in April when I was feeling quite _______. I was cooking breakfast when the kids _______ that I was playing dance music. My seven-year-old son then started to join in dancing. This _______ his four-year-old sister, soon the three of us were jumping up and down. It was a moment of real ________ and it turned around how I was feeling.

At that point, I felt like music would be the way to ________ to the kids. I’ve sat down with my son and together we’ve remixed his voice and I’ve sat with my daughter and we’ve played the guitar. We might not be ________ anything about the whereabouts of food as our ancestor did. But we are giving them an ________ through song. We’ re teaching them “Flower of Scotland” so that they might know something about their heritage.

Through ________, we have all become a ________ family.

7 . One afternoon in 2022, something on the Internet caught my eye：a tiny hedgehog (刺猬) held by a big hand. The post read: “HELP! My hedgehog abandoned (抛弃) her two babies, and I cannot raise both of them because I have to go to school full­time. Good home with experience needed as soon as possible!”

I had no experience with baby hedgehogs. I was an animal person through and through and had raised cats, dogs, birds, and guinea pigs. But this tiny animal was new to me, and it touched me that he was abandoned, that maybe I could love him and be the best mom for him.

I wrote the most heartfelt email I could. That was how I found my Louie. True to my word, he was my baby. Louie didn’t know he was a hedgehog. He never curled (蜷缩) into a ball, and he liked my two cats, no fear. The cats, however, were afraid of him, as he often moved into the room, running after the cats and blocking my way.

By the time he reached old age, Louie had only three feet. However, he still managed to climb the stairs to visit other animals. He helped me realize my dream of hedgehog photography, a hobby that began during childhood with cats and dollhouses. I love showing off his modeling.

Life has meaning because of the purpose we have. Louie needed a good home and mom, and in return, I got to be a good mother and be needed. Hedgehogs require great amounts of patience, trust, and knowledge—but the payoff (回报) is pretty great.

9 . Kristin and her family have just moved to the community and were thinking hard to ________ with their new neighbors. One day, Kristin ________ a picnic table. _________, the delivery man sent one table with the wrong color ________ . Kristin couldn’t bear the ugly table, so she painted it turquoise—a color she ________ —and placed it in the front yard.

That table then became the place where Kristin and her kids ________ . Activities they used to do inside the house, they now did out at that ________ in the front yard. They played games, did crafts and ate snacks there. “We ________chose this place to spend our time,” Kristin says, “We became ‘front yard people’.”

Gradually, her ________ began to stop by to introduce themselves and sit down for a chat. Kristin also invited people to ________ her at the table for coffee or iced tea. Construction workers on jobs in the neighborhood took their lunch ________ at the table. A milkman riding by sat down to rest.

“It was a(n) ________ way to slow down and connect with others,” she says. The turquoise table was inviting and ________ a sense of community. Then neighbors ________ Kristin’s idea and they also put a picnic table in their own front yard. Now dozens of turquoise tables began to exist in the yards, ________ people from the community.

10 . Humans feed thousands of songs to AI (人工智能). And it is able to analyse the basic information and recognize patterns that can be used to create original music. Such AI-created music is similar to those that any musician might compose.

Recently, an AI-powered system, the Flow Machines, has released a song Daddy’s Car. This system is able to analyse the composers’ original ideas and come up with more ideas to assist them in composing. The system tries to combine the human mind with AI.

Another great invention is Jukedeck, which works very easily. In order to create a new piece, the user just needs to select items like the desired music style (folk, rock, etc.) and the mood (sad or happy). After a few seconds, AI provides a piece of music for the user to download. Each user can create music tailored to his or her interest.

Some musicians use AI to achieve what they could not do on their own. For example, Yacht, an American pop group, has used AI to break out of their comfort zone and try to create something different from their previous songs. Soon they have their new album, which contains 10 songs, all of which are very popular.

The development of AI technology also comes with some concerns. Some human composers fear that their work might be replaced by a machine. Some others are worried about music itself and the music industry, as AI is now able to create music more and more similar to human-composed music.

Faced with this challenge, on one hand, human musicians need to remain creative; on the other hand, they should understand how to use these new tools to explore new frontiers. Perhaps the future role of the human musicians will be to focus on emotions, leaving the machines to take care of other procedures.
