Have you ever eaten a “painting”? Here it is, the     1     (tradition) Chinese folk art—sugar painting. Spoon as pen, liquid sugar as ink, everything in the world can be drawn quickly.

As is said, Chen Zi’ang, a great poet in the seventh century (Tang Dynasty), liked to eat brown sugar. But he ate it in     2     unique way. He melted the sugar on a clean and smooth table,     3    (make) it into     4     (variety) of shapes of small animals. After cooling down, it could be held in the hand, eaten and enjoyed. Later, Chen went to the capital city,     5     he brought this art. Since then, sugar painting has become a lasting craft. In the 17th century (Qing Dynasty), sugar painting became     6     (increase) popular, and the production skills     7     (be) more advanced. The objects include flowers and birds, fortune symbols and the 12 zodiac signs and other designs. The art of sugar painting combines food, culture and handicraft. The painting is done in one go without any draft.

The sugar painting     8     (create) today shows greater creativity in forms — Cartoon sugar painting, 3D sugar painting, bringing new life     9     conventional ones. The culture of China, and the spirit of sugar painting,     10     (pass) down through the sugar spoons of generations of craftsmen.

3 . A team of scientists is studying the sound of the forest in Ecuador to learn how artificial intelligence (AI) could follow animal life in recovering environments.

When scientists want to measure new forest growth, they can study large areas of land with tools like satellites. But understanding how fast and in what number wildlife is returning to an area is more difficult. Sometimes it requires an expert to listen through sound recordings and pick out animal calls.

Jorg Muller, an expert on birds, wondered if there was a different way. So, he turned to bioacoustics (生物声学), which uses sound to learn more about animal life and their living environments. Muller and his team recorded wildlife sounds in Ecuador. They first had experts listen to the recordings and list the sounds of different animals. Then, they examined the sound quality to measure the environment. Finally, they ran two weeks of recordings through an AI computer program trained to understand 75 different bird calls.

The program was able to pick out the calls on which it was trained. However, scientists wondered if the program could correctly identify the number of different kinds of plants and animals in each environment. To see if the program could do that, the team used two different controls. One was from the experts who listened to the recordings, and the second was based on examples from each environment, which can be used to understand biodiversity (生物多样性).

Since the number of sounds that are found to be used to train is limited, the AI program could only identify one-fourth of the bird calls experts could. But it was still able to correctly measure biodiversity levels in each environment, the study said. It also said the results show the AI program is a powerful tool to measure the recovery of animal societies in some forests. The study showed that biodiversity found from recordings can be measured in a cost-effective and complete way and measure environments.

There are still areas for improvement, including the lack of animal sounds on which to train AI models. And the method can only catch animals that use sound to communicate.

4 . We are often told that there’s no _________ limit when it comes to pursuing our goals, but it’s truly _________ to see someone achieve them later in life-especially if they are 95 years old.

Angela Alvarez is a Cuban-born singer and songwriter who finally _________ her first album in 2021. Now, she has just won the Latin Grammy for Best New Artist.

Growing up surrounded by music, Alvarez once told her father she wanted to become a (an) _________ singer. However, life wasn’t easy for their family then and she had to _________ her dream of pursuing a career in entertainment for decades, but music was always there to keep her company and bring her _________.

With time, her kids had kids, and one of her grandchildren, Carlos Jose Alvarez, _________ found out that his grandma had _________ over 50 songs throughout her life, he knew that something had to be done. He asked her if she would be interested in going to a studio and _________ her songs. “And her answer was ‘Carlos, my dream is to __________ this life knowing that somehow my music would emerge and last.’ And that was the __________,” Carlos said in an interview.

Alvarez’s story __________ caught the attention of actor Andy Garcia, who decided to become the producer and narrator of Miss Angela, a documentary about this amazing woman. “Her story just blew me away. She __________ a generation, perhaps our generation of Cubans,” said the actor.

The dream reached new __________ as she became nominated (被提名) for a Latin Grammy. When she took to the stage to accept her award, she gave an inspiring speech, “To those who have not achieved their dream, I promise, with __________ and love you can achieve it, it’s never too late.”

5 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.

There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.

At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.

Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.

However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.
