21、“ Humans and machine algorithms (算法) have complementary (互补的) strengths and weaknesses. Each uses different sources of information and strategies to make predictions and decisions, ” said Mark Steyvers, UCI professor of cognitive sciences. “ We show through experiments that humans can improve the predictions of AI even when human accuracy is below that of the AI, and vice versa (反之亦然). This accuracy is higher than combining predictions from two individuals or two AI algorithms. ”
To test the framework, researchers conducted an image classification experiment where human participants and computer algorithms worked separately to correctly identify disorderly pictures of animals and everyday items including chairs, bottles, bicycles and trucks. The human participants ranked their confidence in the accuracy of each image identification as low, medium or high, while the machine classifier generated a continuous score. The results showed large differences in confidence between humans and AI algorithms across images.
“ Human participants were confident that a particular picture contained a chair, for example, while the AI algorithm was confused about the image, ” said Padhraic Smyth, UCI Chancellor’s Professor of computer science. “ Similarly, the AI algorithm was able to confidently provide a label for the object shown, while human participants were unsure if the disorderly picture contained any recognizable object. ”
When predictions and confidence scores from both were combined using the researchers’ new Bayesian framework, the mixed model led to better performance than either human or machine predictions achieved alone.
“ While the past research has demonstrated the benefits of combining machine predictions or combining human predictions, this work shows a new direction in demonstrating the potential of combining human and machine predictions, pointing to new and improved approaches to human-AI cooperation, ” Smyth said.
“ The blend of cognitive science focusing on understanding how humans think and behave and computer science in which technologies are produced will provide further insight into how humans and machines can cooperate to build more accurate artificially intelligent systems, ” the researchers said.

22、 The world famous Boston Symphony Orchestra normally performs at Symphony Hall in Boston, Massachusetts. But its summer home is the Tanglewood Music Center in western Massachusetts.
The Boston Symphony Orchestra also has a summer program at Tanglewood. It is designed for young singers, musicians and those who create musical works. Great composers like Aaron Copland, Leonard Bernstein and John Adams have worked There.
Serge Koussevitzky led the Boston Symphony Orchestra in 1940. At the time Europe was at war. The United States did not enter World War I until the end of 1941. Mr. Koussevitzky persuaded people in the music industry to open a music school at Tanglewood, the BSO’s summer home. He wanted young, gifted musicians toattend the school for free.
But within two years, the program almost came to an end. “The BSO trustees(托管人) wanted to close the school because of the war and Koussevitzky was angry, and wrote a letter calling it an ‘act of artistic vandalism(损坏)’. And he said, ‘Now is the time when the world needs to be hearing this music’,” says Jeremy Eichler, a music critic for The Boston Globe newspaper. “This music” was not Just works by Beethoven or Brahms. It was the sounds of the time.
Mr. Koussevitzky chose composer Aaron Copland to head the school. “In establishing Aaron Copland as the head of the school not as the head of composition, he was making a very specific statement…And I think he felt very strongly that paying attention to the music of one’s own time is the way to ensure that there will be a future,” says Jeremy Eichler.
Paul Hindemith was a refugee (难民) from the war in Europe. He was chosen as the first head of Tanglewood’s music composition department. He and Copland decided that the school would be a place where composers write new musical works.
Their first performance was Alleluia, a piece written by American composer Randall Thompson. Alleluia has opened the school’s program every summer since it was first performed. Since it opened, Tanglewood’s young musicians, singers and conductors have performed many new compositions. They include the first American performance of Benjamin Britten’s opera Peter Grimes. This year, for its 75th anniversary, the center asks composers to write 34 new pieces of music.

23、Many farmers in China are exploring new career paths. From drone (无人机) operators to social media influencers, new types of occupations taken on by Chinese farmers not only bring higher incomes but also put new life into China's rural area.
In April 2016, Yu Xiaojun, 28, founded an agricultural machinery services cooperative in partnership with his friends to provide services including sowing, crop protection and harvesting for large farms with drones.
The cooperative now has over 100 sets of machinery and equipment and more than 20 staff members. Many young people ask Yu to teach them how to fly drones.
As a short-video craze sweeps China, many farmers are becoming enthusiastic about sharing their lives online. Livestreaming has become a new farming tool, allowing farmers to reap the benefits of selling goods directly to urban consumers.
Holding a plate of dried sweet potatoes, Zhang Chuanfeng stood in front of a mobile phone to introduce the local products. The 40-year-old farmer is 1.4 meters tall and was worried about his future after struggling in various jobs because he is too short. However, his transition has been a success.
With the support of the local government, Zhang rented a stall and opened his online business. To improve his marketing skills, he attended training courses and learned from other online streamers.
In April 2020, Zhang started livestreaming sales. The products received positive feedback from the market, and that encouraged Zhang to include more types of local specialties in his sales.
His hard work paid off. Now Zhang has over 90,000 followers on the Douyin short-video platform. He made 5 million yuan from sales of local specialties last year. He also volunteered to help locals sell other products including honey, organic eggs and fish through livestreaming.
“Through my efforts, I have lifted my family out of poverty, which was unimaginable before,” Zhang said. “Compared to professional livestreamers, we are just at the primary stage. I hope more professionals will join us and we can build our brand.”

24、Ever wondered if dogs can learn new words? Yes, say researchers as they have found that talented dogs may have the ability to grasp new words after hearing them only four times.
While previous evidence seems to show that most dogs do not learn words, unless eventually very well trained, a few individuals have shown some extraordinary abilities, according to a study published in the journal Scientific Reports.
“We wanted to know under which conditions the gifted dogs may learn novel words,” said researcher xuekw Claudia Fugazza from the Eötvös Loránd University in Hungary. For the study, the team involved two gifted dogs, Whisky and Vicky Nina. The team exposed the dogs to the new words in two different conditions.
In the exclusion-based task, presented with seven known toys and one new toy, the dogs were able to select the new toy when presented with a new name. Researchers say this proves that dogs can choose by exclusion when faced with a new word, they selected the only toy which did not have a known name.
However, this was not the way they would learn the name of the toy. In fact, when they were presented with one more equally new name to test their ability to recognize the toy by its name, the dogs got totally confused and failed.
The other condition, the social one, where the dogs played with their owners who pronounced the name of the toy while playing with the dog, proved to be the successful way to learn the name of the toy, even after hearing it only 4 times. “The rapid learning that we observed seems to equal children’s ability to learn many new words at a fast rate around the age of 18 months,” Fugazza says. “But we do not know whether the learning mechanisms(机制) behind this learning are the same for humans and dogs. ”
To test whether most dogs would learn words this way, 20 other dogs were tested in the same condition, but none of them showed any evidence of learning the toy names, confirming that the ability to learn words rapidly in the absence of formal training is very rare and is only present in a few gifted dogs.
【1】What was the purpose of the study published in Scientific Reports?
A．To better train dogs’ ability to learn new words.
B．To further confirm previous evidence about dogs.
C．To prove extraordinary memory abilities of gifted dogs.
D．To explore favorable conditions for gifted dogs’ new-word learning.
【2】How did the dogs react when exposed to two new names in the first condition?
A．Slow to understand.
B．Quick to learn.
C．At a loss.
D．In a panic.
【3】What was found about dogs’ new-word learning in the social condition?
A．Learning through playing applied to most dogs.
B．The social condition helped dogs learn new words.
C．Dogs’ new-word learning turned out to be less effective.
D．Dogs shared similar learning mechanisms with children.
【4】Which of the following is the best title for the text?
A．Gifted Dogs Can Learn New Words Rapidly.
B．Dogs Identify Newly-named Toys by Exclusion.
C．Dogs Can Acquire Vocabulary through Tons of Training.
D．Gifted Dogs Have Similar Learning Abilities to Humans.
