When we are shopping in a supermarket,
On March 31, 1971, a historic meeting took place in New York City. The meeting agreed
2 . Despite the huge potential of artificial intelligence (AI), it hasn’t caught hold in most industries. Sure, it has transformed Internet companies such as Google, Baidu, and Amazon—all massive and data-rich with hundreds of millions of users. But for expectations that AI will create $13 trillion of value a year to come true, industries such as manufacturing, agriculture, and healthcare still need to find ways to make this technology work for them. Here’s the problem: The script (程序脚本) that these Internet companies use to build their AI systems—where a single one-size-fits-all AI system can serve massive numbers of users—won’t work for these other industries like mentioned above.
Instead, these huge industries will need a large number of custom-built solutions that are adapted to their many diverse use cases. This doesn’t mean that AI won’t work for these industries, however. It just means they need to take a different approach.
To bridge this gap and release AI’s full potential, leaders in all industries should adopt a new, data-centered approach to building AI. Specifically, they should aim to build AI systems with careful attention to ensuring that the data clearly conveys what they need the AI to learn. This requires focusing on data that covers important cases and is constantly labelled, so that the AI can learn from this data what it is supposed to do. In other words, the key to creating these valuable AI systems is that we need teams that can program with data rather than program with code. The data-centered approach to AI, supported by tools designed for building, using, and maintaining AI applications—called machine learning operations (MLOps) platforms—will make AI’s full potential possible. Companies that adopt this approach faster will have a leg up relative to competitors.
Just as electricity has transformed every industry, AI is on a path to do so too. Specifically, a new data-centered approach, coupled with MLOps tools that allow industry domain experts to participate in the creating, using and maintaining of A I systems, will ensure that all industries can get the rewards that AI can offer.

3 . The war epic The Battle at Lake Changjin, one of the most expensive films ever made in China, shot to the top of the weeklong National Day holiday box office, promoting the domestic film market to rebound (反弹) after being inactive for more than two months.
With three outstanding directors—Chen Kaige, Hark Tsui and Dante Lam—the 176-minute-long film follows Chinese People’s Volunteers (CPV) who joined the battle, which turned the tide of the War to Resist US Aggression and Aid Korea (1950-1953).
With the number of cast and crew reaching an unprecedented scale of more than 12,000, the movie recreates the cruel conflict on the Korean Peninsula (朝鲜半岛) amid the extremely cold winter of 1950, when temperatures lowered to the level in 50 years. The movie’s production involved more than 80 visual-effects companies domestically and abroad, with the script being revised 37 times. Breaking over 10 records, the movie has raked in around 2 billion yuan ($ 310 million) since its opening on Sept 30. It accounted for around 75 percent of total holiday income, which had reached 2.67 billion yuan as of Monday, according to the movie information tracker Beacon. The film has also collected millions of reviews and click son several of the country’s most popular social media platforms, including Weibo and Douyin, with most commenters praising the moving tale and saying it stimulates their national pride, making them want to show their respect for the CPV heroes who sacrificed their lives. Some netizens said the film reminds them, amid the current China-US tension, to cherish today’s peaceful life.
Most analysts said the movies’ commercial success has lived up to the industry’s estimation, giving cinema operators a sign of revival. “With a lot of details to recreate historical reality, The Battle at Lake Changjin has raised the bar for Chinese war films to a new high level, signaling the progress that the domestic industry has achieved,” said Rao Shuguang, president of the China Film Critics Association.
But compared with the same period in previous years, the shortage of appealing, medium-budget films has reduced the variety of genres (体裁), which will not be good for the long-term development of the Chinese film industry, Rao added.

4 . In 2011, she gave birth to her son, Sam, six weeks premature. During the birth his heartrate dropped and during the rush to get him out, Gill suffered a major tear which resulted in a permanent stoma (造口), an artificial opening made in her belly.
She was medically retired from her job as a police officer and diagnosed with post-traumatic (创伤后) stress disorder, postnatal depression and anxiety.
It took several years for Gill to find her feet, thanks in large part to exercise and an optimistic outlook. In 2015 she joined a cycling club and has since done a triathlon (三项全能运动), half ironman, scuba diving, sky diving and more. She has also setup a positivity blog and website called Stoma Chameleon which aims to inspire people who have experienced birth trauma or have a stoma.
“When I had my traumatic birth, there was nothing positive out there about how people can recover from something like that,” she explained before taking her latest swim in the lake at Chillingham Castle. “I wanted to show them what is possible and that they’re capable of more than they think.” Her challenge, which involved swimming in the sea at Boulmer or local rivers and lakes, aimed to raise money for the Birth Trauma Association.
“I am getting my bag out and my bikini on to raise awareness of birth injures and stomas,” said Gill. “I didn’t get my bag out in public until June 2020, and now I am putting up a sign on the beach telling my story to strangers, while walking energetically and excitedly in the icy sea.”

6 . Although computer technology is often necessary today, using a pen or pencil activates more areas of your brain than a keyboard does. You can potentially remember more by handwriting, according to a new study.
The potential benefits of handwriting for memory have been debated for some time. The new study set out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?
In all,24 participants took part. Researchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hair net fitted with 256 sensors. Those sensors recorded the participants' brainwaves. The electrodes noted which parts of the brain turned on during each task. And they showed that writing turned on memory areas in the brain while typing didn't.
Audrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is because writing involves complex movements that activate more areas of the brain. The increased brain activity gives the brain more ‘hooks’ to hang your memories on,” she explains. Van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings,” she adds.
This study does not recommend banning digital devices. In fact, its authors point out, computers and other devices with keyboards have become necessary in modern society. Keyboarding can especially benefit those with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.
1. Why were participants asked to wear caps in the study?| A．To record their brainwaves | B．To inform them of their tasks |
| C．To allow them to focus on writing | D．To protect their heads like hair nets |
| A．Why handwriting is more complex than typing | B．Why the brain works when it comes to learning |
| C．Why handwriting helps remember information | D．Why key words are helpful to visual notetaking |
| A．It relieves people's hands | B．It remains vital and helpful |

7 . Imagine the feeling of swinging at a baseball going 100 miles per hour—without leaving your living room, or being in race car as it roars down the track, while you are sitting on the couch.
These are just some of the ways that sports business leaders say virtual reality (VR) will revolutionize how people train for and experience sports. Virtual and augmented（增强的）realities are together known as mixed reality (MR). “American footballers are already using VR to better train their minds and read the field,” Ludden said. “This can allow players to perfect their skills without risking injury.”
Canadian company D-BOX Technologies designs and produces moving seats found in cinema and theme parks. It is now moving into sports, and shows its Formula One (F1) racing simulator （模拟器）. The seats stimulate the force of gravity, speed and every shaking as Fl champion Lewis Hamilton zips around city streets.
A simulation seat uses pre-programed data now. Someday, though, it could use real-time information sent by the car. “They could broadcast live content through a network in pop-up theaters around the world,” Ludden said. Say you want to experience the true stress of a batter being up against major-league baseball pitcher. “You can have a heartbeat added to the sensation on the seat and then you can feel it, boom, boom,” Maheu explained. “When he swings and hits the ball, you can have an impact.”
One day, fans around the world could physically experience every game from their favorite player in real time. Ludden said that current and near-future technology could create “augmented stadiums” for live audiences. Panasonic launched its “Smart Venue” plans which included the overlaying of graphics, advertisements, player statistics and replays on the field of play at a pro football game. “If you are seated in the cheap seats, you can see this really useful.” “Fans may someday join in stadium wide games, using the field as a virtual gaming platform,” Ludden added.

9 . It's no surprise that stress and anxiety are often viewed in a negative light, but Lisa Damour, a private-practice psychologist, suggests they're not always bad for us. She claims that a little bit of both can help build mental resilience and these experiences can sometimes benefit us.
Damour explained how stress often occurs when people operate at the edge of their abilities - when they push themselves or are forced by situations to stretch beyond their familiar limits. This can result from both bad and good events, she said. For instance, being fired is stressful, but so is bringing a baby home for the first time. She described how stress is unavoidable in daily life and that medium levels of stress “can have an inoculating function”, which can lead to “higher than average resilience” when we face new difficulties.
“Anxiety gets an unnecessarily bad comment,” she said, “Anxiety is an alarm system inside the body, likely handed down by evolution, which informs us of threats from both outside, such as a driver turning aside suddenly, and inside, such as when we've wasted too much time and it's time to get started on a task.”
Viewing anxiety as sometimes helpful or even protective allows people to make good use of it, suggests Damour. For example, she often tells the teenagers she works with in her practice to pay attention if they start to feel anxious at a party because their nerves may be warning them of a problem.
1. When do people feel stressed according to Damour?| A．They have much work to do. | B．They lose their favorite things. |
| C．They deal with different situations. | D．They're engaged in doing unfamiliar things. |

| A．To explain the reason for being anxious. | B．To demonstrate the benefits of anxiety. |
| C．To state the risk of being anxious. | D．To present the solution to anxiety. |
| A．Stress and anxiety aren't always bad. | B．Stress and anxiety are part of our lives. |
| C．We should focus on positive things in life. | D．We should deal with stress and anxiety carefully. |
