1 . Cows love having an open area of grassland. But in some parts of the world, this is only feasible during the summer. In the winter months, it can become too cold for cows to safely stay outside, so they are kept in a large farm building for warmth. Being kept inside is not always enjoyable for the cows, and their unhappiness is closely connected to less milk production.
For this reason, some cow owners have fitted their cows with VR headsets that run a program specially. The program simulates (模 拟) grassland in summer and was designed for the way that cows get color and light. According to the National Library of Medicine, cows see red most easily but have a hard time telling the difference between blue and green.
Reports from a farm in Moscow, Russia — where the VR headsets were first developed by vets — found in 2019 that the cows that used the VR headsets saw a decrease in anxiety and an improved mood. This led to an increase in milk production, which went from 5.8 gallons to 7 gallons a day.
The cow owner Izzet Kocak from Aksaray, Turkey, heard about this experiment and tried the VR headsets on his cows in December 2021. When Kocak put the headsets on his cows, he found an improvement in the moods of his animals. “They are watching an area of grassland, and it helps lift their spirits. They are less stressed,” he said.
The technology is now being used around the world. According to the BBC, the headsets were made specifically for the“ structural features of cow heads” by vets, and the animals were shown a “unique summer field simulation program”. The familiar sight of an area of grassland is enough to improve the mood of the animals
Ministry of Agriculture of the Russian Federation says that research has shown a connection between a cow’s mood and its milk production. They said, “Examples of dairy farms from different countries show that in a calm atmosphere, the amount of milk increases greatly.”

2 . Our friends Nick and Carol moved to Australia in 2017. My husband and I finally saved up enough money to visit them in Sydney.
From the very first day, I had this feeling that here was a place where I could imagine fitting in. We had left England in the cold and rain, and arrived to find Sydney warm and sunny. We spent our days relaxing on the beach, or going into the city to explore.
Slowly, we started talking about the idea of moving to Australia. We’d had enough of short, cold, wet days and small houses in England. The crowds and queues of people at home were too much.
Immigration (移民) to Australia is a long process and expensive. It was very exciting when our applications were finally accepted. When we arrived, and flew over the city of Perth, I saw the bright sunshine and the spacious houses and swimming pools below.
There are things I miss about England of course, but I do enjoy all the space in Australia, and the relaxed outdoors lifestyle.
A.It was time for a change. |
B.I saw forests and countryside, too. |

6 . Playing with my 5-year-old child, I sometimes wonder: Why are her made-up games so terribly boring? In Learning to Imagine, psychologist Andrew Shtulman thinks it untrue that kids are uncontrolled wellsprings of imagination. On the contrary, the more we learn, the more imaginative we can become, and learning will not hold back imaginative ideas. Kids, he argues, fail to imagine obvious possibilities.
To gather evidence for this argument, Shtulman explores mechanisms (机制) for expanding imagination. Without support of others or new tools and technologies, people may reject reasonable ideas out of hand, he maintains. Lord Kelvin, for instance, famously denied the possibility of “heavier-than-air flying machines” less than 10 years before the Wright brothers created one. Abstract principles, like those so influential in science and ethics (伦理学), also boost imagination. Finally, imagination grows through exploring alternative models of the world, as in plays, fiction and so on. Across all of these examples, expanding imagination requires building closely on what people already know.
Perhaps counterintuitively (反直觉地), kids relate best to realistic stories. For instance, Walt Disney’s earliest cartoons were disorganized and strange. Only when the cartoons became “reasonably impossible” did they gain mass appeal. Many fictional worlds, from Middle Earth to Hogwarts, rely on reasonable impossibility.
Shtulman cleverly and precisely sails this vast, attractive sea. Learning to Imagine never drags or makes me get stuck on professional words. I wish, however, that there had been more focus on what these findings mean. If education does not hinder imagination, how do we develop it? Shtulman advises us to “engage with, and learn from, the collective knowledge of other people”. AI programs like GPT take that approach, educating themselves on massive data sets.
“Be like GPT” is not the most heartening message. But while humans cannot learn large amounts of data quickly and easily like AI, human imagination is shared and cooperative. That, at least, is something all of us—5-year-olds and their dads alike-have over the chatbots.

C.Children are full of it. | D.Inventions are based on it. |
A.Known information. | B.Realistic principles. |

7 . As China’s cities grow, they are also sinking. An estimated 16 percent of the country’s major cities are losing more than 10 millimeters of height per year and nearly half are losing more than 3 millimeters per year, according to a new study published in the journal Science.
“Land subsidence (下沉) is a problem that almost exists everywhere,” said Robert Nicholls, a climate scientist and civil engineer at the University of East Anglia who reviewed the paper, “To my knowledge, this study is the first to measure land subsidence across many urban areas using state-of-the-art radar (雷达) data from satellites. I believe the majority of the adaptation strategies that we have, and the plans to fight climate change, are inaccurate, just because they did not include land subsidence. Land subsidence is an unheeded problem. It hasn’t been studied the way, for example, sea level rise has been studied.”
The new study was based on satellite radar measurements of how much the ground surface in 82 major cities, accounting for three-quarters of the urban population, moved up or down between 2015 and 2022. The researchers compared these measurements to data on potential contributing factors. Subsidence in these cities is caused in part by the pure weight of buildings, the study found. Groundwater extraction (开采) underneath the cities also plays a role, as do oil drilling and coal mining. These activities leave empty space underground where soil and rocks can press together or collapse.
Being below sea level doesn’t mean a city is automatically destroyed. Much of the Netherlands is below sea level and sinking, but the country has been extensively engineered to prevent flooding in places and to accommodate it in others. Shanghai is already limiting groundwater extraction and is sinking more slowly than other cities. In Japan, groundwater management over the years has proved successful. “It’s difficult to stop subsidence entirely,” Dr. Nicholls said, “You’ve got to live with what’s left. “

10 . Is diet soda safe? If you’re concerned about sugar, diet products seem a better option, sweet and not so bad for you. Wrong! Drinking diet soda regularly can increase your risk of diseases. Despite the fact that we call these drinks “diet”, the artificial sweeteners they contain are linked to weight gain, not loss.
There’s the latest evidence that they increase the risk of depression, which comes from a new analysis by researchers at Harvard Medical School. The team drew upon a data set of nearly 32,000 female nurses, ages 42 to 62 when the study began. It turned out that the nurses who consumed the most diet drinks had a 37 percent higher chance of depression, compared to those who drank the least or none.
Diet soda also increases your risk of stroke (中风), according to a separate meta-analysis that included 72 studies. Looking for the causes behind the stroke, researchers took various blood measurements when 12 healthy volunteers in their 20s drank water, soda, or diet soda. The result showed that both sodas slowed the flow of blood within the brain. Though the effect didn’t seem sufficient to cause stroke, slower blood flow could have accumulating effects.
Other researchers have found that diet soda increases the risk of dementia (痴呆), from data from nearly 178,000 volunteers tracked over an average of nine years. That’s not a big surprise. An earlier study of about 4,300 volunteers concluded that drinking diet soda every day was tied to three times the risk of dementia over the following decade. The researchers looked at brain scans and the results of mental function assessments. A daily diet soda was linked to smaller brains and aggravates long-term memory, two risk factors for dementia.
Avoiding depression, stroke, and dementia is an obvious goal for whoever desires to age healthily. So you know what to do.
