(2025.9.8高三周考)Anyone who has taken a standardized test knows that writing an essay in 20 minutes or less takes serious brain power. Having access to artificial intelligence (AI) would certainly lighten the mental load. But as a recent study by researchers at the Massachusetts Institute of Technology (MIT) suggests, that help may come at a cost.
Over the course of a series of essay……Across the board, the AI users exhibited markedly lower brain activity in areas associated with creative functions and attention.
Whether AI will leave people’s brains weak in the long term remains an open question. Researchers ……After all, the study had a tiny sample size and focused on a single narrow task.
Moreover, generative ……Calculators spare cashiers from computing a bill. Navigation apps remove the need for map - reading. And yet few would argue that people are less capable as a result.
There is little evidence……But the worry is that generative AI allows one to offload a thought process…….As one user put it, “I rely so much on AI that I don’t think I’d know how to solve certain problems without it.”
The technology is so young that, for many tasks, the human brain is still the sharpest tool in the toolkit. But in time both the consumers of AI and its regulators will have to assess whether its wider benefits outweigh any cognitive (认知) costs. If stronger evidence emerges that AI makes people less intelligent, will they care

(2025.9.5高三入学考试)Clean air policies have unintended impact—driving up wetland methane(甲烷)emissions by up to 34 million tons. Reducing sulphur(硫)in the air may increase natural emissions of methane from wetlands, a new study has found.
The findings suggest that the decline of global sulphur emissions as the result of clean air policies……emissions.
The resulting additional future release of 20 million - 34 million tons of methane each year ……caused emissions need to be more stringent than currently set out in the Global Methane Pledge.
Methane, which is one of the most powerful greenhouse gases in trapping heat in the atmosphere……producing micro creatures.
Professor Vincent Gauci from the University of Birmingham, a senior author of the study, said…… This, coupled with increased CO , means we have a double whammy(晦气)effect that pushes emissions much higher.”
How has this happened Put simply, sulphur provides the conditions for one set of bacteria to outmuscle another set of …this was enough to reduce wetland methane emissions by up to 8%.

(2025年全国一卷C篇)While safety improvements might have been made to our streets in recent years, transport studies also show declines in pedestrian (行人) mobility, especially among young children. Many parents say there’s too much traffic on the roads for their children to walk safely to school, so they pack them into the car instead.
Dutch authors Thalia Verkade and Marco te Br mmelstroet are bothered by facts like these. In their new book Movement: How to Take Back Our Streets and Transform Our Lives, they call for a rethink of our streets and the role they play in our lives.
Life on city streets started to change decades ago. …… Australia in the late 1960s and 1970s as well.
Although these campaigns were widespread……among the highest rate of car ownership in the world.
We invest a lot in roads that help us rush through, but we fail to account for the true costs. Do we really recognize what it costs us as a society when children can’t move safely around our communities The authors of Movement have it right: it’s time to think differently about that street outside your front door.

(2024年新课标高考英语II卷C篇)We all know fresh is best when it comes to food. However, most produce at the store went through weeks of travel and covered hundreds of miles before reaching the table. While farmer’s markets are a solid choice to reduce the journey, Babylon Micro-Farm (BMF) shortens it even more.
BMF is an indoor garden system. It can be set up for a family. Additionally, it could serve a larger audience such as a hospital, restaurant or school. The innovative design requires little effort to achieve a reliable weekly supply of fresh greens.
Specifically, it’s a farm that relies on new technology. By connecting through the Cloud, BMF is remotely monitored. Also, there is a convenient app that provides growing data in real time. Because the system is automated, it significantly reduces the amount of water needed to grow plants. Rather than watering rows of soil, the system provides just the right amount to each plant. After harvest, users simply replace the plants with a new pre-seeded pod (容器) to get the next growth cycle started.
Moreover, having a system in the same building where it’s eaten means zero emissions (排放) from transporting plants from soil to salad. In addition, there’s no need for pesticides and other chemicals that pollute traditional farms and the surrounding environment.
BMF employees live out sustainability in their everyday lives. About half of them walk or bike to work. Inside the office, they encourage recycling and waste reduction by limiting garbage cans and avoiding single-use plastic. “We are passionate about reducing waste, carbon and chemicals in our environment,” said a BMF employee.
What does the text mainly talk about
A. BMF’s major strengths. B. BMF’s general management. C. BMF’s global influence. D. BMF’s technical standards.

(2025全国2卷C篇)When Sonja Detrinidad opened her online shop selling houseplants, she didn’t have high hopes for it. But the opposite happened: She was flooded, shipping out 1,200 orders in June of 2020 alone. In the past year, Detrinidad sent out more than 70,000 plants. Her success is just one example of increased time at home leading to an explosion in the houseplant industry.
“Plants are in fashion right now,” says Dr. Melinda Knuth, a researcher from the University of Florida. “People who live in plant-rich environments report a higher life satisfaction rating, ” she says. “Adding more nature to our environment can change our mood and how we think.” Plants can improve our state of mind in a few ways but the biggest is by decreasing our level of cortisol, the stress hormone (激素) in our body.
“Students who are around plants perform better academically than students who are in a classroom without plants,” says Knuth. “This productivity also translates into the workplace for adults. Our study showed that there was a 30% decrease in sick leave for people who were in plant-rich workplaces.”
If you’re among the groups of people who are enjoying the mental and physical health benefits of surrounding yourself with plants, don’t beat yourself up if one (or a few!) doesn’t make it. “Doctors practice medicine and lawyers practice law and you should allow yourself the practice it takes to sustain a plant. Tending to plants is an exercise in patience and learning. Be invested in taking care of it, but if it dies, go get another one,” Detrinidad says.

(2024年全国高考英语甲卷B篇)Animals can express their needs using a lot of ways. For instance, almost all animals have distinct vocals (声音) that they rely on to either ask for help, scare away any dangerous animals or look for shelter. But cats are special creatures who possess amazing vocalization skills. They are able to have entire conversations with humans using meows and you're able to interpret it. If a pet cat is hungry, it will keep meowing to attract attention and find food. However, when a cat is looking for affection, they tend to produce stretched and soft meows. Meowing starts as soon as a baby cat is brought to life and uses it to get the mother's attention and be fed.
Cats have many heightened senses, but their sense of smell is quite impressive. They use their noses to assess their environment and look out for any signs of danger. They will sniff out specific areas before they choose a place to relax. However, another way the cats are able to distinguish between situations is by looking for familiar smells. Your cat will likely smell your face and store the smell in its memory and use it to recognize you in the future. That's why most pet cats are able to tell immediately if their owners were around any other cats, which they don't usually like.
Dogs are known for their impressive fetching habit, but cats take this behavior up a notch. Many cats will find random objects outside and bring them to their owners. This is a very old habit that's been present in all kinds of predators (食肉动物). Cats bring gifts for their owners to show they love you. These adorable little hunters are just doing something that it's been in their nature since the beginning of time. So just go along with it!

【2024·九省联考卷】For lots of kids, toddlerhood (幼儿期) is an important time for friendship. Studies show that the earlier kids learn to form positive relationships, the better they are at relating to others as teenagers and adults. Playing together also helps these kids practice social behaviors, such as kindness, sharing, and cooperation.
Even so, how quickly your child develops into a social creature may also depend on his temperament (性格). Some toddlers are very social, but others are shy. In addition, the way' that toddlers demonstrate that they like other children is markedly different from what adults think of as expressions of friendship. Research at Ohio State University in Columbus found that a toddler’s way of saying “I like you” during play is likely to come in the form of copying a friend’s behavior.
This seemingly unusual way of demonstrating fondness can result in unpleasant behavior, Regardless of how much they like a playmate, they may still grab his toys, refuse to share, and get bossy. But experts say that this is a normal and necessary part of friendship for kids this age. Through play experiences, toddlers learn social rules. That’s why it's so important to take an active role in your toddler’s social encounters by setting limits and offering frequent reminders of what they are. When you establish these guidelines, explain the reasons behind them.
Begin by helping your child learn sympathy (“Ben is crying. What's making him so sad ”), then suggest how he could resolve the problem (“Maybe he would feel better if you let him play the ball.”). When your child shares or shows empathy (同理心) toward a friend, praise him (“Ben stopped crying! You made him feel better.”).
Another way to encourage healthy social interaction is by encouraging kids to use words -- not fists -- to express how they feel. It's also important to be mindful of how your child's personality affects playtime. Kids are easy to get angry when they’re sleepy or hungry, so schedule playtime when they’re refreshed.
