1 . Have you ever imagined an insect-inspired robot, which weighs less than a gram, could one day help out in surgery (外科手术)?
Scientists have designed this small, “insect-bot” called mCLARI that can control and even change its body shape as it travels in different environments to fit through gaps. It’s 2 centimeters long, weighs less than 0.97 grams and can travel at a speed of 6 centimeters per second.It’s the smaller, faster replacement to CLARI, which was designed by the same team.
“Because of the robot’s small size and ability to change shape, we expect usage of this technology in four important areas,” the lead author Kaushik Jayaram said. These include disaster (灾害) response , check on high-value objects, environmental monitoring and medical treatment.
“In the long term, we hope such robots will be used more widely in moving through human bodies and performing surgeries that can’t be easily done at present,” Jayaram said. With mCLARI, Jayaram’s team is moving closer to creating robots that can fit in different environments—just like the insects they’re inspired by.
The mCLARI robot has four legs and can move in narrow spaces by changing between running forward and side-to-side and can use different speeds in human bodies. Its legs are joined to its body through joints (关节), which enables mCLARI to change its body shape based on the environment it is in. For example, its legs can be lengthened up to 50% in certain spaces.
As follow-up work, the scientists want to give mCLARI more power and sensing ability while helping the surgeries. “We are also excited about understanding the effect of shape change on improving functions of robots,” Jayaram said. “And this is sure a great one-step forward of the technology. The robot will have entered the market by 2025 and will bring greater benefits to mankind, especially in medical treatment.”

2 . A new study, led by Dr. Rebecca Stone, has shown that children as young as four years old eat 79% more calories when they are bored, compared to when they are in a normal mood (情绪) .
The researchers have explored the behaviors that make children more likely to eat when they experience negative emotions. Often when children experience bad emotions such as boredom or sadness, caring adults will use food to soothe them. However, this behavior, known as emotional feeding, appears to increase the possibility of children eating more when they are in low spirits. As time passes, too many calories intake will have a significant effect on children’s health both mentally and physically.
Dr. Stone stresses that the experience of boredom is important in the development of children’s sense of self and creativity, so she does not recommend that children should avoid being bored. Instead, she suggests children learn to experience boredom without turning to food. She also suggests that parents turn their children’s attention away from food when they feel bored, or restructure the home food environment to make it less likely that children turn to food in response to being bored.
While there do appear to be individual differences between children in terms of their eating when bored, it is helpful to know that the feeding practices that adults use around food might shape the likelihood of this happening. Although it is attractive to use food as a tool to help children, emotional feeding might lead to greater emotional eating in the future. It is important for parents and caregivers to be aware that this short-term fix could create future problems.
It is hoped that, on the original basis of the study, the team will deeply explore other negative mood states in children and offer advice and support for families to find more effective ways to manage challenges around children eating behavior.

3 . Mathea Allansmith isn’t your typical grandmother. She’s the oldest woman in the world to have completed a marathon. She was 92 years 194 days old when she crossed the finish line at the 2022 Honolulu Marathon, setting the record for the oldest female to complete a marathon.
Mathea, now 94, of Koloa, Hawaii, USA, stays in shape all year round by running seven days a week, no matter what the weather is. Come rain or shine, she covers 36 miles every week, even when she’s on holiday. The retired doctor didn’t take up running until she was 46 years old —after a friend suggested running two miles per day.
“The Honolulu Marathon is my favorite marathon mainly because it doesn’t close the gate at a certain time, which allows even the slowest runner to finish the race,” she said. “It’s one of the best races. Fantastic registration (注册), set-up and management make it a joy to run the race.”
Mathea, who doesn’t allow her age to slow her down, thinks she is the happiest person when she’s on the road. She enjoys running for miles and waving and saying hello to the people she passes. To stay in shape, Mathea keeps a steady training routine (惯例) . “I train all year round but increase the mileage 18 weeks before a marathon,” she said.
Mathea said it was her career as a doctor that allowed her to understand how her body and mind respond to diet and exercise. “I see the direct relation between moving and health,” she said. “It is important to reduce stress rather than ignoring it without a plan on how to do so. Of course, exercise of any kind is a natural stress reducer.”
Mathea thought getting through the finish line and winning a Guinness World Record title was the excitement of her life. “My family completely surprised me after the 2022 Honolulu Marathon, in which I achieved the world record, by wearing matching T-shirts stating my achievements,” she said.

4 . Culture shock is the experience that often accompanies moving to an unfamiliar place. It could be marked by feeling lost, anxious or hesitant.
When deciding to visit an entirely new place, don’t expect the traditions and cultures followed by your current home to be followed by the new land.
Even though it is an unfamiliar environment hosting different cultures and traditions from the one you’re used to, it’s vital to broaden your mind and be willing to try new things. Don’t be quick to form discriminatory judgments just because it is “odd”. Have a go at something different, like a food or clothing — different isn’t necessarily bad.
Social psychologists claim that lack of information is the biggest contributor to prejudices. Talk to the local population and ask them about how their culture works instead of assuming the worst.
Keep yourself open-minded, await new experiences and familiarize yourself with the conduct of the people.
| A．Integrity breaks down barriers. |
| B．You can gain insight into your surroundings. |
| C．Culture shock will eventually disappear, though. |
| D．Every city or country has its own values and beliefs. |
| E．Never do you know where you might find an interest. |
| F．Consequently, such memories are what you should treasure. |
| G．As long as you stick to that, you’ll soon adjust to the new culture. |
5 . There are many differences in ways of thinking between East and West. Many of them are reflected in daily behaviour. In particular, Chinese people sometimes attach more importance to their appearance and social status than to their inner qualities, while Westerners think the opposite. However, Socrates (Ancient Greek philosopher) and Confucius share significant similarities that are universal.
Both philosophers share several teachings in common; for example, their understanding of the nature of knowledge and their opinions on education. Socrates believed “There is only one good, knowledge;and only one evil, ignorance.” Similarly, Confucius said, “Isn’t it a pleasure to study and practice what you have learned?” But both also acknowledge the limits of knowledge. Socrates said: “All I know is that I know nothing.” Similarly, Confucius said, “When you know a thing, to hold you know it; when you don’t know a thing, to allow you don’t know it-this is knowledge.”
However, there are important differences in their understanding of morality. Confucius believed each person should follow certain regulations according to virtue(德行). Everyone should play their role in a society where people are interdependent in order to achieve harmony in the whole society. For instance, when asked how to govern a country, Confucius stated “An emperor should act like an emperor, a subject should act like a subject.” Socrates, however, places self-knowledge over social knowledge.
Another difference between them is their attitude towards political domination(支配). Confucius believed the best way to govern a country isn’t through legal system, but through virtue. Socrates, by contrast, declared that “nothing is more important than justice”.
Why have East and West developed such different cultural values? A widely accepted theory holds that Eastern civilization was an agricultural civilization. Hence the need for a collective society and friendly relations with neighbors was strong. Western civilization, however, was nomadic(游牧的). Their mobility makes them less dependent on society after migration.
In spite of their differences, the two cultures have more in common than differences. The shared concern for moral values in the teachings of Socrates and Confucius also shows us more fundamental similarities between Eastern and Western cultures in their pursuit of virtuous lives.

6 . It’s often said that we human beings can dream in a foreign language. Could dreaming in a foreign language improve our memory? Does dreaming in a foreign language mean we are making progress in learning that language?
Before we look at multilingual (多语言) dreams, first we need to look at sleep. The connection between sleep and language can be applied to how we learn any language, including our native language. Even adults still learn about one new word every two days in their first language. But, if we are going to remember that new word better, what matters is that we need to connect it with what we have learned. And in order to do that, we “need to have some sleep”, says Gareth Gaskell, a professor at the University of York.
It’s during sleep that the integration (整合) of old and new knowledge happens. At might, one part of our brain — the hippocampus — takes whatever new information it receives during the day and passes it on to other parts of the brain to be stored. The role that dreams play in this night-time learning process is still being studied, but “it’s entirely possible that during multilingual dreams, the brain is trying to connect the two languages”, says Marc, a researcher at a university in Bern, Switzerland.
So having multilingual dreams could mean that our brain is trying to remember a new word or phrase. However, it could also have an emotional (情感) significance. Danuta, a professor of psycholinguistics at the University of Silesia in Poland, suggests that multilingual dreams can express “fears or wishes” around learning a foreign language, including the wish to be a local speaker or to be accepted within a certain community.
We clearly still have a lot to learn about multilingual dreams, but one thing seems certain: if you’re trying to learn a new language, you can sleep on it.

7 . Travelling with friends can be an amazing experience where you could make lifelong memories or it could ruin your friendship.
Communicate and respect each other. Everyone has personal preferences when travelling— from getting the bed closest to the bathroom or sitting in the airplane’s window seat. But sometimes things don’t go as you like. In this case, share your requirements directly with your travel companions.
Don’t disappear. When travelling with a group — or even just one other person — you may want some alone time. That’s completely fine, but make sure your friends know where you are and have a way of contacting you.
Get off your phone. Of course, your friends will understand if you need to take a call from a family member, or in the event of a work emergency, but other than that, try to stay off your phone.
| A．Give each other some space. |
| B．Include at least one activity for everyone. |
| C．So it’s important to make sure you and your friend(s) are on the same page. |
| D．At the same time, listen to their concerns and be respectful of them. |
| E．Don’t respond to less important work contact or send messages frequently. |
| F．It’s especially true of travelling in foreign countries or unfamiliar places. |
| G．And remember that consideration and respect go a long way. |
8 . Your neighbors are probably the first line of defense in case of any problematic situation.
The first step is introducing yourself when you move to a new neighborhood or when a newcomer moves in. Leave them a note under their door to introduce yourself.
Be respectful of your neighbors. It’s in poor taste to have regular insensitive parties at your place causing disturbances. Before your party, it’s good practice to notify your neighbors. Besides, avoid chatting them up for hours on end, which may be inconvenient, especially if you don’t know their schedules.
As Emma Seppälä put it, “social connectedness generates a positive feedback loop (圈) of social, emotional and physical well-being.” It feels so easy to just stay home without having to engage with your neighbors but connecting with them is worth the effort.
| A．Remember every small gesture counts. |
| B．A crisis is a test of communication skills. |
| C．It can actually boost your mood in the long run. |
| D．Slipping it in their mailbox further solidifies friendship. |
| E．It’s essential to ensure you maintain decent relationships with them. |
| F．Alternatively, you can give them a gift while making yourself known to them. |
| G．Only by establishing healthy boundaries will you achieve peaceful coexistence. |
9 . Jimmy Jiang envisions a future where every house is powered by renewable energy stored in batteries.
Jiang and his team at the University of Cincinnati have developed a new battery that could have far-reaching implications for the large-scale (大规模) energy storage needed by wind and solar farms.
“Batteries store renewable energy for when it’s needed, not just when it’s produced. This is crucial for getting the most out of wind and solar power,” Jiang said. “Energy generation and energy consumption is always mismatched. That’s why it’s important to have a device that can store that energy temporarily and release it when it’s needed.”
They described their novel design in the journal Nature Communications.
Traditional car batteries contain a mix of sulfuric acid and water. While they’re inexpensive and made from readily available materials, they have severe drawbacks for industrial or large-scale use. They have a very low energy density (密度), which isn’t suitable for storing sufficient power needed to power a city. And they have a low level for electrochemical stability, which means they can blow up.
Water has a voltage (电压) limit. Once the voltage of such a battery goes beyond the stability window of 1.5 volts, the water can decompose into hydrogen and oxygen, which is explosive.
But Jiang and his students have developed a battery without water that can generate nearly 4 volts of power. Jiang’s novel design does so by removing from a battery the membrane, which is a huge component of upfront costs and accounts for as much as 30% of the cost of the battery. They invented a new type of energy storage material that improves performance at a lower cost. “Membranes are also inefficient. They can’t separate the positive and negative sides completely, so there is always crossover,” he said.
The group has submitted temporary patent applications. “There is still a long way to go, but we’re advancing toward a dramatic battery transformation in the next decade. I’m confident about that. There is a lot of intense research going into pushing the boundaries of battery performance,” Jiang said.
