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.

Every October, my neighbor Ollie and I would enter the Halloween costume contest (服装比赛) in our neighborhood park．And each year the theme was different, such as “Superheroes” or “Far m Animals”．But this year’s theme was not so specific．It was just “Be Creative”．
Walking home along the road lined with tall trees, the two of us had a heated discussion about what “Be Creative” meant．We looked back on the themes we had really enjoyed．For “Superheroes”, we made costumes of Super-Force Flying Eagle．And for “Farm Animals”, we were dressed as a cow and a horse．Ollie even put a pair of wings for the horse, saying that he’d love to see a “flying horse” eating grass with a cow on the farm．
“Now that’s the creative spirit we need for this challenge!” I said．“Maybe, since we don’t know exactly what we want to be yet, we should start by choosing some cool costume-making materials.”
Just at that moment, a falling golden leaf happened to have landed on Ollie’s shoulder．“I’ve got it!” Ollie said joyfully, picking up some fallen leaves from the ground．“We can make costumes out of leaves and pretend to be trees．I can ensure, no one will be a tree as great as me.”
“Oh, that’s wonderful!” I said．“I like your creative idea and I have just got a perfect way to be another tree.”
We filled up two bags with different kinds of leaves: Ollie’s grandma, Abuela, an experienced tailor (裁缝), helped us with tons of excellent costume-making supplies and we started to work．When we were done, we each tried on the self-designed costumes and they were really wonderful．On the morning of the contest, we got up early and spent hours making preparations．We arrived at the park early and waited for our turn nervously and eagerly．

6 . Here are some ways you can change your inner thoughts to stop stress having an effect on your mental and physical health.
ExerciseExercise can be used as a tool to enable you to deal with stress. The feel-good chemicals released(释放)by the brain when you exercise give a sense of well-being and calm.
Having some people who support you helps you to feel calm. When you meet with difficulties, there are people who will have your back. You feel much less stressed when you have friends and family on your side. Build your support network by giving to others when they need you.
Tiredness, the inability to think straight and sleep deprivation (缺乏) make you feel stressed. Improving sleep quality itself does a lot in reducing stress.
Make sure you are giving yourself some time in your week.
| A．Be really strict with work-life dividing line. |
| B．Don’t be afraid to ask for the same in return. |
| C．It’s of great importance to choose someone you trust. |
| D．Put aside some screen-free time before going to bed. |
| E．Be organized, prepared and on time for jobs that matter to you. |
| F．People often care about what doesn’t go right instead of what goes well. |
| G．Challenging yourself to keep working out can make you build self-respect. |
7 . UC Berkeley Youth Summer Camps
UC Berkeley Youth Summer Camps will provide a wide variety of one-week outdoor experiences and activities for young people on summer camps 2024. Here are four best summer camps.
Afternoon Adventures CampAfternoon Adventures Camp offers many adventurous activities around the Berkeley Marina. Campers must be aged 8-10 to sign up. They will explore the ocean plants and join in other activities such as doing outdoor exploration, playing outdoor group games and going skateboarding. This camp provides an opportunity for younger campers to develop lasting friendship through outdoor games.
Blue CampBlue Camp grew from the idea that all children need opportunities to take part in regular physical activities to support their mental health. This camp for children aged 7-12 includes art trainings, swimming lessons, free play and group games to create a fun and well-rounded camp experience. The camp is made up of three age groups to ensure safety.
Eco(生态)Adventures CampEco Adventures Camp allows campers to have the chance to explore various environments around Berkeley. Campers will practice observing through their senses and record their findings while they use scientific methods to explore various creatures of the Bay Area.
Discovery CampDiscovery Camp is designed specifically with the 10-12 year-old in mind, with challenging new ways to explore the Bay Area. Activities may include hikes(徒步旅行)to regional waterfalls, cycling to a beach picnic lunch and rock climbing. The full day course covers a series of regional adventures, often with several stops in a day. All campers can enjoy the bus service to and from the campsites.

8 . 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. |
9 . 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.
1. What do the two philosophers share about knowledge?| A．The learning of knowledge is easy. | B．The learning of knowledge is endless. |
| C．A man without knowledge is foolish. | D．A man shall not pretend to understand. |
| A．Nothing is more important than a legal system. |
| B．I am not a Chinese, but a citizen of the world. |
| C．Not everyone should play his own role in society. |
| D．A man does what is proper to the position he is in. |
| A．The difference in political atmosphere. | B．The difference in the length of history. |
| C．The difference in economic development. | D．The difference in levels of social dependency. |
| A．Reasons for similarities of Eastern and Western cultures. |
| B．The introduction of great figures of two different cultures. |
| C．Comparisons of the thoughts of the two great philosophers. |
| D．The contributions of two great philosophers to civilization. |
10 . 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.
