2 . 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.”

3 . It all began on a cold, rainy day．

Sarah, a poor single mother, was ________ to make ends meet. While waiting for the bus with her two children, Sarah ________ an old man sitting on a nearby bench. He was shivering (颤抖), his ________ jacket providing little protection against the freezing weather.

Sarah ________ the man and offered him her coat. She knew it would make her cold, but the thought of this stranger ________ while she had something to give was too much to bear. ________ by her selflessness, the man thankfully accepted the coat and gave back a smile. Little did Sarah know that her simple act of ________ would make a huge difference.

A man, who saw the heartwarming ________, took a photo and shared it on social media. The post quickly became a ________, with thousands of people sharing and commenting on Sarah’s ________. Encouraged by her, people began organizing events to ________ those less lucky. Schools added lessons on the ________ of helping others, and businesses started a “pay it forward” project, where people could buy more and leave the ________ meal for those in need.

Reflecting on this unbelievable journey, we can ________ our individual power, which may create an effect that would ________ reach every corner of the globe.

4 . 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.

9 . Ecuadorian writer Veronica Bonilla has received the Special Book Award for 2021, the highest recognition by China for a foreign writer.

At an emotional ceremony held Monday at the Chinese embassy in Ecuador, Bonilla received a golden statuette for her outstanding contribution to promoting Chinese culture.

“I feel-happy, honored and pleased to be the first Ecuadorian to receive this award and also to be the first Latin American to receive it. It is a very important thing. It fills me with pride and happiness,” said Bonilla, visibly moved.

“I am writing about China, a country that I fell in love with when I had the opportunity to get to know it because I want the children of the world to get to know China,” Bonilla said, adding that all the work and effort she has put into her work pays off.

The China Special Book Award has been awarded since 2005 to foreign translators, writers and publishers who have made significant contribution to promoting Chinese culture in the world.

Monday’s ceremony in Quito was attended by Chinese Ambassador to Ecuador Chen Guoyou, and Acting Ecuadorian Vice Foreign Minister Augusto Saa.

Saa said that Bonilla’s work is an example of the value of culture as’ a means of union between peoples. “Our countries have managed to develop an active cultural diplomacy and a powerful soft power tool that has contributed to mutual understanding.”

In congratulation, Chinese Ambassador Chen Guoyou said that Bonilla received the well-deserved award thanks to her long-term dedication to promoting Chinese culture to Ecuadorian children.

“Recent years have witnessed the growing dynamism in the cultural exchange between the two nations through contacts in culture, science, technology, sports, education, among others,” Chen said, noting that relations between China and Ecuador are at the best moment in history.

The Ecuadorian writer has so far translated three of her 83 books into Chinese.
