1 . When you have to cancel your Thanksgiving plans due to the spread of the COVID-19, you may find yourself craving companionship as much as that pumpkin pie. That’s because parts of the brain respond to loneliness much like they react to hunger, according to a study in Nature Neuroscience.
Researchers from the Massachusetts Institute of Technology scanned the brains of 40 healthy, social young adults after 10 hours of either fasting (禁食) or social isolation (隔离). They found that after being alone, participants’ neurological responses to social signals were similar to hungry people reacting to food — that is, certain areas of the brain linked to desire were turned on to start working.
For an isolated person, a picture of people laughing together caused the same areas of the brain to light up as when a hungry person looked at a big plate of pasta.
“Just like hunger is an unpleasant sensation that motivates us to seek out food and thirst motivates us to seek out water, loneliness is a biological need that motivates us to reconnect to others,” Holt-Lunstad told Insider.
Researchers were surprised to find that people who were prevented from socializing became much more focused on that need, and less reactive to hunger. As their loneliness increased, they became less responsive to images of food.
These latest findings suggest that the relationship between food and loneliness might be more complicated than we thought, despite the popular opinion of stress-eating to cope with social isolation. More research is needed to understand the complex ways people deal with loneliness.
Studies like this can help scientists understand how the brain processes loneliness, and possibly reduce the negative consequences. However, although loneliness may be similar to hunger, fixing it isn’t as easy as serving someone a hearty dinner because people are unique and they need varying levels of social interactions to meet their needs.

2 . Watching movies is great for improving your English. And if you choose films that you enjoy watching, you’ll learn English without even realising it! Here are four movies that are perfect for English learners.
Charlotte’s Web (2006)Story: The power of friendship between a pig(Wilbur)and a spider(Charlotte).
The live-action film, a fine adaptation of E. B. White’s book, will entertain the young audience with cute talking animals and easy-to-follow language. Adults will also be charmed by heartwarming good time and learn to look at the world with curiosity and joy.
Toy Story(1995)Story: A cartoon film about toys that come to life when children and adults aren’t around.
The storylines are clear and the characters use simple but useful language. Though it’s mainly for kids, Toy Story doesn’t feel childish. The story and jokes also attracted adults, so parents would be more likely to take their children to see the film.
Charlie & the Chocolate Factory (1971)Story: Things go wrong when a group of kids get a free tour of Willy Wonka’s chocolate factory.
This film is also great for English learners as it is generally easy to follow. And you’ll hear some extracts(选段) from English literature because Willy often quotes well-known writers such as Oscar Wilde and Shakespeare.
The Sound of Music(1965)Story: A young woman (Maria) becomes the nanny for seven children in a house in the Austrian Alps.
The Sound of Music is a musical and listening to music is one of the best ways to improve your English. Many of the film’s songs have become classics because they’re so catchy.
1. Which movie attracts cartoon lovers most?| A．Charlotte’s Web(2006). | B．Toy Story(1995). |
| C．Charlie & the Chocolate Factory(1971). | D．The Sound of Music(1965). |
| A．They are preferred by housewives. | B．They are musicals. |
| C．They are based on classic works. | D．They have children characters. |

3 . Imagine a school where students are taught by the best teachers in every subject, regardless of location. Imagine a school where students could go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual(虚拟的)reality.
Last year, Optima Academy Online, an all-virtual school, delivered courses that aim to improve the hearts and train the minds of young people. These courses are of different levels, attracting 170 full-time students from all over Florida. In the progress of home-schooling, students use headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins.
Future versions(版本)of VR will doubtless be widely used in education, but the only questions are: for what purpose and at what speed? There are enough reasons to doubt whether VR schools represent the future of education. Sticking a child in their bedroom with a heavy VR headset fastened to their face and no physical social interaction with other kids will fill many of them and their parents with horror.
A recent report concluded that digital education could significantly improve the quality and equality of schooling systems. But if managed poorly, it could have the opposite effect, turning a digital divide into an educational one. There is growing evidence to suggest that is happening. In Mexico, only 24 percent of 15-year-old students in poor schools have access(使用)to a home computer for schoolwork compared with 87 percent in rich ones.
Used properly, technology can be great for enabling self-motivated students to access learning resources and connect with fellow students and teachers all over the world, says Beeban Kidron, a member of the UK’s Digital Futures Commission. The trouble is that Edtech is too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a different way to learn, she adds.

4 . The Power of Insensitivity
Highly sensitive(敏感的)person, or HSP, is a term invented by psychologist Elaine Aron. HSPs can come with many challenges. They may find it hard to adapt to new surroundings, and easily become uncomfortable in response to certain feelings or others’ opinions.
The power of insensitivity can be explained as “slow power”. Usually, people connect “insensitivity” with something bad, but indeed, it stresses the ability to keep doing something difficult without complaining.
There are some ways to practice “insensitivity”: Don’t pay too much attention to the ups and downs of life at the moment.
Everyone can gain the ability to be insensitive.
| A．Insensitivity plays a significant role. |
| B．Rather, you should be looking forward. |
| C．That’s where the need to be insensitive comes from. |
| D．Once you slow down the pace, you will feel more comfortable. |
| E．Those not easily affected are the people who care less about others. |
| F．That is, calmly facing the downtime in life and moving towards one’s own direction. |
| G．One reason why insensitivity allows people to better survive is the strong self-awareness. |
5 . How to Protect Against Undue Influence Online
The potential for undue influence has become increasingly significant in this era of digital interconnectivity. Undue influence can affect our perceptions and influence our decisions. It may even end anger our autonomy (自主) and mental health.
Understand what undue influence is
The first step to protecting yourself is understanding what undue influence is. Undue influence refers to a situation in which an individual or group employs unreasonable control over another person’s behavior information, thoughts, and emotions.
Develop media literacy skills
In an age of fake news, it is crucial to develop media literacy skills.
Delete as much data as you can about yourself. Be mindful of what information you share online, and always ensure that your online activities are secured through reliable sources. Review all policies on platforms, especially “free” ones. If you aren’t paying, then you are the product, as in many cases, they are selling your data.
By including these steps into your digital life, you can protect yourself from undue influence in the online world, ensuring that you can think and act independently, free from ill control.
| A．Prioritize privacy |
| B．Be mindful of free ones |
| C．It’s vital to have a health y Internet and real-life balance. |
| D．In the digital world, undue influence can take many forms. |
| E．Everyone deserves the right to live free from undue influence. |
| F．They involve analyzing, evaluating, and creating media in various forms. |
| G．Here are some essential strategies for you to protect yourself online from undue influence. |
6 . Towards the end of the 1985 sci-fi classic Back to the Future, the inventor Doc Brown announces “where we’re going, we don’t need roads as the car lifts into the air”. While flying cars aren’t yet filling our skies, many are in development. In October the Chinese XPeng X2 successfully completed the first public test flight of its two-seater flying car in Dubai.
The XPeng X2 lifts vertically off the ground using eight propellers (螺旋桨), without the need for a runway, and is therefore suitable for built-up city areas. The vehicle, designed to carry two passengers, is fully electric and its makers say it can rise through the air at around two meters per second and then reach speeds of up to 80 miles per hour. The XPeng X2 is equipped with AI automation — it can be set to self-drive. It learns how to avoid traffic, buildings and people. It does not produce any carbon dioxide emissions during flight and is a step forward in the pursuit of urban green transportation. It is suitable for future low-altitude city flights and is perfect for short-distance city journeys such as sightseeing and medical transportation.
Although the test flight lasted just 90 seconds, according to Dr. Liu, chief aviation specialist at Xpeng Aeroht, the technology is close to being ready for public use, but regulations on flying cars are still some way off. Liu believes that people will be able to use flying cars within limited regulated spaces in just five years. This lines up pretty well with the Chinese government’s plan to put flying taxis on the market by 2025. The self-driving function presents further difficulties with regulation and also throws into question public acceptance. Many people are worried about the safety issues around self-driving cars on the ground, let alone vehicles that are flying around above their heads. However, Peng says it is safer for its flying car to be self-driving than to be driven by a human.
There are lots of flying cars in development now around the world and many of them actually fly, like Opener’s “BlackFly”, SkyDriver’s “SD-03’’and Klein Vision’s “AirCar” — which made a successful 35-minute test flight between two cities in Slovakia in 2021.

7 . The Music Educator Award, this year, went to Annie Ray, an orchestra(管弦乐队)director at Annandale High School.She was recognized for her efforts to make music accessible to all students, particularly those with disabilities.Ray got to attend the awards ceremony in Los Angeles and bring home a $10,000 prize.
Ray created the Crescendo Orchestra for students with severe intellectual and developmental disabilities, as well as a parent orchestra that teaches nearly 200 caregivers a year to play the same instrument as their child.Ray also works with a local charity to give damaged instruments a second life in her classroom.
The orchestra is about much more than just making music.The most important is to give students a chance to develop their cooperation skills, make mistakes and learn the art of refining something.Ray pushes her students to be brave, go outside their comfort zone and realize they have to learn how to make bad sounds before learning how to make good sounds.And they teach her a lot in return.” They changed my educational philosophy.I understand what it truly means to meet a student where they’re at and apply that elsewhere,” she said.
The warm reception on the ceremony was meaningful.Actually, not many people understand what exactly music educators do or how much their work matters.While her administration is supportive, that lack of understanding is a problem facing the profession in general.Another is resources.She says her school “desperately” needs new instruments.She will use some of her prize money to buy more.
Ray also plans to put some of the money towards an ongoing scholarship for students who want to pursue music when they graduate.She knows of several, those particularly interested in music, and aims to offer financial support needed to realize their musical dreams” It is hard but truly satisfying,” Ray said.“And there’s nothing else like it for them.”

8 . A therapy (治疗) client and I are working on an eating disorder and find it originated from a relationship break-up or perhaps being bullied in middle school. Such hurtful experiences led to not eating for a couple of weeks. Then comes a high praise from a friend that totally backfires. Maybe it’s an enthusiastic, “Wow, you look great!’’ In a flash, this praise excites an inner and often unconscious thought: “Oh, people care more about me if I lose weight. So many things feel out of control but I can control people’s affection by not eating.”
Often, very well-intentioned individuals offer praise out of a desire to uplift and connect. Such praise is often tied, directly or indirectly, to a person’s relationship with the standards of a specific group or institution. Sadly, such praise can easily reduce an individual’s dignity to their level in line with the group’s expectations rather than supporting their inherent (固有的) dignity and worth. So, what’s a better way?
One answer is to exit the game of “right and wrong” and enter a more life-giving focus on what needs are present. Returning to our example above, when you see that someone has lost weight and you want to give them a praise, just pause and take a deep breath. Simply ask, “How are you doing?” See them and hear them. Appreciate them as a person of limitless value. Know there may be much more to their inner world than meets the eye. Similarly, when you see someone’s success in school, appreciate the hard work they put into it. Ask with gentle curiosity, “How’s it been for you?” Listen with your full attention that in itself can be a rare gift in today’s hustle and bustle world.
By maintaining your concern and listening to the ways they want to be accompanied and supported — even when it might not be your first instinct — you can see them as a whole person, with complex feelings, very human needs, and inherent dignity.

| D．How Innocent Words can Be Harmful |
9 . Whether due to genuine concern for the environment or the widespread criticism of plastic among consumers, many companies have invested heavily in reducing their use of plastic packaging, which may indeed have a positive environmental impact. But another trend that’s grown out of the anti-plastic movement is a lot less positive: overpackaging. More and more brands have begun adding unnecessary paper packaging on top of plastic packaging in order to make their products look more environmentally friendly, without actually reducing plastic waste.
Unfortunately, there’s a very good reason companies are adopting this clearly problematic approach. Through a series of eight studies with more than 4,000 participants, we found that consumers will accept a product’s packaging as more environmentally friendly if it’s plastic with an additional layer of paper than if the product is visibly packaged in identical plastic packaging but without the paper. These perceptions (认知) in turn make consumers both more likely to buy a product, and willing to pay more for it.
Part of what makes this overpackaging trend particularly harmful is that it is much valued by consumers who reported engaging in more eco-friendly behaviors. They were more likely to view overpackaged products as environmentally friendly. As a result, the very consumers who are most interested in pushing companies to make sustainable choices are likely unintentionally encouraging the environmentally harmful practice of overpackaging.
The good news is, overpackaging isn’t the only way to signal sustainability and attract such consumers. In our studies, we found that instead of additional paper packaging, simply adding a minimal packaging sticker to plastic packaging could clarify the misperception that overpackaged products are more sustainable, Especially for products for which plastic is necessary to ensure safe transportation and lengthen shelf life, this kind of clear messaging can help reduce consumers, discrimination against the responsible use of plastic packaging.
Of course, minimal packaging stickers certainly should only be used if a brand has actually ensured that it is using the minimal possible packaging, ideally under the supervision of a trade organization or regulatory body that maintains clear, consistent standards.
