1 . Working at a commercial bank in New York City in the mid-2010s, Anna Sacks sensed a lack of meaning in her life. She wanted to do something more fulfilling.
Some people seeking meaning might read a self-help book, or perhaps volunteer a few hours a week. Sacks packed up her life and moved to Connecticut for three months to participate in Adamah, a farming program that focuses on sustainable living and growing sustainable food. Returning to New York, Sacks carried with her a newfound purpose and a set of skills to turn her dreams into reality.
“One of the things that really stuck with me from Adamah was how little waste they produced and how they handled the waste they did have, mostly through composting,” she says. “And I just thought, ‘Why aren’t we doing that here? What is actually in all those bags and recycling bins at the roadsides?’”
The Adamah program opened Sacks’s eyes to the damage consumer culture is doing and the need to find solutions. So in 2016, she started working with a food rescue program, and in 2017, she found her true calling—what she calls “trash walking”.
During walks around her neighborhood, Sacks, 31, picked through trash to look for reusable items. Soon her trash walks expanded to include recycling bins in big companies. Surprisingly, she discovered really great stuff—like clothing and food—all of which she documents on Instagram and TikTok.
Under the name The Trash Walker, Sacks quickly gained popularity for her educational, funny, and surprising videos that highlight the problems with consumerism and share information about how to live a more sustainable lifestyle. “The root issue is overproduction, which leads to over-consumption, which leads to a large amount of waste,” she says.
Sacks is one of the most influential climate change activists on social media today. The lesson from her trash walking isn’t just that we need to produce less stuff. It’s that we need to stop throwing perfectly good items in the trash too.

3 . Too Much Information
Computer hackers, in order to get more secret information, constantly improve at breaking into cyberdefenses (网络防御系统) to steal valuable documents. So some researchers propose using an artificial-intelligence algorithm (算法) to hopelessly confuse them, once they break in, by hiding the real deal in a mountain of misleading documents and information.
The algorithm, called Word Embedding-based Fake Online Repository Generation Engine (WE-FORGE), creates decoys of patents under development. If hackers were after, say, the recipe for a new drug, they would have to find the relevant needle in a sea of false documents. This could mean checking each recipe in detail-and perhaps investing in a few dead-end ones. “The name of the game here is, ‘Make it harder, ” explains V. S Subrahmanian, its developer, Dartmouth College Cyber Security researcher. “Pain those stealing from you. ”
Subrahmanian says he tackled this project after reading that companies are unaware of new kinds of cyberattacks for an average of 312 days after they begin. “Hackers have almost a year to decamp with all our documents, patents and intellectual property, ”he says. “They have stolen almost everything. It’s not just the crown jewels-it’s the crown jewels, and the jewels of the cleaning lady, and the watch of the secretary!”
The documents produced by WE-FORGE could also act as hidden traps to confuse hackers, says Rachel Tobac, CEO of SocialProof Security. These documents might alert security when accessed. Companies have typically used human-created false copies for this strategy. But now the algorithm is able to do that for us.
The system produces convincing traps by searching through a document for key words. For each one it finds, it calculates a list of related concepts and replaces the original term with one chosen at random. The process can produce dozens of documents that contain no patent information but still look credible. Subrahmanian and his team asked computer science and chemistry graduates to evaluate real and false patents from their respective fields. And the humans found the WE-FORGE-created documents highly believable.
WE-FORGE might eventually expand its boundary. Both Subrahmanian and Tobac think this research will attract commercial interest. “I could definitely see an organization investing in this type of product, ” Tobac says. “If this creates believable decoys without releasing sensitive details within those traps, then I think you’ve got a huge with there. ”

4 . The Power of ”Like“
Like it or love it, social media is a major part of life. Teens spend more than half of their waking hours online. And most of what they do is read and respond to posts by friends and family. Clicking on a thumbs-up or a heart icon is an easy way to stay in touch.
Clicking ”like“ on a post can increase the number of people who see it. If other people have liked a post, new viewers will be more likely to like it too. Many social media sites share more of the higher-ranked posts.
According to recent studies, viewing one’s own posts with a lot of likes activates the reward system in their brains, especially for teens. Positive responses to teens’ own photos (in the form of many likes)tell them that their friends appreciate the material they’re posting.
A like is a social cue. Teens use it to learn how to navigate their social world. Clicking”like“ is a simple act that can have complex results. All tech users will be thoughtful about social media.
A.As a result, that popularity can feed on itself. |
B.It’s no surprise that feedback from peers affects how teens behave. |
C.Joining social media can give people a sense of being in the know. |
D.Their brains respond to those likes by turning on the reward center. |
E.For example, images related to alcohol may encourage teens to drink. |
F.And that can, inappropriately, make us feel less successful than them. |
G.But those ”likes“ can have power that goes beyond a simple connection. |
5 . Temptation (诱惑) is part of life. It is commonplace to find yourself in situations—for instance, choosing between a delicious dessert versus sticking to a diet, or playing video games instead of studying.
Unsurprisingly, research shows that people with greater self-control experience benefits such as success at school and work and greater satisfaction in their relationships. But there’s growing evidence that self-control can also come with various downsides.
The hidden costs of high self-control also extend beyond the social area to affect a person’s emotional life. For instance, consider the experience of regret. Research has shown that, when people reflect on their more distant past, they tend to regret having too much self-control rather than not having enough.
Even the positive beliefs that people hold about those who have high self-control, such as that they will perform better on group projects, can have negative effects.
Self-control is something nearly all of us try to be better at. But it’s also important to recognize that there can also be some costs to having limitless willpower.
A.Self-disciplined people are less likely to forgive others. |
B.People with higher self-control tend to enjoy better health in life. |
C.We can all benefit from understanding both sides of this research literature. |
D.Some of the costs of high self-control are social and reputational (有关声誉的). |
E.These ideas can create heightened expectations for the high self-control person. |
F.So enacting this self-control may actually lead you to feel less satisfaction down the road. |
G.During these times, you likely hope to make the ‘right’ decision that drives you towards your long-term goals. |
6 . Bingo has been a beloved game for generations, and for good reason.
Once you have your supplies, it’s time to invite your guests. You can invite your friends and family over for a fun night of bingo, or you can even host a virtual bingo party over video chat.
Once everyone has arrived, it’s time to start the game!
The caller is responsible for drawing the numbers and calling them out to the players. Players keep marking the numbers on their cards until someone achieves a winning pattern. There are various winning patterns in bingo, such as completing a row, column, or diagonal line, or achieving a specific shape or design on the bingo card.
The goal here is to have fun. While some organization is required, try not to tun it into a military operation. After all, bingo is the type of game that can bring people together and create a fun and exciting atmosphere.
A.Hand out the bingo cards to each player. |
B.You can ask your guests to bring their favourite bingo balls, cards and markers. |
C.It should be decided before the game starts, and known to all players. |
D.To host your own bingo party, you’ll need a few supplies. |
E.Instead of using traditional bingo numbers and letters, mix it up with different themes. |
F.If you’re hosting an in-person party, make sure to let your guests know what time to arrive. |
G.It’s a fun, exciting game and can be enjoyed by people of all ages. |

Nowadays, a lot of young people seem to spend much of their free time either watching television or playing computer games. Certainly, these things are entertaining, but they don’t contribute much to developing their brains. Many believe that reading books, and especially fiction, is a much more effective way of achieving this. The most obvious benefit we get from reading a good story is a growing vocabulary. We come across new words in reading and try to understand these words through context. Gradually, we become more confident with complex words. In addition, we improve in other areas such as speaking and writing just by reading regularly.
It has also been established that reading fiction is a good way of developing a good self-image. Non-readers or poor readers often have low opinions of themselves. Besides, they may perform poorly in other subjects because they cannot read and understand the material.
Most importantly, however, reading fiction helps us to develop our brains. The human brain can work well when we just do regular things, like driving or walking. However, learning expert Dr. Brian E. Walsh suggested that it can perform more effectively when an element of surprise is added, because this helps to build connections in the brain. In this respect, the positive effects of reading may be much stronger than previously thought.
Recent research has shown that the brain reacts more strongly to unpredictable than to predictable things. This may explain why people enjoy reading fiction, which generally contains lots of unpredictable things. Reading fiction enables us to experience fresh scenarios(情节) and identify with the people we are reading about. When we mentally create the scenes, the look of the characters, the smells, and the sounds in the book, we are exercising our brain. The brain is challenged. This is a positive thing because it will continue to grow and develop if properly stimulated. The more it is used, the better it becomes.
1. How does reading help us improve vocabulary?2. What are the problems for people who seldom read according to the passage?
3. Please decide which part is false in the following statement, then underline it and explain why.
> Reading fiction has more positive effects on our brain since fiction shows more predictable things in our daily life.
4. Apart from what are mentioned in the passage, what other benefit(s) have you gained from reading fiction?
9 . The need for clarity extends beyond how we communicate science to how we evaluate it. Who can really define stock phrases such as ‘a significant contribution to research’? Or understand what ‘high impact’ or ‘world-class’ mean? Scientists demand that institutions should be clear about their criteria and consider all scholarly outputs—preprints, code, data, peer review, teaching, mentoring and so on.
My view about the practices in research assessment is that most assessment guidelines permit sliding standards: instead of clearly defined terms, they give us feel-good slogans that lack any fixed meaning. Facing the problem will get us much of the way towards a solution.
Broad language increases room for misunderstanding. ‘High impact’ can be code for where research is published. Or it can mean the effect that research has had on its field, or on society locally or globally—often very different things. Yet confusion is the least of the problems. Words such as ‘world-class’ and ‘excellent’ allow assessors to vary comparisons depending on whose work they are assessing. Academia(学术界) cannot be a fair and reasonable system if standards change depending on whom we are evaluating. Unconscious bias(偏见) associated with factors such as a researcher’s gender, ethnic origin and social background helps the academic injustice continue. It was only with double-blind review of research proposals that women finally got fair access to the Hubble Space Telescope.
Many strategies exist to improve fairness in academia, but conceptual clarity is paramount. Being clear about how specific qualities are valued leads assessors to think critically about whether those qualities are truly being considered. Achieving that conceptual clarity requires discussion with faculties, staff and students: hours and hours of it. The University Medical Center Utrecht in the Netherlands, for example, held a series of conversations, each involving 20-60 researchers, and then spent another year revising its research assessment policies to recognize social impacts.
Frank conversations about what is valued in a particular context, or at a specific institution, are an essential first step in developing concrete recommendations. Although ambiguous(模棱两可的) terms, for instance ‘world-class’ and ‘significant’, are a barrier when performing assessments, university administrators have said that they rely on flexible language to make room to reward a variety of contributions. So it makes sense that more specific language in review and promotion must be able to accommodate varied outputs, outcomes and impacts of scholarly work.
Setting specific standards will be tough. It will be inviting to fall back on the misleading standards such as impact factors, or on ambiguous terms that can be agreed to by everyone but applied wisely by no one. It is too early to know what those standards will be or how much they will vary, but the right discussions are starting to happen. They must continue.

10 . For some it is the sound of a bouncing basketball. For others the clearing of a throat. For Dr. Jane Gregory the list includes pigeons, ticking clocks and the sound of popcorn being eaten. “I cried on the plane the other day because I couldn’t figure out the volume on my new headphones and so I couldn’t block out the sound of a guy sniffing,” she says. Gregory is among those who experience misophonia, a phenomenon in which particular sounds can prove unbearable, triggering(引起)emotions from anxiety and panic to shame and anger. Now in her book, Sounds Like Misophonia, the academic is on a mission to explore what’s behind it, and to help those affected cope.
Gregory, a clinical psychologist at the University of Oxford, suggests misophonia is far from being a simple sensitivity to sound. It can be fed by a complex interplay of factors, including a lower ability to filter out certain noises, the association of negative meanings with particular sounds, and the burden of feelings associated with an emotional response to them.
Yet, the phenomenon was largely unknown until the 2010s. In one study, researchers asked people with high and low traits of misophonia to listen out for a “trigger” sound in the presence of a masking sound. Both groups detected the trigger just as easily. “The person with misophonia had a more intense reaction, but only after they identified what the sound was,” adds Gregory. Those results, she says, suggest that people with misophonia are not inherently better at detecting particular sounds, such as a sniff or a rustle—rather they might be listening out for them more, or not be as good as others at tuning them out. This is a trait, Gregory speculates, that might have offered our ancestors an evolutionary advantage, such as helping them to detect hiding predators. Another implication of the research, Gregory says, is that it is not just the auditory features of the sounds that cause negative reactions but the meaning attached to them. An example would be a reaction to the jingling of a dog’s collar after being frightened by an aggressive dog.
Gregory hopes her book will support those too often told to ignore sounds. She says: “The emotional reaction is much more complex than just being annoyed... They feel trapped and helpless when they encounter these sounds. If you think it’s nothing, then you’re not experiencing what this person is experiencing.”
