1 . Evan Selinger, professor in RIT’s Department of Philosophy, has taken an interest in the ethics (伦理标准) of Al and the policy gaps that need to be filled in. Through a humanities viewpoint, Selinger asks the questions, “How can AI cause harm, and what can governments and companies creating Al programs do to address and manage it?” Answering them, he explained, requires an interdisciplinary approach.
“AI ethics go beyond technical fixes. Philosophers and other humanities experts are uniquely skilled to address the nuanced (微妙的) principles, value conflicts, and power dynamics. These skills aren’t just crucial for addressing current issues. We desperately need them to promote anticipatory (先行的) governance, ” said Selinger.
One example that illustrates how philosophy and humanities experts can help guide these new, rapidly growing technologies is Selinger’s work collaborating with a special AI project. “One of the skills I bring to the table is identifying core ethical issues in emerging technologies that haven’t been built or used by the public. We can take preventative steps to limit risk, including changing how the technology is designed, ”said Selinger.
Taking these preventative steps and regularly reassessing what risks need addressing is part of the ongoing journey in pursuit of creating responsible AI. Selinger explains that there isn’t a step-by-step approach for good governance. “AI ethics have core values and principles, but there’s endless disagreement about interpreting and applying them and creating meaningful accountability mechanisms, ” said Selinger. “Some people are rightly worried that AI can become integrated into ‘ethics washing’-weak checklists, flowery mission statements, and empty rhetoric that covers over abuses of power. Fortunately, I’ve had great conversations about this issue, including with some experts, on why it is important to consider a range of positions. ”
Some of Selinger’s recent research has focused on the back-end issues with developing AI, such as the human impact that comes with testing AI chatbots before they’re released to the public. Other issues focus on policy, such as what to do about the dangers posed by facial recognition and other automated surveillance(监视) approaches.
Selinger is making sure his students are informed about the ongoing industry conversations on AI ethics and responsible AI. “Students are going to be future tech leaders. Now is the time to help them think about what goals their companies should have and the costs of minimizing ethical concerns. Beyond social costs, downplaying ethics can negatively impact corporate culture and hiring, ” said Selinger. “To attract top talent, you need to consider whether your company matches their interests and hopes for the future. ”

In a fast-paced world, where stress and mental tiredness seem commonplace, we’re constantly looking for new ways to unwind. People may carry out a variety of activities to help them relax. But what about the birdsongs or other nature sounds? Could they also help people to let go of the tensions of modern life?
According to a study by King’s College London in 2022, seeing or hearing birds could help to boost the mental wellbeing of people. Taking a trip to places rich in birdlife like parks, forests and canals and encountering birds singing to each other in the trees could even help to treat some mental health conditions. And it’s not just birds that could have a curative effect on our moods. Another study conducted by the National Trust compared the effects of woodland sounds with voiced meditation (冥想) apps. The study found listening to birdsong as well as other woodland sounds like leaves crunching underfoot or the gentle flow of a stream boosted feelings of relaxation 30% more than the apps do. Other sounds which may help to cool people down are waves lapping on the shore, gentle wind, and light rainfall.
However, not all of us live in rural surroundings, and depending on where we live, a trip to the countryside to see birds may not be an option. But could the nature sounds that originate there still help you? According to research by California Polytechnic State University, even a recording of the sounds of birds had a profound effect on people’s mood, while other studies saw people listening to soundscapes of the coast and forests with similar outcomes to their wellbeing.
So, wherever you live, you can access the wonderful sounds of birds and nature during a stroll through a wood or via some headphones. And maybe listening to the chirps, trills, warbles and whistles of some birds could help you to relax after a long, hard day.
1. What did the study by King’s College London in 2022 find?2. How did the National Trust conduct the study?
3. Please decide which part is false in the following statement, then underline it and explain why.

3 . As this year draws to a close, I still remember the fear I felt on a bright Saturday morning in late September, at a five-kilometer race in Clarkston, Georgia, as I waited for my 11-year-old son at the finish line.
I knew he could run a 5k in about 30 minutes. When I didn't see him at the 35-minute mark, I began to wonder what had gone wrong. Had he gotten lost? Was he hit by a car? About an hour earlier, when we drove into town, my son noticed an insect on my car. It was bright green, no longer than a fingernail. And it was friendly. This little green thing hopped onto my son's finger, where it stayed for a long, long time. It stayed so long that we eventually gave it a name: Little Friend.
A few minutes before the race, Little Friend jumped off my son’s hand and landed on the sidewalk. But pedestrian traffic was heavy and unpredictable. Little Friend was in danger. So my son knelt and reached out his hand. Little Friend came back.
The race was about to start, and the tiny green insect was in for a wild ride. My son would run fast, and the race would be long, and his arms would swing, and Little Friend would eventually be shaken off.
“You will lose Little Friend,” I told him.
My son nodded, treating the moment with appropriate seriousness.
The race began, and I lost sight of him.
The excitement at the finish line gave way to anxiety when my son did not show up.
I kept asking people if they'd seen him. No one had. And beyond the 40-minute mark, I was in a panic.
But there he was, thank goodness, just ahead of the 45-minute mark.
And there was Little Friend, riding on the upper crook of his right thumb like a very small captain on a very tall ship.
My predictions had been wrong. My son had not run fast, and he had not lost Little Friend. And these two facts seemed somehow related. He blamed a cold he was getting over. I suspected it was more than that, but I didn’t question him too much about it.
We walked back to the car, smiling, and found some bushes in the parking lot that seemed like a good place for my son to drop off Little Friend.
“Be free,” my son said, and gently put it in the bushes.
My son knew the truth. Sometimes life gives you something beautiful, a fragile, short-lived treasure in your hand. There is no need to rush ahead. Treat it gently. Enjoy each moment. Hold on while you can.
One day my son will leave too, running off on his own adventure.

4 . While some allergies (过敏症) disappear over time or with treatment, others last a lifetime. For decades, scientists have been searching for the source of these lifetime allergies.
Recently, researchers found that memory B cells may be involved. These cells produce a different class of antibodies known as IgG, which ward off viral infections. But no one had identified exactly which of those cells were recalling allergens or how they switched to making the IgE antibodies responsible for allergies. To uncover the mysterious cells, two research teams took a deep dive into the immune (免疫的) cells of people with allergies and some without.
Immunologist Joshua Koenig and colleagues examined more than 90, 000 memory B cells from six people with birch allergies, four people allergic to dust mites and five people with no allergies. Using a technique called RNA sequencing, the team identified specific memory B cells, which they named MBC2s that make antibodies and proteins associated with the immune response that causes allergies.
In another experiment, Koenig and colleagues used a peanut protein to go fishing for memory B cells from people with peanut allergies. The team pulled out the same type of cells found in people with birch and dust mite allergies. In people with peanut allergies, those cells increased in number and produced IgE antibodies as the people started treatment to desensitize them to peanut allergens.
Another group led by Maria Curotto de Lafaille, an immunologist at the Icahn School of Medicine at Mount Sinai in New York City, also found that similar cells were more plentiful in 58 children allergic to peanuts than in 13 kids without allergies. The team found that the cells are ready to switch from making protective IgG antibodies to allergy-causing IgE antibodies. Even before the switch, the cells were making RNA for IgE but didn’t produce the protein. Making that RNA enables the cells to switch the type of antibodies they make when they encounter allergens. The signal to switch partially depends on a protein called JAK, the group discovered. “Stopping JAK from sending the signal could help prevent the memory cells from switching to IgE production,” Lafaille says. She also predicts that allergists may be able to examine aspects of these memory cells to forecast whether a patient's allergy is likely to last or disappear with time or treatment.
“Knowing which population of cells store allergies in long-term memory may eventually help scientists identify other ways to kill the allergy cells,” says Cecilia Berin, an immunologist at Northwestern University Feinberg School of Medicine. “You could potentially get rid of not only your peanut allergy but also all of your allergies.”

6 . Sarah came running in. “Look what I found.” Over the top of the paper I was reading came a crispy long object that caused me to jump. It was a snake skin that had been shed by one of our many garden snakes.
“Isn’t it beautiful?” said my wide-eyed seven-year-old.
I stared at the organic wrapper and thought to myself that it really wasn’t that beautiful, but I have learned never to appear uninterested with children. They see only good quality and excellence in the world until educated otherwise.
“Why does it do this?” Sarah asked.
“Snakes shed their skin because they need to renew themselves,” I explained. “Why do they need to renew themselves?“ Sarah asked.
I suddenly remembered an article on this page many years ago where the writer was expressing her concept of renewal. She used layers of paper over a wall to describe how we hide our original selves, and said that by peeling away those layers one by one, we see the original beneath. “We often need to shed our skins and those coatings that we cover ourselves with,” I said to my now absorbed daughter. “We outgrow some things and find other ones unwanted or unnecessary. This snake no longer needs this skin. It is probably too crinkly (起皱的) for him, and he probably doesn’t think he looks as smart in it as he once did.”
Sarah was getting the point. As we talked, I knew that she began to understand, although slightly, that renewal is part of progress; that we need to take a good look at ourselves, our rooms, schoolwork and creativity, and see what we need to keep and what we need to cast off. I was careful to point out that this is a natural consequence of their growth.
“I see, Dad,” said Sarah and jumped off my lap and ran off.
I hoped she would remember this. That often, in order to find our real selves underneath the layers of community and culture with which we cover ourselves year after year, we need to start examining these layers. We need to gently peel some away, as we recognize them to be worthless or unnecessary; or at best, store the ones thrown away as mementoes of our promotion to a better vitality or spirit.
1. Sarah learned from her father that renewal is .| A．to recover the layers inside | B．a natural part of getting mature |
| C．to review what has been done | D．the process of finding the unwanted |
| A．dislikes the snake skin at all | B．shows concern for nature and culture |
| C．can grasp the chance to educate children | D．often encourages his daughter to raise questions |
| A．we should renew ourselves to get improved | B．snakes cast off the layers to look smarter |
| C．snakes shed their skins to renew themselves | D．we should explore our original nature underneath |
7 . Jim Glaub and his wife just moved into their new Manhattan apartment on 22nd Street when the previous houseowner said something curious: “Just so you know, there’s this thing where letters addressed to Santa come to the apartment. It has been coming for years and no one knows why. But it’s not that big a deal. ”
Then in the months leading to Christmas, letters from kids or parents to Santa came flooding in, asking for gifts they could not otherwise afford. Glaub and his wife responded to as many as they could, writing notes, even buying gifts. But they could do only so much.
Glaub, of course, is not Santa. He runs a marketing company. But one night, when the couple threw a Christmas party, a solution appeared. The guests noticed the hundreds of letters they’d yet to act upon piled in the corner of their dining room and asked about them.
“I told them the story, ” Glaub said. His guests were very interested. “A lot of people were like, ‘I’ll take a letter. I’ll fulfill it. ”
And so was born Miracle on 22nd Street, a community-based volunteer organization that responds to children’s letters to Santa with season’s greetings and gifts. Working with other nonprofits that help those in need, Glaub invited families from around the country to go online and request gifts for their children. Meanwhile, donors can sign up to buy gifts for a child or family, accompanied by a signed note.
Letters typically request popular items, such as toys, coats, a doll for little kids, makeup and bikes for older ones. One child suffering back pain from sleeping on the living room couch in a crowded household asked for a bed.
Some letters are heartbreaking. One child wrote: “Dear Santa, for Christmas, I want my brother to get better. My younger brother has a hard time walking and has to use his wheelchair. I wish he could play like me.”
That’s a tough ask. But Glaub did send the children gift cards and a kind note.
Last year, Glaub and the organization helped more than 800 families. One beneficiary wrote: “…you gave my babies a reason to smile and enjoy their Christmas after everything we’ve been through. All I wanted was to see them happy and I got just what I wanted.”
Glaub no longer tries to figure out why the letters come to the apartment. Putting in the long hours to help the families is what it’s all about for him.

If you’ve recently taken a flight from a major UK airport, then you may have noticed that more people are protesting air travel expansion and encouraging people to fly less. This is part of a larger environmental movement sweeping across Europe. Known as Flygskam or “flight-shaming”, the movement is encouraging people to stop taking flights as a means of transport and use more environmentally friendly transportation where they can.
The aviation (航空) currently accounts for about 2% of global emissions (排放) and is one of the fastest-growing polluters. Even worse, unlike most other sources of pollution, air travel results in pollutants released high up in the atmosphere.
Earlier this year, the UK government promised to reduce the UK’s emissions to “net zero” by 2050. However, according to projections from some researchers, emissions from the aviation could more than double by then even if planes become substantially more fuel-efficient. So, it’s unclear whether flying will be included in the UK’s target.
It’s hard to say exactly how big the movement is becoming, but Flygskam has become popular in social media. The number of Swedes taking the train for domestic journeys has risen by 8% this year as plane journeys inside the country have fallen. Clearly, Flygskam is having a measurable impact on people’s transport choices. Some people, however, have been critical of the movement because they say that it places blame or feelings of embarrassment onto the passengers when it is really the airlines and industries associated with it who should feel guilty for the impact that they are having on the planet.
1. What is Flygskam?2. How does flying influence the environment?
3. Please decide which part is false in the following statement, then underline it and explain why.
Flygskam has attracted social attention and some people have already participated in this campaign, so it is widely accepted.
4. Besides what is mentioned in the passage, what do you think of the movement of Flygskam? (In about 40 words)
Alle Pierce knows how to plan a holiday. A few months ahead of time, she constructs a spreadsheet of what she wants to do and see. She examines the menus of restaurants she is planning to visit. She uses a picture of the destination as her phone’s locked screen image and downloads a countdown app. “What’s so exciting about a trip is the anticipation before it,” says Pierce, founder of a luxury travel company.
Experts stay she is right. Recent studies suggest that hoping for something boosts your mood and lowers your stress. “Imagining good things ahead of us can increase motivation, optimism and patience,” says Simon Rego, a psychologist from New York.
Of course we can’t just book a flight every time we need a little cheering up or feel low. But there are ways to incorporate the power of anticipation into your everyday life.
Get excited about little things. Write down one thing you’re excited for tomorrow. Maybe it’s a new book, or a package you’re expecting. The collection of these mini thrills means you will still gain the benefits of looking forward to something. Plus, with the nearer stuff, there’s more of a sense that it’s going to happen for sure.
Remember that anxiety and anticipation can coexist. “The dark side of positive anticipation is anticipatory anxiety. Anxiety and excitement are sister emotions,” says Christian Waugh, a psychology professor from North Carolina. But it is harmful only when you just focus on the anxiety part and ignore the excitement part. The key is acknowledging the happy, positive aspect of what you are doing, along with the nervous feelings. When you consider anxious things as exciting, it actually makes you feel better about them.
Connect with your future self. Research has shown feeling as if you are on a path to your future self can have a positive effect on your well-being by getting you out of short-term thinking. Thinking ahead may help you prioritize your goal and move toward it. As you start seeing progress, you will look forward to doing the things that get you closer to your future self.
In short, to enjoy life more, embrace anticipation. It’s worth waiting for.
1. What makes a trip exciting according to Alle Pierce?2. How does hoping for something benefit us?
3. Please decide which part is false in the following statement, then underline it and explain why.
According to the research, connecting with your future self can have a negative effect on your well-being.
4. Please give an example to show how you can incorporate the power of anticipation into your daily life. (In about 40 words)
10 . An AI model can be used to detect stress in office workers based on how they use their mouse and keyboard. A new study suggests that a machine-learning model using these two elements was more accurate at detecting stress in people than a model that tracked their heart-rate data.
“We saw that the models that just used the mouse and keyboard data performed better than the models that had the heart-rate data in it,” says Mart Naegelin. a Ph. D. student at the Swiss Federal Institute of Technology, and one of the study’s authors.
Naegelin and her fellow researchers used machine-learning models to analyze data on keyboard-typing activity, mouse movements and heart-rate data. They also studied the data of a combination of two or all three of these elements to determine which performed best in terms of measuring stress. They found that the model trained on mouse and keyboard data performed better than the model that used mouse, keyboard and heart rates. Of the single-modality (形态) models, the heart-rate data performed the worst. “The test was conducted in an environment that simulated an office environment, so the results still need to be confirmed in real-life scenarios (情况),” Naegelin says.
In the experiment, participants were divided into three groups. A control group carried out assigned tasks, such as planning meetings and collecting data, with no additional work. A second group at times answered questions from managers in person in a mock interview scenario while completing other assigned tasks. And members of a third group were, at certain points, interrupted with additional questions sent through an online chat on top of tasks assigned to other groups. At regular intervals during the experiment, participants were asked to rate their stress levels through a computer questionnaire.
Researchers learned that workers made longer, less accurate movements with their mouse, as well as more typing errors, when they were stressed. Shorter, more direct movements with the mouse were tied to lower stress levels. The study didn’t focus on why increased levels of stress are thought to affect muscle activity.
The researchers say they believe a stress-detection system that logs keyboard and mouse movements might be beneficial as a self-help tool for employees alongside other initiatives to improve workplace mental health. But employee participation would need to be optional and based on informed consent (同意), and companies would need to commit to protecting user privacy.
It remains to be seen how this technology will evolve and be adopted in practice, but the potential for AI to contribute positively to employee well-being is an appealing avenue for future exploration.
