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.
According to the passage, birds singing, voiced meditation apps and the recording of the sounds of nature have the same effect on people’s mood.
4. Besides what is mentioned in the passage, what do you usually do to help you relax in your daily life? (In about 40 words)
3 . Most of us are actually terrible at giving gifts. About $70 billion worth of presents are returned every year in the U. S.
Stop trying to make your gifts so delightful.
How can we create a gift-giving plan that is as emotional as we desire? Humans love to feel connected. And one way we do that is by sharing interests with others. So if you want to learn how to give better gifts, put yourself in the recipient’s shoes and try to think of something you both share. Maybe it’s the love for a sport, drinking wine, or some other hobby.
A.So how do we get less terrible? |
B.Surprise is overrated — we’re happier to get what we ask for. |
C.So what's the most practical gift you can give that people might actually be grateful for? |
D.The long-term pleasure of the receiver may not be observed and therefore is discounted. |
E.Once you’ve found a shared interest, go and find a useful gift related to this interest. |
F.What recipients care about is how much value they’re going to get from the gift over a longer time period. |
G.Research has shown that givers are consumed by the moment of unwrapping a gift even more than the gift itself. |
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.”

5 . 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.
