1 . Researchers at the University of Rochester have recently discovered elusive cells in the eye that could provide insights into how humans perceive color. Read the following passage and answer the questions that follow.
Researchers using adaptive optics have identified rare retinal ganglion cells (RGCs) that could help explain the mechanism behind human color perception. These cells, previously unknown, may hold the key to understanding how the eye’s cone photoreceptors work together to interpret the world in a rainbow of hues.
The retina, the light-sensitive tissue lining the back of the eye, contains three types of cones that are sensitive to different wavelengths of light: short, medium, and long. These cones detect color and transmit their signals to the brain through retinal ganglion cells. While the basic function of these cones has been understood for decades, the precise way they interact to create our perception of color has remained a mystery.
In the past, scientists had mapped the “cardinal directions” of color detection, but they suspected that there might be more to the story. They hypothesized that while most RGCs follow these cardinal directions, a small number of noncardinal RGCs might work in tandem to create more complex color perceptions.
The new research suggests that these elusive noncardinal RGCs, found in the fovea — the central, most sensitive part of the retina — could be the missing link in our understanding of color vision. However, much remains unknown about these cells and how they function.
“We don’t really know anything for certain yet about these cells other than that they exist,” says Sara Patterson, a postdoctoral researcher at the University of Rochester Center for Visual Science who led the study. “There’s so much more that we have to learn about how their response properties operate, but they’re a compelling option as a missing link in how our retina processes color.”

Title: A Day of Unexpected Adventures
One sunny afternoon, Lily, a curious and adventurous girl, decided to explore the mysterious old forest near her house. She packed a small backpack with some snacks and a map, and set out on her adventure.
As she walked through the dense trees, she heard rustling leaves and the chirping of birds. The air was filled with the scent of fresh earth and wildflowers. Suddenly, a bright flash of color caught her eye. It was a rare butterfly, its wings shimmering with iridescent blues and greens. Lily slowly followed the butterfly, her heart filled with excitement.
As she followed the butterfly deeper into the forest, Lily realized that she had lost sight of it. She looked around, trying to orient herself with the map, but the dense foliage made it difficult to navigate. Suddenly, she heard a strange sound coming from a nearby bush. Curious, she cautiously approached and peeked inside. To her surprise, a small fox was looking back at her with big, round eyes.
The fox seemed friendly, and Lily slowly reached out to pet it. The fox nuzzled her hand and then led her through the forest, as if guiding her to somewhere. Lily followed eagerly, her curiosity piqued. They passed through a clearing filled with wildflowers and came to a small stream. The water was clear and sparkled in the sunlight. Lily knelt down to take a sip, and the fox seemed to smile at her, its tail wagging happily.

6 . Gardening for Biodiversity: Big or Small, Every Garden Counts
Gardening is not just about planting flowers and vegetables. It’s also a powerful tool for enhancing biodiversity. A recent report emphasizes that even the smallest of gardens, such as a window box, can make a significant difference in halting the decline of wildlife.
In the UK, overall wildlife numbers have declined by 13% since the 1970s, with some species showing a decline of up to 41%. Fifteen percent of species are currently considered threatened. However, the report from Garden Organic suggests that ordinary gardeners, through their daily activities, could have a profound impact on reversing this trend.
One of the key recommendations is to plant a diversity of flowers. Flowering plants, such as sedum, thrive on roofs and balconies, attracting insects and birds. Herbs like thyme and rosemary not only provide food for humans but also serve as nectar sources for pollinators. Nasturtiums, while attracting bees, also bring color to the garden.
Moreover, gardeners can create habitats for wildlife. For instance, old tin cans filled with hollow stems can be turned into insect or bee hotels, providing shelter for these small creatures. Compact vegetables, such as spinach and tomatoes, can be grown even on balconies, not only contributing to one’s daily intake of nutrients but also adding greenery to urban spaces.
Climbing plants like honeysuckle can act as natural screens, providing shade and reducing wind speed on balconies. They also add to the aesthetic appeal of the garden.
In summary, every gardener, regardless of the size of their garden, has the power to contribute to biodiversity conservation. Simple actions like planting a variety of flowers, growing vegetables, and creating habitats for wildlife can make a significant difference. As report author Dr Bruce Pearce, Garden Organic’s director of horticultural science, says, bringing biodiversity in the garden is easier the bigger the plot you have; but you can do your bit to tackle the “bleak” biodiversity situation even if all you have is a window box.

7 . The Boxing Academy in Hackney, east London, is not just a regular school. Here, every student spends 40 minutes a day in the boxing ring, alongside traditional subjects like maths and science. The school’s unique approach aims to teach young people life skills through the discipline and focus of boxing.
Many of the students at The Boxing Academy have had difficult experiences in their lives and have been excluded from mainstream schools due to violence. However, the school’s headteacher, Anna Cain, insists that boxing is not about aggression but about teaching students how to manage their emotions and anger. She believes that the sport can help young people develop self-reliance and learn to control their temper.
The walls of the school are adorned with posters of famous boxers like Tyson Fury, and the unofficial school motto is a quote from Mike Tyson: “Everyone has a plan until they get punched in the face.” This quote serves as a reminder to the students that life is unpredictable and they need to be prepared for whatever comes their way.
Ex-pupils of The Boxing Academy attest to the positive impact the school has had on their lives. They say that the boxing training has helped them become calmer and more focused, and has taught them valuable life lessons about managing anger and emotions.

9 . My Ph.D. (博士学位) adviser had encouraged me to take a vacation. So I was sitting at an airport restaurant, when I received the email. It informed me I had failed my qualifying exam on my second attempt, which meant dismissal from the program. I knew things hadn’t gone perfectly. But I was still shocked. How was it possible that one exam could erase all my other successes and define me as unfit to be a scientist?
I wasn’t sure what to expect when I started my Ph.D. program. As a first-generation college graduate, I didn’t have family members who could tell me what it was like. I had put in a lot of effort, but it didn’t seem to pay off during my first year.
I ended that year with increased confidence, eager to put my newfound knowledge into action. But my confidence took a plunge shortly thereafter, when I made my first attempt at the qualifying exam. I had never taken a presentation before, so the experience was terrifying. I stood in front of my exam committee.
Once it was over, my committee told me I’d conditionally passed, which meant I’d have one more chance. For the next 2 months, I did everything in my power to prepare. When the exam was over, I left the room feeling a mix of fear and relief. But those feelings changed to frustration the next day, after I learned I’d failed.
But soon, things started to change. After a series of meetings, faculty members (全体教师) decided to do away with the qualifying exam structure I’d struggled with. Students would be asked questions, so that faculty could learn more about their knowledge and provide constructive feedback.
As a result, I’m now back to working on the program. I try to stay focused on becoming the best scientist I can be. In the end, I am much more than that one-hour exam.
