Hsiao's fencing journey began at a summer camp before her eighth grade year. Despite spending long hours sweating in fencing gear and competing against more experienced opponents, which left her tired and frustrated, her time at camp awakened her interest in the sport, which she later pursued.

In high school, Hsiao found a welcoming community of fencers and coaches, some of whom also went to participate in February's Junior Olympics. She developed and refined her skills with the foil, the smallest and lightest fencing weapon targeting the body.

In her senior year, Hsiao suffered a devastating ACL tear (前交叉韧带撕裂), which put her fencing career in danger. "I thought I would never get back into fencing," she said. After surgery and nine months of punishing physical therapy two to three times a week, Hsiao began fencing again. Regarding the changes to her fencing after the injury, Hsiao noted, "I've always been a more defensive fencer so my fencing hasn't changed too much after my injury. I do have to think more about getting my back leg under me while I fence."

Beyond the physical alterations to her style, Hsiao spoke on the mental adjustments for high-level competitions. She emphasized the importance of positive thinking and mental preparation, saying, "If you think you're going to do badly, it does have an impact on how you fence." Moreover, from recent meets, including the Junior Olympics, she learned to "trust instincts (直觉) and avoid overthinking during matches."

Hsiao also revealed the life lessons fencing has taught her, saying, "Not giving up is key and losing is one of the best ways to learn." Her next goal in fencing is to continue competing at a national level and earn a rating from the United States Fencing Association through tournament victories.

Every AI system we create functions as a mirror, reflecting our values, priorities, and assumptions. When facial recognition technology struggles to identify darker skin tones, this is not a breakdown; it is a reflection of the assumptions and perspectives inserted in the data it was trained on.

In 2018, Amazon abandoned an AI-powered hiring tool after discovering it held prejudice against female candidates. The AI wasn't programmed to discriminate, but it was trained on historical hiring data that favored men, and it learned to copy those patterns. Similarly, research from UC Berkeley found that mortgage (抵押贷款) approval methods often less favorable terms to Black and Hispanic applicants, reinforcing longstanding inequalities in lending.

The use of AI systems in law enforcement, healthcare, and education reveals similar patterns. Predictive policing tools tend to focus on certain communities because they are trained on historical crime data. Algorithms (算法) in healthcare may be more likely to give wrong information to patients belonging to certain groups. Automated grading systems in schools have sometimes been shown to favor students from wealthier economic backgrounds over others when the quality of the work is the same. In all these cases, AI isn't creating new biases (偏见), but it is reflecting existing ones.

This mirroring effect manifests a significant opportunity for self-examination. As AI continues to develop, we must ask ourselves how we as individuals want to shape its role in society. This isn't just about improving algorithms, but ensuring that AI is deployed responsibly. Some organizations are already taking steps in this direction.

As we continue to integrate AI into our lives, we must recognize that these systems don't just predict our behavior; they reflect our character. That reflection allows us to make better, more principled choices, but only if we're willing to look closely and take responsibility for what we see.

We already knew that omega-3s — "good" fats found in seeds, nuts and some fish — can boost our immunity (免疫力), heart health and brain function. They have also been linked to changes in epigenetic (表观遗传的) markers — chemical tags on DNA that control the activity of genes and, in turn, how cells behave. This implies that omega-3s reduce the pace of biological aging, often defined as a measure of how quickly someone's body is worsening compared with other people.

Dr. Heike Bischoff-Ferrari and her team at the University of Zurich wanted to explore omega-3's effect on aging further, as well as find out how it may work alongside vitamin D supplements and exercise. The team divided 777 people in Switzerland, aged 70 to 91, into eight groups. On top of their existing lifestyle habits, each group was told to take varying combinations of a daily 1-gram dose of omega-3, placebo (安慰剂) pills and 2,000 international units of vitamin D. In addition, some groups were instructed to do 30 minutes of strength training three times a week.

At the start of the es study, the researchers tracked biological aging using epigenetic clocks which analyze age-related DNA markers in blood samples. These markers typically decline with age, damaging cell function.

After three years, the scientists found that the participants who took omega-3 only had aged by around 3 months less, on average, than those who were only given placebo pills. They took into account factors that could affect the results, such as the participants' actual age and sex. What's more, those who took omega-3 along with vitamin D and did strength training aged even less, compared with people who didn't introduce any of these habits. "The effect was somewhat more pronounced, almost four months of rejuvenation (恢复青春)," says Bischoff-Ferrari.

"These effects may seem small, but could be important for some," says Richard Siow at King's College London. "For an older person, in about three months, there could be a lot of age-related decline going on, so this becomes more significant," he says.

For me, it's the unhealthy foods like chocolate that put a smile on my face—well, I do have a sweet tooth! It might seem obvious that's bad for our waistline, usually makes us happy.. But dietitians tell us that eating bad food for a long time not only leads to many health problems, but it can also affect our mental state and cause depression.

The link between our mind and food has been looked at by scientists. They've recently found that it's the bacteria (细菌) in our body that affect our mood. Researchers in Canada have found that certain "good" bacteria help reduce anxiety in mice..

Many food products are claiming to be high in such "good" bacteria and some of the best types are homemade food like yogurt.. Maybe I should change my diet to brighten me up! Doctor Michael Mosley would agree. He's been looking into this for the BBC and says the best food to cheer us up is in a "Mediterranean diet"; olive oil, whole grains, lots of fruits and vegetables. Sugar: terrible for you!

So maybe it's time to lay off the fatty and sugary things., even if the science behind it is complex. It's not rocket science but this is further evidence for the saying "we are what we eat". There are other factors that can change our mood but it seems we have some ability to improve how we feel by controlling what we put on our plate.
 

A. I don't want to give it a try.

B. Eating healthily may seem simple.

C. We are indeed determined by the we eat.

D. This really makes me think twice about what I eat.

E. Food also gives us energy and minerals our body needs.

F. Most of us get this feeling when we use food as a quick pick-me-up.

G. For us humans, this means food with "good" bacteria can improve how we feel.

Then, Mikey began to cry. "Play car-car, Mikey," Hill whispered, hoping that might make him3. The front seat was a long bench, and without a seat belt, Mikey had the4to slide over to the driver's seat. Mikey5 the steering wheel (方向盘) suddenly and6, his foot knocked the gear shift (换挡杆). The car, parked on a slope (斜坡), began to roll backward.

The English Club

The first time I saw Lily, my new classmate, a wave of disappointment washed over me. Her chaotic hair stuck out in all directions as if going g against gravity, the thick-rimmed glasses made her eyes look extremely big, and her clothes — loose blouses and long skirts — seemed like they were scratched straight out of a recycling store.

She was so different from the trendy girls in our class. I leaned towards my best friend, whispering, "She looks like a total bookworm. Probably she has no social skills." Of course, it was exactly what her appearance indicated.

For weeks, I secretly made fun of Lily. During lunch breaks, while the rest of us gathered around tables, chatting and sharing gossip (闲话), she would sit alone in the corner, her nose buried in a thick novel. Every time I caught a glimpse of her, I'd roll my eyes and exchange dismissive looks with my friends. But there were moments when I couldn't help but notice how effortlessly she answered teachers' questions in class. Her responses were so fluent and confident that it sent a small flow of unease through me. Still, I pushed those thoughts aside, determined to hold onto my previous thoughts.

One day, our teacher announced the group project on environmental protection and when I found out I was paired with Lily, a sense of fear settled in my stomach. I imagined long, painful meetings filled with her awkward silences. But as we sat down to discuss our plan, I was immediately taken aback.

Lily pulled out a stack of neatly organized research papers, her eyes sparkling with excitement as she outlined her ideas. "We could organize a community clean-up day," she said, her voice brimming with enthusiasm. "And create interactive educational posters to make recycling fun!" I listened, shocked, as she spoke with such passion and clarity. For the first time, I felt a bit of doubt about my initial judgment.

As we worked together, that doubt grew into an overall realization.

The day of the presentation arrived, and I watched in awe as Lily took the stage.
