But then, during English class, something unexpected happened. The teacher asked us to introduce ourselves by sharing a short story. My heart raced and my voice shook as I spoke about how my grandmother taught me to recite (朗诵)English poems under the stars in our backyard. I remembered the smell of jasmine in the summer air and the way my grandmother's voice carried a quiet strength. To my surprise, the class listened in silence, and when I finished, a soft round of applause (掌声)came from several students. For the first time that day, I felt seen.

After class, a girl named Lily came up to me. "I love poetry, too," she said with a warm smile. We talked about our favorite writers and the comfort that words can bring. She invited me to join the school's English club. The following weeks were filled with new experiences: reading aloud with confidence, preparing small plays that made us laugh, even writing our own poems and sharing them. For the first time since moving, I felt that English was not just a subject, but a bridge that connected me to others and gave me courage.

By the end of the term, I was no longer the quiet student in the back row. Standing on stage, reciting a poem with my new friends, I realized that starting over didn't mean losing myself — it meant discovering a new side of me, one that was braver, stronger, and ready to belong.

Yet marginalia are hardly a modern invention. From Leonardo da Vinci to modern writers, generations of readers have long left their thoughts in the margins. Such notes often provide valuable insights for later readers and occasionally reshape the understanding of the text. In recent years, bestselling novelist Ann Patchett released a special edition with notes of her novel Tom Lake to raise money for bookstores, showing how marginalia can generate cultural and financial value.

Scientists have also examined the phenomenon scientifically. A study in Frontiers in Psychology recorded brain activity and found that writing by hand uses more parts of the brain than typing. This suggests that the physical act of writing, including marginalia, deepens memory and comprehension. Maryanne Wolf at UCLA further argued that making notes enables readers to go beyond the author's ideas and discover their own understanding.

In education, marginalia also plays a role. Turkish professor Demet Yayli observed that taking notes encourages deep reading, helps students clearly express their views, and strengthens their learner autonomy. With greater autonomy, students are able to make decisions in learning and take responsibility for their progress, rather than wait for directions. Although note styles may appear unusual — underlining every line of a favorite character or marking romantic passages — experts agree that as long as the practice aids comprehension, any style is acceptable. Writing in the margins, far from being harmful, can personalize texts and enrich intellectual engagement.

In Amazonas alone, about 15 million hectares of forest have thus been protected. The costs are low, but the benefits are great: Fish numbers have gone up again, and animals such as giant otters, manatees, and Amazon river turtles have also increased. These achievements highlight the special strengths of local people. Permanently present in these landscapes, they have the strongest interest and ability to keep resources safe, becoming the "unsung heroes" of conservation. The model also shows a good mix of scientific knowledge and traditional practice: while protecting biodiversity (生物多样性), it also increases family income through sustainable harvests.

However, there are challenges. At present, all the costs are dealt with by the volunteer watch groups themselves. Depending only on unpaid work cannot last long. To solve this, systems such as Payments for Environmental Services (PES) should be used so that communities can be properly paid.

The researchers urge greater recognition and financial support from governments and civil society. Supporting community-based conservation is not only an ecological necessity but also a matter of social justice (公平). By empowering those already engaged in frontline conservation, society can safeguard biodiversity, strengthen local economies, and ensure a better future for the next generations.

The English language is spoken by millions of people worldwide and is famous for its many curiosities. From unusual spelling rules to surprising vocabulary, it offers learners both fun and challenges.

Hundreds of new words are added to dictionaries every year. In 2020 alone, more than 500 were included in Merriam-Webster. This shows that language grows together with them.

Letters also play curious roles. "E" is by far the most common, appearing in about 11% of all words. It occurs in "the," the most used word, and in verbs like "be." With so many appearances, it is naturally the most typed letter on keyboards.

Pronunciation brings even greater challenges. The combination "ough," for example, can be pronounced in ten different ways. In one sentence——"A rough-coated, dough-faced, thoughtful ploughman strode through the streets of Scarborough"——all of them appear. These irregularities remind learners that English spelling has never been fully unified.

Culture adds more surprises. The United States, for instance, has never declared English its official national language, even though it dominates daily life.This shows that a language's influence depends more on practice than on law.

English continues to evolve. Dictionaries expand every year, old words gain new meanings, and learners everywhere adapt to its changes.

B. Such a fact may surprise many language learners.

C. This mix of rules and exceptions puzzles learners.

G. As a result, English stays one of the most active languages in history.

Some coworkers told me, "You know what? I just feel more at3 when I watch these little guys." Before long, the caterpillars formed bright green chrysalises (蛹). At first I thought they had4, but then I saw movement — the butterflies were coming out. It was5.

That gave me an idea: Why not build a small butterfly house? Surprisingly, the toughest men I knew started asking me, "When will you6 the butterflies?" On the special day, over a hundred people7 to watch. We expected a wild flutter (飞舞), but instead the butterflies moved8. People stretched out their hands, and when a butterfly landed, they felt the most delicate little9.

The joy was unforgettable. The next year, we raised 120 monarchs. Last year, 350. This year we hope for more than 600. Looking back, I don't just remember the numbers; I remember how this project10 all of us.

For me, the most important thing wasn't the job itself but the people. I wanted them to know I11 about them. Watching the butterflies reminded me that life isn't only about getting things done. It's also about12 change and growth.

Like the monarchs, we also go through stages. From struggle to strength, from fear to hope, each of us can13 into something new. The process is slow, but the result is14. Just as the butterflies15 the sky, we also find freedom in transformation.

An exhibition at the Xi'an Beilin Museum is showing Chinese calligraphy (书法), has been regarded as both an art and a way to build character for (century).

Calligraphy is one of most valued cultural treasures in China, showing not only skill but also personality.

"At the exhibition, we hope (show) how old handwriting can come alive with digital technology," said a guide. "Visitors can see ancient stones beside modern screens, clearly showing the mix of tradition and innovation, and bringing new inspiration."

For thousands of years, handwriting (consider) as a way to record history and improve one's mind. Today, many of these works, kept through digital scanning and 3D modeling, regularly appear in online exhibitions. They are now open people everywhere, sometimes just by (click) a mouse.

The exhibition shows the balance between the (beautiful) of the rhythm of writing the feelings inside the lines. These features have encouraged artists to create paintings, sculptures, and (digital) produced works. Experts say cultural heritage, with the help of technology, will continue to inspire future generations.

Friendship in the new era takes many forms. In class, some students may with difficult homework, while others forget every small in a history lesson. At such times, a good friend will always step forward and, making challenges less frightening.

Conflicts, of course, are part of growing up. Friends sometimes in heated discussions, but the value of true friendship will unfold when they learn to listen and forgive. Teamwork makes this even clearer. Before a big game, players often promise to for their team, and victory becomes sweeter when shared.

Modern friendship is also shaped by technology. Young people can classmates through social media even after they graduate. It is easier than ever to connect hearts across distance new tools.

In the end, friendship is about loyalty and growth. Everyone should be their friends who always offer support and encouragement. At the same time, each person is also for protecting and cherishing such relationships. A lifelong friendship is not something we can simply as "luck"； it is built day by day through care and honesty.
