Why did Li's stall get so popular? First, he talked with customers in a funny talk show style. His lively chats made everyone feel relaxed and happy. Second, his fried chicken was cheap: one piece cost only 6 yuan. Third, he cared a lot about students. He gave students discounts and served them first after 4:30 pm every day.

Li's stall brought nice changes to Jingdezhen. Every day, more than 5,000 tourists came to his stall. This even made the city's travel bookings rise by 10%. Because of his great service, Li was hired as the "tourism promoter" of Jingdezhen. Local workers also helped keep order at his stall due to the large crowds.

Li has run the stall for 9 years. He always focused on making delicious chicken and being kind to every customer. His story tells us: "Sincerity is the best skill." Small, warm acts can turn an ordinary stall into a popular spot—and even help the local tourism develop.

Yang Zhenning is one of the greatest physicists of the 20th century. His life story stands as a guiding example for everyone.

Born in 1922, Yang showed a(n)1 talent for science at a young age. He could quickly understand difficult science books that even some older students found hard. In 1938, he2 Southwest Associated University and studied hard there. His solid education3 his future success.

In 1957, Yang won the Nobel Prize in Physics. This4 made him the first Chinese to get this high honor. His discovery changed people's understanding of physics greatly.

Though living abroad for years, Yang always cared about his home country. In 1971, he returned to China and5 a bridge for scientific exchanges between China and the US. He also6 advised China to pay more attention to basic science——this advice helped China develop science faster later.

In 1999, Yang joined Tsinghua University as a professor. Even in his 80s, he still taught students carefully and tried to7 a new generation of researchers. He often shared his experience to help them solve problems. His8 devotion to science and country won people's deep respect. Many young scientists look up to him because of this.

In 2021, Yang donated over 2,000 valuable9 to Tsinghua University, including his old books and research manuscripts. These things help people learn more about his life and work.

Yang Zhenning is truly a role model. He proves that hard work and love for the country can make a10 in the world.

The Yellow River Delta (三角洲), formed by vast amounts of mud and sand carried by the river, gave rise to Dongying, a city in East China's Shandong Province.

Situated at the river's mouth where it meets the Bohai Sea, Dongying has over 4,567 square kilometers of wetlands, c 41.6 percent of its area. The city is k as one of the world's first International Wetland Cities, and the Yellow River Delta National Nature Reserve is also a UNESCO World Heritage site.

The reserve h 1,633 animals and 685 plants. More than 200 migratory birds visit every year for breeding (繁殖), wintering, or rest. The best birdwatching s runs from October to April, when tens of thousands of birds fill the sky a the estuary (河口), forming shapes that resemble (类似) a giant whale or drifting clouds.

This year's birdwatching season began on Nov 15. Shahbaz Khan, director of UNESCO's Regional Office for East Asia, believes the reserve sets a good e of international cooperation in protecting nature.

However, the reserve used to be quite d in the past. In local people's m, the reserve was once saline-alkaline land (盐碱地), with wild grasses and sand f the air. Over the years, Dongying has been working on wetland protection and restoration (修复), making it China's largest new coastal wetland zone.

Even within the city, wildlife is alive and well. A crested ibis (朱鹮), a nationally protected bird, has made Mingtan Park its home since October 2024. A Dongying is a major crude oil (原油) production center, the city still shows that its development can coexist (共生) with nature.

Here, modern buildings and flocks of birds share the skyline—a new vision of a city that becomes part of nature itself.

Have you ever stopped to look closely at moss (苔藓) on a stone or a giant redwood reaching for the sky? Our planet is full of amazing living things, from the fastest cheetah (猎豹) to the tiniest ant. But these plants and animals don't live alone. They depend on each other in a web of life called an ecosystem.

Every living thing plays a role in this network. For example, bees and butterflies are very important for pollination (传粉). They carry pollen (花粉) from flower to flower. If there is no such action, many plants couldn't make fruits or seeds. Bees also communicate to find food and store sweet honey in their honeycomb (蜂巢).

Other small living things, like mushrooms, help to break down dead plants and animals, cleaning the forest and making the soil rich. This process removes decaying (腐烂的) things and creates nutrient-rich food for living plants. This amazing cycle shows how everything in nature is connected— even death gives life to new growth.

Sadly, sometimes these connections are broken by human activities. When we cut down too many trees like bamboo or ginkgo, animals lose their homes. Forests, which once offered the living space to many frogs and butterflies, have fallen silent.

Protecting nature means protecting ourselves in the long run. We can start small— plant trees or grow flowers like roses. When we understand we are also part of the ecosystem, we can learn to live in harmony with nature. Every effort we make today, whether big or small, will help build a better future for the natural world.

In winter, many birds berries and seeds they find in the forest.

Cutting down too many trees fewer homes for wild birds in the past.

We must now to wild animals losing their homes.

to plant trees in spring because it helps the ecosystem.

What are glaciers?

You can imagine glaciers as slowly-moving ice and snow on land. Over time, the snow adds up and turns into glacier ice. Glaciers have shaped mountains over the earth's history. They are still moving and changing land in many places today.

   ▲   

Glaciers are not just needed for the land. When glaciers melt, the nutrients (养料) from the water are good for life in rivers and oceans. In some places, glaciers provide water for people and animals. Glaciers in the world cover 10% of the land. They also hold 70% of the earth's fresh water. In areas like the Himalayas, many people need glacier water to live. This water fills big rivers, such as the Indus, Ganges and Brahmaputra.

Why are glaciers disappearing (消失)?

Climate change is leading to serious problems for glaciers. Many glaciers have disappeared. The atmosphere (大气层) around the earth is like the glass of a greenhouse, letting sunlight in and keeping most heat from getting out. This makes the earth warm enough for life. But when we burn wood and coal, we produce a gas called carbon dioxide. Too much of this gas pollutes the atmosphere and causes it to keep in too much heat. As the earth's temperature is increasing, glaciers melt faster.

The influence (影响) of glaciers disappearing

If glaciers disappear, there will be less water for us to drink and farm, while floods may happen more often. Mountains with glaciers are home to special ecosystems and a large number of animals. As temperatures rise and glaciers melt, they are not fit for these living things.
