Wucheng: A Winter Home for Birds and People
Every winter, a small town near Poyang Lake becomes the world’s busiest “bird airport”. Over 600,000 birds arrive in Wucheng, Jiangxi. Among them, there are about 4,000 white cranes (白鹤)—that is almost 98% of their world’s population.
To protect these important visitors, Wucheng built special safe zones. Nearly 1,600 white cranes gather (聚集) at Dahu Pond. Nearby at Changhu Pond, about 30,000 ducks swim and dive for food. These amazing sights attract thousands of birdwatchers, who use cameras and telescopes (望远镜) to discover wildlife. One of the birdwatchers, Lin Yue, said, “After the trip, I realized how closely connected we are with nature here.”
In fact, things were totally different here ten years ago. Local fishermen used to catch birds and fish. Now, many have become protectors. Zhang Haiping, for example, runs a popular hotel and farms rice in Wucheng. In autumn, he always leaves part of his rice for the hungry birds. As bird numbers rose, so did tourism. Thanks to the bird tourism, Zhang makes ten times more money than before.
Wucheng’s story shows a powerful truth: protecting nature not only saves wildlife, but also feeds local communities.

B．White cranes only live in safe zones.

Protecting Natural wonders: Our Shared Responsibility
Natural wonders are precious gifts from the earth. They include majestic mountains, deep lakes, vast deserts, lush rainforests and other amazing landscapes. These wonders not only showcase the beauty of nature but also play a crucial role in maintaining the earth’s ecological balance.
However, many natural wonders are facing serious threats. Human activities such as pollution, over-development and illegal hunting have damaged some of these treasures. For example, Mount Qomolangma is polluted by climbers’ rubbish, Lake Baikal is affected by industrial waste, and rainforests are being cut down for wood. If we do not take action, these wonderful landscapes may disappear forever.
Protecting natural wonders is not only the responsibility of governments but also of every individual. Here are some practical ways we can help: First, follow the rules when visiting natural wonders—do not litter, do not damage plants or animals, and do not make excessive noise. Second, spread environmental awareness to our family and friends, encouraging more people to join in protection activities. Third, support environmental protection policies and organizations.
We should remember that natural wonders are irreplaceable. They are not only for us to enjoy but also for future generations. By working together, we can protect these precious gifts and ensure that the earth remains beautiful and vibrant.

A conversation with a whale
Some scientists teamed up and spoke to a humpback whale( 座头鲸) named Twain. Their conversation took place after the scientists sent a “communication call” into the ocean off the coast of Alaska. The same call was made 36 times over a 20-minute period. Each time, Twain called back. Professor McCowan said that the research could make it easier to talk to aliens and better understand what aliens’ intelligence might be like.
_____________
Scientists use technology to train dolphins to learn more about the ocean. They put small sensors ( 传 感 器 ) on dolphins. These sensors can get information about water temperature, saltiness and ocean flows. Then the sensors send the information to scientists for study right away. Dolphins swim well and have great senses. With the help of technology, they become good helpers for scientists to study the ocean.

71．例文
Welcome to Guilin
As far as we know, the mountains and water in Guilin are the first in the world. If you want to visit one of the natural wonders, come to Guilin!
Located in the northeast of Guangxi Zhuang Autonomous Region, Guilin is famous for its dreamlike wonderful landscapes. The Li River flows gently through the city, surrounded by unique mountains that rise straight from the water. These peaks create a magical scene which seems like traditional Chinese paintings.
A boat trip along the Li River is a must-do experience. As you travel on the river, you’ ll pass water bamboo forests swinging in the wind, and see fishermen fishing on the small boats. The riverbanks are dotted with ancient villages where time seems to stand still in green fields.
Whether you visit in spring when wildflowers bloom or autumn for clear skies, Guilin’s beauty will leave you great e and see why this place is called “the finest scenery under heaven”!
