Strange things were happening in the countryside of northeast Hebei. For three days the water in the village wells rose and fell, rose and fell. Farmers noticed that the well walls had deep cracks in them. A smelly gas came out of the cracks. In the farmyards, the chickens and even the pigs were too nervous to eat. Mice ran out of the fields looking for places to hide. Fish jumped out of their bowls and ponds. At about 3:00 am on July 28, 1976, some people saw bright lights in the sky. The sound of planes could be heard outside the city of Tangshan even when no planes were in the sky. In the city, the water pipes in some buildings cracked and burst. But the one million people of the city, who thought little of these events, were asleep as usual that night.

THE NIGHT THE EARTH DIDN’T SLEEP

Strange things were happening in the countryside of northeastern Hebei. For several days, the water in the village wells rose and fell, rose and fell. There were deep cracks that appeared in the well walls. At least one well had some smelly gas coming out of it. Chickens and even pigs were too nervous to eat, and dogs refused to go inside buildings. Mice ran out of the fields looking for places to hide, and fish jumped out of the water. At about 3:00 a.m., on 28 July 1976, bright lights were seen in the sky outside the city of Tangshan and loud noises were heard. But the city’s one million people were asleep as usual that night.

At 3:42 a.m., everything began to shake. It seemed as if the world were coming to an end! Eleven kilometres directly below the city, one of the most deadly earthquakes of the 20th century had begun, a quake that even caused damage more than 150 kilometres away in Beijing. Nearly one third of the whole nation felt it! A huge crack, eight kilometres long and 30 metres wide, cut across houses, roads, and waterways. Hard hills of rock became rivers of dirt. In less than one minute, a large city lay in ruins. Two thirds of the people who lived there were dead or injured. Thousands of children were left without parents. The number of people who were killed or badly injured in the quake was more than 400,000.

Everywhere survivors looked, there was nothing but ruins. Nearly everything in the city was destroyed. About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone. Bricks covered the ground like red autumn leaves, but no wind could blow them away. Most bridges had fallen or were not safe to cross. The railway tracks were now useless pieces of metal. Tens of thousands of cows, hundreds of thousands of pigs, and millions of chickens were dead. Sand now filled the wells instead of water. People were in shock—and then, later that afternoon, another big quake shook Tangshan again. Even more buildings fell down. Water, food, and electricity were hard to get. People began to wonder how long the disaster would last.

But hope was not lost. Soon after the quakes, the army sent 150,000 soldiers to Tangshan to dig out those who were trapped and to bury the dead. More than 10,000 doctors and nurses came to provide medical care. Workers built shelters for survivors whose homes had been destroyed. Hundreds of thousands of people were helped. Water and food were brought into the city by train, truck, and plane. Slowly, the city began to breathe again.

Tangshan started to revive itself and get back up on its feet .With strong support from the government and the tireless efforts of the city’s people, a new Tangshan was built upon the earthquake ruins. The new city has become a home to more than seven million people, with great improvements in transportation, industry, and environment. Tangshan city has proved to China and the rest of the world that in times of disaster, people must unify and show the wisdom to stay positive and rebuild for a brighter future.

【推荐2】The California sea otter (海獭), once hunted to the edge of extinction, has staged a thrilling comeback in the last century. Now, scientists have discovered that the otters’ success story has led to something just as remarkable: the restoration of their declining coastal marsh (沼泽) habitat.

Elkhorn Slough, a coastal marsh within Monterey Bay, had been experiencing severe damage. The root cause was a growing population of shore crabs, which fed heavily on the marsh plants, weakening the structural integrity of the habitat. Coastal marshes like these are not only natural defenses against storm waves but also serve as important carbon storage areas and water-cleaning systems.

The conservation-driven comeback of the sea otter has been crucial. California’s coastlines were once alive with sea otters. Sadly, they were nearly wiped out at the hands of fur traders. In the 1980s, conservation efforts aided these otters in re-occupying large areas of their former range. Now, Elkhorn Slough has the highest concentration of sea otters in California, with a population of about 100. By naturally feasting on crabs, the otters have helped a significant regrowth of plant life. Brent Hughes, a scientist working alongside Angelini, led a three-year study. Their findings were clear: in areas with sea otters, crab numbers fell markedly. This led to a resurgence in plant growth, which in turn stabilized the soil and lowered the rate of soil washing away.

As the sea otter population continues to restore, their positive impact on coastal ecosystems is likely to increase. It not only showcases the sea otter as a central species—a species that has a significant effect on its natural environment—but also highlights the essential nature of top predators (捕食者) in preserving ecological harmony. “My honest reaction was—this could become a classic in the literature,” says scientist Lekelia Jenkins. She reveals marsh restoration also helps people by reducing flooding. “Suddenly, sea otters go from just cute things we like to something that can protect our livelihoods and our properties.”

......

Speaking to world leaders at the recent United Nations Climate Conference in Glasgow (COP26), Elizabeth issued a serious warning on the threat of climate change. Over two million of Kenyans are facing climate related starvation. In 2025, half of the world’s population will be facing water shortage. The climate crisis will displace 80 million people in sub-Saharan Africa alone.

Elizabeth said, “I have been doing what I can. Inspired by the great Wangari Maathai, I founded a tree growing initiative that enhances food security for young Kenyans.” So far, they have grown 30,000 fruit trees to maturity, providing desperately needed nutrition for thousands of children. “Every day we see that when we look after the trees, they look after us. We are the adults on this Earth right now, and it is our responsibility to ensure that the children have food and water,” she added.

【推荐1】Well, to pick up where we left off last time. I’m certain that you know all too well the dangers hiding on the World Wide Web. And whether it’s for schoolwork, entertainment, or just socializing with friends, the Internet will surely be a major part of your child’s life. So, it’s important to secure their online stays.

It’s not the easiest thing, but keeping open lines of communication is primary. Let them know they can share their online activities with you. Talk to them about their online presence as early as possible, ideally before they begin to use email, social media, or a smartphone. Discuss what they find interesting online and learning from them about popular websites and apps; this will create understanding and allow you to identify potential risks.

Next, monitor without spying. Most kids learn to understand boundaries, like respecting others’ personal space, or not opening the cookie jar without asking. Internet use is no different. It’s helpful for kids to have ground rules as to which websites they can visit,which apps they can use, and what they can share online. Remind them that if they feel uneasy with anything that occurs online, they need to alert an adult immediately.

Researchers trained a group of 11 dogs to distinguish between images (图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The researchers then tested the dogs’ ability to distinguish between human facial expressions by showing them the other half of the person’s face or images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.

The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. “We can rule out that the dogs simply distinguish between the pictures bused on a simple cue, such as the sight of teeth, ” said study author Corsin Muller. “Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.”

“With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,” Muller told Live Science.

At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans.“To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions, ” and this exposure has provided them with many chances to learn to distinguish between them, Muller said.

This huge dam is in the Black Canyon. It is possible to drive a car from one side of the river to the other on a road, which is on the top of the dam. This dam is so big that there is an elevator inside. The elevator goes down forty-four stories from the road to the bottom. There is enough concrete in this dam to build a highway from New York to San Francisco. Thousands of people worked on this dam for five years.

This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States. Hoover Dam, one of the highest dams in the world, is situated between the states of Arizona and Nevada.
