Several days ago, local News Channel reported a story between a mother and her son. The mother was a single woman who had been feeling a great deal of anger and bitterness due to her financial and psychological problem, causing her emotions to be unpredictable. Occasionally, she may not pay enough attention to her son or couldn’t respond to his requirements timely. Sometimes, she would even pour her negative emotions onto her child, which made him feel helpless. In fact, this child is a very outstanding and caring boy.
That day, the mother directed her anger towards her child again because of some small matter. Although the child did not resist, the mother still drove the child out of the house, slammed the door shut and left the child outside to reflect (反省).
It was when the mother became calm and a little regretful that she opened her door and found her child missing. Anxious and scared, she searched everywhere, but the child was nowhere to be found. Her anxiety was gradually increasing.
The worried mother thought of seeking help from the police. Quickly, she went to the police station and explained the situation to the officer on duty. The police officer explained that, as a general rule, they couldn’t file a case for a missing child within the first 24 hours. However, they could provide assistance in other ways, such as posting the child’s photo on social media platforms to expand the search area.
After expressing gratitude for the police officer’s kindness, the mother continued searching for her child. Despite trying various methods, the mother still couldn’t find the child. Unexpectedly, the child was wandering in the streets, he felt lost and alone, not knowing where to go or what to do. He felt the tears forming in his eyes but refused to let them down. He didn’t want to show weakness in front of anyone, and it made him feel even more alone.

2 . Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe Studies by the Council of Europe of which 21 countries are members have shown that 45 per cent of reptile species and 24 per cent of butterflies are, in danger or dying out.
European concern for wildlife was outlined by. Dr Peter Baum, an expert in the environment and natural resources division of the council when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council’s diploma for nature reserves of the highest quality and Dr Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks and that those set up in the 1960s and 1970s could not he set up today. But Dr Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.
“No area could be expected to survive both as a true nature reserve and as a tourist attraction.” he went on. The shortsighted view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future.
“We forget that they are the guarantee (保证) of life systems on which any built-up area depends,” Dr Baum went on. “We could manage without most industrial products but we could not manage without nature. However our natural environment areas which are the original parts of our countryside have become mere islands in a spoiled and highly polluted land.”

3 . When a chunk of ice fell from a collapsing glacier(冰川)on the Swiss Alps’ Mount Eiger in 2017, part of the long deep sound it produced was too low for human ears to detect. But these vibrations held a key to calculating the ice avalanche’s(崩塌)critical characteristics.
Low-frequency sound waves called infrasound that travel great distances through the atmosphere are already used to monitor active volcanoes from afar. Now some researchers in this field have switched focus from fire to ice: dangerous blocks snapping off glaciers. Previous work has analyzed infrasound from snow avalanches but never ice, says Boise State University geophysicist Jeffrey Johnson. “This was different,” Johnson says. “A signature of a new material has been detected with infrasound.”
Usually glaciers move far too slowly to generate an infrasound signal, which researchers pick up using detectors that track slight changes in air pressure. But a collapse—a sudden, rapid breaking of ice from the glacier’s main body—is a prolific infrasound producer. Glacial collapses drive ice avalanches, which pose an increasing threat to people in mountainous regions as rising temperatures weaken large fields of ice. A glacier “can become detached from the ground due to melting, causing bigger break— offs,” says University of Florence geologist Emanuele Marchetti, lead author of the new study. As the threat grows, scientists seek new ways to monitor and detect such collapses.
Researchers often use radar to track ice avalanches, which is precise but expensive and can monitor only one specific location and neighboring avalanche paths. Infrasound, Marchetti says, is cheaper and can detect break—off events around a much broader area as well as multiple avalanches across a mountain. It is challenging, however, to separate a signal into its components (such as traffic noises, individual avalanches and nearby earthquakes) without additional measurements, says ETH Zurich glaciologist Malgorzata Chmiel. “The model used by Marchetti is a first approximation for this,” she says. Isolating the relevant signal helps the researchers monitor an ice avalanche’s speed, path and volume from afar using infrasound.
Marchetti and his colleagues are now working to improve their detectors to pick up more signals across at-risk regions in Europe, and they have set up collaborations around the continent to better understand signals that collapsing glaciers produce. They are also refining their mathematical analysis to figure out each ice cascade’s physical details.
