Walk down any street, and you will see a common sight: heads bent down, eyes fixed on a glowing screen. Smartphones have become an extension of our hands in the 21st century. There is no doubt that this invention has changed how we communicate and learn. Some researchers and teachers are starting to worry that these devices might actually be weakening our memory and attention span.

One major concern is "digital amnesia." For example, instead of remembering your best friend's phone number or the directions to a restaurant, you simply rely on the phone to do it for you. Because we know the information is saved in our pocket, our brains make less effort to store it.

Furthermore, the constant buzzing and ringing of notifications is a huge distraction. Every time your phone makes a sound, your attention is pulled away from the present moment. Studies show that even having a phone face-down on a desk can lower your cognitive performance because your brain is still thinking about it subconsciously.

However, it would be unfair to call smartphones entirely bad. They connect us with family far away, provide access to endless educational videos, and can help us organize our busy lives. The key is not to throw the phone away, but to learn how to use it as a tool rather than being controlled by it.

The solution might lie in "digital mindfulness." This means setting clear rules for when and where to use your phone. For instance, you might decide to put the phone in another room while doing homework. By being aware of the habit, we can enjoy the benefits of the new era without losing our ability to think deeply.

A. This makes it very hard to focus deeply on a book or a conversation.

B. But is this constant connection always a good thing?

C. They also help us find jobs and make new friends more easily.

D. This term describes the habit of forgetting things because we trust our devices to remember them.

E. In the future, smartphones will likely replace computers completely.

F. They have brought incredible convenience to our daily lives.

G. Another good habit is turning off notifications for social media apps.

Saving the black-footed ferret was not easy. The main problem was the loss of its food source: the prairie dog. Farmers and ranchers often viewed prairie dogs as pests that damaged fields and caused injuries to cattle. As prairie dog towns were destroyed, the ferrets had nothing to eat. To bring the ferrets back, scientists first had to protect the prairie dogs and change people's opinions about them.

Scientists started a special breeding program. They captured the last wild ferrets and brought them into safe, controlled environments to have babies. At the same time, they worked with local communities to create protected areas where both prairie dogs and ferrets could live without being harmed.

Today, thanks to these efforts, there are about 300 black-footed ferrets living in the wild across North America. While this number is still small, it is a huge victory for wildlife protection. The story of the black-footed ferret teaches us that even when a situation looks hopeless, hard work and science can bring a species back from the very edge of extinction.

Unlike traditional bullying, which happens face to face and can be noticed by teachers or other students, cyberbullying happens online and is easy to miss. It can include spreading rumors (谣言), or sending some hurtful messages. This makes it even more important for schools to find ways to stop it, but they don't have a good way to find out about the problems in the first place.

Technology can help with this. A tool called Go Guardian Beacon can watch what students are doing on their computers. It uses a machine learning model to look for signs of cyberbullying, like hurtful messages or threats. If it finds something, it can tell schools, who can then take action.

Another tool, from Lightspeed Systems, checks students' online activities to find concerning behaviors. It uses AI to understand the context and figure out if something is meant to hurt someone. If it finds a problem, a team of safety specialists will even contact the schools directly to let them know.

By using technology, schools can respond faster and more effectively to cyberbullying, keeping students safer and happier.

On July 22^nd — exactly six months into her volunteer work — a sudden storm hit, with thunder crashing nonstop. By nightfall, nearby rivers overflowed, and floodwaters rushed into the village, trapping families in their homes. Sophie was carefully preparing for the students' lessons for the next day in her room when she heard people crying out in fear from outside. She immediately went to the door and saw water rising fast around the houses.

Picking up a boat borrowed from a local fisherman, she waded (蹚水) through waist-high water toward the cries. 9-year-old Amara and her 5-year-old brother Kofi were trapped in the water, holding onto a wooden chair. "Ms. Sophie's boat shook in the water, but she held us close until we reached the dry shelter (庇护所)," Amara later said.

The next day, at the shelter under a tree, Sophie didn't forget her role as a teacher. She devised some simple lessons — she used stones and sticks to teach the students. "Learning gives us hope," she said.

As the end of one year's volunteer work came, it was time for Sophie to go back home. Before she left, the villagers held a simple but sincere farewell party. The memories of the life in the village lasted forever in Sophie's heart.
