1 . Whenever he can, 15-year-old Elliot Morgan practices basketball in his backyard. He says it’s a good stress-reliever. But it wasn’t that long ago that he didn’t have time for this new hobby. “There were times in the summer when I would spend four or five hours a day on my phone,” he says. When school started in the fall, Morgan found himself scrolling (划屏) as soon as he woke up. “I realize I start to avoid workouts because I’m on my phone,” he says. “It’s affecting my focus.”

It has become clear that social media is a key player in many drivers of unhealthy habits. Social media apps are designed to encourage overuse, and teenagers are more likely to be influenced because their brains are at an important period of development that makes it harder to be free from temptation (诱惑). All of this makes limiting use more challenging — even for families who set rules.

“It’s a really big problem,” says Elliot’s mom, Alyssa. She was shocked when she discovered Elliot had bypassed parental controls and was spending five hours a day on social media. “I asked him, ‘Can you just take a look and see? Just tell me what you think. Does this feel good to you?’” she says.

Elliot hadn’t realized how many hours he was on social media. And he was at a loss. With his mother’s help, he tried to start cutting back. After several months, he decided to delete (删除) social media apps altogether. “After that, I actually sleep enough and feel better,” he says. He’s now closer with his friends because they spend more time talking instead of scrolling. And joining school clubs has also helped him reduce time on his phone.

3 . A four-year-old dog named Kob became a hero in its neighborhood by discovering a possibly life-threatening gas leak (泄漏) in its owner’s front yard.

This dog’s actions not only _______ its surroundings, but also stressed the importance of the behavior of our furry friends.

The story began when Kob, _______ by 28-year-old Chanell Bell, started digging a large hole in the yard. At first, Bell thought this was typical dog _______, but as the hole grew larger, she became _______. Recognizing that Kob’s actions were unusual, she trusted the dog’s judgment, considering its normally well-behaved nature.

After _______ a recent gas leak in her home, Chanel _______ a gas detecting (探测) tool. She followed her sense and chose to use the tool to _______ the newly dug hole by Kob.

Finding gas coming out of the hole, Bell _______ contacted the authorities about the issue.

“If it wasn’t found, the _______ would have continued to escape into our homes,” Bell said. “We were told it could have caused ________ health effects like breathing issues, brain damage, and even ________. They told me that something as simple as ________ a light could have caused a burst!”

During the repairs, workers ________three main gas leaks in Bell’s neighborhood caused by aging ________. It took the workers over three days to repair the leaks and replace the old equipment.

Throughout the repairs, the workers________ Kob for saving the neighborhood.

4 . The ocean depths contain the metals needed for the widespread use of battery-dependent technologies like electric vehicles, which will help reduce greenhouse gas emissions. Interested parties see this as a solution to our technological demands and the pressing need for a “green transition”. However, it raises a crucial question: should we mine the deepest stretches of the world’s oceans?

Some scientists and activists warn that seabed mining could cause an irreversible (不可逆的) chain reaction, severely harming the ocean and threatening entire ecosystems on the ocean floor. There are also potential risks to our health, including toxic metals entering the human food chain, and affecting climate change. The most significant direct impact of mining in remote ecosystems is the probable loss of habitat and biodiversity.

Dr Chong Chen is a deep sea biologist at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). “There are undoubtedly many undiscovered species with abilities and functions that we cannot even imagine exist,” he says, “and we could lose them without knowing they ever existed.”

The mining process also disturbs seabed sediments (沉积物) and releases them back into the sea, raising additional concerns among scientists. Mining is for metals, whose stability of the construction are unchecked. “Some of those may be broken down and be directly into the water column,” says Jeffrey Drazen, professor of Oceanography with the University of Hawaii at Manoa. “Some of these metals are toxic to life.” says Professor Drazen. At the same time, he acknowledges the core challenge is ensuring whether the benefits of extracting (提取) deep-sea mineral resources outweigh the potential harm to our ecosystem. He notes that it’s a tough choice.

The positive development is that, for the first time, companies, governments, and civil society are actively participating in international discussions to create rules and regulations for the deep-sea mining industry before it begins.

7 . Which is more important for parents, making more money to give the kids a better life or spending more time with them? It is a problem for parents and it is not easy to decide. A new study shows that today’s parents are spending more time with their children than parents in the past. According to the study, today’s college-educated mothers spend about 21.2 hours a week taking care of their children. But women with less education spend about 15.9 hours. Before 1995, it was only 12 hours.

Dads are spending more time on ball games. Before 1995, fathers with college educations only spent about 4.5 hours a week playing with their children. Today, it increases to 9.6 hours a week. For fathers with high school education, the time goes up from 3.7 hours to 6.8.

These days, parents don’t care more about the cleaning or the cooking. They are trying their best to spend time with their families. As for the kids, they don’t mind how much time their parents spend with them. They just want to enjoy the time their parents do be with them.

So, take part in the kids’ activities when you are with them, such as helping with homework or playing soccer with them.

9 . New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life.

Researchers at the University of Ponsmouth have discovered that rates (率) of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel (船) positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK.

Lead author, James Robbins said: “This change is likely to put more pressure on the marine (海洋的) environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment.”

Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds.

Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said: “Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales.”

Professor Alex Ford. from the University’s Institute of Marine Sciences, said: “Given the well-documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable (脆弱的) species which may already be under pressure.”
