2 . You’re in the shower. You grab the showerhead. What do you do? You sing.
Have you ever wondered about this phenomenon? Some of us wouldn’t sing in public if someone paid us. Yet we’ll sing in the shower without embarrassment. Believe it or not, there’s a scientific explanation behind it.
First, let’s look at why we’re relaxed enough in the shower to burst into song. Think about it: you don’t sing when you’re sad (unless you’re singing the blues, of course). For many people, shower time is the only time they’re alone all day. You’re in a warm, small, safe environment. You’re comfortable enough to be yourself! When you relax, your brain releases dopamine (多巴胺), which can give your creative juices an extra kickstart.
Warm water is rushing over you, and now you’re relaxed and feeling good. It turns out that singing makes you feel even better. Singing, because of the breathing you put into it, gets more oxygen into the blood. This gives you better circulation, which in turn improves your body and mood. And because you have to breathe a little deeper to belt out a song, you get some of the same relaxation and mind-clearing benefits as meditation (冥想). Another neat thing is that when you’re singing, you really can’t think about your problems—more stress relief.
But the best thing about singing in the shower? The acoustics (音响效果)! You can never ask for a better sound system than a bathroom. Because bathroom tiles (墙砖) don’t absorb sound, your voice bounces back and forth around the room before fading away, which makes your voice hang in the air longer. And because the shower is a small space, it boosts your voice, making your singing sound more powerful. So you will sound better than you actually are, which is a confidence boost.
We don’t sing in the shower simply because we have “Call Me Maybe” stuck in our heads. It turns out we do it for many reasons: stress relief, happiness, great acoustics, or maybe just because we like to hear our own voices. Whatever the reason, keep it up. It’s good for you. And if you’ve never tried it, pick a song, grab the showerhead and put on your own private concert.

4 . Parrots are prey animals, which means that other predators (捕食者) in the wild, such as hawks or snakes, are looking to make them into a meal. This one factor influences parrots’ behavior in your house more than any other.
Parrots are most easily hurt when feeding on the ground. Membership in a group plays an important function in ensuring their safety and improving their chances of survival from attacks by predators. The most common predators of parrots include hawks, snakes, cats, monkeys, and bats. Some predators make attacks only during the day while others hunt in the night.
As prey animals, parrots are constantly watching out for danger and they instinctively (本能地) react to risks. Their first choice is to take flight. However, if this is not possible, they will fight with their powerful beaks to defend themselves.
Because their biggest enemy is the hawk, parrots are especially reactive to quick movements from above and behind. For this reason, it is wise to avoid quick, sudden movements near your bird. This is a built-in reaction not subject to logic or reason. Simple and relatively harmless household objects can draw extreme fear responses from a bird. For example, a balloon may represent a hawk or a vacuum hose (吸尘器软管) may be the same as a snake in your bird’s mind.
As prey animals, parrots are often frightened by exposure to new household items or strangers. It is important to expose your bird to safe experiences and changes starting at a very young age to build flexibility and improve their adaptability. Variety in diet and toys, travel, and exposure to new people and places all help to make your bird more flexible and adaptable to change.

6 . With kids going back to school, many parents are concerned about how their children will manage their behavior for eight hours a day. They may keep a watchful eye on their phone in case they receive a phone call from the school regarding their children’s behavior. If a child has difficulty controlling his words and behavior, a daily behavior report card may be a helpful option.
A daily behavior report card can be as simple as a chart on the child’s desk where his teacher provides ratings based on his behavior. The chart might be broken down into each class in a day. At the end of each class, the teacher will rate the students based on how well they did in meeting their behavioral goals. For example, a child might get scored on a 1—10 scale. Students will have a goal score to earn after each class. If they earn their goal score, they will get an instant experience-based reward.
Some advantages of the daily behavior report card are that it makes classroom expectations clear and gives kids frequent feedback on how they did and what they need to do to improve next time. While many teachers often promise a reward for good behavior at the end of the school day, this possibility of a reward is often too far for many kids to care. Instead, by offering a more prompt reward after each class that a child’s behavioral goal is met, their motivation level can stay high to control their attention and behavior.
Teachers are busy during the school days. They often have to manage difficult behavior in class and they lose lots of the classroom instruction time. However, using a daily behavior report card may be able to prevent difficult behavior from occurring in the first place. Meanwhile it will also improve the teacher-parent communication, which helps parents track and solve their children’s problems.

| A．Immediate. | B．Reasonable. | C．Necessary. | D．Minimum. |
| A．Multi-beneficial. | B．Universally true. | C．Widely available. | D．Quite complicated. |
7 . In August 2019, two citizen scientists, Sunniva Sorby and Hilde FalunStrom landed on Spitsbergen, in Norway’s Svalbard island group. They planned to work through the winter, then go home in May 2020. But their ship could not come because of COVID-19 shutdowns. For fourteen months, they lived in a small cabin on an icy island near the North Poles. Sometimes, hurricane-force winds forced freezing air through the cabin’s slats. Once, wind ripped the door open. Sunniva and Hilde couldn’t close it until the storm ended! Between storms, silence settled on the cabin. Then, they could hear the crunch-crunch-crunch of polar bears walking in the snow.
Their days started at 7 am and ended after midnight. Each morning, they wore down-stuffed jackets and pants as they waited for the wood-burning stove to heat the cabin. They cut pieces of freshwater ice to melt for drinking, cooking and bathing. For the stove, they gathered driftwood. They cooked their meals, including pizza! These tasks used up large stretches of each day. They also kept in touch with schools and other groups. They wrote blog entries and answered e-mails. For fun, they danced to music, exercised, practiced yoga and read.
“We are efficient here,” Sunniva wrote. “We have a routine, habits, and systems. We have time for what matters most living safely while making a contribution to our understanding of a changing world.” They conducted lots of experiments. They gathered data on climate change, using a drone (无人机) to measure sea-ice temperatures. They observed wildlife and tested new technologies, including an electric snowmobile.
To stay four extra months, they had to eat smaller amounts of food so they wouldn’t run out. “It was difficult being here, so far away from everything,” Sunniva wrote. “Food, shelter, and warmth are often taken for granted until you are on your own.” But, they wrote, “We have packed our patience, our smiles, and good spirits.” And they enjoyed the adventure, finding ordinary miracles every day.

8 . 3M and Discovery Education announced Sean Jiang from Gilman School as one of the top ten finalists from across the nation for the 2023 3M Young Scientist Challenge. It’s a competition that encourages students to identify an everyday problem and submit a video showing the science behind the solution he or she came up with.
14-year-old Jiang decided to help those who can’t see. Blind people had a hard time navigating (导航) objects that are medium to far range. So Jiang wanted to design something to give them a heads-up on obstacles (障碍) that may be incoming.
Jiang’s inspiration came from the powers of the hearing system. “I learned in school that bats and whales are able to use echolocation (回声定位) to help them navigate and just use their sense of hearing and I also saw on YouTube some very skilled blind people that use echolocation to help them walk,” said Jiang.
Jiang started with a virtual reality setting and then made it a reality. His creation uses a depth camera that can detect how close objects are, thus giving enough time to dodge the obstacles. When a blind is walking with the device, the sensor of the depth camera gathers the information regarding the obstacles’ position and distance. Then the AI system in it will turn the distance data into musical sound guidance. This could significantly increase the walking speed of a blind person as well as decrease the number of obstacles they hit.
Some other similar programs were alright at finding objects that were in close range, but Jiang still wanted the blind to experience the world even fuller so they were able to see stuff that was much further away than their circle of reach.
In October, the top ten finalists will compete in person in Minneapolis for the title of “America’s Top Young Scientist” and a $25, 000 prize.

10 . When most kids go to the beach, they’re too focused on making sandcastles and splashing around to notice litter, but several years ago, for 7-year-old Cash Daniels, noticing a plastic straw sparked a lifelong passion for saving the planet.
Cash, who is now known as the “conservation kid”, has always loved nature. He grew up fishing along the Chattanooga River, after all! But once he learned that 80 percent of all trash from land and rivers ends up in the ocean, he couldn’t sit back.
He started with cleanups along the river, something that quickly went from a family affair to a community effort with volunteers and neighbors. In 2019, Cash, together with a Canadian conservationist, Ella Galaski-Rossen, started a nonprofit called the Cleanup Kids. Despite living in different countries, they managed to create educational videos on their YouTube channel. “We hope to be a really big nonprofit that eliminates plastic in the U. S. and Canada,” Cash said. “We want to inform kids and adults in the landlocked states of how their actions are connected to the water and the ocean,” Cash said.
Cash was selected as one of America’s top 10 youth volunteers of 2021 by the Prudential Spirit of Community Awards. He also earned the title of National Honoree, where he received a$5,000 grant to go to a nonprofit of his choice, and he became the first person to win the Youth Conservationist Award two years in a row from the Tennessee Wildlife Federation.
“I want to travel the world, teach others, and help them feel connected to the ocean. Because if you are connected to the ocean-if you love it and what lives in it—you’ll want to protect it,” he said. “This is my fun, and it becomes more fun with every new discovery.”
