1 . When people delay (延迟) their bedtime, they think they’re prioritizing (优先考虑) some much-needed self time. But sleeping should be thought of as a necessary form of self time.
Move up and add your self time
Don’t hang out in bed
When you play on your phone or watch TV in bed, you’re training your brain to think that’s what you’re supposed to do in bed.
Create a relaxing bedtime routine
Some people have lost the opportunity to have a good bedtime routine. Create one that you look forward to.
Around bedtime, the first time you get sleepy, you have about 20 minutes to fall asleep. If you miss that window for any reason, then you’ll find it harder to fall asleep and not sleep for more than a few hours. If your body tells you it’s time to sleep, trust it. Put off any tasks until the next morning, and get some good shut-eye.
| A．Trust your body |
| B．Sleep is a basic human need |
| C．Avoid sleeping in on the weekends |
| D．You’d better make full use of your phone |
| E．A good rule is to keep your bed for sleeping |
| F．Consider changing your self-care tasks to earlier in the day |
| G．The key is to do whatever you find most calming and enjoyable |
2 . Tiny, black-capped chickadees (北美山雀) have big memories. They store food in hundreds to thousands of different locations in the wild—and then come back to these places when other food sources are low.
Scientists have known that chickadees have incredible memory skills. That memory can be a matter of life or death for these birds when there are no enough food resources in colder months.
Some researchers thought that neurons called place cells (细胞) would explain these birds’ ability to remember where their food is stored. These cells are known to include information about where things are in space. But recently, Selmaan Chettih and his team found that each time a chickadee hides a seed (种子) in a specific location, a unique brain pattern appears—separate from place cells.
To observe this, Chettih and his team created special areas with lots of feeders filled with sunflower seeds. They put small flaps (片状下垂物) where birds could hide seeds.
The scientists tracked the activity in their brains. Each time a bird hid a seed under a flap, researchers saw a brief unique brain pattern appear—what they called the bar code. Different patterns appeared even if the birds hid many seeds in the same location. When the birds revisited these sites and retrieved the hidden seeds, the same bar code-like pattern appeared again, as though all the information about each location and seed were related to a unique brain pattern.
The researchers compared these memories to episodic memories in humans, which are memories of specific events or personal experiences. They’re important to how humans connect time, people, places and sensory information together.
Chettih says that this seed-hiding behavior has a clear pattern of activity, which may help researchers build a structure for how the brain creates and stores memories.

3 . Can a robot provide helpful answers to your health concerns? That’s the goal of Reach Digital Health, an organization that uses mobile technologies, like text messages, to provide helpful health-care information and guidance to people across Africa who can’t easily reach a health-care provider. The continent has 17.89% of the world’s population, 23% of the diseases that disable and kill people, and only a small part of the world’s health workers.
Reach Digital Health deals with millions of questions and sends millions of mostly automatic (自动的) and computerized answers per day. That is, “We first try to respond automatically to any question that they might have,” says Debbie Rogers, CEO of Reach Digital Health, “because we want to be able to give them an answer as quickly as possible.” Besides, some words or responses can bring other interventions (干预). If someone describes an emergency like “bleeding” in their message, for example, the system will instruct them to visit their nearest hospital as soon as possible. In addition, signs and diagnoses (诊断) reported through Reach Digital Health can be sent to governments in real-time so that informed public health decisions can be made quickly and responsibly.
Reach Digital Health also uses the information they collect to improve the health offerings of equipment, district or even entire country. It collects information from millions of women, which allows for shortcomings in training or medical supplies to be identified and corrected by providers and governmental health agencies.
The organization isn’t just in South Africa. It’s working in eight other countries in sub-Saharan Africa. In addition, through teamwork with the World Health Organization starting in 2020, they’ve enlarged their services across the globe and set up programs in Bangladesh and Indonesia.

6 . David Brunelli has eaten up a huge burger. He starts eating handfuls of French fries. If he eats them fast enough, he could win. The crowd shouts with excitement. Suddenly, a stream of food pours out of Brunell' s mouth. Puking (呕吐) during an eating competition means you lose. So Brunelli catches the food in his hands and pushes it back into his mouth. Welcome to the world of competitive eating.
Thousands of eating competitions take place around the world each year. To win, people like Brunelli eat huge amounts of food as quickly as possible.They eat everything from mountains of hot dogs to hundreds of chicken legs.
Some people say it is time for eating competitions to stop. One reason is that the competitions can lead to serious health problems. These include weight gain, heart disease, and stomach problems. In 2004, a woman died from choking (窒息) during a competition. Eating competitions can make overeating look attractive. This sets a bad example for fans. Also, millions of people in the world go hungry every day. That makes it seem wasteful to eat amounts of food just for fun.
Still, many people love competitive eating. They say it is a fun tradition that goes back many years. Fans point out that the group Major League Eating (MLE) runs professional eating competitions. At these competitions, injuries are uncommon. MLE always has doctors on hand.
Eating competitions allow people like Brunelli to get famous and win money. And the competitions are popular. Each July 4, more than a million people watch Nathan s Famous Hot Dog Eating Contest on TV. This year, will you be one of them?

7 . Bailey Martin was like many of her sixth-grade classmates at age 12. She played sports and loved to read. But one night, Martin was in bed and covered up her left eye. She realized something wasn’t right. “I noticed I couldn’t really see anything,” she said. She went to the hospital. A doctor in Chicago discovered that it was acute macular neuroretinopathy (急性黄斑神经视网膜病变), a rare disease without a known cure. She was declared blind.
At first, she had to learn Braille (盲文) to read. But what of sports? She didn’t want to lose that part of her life. “I just really didn t want to give up, and I didn’t want to give up who I was as a person,” Martin said. So, that summer, she competed at the Iowa State Fair, showing her horse. When she returned to school at South Hamilton, she joined the cross-country team. “And once I started playing a few different sports again, it not only helped me grow my confidence back, but it also made me realize just how much I love sports and how much sports can really help with finding yourself,” Martin said. She was determined to keep going.
“She chose to run without a guide. It wasn’t easy, but she made it work, running on the team through ninth grade. She made it through the season,” her mother Sara Martin said. “She hit lots of trees. It didn’t t stop her. She wasn’t afraid of getting hurt.” Her parents warned her it could happen, even if she had her sight. “ We’ d rather have you hurt trying something than be too scared to try,” Sara told her daughter.
So, Martin kept going. Now, the 18-year- old senior at South Hamilton High School plans to compete in the Paralympics (残奥会).
Martin is driven to keep going and keep competing. The fact that she’ s overcome as much as she has even surprises and encourages herself.

8 . Sunlight has a lot more to offer. than just brightening our day. Sunlight helps our body make a certain hormone (激素) in our brains. The hormone not only eases worry but also stabilizes moods.
Our skin produces vitamin D when exposed (暴露) to the sun’s ultraviolet (UV) rays (紫外线).
If you would like to drop a few kilograms, think about spending about a half hour in the sun early in the day.
COVID-19 is sometimes deadly. But some studies suggest that the sun’s UV rays may offer some protection. Last April, a Scottish team published the results.
