The college entrance examination is just around the corner. Homework and tests will keep many of you up late at night, and you may plan to make up for your lost sleep during the weekends. {#blank#}1{#/blank#} is it useful? A study published in the journal Current Biology completely has changed {#blank#}2{#/blank#} people used to think. It shows that the habit of sleeping in on weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}3{#/blank#} (bad), it may damage your health.

Earlier this year Rodney Smith Jr. made headlines when he drove eight hours from his home in Huntsville. Alabama, to cut the lawn for an elderly soldier in North Carolina who couldn't find anyone to help him with his yard work.

That wasn't the first time the twenty-nine-year-old Bermuda native had gained such attention. To do his good deeds, Rodney often finds leads for those in need through social media.

Back to one August afternoon in 2015, Rodney Smith Jr. was driving home. That's when Rodney saw an elderly man struggling to mow his lawn. He would take a couple of shaky steps, using the handle to stabilize himself, pause, then slowly push the mower again. Rodney decided to help. Mr. Brown thanked him greatly, and Rodney went home feeling satisfied.

Sitting at his computer to do his homework, Rodney couldn't get Mr. Brown out of his mind. There must be many Mr. Browns out there. He went online and posted that he would mow lawns for free for senior citizens. Messages flooded in.

One day a cancer-battling woman said she wasn't having a good day. Rodney decided to do more than mowing lawns. After he finished mowing, he knocked on her door. "You're going to win this fight, Madam", he said. Then he asked folks to pray for her on social media.

Word of Rodney's mission spread. A grandmother in Ohio said he'd encouraged her 12-year-old grandson to mow lawns. He got a letter from a seven-year-old boy in Kansas. "Mr. Rodney, I would like to be a part of your program, and I'll make you proud," he wrote.

That gave Rodney an idea. In 2017, he decided to establish a programme Raising Men Lawn Care Service to make a national movement for young people. The kids learn the joy of giving back.

Yard work seems like a small, simple thing, but taking care of the lawn means a lot to the people they do it for. "When we mow their yards for free, they can use the money for healthcare and food etc. It means more than you would think," Rodney said.

Adults check their phones, on average,360 times a day, and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our emails or social media feeds, and suddenly we've been sucked into endless scrolling.

It's an awful circle. The more useful our phones become, the more we use them. The more we use them, the more we lay neural（神经的） pathways in our brains that lead to pick up our phones for whatever task is at hand-and the more we feel an urge to check our phones even when we don't have to.

What we do know is that the simple distraction of checking a phone or seeing a notification（通知）can have negative consequences. This isn't very surprising; we know that, in general, multitasking does harm to memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It's true for everyday tasks that are less high-risk, too. Simply hearing a notification "ding" made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task.

It isn't just the use of a phone that has consequences-its me re presence can affect the way we think.

In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible（like on a desk）, nearby and out of sight（like in a bag or pocket）, or in another room. They were found to perform far better when their phones were in another room instead of nearby-whether visible, powered on or not.

It was a typical weekend for Mitch White and his friends. They were out celebrating a bachelor party, sailing the peaceful waters of the Minnesota River. They never expected that this single party would transform from a relaxed canoe trip into a painful rescue mission. With the sun setting, an unexpected bark changed everything.

Led by Mitch White, the soon-to-be-married man, they searched for the source of the sound along the banks of the river. Suddenly, a weak cry for help came from the mud. They were surprised to find that the head of a 13-year-old St. Bernard named Ed was barely visible in the thick mud. Mitch said, "The dog wasn't moving on its own, so we should feed it and give it water. " The dog looked like i had used all its strength.

The men took up their oars（桨） and began digging, their festive mood giving way to a focused rescue mission. It took them more than half an hour to free the trapped dog as it was already breathing very feebly after possibly being trapped for 24 hours. When they got the poor fellow out of the mud, he couldn't walk, so they carried him back to the house. Back home with his owner, George Niskanen, Ed began his slow restoration-a happy ending to a dangerous adventure. George was thankful to the bachelor party heroes.

Now, the people of Carver, Minnesota, have new heroes to cheer for. Indeed, this incredible act of bravery and compassion redefined the meaning of a bachelor party. It became a heroic tale of humanity, friendship, and the instinct（本能）to do what's right.

Rebecka Peterson, a high school math teacher, is the nation's 2023 Teacher of the Year. Her first year of teaching wasn't without its 1 ，but she remembered why she was there and wanted to bear those2 thoughts in mind. So she 3 the One Good Thing blog.

It was 4 and fun, really. Every evening, she would write on her blog, 5 "one good thing she experienced that day. She gave her blog the tagline; "Every day may not be good, but there is on good thing in every day."

She encouraged her 6 to do the same in their handwritten journals. Just a few minutes a day to7 something good that happened—that would be enough, she 8 . She believes that it will make them happier and more 9 to learn.

During her eleven years in teaching, Peterson has10 that some students find math difficult. But her efforts to make it 11 made her the 2023 Oklahoma Teacher of the Year. From there, she made the 12 to win the nation's 2023 Teacher of the Year.

Peterson has travelled around the country, talking to teaches about binging 13 back to Classrooms. Her goals include emphasizing the positive experiences students have not only with math but with learning 14 . She hopes her stories will attract new teachers to the profession and give 15 to current ones.

I had a terrible experience last year. One night my younger brother, Chase, was driving us home from our weekly cleaning of the church. We were both getting 1 , so we picked up a couple of energy drinks at a gas station. Then we jumped onto the freeway and 2 home.

The ride was fine. My brother was focused, so I 3 my eyes. I woke up when we were close to our exit. But the car 4 turned to the right. I did not care at first because Chase often played jokes. Then I 5 it was not a joke at all.

I shouted my brother's name at the top of my 6 . He woke up from his sleep in time to slam on the brakes, though the brakes did little to 7 us down. We crashed into a streetlight, 8 us hit the dirt hill of the off-ramp (出口匝道).

Then I 9 something white and bright shoot toward my chest. It hit me and left me breathless but 10 me from the dashboard (仪表盘). The streetlight swung around, hitting two other 11 and then crashed back onto the hood of our car. One inch 12 to us, Chase and I wouldn't be here today. A kind man 13 us out of our car, and the policeman came to 14 us. They said there were no broken ribs (肋骨) and no internal bleeding.

Our dad 15 on the scene in his car and drove us home. From that day on, we never drove while we were sleepy or tired again.
