"I was attacked by a tiger shark in October 1997. It was near my home on the island of Kanai. The waves were really good, so nothing was stopping us."That was until large shark came right up under Mike and 1 his teeth into Mike's lower leg. There'd been no splashing, no noise, and Mike felt no pain, only intense pressure on his 2 body.

As he tried to get himself free, the shark bit down harder, shaking its head back and forth and tossing Mike around like a doll. Mike hit the shark hard in the face, again and again until the shark 3 him. As Mike swam back into shore, he felt his lower right leg spamming(痉挛); when he looked down, he realized it was 4. The shark had bit his lower leg off. Mike's friends came to his aid immediately, and tried to control severe bleeding and rushed him to the hospital.

When Mike opened his eyes, he realized he was in the hospital.

During the next few weeks, Mike researched prosthetics (假肢) and considered the 5.

As soon as Mike was given the OK by his doctors, he did what many of us might consider 6: he started riding the waves again. In fact, his first time back was near the site of his attack. But Mike was unshaken. Instead, he was curious-why was he attacked? Mike 7 that the water had a fishy smell the morning of the attack. Was that what attracted the shark?

His curiosity led him to research sharks, and while he never8 why he became a target, Mike did learn something that would change his life: Humans are far more 9 to sharks than the other way around, Mike tells Reader's Digest. "I watched a documentary called Sharkwater, and I learned about the 10for shark fin soup and the fact that 70 million sharks a year are killed for their fins alone."

His unique situation as a shark survivor empowered him to give sharks a 11, Mike says. He began working with the Hawaii state legislature (立法机关)to help pass a 12 on shark-related products." I partnered with other like-minded shark attack survivors and marine biologists, and we headed to Washington to urge the government to create a nationwide bill protecting sharks."

With the completion of the Human Genome(基因组)Project more than 20 years ago, and the discovery of the double helix structure of DNA enjoying its 70th birthday last year, you might assume that we know how life works. Think again!

Evolution has a 4bn-year head start on us. However, several aspects of the standard picture of how life works-the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular(分子)machines and more-have wildly reduced the complexity of life. 

In the excellent book How Life Works, Philip Ball explorers the new biology, revealing life to be a far richer, more delicate affair than we have understood. Ball explains that life is a system of many levels-genes, proteins, cells, tissues, and body modules-each with its own rules and principles, so there is no unique place to look for an answer to it. 

Also, How Life Works is a much more appealing title than the overused question of "What is life?". We should be less concerned with what a thing is, and rather more focused on what a thing does. Defining a living thing implies an unchangeable ideal type, but this will run counter to the Darwinian principle that living things are four-dimensional, ever changing in time as well as space.

But it's an idea that is deeply rooted within our culture. Ball points out that we rely on metaphors(比喻)to explain and explore the complexities of life, but none suffice. We are taught that cells are machines, though no machine we have invented behaves like the simplest cell; that DNA is a code or a blueprint, though it is neither; that the brain is a computer, though no computer behaves like a brain at all.

Ball is a terrific writer, pumping out books on incredibly diverse subjects. There's a wealth of well-researched information in here, and some details that are a bit chewy for the lay reader. But the book serves as an essential introduction on our never-ending quest to understand life.

The very unusual series of events finished as Sondrup was heading home from an extended work shift. She had just completed her fourth continuous night shift, and 1 was coming over her. Little did she know that July 26, 2023, would become a day unforgettable in her 2 .

While driving home, Sondrup 3 a truck had overturned on State Route 143 near Sky Harbour, with a man 4 inside. Despite her tiredness, she made an inspiration—of-the-moment decision to help.

"It's 5 , but there were so many reasons that led me to that fine moment," recalled Sondrup. "6 , I wouldn't have been there."

Under what she described as a turn of fate (命运), Sondrup 7 , joined by a couple of other individuals who happened to be passing by. With unquestionable timing, no other cars were on the road, allowing her to cross over safely and reach the 8 scene.

Sondrup courageously 9 under the truck to check the injured man. In an act of 10 , she used a bystander's belt as a makeshi ft tourniquet (止血带) to stop the bleeding. Months have passed since that fateful day, and on October 18, the Phoenix Fire Department 11 Sondrup for her life-saving actions.

"I really feel that my guiding 12 led me to that very moment," she told Fox 10Phoenix. "I'm not without imperfections, but I believe that at that 13 moment, I received a guiding premonition (预感)."

 The man Sondrup rescued recently reached out to express his 14 for the second chance at life. "I wish him nothing but the best," Sondrup said. "I hope he experiences a new 15 and a future filled with success."

In early 2021, I hit a rut in my studies. Although I had been productive early in my graduate career, my long hours and hard work were no longer translating into success in the laboratory, and I felt hopeless about achieving my goals.

As I began to search for the cause of my struggles, I became increasingly aware that my "quiet time" at the lab bench was anything but. Instead of thinking about science, I was watching television or interacting with social media on my smartphone. Although I could mask this inefficiency (低效率) with longer hours, my work felt disorganized. Through reflection, I came to understand my problem.

To make a change, I reduced my connectivity by using a basic mobile phone without an Internet connection during work hours, and removing unnecessary apps from my smartphone when I did use it. Things didn't go smoothly in the beginning, but with time, I started reading papers during long experiments, and began a habit of writing in my down time. These practices have already made success: I am currently preparing a review article for publication with my adviser. I have also felt more engaged in meetings – coming better prepared, asking questions and taking hand-written notes. Perhaps most importantly, I have felt my anxiety about work efficiency disappear and that my disorganized work-life relationship is traded for one with clearer boundaries.

Changing my smartphone habits has also created challenges. Not all my friends have been supportive of my reduced connectivity, and I have missed messages on communication services. Yet these problems have been a small price to pay for increased productivity. So if you find yourself in this situation, I encourage you to build down time and uninterrupted study into your schedule, which could be significant for your success.

One sunny afternoon in the park, I witnessed a remarkable scene. An elderly gentleman was standing by the side of a path, looking confused and lost. Just at that moment, a kind- hearted young girl approached him. She asked him gently what was wrong and listened patiently as he struggled to explain.

Without hesitation, the girl took his hand and slowly guided him along the path, chatting with him to ease his anxiety. They walked together until they reached the place the old man was supposed to be. The old man smiled with thankfulness and relief.

After helping the old man, the girl didn't just leave. She spent some more time with him, sharing some interesting stories and making him laugh. The old man's eyes sparkled with joy, and it was clear that this interaction had brightened his day. The girl's kindness seemed to have an effect, as other people in the park also noticed and were inspired by her actions.

I continued to observe as the girl then decided to stay with the old man for a while longer. They sat on a bench together, and the girl began to tell him about her own life, her dreams, and her adventures. The old man listened attentively, nodding and smiling from time to time. It was a beautiful sight to behold, this unlikely pair sharing such a genuine and heartwarming connection.

This encounter made me reflect on the importance of kindness in our society. In a world that can often seem cold and hurried, acts like the girl's are like the tower of light, showing us the way to a more empathetic(同情的)and caring existence. It also made me think about how we all have the potential to make a difference in someone else's life, no matter how small the act may be.

Now, whenever I recall this scene, it warms my heart and reminds me to be more willing to offer a helping hand, to spread kindness wherever I go, and to believe in the goodness that lies within each of us.
