Jenna, a popular girl from Westwood Middle School, had graduated first in her class and was ready for new1 in high school.

However, high school was different. In the first week, Jenna went to tryouts{#blank#}1{#/blank#}(选拔赛) for cheerleaders{#blank#}2{#/blank#}(啦啦队队员). She was competing against very talented girls, and she knew it would be2 for her to be selected. Two hours later, the3 read a list of the girls for a second tryout. Her heart was down as the list ended without her name. Feeling4 , she walked home carrying her schoolbag full of homework.

Arriving home, she started with maths. She had always been a5 maths student, but now she was struggling. She moved on to English and history, and was happy to find that she didn't have any trouble with those subjects. Feeling better, she decided not to6 maths for the time being.

The next day Jenna went to see Mrs Biden about being on the school7 . Mrs Biden wasn't as8 as Jenna. "I'm sorry, but we have enough9 for the newspaper already. Come back next year and we'll talk then." Jenna smiled10 and left. "Why is high school so11 ?" she sighed.

Later in maths class, Jenna devoted herself to figuring out the problems that had given her so much12 . By the end of class, she understood how to get them right. As she gathered her books, Jenna decided she'd continue to try to fit in at her new school. She wasn't sure if she'd13 , but she knew she had to try. High school was just as her mum had said, "You will feel like a small fish in a big pond14 a big fish in a small pond. The challenge is to become the15 fish you can be."

Omar Vazquez grew up in poverty on Mexico's Yucatan peninsula. He watched his single mother struggle to put food on the table, and today the memory inspires him to help those in need. When an invasive (入侵的) seaweed called sargassum showed up on Mexico's Caribbean beaches, Omar looked past the matter of it all and saw an opportunity to help others.

Sargassum is not dangerous, but it has an unpleasant smell and can become so thick that it keeps people from entering the water. Mexico has experienced record-setting amounts of the seaweed in recent years, and it has made its way to Florida's beaches as well. Experts say there could be as much as 100 tons of sargassum blocking Mexican shorelines in 2023.

With tourism dollars at risk, officials and locals alike were eager to remove the seaweed, but only Omar saw its true potential. The professional gardener organized a beach cleanup that provided jobs for about 300 local families, but he knew there was more to do. Since people's attitude towards the seaweed reminded him of his own life experiences, he decided to become an agent (推动者) for change.

When sargassum started arriving, everyone was complaining. "I wanted to make something good out of something everyone saw as bad," Omar explained.

In 2018, Omar found a way to turn sargassum into building blocks that he calls Sargablock. He creates these blocks by mixing 40% sargassum with other materials like clay, then putting them in a block-forming machine and baking them in the sun for days. The end result is an organic, sustainable, and ecologically friendly building material that experts say could last for 120 years.

To date, Omar's company, Bluegreen Mexico, has used 700 tons of sargassum to build low-income housing for those in need. Omar said he would take on more projects, and donate more houses to single mothers like his own mom.

In a heartwarming tale from Georgia, a 72-year-old senior recently celebrated his college graduation in cinema studies, an achievement made even more special by the presence of his proud 99-year-old mother.

Sam Kaplan of Lawrenceville decided to start on his educational journey at Georgia Gwinnett College in 2019, half a century after he had firstly chosen not to get higher education following his high school graduation in 1969. The catalyst for his return to academia came when he heard a radio announcement about a degree programme in cinema studies.

Recalling that moment, Kaplan said, "I was driving down the highway when I heard about the degree programme. The next exit led to Collinsville, so I immediately exited, and within five minutes, I was enrolling in classes. I've always had a passion for writing and storytelling. I longed to transform my narratives into screenplays, but I realized I needed the basic knowledge to do so,"

Kaplan admitted that the journey was a mix of anxiety and excitement, but it proved to be greatly rewarding. He graduated with a 3.975 grade point average and perfect grade honours, majoring in cinema and media arts, and had desires to continue creating screenplays in the future.

"It was an exciting and nerve-wracking (神经紧张的) challenge. Re-recognizing myself with the art of studying and communicating with fellow students was a lot of fun," he told FOX5 Atlanta.

The most heartwarming thing of Kaplan's graduation day was the presence of his mother, 99-year-old Virginia Kaplan, during the ceremony. Virginia expressed her huge pride, saying, "I am so proud of him. He faced numerous challenges but insisted, and I am delighted, pleased, and extremely proud," the mother also added. "With his new degree, he's going to stand out in whatever he does. Who knows, I might even make an appearance in the movies."

While taking a 20-hour train ride along the edge of the Taklimakan Desert in northwestern China, I had the kind of humbling, educational, and above all else, wonderful1 with a local that all travelers long for. A young Chinese man 2 me on the train. My3 friend spoke virtually no English, so I happily took the4 to practice my Chinese.

Over several hours he would tell me about how he had5 a two-year professional school to quickly find a job 6 highways in order to help support his family. Perhaps most7 .however, was the fact that this man spent hours studying every day after hard physical labor. Without batting an eye he would8 a translated Emerson passage before asking about the literary influence of American9 as a whole. "And what do you all learn about Russian authors?" I10 hi m asking at one point.

It would have been easy to11 my assumptions about this highway builder who had never been more than a few hundred miles from home. But this highly informed,12 , and admirable person prevented me doing so. In the course of a couple of hours, he13 me just how much one can gain from14 with an open mind, and a willingness to15 with locals from all walks of life.

On a recent Wednesday, archaeologists announced a groundbreaking discovery that challenges our understanding of early human capabilities. They have unearthed what is believed to be the oldest wooden structure ever found, dating back nearly half a million years. This discovery at Kalambo Falls in northern Zambia, near the border with Tanzania, suggests that our ancestors were more technologically advanced than previously thought.

The wooden structure, which is exceptionally well-preserved, dates back at least 476,000 years. This timeline predates the emergence of Homo sapiens, as detailed in a study published in the journal Nature. The wood shows evidence of having been cut and shaped using stone tools, indicating a level of craftsmanship that was not previously attributed to these early humans.

The structure, which is thought to have functioned as a walkway or platform elevated above the seasonally wet ground, demonstrates a purposeful construction technique. A collection of wooden tools, including a wedge and a digging stick, were also found at the site, further supporting the idea of a developed woodworking tradition.

Larry Barham, an archaeologist at the University of Liverpool and the lead author of the study, described the structure as involving "the intentional shaping of two trees to create a framework of two interlocking supports." A notch was cut into one log, and another tree was shaped to fit through this notch, providing stability to the structure.

The use of wood by early humans was already known, but it was typically associated with basic tasks such as starting fires or hunting. However, the discovery at Kalambo Falls indicates a more sophisticated application of woodworking skills. Barham explained, "The structure involves the intentional shaping of two trees to create a framework of two interlocking supports," which required a level of planning and execution that suggests a higher cognitive ability.

The preservation of the wooden structure is remarkable, given that wood typically decays over time, leaving little trace for archaeologists to study. The high water levels at Kalambo Falls are believed to have played a crucial role in preserving the structure for centuries.

These findings from Kalambo Falls not only provide evidence of an early human ability to manipulate their environment but also suggest a more complex cognitive capacity among these early humans than what has been inferred from stone tools alone. Barham concluded, "The finds from Kalambo Falls indicate that these earlier humans, like Homo sapiens, had the capacity to alter their surroundings, creating a built environment." This discovery underscores the need to reassess our understanding of early human technological and cognitive development.

I was sitting at my desk when another graduate student in my lab approached me. "Can you help?" he asked. His experiment wasn't working and he desperately needed help. I was then a fifth year PhD student, and I took pride in being the senior member of the lab, whom everyone looked up to. But that also meant I was the one everyone turned to for help — which ate away bours, days, and sometimes weeks that I could have spent on my own research.

There were many reasons I had a hard time saying no to such pleas (恳求). I was new to the United States for graduate school. I found it difficult to make new friends and discover activities I enjoyed. So I spent a huge chank of my time in the lab, with my lab-mates serving as my primary source of social connection. I feared that if I turned down their requests, I'd lose their favor.

But the extra responsibilities came at a cost. I had to work extra hours to catch up with my own work, and I often made sacrifices to my personal life.

It wasn't until my wife gave birth to our first child that I realized how thin I had stretched myself and how misguided my priorities(优先次序) were. While she lay in a hospital bed in the early stages of labor, I sat nearby hunched(伏首前倾的) over my laptop finishing up a work report. Hours later, after hearing my daughter's first cry and watching her tiny fingers grab tightly onto mine, it dawned on me: I should have been fully present during my daughter's birth. I was clearly spending too much time working if my job had intruded(侵入) into one of the most precious moments of my life.

From then on ,I decided to spend more time with my family by declining extra assignments and carefully considering each request for help. I still enjoyed collaborating with others, but I prioritized mutually beneficial tasks or those my manager asked me to take on, rather than accepting everything that came my way.

I noticed many benefits: no longer working overtime and improved work performance. I was also pleased to discover that "Sorry , I'd love to help but I have a deadline coming up" is an acceptable response to a request for assistance.

It's hard to say "no " to those you work with. But I've learned that sometimes that's the best course of action to avoid an excessive workload and lead a freer and happier life.
