3 . Humans spend approximately one-third of their lives sleeping, which means that by the time you reach 15 years old, you will have slept for about 5 years! However, the question remains: why do we do it? Sleep has long been a puzzle for people, leading scientists to explore its mysteries. They have found that during sleep, our brains and bodies do not simply shut down; instead, complex processes unfold.

What causes sleepiness? It’s caused by our biological clock releasing a special chemical signal at the same time daily, signaling it’’s time to wind down. The feeling of heaviness comes from the buildup of old nerve messenger chemicals. When the message gets too much, the brain senses that it’s time to sleep. During sleep, the body breaks down and clears away these old messengers, preparing for a fresh start.

As you slip into sleep, your heart and breathing slow down, and your brain ignores the most sounds and surroundings around you. Despite appearances, your brain remains active during sleep, performing essential tasks. Throughout the night, you cycle through light, deep, and REM (rapid eye movement) sleep stages every 90 minutes. Early on, slow-wave sleep is the primary stage, aiding in brain cleaning, while towards morning,REM sleep increases, leading to vivid dreams. During sleep, your body repairs and grows, creating new skin, muscle, and other tissues with released chemicals. It’s also a time for hormone (荷尔蒙) production, aiding growth, and boosting the immune (免疫) system to fight infections.

Scientists still have many questions about sleep, such as why some people need more sleep than others and how certain animals can function with less sleep. They aim to find ways to improve sleep quality. However, one thing is clear: getting enough sleep is vital for health and intelligence. Think of sleep as a free magic potion that strengthens you, aids growth, boosts immunity, and enhances intelligence, happiness, and creativity. Simply lie down and rest to enjoy these benefits.

4 . Frederick Phiri, known as the junk-art king of Zambia, set out on a remarkable journey at the age of 22 when he began earning an international reputation for being able to make complex and elegant sculptures from deserted metal found in his community.

Phiri’s path to artistic recognition was filled with challenges. His childhood was marked by the loss of his father and his mother leaving him behind, making him under the care of his grandfather. While his grandfather provided for his basic education, Phiri faced financial struggles when he entered secondary school, forcing him to take on various jobs to fund his studies. Yet, despite these obstacles, his passion for art remained growing, and he dedicated his free time to drawing and crafting in the classroom.

Upon completing his education, Phiri sought to support himself by creating wire animal sculptures (雕塑品), which he sold to tourists. It was during this period that his exceptional talent caught the attention of Karen Beattie, the director of Project Luangwa, a nonprofit organization committed to education and economic development in central Africa.

Teaming up with local welder (焊接工) Moses Mbewe in 2017, Phiri contributed to the creation of a complex set of doors for Project Luangwa during the rainy season. Impressed by his work, Beattie presented Phiri with a challenge: to create art from abandoned waste metal. Undiscouraged, Phiri embraced the opportunity, transforming forgotten keys, broken bike chains, and old metal bottles into attracting abstract animal sculptures, including elephants, cranes, giraffes, and monkeys.

Today, Phiri’s artistic pursuits continue to flourish as he transforms deserted junk into striking sculptures showcased at the Project Luangwa headquarters. His talent has earned recognition and admiration from the community, fueling his dreams of pursuing formal art education at the Evelyn Hone College in Lusaka and creating even more magnificent sculptures in the future. Through creativity and determination, Phiri has turned adversity (逆境) into artistic success, leaving a lasting impact on Zambia’s art scene.

5 . In a groundbreaking achievement, a rhino has successfully undergone embryo (胚胎) transfer, marking the first successful use of a method that holds promise for saving the nearly extinct northern white rhino subspecies.

The experiment, conducted with the less endangered southern white rhino subspecies, involved creating an embryo in a lab using eggs and sperm (精子) collected from other rhinos. This embryo was then transferred into a southern white rhino alternative mother in Kenya. Despite the unfortunate death of the alternative mother due to an infection in November 2023, researchers praised the successful embryo transfer and pregnancy (怀孕) as a proof of concept. They are now ready to proceed to the next stage of the project: transferring northern white rhinoembryos.

Professor Thomas Hildebrandt expressed optimism about the findings, highlighting the significance of the successful embryo transfer in demonstrating that frozen and defrosted embryos produced in a lab can survive. This development offers hope for the revival of the northern white rhino population.

However, challenges facing rhino conservation remain significant. While the southern white rhino subspecies and the black rhino species have shown signs of recovery from population declines due to illegal hunting for their horns (牛角), the northern white rhino subspecies is on the edge of extinction. With only two known members left in the world, Najin and her daughter Fatu, both unable to reproduce naturally, and the recent death of the last male white rhino, Sudan, in 2018, urgent action is needed to prevent the extinction of this subspecies. Dr. Jo Shaw, CEO of Save the Rhino International, emphasized the importance of addressing the primary threats facing rhinos worldwide: illegal hunting for their horns and habitat loss due to development. She stressed the need to provide rhinos with the space and security they need to succeed in their natural environment.

While the successful embryo transfer representsa significant advancement in rhino conservation efforts, organized action is required to address the main challenges facing rhino populations worldwide.

1. What is the purpose of the experiment mentioned in the text?

A．To evaluate the efficiency of a new rhino birth program.

10 . Not much trash and almost no plastic actually gets recycled. About a third of U.S. garbage gets recycled, according to the Environmental Protection Agency’s most recent estimate. The rest goes to landfills, which release greenhouse gases into the atmosphere and pollute their surroundings.

To make recycling easier, many U.S. cities don’t ask Americans to separate paper, glass, metal and plastic. ‘They just ask people to put anything recyclable into one bin and let waste plants do the sorting. But waste plants don’t catch everything. AI is now an essential tool for the world’s waste management leaders. Greyparrot, a tech company has already installed more than l00 AI trash spotters in about 50 sorting facilities.

Greyparrot’s device is, basically, a set of visual and infrared (红外线的) cameras hooked up to a computer, which monitors trash as it passes by on a conveyor belt and labels it under 70 categories, from loose bottle caps to books to aluminum cans. Waste plants could connect these AI systems to sorting robots to help them separate trash from recyclables more accurately. They could also use the AI as a quality control system to measure how well they’re sorting trash from recyclables. That could help plant managers adjust their production lines to cover more recyclables, or cheek that a bundle of recyclables is free of pollutants, which would allow them to sell at a higher price.

In the next few years, some recycling companies plan to retrofit (改良) thousands of material- recovery facilities with Al trash - spotting tools. Of these companies, Bollegraaf has built thousands of these facilities, including 340 in North America, accounting for a majority of the recovery plants in the world.

The trash-spotting computers could one day help regulators punish companies that produce tsunamis of non - recyclable packaging because the AI systems are so accurate that they can identify the brands on individual items. Putting the AI tools in thousands of waste plants can raise recycling percentage. If the needle can be moved by even 5 to 10 percent, that would be a phenomenal outcome for greenhouse gas emissions and environmental impact.
