If you wake up early, you'll likely hear birds singing. This "dawn chorus(黎明合唱)" starts around 4 am and lasts for hours. Scientists explain this behavior with three main reasons.
Birds sing to find mates(配偶) and protect their homes. Morning light is poor, making it hard to find food like insects. Instead of moving around, they use this time to communicate through song. Another reason is to show strength. By singing loudly, they prove they survived the night—a dangerous time in nature—and become more attractive as mates.
Cooler morning air helps their songs travel more clearly. Stable(稳定的) air conditions reduce noise, allowing their unique calls to be easily recognized. While people once thought morning sounds carried farther due to less wind, a 2003 study found the distance wasn't greater. However, the clarity improved because cooler temperatures make air denser, helping sound waves stay focused.
Since birds need to save energy, singing when they're most likely to be heard makes sense. Early mornings provide ideal conditions for their "performances", ensuring their messages reach others effectively. This behavior shows how animals adapt (适应) to their environment using simple yet effective strategies. Observing the dawn chorus connects us to nature's rhythms(节奏). It reminds us that even simple actions like waking up a bit earlier can reveal the hidden strategies animals use to thrive.

Wu Xiong, a 41-year-old headmaster, has spent about 20 years turning a small mountain school into a lively sports and education center.
In 2004, he became the headmaster of Tangfang Primary School in Guizhou. At that time, the school was old and small with only 3 teachers and 75 students. Many children didn't like going to school. To solve this problem, Wu decided to use sports.
In 2006, the school held its first sports meeting. Teachers and students carried heavy cement slab(水泥板) from 1. 5 kilometers away. They used wooden boards as nets for a table tennis competition. Later, they added badminton and other events. Students loved these activities.
When the school got more money from the government in 2009, it became a boarding school (寄宿学校). Wu felt that sports were even more important for students' free time. Now the school is over 10 times bigger than before. It has 42 teachers and nearly 500 students. There are 4 PE teachers. Students do sports for at least 2. 5 hours every day. Among the 469 students, only 6 wear glasses. Through sports competitions, they learned how to face both winning and losing. The school's average scores(平均分) rose from below 30 points in 2004 to over 80 in 2023. More than 100 graduates have gone to middle schools that focus on sports.
Wu says the school must balance sports and study. Students must finish homework first, but doing sports they enjoy helps everyone.
