1. Puncture on the Leg During the Warring States Period, Su Qin studied day and night. When he was too tired, he stabbed his leg with an awl to clear his mind; Sun Jing in the Han Dynasty used an awl to prevent drowsiness while studying. The rope tied his hair to the beam, and he would be woken up whenever he fell asleep. This is the story of "thorns hanging on the beam" in history.
Che Yin, Sun Kang, and Kuang Heng of the Jin Dynasty who cut through walls to steal money, their families were all so poor that they couldn't even afford oil for lighting lamps. On summer evenings, Che Yin made a small bag with gauze, caught some fireflies and put it in it, and read with the light emitted by the fireflies; Sun Kang sat in the snow on a cold winter night, using the reflection of the snow to read hard; Kuang Heng I cut a small hole in the wall and "stole" some light from my neighbor's house to read. The idioms "The firefly reflects the snow" and "The wall is cut to steal the light" tell these stories.
Wang Xizhi, the great calligrapher of the Eastern Jin Dynasty, practiced calligraphy hard since he was a child. Every time he finished writing, he would go to the pond in front of his house to wash his brush. Over time, the pool of clear water turned into a pool of ink. Later, people called this pond "Mochi". Through diligent study and practice, Wang Xizhi finally became a famous calligrapher and was known as the "Sage of Calligraphy".
2. Helen Keller has a book. Have you read it? The name of this book is "The Story of Diligence and Study". This book records the stories of many famous people studying hard. Let me tell you about one of them: Helen Keller. I believe everyone knows it, right? She is a famous female writer in the United States. She suffered a serious illness when she was a child, which made her blind and lost her hearing. When Helen was seven years old, her parents hired a teacher to help her learn. But Helen couldn’t see or hear, so how could she learn? So the teacher thought of a way: first give her a doll to play with, and then write the word doll on the palm of her hand, so that Helen would know what a doll is. Therefore, Helen quickly fell in love with this method of learning. From then on, Helen used this method to learn. She memorized words one by one. Over time, she learned a lot of words. You can think about it, as a deaf and blind child, what difficulties did Helen have to overcome? But she was not afraid of difficulties, studied and lived with amazing perseverance, and finally became a world-famous writer. Nowadays, people's living and learning conditions are much better. There is no need to "cut through walls to steal light", let alone imitate the practice of "thorns and hanging beams", but the diligent and studious spirit of the ancients is worth learning from, and we are all healthy People are much better than Helen Keller. As long as we learn not to be afraid of difficulties, don’t give up halfway, study hard, and are determined to become talented, we will definitely succeed.
3. Edison is a famous inventor in the world. He has more than a thousand inventions, such as the electric light, the phonograph, and the movie player. However, in his childhood, Edison only went to school for a few years because of his poor family. When he was twelve years old, he went to sell newspapers on the train. Unable to go to school to study, he studied on his own. He loves learning very much. He reads books and newspapers while selling newspapers, and seizes the time to study and do experiments. Edison's father was usually very strict with his family. He stipulated that the whole family must turn off the lights and go to bed before 11:30 every night. However, Edison often returned home at eleven o'clock in the evening after selling newspapers, so he had no time to do his favorite experiments after returning home. How could this work? This was simply unbearable for Edison, who liked to learn and explore on his own. So he thought about it and finally came up with a good way to get his father to support his experiment. One day, Edison used copper wire to set up a wire on a tree and connected it directly to his good friend's house. He left the remaining newspapers and a telegraph machine at his friend's house. After arriving home in the evening, his father wanted to read the newspaper. Edison said that today's newspaper was sold out. At first his father was not very sorry. In order to arouse his father's interest, Edison began to talk about how fresh and interesting the content of today's newspaper was. It was a pity that he did not read it. Edison's father really wanted to read it when he heard him talk so vividly. So he asked Edison if he could still find a way to get one. Edison said that his friend Belle also had a copy, and he could send the contents of the newspaper over by telegraph. At this time, Edison's father became addicted to reading newspapers, so he readily agreed to it.
4. "Joule seeks knowledge - loves to learn" The famous British scientist Joule loved physics since he was a child. He often did some experiments on electricity and heat by himself. One year during the holidays, Joule and his brother traveled to the countryside together.
The smart and studious Joule did not forget to do his physics experiments even when he was playing. He found a lame horse, held by his brother, and quietly hid behind it. He used a Voda battery to pass current to the horse, hoping to test the animal's reaction after being stimulated by the current. As a result, the reaction he wanted to see appeared. After receiving the electric shock, the horse jumped wildly and almost kicked his brother. Although danger has emerged, this has not affected the mood of Xiao Joule, who loves to experiment, at all. He and Giulia rowed a boat to a lake surrounded by mountains, where Joule wanted to test how big the echo was. They filled their muskets with gunpowder and pulled the triggers. Unexpectedly, with a "bang", a long flame spurted out from the muzzle of the gun, burning Joule's eyebrows, and almost scared his brother into falling into the lake. At this time, the sky was covered with thick clouds, and there was lightning and thunder. Joule, who was just about to go ashore to hide from the rain, found that every time the lightning passed, he could hear the rumble of thunder for a long time. What was going on? Joule didn't care about hiding from the rain, so he pulled his brother up a hill and carefully recorded the time between each lightning and thunder with his pocket watch. After school started, Joule couldn't wait to tell the teacher all the experiments he had done and asked the teacher for advice.
The teacher looked at the studious and inquiring Joule and smiled, and patiently explained to him: "The propagation speeds of light and sound are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning before hearing it. The thunder and lightning actually happened at the same time." Joule suddenly understood. From then on, he became more obsessed with learning scientific knowledge. Through continuous learning and careful observation and calculation, he finally discovered the thermal work equivalent and the law of conservation of energy, and became an outstanding scientist.
5. "Overcome the Disabled Barreni - Persistence" Barreni became disabled due to illness when she was a child. Her mother's heart was like a knife, but she still held back her grief. She thought that what the child needed most now was encouragement and help, not the mother's tears. The mother came to Barreni's hospital bed, held his hand and said: "Son, mother believes that you are an ambitious person, and I hope you can use your own legs to walk bravely on the road of life! Good job!" Reni, can you promise mom?" His mother's words hit Barreni's heart like a hammer. He cried "Wow" and threw himself into his mother's arms. From then on, whenever her mother had free time, she would practice walking and gymnastics for Barreni, and she was often so exhausted that she was sweating profusely. One time, my mother caught a bad cold. She thought that mothers should not only teach through words, but also teach by example. Despite having a high fever, she got out of bed and helped Barreni practice walking as planned. Bean-like sweat dripped down her mother's face. She wiped it with a dry towel, gritted her teeth, and helped Barreni complete the day's exercise plan. Physical exercise compensates for the inconvenience caused by his disability. The role of his mother's example deeply educated Barreni, and he finally withstood the harsh blow given to him by fate. He studies hard and his academic performance is always among the best in the class. Finally, he was admitted to the Medical College of the University of Vienna with excellent results. After graduating from university, Barreni devoted all his energy to the research of otological neurology. Finally, he finally got on the podium of the Nobel Prize in Physiology and Medicine.
