1. Helen Keller
When Helen Keller was born for nineteen months, she lost her precious hearing and sight due to illness, so she became a severely disabled child who was deaf, dumb and blind. She can't study and live like a normal person.
But with her own will, she challenged the disease again and again, overcame the unimaginable difficulties of ordinary people, entered the university, and graduated with excellent results. During my college years, I wrote the story of my life and became an excellent speaker.
Second, Pavlov.
Throughout his life, Pavlov regarded the struggle for science as his duty and responsibility, and was willing to be a "hard worker of science". When I was a child, Pavlov and his brother dug a pit for planting apple trees. This hole has been dug. When my father saw it, he said it was misplaced and dug it again. My brother put down his shovel and quit, but Pavlov ignored the blood bubbles on his hand and dug again until he dug a hole and planted an apple tree.
Later, Pavlov became a physiologist, studying dog conditioned reflex in the laboratory all day. He often uses his salary to buy experimental dogs. It takes four or five hours to dissect a dog. He counted the dog's saliva flowing out of the glass tube very carefully and recorded it in his notebook in detail.
A new assistant counted for a while and felt monotonous, but Pavlov solemnly said to him:
"If science needs it, count him ten or twenty years!" At the age of 87, Pavlov contracted hepatitis and later pneumonia, but he still worked as a "hard worker of science". He also feels very sorry that he has not fully fulfilled his obligations to mankind as a scientist.
Third, Edison
Edison's life is a life of "benefiting mankind" and fighting for it. Edison went to school for only three months and was completely self-taught. He works almost sixteen or seventeen hours a day. At the age of 30, he invented the phonograph, and at the age of 32, he invented the "light of the world"-the electric lamp. Every time Edison invented something, he had to go through a hard struggle.
Take the invention of electric light as an example. It took him nearly two years to work 20 hours a day, sometimes even two days without sleep. When he is tired, he will lie down in the laboratory for a while. The key to making electric lamps is to find a suitable material. Edison tried more than 1600 materials, and finally chose the carbon filament made of bamboo as the filament.
Edison devoted his whole life to science. He made more than 1000 inventions in his life. His obligation is to benefit mankind, which can be said to be truly fulfilled.
Fourth, Kuang Heng.
There was a man named Kuang Heng. His family was poor, so he couldn't afford candles and he couldn't study at night. Kuang Heng's neighbors light candles every night. He wanted to study in his neighbor's house, but he was turned down. Later, Kuang Heng came up with a good idea. He cut a small hole in the wall, and the light from his neighbor's house came in. He put the book in front of the lamp and began to read. Kuang Heng has read more and more books, but he has no money to buy books.
One day, he found that a talented master had a lot of books piled up at home, so he went to help the talented master and had no money. The genius master was very surprised and asked him, why are you busy in vain? Kuang Heng didn't hide anything, so he said, "I work for you, and I don't want to get paid. I just want to borrow your book. I wonder if you promise? " Only God was very happy, so he lent him books from home, and Kuang Heng became a learned man.
Five newtons
Newton likes to make mechanical models. A water clock he made was praised for its accurate timing. The way he plays ball is also very strange. One day, he made a lantern and hung it on the tail of a kite. When night falls, the lighted lanterns are lifted into the air by the power of kites. People were frightened and thought there was a comet. Nevertheless, he is often discriminated against because of his poor academic performance.
Once in class, a good student kicked Newton and called him an idiot. Newton was furious. He thought, why am I bullied by him? I must pass him! From then on, Newton studied hard. After studying hard, Newton's academic performance improved continuously, and he soon surpassed his classmates who had bullied him and was among the best.
