Science short stories read by first-grade pupils.
Socrates, an ancient Greek philosopher, not only wrote brilliant works, but also recruited students to lag behind and inspired the wisdom of young people with inspirational talks. Whenever people admire his profound knowledge and superior wisdom, he always modestly says, "What I know is my own ignorance." Newton, known as the "father of mechanics", discovered the law of universal gravitation, and in heat, he determined the law of cooling. In mathematics, he put forward the "flow number method", established binomial theorem and Leibniz founded calculus almost at the same time, which opened a new era of mathematics. He is a great scientist who has made many achievements, yet he is very modest. Regarding his success, he said modestly, "If I see farther than Descartes, it is because I stand on the shoulders of giants." He also said to people, "I am like a child playing on the beach." Sometimes I am glad to find a smooth and beautiful stone, but the sea of truth has not been discovered. "
Beethoven, a world-famous music master, said modestly that he "learned only a few notes".
The great scientist Einstein said that he was "as naive as a child".
Andre, a French chemist, made great achievements in chemistry when he was a Muji. He was elected as a member of the Royal Society, Owens College set up a new professor position in organic chemistry for him, and Glass University elected him as an honorary doctor. These honors didn't change his modesty at all.
After the death of George W. Laima, Engels called him "the most modest man in the world" in his eulogy.

Spring is coming, and the peach trees are covered with green leaves and beautiful flowers. The little peach tree said, "I don't know who helped me loosen the soil and let my leaves grow so well and flowers bloom so beautifully." A little butterfly comes, and the little peach tree says, "Thank you, little butterfly. Did you help me loosen the soil? "
The little butterfly said, no, no, "I can't loosen the soil, I can only spread pollen." Goodbye, butterfly. Goodbye, Peachtree.
A little bee came, and the little peach tree said, "Thank you, little bee. Did you help me loosen the soil? "
The little bee said, no, no, "I can't loosen the soil, I can only collect honey." Bye, bee. Goodbye, Peachtree.
A woodpecker came and the little peach tree said, "Thank you, Woodpecker. Did you help me loosen the soil? "
Woodpecker said: no, no, "I can't loosen the soil, I can only catch pests." Goodbye woodpecker, goodbye peach tree.
An elephant came slowly, and the little peach tree said, "Thank you, elephant. Did you help me loosen the soil? "

The little peach tree said, "thank you, little earthworm." It turned out that you helped me loosen the soil. "
Earthworms whispered, "You're welcome, you're welcome. This is what I should do. " After that, the little earthworm wriggled and slowly got into the soil.

Fleming is a British scientist and the discoverer of penicillin. When Fleming was a military doctor, he saw many soldiers die painfully because of bacterial infection in wounds. He was determined to find a medicine to treat diseases caused by bacteria. He found penicillin in the experiment. This magical medicine has saved countless lives, which is the success of his efforts with several scientists. Fleming won the Nobel Prize in Medicine. He said: "Opportunities are only reserved for prepared minds. Litmus test paper was invented by the great scientist Boyle.
In an intense experiment, violets in the laboratory were splashed with concentrated hydrochloric acid. Boyle, who loves flowers, washed the smoking violets with water and put them in a vase. After a while, Boyle found that purple turned red. This strange phenomenon prompted him to carry out many experiments on the interaction between flowers and trees and acid and alkali. He found that most flowers and plants can change color under the action of acid or alkali, among which the purple extract extracted from litmus lichen is the most obvious, which turns red in acid and blue in alkali. Taking advantage of this feature, Boyle soaked the paper with litmus extract, and then dried it to make litmus test paper commonly used in experiments. This accidental experiment led to Boyle's invention.

James Hargreaves, the inventor of Jenny's textile machine, is an ordinary worker. He can both weave and be a carpenter. My wife Jenny is a kind and diligent textile expert. She is greedy from morning till night, but she never turns much. Every time Hager Rivaz sees his wife nervous and tired, he always wants to improve this old spinning wheel. One day, he accidentally knocked over the spinning wheel at home. He saw that the hammer that had been placed horizontally had become vertical and kept turning. The accident inspired him: since the spindle can still rotate when it is upright, can't several yarns be spun at the same time if several upright spindles are used side by side? He set out to make a new eight-spindle loom and named it "Jenny loom". This invention is dozens of times more efficient than the old textile machine and is regarded by Engels as "the first invention to fundamentally change the situation of British workers".

Hua Tuo was a great physician and pharmacologist at the end of the Eastern Han Dynasty in China, and made great contributions to enriching the ancient medical treasure house of China. Hua Tuo is not only proficient in medical skills, but also attaches great importance to the health care function of physical exercise. Once, while studying in the study, Hua Tuo saw a child swinging the latch back and forth. He immediately thought of the old book "A family is not slow, running water is not rotten." Why don't people exercise every day like this and let the blood flow? Later, referring to "Introduction" (a method of overall physical exercise), Warren sorted out a set of boxing methods for physical exercise, which was called "Five Birds Play". This kind of exercise is a gymnastics that imitates the movements of five animals, such as tigers, deer, bears, apes and birds, and can stretch the joints, back, waist and limbs of the whole body.
Hua Tuo's disciple, Wu Pu, has been doing "Five Birds Show" for decades and has lived to be over 90 years old. He still has light steps, bright ears and strong teeth. From this, we can see that "Wuqinxi" is an effective fitness gymnastics.
