How to learn in life

Kuang Heng in Han Dynasty was very studious as a teenager. As his family is poor, he has to do a lot of work during the day to earn money. Only at night can he sit down and read. However, he can't afford candles, so he can't read when it is dark. Kuang Heng was heartbroken at this time-wasting behavior, and his heart was very painful. His neighbor's family is very rich. At night, light candles in several rooms to make them bright. One day, Kuang Heng summoned up his courage and said to his neighbor, "I want to study at night, but I can't afford candles. Can I borrow an inch of your house? " Neighbors have always looked down on people who are poorer than their family, so they said viciously and sarcastically, "Since you are too poor to buy candles, what books are you reading?" Kuang Heng was very angry, but he decided to read the book well. When Kuang Heng came home, he quietly cut a small hole in the wall, through which the neighbor's candlelight came in. With this faint light, he eagerly began to read books and gradually finished reading all the books at home. After reading these books, Kuang Heng felt that his knowledge was far from enough, and his desire to continue reading more books was even more urgent. There is a big family nearby with many books. One day, Kuang Heng rolled up his bedding and appeared in front of a big house. He said to his host, "please take me in, and I will work for you at home for free." Just let me read all your books. " The host was moved by his spirit and agreed to his request to borrow books. This is how Kuang Heng studied diligently. Later, he became the prime minister of the Han and Yuan emperors and became a famous scholar in the Western Han Dynasty. [Last sentence] This fable describes two things that Kuang Heng did when he was a teenager, one was stealing light from the wall, and the other was borrowing books to study hard. He praised Kuang Heng's spirit of bravely overcoming difficulties and studying hard. Set a good example for us to study hard. ——————————————— Ba Jin's reading method The famous writer Ba Jin's reading method is very strange, because he did it without a book. Reading without books is really a miracle of the world. What's going on here? Ba Jin said: "I was hospitalized for the second time. After taking a nap for less than an hour every day, I get out of bed and sit on the small sofa, waiting for the nurse to take my temperature at two o'clock. I sat still, but I didn't doze off. My brain won't rest. It is recalling some books and works I have read in the past, as if it wants to keep some beautiful things before my memory completely declines. " It turns out that his reading method is to sit there and recall the books he has read. This has many advantages: (1) is not restricted by conditions and can make full use of time. Ba Jin cited two examples: one was that during the Great Patriotic War of the Soviet Union, Leningrad was surrounded by the Germans for a long time, and a young girl wrote such sentences as "So-and-so, Anna karenin" in her diary. There was no electricity and no candles, and the whole city was out of power. Instead of reading, she sat quietly in the dark, recalling the plot in the book. Tolstoy's novels helped her through those terrible nights. Another example is his own personal experience of ten years of civil strife. He said: "If the rebels allowed me to keep a diary during the Cultural Revolution and allowed me to keep a diary according to my own wishes, my diary must be full of titles. People will wonder: my study has been blocked for ten years. Where can I find those books to read? They forget that there is a big warehouse in people's hearts, which stores things that others can't take away. " These two examples show that you can "read" without normal reading conditions. (2) Review the past and learn new things. Through memory, take out the books you have read in the past and chew them bit by bit, just like cattle ruminating, which can be further digested and absorbed. Every time I recall, I will have a new understanding, a new understanding and a new harvest. (3) Be able to continuously draw spiritual strength from the books you have read. Ba Jin said: "I am now struggling with my illness, and all kinds of works are inspiring me ... Even if I don't have the spirit to read new works during my illness, the spiritual wealth accumulated in the past is enough for my limited rest of my life. People need light and heat until they die. " _ _ _ _ _ _ _ _ _ _ _ _ _-Gu read "Every man is responsible for the rise and fall of the world. This famous saying was first put forward by Gu, a patriotic thinker and famous scholar in the late Ming and early Qing Dynasties. Gu studied hard since he was a child. Enlightened at the age of 6, 10 began to read history books and literary masterpieces. 1 1 years old, his grandfather Li asked him to finish the History as a Mirror, and warned: "Now some people just browse the outline and other books to save trouble, thinking that everything is fine. I don't think this is worth taking. These words made Gu realize that reading and studying is an honest thing and must be treated seriously and faithfully. Gu Qin was diligent in reading, and he adopted the measures of "self-examination reading": First, he set himself the number of volumes that must be read every day; Secondly, he limited himself to copying the books he finished reading every day. After he finished reading Purple Tongzhi Sword, one book became two books. Third, ask yourself to take notes and write down your experiences every time you read a book. Some of his reading notes were later incorporated into the famous book Rizhilu; Finally, every spring and autumn, he will review the books he read in the first half of the year, read them silently, and ask people to read them aloud. If differences are found, he will check them immediately. He stipulated that he would spend 200 pages a day like this and never rest until he finished reviewing. -How does Chairman Mao read? Special hobbies For decades, Chairman Mao has been very busy, but he always takes time, even every minute, to study. His former residence in Zhongnanhai is a sea of books. Books are everywhere on the bookcase, desk, dining table and coffee table in the bedroom. All the beds are occupied by books except the place where one person lies. In order to study, Chairman Mao spent all available time. A few minutes before swimming, I sometimes have to read some famous poems. After swimming, I forgot to rest, so I picked up the book again. He never wastes even a few minutes in the toilet. The book Selected Works of Zhaoming, the second edition of Song Xichun, and some other books and periodicals were completed intermittently by this time. Read a little today and a little tomorrow. Chairman Mao often goes to boxes and books when he goes out for meetings or inspections. The train shook and bumped on the way, and he completely ignored it. He always keeps reading with a magnifying glass in one hand and a page in the other. In other places, like Beijing, there are books on the bed, desk, coffee table and dining table, which seem to be free. Although Chairman Mao was seriously ill in his later years, he still insisted on studying. He reread a set of hardcover Complete Works of Lu Xun and many other books and periodicals published before liberation and brought to Beijing from Yan 'an. On one occasion, Chairman Mao had a fever of over 39 degrees, and the doctor forbade him to read books. He said sadly, I have loved reading all my life, and now you don't let me study, and you make me lie here all day eating and sleeping. You know how hard it is for me! The staff had to put the books they had taken next to him, and he smiled happily. Study hard and read again and again. Chairman Mao has never opposed the reading method that only emphasizes books, and Chairman Mao has never opposed the reading method that only emphasizes quick results and does not emphasize results. When he read the complete works of Han Changli's poems, except for a few chapters, he carefully pondered and studied them one by one, from vocabulary, sentence reading, chapters to the meaning of the whole text. He can recite most of Han Ji's poems fluently through repeated reading and reciting. He read novels such as Journey to the West, Dream of Red Mansions, Outlaws of the Marsh and Romance of the Three Kingdoms in primary school and reread them in the 1960s. He has seen more than ten different versions of A Dream of Red Mansions. He read a book "Selected Works of Zhaoming" when he was at school. He read it in 1950s and 1960s, and read it several times in 1970s. There are three versions of his annotations. He has read many books on Marxism-Leninism and philosophy. He has read Li Da's History of the United Front and Outline of Sociology for ten times each. He has studied Manifesto of the Productive Party, Das Kapital, Selected Works of Lenin and so on. Many chapters and paragraphs are also annotated and crossed. For decades, every time Chairman Mao read a book or an article, he drew circles, bars, dots and other symbols in important places, and wrote a lot of comments in the eyebrows and blanks. Some also put books and articles%

Life needs to learn composition.

Is it life? Are we going to spend our lives in a hurry? So what should we do in a hurry? How can we make life without regrets? What do we need? Yes, that is, study, study and study again. Learning is a constant topic since ancient times. Without the knowledge of learning, there is no guidance to lead life to set sail. Without the motivation to learn, there is only ignorance and confusion left, so life needs to learn and get the flash of life from learning. Think about China from primitive society to this era of advanced science and technology, from scratch, from poverty and backwardness to national prosperity. What is the power to make the motherland stand for five thousand years? Yes, people are constantly learning, and only with the knowledge gained from learning can they create and develop. The development of a country is inseparable from the people, and the cognition of the people is inseparable from learning. This is a truth. Learning is like the ladder of life, it is a step-by-step process, and we will never stop climbing. There have always been many famous people who know how to learn and master knowledge, so that they have made amazing achievements. Henry Ford, a famous American automobile manufacturer, once said: When a person stops studying, he is old! Whether you are 30 or 80. If you don't stop studying, you can stay young. The important thing in life is to keep young. So study hard and stay young! Learning is an essential condiment in life. When you feel bored and have no future, try this seasoning. It can help you increase more knowledge, make you realize how wonderful learning is and make you enjoy it. There is a saying in The Analects of Confucius: It's a pleasure to learn from time to time. Only by studying can you feel happy and full in your life. There is such a famous person, who is a household name. He is the famous American inventor "Edison". Poor from a small family, I dropped out of primary school after only three months of schooling. In class, his mother is often called to school to talk to the teacher. This is because Edison often asks some questions that the teacher thinks are strange. The teacher thinks he is a mentally retarded child. So mom decided to teach Al herself. Edison was curious about many things since he was a child, and he liked to try it himself until he understood the truth. He was immersed in his fiery scientific experiments all his life, and he obtained 1093 patents. It is his diligence in self-study, his spirit of studying and inventing, and his thoughtful attitude that can make him become the "king of invention" from an imbecile in the eyes of others. He once said: Genius is one percent inspiration and ninety-nine percent perspiration. Yes, this 99% sweat is the process of his continuous learning. His learning process is not only sweat but also happiness, and there are such amazing achievements. This is Edison's life. It can be said that he spent his whole life in scientific experiments, and he spent his whole life studying and researching. Life without knowledge is terrible, and the age without knowledge is ignorant, so let's insert the wings of knowledge into life, learn to change our destiny, and learn to be rich and powerful. Let you shoulder the mission of learning and create greater glories. Without learning, there will be no progress, without progress, there will be no development, and life needs learning and continuous learning. Need to make a single spark start a prairie fire again.
