The favorable reason for opening the book (150 words) is known speed.

Gorky said: "Books are the ladder of human progress." Reading more books will increase your knowledge and broaden your horizons. Chairman Mao must be familiar with the art of war to establish a new China. Bacon, a world famous person, said: "History lessons make people wise, poetry makes them wise, mathematics makes them careful, natural history makes them profound, and the study of ethics makes them solemn." Many of these meanings can be summed up in one sentence: opening books is beneficial. If we don't read more books, how can we get so much knowledge? Without knowledge, how can you tell people who is right and who is wrong? Books are the summary of historical experience and the crystallization of social culture. Reading can thoroughly understand the truth of life; Reading can help you understand the vicissitudes of the world; Reading can benefit people all over the world. If you don't read more books, where can you get rich words to write compositions? Marx learned a lot from opening books. When he wrote Das Kapital, he read more than 1000 books by himself and went to the British Museum to read three books. If Marx had never read a book, he might not have written Das Kapital. The ancients said that a person can't go without eating meat for a day, nor can he go without reading for a day. Books are the nourishment of people all over the world, which makes us strong, progressive and strong-willed. As long as we pay attention to eye hygiene, watch green every half hour and think while watching, it will not only hurt our eyes, but also make us healthier. Therefore, reading won't hurt your eyes. If we buy books from regular bookstores, we won't be unhealthy. The first lesson in our Chinese book was written by Chairman Mao. Because he also likes reading, he has such a good literary talent. We play computer games. There are many words in the game. We need to understand them by reading! If you don't study, you will think of some beggars in the street. If you don't study, you will end up homeless. The ancients said, "Opening books is beneficial." Indeed, reading widely can make people knowledgeable, eloquent and respected. Du Fu, an ancient poet, famously said, "Reading is like breaking thousands of volumes, and writing is like a god." This is undeniable. Du Fu has read countless books. Although many books have been turned over and torn by him, the knowledge in them has been deeply imprinted in his mind. When he wrote articles and poems, a string of good words and sentences flowed down from the pen tip, and one excellent poem after another was passed down from generation to generation. Therefore, reading more useful books can help us write good articles. Books are the nourishment of human beings and the source of human knowledge. Just as a civilized country has lost its book culture, this once prosperous country will also face the threat of extinction. Therefore, people can never live without books. Opening books is beneficial, but not beneficial. Those who don't read are unsuccessful, and those who read are immortal. So it is beneficial to open books.
