1, books are the ladder of human progress. Comparing books to the ladder of human progress means that human progress cannot be separated from books, which provide a lot of knowledge and experience for human beings, so we must read more books and read them well.

This famous saying comes from Gorky's mouth. Books are the wealth created by all mankind in history, the best embodiment of human wisdom, will and ideals, the material carrier for human to express ideas, spread knowledge, accumulate culture and transmit experience, the treasure house for storing wisdom handed down from generation to generation, and the most important carrier and preservation method of human knowledge.

3. Books are necessary for human beings to climb new heights and pave the way for human progress. It's hard to imagine how human beings advanced to modern civilized society without books. Books enable us to open the treasure house of knowledge and gain more knowledge. The development of society and the progress of human civilization are inseparable from books. Great men in history passed on their thoughts and spirits to future generations through books.
