Books are very important to human beings. They let us enter the civilized era, learn knowledge and make our technology change with each passing day. In other words, life without books is like the earth without sunshine. Wisdom without books is better than a bird without wings.
People have many metaphors for books: books are ladder books for human progress, treasure houses for storing knowledge and nutrients for the whole world. As long as we are willing to learn, we will learn the essence of thousands of years of human wisdom. Newton loved reading and studying the things of his predecessors since he was a child. On the basis of studying predecessors' works, he discovered the law of gravity of the earth and became a great scientist.
