人读书是为着有用，反之便是白白劳作。如牛一样，吃的是草，出的是力，挤的是奶，对人有益，才被饲养。读书像做人，各有各的活法。博览群书付诸笔墨，会成杂家，高谈阔论，也能成为谈资；专心致志苦钻精研的，可成为权威，在某个领域有所建树。唯有过目即忘的一类，图个凑热? People reading is useful, on the contrary is vain work. Like a cow, eating grass, out of force, crowded is milk, good for people, was reared. Reading like a man, each with its own living law. Book Fair reading brushstrokes, will be miscellaneous, talkative, but also become talkative; concentrate on research, can become the authority, in a field to accomplish something. Only a class that is a mere forgetting, figure a hot?
