本app提供了真人朗读功能，详情页有【原文】【翻译】【导读】【解析】【经典解读】【哲理引申】等专题模块《大学》是一篇论述儒家修身齐家治国平天下思想的散文，原是《小戴礼记》第四十二篇，相传为春秋战国时期曾子所作，实为秦汉时儒家作品，是一部中国古代讨论教育理论的重要著作。经北宋程颢、程颐竭力尊崇，南宋朱熹又作《大学章句》，最终和《中庸》《论语》《孟子》并称“四书”。宋、元以后，《大学》成为学校官定的教科书和科举考试的必读书，对中国古代教育产生了极大的影响。《大学》提出的“三纲领”（明明德、亲民、止于至善）和“八条目”（格物、致知、诚意、正心、修身、齐家、治国、平天下），强调修己是治人的前提，修己的目的是为了治国平天下，说明治国平天下和个人道德修养的一致性。
