Actions speak louder than words. 事实胜于雄辩

A good book is a good friend. 好书如同挚友

A stitch in time saves nine. 未雨绸缪

A clean hand wants no washing. 身正不怕影子斜

A light heart lives long. 豁达者长寿

A friend in need is a friend indeed. 患难见真交

A road of a thousand miles begins with one step. 千里之行始于足下

All that glitters is not gold. 发光的不一定是金子

All things are difficult before they are easy. 万事开头难

All work and no play makes Jack a dull boy. 只会学习不玩耍，聪明孩子也变傻
