A mother‘s love never changes.母爱永恒。 

    An apple a day keeps the doctor away.一天一苹果，不用请医生。 

    A new broom sweeps clean.新官上任三把火。 

    An eye for an eye and a tooth for a tooth.以眼还眼，以牙还牙。 

    An hour in the morning is worth two in the evening.一日之计在于晨。 

    An old dog cannot learn new tricks.老狗学不出新把戏。 

    An ounce of luck is better than a pound of wisdom.聪明才智，不如运气。 

    An ounce of prevention is worth a pound of cure.预防为主，治疗为辅。 

    A rolling stone gathers no moss.滚石不生苔，转业不聚财。 

    As a man sows, so he shall reap.种瓜得瓜，种豆得豆。 

    A single flower does not make a spring.一花独放不是春百花齐放春满园。liuxuepaper.com
