A  bad begining makes a bad ending .

恶始有恶终

A friend in need is a friend indeed

 患难见真情

A good name is easier lost than won

美名难得而易失

A little learning is a dangerous thing

一知半解是危险的事

A rolling stone gathers no moss

流石不生苔

 A wise man thinks all that he say, a fool says all that he thinks

 聪明的人一切想了再说，愚蠢的人想的一切都说出来

A still tongue makes a wise head 

智者寡言

A candle lights others and consumes itself

蜡烛照亮了别人，毁灭了自己

A penny saved is a penny gained 

省一文就等于挣一文

A sound mind is a sound body

有健康的体魄才有健全的精神

A true friend is one soul in two bodies .

挚友同心

A liar is not believed eventhough  he tells the truth

说谎的人即使说了真话也没人相信
