To kick down the ladder—— To forget favors

打掉梯子——过河拆桥

A flash in the pan——In like a lion,out like a lamb

平底锅里一闪亮——不了了之，虎头蛇尾

TO return to our sheep——To get down to brass tacks

再回到羊身上——言归正传，闲话少说

As poor as a church mouse——To be down and out

穷得像教堂里的老鼠——一贫如洗，家徒四壁

To hitch one's wagon to a star——To have a been in one's bonnet

把马车扔上星星——吃心妄想，白日做梦

As gentle as a lamb——To be nonplussed

像羊羔一般有礼——无言以对，悄声无息
