古時英國常有狼群四處覓食,襲擊人畜,所以,在英國人眼中,狼往往是饑餓的象征,比如說have a wolf inone's stomach(肚裏有狼)是指“饑腸轆轆”,have a wolfish appetite是“有狼壹般的食欲”,to wolf down one's food是“狼吞虎咽的吃東西”。Keep thewolf from the door,當然就是“得免饑寒”的意思了。
例如:We were in those days very poor,and keeping the wolff rom the door proved no easy tas。那時,我們很窮,求溫飽很不容易。
