默不作声 hold one's tongue; keep silence; keep quiet [silent]; keep a calm sough; keep mum; refrain from comment; abstain from speaking; (as) mute as a fish
Other sound than the owl s voice there was none , save the falling of a fountain into its stone basin ; for , it was one of those dark nights that hold their breath by the hour together , and then heave a long low sigh , and hold their breath again 枭啼之外只有喷泉飞溅到石盆里的沙沙声因为那是个一连几小时屏息不作声,然后发出一声低低的长叹,又再屏息不作声的黑夜。
