按英语习惯,当never,hardly,seldom,little,few,not until,not,no,no sooner,by no means,under no circumstances等否定词置于句首时,其后要用部分倒装.如：
Never did I see him again.后来我再也没见到过他了.
Little did I dream that the girl was my niece.我做梦也没想到那女孩是我的侄女.
Seldom does he go out for dinner.他很少出去吃饭.
Hardly does she have time to listen to music.他几乎没时间听音乐.
No sooner had we reached the airport than the plane took off.我们刚到机场,飞机就起飞了.
Not until we lose our health do we realize its value.等到失去了健康,才明白它的价值.
No sooner had she agreed to marry him than she started to have terrible doubts.她刚同意嫁给他她就开始产生可怕的疑虑.
Under no circumstances are children allowed in the bar.在任何情况下也不能允许儿童进酒吧.
如果你是指no sooner ...than...和 hardly...when...的话 则no sooner和hardly 后倒装 且时态退一格 than 和 when后不到装
