1. 否定型倒装
在正式文体中，如果将never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意义的副词若位于句首，则其后的句子要用部分倒装。如：
后来我再也没见到过他了。
I never saw him again.
Never did I see him again.
他很少出去吃饭。
He seldom goes out for dinner.
Seldom does he go out for dinner.
她几乎没时间听音乐。
She hardly has time to listen to music.
Hardly does she have time to listen to music.
他几乎没有认识到他面临的危险。
He little realized the danger he faced.
Little did he realize the danger he faced.
对于notuntil句型，当not until位于句首时，其后的主句要用倒装语序。如：
雨停了之后他才离开这房间。
He didnt leave the room until the rain stopped.
