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：

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not…until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 didn’t leave the room until the rain stopped.

→Not until the rain stopped did he leave the room.

某些起副词作用的介词短语，由于含有否定词，若位于句首，其后要用部分倒装。如：

In [Under] no circumstances will I lend money to him.无论如何我也不会再借钱给他了。
