一、 倒装句之全部倒装
  全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和 一般过去时。常见的结构有:
  1)here,there,now,then,thus等副词置于句首,谓语动词常用be,come,go,lie,run.
  There goes the bell.
  Then came the chairman.
  Here is your letter.
  2)表示运动方向的副词或地点状语置于句首,谓语表示运动的动词。
  Out rushed a missile from under the bomber.

  注意:上述全部倒装的句型结构的主语必须是名词,如果主语是人称代词则不能完全倒装。例如:Here he comes. Away they went.
二、倒装句之部分倒装
  部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前。
  1)句首为否定或半否定的词语,如no,not,never,seldom,little,hardly,at no time,in no way,not until… 等。
  Never have I seen such a performance.
  Nowhere will you find the answer to this question.
  Not until the child fell asleep did the mother leave the room.
  当Not until引出主从复合句,主句倒装,从句不倒装。
  注意:如否定词不在句首不倒装。
  I have never seen such a performance.
  The mother didn‘t leave the room until the child fell asleep.
