大体可把倒装句分为以下几种情况：
一． 全倒装
1． here,there,up,down,in ,out,away,off,now,then等表方向，时间的副词位于句首是，句子常用全倒装。这些句子的谓语动词常是come,go ,lie,live,stand,sit ,seem,remain 等不及物动词。这个结构不用进行时。There stand a tower by the lake.
Now comes your turn.
In he came and the lesson began.
2.当表示方位的介词短语放句首时，句子需全倒装。Under the table lies a wounded young man .
3.表语提到句首需用全倒装，这样往往是因为主语有较长修饰语。

4．直接引语位于句首时，句子需用全倒装 ，结构如：asked Mary,answered John,said the old lady等。但当主语是人称代词，需用正常语序。”What do you mean?”he asked.
二． 半倒装：
1． 否定意义副词nor,neither ,rarely,never,scarcely,little,hardly,seldom,at no time,by no means,in no way,on no accoune,nowhere,not until,no sooner …thanhardly…when,not only…but also,neither…nor及表示频度的副词：often ,once,many a time,now and then 放句首时，用半倒装。

2.only+状语放句首时，句子需半倒装。

3.so/as 表示“也“时，或so/such…that…的句子中，so 修饰形容词、副词或such修饰名词放句首时，句子需半倒装。

4.用于省略了if的非真实条件句。这类句子中有were,had,should等词时，把were,had ,should置于句首 。如：Were I you ,I would refuse to do it.
5.特殊形式的倒装。在as引导的让步状语从句中，要用倒装：
