倒装句是英语中常见的用法，意在说明被倒转部分的重要性，某些时候也起到强调作用或起到惊叹作用。英语倒装句可分为部分倒转和完全倒转，两种倒装句的用法大庭相径。
用法一：表示方向、地点和时间的副词、介词短语置于句首用完全倒装。这种用法的倒转句，常见于口语对话中，英语书面语种较少出现这种用法。例句：here comes the bus(车到这来了)，在这个例句中，主语“the bus”被后置，这就是为了强调车“来”的这一动作。
用法二：表语+连系动词+主语(表语是形容词、介词短语、动词ing形式、过去分词等)。这种用法的完全倒装句可用于口头表达，也可用于书面表达。例句：such are the facts ,no one can deny them(这就是事实，没有人可以否认)，该例句强调事实的重要性。
倒装句,就是主语谓语位置是颠倒的句子.一般句子,主语在谓语前；倒装句,谓语在主语前.
具体情况如下：
1. “某些副词+不及物动词+主语”的句式,需要全部倒装.常用的副词主要有：here , there , now , then , out , in , down , up , away 等,表示强调.主语是代词时,不必倒装.
Out rushed the boy .
Down came the brown wave .
2. 表示方位的短语放在句首,后面一般使用倒装语序.
West of the lake lies the famous city .
3. There be + 主语+地点.其中动词be也可以是其他词,如lie,stand等.
There are many different kinds of mooncakes on the table .
There in Greece lived a famous thinker , named Aristotle .
4. 如果直接引语后注明是什么人说的,而且主语是名词时,需要完全倒装；主语是代词时,一般不用倒装.
“Let”s go ! ”said the captain .
“Take off your boots !” ordered the guard .
5. 为了保持句子平衡,或为了强调表语或状语,或使上下文紧密衔接时.
They arrived at an old church , in front of which stood a big crowd of people .
6. 用于so开头的句子,表示重复前面相同的内容,意为“也怎么样”.另外,在结果状语从句句型so …that …中,如果强调so…放在句首,主句需要部分倒装.
I often go out for a walk after supper . So does she .
我经常在晚饭后出去散步,她也这样.
So excited was she at the news that she couldn”t say a word .
听到这个消息,她是如此激动,以致于一句话也说不出来.
7. 用于nor , neither 开头的句子,表示重复前面相同的内容,“也不怎么样”.
Li Lei can”t answer the question . Neither can I .

8. only放在句首,强调状语（副词,介词短语或状语从句等）,全句语序要部分倒装.

注意：only放在句首,强调主语时,语序不必倒装.
