倒装句就是将正常的陈述语序加以变化，主要作用是强调被提前的部分。倒装句可分为全部倒装和部分倒装两种：
一、全部倒装
谓语动词提前至主语之前为全部倒装，如：
Out came his guest.
There lived an elderly lady whose husband died long ago.
On the hill stood a little cottage that contained heaps of hay.
二、部分倒装
助动词或情态动词提至主语之前，谓语动词位置不变，即为部分倒装，如：
So little did I know about him that I was easily taken in by his words.
Doesn't her invitation appeal to you?
Neither could he see through your plan.
