近年来，UKiset考试越来越火爆。每一项的得分都显得非常重要。我们今天来聊一聊UKiset语法知识点：倒装句。
为了强调、突出（作用）等语意目的而颠倒原有语序的句式叫做倒装句。在倒装句中，颠倒了的成分可以恢复原位而句意基本不变，句法成分不变。
分类：
部分倒装：只将位于句中的be动词、助动词或情态动词置于主语之前，叫作部分倒装。
全部倒装：主语和谓语完全颠倒过来，叫作全部倒装（完全倒装）。
在具体的考察情况中，部分倒装的考察概率相比要大于全部倒装，那么今天，我们就来说说需要部分倒装的几种最常见的情况。
一、“儿子”打头半倒装
我们知道“儿子”的英文是SON，这三个字母分别代表了以下三种情况：
1.S——So/Such+修饰成分，放在句首
So loudly did he speak that even people inthe next room could hear him.
Such a nice man did he seem that we allbelieve him.
注：so还可以表示“也”
I saw the film. So did she.她也是。
2.O——Only+状语，放在句首
Only then did I realize theimportance of math. (副词)
Only when the war was over in1918 was he able to get happily back to work. (从句)
注:如果only后面不是状语，则不用倒装
Only Wang Ling knows this.
3.N——否定词/半否定词，放在句首
①简单句中：这类词或短语主要有
never, neither, nor, little, seldom, rarely, in no way, at no time,few, not, no等。
Not a word did I say to him.
Never have I found him so happy.
Little does he care about what I said.
I can’t swim. Neither can he.
②并列句中：
Neither…nor…既不..也不…,两个分句都倒装
“Not only+分句,but also+分句”句型中的前一分句要部分倒装
Neither do I know what has happened, nor doI care about it.
Not only does John love Chinese, he is alsogood at speaking it.
注：not only...but also...连接主语时,不倒装。
Not only the mother but also the childrenare sick.
③时间状从：
hardly/ scarcely…when…；
no sooner…than… 一…就…
(=as soon as不倒装)
（只表示过去发生的事情，主句为过去完成时，从句为过去时，如hardly或no sooner位于句首时语气强，而且主句的谓语要用部分倒装）
No sooner had he gone to bed than he fellasleep.
Hardly/Scarcely had he gone to bed when hefell asleep.
注：Not until连用放在句首，从句不倒装，主句倒装
Not until last week did theyfind the lost bike. (简单句)
Not until my son had enteredthe university did he realize the importance of time. (复合句)
二、虚拟if可退场
在虚拟结构中，条件状语从句的谓语含有were, had和should这三个词时，可省去if，将这些词移至主语之前。
Had I time (= If I had time), I would go and help you.
Were I you (= If I were you), I would go abroad.
Should he come (=If he should come), tell him to ring me up.
