一.概念:
英语句子通常有两种语序:一种主语在前,谓语在后,称为自然语序,另一种谓语在前,主语在后,称为倒装语序。
二.相关知识点精讲
按“主语+ 谓语” 这种顺序排列的句子是陈述语序。如果排列顺序变为“谓语（ 或谓语一部分）+主语”，就是倒装。倒装句分为：
完全倒装： 整个谓语移至主语前面叫完全倒装。
部分倒装： 只把助动词、系动词或情态动词放在主语之前叫部分倒装。
1. 当以there, here, out , in , up , down, away 等副词开头的句子，为了起到强调的作用，可构成倒装句，只把副词放在句首，主语和谓语位置调换，不加助动词。
Our teacher came in.
In came our teacher.
这种倒装要求：主语必须是名词。主语是人称代词时，主语和谓语语序不变。
Here it is.
Away he went.
这类倒装句式一般只用一般现在时和一般过去时。
Here comes the bus.
Out rushed the boys.
2. how, then, just, often 表示时间的副词放在句首，可构成倒装句，只把副词放在句首，主语和谓语位置调换，不加助动词。
Then came 8 years of the Anti Japanese War.
3. 表地点状语的介词短语放在句首，要用倒装句式，以示强调。
这种倒装句也是主谓直接调换位置，不加助动词did, does或do.
Under a big tree ________, half asleep.
A. did sat a fat man B. a fat man sat
C. did a fat man sat D. sat a fat man
4. there放在句首时，要用倒装句式。
在“there + be”结构中的谓语动词有时不用be , 而用表示类似“存在”观念的其他不及物动词。如：live, stand, come, lie, flow, enter, rise 和appear等。
There came shouts for help from the river.
There lies a large wheat field in front of the house.
Many years ago there lived an old man in the wooden house.
In front of the tower flews a stream.
5. so + 动词+主语
neither/ nor + 动词+主语
表示两人的同样一个情况时，只能表示一件事，即上、下句所使用的动词、时态要一致。
否则要用so it is with…
You can ride a bike. So can I .
He has been to Beijing. So have I .
The first one isn’t good, neither is the second.
His uncle is a worker and has been working in the factory for more than ten years. So it is with his aunt.
