一般來說，倒裝分為全部倒裝和部分倒裝，有的倒裝是因為語法需要而出現的，有的倒裝則是因為結構平衡的需要而出現的。
一、完全倒裝（主謂倒裝）是指把謂語全部提到主語的前面。 例：In a lecture hall of a university in England sits a professor.
1.以here, there，now, then引導的句子，要完全倒裝。這種句子中的謂語動詞通常是不及物動詞。
如：Here comes the train! / There goes the bell!
注意：若代詞作主語，只把該副詞提前主謂語序不變。Here he comes . / Here it is .
2句首是擬聲詞或 out , in , up ,away , down 等副詞，句子要完全倒裝。（注意，這時句子的主語也必須是名詞。如果是人稱代詞，也不能使用倒裝結構。） 如：Up went the rocket. /Up it went.
3. 介詞短語作狀語在句首，句子要完全倒裝。注意，這時句子的謂語動詞通常是不及物動詞。
如：In the front of the lecture hall sat the speaker.
4.表語置于句首，且主語較長或結構較復雜的句子要用全部倒裝。如：Gone are the days when we ha nothing to eat.
5.so/ neither/ nor 表前面所說的情況也適合于后者，其倒裝結構為“so/ neither/ nor+助動詞/系動詞/情態動詞”，這里的主語同前一個句子的主語指的是同一人或物。如：She has finished her homework, so has her brother.
She hasn’t gone there, neither/ nor has he.
二、部分倒裝（助動詞倒裝）是指把謂語的一部分（助動詞）提到主語的前面。 例： Never in my life have I seen such a thing.
1.用于疑問句中。如：How did you do that? Did you see the film yesterday?
2. if 從句中如有 were ( had , should ) , if 省去后，要部分倒裝,把were，had，should提到主語前面。如：
If you had come yesterday, you would have seen him.
---Had you come yesterday, you would have seen him.
3.as 引導的讓步狀語從句，要部分倒裝（表語、狀語倒裝）。有以下幾種形式：
1） 副詞置于句首。如：Much as I like it (=Although I like it very much), I will not buy it.
2） 動詞置于句首。如：Wait as you may (= Although you may wait), he will not see you.
3） 形容詞或名詞置于句首。如：Proud as the nobles are (=Although the nobles are proud), they are afraid to see me.
Child as he is (=Although he is a child), he can tell right from wrong.
注意：如果名詞前有形容詞修飾時，as引導的倒裝句中要保留不定冠詞。如：
A bad-tempered man as he is (=Although he is a bad-tempered man), he loves me deeply.
4.句首為否定詞或否定意義的詞語時，句子要部分倒裝�！ �( not , not only , never , little , seldom , not until, hardly ( scarcely ) , no sooner, not once, at no time,... )
Little do we know about him.
No sooner had he closed his eyes than he fell asleep.
Seldom does he come back on Sundays.
Not until he came back did I know about it.
5.only 在句首引導狀語，或not until 引導的狀語在句首，主句要部分倒裝。如：
Only then did I realize the important of English. / Only when a child grows up does he understand his parents’ intentions.
但若only修飾的是句子的其它成分，則無需倒裝。如：Only socialism can save China. (only修飾句子的主語，仍用正常語序)
6.not only ... but also ... 引導兩個并列句，前倒后不倒。如：
Not only does he do well in his lessons, but also he often helps others with their lessons.
7.在以often, well, many a time, now and again等方式或頻度副詞(短語)開頭的句子中,要用部分倒裝結構
Many a time has John given me good advice. / Often have we made that test.
8. 用于某些表示祝愿的句子里。May you succeed!
9. so或so引導的短語放在句首,要部分倒裝。
So loudly did he speak that even people in the next room could hear him.
so…that結構中的倒裝。有時要強調so 所修飾的形容詞或副詞，常將so連同它所修飾的形容詞或副詞一起提到句首。這時，主句要用倒裝結構。如：
He runs so fast that he is far ahead of others.---So fast does he run that he is far ahead of others.
He is so clever that he can work out all the difficult problems in the book.
--So clever is he that he can work out all the difficult problems in the book.(全部倒裝)
10.狀語位于句首表示強調或使句子平衡，或使上下文緊密銜接，句子要部分倒裝。
倒裝句的用法
1 . 在以 here , there , in , out , up , down , away , back , now , then 等副詞開頭的句子里，如果主語是名詞，常用全部倒裝。
Out rushed the boys . /Then followed three days of heavy rain .
若代詞作主語，只把該副詞提前主謂語序不變。Here he comes . / Here it is .
2 . 當句首狀語是表示地點的介詞詞組時，也常常引起全部倒裝。 South of the city lies a big steel factory .
3 . 以帶有否定意義而且修飾全句的詞開頭的句子，要用“部分倒裝”語序 ( 倒裝的方法跟變一般疑問句的方法相似 ) 。這類常見詞有 never , hardly , seldom , not , not only , not until ( 引導從句時，主句“部分倒裝” ) ，little , rarely , no sooner . . . than , hardly . . . when , scarcely . . . when。 例:Never shall I do this again .
其中 no sooner . . . than , hardly . . . when , scarcely . . . when 表示“一……就……”的意思。no sooner , hardly , scarcely 引出的主句要用“部分倒裝”形式的過去完成時，than , when 引出的從句用過去時。
No sooner had I got home than it began to rain .
如果帶有否定意義的詞不是修飾全句，只是修飾主語，那么句子的主謂不必倒裝。
Scarcely a sound came from among the crowd .
4 . so 修飾形容詞或副詞，only 修飾副詞或狀語放在句首時“部分倒裝”。
So badly was he injured in the accident that he was sent to the hospital for treatment . /Only in this way can you master English .
如果 only 修飾主語，句子則不倒裝。 例如:Only Wang Lin knows this .
5. neither , nor 或 no more 放在句首，作“也不”講時，所引導的句子部分倒裝。He can’ t answer the question . Neither can I .
6.為了保持句子平衡或為了強調表語或狀語，或使上下文緊密銜接時，需倒裝。
Gone are the days when we used foreign oil .
7.由 as , though ( although ) 引導的表示“雖然”，“盡管”的讓步狀語從句，用倒裝語序，即把從句中的表語或狀語等放在 as 的前面。
