      英语中的基本语序是“主语+谓语”，这叫陈述句语序。如果将谓语的全部或一部分放在主语之前，这种语序叫做倒装语序.当谓语动词全部放在主语之前时，叫做全部倒装.当谓语的一部分放在主语之前时，叫做部分倒装.倒装的使用有以下即中情形:
1.用于句首为下列副词的句子中: here, there, now, out ,in, up, down, away, off, then, 形成全部倒装.
Here is a ticket for you.
Down came the bird.
(Here you are. There he comes.为什么这两个句子没有用倒装的形式呢?因为它们的主语是代词，而只有主语是名词或名词短语的时候，才适用于这种全部倒装。)

2.在下列副词为首的句型中, 形成部分倒装.only + 浮词、介词短语，壮语从句或often , many a time.如：
only then did I realize the importance of English.
often did we ask her not to be late for school.
Many a time has he helped us.

3.用在前面所说的情况也适合于另一个人或物的肯定句或否定句中.
(1)肯定重复倒装用，so 如;
He likes swimming,so do I.
(2)否定重复倒装用 nor,neither,no more.
I don’t agree with you, nor do they.
Tom can’t speak English. Neither can Jack.

4.在下列否定副词或短语为首的句子中，形成部分倒装
never, at no time , by no means , nowhere. in no case. Little,. in no circumstances. not only, neither, nor, no sooner…than , never before, not until, hardly, scarcely, barely. 如：
No sooner had I gone out than it rained.

5.用于让步庄于从句中，用no matter how,however, as.
如：Young as he is, he is good at painting very much.
