英语句子有两种语序：自然语序和倒装语序。主语在谓语之前时，叫自然语序;如果把谓语动词放在主语前面，这就是倒装语序。倒装语序又可分为全部倒装和部分倒装。
全部倒装
Out rushed the student.
Here comes the No.9 bus.
部分倒装
Will you go to a show with me tonight?
Have you seen any good show lately?
用法：
1.用于疑问句
Do you need me now, professor?
2.用于以引导词there开头的固定倒装句型中
Long long ago, there lived in Hangzhou a girl called Aqiao.
3.用于以now, then, next, out, in, up, down, away, there, here等副词开头的句子里。
There goes your dinner.
4.含有否定意义的副词或连词，hardly, never, seldom, not, not only, little, no sooner than, not until等放在句首
No sooner had I started to type my paper than the telephone rang.
5.only所修饰的副词、介词短语或状语从句放在句首时
Only when that fails shall I leave the ship, but not before that, nor shall any of my crew.
6.副词so放在句首
He is a good student. So is Xiao Wu.
7.neither，nor放在句首
He can't see air. Nor can I, nor can you, nor can anybody.
8.虚拟结构中的条件从句省去if时，句中的were，had，should须移至主语之前。
例如：
Should you be prepared to reduce the price by 5%, we would place our order with you.
9.在某些让步从句里：
Come what may, I always stand by you.
Be it fine or not, I must go.
Young as she was, she did the work well.
10.在某些表示祝愿的句子里：
May you never forget me!
