1、全部倒装
（1）here, there, now, then, thus等副词置于句首,谓语动词常用be, come, go, lie, run等表示来去或状态的动词。例如：
Then came the bus. Here is your letter.
（2）表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。
Out rushed a boy。
Ahead sat an old woman.
但如果主语是人称代词，不能要倒装，比如：Here you are. Away they went.
2、部分倒装
（1） 句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。
Never have I seen such a performance.
Not until the child fell asleep did the mother leave the room.
当Not until引出主从复合句，主句倒装，从句不倒装。注意： 如否定词不在句首不倒装。比如：I have never seen such a performance.
The mother?didnt?leave the room until the child fell asleep.
（2）否定词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than等，要倒装。例如：
Not only did he refuse the gift, he also severely criticized the sender.
Hardly had she gone out when a student came to visit her.
No sooner had she gone out than a student came to visit her.
（3）so, neither, nor作部分倒装
用这些词表示也、也不 的句子要部分倒装。例如：
Tom can speak French. So can Jack.
If you wont go, neither will I.
（4）only+ 副词/介词/状语从句位于句首，要部分倒装
only in this way, can you learn English well.
only after being asked three times did he come to the meeting.
如果句子为主从复合句，则主句倒装，从句不倒装。
only when he is seriously ill does he ever stay in bed.
