部分倒裝：
1）句首為否定或半否定的詞語
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.
當Not until引出主從復合句，主句倒裝，從句不倒裝。注意：如否定詞不在句首不倒裝。比如：I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
2）否定詞開頭作部分倒裝
如 Not only…but also, Hardly/Scarcely…when, No sooner… than等，要倒裝。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作部分倒裝
用這些詞表示"也"、"也不" 的句子要部分倒裝。例如：
Tom can speak French. So can Jack.
If you won't go, neither will I.
4）only+副詞/介詞/狀語從句位于句首，要部分倒裝
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
如果句子為主從復合句，則主句倒裝，從句不倒裝。
Only when he is seriously ill does he ever stay in bed.
5）as，though引導的倒裝句
as/though引導的讓步從句必須將表語或狀語提前（形容詞，副詞，分詞，實義動詞提前）。但需注意：
1）句首名詞不能帶任何冠詞。
2）句首是實義動詞，其他助動詞放在主語后。如果實義動詞有賓語和狀語，隨實義動詞一起放在主語之前。例如：
Try hard as he will, he never seems able to do the work satisfactorily.
注意：讓步狀語從句中，有though，although時，后面的主句不能有but，但是though和yet可連用。
6)其他部分倒裝
1）so…that句型中的so 位于句首時，需倒裝。例如：
So frightened was he that he did not dare to move an inch.
2）在某些表示祝愿的句型中。例如：
May you all be happy. 愿你們都快樂。
3）在虛擬語氣條件句中從句謂語動詞有were，had，should等詞，可將if省略，把were，had，should移到主語之前，采取部分倒裝。例如：
Were I you, I would try it again. 我是你的話，就再試一次。
