部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句子的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。

1.句首为否定或半否定的词语。
如no, not, never, seldom, little, hardly, scarcely, at no time决不, by no means, on no account, in no case, many a time, under no circumstances, in no way, many a time, not until… 等。例如：
Never have I seen such a performance. 从未见过如此糟糕的表演。
Nowhere will you find the answer to this question. 无论如何你不会找到这个问题的答案的。
Not until the child fell asleep did the mother leave the room. 母亲一直到孩子入睡后离开房间。
当Not until引出主从复合句，主句倒装，从句不倒装。即：后倒前不倒。注意： 如否定词不在句首不倒装。例如：
I have never seen such a performance.
---never have I seen such a performance.
The mother didn't leave the room until the child fell asleep.
---not until the child fell asleep the mother did leave the room.

典型例题
1） Why can't I smoke here?
At no time___ in the meeting-room
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。
2） Not until the early years of the 19th century ___ what heat is.  
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型，我们知道考点为倒装句，答案在C，D 中选一个。
改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。

2．以否定连词开头作部分倒装
如 Not only…but also, Hardly/Scarcely…when, No sooner… than等，前倒后不倒。例如：
Not only did he refuse the gift, he also severely criticized the sender. 他没有收下礼物，还狠狠批评了送礼的人。
Hardly had she gone out when a student came to visit her. 她刚出门，就有个学生来访。
No sooner had she gone out than a student came to visit her. 她刚出门，就有个学生来访。
典型例题
No sooner___ than it began to rain heavily.
A. the game began B. has the game begun
C. did the game begin D. had the game begun
答案D. 以具有否定意义的副词放在句首时，一般采用倒装句（谓语前置）。
注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构，如Not only you but also I am fond of music。

3． so, neither, nor作部分倒装。
表示另一主语“也…样”时，用“So + be(have,助动词或情态动词)+主语”结构；而表示另一主语“也不…样”时，用“NorNeither + be(have,助动词或情态动词)+主语”结构。例如：
Tom can speak French. So can Jack. 汤姆会讲法语，杰克也会。
If you won't go, neither will I. 你不去，我也不去。
典型例题
---Do you know Jim quarreled with his brother?
---I don't know，_____.
A. nor don't I care B. nor do I care C. I don't care neither D. I don't care also
答案：B. nor为增补意思"也不关心"，因此句子应倒装。A错在用 don't 再次否定，C neither 用法不对且缺乏连词。D缺乏连词。
注意：当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为"的确如此"。例如：
Tom asked me to go to play football and so I did. 汤姆邀我去踢球，我去了。
---It's raining hard. ---So it is. 雨下得真大。是呀。

4．only在句首倒装的情况。only+副词；或介词短语；或状语从句时，主句倒装。例如：
Only in this way, can you learn English well. 只有这样，你才能学好英语。（only+介词短语）
Only after being asked three times did he come to the meeting. 叫了三次，他才来参加会议。
Only yesterday did he find out that his watch was missing.（only+副词）
Only when it began to rain did he finish his job.（only+状语从句）
如果句子为主从复合句，则主句倒装，从句不倒装。例如：
Only when he is seriously ill does he ever stay in bed. 病得狠重时，他才卧床休息。
