例题
---Do you know Jim quarrelled 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".

---It's raining hard. ---So it is.
2.only在句首要倒装的情况

如果句子为主从复合句,则主句倒装,从句不倒装

3.as,though引导的倒装句
as / though引导的让步从句必须将表语或状语提前 （形容词, 副词, 分词, 实义动词提前）.
注意：
1) 句首名词不能带任何冠词.
2) 句首是实义动词, 其他助动词放在主语后.如果实义动词有宾语和状语,随实义 动词一起放在主语之前.
Try hard as he will, he never seems able to do the work satisfactorily.
注意:让步状语从句中,有though,although时,后面的主句不能有but,但是 though 和yet可连用.
4.以否定词开头作部分倒装:
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
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.
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).这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等.
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.
Not only you but also I am fond of music.

B
是正确的
only修饰状语需要倒装..
