so, neither, nor作部分倒装，表示"也"、"也不" 的句子要部分倒装。

例句：

Tom can speak French. So can Jack.

If you won't go, neither will I.

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。

解析：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"。

例句：

Tom asked me to go to play football and so I did.

-It's raining hard.

-So it is.
