表示"也"、"也不" 的句子要部分倒装。　
Tom can speak French. So can Jack.
If you won't go, neither will I.

典型例题
---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"。
Tom asked me to go to play football and so I did.
---It's raining hard.　---So it is.
