一、only在句首要倒裝的情況，例如：
     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(fù)合句，則主句倒裝，從句不倒裝。
     Only when he is seriously ill, does he ever stay in bed.
    二、表示"也"、"也不" 的句子，so, neither, nor要部分倒裝。　　　　
    Tom can speak French. So can Jack.
    If you won't go, neither will I.
    典型例題
    ---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為增補(bǔ)意思"也不關(guān)心"，因此句子應(yīng)倒裝。A錯(cuò)在用 don't 再次否定， C neither 用法不對(duì)且缺乏連詞。D項(xiàng)缺乏連詞。
     注意：當(dāng)so引出的句子用以對(duì)上文內(nèi)容加以證實(shí)或肯定時(shí)，不可用倒裝結(jié)構(gòu)。意為"的確如此"。
     Tom asked me to go to play football and so I did.
     ---It's raining hard.　---So it is.
