1.Down fell the man.{副詞down，謂語動詞fell，主語the man}

Down he fell.{副詞down，主語是代詞he，謂語動詞fell，當主語是【代詞】的時候，無需倒裝}

諸如in /out /up /down /off /away /over /back這些【副詞】放在句首，句子就要倒裝啦

2.還有there /here /now /then /thus放在句首的時候，要全部倒裝。

Here are the books.

There goes the bell.

Now comes your turn.

There be句型是典型的完全倒裝。

3.時間地點狀語放句首的時候，句子全部倒裝。

部分倒裝 是【情態動詞/助動詞/be動詞】+【主語】+【謂語】的順序。

Only then did I realize the importance.【only+狀語then，did I realize 部分倒裝，助動詞did+主語I+謂語動詞realize】

Only in this way can you fool him.【only+狀語in this way，can you fool 部分倒裝，情態動詞can+主語you+謂語動詞fool】

Only when the class is over, can I see her.【only+when引導的狀語從句放句首，從句不倒裝，主句要到裝】

2.not until放句首

Not until midnight did it stop raining.

3.not only...but also...前倒後不倒
