常见的部分倒装结构：
(1) only+副词/介词短语/状语从句位于句首时：
I realized the importance of learning English only then。 Only then did I realize the importance of learning English。
You can learn English well only in this way. Only in this way can you learn English well.
One knows freedom’s value only when one loses it。 Only when one loses freedomdoes one know its value。
(2) 否定词或表否定意义的词：seldom, hardly, scarcely, rarely, never, little, few, neither, nor等位于句首时：
I have neverseen such a beautiful place. Never have I seen such a beautiful place。 I seldom go to the cinema. Seldom do I go to the cinema。
(3) so位于句首，并用于重复前面的部分内容，表示“某人/某事也如此”时： He has been to Beijing. So have I. I have been to Beijing too。 Helikes reading very much. So do I. I like reading too。 Notes: 1. so 引导的倒装句中的谓语与前句的谓语时态保持一致。
2. 若so引导的句子主语与前句主语一致，表示“某人确实如此”时，无需倒装。 Bettyis a pretty girl. So she is。 Tom works really hard. So he does。 (4) 含no的短语置于句首时：
In no way can we allow this to happen。 By no means should he be left alone。 In no caseare you to leave him alone。 On no accountshould we leave him alone。
Under no circumstances can we destroy our environment。 No longer are they seeing each other。 (5) not 短语位于句首时：
Not untilhe went abroad did he know the truth of the fact. (主句倒装，not until引导的从句不倒装)
Not only did I know her, but I was her best friend. (紧跟not only的句子倒装) Not a momentdid she waste when she was studying abroad。
(6) 比较状语从句中的倒装：比较结构的后面部分可以进行部分倒装，后面部分的谓语的时态与前面谓语的时态保持一致
I can run faster thanhe does. I can run faster than does he。 He ranas fast as my brother did. He ran asfastas did my brother。
The greater the number of the free electrons(电子) in a material is, the better is the conductivity(导电性) of the material.
(7) 在由so+adj/adv+that和such that引导的结果状语从句中：
He works so hard that he has made great progress in English. Sohard does he work that he has made great progress in English
The attack was so suddenly that we had no time to escape. Sosuddenly was the attack thatwe had no time to escape。
He speaks so loudly that even people in the next room could hear him. So loudly does he speak that even people in the next room could hear him。

条件句与让步状语从句中的倒装：
(8) if引导的条件句中，当谓语动词包含were/should/had时，可以省略if并且从句倒装：

If it should rain tommorow, we should put off the meeting. Should it rain tommorow, we should put off the meeting。

(9) though/as(虽然，尽管)引导的让步状语从句中的倒装：
