副詞提至句首引起倒裝,可分以下幾種情況：
1. only + 副詞(when, before, if, after等)或only+介詞狀語(由in, under, by, on, after等引導(dǎo))提前,必須部分倒裝
如：Only then did he realize how stupid he had been.
? ? ? Only after entering the store did Arthur realize that there was danger.
? ? ? Only in the library can she concentrate on her study.
2. often, such, so等副詞提前,部分倒裝
如: So diligently did he work that he got highest scores on the final exam.
? ?=He worked so diligently that he got highest scores on the final exam.
? ? Such was his wish that the world would stay away from war forever.
? 注意,so的另一種倒裝是表示“也…”
? ? California relies heavily on income from crops, and so does Florida.加利福尼亞過多的依賴于來自農(nóng)作物的收入,佛羅里達也是這樣
　同理,體會一下neither, nor的倒裝
? ? He can't dance, neither/nor can I.= I can't, either.他不會跳舞,我也不會.
3. in, out, down, up, away, off, here, there, over等副詞提前,全部倒裝
如：Off got the staggering gentlemen.
? ? ? Here are the photos I took at the seaside.
疑問倒裝
疑問句需部分倒裝語序,由于經(jīng)常用到不會成為考試的難點.
如：What part did he play in Hamlet?
? ? ? Do you prefer tea or coffee?
