副詞提前倒裝

　　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(yǔ)(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 dan ger.

　　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 hight scores on the final exam. =He worked so diligently that he got

　　hight scores on the final exam.

　　Such was his wish that the world would stay away from war forever.

　　Often did we go on a holiday in hot summer. 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(guò)多的依賴于來(lái)自農(nóng)作物的收入，佛羅里達(dá)也是這樣同理，體會(huì)一下neither， nor的倒裝 He can‘t dance, neither/nor can I.= I can’t, either.

　　他不會(huì)跳舞，我也不會(huì)。

　　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(wèn)倒裝

　　疑問(wèn)句需部分倒裝語(yǔ)序，由于經(jīng)常用到不會(huì)成為考試的難點(diǎn)。

　　如：What part did he play in Hamlet?

　　Do you prefer tea or coffee?

　　by可視為被動(dòng)語(yǔ)態(tài)的標(biāo)志詞，by之后的名詞短語(yǔ)是句中動(dòng)作的施動(dòng)者;在題干中若見(jiàn)到by+名詞的結(jié)構(gòu)要優(yōu)先考慮用被動(dòng)式

　　如：The wall is painted by Tom.

　　The book was written by Mark Twain.
