中考英語語法部分倒裝
部分倒裝是指將謂語的一部分如助動詞或情態倒裝至主語之前。如果句中的謂語沒有助動詞或情態動詞，則需新增助動詞do, does或did，並將其置於主語之前。
句首為否定或半否定的詞語，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
當Not until引出主從複合句，主句倒裝，從句不倒裝。
注意： 如否定詞不在句首不倒裝。
I have never seen such a performance.
The mother didnt leave the room until the child fell asleep.
典型例題
1)Why cant I smoke here?
At no time___ in the meeting-room
A. is smoking permittedB.smoking is permitted
C. smoking is it permittedD.does smoking permit
答案A. 這是一個倒裝問題。當否定詞語置於句首以表示強調時，其句中的`主謂須用倒裝結構。 這些否定詞包括no, little, hardly, seldom, never, not only, not until等。本題的正常語序是 Smoking is permitted in the meeting-room at no time.
2） Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didnt man know D. did man know
答案D. 看到Not until…的句型，我們知道為一倒裝句，答案在C，D 中選一個。
