部分倒裝是指將謂語的一部分如助動詞或情態(tài)倒裝至主語之前。如果句中的謂語沒有助動詞或情態(tài)動詞，則需添加助動詞do, does或did，并將其置于主語之前。

　　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(dāng)Not until引出主從復(fù)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 permitted B. smoking is permitted

　　C. smoking is it permitted D. does smoking permit

　　答案A. 這是一個倒裝問題。當(dāng)否定詞語置于句首以表示強調(diào)時，其句中的主謂須用倒裝結(jié)構(gòu)。 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.
