1)　 so… that 句型中的so 位于句首時，需倒裝。

　　So frightened was he that he did not dare to move an inch.

　　2)　在某些表示祝愿的句型中：

　　May you all be happy.

　　3)　在虛擬語氣條件句中從句謂語動詞有were, had, should等詞，可將if 省略，把 were, had, should 移到主語之前，采取部分倒裝。

　　Were I you, I would try it again.

　　典型例題：

　　1) Not until the early years of the 19th century___ what heat is

　　A. man did know　 B. man knew　 C. didn't man know　 D. did man know

　　答案為D.　否定詞Not在句首，要求用部分倒裝的句子結(jié)構(gòu)。

　　2) Not until I began to work ___ how much time I had wasted.

　　A. didn't I realize　　B. did I realize　　C. I didn't realize　D. I realize

　　答案為B。

　　3)　Do you know Tom bought a new car?

　　I don't know, ___.

　　A. nor don't I care　 B. nor do I care

　　C. I don't care neither　D. I don't care also

　　解析：答案為B.　句中的nor引出部分倒裝結(jié)構(gòu)，表示"也不"。由 so, neither, nor引導(dǎo)的倒裝句，表示前一情況的重復(fù)出現(xiàn)。其中, so用于肯定句, 而 neither, nor 用在否定句中。
