1) so… that 句型中的so 位于句首時,需倒裝。

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。

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引導的倒裝句,表示前一情況的重復出現(xiàn)。其中, so用于肯定句, 而 neither, nor 用在否定句中。
