楼上的回答是对的.
一、用完全倒桩主要有以下两种情况:
1.以副词here、there、now、then、thus等开头,动词为不及物动词(如come,arise,go,follow等)时,用完全倒桩;
如:Here arise another problem.这里就有产生了另一个问题.
There goes the last bus.末班车开走了.
但要注意的一点:主语为代词时,不能倒装,如:Here you are.Here it is.
2.介词短语或副词作为状语时,为了平衡结构(尤其是状语较长时),或强调状语(为了突出状语、制造悬念、烘托气氛),将状语部分提前,用完全倒桩.
二、用部分倒桩主要有以下两种情况:
1.only +状语或状语从句置于句首,句子用部分倒装,但从句内不倒装;
如:Only when you had fully understood what he said,did she realize that she had missed her Mr.Right.
2.否定词开头时,这是大家最熟悉的,不再赘述;
3.so / such...that结构中的so或such位于句首可以构成部分倒装句,表示强调so /such和that之间的部分.
如:So unreasonable was his price that everybody startled.他的要价太离谱,令每个人都瞠目结舌.
To such length did she go in rehearsal that the two actors walked out.她的彩排进行得那长,以致于那两个演员都走出去了.
