1. 第一个句子,
为什么“Here is + 主语”这种倒装结构变成here it is就不能倒装,其原因是:如果主语是名词,那么就必须部分倒装,如:Here is your key. Here comes the bus. There has my sister been to.但是当主语是代词时,那么就成了你说的句子,如上述三句话改为代词:Here it is. Here it comes. There she has been to.倒装的主要目的是为了保持句子平衡,名词(有时候是名词短语)较长,置于动词前就会使句子显得头重脚轻,而代词组成字母较少,所以不倒装。
第二个句子:
条件虚拟语气在省去if时,必须要求部分倒装。如:
Were I you ,i would try again.(就是If I were you, I would try again.)
Should he do such a job, ...(就是If he should do the job, ...)
Had I been here. ...(就是If I had been here)
3. 其他倒装:
主要出现在否定词或半否定词提前的情况下,如:下列词提前:
no,neither,hardly,no sooner,not only, not until,only, few等。
当然其他情况也有,这里不再一一列举。
