英语高手虚拟语气符合倒退一步的有哪些

主句用一般现在,从句倒退一步用一般过去,也应该对.
I feel as if I have been in a different world.
我感觉好像置于一人世外桃源.
I felt as if my heart would burst with joy.
我觉得自己高兴得心花怒放.
She ran as if the Old Boy were after her.
她跑得飞快好像魔鬼在追她似的.
He felt as if he almost wished to kill them.
他感觉彷佛几乎要杀掉他们.
He behaves as if he had no common sense.
他的言行就好像没有常识似的.
She looks as if nothing had happened to her.
她当时看起来好像什么事都没发生似的.
He looked as if he had seen a ghost.
他好象见了鬼似的(很惊慌的样子).

可以看成从句本来是现在完成时，所以就变成了过去完成时了。It is like she has known all the secrets. She looks as if she had known all the secrets.

know是短暂动词。这里的had known 你应该理解为，她好像已经知道了一样，就是知道是以前就知道了的，这个知道是完成时，那这句话就是对过去的虚拟。英语应从具体语句意思揣摩时态，不应该死记硬背。

此问题涉及到"as if" 的两种用法
一.as if 从句用陈述语气
我这里说的从句用陈述语气,是相对于虚拟语气而言的。即你所表达的句子是真实的或极有可能发生或存在的事实时.
设想语境:比方说你现在屋里看不到外面的情况,却听到了雨滴声,表达如下:
It sounds as if it is raining． 听起来像是在下雨。
二. as if 从句...
