（1）省略if
若虚拟条件句中有 were, had, should 时，可省略 if 而将 were, had, should 移到句首。如：（1）If I were to meet him tomorrow, I should ask him about it.
Were I to meet him tomorrow,…
错综时间虚拟条件句
1.If you had finished writing the book last month , it would be published next month.
（3）含蓄虚拟条件句
有时假设的情况并不以条件从句表示出来，而是通过一个介词来表示或通过上下文或其他方式表示 如“but for ”，“without ”及“but that ” “ except for和“supposing ” “otherwise等表示含蓄的虚拟：
But for your help,I would have failed.
Without the money,I would not be alive now.
