这虚拟语气当中的倒装句,就是if省略,助动词提前.would不可以.
当虚拟条件句的谓语动词含有were,should,had时,if可省略,而将were,should,had等词置于句首.如：
Should he agree to go there,we would send him there.要是他答应去的话,我们就派他去.
Were she here,she would agree with us.如果她在这儿的话,她会同意我们的.
Had he learnt about computers,we would have hired him to work here.如果她懂一些电脑知识的话,我们会已经聘用他来这里工作了
