主从句怎么判断.if i were you ,i would go abroad.

i would go abroad.－－－主句
表示与现在事实的假设,不相符参考：If引导条件句 一半用一般现在时代替将来是
eg:If it rains tomorrow,I'll not go there.
if引导的虚拟语气事态需向前推
if条件句______从句动词_________主句
对现在虚拟____did,were_________would,could,should+动原
对将来虚拟____should do________would,could,should+动原
______________were to do
______________were,did(较少,常有时间状语）
对过去虚拟____had done_________would,could,should+had done后面对虚拟语气的总结 竖着看 是归纳好的
