were式虚拟 英语中叫做“were式虚拟”的这种虚拟语气,通过扭曲时态形式来表示与实际情况相反的虚构假设.具体做法是将时态的形式“倒推一个时态”.这样的表述也许不太准确,但是非常实用,也极容易理解.具体的做法,就是将现在时态变成过去时态,将过去时态变成“过去的过去”.在这种虚拟语气的用法中,动词be至少要倒退一个时态成为“过去时态”的were（在虚拟语气中一般不用was、is、am、are,倒推一个时态以后都写成were）.因此,这种表示与实际情况相反的虚构假设的虚拟语气就以动词be的变化为例,叫做were式虚拟.
这个是虚拟语气的用法，were式虚拟，英语中叫做“were式虚拟”的这种虚拟语气，通过扭曲时态形式来表示与实际情况相反的虚构假设。
这是虚似语气，虚拟语气用来表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反.
if i were you是一个非条件的状语从句,用中文翻译：如果我是你.但是我不可能会变成你，所以进入虚拟语态了,就是假的.
虚拟语气表示说话人的主观愿望、猜疑、建议或与事实不符的假设等，而不表示客观存在的事实。虚拟语气是由句中的谓语从句的特殊形式表示出来的。
虚拟语气用在与现在事实相反条件句中时，条件从句的谓语用动词的过去式 （be的过去式用were），结果主句的谓语用should(第一人称)或would(第二、三人称)＋动词原形。
