为什么虚拟语气中的I were you不能改为I was you

为什么虚拟语气中的I were you不能改为I was you 虚拟语气中为什么要用if I were you if i were you 为什么用虚拟语气 为什么虚拟语气都是were 虚拟语气 I后面为什么要用WERE?同上 if 虚拟语气为什么if it rains tomorrow 不用if it rained tomorrow,而if i were you为什么不用if i am you?那如果说如果某样东西不属于你应该用虚拟语气么?其实我有点想问，到底什么时候用虚拟语气，什么 谁能帮忙跟我说说虚拟语气中的将来时,不知道为什么要加were to, what a beautiful place!I wish I could be there now.是虚拟语气吗?如果是虚拟语气为什么用could be ,对现在的的虚拟不应该用过去是吗?我是说COULD BE 改成WERE 行不行 if i were you i would go there虚拟语气的倒帐形式 是if i was you 还是 if i were you?那是所有虚拟语气 am 都变成 were 么? I是单数,但为什么有If I were you 这样句式虚拟语气我也知道我问的是为什么是I是单数,但为什么有If I were you 这样句式 而不是If i was you 使用虚拟语气写一篇 if i were you 的作文 “I thought you were marvelous!”是哪种形式结构的虚拟语气? 那里不应该是I were 的麽?因为那是虚拟语气啊! 虚拟语气一般过去时中的be动词为什么总用were呢?（无论人称是什么） 虚拟语气 If i were you,那“如果我是他”呢,是不是If i was he,虚拟语气的从句的谓语怎么用 虚拟语气中be动词的用法?If he fell downstairs and wasn't moving ,what would you do?其中的wasn't 为什么不是were? 虚拟语气中,应该用I was还是I were
