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 if i were a boy这首歌为什么谓语部分是were而不是单数形式?是歌词本身有错误吗? I was a boy还是I were a boy?为什么if I were you,而不是if I was you?was[wCz; wEz]be 的过去式(第一人称及第三人称单数)if she were you,... if i were a boy 为什么‘I’后面跟‘were’? if i were a 为什么if i were a boy?应该是 i was为什么是were if i were you为什么 i 后面是 were 而不是was请说明详细点 How I wish it weren't raining now中it是单数为什么用were If I were you If i were U. if i were a If i were if i were a if.i.were.a. If I were him.如果我是他,为什么用的是were,而不是was? 为什么碧昂丝的if i were a boy中的Be动词是were? If i were a boy 为什么用were啊 为什么 if i were a boy 中的were 不用was? 为什么If only I were abird.中的were不用was
