i wish i were a girl.可以换成i was么,为社么 ,社么时候用was啊 为什么是I wish I were a bird 而不是I wish I was a bird I wish I were I wish I were what I was when I wished I were what I I wish was a rockerpurk 下面这句话,为什么是I wish I was 而不是 I wish I were? I wish you were I wish I were here yesterday中为什么不用was i wish i ___rich A was B were C would be D am 选哪个,理由. theres's a girl that gives a shit是艾薇儿《I wish you were here》里 i wish you're a luck girl. I WISH I WERE A BIRD.怎么这句子里面用WERE,不用WAS啊?是不是书上写错了
