问题描述：
It was foolish of the young lady to lose her bag.这句话主语是什么?表语又在哪里?
答
主语是to lose her bag
表语the young lady
答
主语是it, 但在这里只是一个形式主语，真正的主语是to lose her bag，
表语自然就是be 动词后面的foolish了。
答
it作形式主语,young lady是真正的主语,表语是foolish 真正的句型是the young lady was foolish to lost her bag
答
it 形式主语
to lose her bag 实际主语
表语是 was foolish
