问题描述：
it is high time something was done about the traffic problem这个句子是不是可以理解为something为主语ait is high time something was done about the traffic problem这个句子是不是可以理解为something为主语was done是谓语about the traffic problem为定语
答
it是主语,is 是系动词,high time是表语,something到句末是定语从句,修饰high time
在定语从句中,something是主语,was done是谓语,about the traffic problem作定语,修饰something
