问题描述：
———the public school with private school,the guide book gives us a clear idea about the differences between them.
A.having comparing B.compared C.To compare D.To be compared
选哪个,为什么?这道题是考得独立成分吗?
答
本题考查非谓语动词作状语,the guide book 与动词compare有主动关系,这本指导书比较公立和私立学校,当然还有先后关系,句意是：在比较公立和私立学校之后,这本指导书非常清楚地指出了这两者之间的区别.所以应当选择A.Having compared,你的选项答案写错了!compared to不是可是做独立成分吗？怎么区别是独立成分还是正常的主动被动啊？
