As early as 1647 Ohio made a decision that free, lax-supported schools must be established in every town___50 households or more. A. having B to have C.to have had D. having had

A吧

A. having

定语从句修饰town
有50或更多人家的小镇

选A。
A：having在这里与with的用法差不多，可互用；
B、C：to v也可以作后置定语，但在我看来多用于被动，如sth to eat/do/say, etc；
C、D：毋须用过去完成，因为是与主句位于同一时间的。

As early as 1647.. 请问as early as October 2007是什么意思？ as as as early as may may 作五月解，这个短语如何翻谢谢 as precious as as........as表示什么 as ...as的用法 As Long As Love not as as 造句 as soon as possible
