Theory comes from practice has long been proved

A: Theory B:comes from C: long D:proved

动词基本没问题,是句子语法问题.前面是一句话,而整句有两个VERBS.所以正确的是:That theory comes from practice has long been proved.构成主语从句~~~!!!
*_*解释地到位吗?

D:proven 我们都知道这里用的是一个完成被动时态!

proven 正是动词prove的完成时态;
Theory comes from practice has long been proven这里也等同于Theory comes from practice that has long been proven

C.long
后面应该加before

D proven

B
