高中英语题—关于as
______ has already been pointed out,grammar is not a set of dead rules.
A.As B.It C.That D.Which
那个,选as的话不是没有主语了吗?还有,为什么Which不行,长的蛮想非限制性从句的.
我疑惑啊( ⊙ o ⊙ )

Answer 1

As这里是确实是定语从句的先行词.但是你看好,as所引导的定语从句是grammar is not a set of dead rules 也就是说,as是指代这整个后半句的.
为什么不能用which呢?因为which 后面跟的是从句部分,而这里从句部分应该是grammar is not a set of dead rules,——has already been.是主句哦.
