30、 / D. whom; him2. Mrs. Black took the police back to_ place _ she witnessed the robbery. A. the same; as B. the same; where C. the same ; that D. as the same; as as与which都可以引导一个非限制性定语从句，并代表前面整个句子。The elephant is like a snake, as/which everybody can see.不同的是：as引导的定语从句可以前置，而which不行。As everybody can se

34、，如fact, news, belief, truth, reply等。that在定语从句中充当成分，而that在同位语从句中不充当任何句子成分，只起连接作用。    We all have heard the news _that_ our team won. (同位语从句，that从句表示news的内容，that 在从句中不作任何成分)We dont believe the news _that/ which/ 不填_ he told us yesterday.(定语从句，that 作told 的宾语)三：定语从句与表语从句The place _ the br
