问题：定语从句中先行词被thesame修饰,能否用where引导其定语? 
Mrs Black took the police back to () place () she wnessed the robbery.  A. the same ; as  B. the same ;where  C the same ;that   D. as the same ; as
回答：是这样的:如果引导词在宾语从句中做名词性成分(比如:主语,宾语),那必须用as,若不是这种情况(比如作状语),那该用啥词用啥词,不必限制.请看原题中,主谓宾具全,所需的是状语,当然要填where了.此题选B.再说,as没有副词的词性,不能做状语,如把as填进去那它一个名词在从句中做啥成分呢?对吧
