Someone in the crowd called out his name,but he couldn’t see _.A.whose B.who C.where D.which
答
b
答
可以
答
1 someone本来就是一个不定代词,被提问时,用who.(没有范围,因为不知道是谁)
2 看下面的句子：One of her friends called at her flat during her absence ,but she doesn't know which (of them) did.（有了范围----which问的是her friends中的某一个或某一些,说明有范围了）
3 -------,but he couldn’t see who did中的who并不是see的宾语,而是see后面的宾语从句部分的主语----she couldn't see who did (==called out his name).
明白了吗?
