定语从句

题目

定语从句
-Did the audience participate in the play?
-Yes,the actors ______ to involve the audience were successful.
A.whom it was the functiong B.of which the function was
C.whose function it was D.whose were the function
为什么选C,不选B呢?
能帮我分析下这句句子的主句是什么?
选B的话 从句是什么?从句哪里出了问题?（我认为从句可以是the function of the actors was to involve the audience,然后of which前置,就选B)
选C的话 从句是什么?it指代什么?不用it的从句怎么写?

答案

额…那我来说一下好勒 其实一楼是正解
这题正确答案的确应选C
B不正确的理由就是which不能指代人 这是没有特例的 相信楼主的老师已经在课堂上像强调生命安全一样强调过勒
再来说C 整个句子的大结构是the actor were successful 定语从句的原貌是it was whose(actor) function to involve the audience 再把whose function提前就可以勒 其中it做形式主语 真正的主语是后面的不定式 谓语是was 即to involve the audience was whose(actor) function演员的职责是实观众参与其中
这个定语从句是一个固定句型it is/was sth.(for sb.)to do.
eg.It's a custom to eat dumpling at Spring Festival.春节吃饺子是一种习俗.
