在定语从句中,若从句中有被动语态,该如何分析句子成份?
That is the writer ________a lot of books were written.
A,by whom B,who c,whose D,whom
请分析句子成份,我的分不多,

A.
首先分析句子成分.
主语:That.系动词:is.表语:the writer."by whom a lot of books were written"定语从句修饰the writer.
这里的by whom 就是介词提前.相当于“whom a lot of books were written by”,由于在从句中做writeen by的宾语,故用宾格whom.
如有不懂可追问.这里的先行词是什么?the writer
