Question

帮忙分析一下这个句子成份，主谓宾在哪里，都是什么从句起什么作用？

For the first time in his life, he became the proud owner of a bed which had springs and a mattress

Answer 1

三楼说得对，这个句子是主系表结构。
For the first time in his life作状语，强调他是第一次为了……而自豪。
he是主语，
became是系动词，
the owner 是表语，
proud和of a bed 都是修饰owner的，
which had springs and a mattress 作bed的定语从句。

Answer 2

主语是he,谓语是became,宾语是the proud owner of a bed,which had springs and a mattress是定语从句，修饰前面的bed, for the first time in his life,是时间状语。这是新概念二上的一篇文章的中的句子。

Answer 3

我觉得楼上说的不大正确
主语是he，谓语是became，宾语是owner
proud和of a bed都是定语，修饰owner
for the first time 是时间状语短语。
which had...是定语从句，修饰bed

Answer 4

呃，这个句子不是主谓宾。。。是主系表结构的。。。。
因为BECOME是一个系动词，后面的表语就是the proud owner of a bed
前面那个是时间状语说明时间的，后面那个是定语从句，作补充说明。
