over a hundred people must have been driven away from their homes by the noise!

题目

over a hundred people must have been driven away from their homes by the noise!
over a hundred people must have been driven away from their homes by the noise!
这句话中的结构怎么分析,其中over a hundred people 为主语,have been driven away,表示现在完成时的被动语态,被赶走,做谓语,那么from their homes by the noise在句子的成分是什么?

答案

from their homes和by the noise是分开的
from their homes为介词短语作状语表示“从他们家里（被赶出去）”.
by the noise是被动语态中的by sb表示“被噪音”
意思就是“一百多人由于噪音而离开了他们原来的住所”
